Abstract Background Whether satisfactory clinical and radiological outcomes of total hip arthroplasty (THA) with subtrochanteric shortening osteotomy (SSO) in high hip dislocation after childhood pyogenic infection can be achieved as in Crowe IV developmental dysplasia of the hip (DDH) remains unclear. Methods Between September 2009 and December 2016, 151 primary THAs performed at our institution using similar SSO technique and prosthetic design were retrospectively reviewed. After excluding patients who met exclusion criteria, 29 patients were identified as high dislocation (Crowe IV) after childhood infection (HDACI) and 107 as Crowe IV developmental dysplasia of the hip (DDH). Propensity score matching was used to select 29 Crowe IV DDH patients as a control group for the HDACI group with comparable preoperative conditions. Clinical and radiological outcomes and complication were compared and analyzed. The mean follow-up duration of the 2 groups was 5.0 years. Results The mean Harris hip score (HHS) and the mean score in range of motion (ROM) domain of the modified Merle d’Aubigné-Postel (MAP) were 84.6 and 4.5 in the HDACI group, compared with 88.3 and 4.9 in the DDH group; there was significant difference between the 2 groups in these parameters (P = 0.015 and 0.035, respectively). Meanwhile, in the HDACI group, the median time of osteotomy union was 4 months and osteotomy nonunion rate was 3%; no significant difference was detected in the median time of osteotomy union and osteotomy nonunion rate between the 2 groups (P = 0.388 and 1.000, respectively). And no significant difference was found in the rate of complications between two groups. Conclusions HDACI patients who received THA combined with SSO could achieve similar satisfactory results as DDH patients in Crowe type IV. The fixation technique of autogenous cortical bone struts had a positive influence on osteotomy healing of SSO in this specific setting.

Abstract Background: The purpose of this study was to explore that how to equalize the leg length in total hip arthroplasty (THA) with shortening subtrochanteric osteotomy (SSTO) or not for unilateral Crowe type IV developmental dysplasia of the hip (DDH) through the evaluation of the postoperative full-length anteroposterior radiographs. Methods: The postoperative radiographs of 60 patients with unilateral Crowe type IV DDH from July 2012 to May 2019 were retrospectively reviewed. These data included leg length, femoral length, height of center of rotation (COR) of hip, height of greater trochanter, and depth of the sleeve or cone. Patients with leg length discrepancy (LLD) < 10 mm were defined as the non-LLD group. Results: In the non LLD group (26 patients of SSTO and 22 of non-SSTO), the femoral length both SSTO and non-SSTO groups were significantly shorter on operated side, compared with the contralateral side, and the mean discrepancy in SSTO group was approximately equal to the mean length of SSTO. The mean height of COR of hip on operated sides both SSTO and non-SSTO groups were 13.2 mm, and the contralateral sides were 15.2 mm and 15.5 mm, respectively. The depth of the sleeve or cone between SSTO and non-SSTO groups were 21.7 mm and 30.6 mm, respectively. The depth of the sleeve or cone in SSTO group was negatively correlated with the length of SSTO. The height of the greater trochanter of the operated and contralateral sides were 5.3 mm and 16.6 mm in SSTO group, and those in the non-SSTO group were 13.2 mm and 17.2 mm. Conclusions: SSTO leaded to femoral shortening on the operated side for patients with unilateral Crowe type IV DDH. The position of sleeve or cone should be close to the apex of greater trochanter to compensate the lengh of SSTO.

Infection at the pseudoacetabulum in a patient with a high hip dislocation has not been reported previously in the English literature. We report a case of total hip arthroplasty in a 28-year-old female who presented to us with hip pain following debridement of the infected pseudojoint in a case of neglected developmental dysplasia of the hip. The infection was treated with thorough debridement and drainage. However, even after achieving complete infection control, this patient complained of disabling right hip joint pain. Total hip arthroplasty with subtrochanteric osteotomy was performed to relieve the pain and improve gait. After surgery, the patient's symptoms were relieved. We consider that in this case of acute pseudojoint infection simple arthrotomy and debridement combined with irrigation and drainage provide effective treatment. But muscle weakness and more increased joint laxity can cause hip pain even after infection control. So total hip arthroplasty is likely to be necessary after the infection has been controlled in a patient with a highly dislocated hip.

Abstract Background: High hip center technique is still controversial about the survivorship of prothesis and postoperative complications. We aimed to show the utility of high hip center technique used in patients with Crowe II-III developmental dysplasia of the hip at the midterm follow-up and evaluated the clinical and radiographic results between different heights of hip center.Methods: We retrospectively evaluated 69 patients (85 hips) with Crowe II-III dysplasia who underwent a high hip center cementless total hip arthroplasty at a mean follow up of 8.9 years (range, 6.0-14.1years). The patients were divided into two groups according to the height of hip center, respectively group A (≥22mm and <28mm) and group B (≥28mm). Radiographic, functional and survivorship outcomes were evaluated.Results: The mean location of the hip center from the inter-teardrop was 25.1mm vertically and 30.0mm horizontally in the group A, and 33.1mm vertically and 31.4mm horizontally in the group B. There were no statistically significant differences between two groups in postoperative femoral offset, abductor lever arm, leg length discrepancy and cup inclination. At the final follow up, the mean WOMAC and Harris hip score were significantly improved in both groups. Of the 85 hips, 7 hips (8.2%) showed a positive Trendelenburg sign. Additionally, 6 patients (8.7%) presented with a limp. No significant differences were shown regarding the Harris hip score, WOMAC score, Trendelenburg sign and limp between two groups. The Kaplan-Meier implants survivorship rates at the final follow-up for all-causes revisions in the group A and group B were similar (96.7% [95% confidence interval, 90.5%-100%] and 96.2% [95% confidence interval, 89.0%-100%], respectively).Conclusions: The high hip center technique is a valuable alternative to achieve excellent midterm results for Crowe II-III developmental dysplasia of the hip. Further, we reported good results and could not demonstrate any significant differences in outcomes or survivorship between the groups with differing degrees of HHC in our study, however the relatively small sample size must be considered and larger comparative studies are required to confirm the value of high hip center technique.

Previous studies have shown better clinical outcomes after total hip arthroplasty (THA) compared to hemiarthroplasty (HA) for displaced femoral neck fracture. However, few studies have focused on the surgical risks of the two procedures. Therefore, we investigated the perioperative complications of HA and THA in femoral neck fracture, using a large nationwide inpatient database. A total of 286,269 patients (281,140 patients with HA and 5129 with THA) with a mean age of 81.7 were enrolled and HA and THA patients were matched by a propensity score to adjust for patient and hospital characteristics. Patients in a matched cohort were analyzed to compare complications and mortality. The systemic complication rate was not significantly different after a propensity score matching of 4967 pairs of patients. However, the incidence of both hip dislocation and revision surgery was more frequent in the THA group (Risk difference (RD), 2.74; 95% Confidence interval (CI), 2.21–3.27; p < 0.001; RD, 2.82; 95% CI, 2.27–3.37; p < 0.001, respectively). There was no significant difference in 30 day in-hospital mortality among the two groups. The risk of dislocation and reoperation was higher for THA than for HA in elderly patients with a femoral neck fracture in this retrospective study using a nationwide database.

Abstract Background This study aimed to explore mid-term clinical results of cementless total hip arthroplasty (THA) with modified trochanteric osteotomy in Crowe type IV developmental dysplasia of the hip (DDH). Methods Thirteen patients (13 hips) with Crowe type IV DDH who underwent THA with modified trochanteric osteotomy between May 2013 and October 2015 were retrospectively analyzed. The mean follow-up duration was 5.2 years (range, 4.9–6.1 years). Results The mean Harris Hip Score (HHS) significantly (p < 0.05) improved from 30.7 (range, 22–38) to 87.5 (range, 83–93). The mean leg length discrepancy (LLD) was 53.4 mm (range, 42.1–68.5 mm) preoperatively. The final LLD was 5.6 mm (range, 2.4–9.1 mm; p < 0.05). The mean leg length after surgery was 47.4 mm (range, 33.6–67.2 mm) and the femur shortening distance was 43.8 mm (range, 31.2–53.4 mm). The average duration of bone union for the greater trochanter (GT) was 2.5 months (range, 1.5–3.6 months). There was no infection, GT non-union, or loosening (septic or aseptic) of the stem or cup in any case. Conclusions THA with modified trochanteric osteotomy with a cementless cup is an effective treatment for Crowe type IV DDH. It can rebuild complex biomechanics and biology of hip dysplasia without increasing complications.

Objective This study was performed to document the clinical and radiographic results of consecutive patients with Crowe IV developmental dysplasia of the hip (DDH) treated by cementless total hip arthroplasty (THA) using an S-ROM femoral component with shortening derotational subtrochanteric osteotomy. Methods Twenty-three hips of 21 patients with Crowe IV DDH were treated by cementless THA combined with shortening derotational subtrochanteric osteotomy from January 2005 to January 2011. The mean preoperative modified Harris hip score (mHHS) and University of California, Los Angeles (UCLA) activity score were 40.7 and 4.2, respectively. Results The mean follow-up was 105 months. The mean mHHS and UCLA score improved to 87.0 and 9.1, respectively, at the latest follow-up. Nine of the 23 hips had a negative Trendelenburg sign. One of the 23 hips was outside the Lewinnek acetabular cup inclination safe range, and 3 of the 23 hips were outside the Lewinnek acetabular cup anteversion safe range. The probability of prosthesis survival was 100% at 5 years and 91.3% at 10 years. Conclusion Patients with Crowe IV DDH can be treated by cementless THA combined with shortening derotational subtrochanteric osteotomy. This method can greatly improve hip joint function and relieve pain without significant complications.

Dysplasia Of The Hip

Background A high rate of postoperative dislocation in total hip arthroplasty (THA) for Crowe IV developmental dysplasia of the hip (DDH) has been reported, 1 of the main reasons being higher true acetabular anteversion. If the cup is fixed with normal anteversion, the anterior rim will be excessively exposed, which reduces the contact areas of the cup and bone, affects prosthesis stability, and leads to iliopsoas tendinitis and persistent hip pain after THA. The aim of this study was to demonstrate that when cup anteversion is larger, adjusting femoral anteversion to bring the combined anteversion (CA) into the “safe zone” might prevent dislocation. Methods After having fixed the cup in the acetabulum according to the patients’ native acetabular anteversion, we shortened and rotated the proximal femur to reduce femoral anteversion, adjusting the CA into the “safe zone”. The Harris Hip Score (HHS) was used to evaluate hip joint function. Computerised tomography scanning was used to measure the anteversion angles. Results All patients were followed up without any dislocation. Preoperative and 12 months after surgery, the mean HHS were 43.3 ± 2.6 (38-47) and 88.1 ± 3.3 (78-92) respectively. Pre- and post-operation, the mean CA angles were 88.6° ± 9.4° (80.3°-119.4°) and 49.2° ± 2.6° (43.4°-54.4°) respectively. The bone healing time of femoral osteotomy ranged from 4 to 14 months, with a mean time of 7.5 months. Conclusions This CA technique in THA for Crowe IV DDH can effectively prevent postoperative dislocation and provide good hip function.
