RECURRENT DISLOCATION OF TOTAL HIP PROSTHESIS DONE IN ANKYLOSING SPONDYLITIS WITH SPINOPELVIC MALROTATION- A CASE REPORT

PRAVIN .

Abstract


Abstract : The purpose of this study was to evaluate the results of total hip arthroplasties with special  regard to angle of cup position in patients with bilaterally ankylosed hips.thirty five year old male, an  engineer was diagnosed to have              ankylosing spondylitis with bilateral chronic arthritis hip,with  sacroilitis. patient was treated with uncemented total hip  arthroplasty. Postoperatively patient had  recurrent dislocation of the prosthesis twice and we concluded that the altered pelvic biomechanics in  ankylosing spondylitis inturn modifies the version and inclination of prosthetic component causing  recurrent dislocation of hip.
