[Osteosynthesis with resorbable hemi-cerclage in metacarpal fractures]

The use and results of biodegradable hemicerclages for metacarpal fracture fixation were reviewed retrospectively. A total of 92 metacarpal fractures in 78 patients were treated with polyglycolic or polydioxanon sutures. Study parameters included time for bony union, duration of immobilisation, total active range of motion, and complications. The hemicerclage achieved rigid fracture fixation and permitted early mobilisation exercises without jeopardizing bony union. Immobilization of metacarpals was performed for a median of 3.4 (1.5 to 6) weeks. There were no complications of wound healing. Adequate bony union was achieved after a median of 4.5 weeks (3.5 to 7 weeks). In one case, premature loading of the fracture led to displacement and delayed union. At the end of treatment (6.1 [4 to 7.5] weeks), total active range of motion was 98 (85 to 100)%. Ideal indications are oblique or torsion fractures of the metacarpals. In these cases, immobilisation up to wound healing is sufficient.
