A long-term review of shelf arthroplasty

Abstract

Shelf arthroplasty is briefly reviewed in historical perspective and the results in 45 hips (39 patients) which had undergone this procedure at the Royal Children's Hospital are presented. The majority of these patients were adolescents who had previously been treated for congenital dislocation or subluxation of the hip. The indications for operation and the operative technique are discussed. Clinical examination was carried out upon 33 of the 39 patients at an average of 11 years after operation. The results suggested that where pain had been an indication for operation almost 80 percent of the hips remained relatively free of symptoms at the time of follow-up and in those patients where acetabular dysplasia had been an indication, the coverage remained good and pain had not appeared. It is concluded that the shelf operation is useful for dealing with both pain and dysplasia in the adolescent.

Bosworth hip shelf arthroplasty in adult dysplastic hips: ten to twenty three year results

“…Despite good results published in the past [22][23][24][25], shelf operation is currently used mainly as a salvage procedure [9,21]. According to some authors, its main disadvantage is considered the fact that the bone graft does not ensure an adequate articulation for the femoral head cartilage [14].…”

“…Some studies evaluated outcomes in children, adolescents and adults together [10,12,[23][24][25][26][27]. Another problem is the indication of the shelf operation.…”

“…Another problem is the indication of the shelf operation. Evaluation of many groups is based primarily on the outcomes in subluxated or dislocated hips, less frequently in acetabular dysplasia [10,12,21,[23][24][25][26][27]. Some of these studies evaluated hips after septic arthritis, neuromuscular diseases, etc.…”

“…Migaud et al [11] evaluated 56 hips in 48 patients with a mean age of 32 years (range, 17-56) and a mean follow-up of 17 years (range, [15][16][17][18][19][20][21][22][23][24][25][26][27][28][29][30]. Pre-operative joint space narrowing was observed in 32 of 56 shelf arthroplasties.…”

Acetabular Augmentation by Residual Hip Dysplasia

“…SAA is therefore considered to be an adequate alternative to the redirectional and periarticular osteotomies of the acetabulum. No reports on the SAA treatment of hip dysplasia in adults have yet been published, but good outcomes have been reported with other augmentation techniques in adults (Courtois et al, 1987;Love et al, 1980;Migaud et al, 2004). The severity of preoperative arthrosis and the congruency have been identified as the main factors impairing survivorship in these patients (Fawzy et al, 2005).…”
