Abstract
BackgroundNonunion of hip fractures is not uncommon. Total hip arthroplasty is used to salvage cases of non union or secondary arthritis in these fractures. However, this option may not be available or may be difficult to achieve when infection has superseded the site of nonunion. The objective of this prospective study was to assess if a staged protocol of treatment yields good results in these difficult cases.Materials and methodsTwenty-seven consecutive patients who had deep hip infection with failed treatment of hip fractures (intracapsular in 16 cases and extracapsular in 11) were treated between June 2007 and September 2011. Twenty-six completed the planned two-stage hip arthroplasty and one case was lost after the first stage. The average age of the patients was 48.9 years (range 26–74 years) with an average follow up period of 44 months (30–72 months). Analysis was done using the paired t test where P < 0.05 was considered significant.ResultsInfection was controlled in all cases that completed the treatment protocol with no recurrence in all cases at the latest follow up. The Harris hip score of the patients improved significantly from 29 preoperatively to 85 at the latest follow up (P < 0.0001). Two patients had hip dislocation with displacement of the trochanteric fragment while three other patients had fibrous union of the trochanter.ConclusionsStaged Arthroplasty procedure to salvage infected non-union of hip fractures is successful in eradicating infection and regaining hip function.Level of evidence IV.

Summary
Both the intra and extra-capsular types, remains elusive to orthopaedic surgeons [1]. Total hip arthroplasty is used in many occasions to salvage cases of nonunion or secondary arthritis in these fractures [3] This option may not be available or may be difficult to achieve when infection has superseded the site of non union. Total hip arthroplasty is used to salvage cases of non union or secondary arthritis in these fractures The objective of this prospective study was to assess if a staged protocol of treatment yields good results in these difficult cases. Analysis was done using the paired t test where P \ 0.05 was considered significant
