Treating Floating Metacarpophalangeal Joint Injury with Minitype Internal and External Fixator Combined with Over-Articular Fixation

Objective: To investigate the therapy methods and effect for floating metacarpophalangeal joint injury.Methods: We treaed 42 same metacarpal and proximal interphalangeal fractures by open reduction,open debridement reduction,Li beir microplate interna fixator and minitype mixed external fixator in same metacarpophalangeal joint on 16 patients from may 2003 to may 2005.Results:Following-up period was 5 month to 12 month and the average time was 6 month.The result showed that all the 42 fractures healed,function of metacarpophalangeal joint recovered to normal.According to TAF score,42 case was find and the fine rate was 100%.Conclusion:Minitype internal and external fixator combined with Over-articular fixation was an ideal method for treating floating metacarpophalangeal joint fracture,which can get rigid fixation in early stage.Function of hand can reach to better effect,if combined with early functional exercise.
