Comparison of re-operation rates following primary and secondary hemiarthroplasty of the hip.

Primary arthroplasty or internal fixation are the most common ways of treating intracapsular femoral neck fractures, while arthroplasty is the preferred salvage treatment after failed internal fixation. A prospective registration of hip hemiarthroplasties between January 1998 and March 2002 identified 282 procedures for an acute femoral neck fracture and 149 procedures after failed internal fixation with two parallel screws. Chart review was performed after 19-74 months.
