RADIOLOGICAL IMPROVEMENT FOLLOWING TECTOP LASTY PERFORMED ON ADVANCEDHIP SECONDARY OSTEOARTHRITIS (OA)

Tectoplasty was performed 10 times on adult dysplasic hips with advanc ed secondary OA for which femoral osteotomy could be considered. The 5 hips with pre-operative osteoarthritis staged IV according to De Mour gues scale and 3 of the 5 hips pre-operatively staged III displayed at maximal follow-up (on an average of 9.6 years), improvement of the ra diographic articular space. The other 2 hips showed a stabilization of the x-ray osteoarthritis. Clinical improvement with an average gain o f 2.5 points according to Merle d'Aubigne scale was always noted along with these improvements or these x-ray stabilizations.
