Digital Replantation

Restoration of motion is an important component of success in digital replantation. This is achieved only with rigid bony fixation that allows early post-operative mobilisation. In addition, the technique used should be simple and avoid excessive soft tissue stripping. These aims are difficult to achieve in amputations near the base of the proximal phalanx with existing bone fixation techniques. We describe a modification of the perpendicular loop wiring technique, where one wire loop is intra-articular, which satisfies the above criteria, and describe its application and results in two clinical cases.

Background: Proximal interphalangeal joint (PIPJ) dorsal fracture dislocations (DFD) are challenging injuries. Treatment aims to achieve stability of the PIPJ after reduction so that early motion can be initiated. We studied how increasing articular destruction would affect post reduction stability and investigate the amount of traction and PIPJ flexion needed to maintain the reduction. Methods: Increasing amounts (20%, 40% and 60%) of damage to the volar lip of the middle phalanx in cadaveric specimens were created to represent PIPJ DFD that were stable, of tenuous stability and frankly unstable. Traction forces and PIPJ flexion needed to maintain the reduction were then measured. Results: The PIPJ DFD with 20% damage were stable and did not subluxe while the one with 40% articular involvement was stable after reduction. For unstable the PIPJ with 60% involvement, the more the PIPJ was flexed, the less traction force was needed to hold the joint in reduction. For PIPJ flexion of 20 degrees, a minimum 4.4N of force is needed to maintain reduction while PIPJ flexion of 10 degrees required a minimum 5.0N of force. No amount of force could maintain PIPJ reduction if traction was performed in full extension. Conclusions: In our model, PIPJ DFD with less than 30% articular damage are stable while those with 30% to 50% of involvement have tenuous stability. For the unstable PIPJ DFD, traction obviates the need for excessive flexion of the PIPJ to maintain joint reduction. This information should be considered in treatment modalities for PIPJ DFD, as well in the design of external traction devices for the treatment of PIPJ DFD.

Several surgical options have been described to manage persistent dorsiflexion contracture at the metatarsophalangeal joint and plantarflexion contracture at the proximal interphalangeal joint of the fifth toe. We describe a minimally invasive technique for the management of this deformity. We perform a plantar closing wedge osteotomy of the 5th toe at the base of its proximal phalanx associated with a lateral condylectomy of the head of the proximal phalanx and at the base of the middle phalanx. Lastly, a complete tenotomy of the deep and superficial flexor tendons and of the tendon of the extensor digitorum longus is undertaken. Correction of cock-up fifth toe deformity is achieved using a minimally invasive approach.

The Ascension PyroCarbon prosthesis has been used in proximal interphalangeal joint osteoarthritis. The dimensions of the intramedullary distal metadiaphyseal canal (isthmus) of the proximal phalanx and the base of the middle phalanx of cadaver fingers were investigated radiographically ( n = 304) and macroscopically ( n = 152). In up to 30% of the phalanges, the isthmus was smaller than the stem of the smallest proximal component size. The distal component head was always smaller than the middle phalanx base. Insertion and success of the Ascension PyroCarbon prosthesis is strongly dependent on bone morphology. A critical examination of the isthmus in radiographs is recommended in planning. If the isthmus is clearly smaller than the smallest proximal component, insertion of the prosthesis could be inadvisable. A clear mismatch between the distal component and the middle phalanx base should be avoided due to the potential risk for late subsidence and failure of the prosthesis.

Correction of claw or hammer toe deformity can be achieved using various techniques, including proximal interphalangeal joint arthrodesis (PIPJA), flexor digitorum longus tendon transfer (FDLT), and flexor digitorum brevis transfer. PIPJA is the oldest technique, but is associated with significant complications (infection, fracture, delayed union, and nonunion). FDLT eliminates the deformity, but leads to loss of stability during gait. Flexor digitorum brevis tendon transfer (FDBT) seems to be the best surgical alternative, but it is a recent technique with still limited results. In this work, these three techniques have been analyzed by means of the finite-element method and a comparative analysis was done with the aim of extracting advantages and drawbacks. The results show that the best technique for reducing dorsal displacement of the proximal phalanx is PIPJA (2.28 mm versus 2.73 mm for FDLT, and 3.31 mm for FDBT). However, the best technique for reducing stresses on phalanges is FDLT or FDBT (a reduction of approximately 35% regarding the pathologic case versus the increase of 7% for the PIPJA in tensile stresses, and a reduction of approximately 40% versus 25% for the PIPJA in compression stresses). Moreover, the distribution of stresses in the entire phalanx is different for the PIPJA case. These facts could cause problems for patients, in particular, those with pain in the surgical toe.

Five patients were successfully treated with a modified “on-top-plasty” technique, in which a finger stump is lengthened by transfer of an adjacent amputation stump with a reverse blood flow fingerstump. This technique can be performed in the acute phase or as a secondary procedure. A conventional on-top-plasty can be performed by transfer of a partially amputated index or ring finger to the “top” of the proximal phalanx of an amputated middle finger. Alternatively, the transferred part may be used in an intercalated fashion to reconstruct the middle phalanx, using a prosthesis to reconstruct the proximal interphalangeal joint. The results, complications and disadvantages of the technique are reported. We propose this procedure for the reconstruction of the middle ring finger when a free microneurovascular toe-to-hand transfer is contraindicated or refused by the patient.

We report a rare case of open dorsal dislocation of the proximal interphalangeal joint which needed operative reduction. A 39-year-old man injured his right middle finger while playing baseball. There was a laceration on the proximal interphalangeal crease, and the condyles of the proximal phalanx protruded through the wound. The flexor tendons had slipped behind the radial condyle, and made reduction impossible. After the flexor tendons and volar plate were replaced back into their normal position, the reduction was successful. Finally, the patient had full and painless motion of the digit. We review the reported cases of this injury in the relevant literature.

Percentage Improvement

In one hundred patients with Dupuytren’s disease, one hundred and fifty-four operations were performed. The average pre-operative proximal interphalangeal joint contracture was 42° and the average percentage improvement in proximal interphalangeal joint extension at post­operative review was 41%. Fourteen amputations were performed (9.1%). The primary deformity is caused by disease involvement of the palmar fascial structures. Secondary changes may prevent correction of the deformity despite excision of the contracted fascia. The anatomy of the joint is reviewed together with the primary and secondary mechanisms of joint contracture in Dupuytren's disease. Arthrodesis, osteotomy of the proximal phalanx and joint replacement are considered as alternatives to amputation when a systematic surgical approach fails to correct the flexion contracture.
