Background
In this work, we present relatively long-term results of femoral head fractures with a specific focus on Pipkin type I fractures.
Methods
Fifty-nine femoral head fractures were treated according to modified Pipkin’s classification as follows: type I, small fragment distal to the fovea centralis (FC); type II, large fragment distal to the FC; type III, large fragment proximal to the FC; type IV, comminuted fracture. There were 15 cases of type I, 28 of type II, 9 of type III, and 7 of type IV fractures. Conservative treatment with skeletal traction was performed in 4 type II cases, excision of the fragment in 15 type I and 10 type II cases, fixation of the fragment in 14 type II and all 9 type III cases, and total hip replacement in all 7 type IV cases. The overall clinical and radiographic outcomes were evaluated using previously published criteria, focusing on the results in Pipkin type I fractures with relatively large fragments.
Results
Based on Epstein criteria, in type II fractures, excellent or good clinical results were seen in 6 of 10 patients (60.0 %) treated by excision of the fragment and 12 of 14 patients (85.7 %) treated by internal fixation (p = 0.05). Also, excellent or good radiologic results were seen in 4 of 10 (40.0 %) patients treated by excision of the fragment and 12 of 14 (85.7 %) patients treated by internal fixation (p = 0.03).
Conclusions
Even in Pipkin type I fractures, if the fragment is large (modified Pipkin type II), early reduction and internal fixation can produce good results.
