Total Hip Arthroplasty for Congenital Hip Disease

Lesser trochanteric osteotomy in total hip arthroplasty for treating CROWE type IV developmental dysplasia of hip

“…Lesser trochanteric osteotomy for femoral shortening has no fracture line that requires support and protection for union, and is also easy to perform. Therefore, we do not favour shortening of the femoral diaphysis as the first choice, as has been suggested by others [11].…”

“…Subtrochanteric osteotomy either transverse, oblique chevron or T-shaped has been well documented with good clinical results [4][5][6][7][8][9], but nonunion and complexity in performance remain the major concerns in the procedure [4,10]. Progressive osteotomy at the femoral neck with greater trochanteric osteotomy [11] and distal femur osteotomy were also reported in previous studies [12].…”

The Morphologic Variations of Low and High Hip Dislocation

“…The classification of Hartofilakidis et al [8] is based on the morphology of the deformed acetabulum as observed on anteroposterior pelvis radiographs. It has been confirmed by comparing radiographic observations with intraoperative findings [6][7][8]. The implications of the current refinement are: (1) to increase the reliability of the original classification; (2) to identify differences in treatment choices and complications associated with the subtypes; and (3) to help control for confounding preoperative variables in assessing results.…”

“…Hartofilakidis et al [6][7][8] classification described three types of DDH, namely dysplasia and low and high dislocation. Our clinical experience suggested types B and C could be divided in two subtypes each due to distinct morphological variations found at surgery.…”

“…Several classification systems have been proposed to describe the extent of hip involvement [2,4,[6][7][8][9]. Chung [1] described in infants and children dysplastic hips without subluxation, hips with subluxation, and hips with frank dislocation in 1981.…”
