Percutaneous treatment of pelvic and acetabular fractures in obese patients

A body mass index (BMI) greater than 30 is becoming increasingly common in the United States. Surgery for pelvic and acetabular fractures in this population is particularly problematic because conventional treatment often requires large surgical exposures. The surgery for both these fractures is technically difficult because of the volume of soft tissue and proneness to complications. Wound problems and infections are particularly common after open surgery in obese patients, and these increase linearly with the BMI. In this article, we present a small consecutive series over 14 months on obese patients who underwent percutaneous treatment of their pelvic or acetabular fractures.     

陈旧性髋臼骨折的治疗

目的探讨陈旧性髋臼骨折手术和影响临床结果的相关因素。方法2001年2月～2005年7月，收治陈旧性髋臼骨折37例，其中简单型骨折10例，复合型骨折27例。受伤至手术时间平均44．8d，选择Kocher—Langenbeek入路6例，髂腹沟入路1例，延长髂腹沟人路2例，前后联合入路28例。手术平均耗时226min，术中平均失血l798mL。结果全部患者平均随访18．9个月，采用Matta的复位标准以及改良的D’Aubigne和Postel临床结果评分。解剖复位31例，不满意4例，差2例；临床结果优21例，良9例，一般5例，差2例，优良率为81．1％。股骨头坏死1例，异位骨化11例，坐骨神经一过性麻痹4例。结论除单纯的后壁或／和后柱、前壁与前柱骨折选择单一的入路外，对于陈旧性髋臼骨折原则上采用前后联合入路或延长的髂腹沟人路；骨关节炎的发生与骨折的严重程度有关；股骨头坏死与术前股骨头是否向内或向后移位并无直接关系；临床结果、手术耗时和术中失血不仅与骨折程度和损伤至手术的时间有关，而且与手术医生的经验有关。     

Management of acetabular fractures in elderly patients

Management of acetabular fractures in elderly patients is challenging. The challenges arise due to associated medical comorbidities, poor bone quality and comminution. There are multiple modalities of treatment. the exact algorithms or treatment remain undefined. Treatment is still based on experience and some available evidence. The options include conservative treatment, percutaneous fixation, open reduction internal fixation and the acute fix and replace procedure. There is a well recognised risk of each treatment option. We present a narrative review of the relevant available evidence and our treatment principles based on experience from a regional tertiary pelvic-acetabular fracture service.

Total hip arthroplasty in acetabular fractures

Total Hip Arthroplasty (THA) is a well-accepted treatment for established hip arthritis following acetabular fractures. If a conservatively managed or operated case progresses to non-union/mal-union failing to restore the joint integrity, it may eventually develop secondary arthritis warranting a total hip arthroplasty. Also, in recent years, acute total hip arthroplasty is gaining importance in conditions where the fracture presents with pre-existing hip arthritis, is not amenable to salvage by open reduction and internal fixation, or, a poor prognosis is anticipated following fixation.There are several surgical challenges in performing total hip arthroplasty for acetabular fractures whether acute or delayed. As a separate entity elderly patients pose a distinct challenge due to osteoporosis and need stable fixation for early weight bearing alleviating the risk of any thromboembolic event, pulmonary complications and decubitus ulcer. The aim of surgery is to restore the columns for acetabular component implantation rather than anatomic fixation. Meticulous preoperative planning with radiographs and Computed Tomography (CT) scans, adequate exposure to delineate the fracture pattern, and, availability of an array of all instruments and possible implants as backup are the key points for success. Previous implants if any should be removed only if they are in the way of cup implantation or infected. Press fit uncemented modern porous metal acetabular component with multiple screw options is the preferred implant for majority of cases. However, complex fractures may require major reconstruction with revision THA implants especially when a pelvic discontinuity is present.

Outcome of total hip arthroplasty in patients with failed open reduction and internal fixation of acetabular fractures

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.

Acetabulum fractures in elderly patients: A review

Fractures of the acetabulum in elderly patients were often caused by low energy trauma. Fractures involving anterior column are more common and often associated with impaction and comminution. Osteoporosis further complicates the management. Percutaneous fracture fixation has low morbidity but it is a technically demanding procedure. Open reduction and fracture fixation is done with or without simultaneous total hip replacement. Delayed total hip replacement is considered in posttraumatic arthritis patients. Patients with minimal displaced fractures, associated both-column fractures with secondary congruence of joint and patients who are medically unfit for surgery can be managed non-operatively. Whatever be the method of management, these elderly patients should be mobilised as early as possible.

Higher altitude leads to increased risk of venous thromboembolism after acetabular and pelvic ring injury

IntroductionThere is a high post-operative incidence of venous thromboembolisms (VTEs), specifically deep vein thrombosis (DVT) and pulmonary embolism (PE), in pelvic ring and acetabular fractures, and identification of risk factors for VTEs is crucial to decrease this highly morbid complication. High altitudes have a known physiological effect on the body that may predispose patients to developing VTEs in the postoperative period. The purpose of this study was to investigate the relationship between pelvic ring and acetabular fractures occurring at high altitudes and the development of postoperative VTEs.MethodsIn this retrospective study, the Truven MarketScan claims database was used to identify patients who underwent surgical fixation of a pelvic ring and/or acetabular fracture from January 2009 to December 2018 using Current Procedural Terminology (CPT) codes. Patient characteristics, including medical comorbidities, were collected. The zip codes of where the surgeries took place were used to determine recovery altitude and patients were separated into either the high altitude (>4000 feet) or low altitude (<100 feet) cohorts. Chi-squared and multivariate analyses were performed to investigate the association between altitude and the development of VTE postoperatively.ResultsIn total, 68,923 patients were included for analysis. At 30-days postoperatively, a higher altitude was associated with increased odds of developing a PE (OR 1.47, p = 0.019). At 90-days postoperatively, a higher altitude was associated with increased odds of DVT (OR 1.24, p = 0.029) and PE (OR 1.63, p < 0.001).ConclusionSurgical fixation of pelvic ring and acetabular fractures performed at a higher altitude (>4,000feet) are associated with increased odds of developing a PE in the first 30 days as well as developing a DVT or PE at 90 days postoperatively. Future prospective studies are needed to further elucidate the causality of altitude on the development of postoperative VTEs.     

Survivorship of the native hip joint after percutaneous repair of acetabular fractures in the elderly

Our purpose was to examine survivorship of the native hip joint in patients ages 60 and over who underwent percutaneous reduction and fixation of acetabular fractures. A retrospective review at a University Level I Trauma Center was performed. Our institutional trauma database was reviewed. Patients aged 60 or older treated with percutaneous reduction and fixation of acetabular fractures between 1994 and 2007 were selected. 79 consecutive patients with 80 fractures were identified. Rate of conversion to total hip arthroplasty were used to construct a Kaplan–Meier curve showing survivorship of the native hip joint after treatment. 75 fractures had adequate clinical follow-up with a mean of 3.9 years (range 0.5–11.9 years). Average blood loss was 69 cc and there were no postoperative infections. 19/75 (25%) were converted to total hip arthroplasty at a mean time of 1.4 years after the index procedure. Survivorship analysis demonstrated a cumulative survival of 65% at 11.9 years of follow-up. There were no conversions to arthroplasty beyond 4.7 years postoperatively. There were no statistically significant associations between conversion to arthroplasty and age, sex, closed vs. limited open reduction, and simple vs. complex fracture pattern. Percutaneous fixation is a viable treatment option for patients age 60 or greater with acetabular fractures. Rates of conversion to total hip arthroplasty are comparable to open treatment methods and if conversion is required, soft tissues are preserved for future surgery.

The incidence and trauma mechanisms of acetabular fractures: A nationwide study in Finland between 1997 and 2014

PurposeInformation on the incidence of acetabular fractures of the pelvis is limited. Epidemiological data is often based on specific trauma registers, individual trauma centres or on trends of all pelvic fractures grouped together. The primary aim of this study was to determine the incidence and trends of hospital-treated acetabular fractures in the Finnish population from 1997 to 2014. The secondary aim was to assess the trauma mechanisms involved.MethodsThe Finnish National Hospital Discharge Register collects inpatient data from all public and private medical institutions in Finland and covers the entire Finnish population of 5.5 million. For this study, we selected all persons 18 years of age or older who were admitted to hospital for the treatment of an acetabular fracture between 1997 and 2014. The main outcome variable was the annual number of patients hospitalised with a main or secondary diagnosis of acetabular fracture of the pelvis.ResultsThe overall crude incidence of acetabular fractures increased slightly (from 6.4/100 000 persons/year to 8.1/100 000 persons/year) from 1997 to 2014 while the age-standardised incidence rate remained at a similar level (7.1/100 000/persons/year in 1997 and 7.2/100 000/persons/year in 2014). An incidence increase was observed in the elderly population, whereas the incidence of acetabular fractures in the younger population (mostly high energy traumas) remained stable. The most frequent trauma mechanism for acetabular fractures was fall on the same level (47%).ConclusionsThe incidence of acetabular fractures increased slightly in Finland between 1997 and 2014. This increase was observed especially in the elderly population and the ageing of the population largely explains the rise. The incidence of acetabular fractures in the younger population decreased. The most common trauma mechanism was falling on the same level.
