Abstract:
OBJECTIVETo observe the changes of proximal femoral geometry after femoral neck fracture treated with THA, analyze the existent of differences and their manifestation.
METHODSAll patients of femoral neck fracture (FNF) and osteonecrosis of femoral head (ONFH) were treated with THA by the same operating team from January to December of 2014, including 22 patients with FNF (11 males and 11 females,with age from 44 to 83 years old (means 66.18 ± 11.47) and 23 patients with ONFH (12 males and 11 females, with age from 19 to 68 years old (means 51.91 ± 11.76). After THA, height of femorals, offsets, osteotomy position and adjusting modes were measured and the statistic analysis was done.
RESULTSAfter THA, all patients were measured. Decreased femoral height, offsets and lower osteotomy positions were found in patients with FNF than those with ONFH, and 3 kinds of adjustments because of lower-positional osteotomy were found.
CONCLUSIONAfter THA, lower-positional osteotomy and decreased femoral offsets may occur on patients with FNF. The adjustments caused by lower-positional osteotomy may lead to negative results.
