Surgical Technique: Lateral Plate Osteosynthesis of Proximal Phalanx Fractures.

Dorsal plate fixation of proximal phalanx (PP) fractures is a conventional approach but interferes with the extensor mechanism and results in stiffness. Biomechanical studies have shown that laterally placed plates on the proximal phalanges are equally stable and rigid. This technique obviates the issue of tendon adhesion and may result in better postoperative range of motion and lower secondary procedures such as removal of implant and tenolysis. The low adoption of this technique may be related to lack of familiarity with the surgical approach. We describe our surgical technique with lateral plating of PP fractures and present our case that lateral plate osteosynthesis is an acceptable surgical fixation option for PP fractures, which extends the hand surgeon's armamentarium for more challenging and comminuted fractures.

Arterialized Posterior Interosseous Nerve Graft for Digital Neuroma.

Painful neuromas are not uncommon following nerve injury, and are especially bothersome in the hand, with severe cases resulting in significant disability. Outcomes of neuroma surgery are unpredictable regardless of technique. It is recognized that optimal soft tissue environment influences nerve healing more than the specific nerve graft technique, and it is in this context, we present a novel technique of transferring a posterior interosseous nerve graft along with vascularized synovial and fat tissue based on a branch of the posterior interosseous artery to provide healthy soft tissue for nerve healing of neuroma in continuity about the hand and digits.

Approach to Fingertip Injuries.

The fingertip is mankind's tactile interface with the physical world, from reading braille, to using touchscreens, to wielding power tools. Its special tissue architecture demands astute evaluation and meticulous surgical or nonsurgical care after injury to return patients to their preinjury level of function. Attentive deliberation of physiologic, vocational, and psychosocial factors could improve the odds of achieving satisfactory results. In this article, we explore these aspects of fingertip injury to provoke readers to examine their practices and philosophies.

External bleeding versus dermal pocketing for distal digital replantation without venous anastomosis.

Venous congestion in distal digital replantations is a common problem as suitable veins are not always available. We compared two methods of venous decongestion, external bleeding ( n = 15) and dermal pocketing ( n = 28) carried out when venous anastomosis was not possible. The findings of this small study suggest that neither method of venous decongestion is clearly better than the other. Level of evidence: IV.

Secondary Interventions for Mutilating Hand Injuries.

Care of the reconstructed hand following mutilating injury is akin to the care of a vintage car. Its mechanisms are delicate, spare parts are limited, touch-ups are required often, and a major overhaul is indicated rarely. Secondary interventions are indicated for completion of staged primary procedures, management of complications, targeted improvement of function, and enhancement of appearance of the reconstructed hand. The approach to secondary reconstruction depends on the patient's age, and vocational and recreational requirements. It is also influenced by the constant evolution of surgeons' reconstructive philosophy, experience, and technology.

Articularly placed interfragmentary screw fixation of difficult condylar fractures of the hand.

PURPOSE: To retrospectively review the outcomes of intra-articularly placed interfragmentary screws for fixation of difficult condylar fractures of the metacarpal and proximal phalangeal heads. METHODS: We placed interfragmentary screws intra-articularly in 10 patients with 11 fractures to achieve a rigid fixation construct in which the non-articular portion of the bone fragment is too small to allow a stable fixation, or where the bone fragment is entirely osteochondral. RESULTS: The mean duration of follow-up was 15.9 months (range, 6-45 mo). All fractures united within 16 weeks (average, 8.1 wk). We observed subsidence in 1 case; another patient had screw protrusion that required removal. The range of motion of the involved metacarpophalangeal joints for the metacarpal head fractures was 79° (range, 60° to 90°). The range of motion of the involved proximal interphalangeal joints for the proximal phalangeal head fractures was 86° (range, 80° to 90°). CONCLUSIONS: Intra-articularly placed interfragmentary screw fixation is a good technique for treating difficult condylar fractures of the hand.
