[Hip osteo-arthritis sequelas in infant: classification and therapeutics indications]

ABSTRACT

From a test of classification with regard to osteo-articular lesions and their functional effect, the authors precise the therapeutic indication through 56 cases of hip osteo-arthritis sequelas in the infant. It's about a retrospective study based on 62 hips trated from 1976 to 1990. The group of increasing gravity has been individualized a first group of stable and mobile hips required remodeling a second group of stiff hips treated orthopeadically and a third group of dislocated hips who imposed abstention or artroplasty. The result has been appreciated on joint stability and the evolution of joint articular lesions. All hips of group I have preserved a good stability. In group II, the orthopedic treatment led towards the recovery of a modest mobility towards stiffness without articular fusion or towards surgical arthrodesis. In group III, only 2 good results have been preserved by anthroplasty seven years after. The analysis of observation in retrospect of seven years allowed to note that if the dislocation of the hip should occur it would be done in the first months that follow the stage of the arthritis. This notice led the authors to propose a classification based on the stability of the hip at the sequel stage. This classification allowed, in addition, to guide therapeutic indications
