“…Hybrid or cemented THA or the first generation of cementless THA in patients with high dislocation has been associated with high complication and revision rates [6,8,10,13,14,19,23,26,27]. The rate of osteolysis has been reported between 13% and 58.5% with an average followup from 5.5 to 10.8 years [21,22,24,[27][28][29][30].…”

To ascertain whether THA in patients with high dislocation after childhood sepsis would relieve pain and improve function, we assessed the rate of postoperative infection, improvement in Harris hip and WOMAC scores, and improvement in range of motion after the THA in 62 patients (62 hips) with high dislocation (Crowe Type 4) after childhood sepsis. The revision rate and the incidence of complications also were assessed. The mean age of the patients was 47.5 years. The minimum followup was 13 years (mean, 15.2 years; range, 13-17 years). One patient had persistent infection. The mean preoperative Harris hip score of 55 points improved to 89 points at the final followup, and the mean preoperative WOMAC score of 65 points improved to 42 points. The mean combined preoperative arc of range of motion of 197°improved to 275°. Four cups (6%) and three stems (5%) were revised. Complications developed in nine hips (15%), but the rate of infection was low. Improved surgical technique and design of components provided favorable results for total hip replacement performed for complications of childhood sepsis in these young and active patients.

“…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.…”

“…dysplasia, subluxation, and dislocation. Hartofilakidis et al [7] adapted such a concept for adults (Table 1) relying on radiographic and morphologic criteria validated during THA to describe acetabular and femoral involvement. That classification included three types of increasing severity: dysplasia (Type A), low dislocation (Type B), and high dislocation (Type C) (Fig.…”

Three different types of congenital hip disease in adults have been distinguished based upon the position of the femoral head relative to the acetabulum and the underlying pathoanatomy of the joint: (1) dysplasia; (2) low dislocation; and (3) high dislocation. To facilitate classification of borderline or ambiguous cases, we studied the morphologic variations of low and high dislocation as observed on the radiographs of 101 hips with low and 74 hips with high dislocation. In low dislocation, 54 hips (53.5%) had extended coverage of the true acetabulum (Type B1) and 47 hips (46.5%) had limited coverage (Type B2). Among the cases with high dislocation, a false acetabulum with an adjacent femoral head occurred in 46 hips (62.2%) (Type C1), and the femoral head was floating within the gluteal muscles in 28 hips (37.8%) (Type C2). The kappa value for interobserver agreement between two raters who made radiographic measurements was 0.963, and for intraobserver agreement between the two evaluations of the same observer it was 0.946 and 0.971, respectively. The two types of low and high dislocation were associated with high intra-and interobserver agreement. Whether these distinctions have clinical utility requires further validation.
