ATTORNEY FOR THE BOARD J.M. Daley, Associate Counsel INTRODUCTION The veteran had recognized service from December 1944 to March 1946. This matter is before the Board of Veterans' Appeals (Board) on appeal from a rating decision of the Department of Veterans Affairs (VA) Regional Office (RO), located in Manila, Philippines. FINDING OF FACT The competent and probative evidence of record shows that residuals of a shrapnel wound to the right shoulder consist of a retained metallic foreign body, a healed scar, and injury to Muscle Group III causing a limitation of right shoulder motion due to pain and stiffness that is no more than moderately disabling. CONCLUSION OF LAW The criteria for an evaluation in excess of 20 percent for service-connected residuals of a shrapnel wound to the right shoulder, with a retained metallic foreign body and injury to Muscle Group III, have not been met. 38 U.S.C.A. §§ 1155, 5107(b) (West 1991); 38 C.F.R. §§ 4.56, 4.73, Diagnostic Code 5303 (1999). REASONS AND BASES FOR FINDING AND CONCLUSION Factual Background Available service records indicate incurrence of a shrapnel wound to the right shoulder, without detailed clinical findings or diagnoses. A private record dated in July 1965 includes note of partial immobility of the right shoulder joint residual to a shrapnel wound. In March 1991, the veteran presented for a VA examination. Examination revealed a healed scar on the right shoulder "w/ tenderness; adherent, depressed" and "severe" limitation of right shoulder motion. The examiner stated that no motion was possible due to pain. No neurologic deficit was noted. An X-ray revealed a metallic foreign body in the right shoulder girdle and an osseous fragment, the latter stated to possibly be from the spinous process of the scapula. The impression was shrapnel wound to the right shoulder with metallic foreign body and osseous fragment. A photograph was taken at that time and the veteran's signature was obtained. In a rating decision dated in November 1993, the RO established service connection for residuals of a shrapnel wound to the right shoulder, and assigned a 20 percent evaluation, effective October 18, 1989, the date of the veteran's reopened claim. The RO stated that although there was a finding of severe limitation of motion at the time of 1991 examination, the corresponding radiologic evidence was incompatible with examination findings, showing no malunion, nonunion or any bone deformity to produce such a degree of limitation. The RO stated that the assigned evaluation was based on moderate muscle injury to the shoulder. In a statement received in January 1994, the veteran stated that his right arm was his major extremity. The claims file contains a private medical record dated in April 1994, noting severe traumatic arthritis of the right shoulder, severe neuritis and right shoulder arm syndrome. A report of x-ray indicates the presence of a foreign body lodged at the synovial cavity, at the superior border of the right humeral head. In a statement received in April 1994, the veteran stated that due to his right shoulder he was not able to work after the war and that the pain in his shoulder affected his entire body. He argued that he warranted assignment of a 100 percent rating, with unemployability. In his substantive appeal, received in September 1994, the veteran presented argument relevant to his pain and his reduced employment capacity. He again argued that he is right-handed. The veteran also presented argument to the effect that physicians had advised him that removal of the retained fragment could result in paralysis. The veteran's signature appears on a statement dated as late as April 1996. In September 1996, subsequent to the RO's requests for release of private medical evidence and requests that the veteran report for a VA examination, the Board remanded the claim to ensure that every attempt was made to associate relevant records and that the veteran was properly notified of the need for examination and informed of the consequences of his failure to report for such. Thereafter, the RO again requested the veteran to provide evidence and/or release pertinent to treatment and/or evaluation by private physicians; he did not respond. The RO further scheduled the veteran for a VA examination in July 1997 and advised him of the same. The veteran failed to report, but, in a statement received in August 1997, he requested that the examination be rescheduled. He reported that he had been hospitalized due to a swollen right shoulder affecting the right half of his body, and had been released in December 1996. He stated that he had been unable to move due to the pain. His son signed on his behalf, identifying the veteran as a bedridden claimant. In October 1997, the veteran reported for a VA examination, with subjective complaints of right shoulder pain and limitation of motion. The VA examiner reviewed the claims file. It was noted that the veteran had suffered a cerebrovascular accident in 1996, resulting in paralysis on the right half of his body. The examiner noted that the veteran's right shoulder was stiff and the right upper extremity muscles were atrophied, with contraction of the right hand. The examiner identified damage to Muscle Group III and noted a scar near the coracoid process of the right shoulder. There was no noted damage to the tendons, bones, joints or nerves. There was no evidence of adhesions. Strength was stated to be Grade 0 due to hemiparesis on the right side of the body. The examiner indicated that there was pain with motion. The examiner concluded that "[i]t would be difficult to differentiate whether weakness, stiffness, incoordination..." were secondary to the shrapnel wound or to the veteran's stroke, but summarized that the right upper extremity was completely flail and that the right shoulder and hand were stiff. Photographs of the veteran in a supine position were taken at that time and he signed with his left thumbprint. In November 1997, the RO again asked the veteran to comply with the request for release of hospital records pertinent to his May and December 1996 hospitalization; the veteran did not respond. In July 1998, the Board again remanded the claim to obtain private records relevant to the veteran's right-sided stroke, and for VA examination to distinguish the residuals of a shrapnel wound from stroke residuals. The RO provided the veteran with release forms for the medical care providers in question. He did not respond, nor did he report for examinations scheduled in February 1999. Of record is a private physician's statement dated in June 1999. The physician advised that the veteran's present condition had started three years "PTC" as right sided body paralysis associated with right shoulder and other joint pains for which he had taken various medications and physical therapy had been recommended. The relevant impression was cerebrovascular disease (CVD), old, probably thrombotic, left "MCA" with right hemiplegia. The physician also noted the veteran had flexion contractures and degenerative joint disease with multiple joint involvement. A VA examination was rescheduled for June 1999. Photographs of the veteran taken at that time demonstrate him to be in a supine position. The report of VA joints examination, dated in June 1999, notes subjective complaints of right shoulder stiffness, without complaints of dislocation or recurrent subluxation. The orthopedic examiner noted that the veteran had had a stroke in 1996, and that since that time he had had difficulty using his right upper extremity, with marked stiffness of his right shoulder and elbow and development of contractures in the hand. The examiner further noted that the veteran had been bedridden ever since. The veteran had zero to 40 degrees shoulder flexion, zero to 70 degrees abduction, rotation, both external and internal from zero to 20 degrees, and elbow flexion from 30 to 90 degrees. The examiner noted atrophy of the right shoulder muscles and an entry wound in the intraclavicular area of the right shoulder. The examiner further noted marked stiffness of the right hand. The orthopedic examiner commented that the long- term effect of the wound to the right shoulder should be stiffness due to prolonged immobilization and lack of exercise and post traumatic arthritis with a foreign body inside the joint. However, the examiner commented that prior to the stroke the veteran was able to write, and able to move his shoulder, hands, and elbows, but that the stiffness became more marked, especially over the fingers, after the stroke. The orthopedic examiner concluded that if the stroke had not occurred, the veteran would have had a "slight deterioration of function of the shoulder, but this was markedly aggravated by the stroke." The June 1999 report of VA muscle examination notes damage to Muscle Group III. The examiner noted no sensitivity or tenderness to the scar, and no adhesions or tendon damage. The veteran's muscle strength was stated to be Grade 3/5. The examiner commented that there was a loss of muscle function secondary to stroke. The June 1999 report of neurologic examination notes that the right upper and lower extremities were less active than on the left; that the veteran had contractures of the elbow and hand on the right upper extremity; and that he responded to gross pain stimuli on all four extremities. The diagnosis was status post cerebral infarction on the left with contractures, and that there was no evidence of weakness of the right upper extremity prior to the veteran's stroke based on review of previous examination and pictures on file. Pertinent Criteria Handedness for the purpose of a dominant rating will be determined by the evidence of record, or by testing on VA examination. Only one hand shall be considered dominant. The injured hand, or the most severely injured hand, of an ambidextrous individual will be considered the dominant hand for rating purposes. 38 C.F.R. § 4.69 (1999). In considering the residuals of injury, it is essential to trace the medical-industrial history of the disabled person from the original injury, considering the nature of the injury and the attendant circumstances, and the requirements for, and the effect of, treatment over past periods, and the course of the recovery to date. 38 C.F.R. § 4.41 (1999). Evaluation of injury includes consideration of resulting impairment to the muscles, bones, joints and/or nerves, as well as the deeper structures and residual symptomatic scarring. See 38 C.F.R. §§ 4.44, 4.45, 4.47, 4.48, 4.49, 4.50, 4.51, 4.52, 4.53, 4.54 (1999). Muscle Group damage is categorized as mild, moderate, moderately severe and/or severe and evaluated accordingly. 38 C.F.R. § 4.56. In that regard, the Board is aware that the rating criteria for muscle group injuries were changed, effective July 3, 1997. See 38 C.F.R. §§ 4.55-4.73 Diagnostic Codes 5301-5329; 38 C.F.R. §§ 4.47-4.54, 4.72 were removed and reserved). The defined purpose of these changes were to incorporate updates in medical terminology, advances in medical science, and to clarify ambiguous criteria. The comments also clarify that these were not intended as substantive changes. See 62 Fed. Reg. No. 106, 30235-30237. As revised, 38 C.F.R. § 4.56 now provides as follows: (a) An open comminuted fracture with muscle or tendon damage will be rated as a severe injury of the muscle group involved unless, for locations such as in the wrist or over the tibia, evidence establishes that the muscle damage is minimal; (b) A through-and-through injury with muscle damage shall be evaluated as no less than a moderate injury for each group of muscles damaged; (c) For VA rating purposes, the cardinal signs and symptoms of muscle disability are loss of power, weakness, lowered threshold of fatigue, fatigue-pain, impairment of coordination and uncertainty of movement; (d) Under Diagnostic Codes 5301 through 5323, disabilities resulting from muscle injuries shall be classified as slight, moderate, moderately severe or severe as follows: (1) Slight disability of muscles. (i) Type of injury. Simple wound of muscle without debridement or infection. (ii) History and complaint. Service department record of superficial wound with brief treatment and return to duty. Healing with good functional results. No cardinal signs or symptoms of muscle disability as defined in paragraph (c) of this section. (iii) Objective findings. Minimal scar. No evidence of fascial defect, atrophy, or impaired tonus. No impairment of function or metallic fragments retained in muscle tissue. (2) Moderate disability of muscles. (i) Type of injury. Through and through or deep penetrating wound of short track from a single bullet, small shell or shrapnel fragment, without explosive effect of high velocity missile, residuals of debridement, or prolonged infection. (ii) History and complaint. Service department record or other evidence of in-service treatment for the wound. Record of consistent complaint of one or more of the cardinal signs and symptoms of muscle disability as defined in paragraph (c) of this section, particularly lowered threshold of fatigue after average use, affecting the particular functions controlled by the injured muscles. (iii) Objective findings. Entrance and (if present) exit scars, small or linear, indicating short track of missile through muscle tissue. Some loss of deep fascia or muscle substance or impairment of muscle tonus and loss of power or lowered threshold of fatigue when compared to the sound side. (3) Moderately severe disability of muscles. (i) Type of injury. Through and through or deep penetrating wound by small high velocity missile or large low- velocity missile, with debridement, prolonged infection, or sloughing of soft parts, and intermuscular scarring. (ii) History and complaint. Service department record or other evidence showing hospitalization for a prolonged period for treatment of wound. Record of consistent complaint of cardinal signs and symptoms of muscle disability as defined in paragraph (c) of this section and, if present, evidence of inability to keep up with work requirements. (iii) Objective findings. Entrance and (if present) exit scars indicating track of missile through one or more muscle groups. Indications on palpation of loss of deep fascia, muscle substance, or normal firm resistance of muscles compared with sound side. Tests of strength and endurance compared with sound side demonstrate positive evidence of impairment. (4) Severe disability of muscles. (i) Type of injury. Through and through or deep penetrating wound due to high- velocity missile, or large or multiple low velocity missiles, or with shattering bone fracture or open comminuted fracture with extensive debridement, prolonged infection, or sloughing of soft parts, intermuscular binding and scarring. (ii) History and complaint. Service department record or other evidence showing hospitalization for a prolonged period for treatment of wound. Record of consistent complaint of cardinal signs and symptoms of muscle disability as defined in paragraph (c) of this section, worse than those shown for moderately severe muscle injuries, and, if present, evidence of inability to keep up with work requirements. (iii) Objective findings. Ragged, depressed and adherent scars indicating wide damage to muscle groups in missile track. Palpation shows loss of deep fascia or muscle substance, or soft flabby muscles in wound area. Muscles swell and harden abnormally in contraction. Tests of strength, endurance, or coordinated movements compared with the corresponding muscles of the uninjured side indicate severe impairment of function. If present, the following are also signs of severe muscle disability: (A) X-ray evidence of minute multiple scattered foreign bodies indicating intermuscular trauma and explosive effect of the missile. (B) Adhesion of scar to one of the long bones, scapula, pelvic bones, sacrum or vertebrae, with epithelial sealing over the bone rather than true skin covering in an area where bone is normally protected by muscle. (C) Diminished muscle excitability to pulsed electrical current in electrodiagnostic tests. (D) Visible or measurable atrophy. (E) Adaptive contraction of an opposing group of muscles. (F) Atrophy of muscle groups not in the track of the missile, particularly of the trapezius and serratus in wounds of the shoulder girdle. (G) Induration or atrophy of an entire muscle following simple piercing by a projectile. 38 C.F.R. § 4.56. In pertinent part, 38 C.F.R. § 4.55, as amended at 62 Fed. Reg. 30235 (June 3, 1997), is as follows: (a) A muscle injury rating will not be combined with a peripheral nerve paralysis rating of the same body part, unless the injuries affect entirely different functions. (b) For rating purposes, the skeletal muscles of the body are divided into 23 muscle groups in 5 anatomical regions...6 muscle groups for the shoulder girdle and arm (Diagnostic Codes 5301 through 5306); 3 muscle groups for the forearm and hand (Diagnostic Codes 5307 through 5309).... (c) There will be no rating assigned for muscle groups which act upon an ankylosed joint, with the following exceptions: ...(2) In the case of an ankylosed shoulder, if muscle groups I and II are severely disabled, the evaluation of the shoulder joint under Diagnostic Code 5200 will be elevated to the level for unfavorable ankylosis, if not already assigned, but the muscle groups themselves will not be rated. (d) The combined evaluation of muscle groups acting upon a single unankylosed joint must be lower than the evaluation for unfavorable ankylosis of that joint, except in the case of Muscle Groups I and II acting upon the shoulder. (e) For compensable muscle group injuries which are in the same anatomical region but do not act on the same joint, the evaluation for the most severely injured muscle group will be increased by one level and used as the combined evaluation for the affected muscle groups. (f) For muscle group injuries in different anatomical regions which do not act upon ankylosed joints, each muscle group injury shall be separately rated and the ratings combined under the provisions of 38 C.F.R. § 4.25 (1999). 38 C.F.R. § 4.73, Diagnostic Code 5303 pertains to impairment of Muscle Group III, consisting of the pectoralis major or clavicular muscle and the deltoid. Such function with respect to the elevation and abduction of the arm to level of shoulder; and, act with the pectoralis major and the latissimus dorsi and teres major of Muscle Group II in forward and backward swinging of the arm. A zero percent evaluation is warranted for slight impairment of either the major or minor extremity. A 20 percent evaluation is warranted for moderate impairment of either arm, or for moderately severe impairment of the minor arm. A 30 percent evaluation is warranted for moderately severe impairment of the major arm, and for severe impairment of the minor arm. A 40 percent evaluation is warranted for severe impairment of the major arm. Id. Also relevant to the instant appeal is 38 C.F.R. § 4.71a. Under the laws administered by VA, disabilities of the shoulder and arm are rated under Diagnostic Codes 5200 through 5203 (1999): Diagnostic Code 5200 rates favorable ankylosis of the scapulohumeral joint with abduction to 60 degrees, reaching the mouth and head, as 30 percent for the major arm. Ankylosis that is intermediate between favorable and unfavorable ankylosis warrants a 40 percent evaluation. Unfavorable ankylosis with abduction limited to 25 degrees is assigned a 50 percent evaluation. 38 C.F.R. § 4.71a, Diagnostic Code 5200. Diagnostic Code 5201 provides that limitation of motion of the major arm at shoulder level warrants a 20 percent disability rating. Limitation of motion of the major arm midway between the side and shoulder level warrants a 30 percent disability rating. When motion is limited to 25 degrees from the side a 40 percent rating is warranted. 38 C.F.R. § 4.71a, Diagnostic Code 5201. Normal ranges of upper extremity motion are defined by VA regulation as follows: forward elevation (flexion) from zero to 180 degrees; abduction from zero to 180 degrees; and internal and external rotation to 90 degrees. See 38 C.F.R. § 4.71, Plate I (1999). 38 C.F.R. § 4.71a, Diagnostic Code 5202 pertains to other impairment of the humerus. A 20 percent evaluation is warranted for impairment of the major extremity caused by malunion resulting in moderate deformity, or by infrequent episodes of dislocation at the scapulohumeral joint and guarding of movement at the shoulder level. Frequent episodes of dislocation and guarding of all arm movements warrants assignment of a 30 percent evaluation. A 50 percent evaluation is assigned where there is fibrous union, a 60 percent evaluation is warranted for nonunion or a false flail joint, and an 80 percent evaluation is warranted for loss of the humeral head (a flail shoulder). 38 C.F.R. § 4.71a, Diagnostic Code 5203 pertains to impairment of the clavicle or scapula. A maximum 20 percent evaluation is warranted for clavicular or scapular dislocation. 38 C.F.R. § 4.71a, Diagnostic Code 5010 (1999) applies to traumatic arthritis and provides that such is evaluated based on limitation of motion of the affected part, like degenerative arthritis. See 38 C.F.R. § 4.71a, Diagnostic Code 5003 (1999). Where the limitation of motion of the specific joint or joints involved is noncompensable, under the applicable diagnostic codes, a rating of 10 percent is warranted where arthritis is shown by x-ray and where limitation of motion is objectively confirmed by evidence of swelling, muscle spasm, or painful motion. 38 C.F.R. § 4.71a, Diagnostic Code 5003 (1999). 38 C.F.R. § 4.118, Diagnostic Codes 7803, 7804 and 7805 (1999) pertain to scars. A 10 percent evaluation is warranted for superficial, poorly nourished scars with repeated ulceration under Diagnostic Code 7803. Diagnostic Code 7804 provides that a 10 percent disability evaluation is warranted for superficial scars that are tender and painful on objective demonstration. Diagnostic Code 7805 otherwise provides that a rating for scars is based upon the limitation of function of the affected part. 38 C.F.R. § 4.118. Pyramiding, that is the evaluation of the same disability, or the same manifestation of a disability, under different diagnostic codes, is to be avoided when rating a veteran's service-connected disabilities. 38 C.F.R. § 4.14 (1999). It is possible for a veteran to have separate and distinct manifestations from the same injury which would permit rating under several diagnostic codes. The critical element in permitting the assignment of several ratings under various diagnostic codes is that none of the symptomatology for any one of the conditions is duplicative or overlapping with the symptomatology of the other condition. See Esteban v. Brown, 6 Vet. App. 259, 261-62 (1994). Analysis In general, allegations of increased disability are sufficient to establish well-grounded claims seeking increased ratings. Proscelle v. Derwinski, 2 Vet. App. 629 (1992). In the instant case, there is no indication that there are additional records which have not been obtained and which would be pertinent to the present claims. To the extent that the claims file suggests the existence of potentially relevant private records, the veteran has been requested to provide release for them, but did not respond. See Counts v. Brown, 6 Vet. App. 473 (1994). The Board also notes that the veteran has recently been examined in connection with his claim. Thus, no further development is required in order to comply with VA's duty to assist mandated by 38 U.S.C.A. § 5107(a). The veteran claims that his in-service injury to his right shoulder was so severe that he was unable to work subsequent to service. He is currently assigned a 20 percent evaluation under Diagnostic Code 5303. Under that code a 20 percent evaluation for the major arm, the veteran's right arm, contemplates moderate muscle impairment affecting arm motion. Pertinent to muscle injuries, the Board first notes that pursuant to VAOPGCPREC 11-97 (March 25, 1997), where a regulation is amended during the pendency of an appeal to the Board, the Board must first determine whether the amended regulation is more favorable to the claimant than the prior regulation, and, if it is, the Board must apply the more favorable provision. See Dudnick v. Brown, 9 Vet. App. 397 (1996) (per curiam); Karnas v. Derwinski, 1 Vet. App. 308 (1991). After review of the provisions in effect prior to July 3, 1998, and the new criteria effective thereafter, the Board finds that there is no substantive difference between the applicable provisions, that neither of the criteria is deemed to be more favorable to the veteran than the other, and the Board therefore will apply the new criteria. In the instant case no detailed records created contemporary to the veteran's injury are available; thus, evaluation must be based on available service medical notations alongside subsequent results of examination and evaluation of his right upper extremity. Unfortunately, the history of the veteran's disability status remains unclear even with review of available records. The earliest, relevant, post-service record in the existing claims file notes only partial immobility of the right shoulder joint, without setting out specific degrees of motion, or findings pertinent to muscle, bone or other impairment. Such does not, therefore, serve as sufficient evidence to warrant assignment of more than a 20 percent evaluation under the schedular criteria pertinent to limitation of arm motion or muscle injuries. The first comprehensive examination findings of record, dated in 1991, also do not include motion ranges; rather, the VA examiner indicated that, due to pain, no motion was possible. That examiner did not comment on any other factors contemplated under 38 C.F.R. §§ 4.56, 4.73, such as atrophy, weakness, incoordination and did not indicate a pathology other than pain that would impact the veteran's motion. The private record, dated in April 1994, similarly does not include motion ranges. Notably, one of the VA examination reports dated in June 1999 indicated right shoulder motion limited only to 40 degrees flexion and 70 degrees abduction, below shoulder level. Such findings are based on examination reportedly conducted after the veteran was paralyzed from a stroke. The Board has considered the 1991 notation that the veteran had no shoulder motion due to pain, but finds that conclusion to be unsupported by the evidence of record. However, the 1991 VA examiner did not identify any pathology relevant to the veteran's shoulder in terms of changes in the muscle, bone or nerve structures. Nor did that examiner comment on such factors as atrophy, weakness, or incoordination. The 1965 findings showed only partial immobilization of the shoulder, not total. Also significant is the veteran's apparent lack of treatment for his right upper extremity for many years after service. Also, by his own report, he was able to write with his right hand prior to his stroke, indicating some movement. Moreover, the June 1999 examination reports contain opinions that prior to his stroke the veteran probably suffered from no weakness and only slight deterioration of shoulder function. Those reports indicate that based on the veteran's history, photographs and other medical evidence, his stroke exacerbated his right shoulder symptoms, and that it was the stroke that led to right-sided paralysis. Thus, there is no competent and probative evidence showing that the service-connected disability is manifested by loss of motion significant enough to warrant assignment of more than a 20 percent evaluation under Diagnostic Codes 5201, 5303. With regard to the muscle codes, Diagnostic Code 5303 provides for a 20 percent evaluation where there is moderate muscle damage. Evidence of record notes symptoms of stiffness and limited motion residual to the shell fragment wound, without notation of factors attributable to muscle impairment. Rather, the competent evidence, to include the June 1999 examination reports, again indicates that the veteran's stroke resulted in right-sided hemiparesis, weakness, fatigue, stiffness, etc. Such symptoms are not attributable to the veteran's service-connected disability and thus cannot be the basis upon which to assign a higher evaluation. See 38 C.F.R. § 4.73. The Board also notes that the competent and probative evidence is absent findings of an open comminuted fracture mandating assignment of a percentage evaluation for severe disability. See 38 C.F.R. § 4.56. The Board further notes that although examination in 1991 noted some tenderness and adherence of the veteran's shell fragment wound scar, the examiner indicated that the scar was healed. Available subsequent records are consistent in showing the veteran's scar to be asymptomatic. Thus, no increased or separate evaluation is warranted based on scarring. See 38 C.F.R. § 4.14. Also, there is no competent evidence of nerve involvement coincident with the veteran's service injury, subsequent neurologic pathology to support a finding of nerve impairment, or a competent opinion showing that the veteran had neurologic impairment attributable to the gunshot wound to warrant consideration under 38 C.F.R. § 4.124a (1999). Consideration has also been given to the potential application of the various provisions of 38 C.F.R. Parts 3 and 4 (1999), whether or not they were raised by the veteran, as required by Schafrath v. Derwinski, 1 Vet. App. 589 (1991). However, the Board finds no basis upon which to assign a higher disability evaluation. ORDER An evaluation in excess of 20 percent for service-connected residuals of a shrapnel wound to the right shoulder with a retained metallic foreign body and injury to Muscle Group III, is denied.
