title: [Short-term results of modular extensively porous-coated revision stem in revision total hip arthroplasty].
abstract: OBJECTIVE
  To evaluate the short-term clinical and radiographic results of modular fully porous-coated stem in revision operation of total hip arthroplasty.
  
  
  METHODS
  From May 2001 to November 2002, ten cases with twelve hips received revision total hip arthroplasty using modular Profemur R with fully porous-coated stem. There were three males and seven females and the average age was 54.2 years (35 to approximately 71 years). The reasons for revision operation included aseptic loosing in eleven hips and septic loosing in one hip. All the patients were evaluated radiographically and clinically. Radiographic evaluation included the classification of bone loss, leg discrepancy, offset and antiversion before and after revision and bone in-growth postoperatively. Clinical evaluation were based on Harris score system.
  
  
  RESULTS
  The average follow-up period is 13.5 months (range: 6 to approximately 24 months). Leg discrepancy from more than 2 cm in six cases were restored to less than 1 cm postoperatively. Femoral offset, antiversion angle and neck-shaft angle were also restored to normal limitation. All the patients were allowed to full weight-bearing 3 to approximately 5 months later and pain relief occurred in all involved hips. At the last follow-up, bone in-growth occurred in eleven hips and solid fibrous fixation only in one case. Harris score was improved from a mean of 25 to 72. Complications mainly consisted of femoral shaft fracture in three cases but no infection or dislocation was found postoperatively.
  
  
  CONCLUSIONS
  Satisfactory results of short-term radiographic and clinical follow-up can be achieved using modular fully porous-coated stem for revision total hip arthroplasty.
