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.

Abstract Introduction: The objective of this study was 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).Patients and method: Thirteen patients (13 hips) with Crowe type IV DDH who underwent THA used modified trochanteric osteotomy between May 2013 and October 2019 were retrospectively analyzed. Mean follow-up was 5.2 ± 0.8 years (range, 4.9-6.1 years).Results: Mean Harris Hip Score (HHS) significantly (p < 0.05) improved from 30.7 ± 5.8 (range, 22-38) to 87.5 ± 3.6 (range, 83-93). The mean leg length discrepancy (LLD) was 53.4 ± 9.1 mm (range, 42.1-68.5 mm) preoperatively. The final LLD was 5.6 ± 2.4 mm (range, 2.4-9.1 mm). The mean leg length after surgery was 47.4 ± 10 mm (range, 33.6-67.2 mm). The average duration of bone union for greater trochanter (GT) was 2.5 ± 0.6 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 cementless cup is an effective treatment for Crowe type IV developmental dysplasia of the hip. It can rebuild complex biomechanics and biology of hip dysplasia without increasing complications.

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.

Abstract Background: The study assessed the correlation among the patients’ perception on leg length discrepancy (LLD) after total hip arthroplasty (THA) in patients with unilateral Crowe type IV developmental dysplasia of the hip (DDH) and the four methods of measuring the leg length in the full-length standing anteroposterior radiographs. Methods: 60 patients with unilateral Crowe type IV DDH were recruited in this retrospective study between January 2012 and January 2019. Four methods of measurement were used: (1) TD-TP: distance between the inferior aspect of teardrop and the midpoint of tibial plafond (TP). (2) CH-TP: distance between the center of femoral head or acetabular cup and the TP. (3) GT-TP: distance between the apex of greater trochanter and the TP. (4) FL + TL: the sum of femoral length and tibial length. Results: Association was found among the patients’ perception on LLD with difference in TD-TP (OR, 1.157), and the difference in FL + TL (OR, 1.166). The area under the curve of the difference in FL + TL and the difference TD-TP (0.704 and 0.679) was significantly higher than those of the difference in CH-TP and the difference in GT-TP (0.564 and 0.483). With the calculated threshold of LLD set at 9.0 mm, the sensitivity and specificity of the difference in TD-TP and the difference in FL + TL were 57.7%, 79.4% and 61.5%, 79.4%, respectively.Conclusion: Patients’ perception on LLD had good correlation and reliability on the difference of FL + TL and the difference of TD-TP.

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.

Objective: To evaluate the feasibility and accuracy of three-dimensional (3D)-printed individualised guiding templates in total hip arthroplasty (THA) for the treatment of developmental dysplasia of the hip (DDH). Methods: 12 hips in 12 patients with Crowe type IV DDH were treated with THA. A 3D digital model of the pelvis and lower limbs was reconstructed using the computed tomography data of the patients. Preoperative surgical simulations were performed to determine the most suitable surgical planning, including femoral osteotomy and prosthesis placement. Based on the ideal surgical planning, individualised guiding templates were designed by software, manufactured using a 3D printer, and used in acetabulum reconstruction and femoral osteotomy during surgery. Results: 12 patients were followed up for an average of 72.42 months (range 38–135 months). During surgery, the guiding template for each case was matched to the bony markers of the acetabulum and proximal femur. Preoperative and follow-up Harris hip scores were 34.2 ± 3.7 and 85.2 ± 4.2; leg length discrepancy, 51.5 ± 6.5 mm and 10.2 ± 1.5 mm; and visual analogue scale scores, 6.2 ± 0.8 and 1.3 ± 0.3, respectively, with statistical difference. Shortened deformity and claudication of the affected limb were obviously improved after surgery. However, 1 patient had artificial hip dislocation 2 weeks after surgery, and another patient had sciatic nerve traction injury, both of whom recovered after physical treatment. Conclusions: Preoperative surgical simulation and 3D-printed individualised guiding templates can fulfil surgeon-specific requirements for the treatment of Crowe type IV DDH. Accurate THA can be achieved using 3D-printed individualised templates, which provide a new personalised surgical plan for the precise positioning and orientation of acetabular reconstruction and femoral osteotomy.

Abstract Background Performing total hip arthroplasty (THA) in patients with Crowe IV developmental dysplasia of the hip (DDH) is technically challenging. Subtrochanteric shortening osteotomy is typically required for placing the acetabular component within the anatomic hip center. However, the outcomes of subtrochanteric osteotomy using cemented components are not widely reported. This study aimed to evaluate the outcomes of cemented stem THA with subtrochanteric femoral shortening and transverse derotational osteotomy in patients with Crowe IV DDH.Methods We retrospectively evaluated data of patients with Crowe IV DDH who underwent cemented stem THA with subtrochanteric femoral shortening and transverse derotational osteotomy between 2010 and 2018. Patients who underwent surgery at the hip joint were excluded. Data regarding pre- and postoperative clinical and radiological parameters were collected and reviewed.Results Among 14 patients included (14 hips), the mean age was 60.4 (range, 47–73) years. The mean Harris hip score improved from 40.7 to 87.7. The mean limb length discrepancy reduced from 52 mm to 12.7 mm. No neurologic deficits were noted. The mean osteotomy union time was 10.6 months. Delayed union and postoperative dislocation were observed in one and two patients, respectively. Cement leakage into the osteotomy gap was observed in one patient. No revisions were required. No signs of loosening or migration were observed. Conclusions Cemented stem THA combined with subtrochanteric femoral shortening and transverse derotational osteotomy is safe and effective for the treatment of patients with Crowe IV DDH. The cemented femoral component showed promising mid-term follow up results. However, cement leakage affects bone healing. Osteotomy and cementing should be performed meticulously.Trial Registration: Retrospectively registered
