In this case report, a 60-years-old man is presented who had been operated on because of a osteoarthritis secondary to a femoral neck fracture in 1977. The interesting aspect of this case is that left hip was replaced with Judet type prosthesis, which survived for 30 years. This is one of the few prostheses which have not failed to stand the test of time and may still be encountered.

In September, 1971, the problem of loosening of methylmethacrylate cemented total hip arthroplasties moved Judet group to develop and study a model of a press fit total hip prosthesis without cement. The main objective of this prosthesis was to obtain a kind of alveolate and porous surface, whith cavities between 200 microns and 2 mm broad and about 1-2 mm deep, so that new formed bone fillig these cavities could be thick and strong enough to resist the pressure and stresses to which it could be submitted. The metal used was a cobat chrome molybdenum nickel alloy; the prosthesis was cast following a special procedure which produced the alveolate and porous surface. 

The prosthesis was composed of 2 components. The femoral stem had a quadriangular section which was strong at the top and thinner towards the inferior end. A fenestrated trapezoidal fin was attached to the stem which was implanted in the trochanter. A flat collar sat around the stem above the trapezoidal fin. The articular component had an articular socket made of High Density Polyethylene (H.D.P.) contained in a cup made of alveolate and porous metal. The polyethylene could be replaced without removing the cup.

Case Report :

We report a case of a man aged 60 who, in 1970, was involved in a car accident after which he reported fractures of the left femoral neck and left femoral diaphisis; he had undergone a operation of reduction and synthesis with intramedullary nail. After 7 years he developed a secondary osteoarthritis and in December 1977 he had hip arthroplasty. Left hip was replaced with Judet type prosthesis, CoCr head Æ 28 mm, medium neck and a cementless and screw-fixed cylindrical socket (Judet Special Cup) Æ 52 mm with an interchangeable PE insert (Fig. 1).

Since that time he had had no trouble with his hip. We have seen him in our Institute (G. Pini, Milan) in September 2007 for a medical inspection. On examination he had 70° of hip flexion with 10° of abduction, internal and external rotation. All movements were pain free.

Discussion :

Other very long-term results of hip replacement are rare. Joshi et al (1993) reported the 24-years survival of a Charnley-type prosthesis and Zaoussis and Patikas (1989) reported two McKee-type implants still insitu after 20 years. In fact, in the long search for effective hip arthroplasty, few prostheses have not failed to stand the test of time. One such is the Judet prosthesis, which may still be encountered.
