[The intermetacarpal double pinning in the surgical treatment of Bennett fracture (report of 24 cases)]

Abstract

Objectives: The interest of this work is to show the benefits of surgical treatment of Bennett fractures by intermetacarpal double pinning.

Patients and methods: It is a retrospective study of 24 cases of Bennett fracture treated by intermetacarpal double pinning, between January 2005 and December 2009. The treatment was surgical for all patients. The intermetacarpal double pinning using the technique of Iselin has been reserved for fractures with small fragment found in the series in 18 cases (72% of operated patients), and by Tubiana in six cases (24%).

Results: After a mean of 36 months, we could follow only 21 patients, the evaluation of results was based on clinical criteria relevant to pain, mobility and the pinch grip, and on criteria after radiological analysis of radiographs specific trapezo-metacarpal. All fractures were consolidated. Two cases of moderate osteoarthritis were observed. Overall, the results were excellent in 15 patients (71%), good in four patients (19%) and poor in two patients (10%).

Conclusion: Intermetacarpal double pinning is a technique of choice in surgical treatment of Bennett fracture. It ensures a good closed reduction and a satisfactory functional result.
