[Results of anterior and posterior capsular approaches in bipolar hemiarthroplasty patients with femoral neck fractures].
BACKGROUND
We evaluated the functional status and postoperative complications of bipolar hemiarthroplasty patients with femoral neck fractures, which we operated using anterior and posterior approaches.


METHODS
Between November 2007 and February 2011, 224 patients were evaluated according to their surgical exposure type in two groups. The first group, which was approached anteriorly to the joint capsule, included 92 patients, and the second group, approached posteriorly, included 132 patients. The mean follow-up period for group 1 was 16.4 months and for group 2 was 18.9 months.


RESULTS
Harris hip score of group 1 was 81.7 and of group 2 was 79.2. In group 1, 19 patients had very good, 52 patients good, 15 patients moderate, and 6 patients insufficient results. In group 2, 29 patients had very good, 74 patients good, 21 patients moderate, and 8 patients insufficient results. Although we had higher hip dislocation and infection rates in group 2, there were no statistical differences between the two groups.


CONCLUSIONS
Surgical exposure type does not affect functional outcome in bipolar hip arthroplasty patients. Although statistically insignificant, we had higher hip dislocation and infection rates using the posterior approach in the selected femoral neck fracture patients. An anterior approach to the joint capsule appears to be more reliable.
