Charnley Arthroplasty in Osteoarthritis Secondary to Congenital Dislocation or Subluxation of the Hip

Cemented Total Hip Arthroplasty With Subtrochanteric Osteotomy in Dysplastic Hips

“…During acetabular reconstruction of the dysplastic adult hip, it is acknowledged that the anatomic center of hip rotation should be restored [20,27,36], although the difficulties in identifying and preparing the true acetabulum and achieving stable fixation of the acetabular component are well described [7,10,13,16,28]. On the femoral side, there are further technical challenges, including excessive femoral neck anteversion resulting in a posterior position of the greater trochanter and chronic shortening of the surrounding soft tissue structures.…”

Total hip replacement for developmental dysplasia of the hip: How I do it

“…To achieve this, the main prerequisite is to restore the abductor mechanism. The rotation center should be seated near the anatomic position in both the coronal and sagittal planes (Cham- ley and Feagin 1973, Dunn and Hess 1976, Fredin and Unander-Scharin 1980, Mendes 1981, Hartofilakidis et al 1988, Linde et al 1988, Garvin et al 1991, Morscher 1995. The offset of the stems we use gives sufficient lever arm for the abductor muscles.…”

Femoral shortening in total arthroplasty for completely dislocated hips:3–7 year results in 25 cases

“…Some authors (Charnley andFeagin 1973, Coventry 1974) therefore believe that total hip replacement is contraindicated in these patients, while others prefer to place the cup in the false acetabulum (Jasty et al 1995). The position of the cup proximal to the center of the acetabulum will result in less lateral bony support, and loosening of acetabular components placed on the pelvic wall present a major problem (Linde et al 1988). Placing of the cup at the site of the true acetabulum in dislocated hips secures the acetabular component in a position where bone cover is maximum, without the need for extensive structural bone grafting.…”

“…Placing of the cup at the site of the true acetabulum in dislocated hips secures the acetabular component in a position where bone cover is maximum, without the need for extensive structural bone grafting. The resultant force on the hip will be optimal, and this improves the function of the gluteal muscles and facilitates leg-lengthening (Dunn and Hess 1976, Harley and Wilkinson 1987, Hartofilakidis et al 1988, Linde et al 1988.…”

“…Total replacement in adults with severe hip pain secondary to complete dislocation presents a technical challenge, and complications and failures are more frequent than after native arthoplasties (Dunn and Hess 1976, Crowe et al 1979, Hartofilakidis et al 1988, Linde et al 1988, Jasty et al 1995. Successful management demands anatomic reduction without excessive compression force across the joint.…”
