Doctor, When Should I Start Walking? Revisiting Postoperative Rehabilitation and Weight-Bearing Protocols in Operatively Treated Acetabular Fractures: A Systematic Review and Meta-Analysis.

Background and Objectives: Management of acetabular fractures is aimed at anatomically reducing and fixing all displaced or unstable fractures, as the accuracy of fracture reduction has been demonstrated to strongly correlate with clinical outcomes. However, there is a noticeable gap in the literature concerning the perioperative and postoperative care of patients with acetabular fractures, which ultimately can be potential risk factors for adverse outcomes and permanent disabilities. This study aimed to systematically review the available literature regarding rehabilitation practices, including weight-bearing protocols, across time points in surgically treated acetabular fracture patients and correlate these practices with functional outcomes. Methods: We systematically reviewed the Medline and PubMed databases and the Cochrane Central Register of Controlled Trials in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria were studies with adult patients (19+ years), publications from the last 10 years, articles focusing on rehabilitation or mentioning any aspect related to rehabilitation (such as weight-bearing or muscle training), and describing the surgical management of acute, isolated acetabulum fractures. Specific information was collected, including the fracture classification, time to surgery, surgical approach, surgical time, blood loss, fixation strategy, quality of reduction, postoperative rehabilitation protocol, complication rate, type(s) of complication, and outcome measurement(s). The choice(s) of surgical approach, surgical time, blood loss, and fixation strategy were stratified based on the fracture classification. The complication rate and type(s) of complication were calculated for all studies. Fractures were classified based on the Letournel classification. Results: A total of 494 articles were identified from the initial search, of which 22 (1025 patients) were included in the final review. The most common rehabilitation protocol favored isometric quadriceps and abductor strengthening exercises starting on the first postoperative day, with passive hip movement at 1-3 days postoperatively and active hip movement ranging from the first postoperative day to 4 weeks postoperatively. Partial weight-bearing with a walker or a pair of crutches was permitted from 1 to 12 weeks after surgery, and full weight-bearing was allowed depending on the patient's general condition and fracture healing state (generally at the end of 3 months). In only three studies did the patients start bearing weight in the early postoperative period (≤1 week). Meta-regression analysis was not performed due to the discrepancy between studies that reported a weight-bearing protocol ≤1 week and >1 week postoperatively. Conclusions: Our study suggests that an accelerated postoperative rehabilitation protocol, including early permissive weight-bearing, does not appear to increase the risk of loss of reduction or the rate of complications after surgical treatment of acetabular fractures. However, a proper meta-analysis was not possible, and the heterogeneity of the included studies did not allow us to conclude anything about the potential biomechanical and clinical benefits nor the negative effects related to this rehabilitation regimen in terms of functional results. There is an inconsistent use of PROMs for objectively calculating the effect size of the accelerated protocol compared with restricted weight-bearing regimes. We pose the need for higher-level evidence to proof our hypothesis.

A standard canulated screw may not fit up to 1/3 of the patients treated percutaneously for anterior column acetabular fractures-A pilot study.

A proper evaluation of the narrowings and length of the anterior acetabular column would offer better predictability and precision for implant insertion in the case of an acetabular fracture. OBJECTIVE: To determine the diameter and length of the safety corridor of the anterior column of the acetabulum in patients with available pelvic computed tomography (CT), analyze the obtained measurements against those of a standard 6.5-mm implant, and verify possible sex differences regarding these measurements. A secondary aim was to develop a method for measurement of the anterior column of the acetabulum based on CT images. MATERIALS AND METHODS: In 200 CT scans of hemipelvises we measured the diameter of two areas of narrowing and the length of the safety corridor of the anterior column. The images were submitted to multiplanar reformatting adjusted to a plane orthogonal to the bone corridor, drawn at the level of the superior pubic ramus. RESULTS: Measurement #1 had a mean value of 8.12 (2.27) mm in the overall sample and median values of 9.03 (7.76-10.48) mm in men and 6.77 (5.44-7.19) mm in women. Measurement #2 had a mean value of 7.29 (2.19) mm and median values of 8.23 (7.18-9.82) mm in men and 5.9 (4.65-7.19) mm in women. Measurement #3 had a mean value of 109.53 (13.66) mm in the overall sample and median values of 117.17 (112.9-122.9) mm in men and 100.91 (90.95-111.17) mm in women (p<0.001 all three measurements). Measurement #1 was smaller than 6.5 mm in 22.5% of the patients (of whom 90% were women). Measurement #2 was smaller than 6.5 mm in 35% of the patients (of whom 80% were women). CONCLUSIONS: This study proposed an anatomic evaluation of the anterior column of the acetabulum using conventional CT images The areas of narrowing in the anterior column had an average of 8.12 mm at the level of the pubic tubercle and 7.29 mm at the level of the acetabular fossa. The mean length of the safety corridor was 109.53 mm. In 35% of the cases, a 6.5 mm percutaneous screw would have violated the cortical bone of the safety corridor.

Reporte de caso de una niña de 9 años de edad con una fractura acetabular fisaria desplazada tratada quirúrgicamente: 5 años de seguimiento / Case report of an acetabular displaced physeal fracture in a 9-year-old girl treated surgically: follow-up of 5 years / Relato de caso de uma menina de 9 anos com fractura de acetábulo desviada tratada cirurgicamente: seguimento de 5 anos

Las fracturas acetabulares con compromiso del cartílago trirradiado (CTR) en pacientes pediátricos son muy poco frecuentes, difíciles de diagnosticar y complejas de tratar; pudiendo dejar graves secuelas. Generalmente son producto de accidentes de tránsito de alta energía cinética. Debido a su baja prevalencia no hay grandes series en la bibliografía y por ende tampoco existe un consenso terapéutico. Realizamos una puesta a punto del tema a propósito de un atípico caso de una niña de 9 años con una fractura del acetábulo con compromiso del CTR, producido por un traumatismo de baja energía cinética. Registramos su diagnóstico y tratamiento quirúrgico, evaluamos su resultado clínico - radiológico y funcional mediante el Hip Harris Score (HHS) al final de su seguimiento de 5 años.

Acetabular fractures with compromise of the triradiate cartilage (TRC) in pediatric patients are very rare, difficult to diagnose and complex to treat, also can leave serious consequences. They are generally product of high energy kinematics. Due to its low prevalence, there are no large series in the literature and therefore there is no therapeutic consensus. We carried out a recapitulation of the subject regarding an atypical case of a 9-year-old girl with an acetabulum fracture with compromise of the TRC, produced by a low kinetic energy trauma. We recorded the diagnosis and surgical treatment, and also, we evaluated the clinical-radiological and functional results through the Hip Harris Score (HHS) at the end of their 5-year follow-up.

Associated both-column acetabular fracture: An overview of operative steps and surgical technique.

The management of both-column fractures of the acetabulum is challenging for the orthopaedic surgeon. Operative treatment is usually recommended in this particular fracture pattern, as residual joint surface displacement has been shown to increase local contact stress, drastically leading to rapid cartilage destruction. In this review, we present an overview of operative steps and surgical technique for both-column acetabular fracture reconstruction. Therefore, we demonstrate how correct understanding of fracture morphology and displacement, preoperative preparation, including choice of approach and patient positioning, reduction strategies, and programmed sequential fixation, starting from superior fracture lines on the anterior acetabular column and ending on the posterior components of this fracture type, may provide satisfactory outcomes in this difficult acetabular fracture pattern.

Tratamiento quirúrgico de las fractura de pared posterior de acetábulo: resultados a corto y mediano plazo / Surgical treatment in acetabular posterior wall fractures: short and medium-term results

OBJETIVO: Evaluar los resultados radiológicos a corto y mediano plazo de pacientes operados de fractura de pared posterior de acetábulo, describir la morfología de la fractura, presencia de lesiones asociadas y la necesidad de artroplastia total de cadera (ATC) durante la evolución. MATERIAL Y MÉTODOS: Estudio retrospectivo-descriptivo de una serie consecutiva de 40 pacientes operados entre julio de 2012 y julio de 2017 por fractura de pared posterior de acetábulo. Treinta y siete hombres y tres mujeres con una edad promedio de 41 años fueron operados (mediana de seguimiento 17,7 meses). Se registró el mecanismo del accidente y presencia de lesiones asociadas. Se registraron el número de fragmentos que presentaba la fractura, presencia de impactación marginal, compromiso de la cabeza femoral, presencia de fragmentos intra-articulares y complicaciones postoperatorias. Para el análisis estadístico se utilizó el test de Wilcoxon. RESULTADOS: Todos los casos fueron secundarios a un accidente de alta energía. Un 70% de los pacientes presentó luxación posterior. La mayoría de los pacientes presentó una fractura entre 2 y 5 fragmentos (70%), 47,5% de los pacientes presentó impactación marginal, 37,5% compromiso de la cabeza femoral en zona de carga, 30% fragmentos intra-articulares. La complicación que más frecuente se observó fue la artrosis post-traumática la cual se presentó en un 22,5%. Cinco pacientes (12,5%) requirieron ATC. CONCLUSIÓN: Aunque se categorizan dentro de los patrones simples, las fracturas de pared posterior son lesiones complejas. La tomografía axial computada preoperatoria es esencial para determinar lesiones intra-articulares dada su alta frecuencia y también permite realizar un buen plan preoperatorio.

OBJECTIVE: Evaluate radiologic results in short and medium-term in surgically treated patients with acetabular posterior wall fracture. Describe fracture morphology, the presence of associated lesions and the necessity of total hip arthroplasty (THA) during the evolution. MATERIALS AND METHODS: A retrospective-descriptive study design of 40 patients treated during July 2012 and July 2017 for acetabular posterior wall fracture. 37 men and 3 women, 41 years old mean age. The mean follow-up was 17.7 months. Accident mechanism and presence of associated lesions were registered, as well as the number of fragments of the fracture, the presence of marginal impaction, femoral head compromise, intra-articular fragments and postoperatory complications. Wilcoxon test was used for the statistical analysis. RESULTS: Every case resulted due to a high energy accident. 70% of patients had posterior luxation of the hip. 70% of patients presented 2 to 5 fragments. 47.5% of patients presented marginal impaction, 37.5% compromised femoral head and 30% intra-articular fragments. The most frequent complication was post-traumatic arthrosis, which appeared in 22.5% of patients. Five patients required THA. CONCLUSION: Though it is categorized as simple fracture pattern, posterior wall fractures are complex. Preoperatory CT scan is essential to determine intra-articular lesions due to its high frequency and permits to plan an adequate intervention.

Total Hip Arthroplasty After Prior Acetabular Fracture: Infection Is a Real Concern.

BACKGROUND: Acetabular 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). METHODS: About 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. RESULTS: Patients 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. CONCLUSION: The 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.

Morphological abnormalities of the hip in acetabular fractures.

Poor prognosis factors in surgical treatment of acetabular fracture-dislocations have been well established but there is little information about how morphological abnormalities of the hip may affect the surgical outcome. Hip anatomy has a wide range of variations. Morphological abnormalities of the hip can also be observed in patients with acetabular fractures. We present a case of a complication in a patient with a complex acetabular fracture, acetabular retroversion and femoroacetabular impingement. A 31-year old male patient was transferred to our trauma center following a high speed road traffic accident. Trauma series CT revealed cerebral contusion, subdural hematoma, aortic dissection and a left transverse plus posterior wall acetabular fracture. The left hip was reduced and the acetabular fracture was treated with a Kocher Langenbeck approach in prone position. The pelvic X- ray evidenced an anatomic reduction and signs of acetabular retroversion with positive posterior wall sign and crossover sign. CT scan evidenced increased alpha angle in the femoral head neck junction. During the follow up, 2 months after the acetabular fixation, patient suffered a posterior left hip dislocation and a total cementless hip arthroplasty was performed. Patients with acetabular retroversion and femoroacetabular impingement (CAM lesion) may be at risk of posterior dislocation. The influence of acetabular version and impingement may be also closely involved in how challenging the determination of hip stability can be in patients with posterior wall acetabular fractures. Acetabular retroversion and FAI may be related to the dislocation of unstable patterns with small fragments (wall sizes less than 20%). In this case postoperative precautions were not enough. We believe capsular reattachment with anchors and bracing may be useful in these selected cases. As these patients are not candidates for retroPAO (the recommended treatment for acetabular retroversion) maybe arthroscopic anterior wall riming and CAM resection should be performed at an early stage to decrease or avoid fulcrum.

Complicación de una fractura bilateral acetabular después de múltiples cirugías y 30 años de evolución. Presentación de un caso / Complication of a bilateral acetabular fracture after multiple surgeries and 30 years of evolution. Presentation of a case

Resumen Fractura acetabular bilateral, reducción abierta y fijación interna, sin lograrse reducción anatómica; requirió colocación de prótesis totales a corto plazo, ambas cementadas. Se llevó a cabo una revisión de ambos componentes de cadera izquierda a los ocho años por aflojamiento de la copa y del vástago, con componentes no cementados. El fémur evolucionó de manera satisfactoria, no así el acetábulo, que requirió seis revisiones subsecuentes, con injertos óseos y colocación de refuerzos metálicos, inicialmente muy estables, pero con ruptura de tornillos y falta de osteointegración tanto de los implantes como de los injertos a los 12 y 18 meses en los diferentes eventos quirúrgicos. Desarrolló pseudoaneurisma de la arteria iliaca externa izquierda, tratado por un cirujano vascular; se complicó con infección local primero e infección profunda de cadera izquierda por Staphylococcus aureus después. Se trató con retiro de los implantes en iliaco y utilizando polimetilmetacrilato con antibiótico como relleno del gran defecto óseo mientras se controló la infección, terminando con una prótesis de rescate en silla de montar (Link, Hamburgo). En la actualidad, tiene buena función, sin dolor, pero con movilidad limitada, sobre todo la flexión. La cadera derecha se ha revisado una sola vez; la copa acetabular empezó a migrar cefálica y vertical, pero sin perder estabilidad, al poco tiempo del aflojamiento de la izquierda; nunca desarrolló compromiso del vástago femoral, permitiéndole una función aceptable y siendo «su pierna buena¼ durante el tiempo de disfunción de la cadera izquierda. Se revisó colocando injerto óseo estructural con dos cabezas femorales de cadáver y cementando una nueva copa. La recuperación de la paciente ha sido muy buena; se ha reintegrado a la vida activa, en la que se vale por sí misma para todas sus actividades cotidianas; utiliza una muleta con la mano derecha, maneja una camioneta, no tiene dolor.

Abstract Bilateral acetabular fracture, open reduction and internal fixation, without achieving anatomical reduction; it required placement of short-term total prostheses, both cemented. We made a revision of both left hip components in the eighth year because of loosening of the cup and stem, with uncemented components. The femur evolved satisfactorily, but the acetabulum required six subsequent revisions, with bone grafts and placement of metal reinforcements, initially very stable, but with screw rupture and lack of osseointegration of both implants and grafts at 12 and 18 months in the different surgical events. She developed pseudoaneurysm of the left external iliac artery, treated by a vascular surgeon; it got complicated with local infection first and later, deep infection of the left hip by Staphylococcus aureus. The implants were removed from the iliac and polymethylmethacrylate with antibiotics was used to fill the large bone defect while the infection was being controlled, ending with a saddle rescue prosthesis (Link, Hamburg). It currently has a good function, without pain, but with limited mobility, especially flexion. The right hip has only been checked once; the acetabular cup began to migrate cephalically and vertically, but without losing stability, shortly after the loosening of the left one; it never developed femoral stem involvement, allowing acceptable function and being «her good leg¼ during the time of the left hip dysfunction. It was reviewed by placing a structural bone graft with two femoral heads from a corpse and cementing a new cup. The patient's recovery has been very good, returning to an active life in which she is self-sufficient in all her daily activities; uses a crutch with her right hand, drives a van, is pain-free.

[Kocher-Langenbeck approach in the surgical management of posterior wall fractures of the acetabulum]. / Abordaje de Kocher-Langenbeck en el manejo quirúrgico de las fracturas posteriores del acetábulo.

Surgical treatment of acetabular fractures is indicated in displaced cases in order to restore and stabilize the hip joint and the pelvic ring integrity. Posterior structure fractures must be treated through posterior pelvic surgical approaches. The Kocher-Langenbeck is the most recommended approach for the majority of posterior acetabular fractures.

Las fracturas de acetábulo son lesiones articulares que en la mayoría de los casos requieren manejo quirúrgico para restablecer la integridad de la articulación de la cadera y el anillo pélvico. Las fracturas de elementos posteriores del acetábulo deben ser tratadas por abordajes posteriores. El de Kocher-Langenbeck es el más recomendado en la mayoría de los casos.

Resumen: Antecedentes: Las lesiones pélvicas severas por alta energía en pacientes pediátricos son raras, y más, asociadas con fracturas acetabulares, siendo lesiones que ponen en riesgo la vida del niño. Método: Se presenta el caso de un individuo pediátrico con diagnóstico de fractura de pelvis Torode y Zieg tipo IVd con datos clínicos y radiográficos revisados retrospectivamente. Caso clínico: Niño de 12 años de edad politraumatizado, con fractura de pelvis inestable, tratado de manera multidisciplinaria. Se realizó estabilización en la unidad de terapia intensiva, laparotomía por el Servicio de Cirugía General, manejo ortopédico con reducción cerrada, fijación interna de la fractura-luxación sacroilíaca, con posterior reducción abierta y fijación interna de la fractura acetabular derecha; presentó adecuada evolución clínica. Conclusiones: El diagnóstico de una fractura de acetábulo Torode y Zieg IVd es una indicación absoluta de manejo quirúrgico. La atención multidisciplinaria es esencial para preservar la vida de los sujetos con lesiones de pelvis inestable.

Abstract: Background: High-energy severe pelvic injuries in pediatric patients are rare, particularly those associated with acetabular fractures. They are life threatening injuries. Method: We report the case of a pediatric patient with a diagnosis of a Torode/Zieg IVd pelvic fracture. The clinical and radiographic data was reviewed retrospectively. Clinical case: Male, 12 year-old polytraumatized patient with an unstable pelvic fracture who underwent multidisciplinary treatment. He was stabilized in the intensive care unit; the general surgery service performed laparotomy; orthopedic management consisted of closed reduction and internal fixation of the sacroiliac fracture-dislocation and later of open reduction and internal fixation of the right acetabular fracture. The patient´s clinical course was appropriate. Conclusions: A diagnosis of a type IVd Torode/Zieg fracture is an absolute indication for surgical management. A multidisciplinary approach is essential to save the life of patients with unstable pelvic lesions. This case shows the complexity of an unstable pelvic fracture associated with multiple injuries, due to a rather infrequent mechanism of injury (being crushed by a tree) in a patient with an immature skeletal system.

Marginal impaction in posterior wall fractures of the acetabulum.

OBJECTIVE: The purposes of this study were to describe the CT features of isolated posterior acetabular wall fractures with associated marginal impaction and to discuss the potential therapeutic implications of recognizing this type of fracture. CONCLUSION: Marginal impaction is an important cause of articular incongruity that adversely affects prognosis. Radiologists should be capable of identifying posterior acetabular wall fracture patterns because they may be the first to suggest diagnoses.

Reducción cerrada y fijación percutánea retrograda de una fractura transversa del acetábulo: reporte de un caso / Closed reduction and retrograd percutaneous fixation of transverse acetabular fracture: a case report

El tratamiento quirúrgico de la fracturas del acetábulo es uno de los retos más demandantes para el cirujano ortopedista y traumatólogo. La reducción abierta y fijación interna ha sido el método estándar para el manejo de estas fracturas. Sin embargo, se ha relacionado con muchas complicaciones. Para disminuir estos riesgos, se han desarrollado procedimientos percutáneos mínimamente invasivos. Las técnicas percutáneas son atractivas porque ofrecen estabilidad conservando el hematoma de la fractura y sin disrupción del periostio como ocurre en la técnica abierta. Se presenta el caso de un paciente masculino de 19 años quien presentó una fractura transversa de acetábulo izquierdo con fractura diafisiaria del fémur ipsilateral posterior a un accidente automovilístico. El acetábulo se resolvió mediante reducción cerrada y fijación interna con 2 tornillos retrógrados percutáneos. En vista de la reducción anatómica y la estabilidad conseguida, se indico la carga inmediata completa de la extremidad. Se presenta su resolución y evolución

The surgical treatment of acetabular fractures is one of the most demanding challenges for the orthopedic surgeon and orthopedist. Open Reduction and Internal Fixation has been the gold standard for the management of these fractures. However, it has been associated with many complications. To reduce these risks, minimally invasive percutaneous procedures have been developed. Percutaneous techniques are attractive because they offer stability and preserve the fracture hematoma without disruption of the periosteum through a formal open technique. We present a case of a 19 year old male patient who presented a left acetabular transverse fracture with ipsilateral femur shaft fractures after a car accident. It was resolved by closed reduction and internal fixation with 2 retrograde percutaneous screws. As an anatomic reduction and stability has achieved, immediate full weightbearing was indicated. Resolution and evolution is presented

Tratamiento quirúrgico de fracturas transversas más pared posterior de acetábulo / Surgical treatment of transverse and posterior acetabular wall fractures

Objective: Describe our experience in the surgical treatment of transverse with posterior wall fractures of the acetabulum, the elements that help in the choice of the approach and functional and radiological results of this type of injury. Methods: We retrospectively evaluated 9 patients (9 fractures) with transverse and posterior wall fractures operated between August 2008 and September 2010. Six patients were men and 3 women with an average age of 40.4 years. We reviewed the surgical protocols, the perioperative data and the pre and post operative radiological images. We registered the complications and the functional results with the Merle D’Aubigne and Postel score. Results: All cases were considered secondary to high energy mechanisms. Five patients had posterior dislocation of the hip and 4 had central dislocation. Eight patients had associated injuries. In the early postoperative period there were no complications. One patient had posttraumatic osteoarthritis and required total hip arthroplasty. The average of Merle d’Aubigne score was 16.1 points. Conclusion: Surgical treatment for this type of injury had good results in this group of patients.

Functional Outcome after Operative Treatment of Displaced Fractures of the Acetabulum: A 12-month to 5-year Follow-up Investigation.

PURPOSE: To review our experience with 82 surgically treated displaced acetabular fractures over a 4-year period. PATIENTS AND METHODS: Ninety-three consecutive displaced acetabular fractures were consecutively operated on at Level I Trauma Center from January 1, 2000 through December 31, 2003, and 82 were available for review with a minimum of 12-month follow-up. Clinical (Merle D'Aubigné modified by Matta et al.) and radiographic (Matta) outcomes were evaluated. Complications and secondary operative procedures were documented. RESULTS: Anatomical reduction was achieved in 89% of the patients. At follow-up examination 12-60 months postoperatively (mean 32 months), clinical results were satisfactory in 65 patients (79.2% of the cases), with 14 excellent and 51 good results, and roentgenographic results were satisfactory in 70 patients (85.4% of the cases). Complications included a 12.2% incidence of sciatic nerve palsy (10 patients, two postoperative and eight posttraumatic), a 2.4% incidence of intraoperative vascular lesion (one external iliac artery and one external iliac vein), a 1.2% incidence of postoperative loss of reduction, a 1.2% incidence of infection, a 1.2% incidence of Brooker et al. class IV heterotopic ossification, a 2.4% incidence of posttraumatic osteoarthritis, and a 2.4% incidence of osteonecrosis of the femoral head. CONCLUSIONS: Operative treatment is an effective method for the management of displaced acetabular fractures. Clinical and roentgenographic results correlate closely with an anatomic reduction. Low complication rate can be expected if adequate preoperative assessment and planning is performed. Strategies to minimize the risk of thromboembolism and heterotopic ossification on the basis of mechanical pneumatic compression and antiinflammatory nonsteroidal drugs, respectively, are reliable techniques for these injuries.
