Complex multiple Metacarpo phalangeal joint dislocation. Is closed reduction, a good treatment option?

Abstract

Introduction: Multiple Metacarpophalangeal (MCP) joint dislocations are relatively rare in comparison with the single Metacarpophalangeal joint dislocation in either plane with limited literature evidence. Case Report: Hereby, we present a case of 40 year old male who presented with Kaplan’s dimple sign and “double Z deformity” of his left hand following a fall onto his out stretched hand. Radiological investigation revealed Multiple MCP joint dislocations involving his left index and middle finger. The 2nd MCPJ dislocation was simple closed one while the 3rd MCPJ dislocation was compound open type. The complex multiple MCPJ dislocation was treated successfully with closed reduction under wrist block. The patient is in regular follow-up with no recurrence and good hand function at the end of one year. Conclusion: Complex multiple MCP joint dislocation can be treated successfully with closed reduction using proper reduction technique.
