Proximal fractures of the fifth metacarpal: a retrospective analysis of 25 operated cases.

The clinical and radiological outcomes of 25 surgically treated fractures of the proximal third of the fifth metacarpal were retrospectively analysed. Many different methods of osteosynthesis were used. At follow-up after a mean of 3.3 years, 15 of 25 patients had no pain. Most patients regained a nearly full range of motion in the adjacent joints and more than 90% of the contralateral grip strength. X-ray signs of degenerative arthritis in the metacarpohamate joint were observed in 10 of 25 patients. Pain was found to be directly correlated with the presence of degenerative changes.
