“…Under normal conditions, all the cartilage of an apophasis' is completely ossified at the end of the growth period. After transposition to the joint, this process seems to be modified leaving the most superficial layers of the new articulating surface unossified, like what was seen when apophyseal cartilage was transplanted to joint defects by Benum P [11].…”

Septic arthritis of hip joint in children may lead to many complications; the study represents a female patient aged seven years with complete absence of femoral head and neck after previous history of septic arthritis the protocol of management as the following manner: debridement with traction, deepening acetabular osteotomy and subtrochanteric osteotomy combined with trochanteric epiphysis transposition into deepened acetabulum. The result was good in relation to hip movement after period of follow-up, the only residual problem was limb shorting which managed later on.

“…A 6-year-old girl suffering from this condition was admitted to our department in 1985. Bearing in mind that apophyseal cartilage has the potential to develop into a kind of joint cartilage when transplanted to a joint ( Benum 1974 ), I transposed the apophysis of the greater trochanter into the acetabulum in an attempt to reconstruct the femoral head. Encouraged by the short-term result after this operation, and by medium-term results reported after similar operations ( Hunka et al 1982 , Dal Monte et al 1984 ), I later used this method in 3 other children.…”

Background and purpose Total necrosis of the femoral head after infection in children during their first months of life gives a dislocated hip with severe leg shortening. A new femoral head can be achieved with subtrochanteric osteotomy and transposition of the apophysis of the greater trochanter into the acetabulum. Previous reports have dealt with short-term results (up to 12 years). Here I present some results of this procedure 15–24 years after operation.Patients and methods 4 children aged 1–6 years with complete necrosis of the femoral head were operated on with transposition of the greater trochanter. Secondary shelf plasty was performed later in 1 child, distal femoral epiphysiodesis in another, and femoral bone lengthening in 1 child. The mean follow-up period was 19 (15–24) years.Results A new femoral head developed in all hips. 2 of them had a spherical head with a good acetabular cover, and without any osteoarthritis except for slight reduction of cartilage height. These hips were painless, with a mobility that allowed good walking function after 16 and 24 years, respectively. In the other 2 patients, in which there was a severe acetabular dysplasia at the primary operation, the new femoral head was somewhat flattened; painful osteoarthritis led to hip replacement 15 and 21 years after trochanter arthroplasty. Even these patients had a relatively good walking function until the last couple of years before hip replacement. Maximum leg length discrepancy was 7 cm.Interpretation Trochanter arthroplasty with subtrochanteric osteotomy in total femoral head necrosis after septic arthritis in children may give satisfactory long-term results provided adequate acetabular cover is obtained. Although the method cannot provide a normal hip, it can contribute to less length discrepancy, less pain, improved gait, and more favorable conditions for later hip replacement.

“…In terms of recovery of normal joint function, however, use of an osteochondral graft is more satisfactory. In 1975, Benum 5 carried out an osteochondral graft to the load-bearing area of the medial femoral condyle of puppies. The graft was found to have been accepted satisfactorily after 14 months.…”
