What is the prognosis of these fractures?
Union rates with appropriate treatment are very high (~99%) and other than slight reduction in flexion and extension at the elbow, function is preserved. Unlike many other intra-articular fractures, olecranon fractures result in relatively little secondary osteoarthritic changes, probably on account of most fractures occurring though a relatively non-articular part of the trochlear groove.
Two pins and wire transfix the fracture through the olecranon process in good position. Fracture healing is well advanced with interval callus formation present. No joint effusion is noted.
