Acetabulum augmentation for Legg-Calvé-Perthes disease

Outcomes in Advanced Legg-Calvé-Perthes Disease Treated With the Staheli Procedure

“…In Huang's study, two patients had return of full ROM, and the remaining 12 had improvement in abduction and internal rotation [17]. Dimitriou et al reported improved ROM as well [11]. Five of our cases with considerable limitation of ROM and an incongruent hip with Classes 4 and 5 [14] had improved hip ROM at final follow-up.…”

“…Various salvage procedures used for LCPD in other studies have shown symptomatic improvement [2,8,11]. SAA is easier to perform and avoids secondary deformities [5,23,24].…”

“…Subluxation ratios in our study decreased from 1.6 preoperatively to 1.17 postoperatively. Dimitriou noted a decrease in the subluxation ratio [11] as did Huang, with a subluxation ratio that decreased from 1.7 to 1.2 [17]. The classification of Stulberg et al was 33.3% for Classes 1 and 2 (good) and 38.1% for Class 3 (fair) with the remainder in Classes 4 or 5.…”

“…Lateral displacement, flattening of the femoral head, and coxa magna may result in hinge abduction. The end result may be incongruity of the hip and decreased coverage of the femoral head [11]. In a long-term follow-up of 37 patients reported by McAndrew and Weinstein, 15 patients underwent hip arthroplasty because of pain and dysfunction.…”

The role of shelf acetabuloplasty in early and late stages of Perthes disease: A meta-analysis of observational studies

“…Twenty articles published between 1991 and 2011 (17 retrospective cohort studies [15][16][17][18][19][20][21][22][26][27][28][29][30][31][32][33][34] and three retrospective comparative studies [10,14,35]) were identified for the qualitative systematic review.…”
