BackgroundThe problem of failed acetabulum fracture fixation is increasing due to increased incidence of high-velocity injury and a large number of patients are being operated on in the past few years. Limited evidence is available regarding results of Total hip arthroplasty (THA) in patients with failed acetabulum fracture fixation surgery. We assessed the clinical, radiological and postoperative complications. Besides this, we also evaluated functional outcome and quality of life following THA in failed open reduction and internal fixation of acetabular fractures. MethodThe current retrospective study was performed at the tertiary center from 2015 to 2020. Eighteen patients of failed acetabulum fracture fixation surgery (14 males and 4 females) were included with a mean follow-up period of 2.4 years. Postero-lateral approach was done in all cases. Clinico-radiological outcome, functional outcomes were recorded according to Harris Hip score (HHS) and quality of life was assessed by using the 12-Item Short Form Health Survey (SF-12) score. Postoperative complications were also assessed. ResultsThe age of patients ranged from 20 years to 68 years with a mean age of 44.7 years. 16 of the patients (88.9%) had a united acetabular fracture while 2 of them (11.1%) presented with un-united acetabular fracture. The THA implant was found to be stable in all 18 cases. The Harris Hip score of the study ranged from 82 to 95 with a mean of 89.72 ± 4.24 while the SF-12 score ranged from 40.0 to 49.4 with a mean of 44.29 ± 2.95. Out of 18 cases, 11 (61.1%) returned with excellent outcomes while the rest 7 (38.9%) returned with good outcomes as per Harris Hips score criteria. The correlation and regression analysis shows between HHS and SF-12 was positive and statistically significant (r = 0.592, p = 0.010 ).ConclusionTHA in patients with failed acetabulum fracture fixation surgery provides a reliable option with satisfactory outcomes along with a better quality of life. 相似文献

BackgroundOptimum management for the elderly acetabular fracture remains undefined. Open reduction and internal fixation (ORIF) in this population does not allow early weight-bearing and has an increased risk of failure. This study aimed to define outcomes of total hip arthroplasty (THA) in the setting of an acetabular fracture and compared delayed THA after acetabular ORIF (ORIF delayed THA) and acute fixation and THA (ORIF acute THA). MethodsAll acetabular fractures in patients older than 60 years who underwent ORIF between 2007 and 2018 were reviewed (n = 85). Of those, 14 underwent ORIF only initially and required subsequent THA (ORIF delayed THA). Twelve underwent an acute THA at the time of the ORIF (ORIF acute THA). The ORIF acute THA group was older (81 ± 7 vs 76 ± 8; P < .01) but had no other demographic- or injury-related differences compared with the ORIF delayed THA group. Outcome measures included operative time, length of stay, complications, radiographic assessments (component orientation, leg-length discrepancy, heterotopic ossification), and functional outcomes using the Oxford Hip Score (OHS). ResultsOperative time ( P = .1) and length of stay ( P = .5) for the initial surgical procedure (ORIF only or ORIF THA) were not different between groups. Four patients had a complication and required further surgeries; no difference was seen between groups. Radiographic assessments were similar between groups. The ORIF acute THA group had a significantly better OHS (40.1 ± 3.9) than the ORIF delayed THA group (33.6 ± 8.5) ( P = .03). ConclusionIn elderly acetabulum fractures, ORIF acute THA compared favorably (a better OHS, single operation/hospital visit, equivalent complications) with ORIF delayed THA. We would thus recommend that in patients with risk factors for failure requiring delayed THA (eg, dome or roof impaction) that ORIF acute THA be strongly considered. 相似文献

BackgroundThe optimal management of elderly patients with displaced acetabular fractures remains controversial. This paper aims to summarize the clinical results of open reduction and internal fixation (ORIF) and the possible factors influencing them. MethodsRadiographic and clinical data on 52 elderly patients with displaced acetabular fractures that were treated by ORIF between May 2000 and May 2008 were retrospectively analysed. Data, such as fracture type (Letournel's classification system), quality of reduction, clinical outcomes (Harris hip score and modified Merle d’Aubigne-Postel score), and radiological outcomes (Matta score), were evaluated. ResultsGood to excellent clinical and radiological outcomes were recorded in 43 (82.7%) and 37 patients (71.2%), respectively. Acetabular fractures without radiographic features, such as quadrilateral plate fracture, Gull sign, posterior dislocation of hip, posterior wall marginal impaction, comminuted posterior wall fracture, and femoral head injury, can still achieve good to excellent outcomes. However, patients with the abovementioned radiographic features tend to achieve fair or poor outcomes. When an acetabular fracture with the aforementioned features, except for femoral head injury, can achieve and maintain anatomic reduction until complete fracture healing, the difference between fractures with and without the radiographic features is no longer significant. The results indicate that the outcomes are more affected by reduction rather than radiographic features. ConclusionORIF may be suggested for displaced acetabular fractures in the elderly. Good to excellent outcomes and a high degree of patient satisfaction can be achieved in majority of the patients. We recommend ORIF as the preferred treatment for displaced acetabular fractures without the abovementioned radiographic features. Level of evidenceTherapeutic level IV. 相似文献

ObjectiveTo evaluate the clinical results of surgical resection of severe heterotopic ossification (HO) after the open reduction and internal fixation (ORIF) of acetabular fractures. MethodsA retrospective chart review was performed between October 2005 and November 2010 on patients undergoing severe HO resection following an acetabular fracture ORIF. Our primary outcome was functional status evaluated by the Harris hip score (HSS). HO resection and hip release was performed using a Kocher–Langenbeck approach in all cases, and a combined radiation and indomethacin regimen was used to prevent HO recurrence. Plain radiographs were also used to evaluate the hip joint for arthritic changes and HO recurrence. ResultsA total of 18 patients (17 males and 1 female) were included in our study analysis. The mean patient age was 36.8 (range: 22–54 years old) when HO resection surgery was performed. The mean time interval between acetabular fracture ORIF and HO resection was 9.9 months (range: 3–30 months): it was within 6 months in 7 patients, 6–12 months in 8 patients, and >12 months in 3 patients.The HO was graded as Brooker grade III in 8 patients and grade IV in 10 patients. The mean time interval between HO resection and the latest follow-up was 4.5 years (range: 2.1–7.8 years). The mean Harris hip score (HHS) was 84.5 (range: 38–100), with a clinical outcome rating of excellent in 9 patients, good in 3 patients, fair in 4 patients, and poor in 2 patients (good and excellent rating accounted for 66.7%). The mean hip joint motion arc was 194° (range: 90–260°).Complications included one intraoperative femoral neck fracture, 1 sciatic nerve injury, 2 femoral head avascular necrosis, and 6 mild HO recurrences (33.3%). There was 28.6% recurrence if HO resection was within 6 months and 36.4% if >6 months. There were no cases of severe HO recurrence, wound infections, deep vein thrombosis, or pulmonary embolism. ConclusionThe early surgical resection of severe HO after an acetabular fracture ORIF can provide satisfactory results, however the complication rate is relatively high. 相似文献

Total hip arthroplasty (THA) outcomes for posttraumatic arthritis after acetabular fracture have yielded inferior results compared to primary nontraumatic THA. Recently, improved results have been demonstrated using cementless acetabular reconstruction. Thirty-two patients underwent THA for posttraumatic arthritis after acetabular fracture; 24 were treated with open reduction internal fixation, and 8 were managed conservatively. Time from fracture to THA was 36 months (6-227 months). Average follow-up was 4.7 years (2.0-9.7 years). Harris Hip score increased from 28 (0-56) to 82 points (20-100). Six patients required revision. Five-year survival with revision, loosening, dislocation, or infection as an end point was 79%. Survival for aseptic acetabular loosening was 97%. Revision surgery correlated with nonanatomic restoration of the hip center and a history of infection (P < .05). Despite obvious challenges, advances in fracture management and cementless acetabular fixation in THA demonstrate improved results for posttraumatic arthritis following acetabular fracture. 相似文献

BackgroundThe increasing number of THAs in younger patients will inevitably result in an increase of revision procedures. However, there is little evidence about the outcome of revision procedures in this patient group. Therefore, we updated a previous study conducted 5 years ago about the outcome of revision procedures in patients younger than 55 years. Questions/purposesWe sought to provide a concise update on the previously reported (1) long-term failure rate as defined by repeat revision, (2) clinical outcome as defined by the Oxford Hip score and the Harris Hip score, and (3) radiographic outcome of cemented revision THA performed with impaction bone grafting on both the acetabular and femoral sides in one surgery in patients younger than 55 years old. MethodsBetween 1991 and 2007, we performed 86 complete THA revisions in patients younger than 55 years. In 38% (33 of 86) of revisions, bone impaction grafting was used on both the acetabular and femoral side because of acetabular and femoral bone stock loss. Mean age at time of revision was 46 ± 8 years. No patient was lost to follow-up, but six patients died during follow-up, including three since 2015. Still, the hips of all 33 patients were included in analysis at a mean of 17 ± 5 years. Failure was calculated using competing risk analysis. For clinical outcome, we assessed the Harris Hip score and the Oxford Hip score from our longitudinally maintained institutional database. Radiographic analysis was performed to evaluate radiographic loosening, defined as radiolucencies ≥ 2 mm in all zones or ≥ 5 mm migration for both components. The acetabular component was also considered loose with tilting ≥ 5° ResultsThe 15-year failure rate of revision THA was 27% (95% CI 13 to 44) for re-revision of any component for any reason and 10% (95% CI 3 to 25) for re-revision of any component for aseptic loosening. The mean Harris Hip score increased from 55 ± 18 preoperatively to 74 ± 22 at latest follow-up. Eight cups were considered radiographically loose, seven of which were re-revised. No stems were considered radiographically loose. Failure rate with endpoint radiographic loosening at 15 years was 23% (95% CI 10 to 39). ConclusionWe found that impaction bone grafting with a cemented cup and a cemented stem is a valuable biological revision technique that results in a stable and durable solution, after one or even multiple previous revision THAs. Although current implants may prove sufficient in most cases, they do not promote bone stock preservation. We believe that in young patients with bone stock loss, impaction bone grafting can be used as long as the defect can be contained adequately with a metal mesh and viable bone bed is available for revascularization.

Objective: To compare the clinical effects between closed reduction and internal fixation (CRIF) and total hip arthroplasty (THA) for displaced femoral neck fracture. Methods: In this prospective randomized study, 285 patients aged above 65 years with hip fractures (Garden III or IV) were included from January 2001 to December 2005. The cases were randomly allocated to either the CRIF group or THA group. Patients with pathological fractures (bone tumors or metabolic bone disease), preoperative avascular necrosis of the femoral head, osteoarthritis, rheumatoid arthritis, hemiplegia, long-term bed rest and complications affecting hip functions were excluded. Results: During the had significantly higher 5-year follow-up, CRIF group rates of complication in hipjoint, general complication and reoperation than THA group (38.3% vs. 12.7%, P〈0.01; 45.3% vs. 21.7%, P〈0.01; 33.6% vs. 10.2%, P〈0.05 respectively). There was no difference in mortality between the two groups. Postoperative function of the hip joint in THA group recovered favorably with higher Harris scores. Conclusion: For displaced fractures of the femoral neck in elderly patients, THA can achieve a lower rate of complication and reoperation, as well as better postoperative recovery of hip joint function compared with CRIF. 相似文献

IntroductionPatient reported outcome scores may be the preferred method to assess clinical results following acetabular fracture fixation. However, in current acetabular fracture research, there is a scarcity of studies using these scores and long-term follow-up is lacking. The aim of this study is to describe long-term patient reported outcomes following acetabular fracture surgery and to evaluate the association between reduction quality and these outcome measures. MethodsPatients who received operative fixation for acetabular fractures (1992–2012) were sent questionnaires (short musculoskeletal functional assessment (SMFA) function index and short form (SF)-12), which was returned by 106 patients (22%) (mean age 51 years, 74% male). Mean follow-up was 11.3 years and hip survivorship 78%. Reduction quality was assessed on postoperative CT or plain pelvic radiography (PXR) (3 patients). Reductions were graded as adequate (CT: <1 mm step and <5 mm gap/PXR: ≤3 mm displacement) or inadequate (CT: ≥1 mm step and/or ≥5 mm gap/PXR: >3 mm displacement). Outcome scores between native hip versus total hip arthroplasty (THA) and adequate versus inadequate reduction groups were compared and association between reduction quality and hip survivorship was determined. Subgroup analysis was performed in older patients (≥50 years). ResultsPatients with native hips reported overall superior relevant outcome scores (SMFA function index (p = 0.047), mobility (p = 0.048) and SF-12 physical component (p = 0.008)) compared to THA patients. Hip survivorship was associated with adequate reductions (p = 0.019). In the native hip group, an adequate reduction was also associated with lower (better) clinical scores (exceeding the minimal clinical important difference) (MCID) specifically for SMFA function index (p = 0.117) and mobility (p = 0.022). In elderly patients, the native hip versus THA group had similar outcomes, and adequate reductions were associated with hip survivorship as well as superior clinical scores (at least exceeding the MCID) in those who retained their native hip. ConclusionAt long-term follow-up, acetabular fracture surgery is associated with excellent patient reported outcomes. Patients who retain their native hip have overall superior relevant (SMFA and SF-12) function scores compared to those who convert to THA. Adequate reductions (on CT) were associated with both hip survivorship and superior outcome scores in patients who retain their hip. 相似文献

BackgroundAcetabular fractures often require surgical intervention for fracture fixation and can result in premature osteoarthritis of the hip joint. This study hypothesized that total hip arthroplasty (THA) in patients with a prior acetabular fracture who had undergone open reduction and internal fixation (ORIF) is associated with a higher rate of subsequent periprosthetic joint infection (PJI). MethodsAbout 72 patients with a history of acetabular fracture that required ORIF, undergoing conversion THA between 2000 and 2017 at our institution, were matched based on age, gender, body mass index, Charlson comorbidity index, and date of surgery in a 1:3 ratio with 215 patients receiving primary THA. The mean follow-up for the conversion THA cohort was 2.9 years (range, 1-12.15) and 3.06 years (range, 1-12.96) for the primary THA. ResultsPatients with a previous acetabular fracture, compared with the primary THA patients, had longer operative times, greater operative blood loss, and an increased need for allogeneic blood transfusion (26.4% vs 4.7%). Most notably, PJI rate was significantly higher in acetabular fracture group at 6.9% compared with 0.5% in the control group. Complications, such as aseptic revision, venous thromboembolism, and mortality, were similar between both groups. ConclusionThe present study demonstrates that conversion THA in patients with prior ORIF of acetabular fractures is associated with higher complication rate, in particular PJI, and less optimal outcome compared with patients undergoing primary THA. The latter findings compel us to seek and implement specific strategies that aim to reduce the risk of subsequent PJI in these patients. 相似文献

IntroductionAcetabular fracture subtypes are associated with varying rates of subsequent conversion total hip arthroplasty (THA) after open reduction internal fixation (ORIF) with transverse posterior wall (TPW) patterns having a higher risk for early conversion. Conversion THA is fraught with complications including increased rates of revision and periprosthetic joint infections (PJI). We aimed to determine if TPW pattern is associated with higher rates of readmissions and complications including PJI after conversion compared to other subtypes. MethodsWe retrospectively reviewed 1,938 acetabular fractures treated with ORIF at our institution from 2005 to 2019, of which 170 underwent conversion that met inclusion criteria, including 80 TPW fracture pattern. Conversion THA outcomes were compared by initial fracture pattern. There was no difference between the TPW and other fracture patterns in age, BMI, comorbidities, surgical variables, length of stay, ICU stay, discharge disposition, or hospital acquired complications related to their initial ORIF procedure. Multivariable analysis was performed to identify independent risk factors for PJI at both 90-days and 1-year after conversion. ResultsTPW fracture had higher risk of PJI after conversion THA at 1-year (16.3% vs 5.6%, p = 0.027). Multivariable analysis revealed TPW independently carried increased risk of 90-day (OR 4.89; 95% CI 1.16–20.52; p = 0.03) and 1-year PJI (OR 6.51; 95% CI 1.56–27.16; p = 0.01) compared to the other acetabular fracture patterns. There was no difference between the fracture cohorts in 90-day or 1-year mechanical complications including dislocation, periprosthetic fracture and revision THA for aseptic etiologies, or 90-day all-cause readmission after the conversion procedure. ConclusionAlthough conversion THA after acetabular ORIF carry high rates of PJI overall, TPW fractures are associated with increased risk for PJI after conversion compared to other fracture patterns at 1-year follow-up. Novel management/treatment of these patients either at the time of ORIF and/or conversion THA procedure are needed to reduce PJI rates.

BackgroundOsteopetrosis is an inherited bone disease associated with high risk of osteoarthritis and fracture non-union, which can lead to total hip arthroplasty (THA). Bone quality and morphology are altered in these patients, and there are limited data on results of THA in these patients. The goals of this study were to describe implant survivorship, clinical outcomes, radiographic results, and complications in patients with osteopetrosis undergoing primary THA. MethodsWe identified 7 patients (9 hips) with osteopetrosis who underwent primary THA between 1970 and 2017 utilizing our total joint registry. The mean age at index THA was 48 years and included two males and five females. The mean follow-up was 8 years. ResultsThe 10-year survivorship free from any revision or implant removal was 89%, with 1 revision and 1 resection arthroplasty secondary to periprosthetic femoral fractures. The 10-year survivorship free from any reoperation was 42%, with 4 additional reoperations (2 ORIFs for periprosthetic femoral fractures, 1 sciatic nerve palsy lysis of adhesions, 1 hematoma evacuation). Harris hip scores significantly increased at 5 years ( P = .04). Five hips had an intraoperative acetabular fracture, and 1 had an intraoperative femur fracture. All postoperative femoral fractures occurred in patients with intramedullary diameter less than 5 mm at a level 10 cm distal to the lesser trochanter. ConclusionPrimary THA in patients with osteopetrosis is associated with good 10-year implant survivorship (89%), but a very high reoperation (58%) and periprosthetic femoral fracture rate (44%). Femoral fractures appear associated with smaller intramedullary diameters. 相似文献

Failed open reduction internal fixation (ORIF) of the proximal femur can render patients severely disabled. This study analyzed the short-term functional results and complications of total hip arthroplasty (THA) for complications of ORIF after hip fracture. A retrospective arthroplasty database review identified 36 patients treated with a THA for complications of ORIF of the hip. These patients were matched to a cohort of 36 patients who underwent primary unilateral THA for osteoarthritis. Study results indicate that THA for failed ORIF of the hip is a successful procedure despite concerns of increased intraoperative difficulty and risk of fracture. 相似文献

BackgroundCementing a new liner into a secure, well-positioned metallic shell can be a less-invasive strategy in revision total hip arthroplasty (THA). This study aimed to report the mean 14-year outcomes of cementing highly cross-linked polyethylene (XLPE) liners into well-fixed acetabular shells in revision THAs. MethodsThis study reviewed a single-surgeon series of cementing XLPE liners into well-fixed acetabular components. Of the 52 hips (51 patients) evaluated, 48 hips (47 patients) that satisfied a minimum follow-up of 10 years were included. The Harris Hip score was used for clinical evaluation. Final hip radiographs were used to determine the extent of acetabular osteolysis and stability of the components. The mean age at index operation was 53 years (range, 32 to 72). The mean follow-up duration was 14 years (range, 10 to 18). ResultsThe mean Harris Hip score improved from 58 points (range, 23-81) preoperatively to 91 points (range, 45-100) at the final evaluation ( P < .001). A total of 3 acetabular rerevisions were performed, all for aseptic loosening of the outer shell. One postoperative dislocation occurred, but it was successfully treated with a closed reduction. Final radiographs showed a significant reduction in acetabular osteolysis ( P < .001). Implant survivorship free from any rerevision was 93.3% (95% confidence interval, 85.9-100%) at 14 years. ConclusionCementing an XLPE liner into a well-fixed acetabular shell in revision THA demonstrated excellent clinical and radiographic outcomes at a mean of 14 years postoperatively. This technique could be a safe and durable option in the absence of XLPE liners compatible with preimplanted shells. 相似文献

Background and purpose — Low-energy acetabulum fractures are uncommon, and mostly occur in elderly patients. Determining the optimal operative treatment for such fractures is challenging. Here we investigated whether acutely performed total hip arthroplasty plus posterior column plating (THA) reduced complications and reoperations compared with open reduction and internal fixation (ORIF) in elderly patients with acetabular fractures. Patients and methods — We retrospectively reviewed the records of 59 patients, > 55 years of age, with complex acetabular fractures, caused by low-energy trauma, treated between January 2008 and September 2017. Of these patients, 34 underwent acute THA, and 25 ORIF alone. Patient and implant survival were compared between groups using Kaplan–Meier survival analysis and Cox multiple regression. Functional outcomes assessed by Oxford Hip Score (OHS) were compared between the THA patients and those 9 ORIF patients who underwent secondary THA due to posttraumatic hip osteoarthritis (OA) during follow-up. Results — Overall patient survival was 90% (95% CI 82–98) at 12 months, and 64% (CI 47–81) at 5 years. Of 25 ORIF patients, 9 required secondary THA due to posttraumatic OA. Large fragments on the weight-bearing acetabular dome upon imaging predicted ORIF failure and secondary THA. The acute THA group and secondary THA group had similar 12-month OHS. Interpretation — Acute THA including a reinforcement ring resulted in fewer reoperations than ORIF alone in elderly patients with acetabular fractures. These findings support acute THA as first-line treatment for complex acetabular fractures in elderly patients. 相似文献

BackgroundFor patients who have a history of cerebrovascular accident (CVA) with neurological sequelae undergoing primary total hip arthroplasty (THA) and total knee arthroplasty (TKA), we sought to determine mortality rate, implant survivorship, complications, and clinical outcomes. MethodsOur total joint registry identified CVA sequelae patients undergoing primary THA (n = 42 with 25 on affected hip) and TKA (n = 56 with 34 on affected knee). Patients were 1:2 matched based upon age, sex, body mass index, and surgical year to a non-CVA cohort. Mortality and implant survivorship were evaluated via Kaplan-Meier methods. Clinical outcomes were assessed via Harris Hip scores or Knee Society scores . Mean follow-up was 5 years (range, 2-12). ResultsFor CVA sequelae and non-CVA patients, respectively, the 5-year patient survivorship was 69 versus 89% after THA (HR = 2.5; P = .006) and 56 versus 90% after TKA (HR = 2.4, P = .003). No significant difference was noted between groups in implant survivorship free from any reoperation after THA ( P > .2) and TKA ( P > .6). Postoperative CVA occurred at an equal rate in CVA sequelae and non-CVA patients after TKA (1.8%); none after THA in either group. The magnitude of change in Harris Hip scores ( P = .7) and Knee Society scores ( P = .7) were similar for CVA sequelae and non-CVA patients. ConclusionComplications, including the risk of postoperative CVA, implant survivorship, and outcome score improvement are similar for CVA sequelae and non-CVA patients. A 2.5-fold increased risk of death at a mean of 5 years after primary THA or TKA exist for CVA sequelae patients. 相似文献

BackgroundSurgical hip dislocation has been described as an excellent method for reduction and fixation of acetabular fractures. It allows a 360-degree access to the acetabulum and acetabular dome. However, reproducibility of this technique is still a concern. The primary outcome of this study was to investigate the short term functional and radiological outcome with the use of surgical hip dislocation in acetabular fractures. The secondary outcome was to describe different indications and methods of reduction using this technique. MethodsThis is a retrospective consecutive case series for the use of surgical hip dislocation in acetabular fractures. Between July 2013 and February 2017, we used this technique to manage 36 cases of acetabular fractures. Two patients were lost to follow up leaving 34 patients eligible for the study. All surgeries were done by a 5-years and a 10-years’ experience surgeons in pelvic and acetabular trauma surgeries. Through Gibson approach, we used the technique of surgical hip dislocation as described by the Bernese group. Different methods of fracture reduction were used. Intraoperative grading of cartilage injury was done using Disler's grading system. Postoperative fracture reduction was evaluated using the criteria described by Matta. Clinical evaluation was done using the modified Merle d'Aubigne ? and Postel system. ResultsThe mean intra-operative blood loss was about 700 ± 35.4 ml. The mean units of blood transfused were 1 ± 0.1 unit. The mean surgical time was 135 ± 11.7 minutes.Anatomical reduction was achieved in 27 patients (79.4%). At a mean of 30 ± 16.8 months (median = 26 and IQR 22) follow up, the functional score was excellent in 5 (14.7 %), very good in 8 (23.5%), good in 9 (26.5%), fair in 2 (5.8%), and poor in 10 (29.4%) patients. Four patients (11.7%) developed AVN at a mean of 8 months postoperatively. Conversion to THA was done in 5 patients (14,7%). Trochanteric osteotomy showed osseous healing in all cases. No patient developed nerve injury or infection. One patient developed severe (grade III) heterotopic ossification. ConclusionsBesides the indications of surgical hip dislocation mentioned before as reduction of the anterior column in T and Transverse fractures, associated femoral head fractures, intraarticular fragments, and labral injuries, it can be used in other indications as entrapped posterior wall, roof impaction, pure impaction injuries and cranial extension of the posterior wall fractures. The technique is reproducible; however, the learning curve is steep and needs to be performed by experienced acetabular trauma surgeons. 相似文献

目的探讨全髋关节置换术(THA)治疗成人髋臼骨折术后继发髋部深部感染的近期临床疗效。方法回顾性分析2009年8月至2012年12月采用THA手术治疗8例成人髋臼骨折术后继发髋部深部感染的临床资料,男5例,女3例;年龄38-51岁,平均45岁。前柱骨折1例,后柱并后壁骨折4例,横行骨折2例,横行伴后壁骨折1例。术前行关节穿刺及术中取关节周围组织送细菌培养和药敏试验。手术取出内固定物,彻底清创,1例行一期THA手术,7例采取一期植入抗生素骨水泥间隔体,术后静脉滴注及口服抗生素,定期复查红细胞沉降率(ESR)、C反应蛋白(CRP)连续两次正常后,行二期THA手术。术后定期随访,常规复查ESR、CRP,摄髋关节正侧位X线片,采用Harris髋关节评分评估髋关节功能。结果所有患者均获得随访,随访时间14-55个月,平均29.5个月。一期与二期手术间隔时间5-15个月,平均8.5个月。Harris髋关节评分从术前平均(53.8±4.9)分,提高至末次随访时平均(92.3±5.3)分,差异有统计学意义(t=33.14,P〈0.01)。随访期间无1例发生假体周围感染、假体松动及脱位。结论对继发于髋臼骨折内固定手术的髋部感染,彻底清创及应用抗生素骨水泥间隔体可有效控制感染,骨小梁金属钽杯可提供有效的骨长入。 相似文献
