Purpose: The present study shows the long-term results of 24 patients with isolated posterior malleolar fractures between 1985 and 1990.

Methods: Outcome parameters used were (1) a functional outcome questionnaire (Olerud score), (2) physical examination (loaded dorsal range of motion [ROM]), (3) radiologic signs of instability (medial clear-space widening), (4) radiologic anatomic result (Cedell score), and (5) posttraumatic long-term damage (osteoarthritis).

Results: After a median of 20 years (range, 17-24 years), follow-up was achieved in 95% (n = 19) of living available patients. All patients were treated conservatively. The median Olerud score was 100 points, with 53% of the patients in the “excellent” result group. Excellent results were scored in 63% (loaded dorsal ROM), 32% (medial clear-space widening), 37% (osteoarthritis), and 47% (Cedell score). “Good” results were scored in 21% (Olerud score), 32% (loaded dorsal ROM), 68% (medial clear-space widening), 58% (osteoarthritis), and 37% (Cedell score). “Moderate” results were scored in 26% (Olerud score), 5% (loaded dorsal ROM), 5% (osteoarthritis), and 16% (Cedell score). Not 1 patient scored a “poor” result in any of the outcome parameters (Figure).

Conclusions: Conservative treatment of isolated posterior malleolar fractures resulted in good clinical and radiologic outcome in this series, with proof of little osteoarthritis at long-term follow-up.
