BackgroundTotal hip arthroplasty (THA) performed for developmental dysplasia of the hip is a technically difficult procedure with a high complication rate, especially in the presence of completely dislocated hips. This study aimed to evaluate at least 10 years of follow-up results of cementless, ceramic-on-ceramic (CoC) THA performed with transverse subtrochanteric osteotomy in Crowe type IV hips.MethodsWe retrospectively reviewed 50 patients’ 67 hips that underwent CoC, cementless THA with transverse subtrochanteric osteotomy between 2008 and 2011. Clinical and radiological data of the hips were examined. Clinical results were evaluated using the Harris Hip Score and the Western Ontario and McMaster Universities Osteoarthritis Index.ResultsThe mean Harris Hip Score improved from 22.9 ± 9.9 preoperatively to 94.1 ± 8.1 at the final follow-up (P < 0.001). The median Western Ontario and McMaster Universities Osteoarthritis Index score improved from 72 (interquartile range: 17) preoperatively to 2 (interquartile range: 17) postoperatively (P < 0.001). The preoperative mean leg length discrepancy was improved from 4.9 ± 1 cm to 1.5 ± 1 cm in unilateral cases at the last follow-up (P < 0.001). Revision surgery was required because of nonunion in two patients, prosthetic infection in one patient, and aseptic femoral loosening in the other patient. The overall ten-year survival rate was 94% for femoral stems and 98.5% for acetabular components as per Kaplan-Meier survival analysis.ConclusionTransverse subtrochanteric shortening osteotomy combined with using cementless acetabular and femoral components with a CoC bearing surface promises successful clinical results and high prosthesis survival in the treatment of Crowe IV hips at long-term follow-up. 相似文献

Background
When surgeons reconstruct hips with a high dislocation related to severe developmental dysplasia of the hip (DDH) in total hip arthroplasty (THA), archiving long-term stable implant fixation and improving patient function and satisfaction remain challenging. The purpose of this study was to evaluate the 10-year outcomes of transverse subtrochanteric shortening osteotomy in cementless, modular THA in Crowe type IV-Hartofilakidis type III DDH.Methods
We reviewed 62 patients (76 hips) who underwent cementless THA with transverse subtrochanteric shortening osteotomy from 2002-2010. There were 49 women and 13 men with a mean age of 38.8 years, all of whom had Crowe type IV DDH. Mean follow-up period was 10 years. The acetabular cup was implanted in placement of the anatomical hip center in all hips.Results
The mean Harris Hip Score significantly improved from 38.8 points to 86.1 points. Similarly, modified Merle d'Aubigne and Postel Hip Score, Hip dysfunction and Osteoarthritis Outcome Score, and SF-12 also significantly improved. The mean limb length discrepancy was reduced from 4.3 cm to 1.0 cm. At mean follow-up of 10 years, there were 3 cases of postoperative dislocation, 2 cases of transient nerve palsy, 1 case of nonunion, and 4 cases of intraoperative fracture. Revision surgery was performed in 2 patients due to isolated loosening of acetabular component and femoral stem, respectively.Conclusion
Our data demonstrated that the cementless, modular THA combined with transverse subtrochanteric shortening osteotomy was an effective and reliable technique with high rates of successful fixation of the implants and satisfactory clinical outcomes. 相似文献3.

BackgroundThe direct anterior approach (DAA) is increasingly used for total hip arthroplasty (THA). Although the DAA can reduce pain, recovery time, and dislocations in nondysplastic hips, few studies report its results in patients with severe dysplasia. We aimed to evaluate outcomes of primary THA through the DAA with cup placement at the true acetabulum in hips with severe dysplasia.MethodsWe retrospectively evaluated 23 consecutive patients (29 hips) who underwent THA by DAA for osteoarthritis secondary to Crowe III-IV dysplasia. Surgical procedures were performed on a traction table, and the acetabular cup was placed in the true acetabulum. Patients were assessed clinically (complications, modified Harris Hip Score, Western Ontario and McMaster Universities Osteoarthritis Index, Oxford Hip Score) and radiographically (radiolucencies, subsidence, leg length discrepancies, cup inclination, and cup coverage) at a minimum of 2 years.ResultsOne patient (2 hips) died with original implants (at 13 and 14 years), 3 patients (3 hips) were revised due to wear-induced loosening (at 14, 16, and 18 years), and there were no dislocations or infections. The remaining 19 patients (24 hips) were assessed at 8.4 ± 4.7 years (range 2-20); 2 patients (2 hips) had complications that required reoperation without implant removal. The modified Harris Hip Score improved from 32 ± 9 to 94 ± 7, Western Ontario and McMaster Universities Osteoarthritis Index from 46 ± 18 to 90 ± 7, and Oxford Hip Score was 56 ± 4. Patients were very satisfied (90%) or satisfied (10%). Limb length discrepancy was 2.5 ± 9.0 mm.ConclusionTHA through the DAA with cup placement at the true acetabulum provides satisfactory mid to long-term clinical and radiographic outcomes compared to other approaches for hips with severe dysplasia.Level of EvidenceLevel IV, retrospective cohort study. 相似文献

BackgroundThe reconstruction of high dislocation related to developmental dysplasia of the hip (DDH) remains challenging for joint surgeons. The aim of this study is to evaluate the rate of union, the revision rate, functional scores, and complications in patients with Crowe IV DDH treated with total hip arthroplasty, transverse subtrochanteric shortening osteotomy, and modular stem in an average 10-year follow-up.MethodsTwenty-eight patients (33 hips) with Crowe IV DDH who were operated on between 2008 and 2013 were followed. All patients underwent uncemented total hip arthroplasty with transverse subtrochanteric shortening osteotomy and anatomical acetabular cup implantation. The mean age was 36.6 years, and the mean follow-up period was 121 months. Clinical and radiological outcomes were evaluated.ResultsThe mean Harris Hip Score significantly improved from 47.0 preoperatively to 89.6 postoperatively. The mean limb length discrepancy was significantly reduced from 3.8 to 0.8 cm. The mean osteotomy union time was 6.8 months. At the mean follow-up of 121 months, there were 3 cases of postoperative dislocation, 2 cases of intraoperative fracture, and 1 case of posterior tibial venous thrombosis. No revision occurred, and no signs of component loosening or migration were observed at the last follow-up.ConclusionCrowe IV DDH patients treated with transverse subtrochanteric shortening osteotomy, modular stem, and anatomic acetabular component insertion can have satisfactory and reliable 10-year clinical outcomes. 相似文献

BackgroundThe aim of this study is to assess treatment of Crowe type IV hip dysplasia with the Wagner cone femoral stem combined with transverse subtrochanteric shortening osteotomy and augmenting the osteotomy site using the intercalary segment as a strut autograft.MethodsOne hundred twenty-seven hips of 91 patients diagnosed with Crowe type IV hip dysplasia and treated with total hip arthroplasty using the Wagner cone stem combined with transverse subtrochanteric shortening osteotomy were retrospectively evaluated by clinical and radiographic outcomes as well as complications.ResultsThe mean follow-up was 8.4 years. The Harris Hip Score and the Western Ontario and McMaster University Osteoarthritis Index scores were significantly improved postoperatively (P = .000). Intraoperative femoral cracks were observed in 70 hips (55.1%) and all femurs healed smoothly. Femoral cracks did not have a significant effect on clinical outcomes, except for heterotopic ossifications (P = .032). The probability of 10-year survivorship of the components free of revision for any reasons as end point was 94.5%; when only the femoral components were considered the survivorship was of 96.9%.ConclusionTransverse subtrochanteric shortening and augmenting the osteotomy site using the intercalary segment of bone resected from the shortened femur with the Wagner cone stem is an effective and reliable technique in the management of total hip arthroplasty in Crowe type IV hip dysplasia. Stable and firm placing of the femoral component which leads to an increased frequency of intraoperative femoral cracks does not have an unfavorable effect on clinical and radiological outcomes. 相似文献

BackgroundThe aim of this study is to compare clinical results of Crowe type III-IV developmental dysplasia of the hip (DDH) patients who underwent total hip arthroplasty with either trochanteric slide osteotomy (TSO) or subtrochanteric shortening osteotomy (SSO).MethodsThe patients who underwent cementless total hip arthroplasty with femoral shortening osteotomy due to Crowe type III/IV DDH between 2004 and 2014 and completed at least 5 years of follow-up were retrospectively analyzed. The patients were grouped according to the type of shortening osteotomy as either TSO or SSO. Preoperative and postoperative clinical evaluation included Harris Hip Score, Visual Analogue Scale pain, leg length discrepancy, and the presence of Trendelenburg sign. The clinical outcome measures and complication rates were compared in terms of osteotomy type.ResultsThe TSO group consisted of 34 patients (43 hips) and the SSO group consisted of 40 patients (51 hips). The SSO group (96.1%) had a slightly higher 5-year survival of the implant compared to TSO (93%) without statistical significance (P = .18). No significant difference was detected between the groups in terms of clinical outcomes. Complication rates did not significantly differ between the groups except for the lack of bony union which was significantly higher in TSO (P = .006) but this difference did not transform into clinical significance since 5 of 6 patients who did not have a bony union in the TSO group were symptom-free with a fibrous union.ConclusionTSO and SSO provide similar clinical outcomes at mid-term follow-up in the management of Crowe III-IV DDH by cementless total hip arthroplasty. Both techniques can be used safely depending on the surgeon’s preference.Level of EvidenceLevel III, Therapeutic, Case-control study. 相似文献

BackgroundThis study aimed to determine the differences in survivorship, clinical function, and complications among patients who have Hartofilakidis Type C1 or C2 developmental dysplasia of the hips and underwent total hip arthroplasty (THA) with cementless implants.MethodsThis retrospective study identified 84 Hartofilakidis Type C hips that underwent THA between 2002 and 2011 with a minimum 10-year follow-up (mean, 13 years, range, 10 to 19 years). Survivorship, latest Harris Hip Scores and satisfaction levels, radiographic outcomes (eg, implant stability, rate and length of subtrochanteric shortening transverse osteotomy, leg-length discrepancy, cup position, and orientation), as well as complications (eg, dislocation, periprosthetic fracture, periprosthetic joint infection) were compared to analyze the differences between Hartofilakidis C1 and C2 hips.ResultsBetween C1 and C2 hips, no difference existed in the 15-year cumulative Kaplan-Meier survivorship, with the endpoint defined as any reoperation (93.1 versus 90.8%), aseptic loosening combined with periprosthetic joint infection (93.1 versus 96.2%), or aseptic loosening (94.8 versus 96.2%), latest Harris Hip Score (87.1 versus 86.1%), vertical (6.1 versus 6.0 mm) and horizontal (11.5 versus 10.3 mm) distance to the anatomic center of rotation, postoperative leg length discrepancy (11.2 versus 15.5 mm), dislocation (5.2 versus 11.5%), stem aseptic loosening (6.9 versus 7.7%), periprosthetic fracture (3.4 versus 7.7%), and intraoperative femoral fracture (32.8 versus 23.1%). However, Type C2 hips demonstrated more severe preoperative leg length discrepancy (66.9 versus 42.5 mm) and required a higher percentage of subtrochanteric shortening transverse osteotomies (84.6 versus 36.2%) that were longer (33.7 versus 26.47 mm) than the Type C1 hips.ConclusionWith cementless cups positioned near the anatomic acetabular center and cementless stems combined with subtrochanteric shortening transverse osteotomies, THAs for the Hartofilakidis Type C1 and C2 hips demonstrated similar survivorship, clinical function, and complications. 相似文献

BackgroundTotal hip arthroplasty (THA) with subtrochanteric shortening osteotomy (SSO) is performed to manage hips with high dislocations. We compared outcomes of THA with SSO in patients with high hip dislocation resulting from childhood septic arthritis and Crowe IV developmental dysplasia of the hip (DDH).MethodsWe reviewed 60 THAs with SSO performed between May 1996 and December 2013. Thirty-one cases were classified as sequelae of childhood infection and 29 as DDH. Twenty-five hips were selected for each group after the propensity score was matched with preoperative demographics and leg length discrepancy (LLD). Clinical scores, complication and reoperation rates, radiographic results, and survivorships were compared. The mean duration of follow-up was 12.3 (range 5-22) years.ResultsThe average correction in LLD was 2.5 cm for childhood infection and 3.6 cm for DDH (P = .002). The infection group received more transfusions (mean 3.3 vs 2.0 units, P = .002), required more time for union of osteotomy site (mean 6.8 vs 5.2 months, P = .042), and reported lower Harris Hip Score (mean 85.1 vs 91.3, P = .017). Reoperations were performed in 11 (44%) previously infected hips and 3 (12%) DDHs (P = .012). Kaplan-Meier survivorship with an endpoint of revision for any reason was lower in the infection group (83.6%) than in the DDH group (100%) at 10 years (log rank, P = .040).ConclusionTHA with SSO in high hip dislocation secondary to childhood septic arthritis demonstrated less favorable clinical outcomes with increased risks of complication, compared with those performed in Crowe IV DDH with similar degree of chronic dislocation. 相似文献

ObjectivePerforming subtrochanteric osteotomy with cemented components in patients with Crowe IV developmental dysplasia of the hip (DDH) is technically challenging and not widely reported. This study aimed to evaluate the mid‐term outcomes of cemented stem total hip arthroplasty (THA) with subtrochanteric femoral shortening and transverse derotational osteotomy in patients with Crowe IV DDH.MethodsData collected from patients with Crowe IV DDH who underwent cemented stem THA with subtrochanteric femoral shortening and transverse derotational osteotomy between 2010 and 2018 were retrospectively evaluated. The cemented Lubinus SP II femoral component and the cementless CombiCup acetabular component were used together in all cases. These data, including Harris hip scores, limb length discrepancy (LLD), severity of limp, Trendelenburg test, bone union, length of the resected femur, limb lengthening, level of the osteotomy site, and length bridging the osteotomy site, as well as complications, were analyzed. A paired Student t‐test was used to analyze continuous variables, categorical data were compared using Fisher''s exact probability test, and correlation analysis was performed using Spearman''s rank correlation coefficient.ResultsAmong 14 included patients (10 females and four males), the mean age was 60.4 years (range, 47–73). The mean follow‐up period was 49.1 months, and no patient was lost to follow‐up. The mean Harris hip score improved from 40.7 to 87.7. The mean LLD decreased from 52 to 12.7 mm. The mean length of the excised femoral segment was 38.4 mm, and the mean length of limb lengthening was 27.1 mm. The mean distance between the osteotomy site and the lesser trochanter was 21.1 mm after surgery. The mean length of the femoral stem bridging the osteotomy site was 97.6 mm. Finally, the mean osteotomy union time was 10.6 months. No statistically significant correlation was found between the osteotomy union time and these factors. No neurological deficits were noted. Delayed union was observed in one patient, and postoperative dislocation was observed in two patients. Cement leakage into the osteotomy gap was observed in one patient, however, no revisions were required, and no signs of loosening or migration were observed.ConclusionsCemented stem THA combined with subtrochanteric femoral shortening and transverse derotational osteotomy is safe and effective in treating patients with Crowe IV DDH. Rather than leading to nonunion, cement leakage may negatively affect bone healing. 相似文献

BackgroundTotal hip arthroplasty (THA) of patients with a proximal femoral deformity is technically demanding. This deformity poses the risk of femoral fracture or perforation; stem malposition; and failed stem fixation. To insert a femoral stem in neutral position with a good fit, we removed the greater trochanter in case of a varus deformity, and the lesser trochanter in case of valgus deformity, while performing THA. We aimed to evaluate stem position, implant stability, clinical results, and radiological changes after THAs using this technique.MethodsFifteen patients (17 hips; 11 varus hips and 6 valgus hips) underwent cementless THA using the trochanteric osteotomy technique in one institution. We evaluated procedure-specific complications: intraoperative femoral fracture, stem malposition, weakness of the abductor power and limp. Modified Harris Hip Score, radiological changes, and the stability of stems were assessed at a mean of 7.1 years of follow-up (range 2.0-15.5).ResultsFemoral fracture occurred during the insertion of the stem in 4 hips. All stems were aligned in neutral position. At the latest follow-up, the mean power of the abductor was 4.3 (range 3-5). Eleven patients had slight limp and 4 patients had moderate limp. All stems had bone-ingrown stability and no stem was revised. The mean modified Harris Hip Score improved from 50 points at the preoperative evaluation to 81 points at the final follow-up.ConclusionThe trochanteric excision enabled neutral insertion of cementless stem in patients with varus/valgus deformity of the proximal femur, and THA using this technique rendered favorable results. 相似文献

Background
A number of methods for reduction in high hip dislocation in total hip arthroplasty (THA) are time-consuming and laborious, and require great surgical skills. This study aimed to introduce a new reduction technique to achieve rapid, safe, and easy reduction in high hip dislocation.Methods
We retrospectively reviewed 74 THA patients (82 hips; 44 women, 30 men) with severe hip dysplasia who underwent direct leverage using a Hohmann retractor into the anatomical acetabulum without femoral shortening osteotomy between September 2007 and January 2014. Forty-nine hips were classified as Crowe III and 33 hips were classified as Crowe IV. The mean follow-up period was 5.1 years (range 2-8).Results
Mean Harris Hip Score increased from 42.1 (range 24-71) before surgery to 89.9 (range 76-100) at final follow-up examination. The legs were lengthened by a mean of 3.0 cm (range 1.1-5.5) and 2.5 cm (range 1.1-3.5) in Crowe III hips and 3.6 cm (range 1.9-5.5) in Crowe IV hips postoperatively. The average leg-length discrepancy at the final follow-up examination was 0.4 cm (standard deviation 0.5 cm). One greater trochanteric fracture occurred during the hip reduction process. One patient developed femoral nerve palsies and recovered completely at 3 weeks postoperatively.Conclusion
Direct leverage using the Hohmann retractor for the reduction in high hip dislocation in THA without femoral shortening osteotomy is simple, safe, and effective. 相似文献14.

Introduction Inferior survival of cemented total hip arthroplasty has been reported after previous femoral osteotomy. The purpose of this study was to evaluate the long-term survival of uncemented stems after femoral osteotomy.Materials and methods Forty-eight hips in 45 patients had undergone conversion THA for a failed intertrochanteric osteotomy of the hip after a mean of 12 years (2–33 years). Mean time of follow-up was 11 years (5–15 years).Results At follow-up, two patients (three hips) had died, and one patient (one hip) was not located. Three patients (three hips) underwent femoral revision—one for infection and two for aseptic loosening of the stem. Survival of the stem was 94% at 10 years, and survival with femoral revision for aseptic loosening as an end point was 96%. The median Harris Hip Score at follow-up was 80 points. Radiolucent lines in Gruen zones 1 and 7 were present in 14 and 18% of hips, respectively. Radiolucencies in other zones were not detected. There was no radiographic evidence of femoral osteolysis, stress-shielding or loosening.Conclusion The results with this type of uncemented tapered titanium femoral component after proximal femoral osteotomy are encouraging and compare to those achieved in patients with regular femoral anatomy. 相似文献

BackgroundShort-stem femoral implants (SSFIs) promote the preservation of bone in the femoral neck, reduce soft tissue disruption, and facilitate minimally invasive surgical techniques. The purpose of this study was to report the revision rate, complication rate, patient satisfaction, patient-reported outcomes, and radiographic outcomes of patients who underwent total hip arthroplasty (THA) with the Alteon Neck Preserving Femoral Stem (ANPS).MethodsA prospectively maintained database was reviewed which analyzed 92 THAs between the years 2016 and 2018. Patient-reported outcomes, patient satisfaction, complication rates, and radiographic outcomes were assessed at 2-5 years postoperatively.ResultsThe final cohort consisted of 63 hips. Five patients (7.9%) underwent revision surgery and 2 (3.2%) had other complications not requiring revision. Survivorship when considering only the femoral component was 93.7% at an average of 41.4 months of follow-up. The average postoperative Oxford Hip Score (41.5 ± 8.3) and Harris Hip Score (77.9 ± 16.6) demonstrated significant improvement among our nonrevised patients, respectively (P < .001). Radiographs demonstrated spot welding in 56% of arthroplasties most commonly in Gruen Zones 2, 3, and 13 and that femur radiolucencies were visualized in 58% predominantly along the distal aspect of the stem. Radiographic femoral component subsidence was present in 9.7% of patients.ConclusionThe ANPS may be less reliable than previously reported. Our cohort’s revision rate was unacceptably high with 6.3% requiring revision surgery for femoral component loosening in less than 5 years. Surgeons should consider the challenges and prohibitive failure rate associated with SSFIs before routine usage in THA. 相似文献

BackgroundTotal Hip Arthroplasty remains the standard treatment protocol for patients with neglected traumatic dislocations of the hip with arthritis. A total hip arthroplasty needs to be frequently combined with a subtrochanteric shortening femoral osteotomy to aid in the reduction of the hip joint in such cases. Still long-term stable implant fixation, rigid construct, and favorable functional outcome remain a challenge. In respect to subtrochanteric shortening osteotomy, various techniques have been described in the literature, including the step-cut, double chevron, transverse, and oblique osteotomies. Out of these types, a subtrochanteric step-cut osteotomy provides a better rotational stability and a larger surface of contact to aid in union. As there is a paucity in the literature regarding the step-cut osteotomy for traumatic dislocations of the hip, we designed this study to evaluate the outcomes of this procedure.MethodsWe prospectively evaluated 24 patients with neglected traumatic dislocations of the hip, who underwent total hip arthroplasty with a step-cut subtrochanteric shortening osteotomy using a long modular stem within a span of 4 years. The indications were severe pain and difficulty in walking and performing activities of daily living. Patients fulfilling the inclusion criteria were evaluated in terms of Harris Hip Score, leg length discrepancy, neurological status, union of the osteotomy, and implant stability.ResultsThe mean Harris Hip Score significantly improved from 33.4 preoperatively to 89.2 postoperatively at the latest follow-up. At the final follow-up, all patients showed union at the osteotomy site and there were no cases of implant loosening or instability. No neurological complications were reported.ConclusionsTotal hip arthroplasty combined with a step-cut subtrochanteric femoral shortening osteotomy in patients with neglected dislocations of the hip was associated with good functional outcome and higher success rates in terms of stable implant fixation and union at the site of osteotomy. 相似文献

全髋关节置换术治疗Crowe Ⅳ型髋关节发育不良患者及围手术期并发症分析 总被引:1,自引:1,他引:0
目的:探讨人工全髋关节置换术治疗Crowe Ⅳ型成人髋关节发育不良的疗效及围手术期并发症。方法:2000年3月至2010年3月,对19例(23髋)Crowe Ⅳ型成人髋关节发育不良患者进行人工全髋关节置换术,其中男5例,女14例;年龄41~72岁,平均61.3岁。髋臼侧采用小臼杯结合髋臼内陷技术安置臼杯假体,股骨侧采用粗隆下短缩截骨放置股骨假体。采用Harris评分评价术后髋关节功能。结果:所有患者获随访,时间1~8年,平均4.2年,术后X线片显示髋臼假体均位于真臼内,无髋臼假体松动。股骨侧截骨处均骨性愈合。Harris评分由术前平均(34.0±6.9)分提高至末次随访的(85.0±7.5)分。发生围手术期并发症11例,包括股骨劈裂骨折3例,神经并发症3例,截骨延迟愈合2例,术后脱位3例。结论:采用小臼杯、假体内陷技术、股骨短缩截骨对Crowe Ⅳ型DDH患者行全髋关节置换可以重建关节功能,恢复下肢长度,早期疗效满意,但并发症发生率高。后期疗效有待进一步观察。 相似文献
