Locked Metacarpophalangeal Joint: Case Series, Anatomical Study, and Literature Review

Main Article Content
Abstract
Objectives: To present the results of our case series, describe the anatomical study conducted, and propose a treatment protocol for this condition.
Materials and Methods: We report on nine patients treated between 2006 and 2023 who sought medical attention for loss of MCP joint extension after performing forceful manual tasks.
Results: Eight patients underwent surgical treatment, while one achieved joint release through a reduction maneuver. All patients fully recovered their range of motion without complications or recurrences.
Conclusions: MCP joint locking is an uncommon condition. As a treatment protocol, we recommend initially attempting closed reduction. If surgery is required, a palmar approach for the middle finger or a palmar-radial approach should be used, as these provide optimal exposure of the accessory collateral ligament for release and allow for the resection of the bony spur to prevent recurrence.
