A patient presented with a complex Kaplan's Lesion of the thumb, characterized by dislocation with absence of any fractures. The decision to employ an open dorsal approach was based on careful preoperative clinical and radiological assessment and considerations of the lesion complexity. A detailed description of the closed reduction and open dorsal approach, including incision placement, tissue dissection, and repositioning of the joint was done, with special attention given to preserving the volar plate critical for thumb functionality. The effectiveness of this approach in managing complex Kaplan's Lesion is critically evaluated, considering both aesthetic and functional aspects. This case report emphasizes on viability of the open dorsal approach in successfully managing complex Kaplan's Lesions of the thumb. The insights gained from this case offer valuable guidance for surgeons faced with similar cases.  \nKeywords: Kaplan lesion, dorsal approach, open reduction  \nIntroduction  \nFinger dislocations account for 5% of upper extremity injuries [1] . Metacarpophalangeal joint dislocations post trauma are of rare occurrence, especially the complex irreducible variety. In 1876, Farabeuf et al. first described complex MCP dislocation in the index finger but described little about MCP dislocation in the thumb. In 1957, Kaplan described anatomy and pathophysiology of the metacarpal head of the index finger buttonholing into the tissues of the palm and reasons for the inability to reduce it closed [2, 3] . In the MCP joints, the four volar plates of the fingers and the capsules within which they lie are blended with and interconnected by the deep transverse metacarpal ligament which ties the metacarpal heads together. Dorsal to this ligament on each side of the metacarpal heads are sagittal bands that connect the volar plates to the tendon of the extensor digitorum and to the extensor expansion. These bands help stabilise the volar plates over the metacarpal heads [4] . In contrast to the volar plates of the MCP joints of the fingers, the volar plate of the thumb MCP joint is a thick structure firmly attached to the base of the proximal phalanx. It forms the bottom of a two-sided box, the sides of which are made up of the collateral ligaments. Kaplan's lesion is an uncommon kind of dorsal complicated dislocation that affects the metacarpophalangeal joint [5] . Usually, it entails the use of the index finger at the metacarpophalangeal joint. This is a case report of a rare presentation presenting a comprehensive account of the successful management of a complex Kaplan's lesion of the thumb utilizing a modified open dorsal approach and provide ","cbCaioyNayw8IgDz","https://ap.wps.com/l/cbCaioyNayw8IgDz","pdf",715009,"English","# Abstract\n# Keywords\n# Introduction\n# Materials and Methods","[{\"question\":\"What clinical features define the complex Kaplan’s lesion of the thumb in this case?\",\"answer\":\"The thumb showed dislocation with no fractures, marked deformity at the MCP joint, swelling, severe restriction of motion, and skin puckering over the palmar MCP surface.\"},{\"question\":\"Why was the open dorsal approach selected in this case?\",\"answer\":\"Closed reduction was attempted but failed, and the decision was based on careful preoperative clinical and radiological assessment considering lesion complexity.\"},{\"question\":\"What surgical elements were emphasized to preserve thumb function?\",\"answer\":\"The procedure included a dorsal incision, careful dissection to protect neurovascular bundles, division of the capsule to visualize the interposed volar plate, and repositioning while preserving the volar plate for thumb functionality.\"}]","Complex Kaplan’s Lesion of the thumb managed by an open dorsal approach - A rare case report | PDF"]
