Partial medial second toe pulp free flap and dermal substitute with skin graft for salvage reconstruction of a complete skin envelope degloving of the small finger.

Skin envelope degloving of fingers are rare injuries that require rapid care and surgical treatment. Mostly caused by ring finger injuries, these traumas include bone, tendon and neurovascular pedicle damage. The authors present an unusual case of finger degloving limited exclusively to the skin envelope, without skeletal, tendinous or vascular lesion. This rare case of skin envelope degloving rendered microsurgical revascularization impossible. The authors report the results at 12 months following salvage reconstruction combining a partial second toe pulp free flap for the volar side and a dermal substitute with a thin skin graft for the dorsum.

Emergency metacarpophalangeal arthroplasty with bone grafting for traumatic joint destruction.

Emergency arthroplasty of the metacarpophalangeal joint (MCPJ) remains a valuable treatment option in patients with MCPJ destruction but may raise challenges in the event of substantial metacarpal and/or phalangeal bone defects. We report three cases of MCPJ destruction with bone defects at the proximal first phalanx treated with emergency silicone implant arthroplasty combined with bone grafting.

Clinical and radiological outcomes following radioscapholunate fusion.

INTRODUCTION: Radioscapholunate (RSL) fusion is typically performed following wrist trauma. It addresses the pain caused by radiocarpal osteoarthritis but reduces the wrist's mobility. The objective of this study was to determine the long-term clinical and radiological outcomes of this procedure. MATERIALS AND METHODS: This was a retrospective study of all wrists operated for RSL fusion in our surgery unit over a 12-year period. The clinical analysis consisted of joint amplitudes, grip strength, pain (VAS) and functional scores (PRWE, QuickDash, Mayo Wrist Score). The radiological analysis focused on bone fusion and the presence of midcarpal osteoarthritis. RESULTS: This surgery procedure was performed on 48 wrists. Of these, 34 patients were available for review, including 6 who had subsequently undergone total wrist fusion after the RSL procedure. The average follow-up was 53 months. Flexion/extension and radioulnar deviation were 56° and 30°, respectively. Grip strength in the operated wrist was 71% of the contralateral wrist. The mean pain level was 3 out of 10. The PRWE, QuickDash and Mayo Wrist Score were 35.7, 44.5 and 57.2, respectively. Seventy-nine percent of patients were satisfied with the outcome. The fusion rate was 71%, the midcarpal osteoarthritis rate was 64% and the STT osteoarthritis rate was 46%. DISCUSSION: Reduced wrist range of motion in patients who have undergone RSL fusion helps to preserve satisfactory function in the majority of patients; however, the functional outcome scores point to some hindrance in day-to-day activities. Nonunion occurred in nearly one-quarter of patients and appears to be preventable by excision of the distal pole of the scaphoid (DPS). Midcarpal osteoarthritis develops in most wrists over the long-term and appears to be inevitable. CONCLUSION: RSL fusion is a palliative procedure that preserves some of the wrist's mobility. However, it is a difficult procedure that has a significant nonunion rate. Excision of the DPS may contribute to lowering the nonunion rate.
