Surgical excision of pedunculated supernumerary digits prevents traumatic amputation neuromas.

Nine patients divided into two groups were treated for pedunculated supernumerary digits or their sequelae. The first group consisted of three patients who had among them five traumatic amputation neuromas. In each case these lesions resulted from primary suture ligation of accessory digits in infancy. Secondary surgical excision of the vestigial digit with high ligation and retraction of the accompanying nerve tissue was required in all cases. The second group consisted of six patients who had 12 pedunculated supernumerary digits. Primary surgical excision of these digits was performed with high transection and retraction of the accompanying accessory digital nerve. All patients in this group had excellent cosmetic results with no postoperative neuroma formation. Adult family members who had undergone suture ligation of similar supernumerary digits in infancy accompanied seven of the nine patients in this series. On careful examination, each of these family members had signs and symptoms attributable to traumatic amputation neuromas. We feel identification and high transection of the accessory digital nerve is essential in the treatment of pedunculated supernumerary digits. This treatment prevents traumatic amputation neuromas and yields a better cosmetic result than the traditional method of suture ligation in infancy.

Alternatives to thumb replantation in three cases of traumatic amputation of the thumb.

Three cases of complete amputation of the thumb are reported in which the amputated distal parts were not suitable for replantation. In all cases there were either complete or incomplete amputations of other digits. Two different techniques were used for thumb reconstruction: 1) pollicization of a partially amputated digit with transposition microsurgery in case 1; and 2) replantation of a less important amputated digit to the thumb stump for cases 2 and 3. These microsurgical efforts successfully restored thumb function in all three patients.

The need for replantation surgery after traumatic amputations of the upper extremity--an estimate based upon the epidemiology of Sweden.

Reports in the literature give different views of the frequency of serious amputation injuries of the upper extremity. In Sweden the vast majority of work injuries are registered by the Swedish Labour Market Insurance. All registered serious amputation injuries of the upper extremity in Sweden (8 million inhabitants) during 1979 were investigated in this study. For comparison the frequency of all amputation injuries (work and leisure) of the upper extremity in a county of Sweden (0.4 million inhabitants) during five years (1976-1980) were studied. The overall (work and leisure) incidence in Sweden is fourteen serious amputation injuries of the upper extremity per million inhabitants annually, i.e. a total number in the country of 110 cases per year. The frequency is lower in the areas of the largest cities and substantially higher in regions with sawmills, mechanical industry and/or agriculture. Thus, estimation of the total incidence based upon single counties or smaller regions may be misleading. Replantation would have been technically possible in more than 70% of the cases, but attempts at replantation were only carried out in less than 10% of the serious cases. This study emphasizes the importance of a referral of all patients with a suitable injury of the upper extremity to microsurgically trained handsurgeons.

First metacarpal lengthening following traumatic amputation of the thumb: long-term follow-up.

Thumb amputation is a relatively frequent injury in industrial accidents, producing a significant effect on hand function. The long-term results of 18 first metacarpal elongations in patients who had had a non-replantable thumb amputation at the metacarpophalangeal level are reported. Lengthening was performed using a unilateral external fixator. After a learning curve with a high complication rate and prolonged treatment, good functional results were obtained after some technical modifications, with eight patients returning to their previous occupation, and the rest requiring a change in their job.
