[A reverse vascular autograft finger island flap. A review of 15 cases and of the literature].

The authors discuss the indications for homodigital island flap with a reverse vascular pedicle. This flap is based on the anastomoses between the radial and ulnar digital arteries. These anastomotic branches lie between the posterior wall of the tendon sheath and the periosteum to form an arch and are named the "digitopalmar arches". The vascularization of the reverse homodigital island flap is derived by using the middle transverse palmar arch. This flap was performed successfully in 14 patients involving 15 fingers to resurface amputation of the distal phalanx. In 6 cases the flap was used as an "artery" flap, and in 9 cases as a "sensitive" homodigital island flap. The pedicle in these cases was neurovascular also containing the digital nerve. The sensitivity of the flap was obtained by neurorraphy between the transposed digital nerve of the flap and the receiving digital nerve of the recipient finger. This technique achieves cover of the tactile pad in one operative stage and provides well vascularized skin allowing early mobilization. Sensation of the flap can be restored rapidly when neurorraphy of the transposed digital nerve is performed.

Reverse neurovascular homodigital island flap.

We describe a homodigital island flap with a reverse vascular pedicle based on the anastomoses between the radial and ulnar digital arteries. These anastomotic branches lie between the posterior wall of the tendon sheath and the periosteum to form the three digitopalmar arches. The vascularization of the reverse homodigital island flap is obtained using the middle transverse palmar arch. This flap was performed in 11 patients as a neurovascular "sensitive" flap, including the digital nerve in the pedicle, which was then sutured to the contralateral one at the defect. This technique achieves cover of the tactile pad in one operative stage and provides well-vascularized skin, allowing early mobilization. The quality of skin cover was confirmed in all the patients at follow-up ranging from 7 to 43 months postoperatively. We believe that the benefits of the procedure outweigh the disadvantages related to the section of the digital nerve and artery.

A comparative study of the heterodigital neurovascular island flap in thumb reconstruction, with and without nerve reconnection.

41 heterodigital neurovascular island flaps were used to cover defects of the tactile pad of the thumb in 17 years. With an average follow-up of 75.5 months, 30 patients were reviewed. 17 were treated by the original Littler technique and 13 were treated with the same flap reconstruction but with division of the digital nerve innervating the flap and re-anastomosis of this nerve to the proximal nerve end of the ulnar digital nerve of the thumb. Good aesthetic and functional results were achieved in both groups. Sensory acuity did not appear to decrease with time. The nerve reconnection technique solves the "double sensibility" phenomenon (present in 41.1% of our cases treated by the original technique), but two-point discrimination is less than that achieved by the Littler technique. Most complaints were related to the donor site such as hypertrophic scarring or scar contracture and cold intolerance, but these did not cause any real functional impairment.

Dorsalis pedis flap with vascularized extensor tendons for dorsal hand reconstruction.

We describe three cases of combined loss of skin and tendons on the dorsum of the hand treated with the use of cutaneotendinous dorsalis pedis free flap. The functional and aesthetic results are excellent in the hand and aesthetically acceptable in the foot. This technique is the first choice when the treatment of these injuries requires three or four tendon grafts.

Replantation and revascularization of large segments of the hand and forearm.

From November 1985 to July 1989, the authors performed replantation or revascularization surgery on 18 patients in whom a large segment of the upper limb between the elbow and the palm of the hand had been either completely severed (9 cases) or incompletely severed with ischemia (9 cases). The operation was successful in 16 cases, and the authors were able to clinically review 14 patients (average follow-up, 23 months). The results were analyzed using a protocol based on the following parameters: range of motion, sensation, muscle strength, cold intolerance, pain, return to work, cosmesis, and the patient's level of satisfaction. The final outcome was rated excellent in 2 cases, good in 6 cases, fair in 3 cases, and poor in 3 cases. The authors point out that recovery of sensory and motor function in replantation of large portions of the hand and forearm is often difficult. Nevertheless, the good cosmetic result, the lack of pain, and the high probability of returning to work made the patients quite satisfied with this kind of reconstructive surgery.

Operative treatment of the post-traumatic boutonnière deformity. A modification of the direct anatomical repair technique.

We report 20 cases of post-traumatic boutonnière deformity treated by a modification of the direct anatomical repair technique, particularly indicated in late cases which have complete passive motion. A swallow-tailed flap is excised from the fibrous tissue between the two ends of the central slip. The proximal one is then advanced up to the coaptation with the distal edge of the scarred capsular tissue at the insertion on the middle phalanx to which it is sutured in correct tension. Excellent results have been obtained in 72% of cases and good in 5.5%. The 16% of fair results are probably due to the fact that patients didn't use the splint post-operatively and didn't cooperative with physiotherapy.

Neurovascular island flap by the disconnecting-reconnecting technique.

The authors report nine cases of hetero-digital neurovascular island flaps raised by the "disconnecting-reconnecting" technique for defects of the tactile pad of the thumb. At an average follow-up of 25 months, all cases had good restoration of sensibility without any "double sensibility" phenomenon and patients regained good dexterity. No tender neuromata developed and donor site complications were not troublesome.

Tendinous cutaneous dorsal hand injuries. One-stage reconstruction.

The reconstruction of complex cutaneous tendinous dorsal hand injuries represents a problem that is not easy to solve. The transferral in a single surgical stage, with a single flap, of skin, tendons, and nerves, all completely vascularized, is probably the ideal solution. Between 1988 and 1999 the one-stage reconstruction method was used in 13 patients. A cutaneous tendinous dorsalis pedis free flap was used in 7 cases, and a cutaneous tendinous radial forearm island flap with an inverted flow was used in 6. The dorsalis pedis flap allows for the inclusion of 4 tendons that are completely vascularized (extensor digitorum communis), while the radial flap allows us to completely insert a single tendon (palmaris brevis) and two vascularized tendinous strips taken from the flexor carpi radialis and from the brachioradialis. All of the flaps transferred survived perfectly with good functional recovery. One-stage reconstruction that is "completely vascularized" allows us to reduce the amount of time spent in hospital, the number of operations, and above all it provides cosmetic and functional results that are close to normal. The dorsalis pedis flap is indicated in cases of cutaneous tendinous dorsal hand injuries that require the simultaneous reconstruction of three or four extensor tendons. On the other hand, the radial flap may be used in situations where it is necessary to reconstruct only 1 or 2 tendons.

Hemangioma of the hand.

The authors describe the anatomopathological and clinical findings of 24 cases of benign hemangioma of the hand. The instrumental methods used to diagnose hemangioma are discussed, and MRI imaging is given particular importance in the preoperative evaluation of the site, size, extent, and relationship with the surrounding tissues and any multiple locations of the vascular tumor. This evaluation is essential to perform a wide resection of the tumor, which is the only means of avoiding recurrence. After an average follow-up of 33 months (14-54) recurrence was observed in 7% of the cases treated.
