Opinion by
Judge MacPhail,This is an appeal by Vincent L. Killian (Claimant) from an order of the Workmen’s Compensation Appeal Board (Board), dated September 4, 1980, which affirmed the referee’s order and decision of January 31,1980, dismissing Claimant’s claim petition.
I. History of the Proceedings
A. Initial Proceedings
It is undisputed that while working for the Heintz Division of the Kelsey Hayes Company (Employer), Claimant suffered an injury to his left hand, when the hand was caught accidentally in a press causing the amputation of four fingers. As an ultimate result of that accident which occurred on September 25, 1963, Claimant was awarded compensation for loss of use of his left hand, under the specific loss provisions of The Pennsylvania Workmen’s Compensation Act (Act).1
Several months following the accident, Claimant returned to his former job with Employer at the same *32machine. On April 28, 1968, Claimant again sustained injuries to his left hand due to a similar malfunction of the press. This second accident caused the amputation of the remaining stumps of Claimant’s previously amputated fingers.
Claimant filed a new claim petition for the second accident and the referee awarded him compensation for temporary total disability (for the months of healing following the accident) and thereafter for permanent partial disability. The Board affirmed the referee’s award, but was reversed upon Employer’s appeal to this Court.
In that prior decision, Heintz Division Kelsey Hayes Co. v. Workmen’s Compensation Appeal Board, 15 Pa. Commonwealth Ct. 391, 326 A.2d 649 (1974), we held that Claimant was not entitled to compensation for an injury to a “member that judicially does not exist.” Because Claimant had already been fully compensated for the loss of his left hand, the Court held that he could not be awarded benefits for a second loss of that same hand under the Act. The Court did hold, however, that Claimant was entitled to reasonable medical expenses since a second “accident” had occurred.
Claimant appealed from our decision and order and the Pennsylvania Supreme Court granted allocatur. The Supreme Court felt that this Court had taken an unnecessarily restrictive view of the matter. The Supreme Court2 agreed with this Court that generally Section 306(c)(1) of the Act, 77 P.S. §513(1), provides the exclusive source of compensation for all disability for loss of a hand. However, the Supreme Court reaffirmed the general rule’s sole exception, which was first enunciated by the Supreme Court in *33Lente v. Luci, 275 Pa. 217, 119 A. 132 (1922), and later was affirmed by the Commonwealth Court in Carnovale v. Supreme Clothes, Inc., 7 Pa. Commonwealth Ct. 253, 298 A.2d 640 (1973).
In Lente v. Luci, the Supreme Court recognized that there may be occasions where other parts of the body have been injured or destroyed as a result of the permanent injury. Under certain circumstances, a claimant should receive in addition to the Section 306(c) specific loss benefits, compensation for total disability under Section 306(a) of the Act, 77 P.S. §511, or compensation for partial disability under Section 306(b) of the Act, 77 P.S. §512.
The Supreme Court in Killian quoted the language of the test qualifying one for additional compensation under Section 306(a) of the Act as set forth in Lente v. Luci:
But, in these cases, where it is claimed that some other part of the body is affected, it must definitely and positively appear that it is so affected, as a direct result of the permanent injury; the causal connection must be complete, and, further, the disability must be separate and distinct from that which normally follows an injury under paragraph (c), and must endure beyond the time therein mentioned. There must be a destruction, derangement or deficiency in the organs of the other parts of the body. It does not include pain, annoyance, inconveniences, disability to work or anything that may come under the term ‘all disability,’ or normally resulting from the permanent injury. Lente v. Luci, 275 Pa. at 221-22, 119 A.2d at 133.
Killian, 468 Pa. at 207, 360 A.2d at 624. (Emphasis added.)
The Supreme Court believed that the referee or the Board should have applied the Lente test to the case *34at hand and made the necessary findings because, as the Court noted, the record contained some testimony which indicated that Claimant may have sustained a separate and distinct injury to his arm as a result of the April 28, 1968 accident.
In light of the hints of a separate and distinct injury in the record below, the Supreme Court remanded to the Board and ultimately a referee for application of the Lente test, i.e., “whether the 1968 injury solely affected Killian’s left hand or did that second injury' also affect a separate and distinct part of his body.” Killian, 468 Pa. at 209, 360 A.2d at 625.
B. Remand Proceedings
Upon remand, a referee heard additional testimony presented by both parties on the crucial issue and, after consideration of the new testimony and the evidence presented at the hearings in 1968, resolved the factual issue in Employer’s favor. The referee made the following pertinent findings of fact:
4. The incident of April 23, 1968 did not cause a ‘separate and distinct’ disability beyond the further amputation of the stumps of Claimant’s four left fingers. The other consequences of the injury of April 23, 1968 were normal results of such an injury and did not cause Claimant a disability ‘separate and distinct’ from his previously injured left hand.
5. Claimant’s injury of April 23, 1968 was confined solely to the left hand, and there was no injury or disability to any other part of Claimant’s body that is ‘separate and distinct’ from that which would normally follow from loss use of the left hand.
6. The injury of April 23, 1968 has not resulted in any destruction, derangement or deficiency in the organs of other parts of Claim*35ant’s body aside from his left hand, and Claimant’s disability and any loss of earning power result solely from his inability to use his left hand.
Based on these findings, the referee concluded that Claimant was not entitled to any additional compensation beyond the compensation already paid him for loss of use of his left hand under Section 306(c) of the Act. On January 31,1980, the referee ordered that the claim petition be dismissed.
Without receiving additional testimony, the Board issued an opinion affirming the referee’s findings of fact, conclusions of law and dismissal order. That opinion and order of the Board forms the subject of the appeal before us now.
II. Present Issues
On appeal, Claimant presents two issues for our consideration:
1) Whether or not the referee’s findings of fact were vague, non-specific and indefinite and not supported by substantial, credible evidence, so as to render the Board’s affirmance of the referee’s decision in error.
2) Whether or not the Board erred in affirming the referee’s decision that Claimant’s disability was confined to his hand, ‘when the Commonwealth Court previously held claimant had also sustained injuries to his arm.’
III. 'Discussion
The Claimant had the burden of proving before the referee that he met the Lente test, specifically that he suffered a separate and distinct disability as a result of the 1968 accident, a disability not normally resulting from specific loss of a hand. Since the referee found and the Board affirmed that Claimant failed to *36sustain his burden, our review of the Board’s decision is limited to ascertaining whether or not constitutional rights were violated, an error of law was committed, or there has been a capricious disregard of competent evidence. Harrigan v. Workmen’s Compensation Appeal Board, 40 Pa. Commonwealth Ct. 390, 397 A.2d 490 (1979).
Claimant does not allege error of law (in this instance, misapplication of the law as set forth by the Supreme Court), but attacks the referee’s findings regarding the factual inquiry he made as directed by the Supreme Court. In our examination of the referee’s findings, we must decide whether the findings exhibit a capricious disregard of competent evidence by the referee. “Capricious disregard” has been defined as a “willful, deliberate disbelief of an apparently trustworthy witness, whose testimony one of ordinary intelligence could not possibly challenge or entertain the slightest doubts as to its truth.” Gateway Coal Co. v. Workmen’s Compensation Appeal Board, 36 Pa. Commonwealth Ct. 608, 613-14, 388 A.2d 1122, 1125 (1978).
The competent medical evidence of record relating to the extent and nature of Claimant’s injuries and disability is conflicting. At the remand hearing, Claimant presented the testimony of Dr. Jacob Krause, an orthopedic surgeon, who had examined Claimant on June 1, 1977. In Dr. Krause’s opinion, Claimant suffered a 25% permanent disability as a result of the 1968 (second) injury. Dr. Krause expressed his belief that the 1968 accident caused atony and atrophy of the Claimant’s upper left arm, tenderness to pressure over Claimant’s medial and lateral humeral epicondyle, and a chronic sprain situation of Claimant’s left shoulder rotator cuff mechanism. In Dr. Krause’s opinion all of these problems were the result of Claimant’s inability to use his left hand and/ *37or the abnormal manner in which he had to use his left hand and arm after the 1968 accident. Dr. Krause admitted, however, that atrophy and atony are natural concomitants of the inability to use or lack of use of a member, and that the pain and other abnormalities in the Claimant’s left arm flowed as well from Claimant’s inability to use the extremity.
Employer on the other hand presented the testimony of Dr. Martin Beller, an orthopedic surgeon, who had examined Claimant on February 21, 1978. Dr. Beller testified that in his opinion Claimant did not sustain a separate and distinct injury to any part of the body other than his left hand and particularly did not suffer from any functional impairment of the left upper extremity.
At the initial hearing on the 1968 accident claim petition, Claimant had presented the testimony of Dr. William A. Tomasco, a general surgeon, who opined that Claimant suffered a 25% permanent disability, which was a disability apart from the loss of the use of the hand for which he was previously compensated. Dr. Tomasco did concede, however, that there would have been some degree of atrophy in the forearm and tendons even without the second accident.
In the introduction to his decision on remand, the referee stated that he had considered the competent testimony of Doctors Tomasco, Beller and Krause. It is clear from the findings of fact that the referee chose to accept the Employer’s evidence as more credible, and thus found simply that Claimant had failed to sustain his burden of proving a separate and distinct injury under the Lente requirements.3 The referee’s *38reliance on Employer’s evidence does not constitute a capricious disregard of Claimant’s competent evidence, because it is obvious that the referee considered all evidence presented. In a workmen’s compensation case, the weighing of the testimony is solely within the province of the referee and his decision to accept the testimony of one competent medical witness over another will not be disturbed on appeal. Modern Transfer v. Workmen’s Compensation Appeal Board, 47 Pa. Commonwealth Ct. 592, 408 A.2d 900 (1979). A referee may accept or reject the testimony of any witness in whole or in part. Bell v. Workmen’s Compensation Appeal Board, 53 Pa. Commonwealth Ct. 156, 417 A.2d 273 (1980). This Court is bound by findings of fact such as these which are clearly the result of resolutions of conflicts in the testimony rather than a capricious disregard of competent evidence. Yellow Cab Co. v. Workmen’s Compensation Appeal Board, 37 Pa. Commonwealth Ct. 337, 390 A.2d 880 (1978).
Furthermore, the referee’s findings are sufficiently clear, specific and definite. Findings of fact in a workmen’s compensation case need not be so specific as to provide a thorough explanation of the thought processes of the fact-finder, but they must be sufficient to demonstrate that the fact-finding function was performed. Peoples Gas Heating Co. v. Workmen’s Compensation Appeal Board, 33 Pa. Commonwealth Ct. 530, 382 A.2d 484 (1978). It is readily apparent from the referee’s findings and discussion, together with the record, that the referee performed *39his function. Moreover, the findings are adequate to enable us on review to determine that the referee did not capriciously disregard competent evidence.
We turn to Claimant’s second argument regarding the intial decision of this Court. Claimant argues that the referee has ignored our first opinion, Heintz Division Kelsey Hayes Co., in which we found that there was ample competent evidence to support a finding that Claimant suffered disability as a result of the 1968 accident. Although this Court did sustain the original referee’s findings that Claimant suffered atrophy of the wrist and forearm and a 25% permanent disability, the referee did not hold (and thus we could not affirm) that the disability was separate and distinct from that involved in the loss of the hand. The lack of and necessity for such a factual finding in the referee’s decision was recognized by the Supreme Court and was the sole reason for remand. To say that the referee ignored this Court’s statements as to Claimant’s disability is to say the Supreme Court ignored our statements, which the Supreme Court obviously did not do. Thus, we find no fault with the referee’s and Board’s decisions.
There being no capricious disregard of competent evidence, we affirm the Board’s order dismissing the instant claim petition.
