Application of self-made spring plate for treatment of acetabular posterior wall fractures / 中国修复重建外科杂志

Objective: To investigate the application and effectiveness of self-made spring plate in surgical treatment of acetabular posterior wall fracturejavascript:void(0)s. Methods: Between June 2013 and June 2017, 38 patients with acetabular posterior wall fractures were treated. There were 27 males and 11 females with an average age of 53 years (range, 28-68 years). The injury caused by traffic accident in 18 cases, falling from height in 15 cases, and tumble in 5 cases. There were 4 cases of simple posterior wall fracture, 18 cases of posterior wall fracture with posterior dislocation of hip joint, 10 cases of posterior wall fracture with posterior column fracture, and 6 cases of posterior wall fracture with transverse fracture. The time from injury to admission was 1-4 days (mean, 2.5 days). The time from injury to operation was 4-8 days (mean, 5 days). After fracture reduction via the Kocher-Langenbeck approach (35 cases) or the combined ilioinguinal approach (3 cases), the spring plate was used to press the posterior wall fracture, and then the reconstruction plate was pressed against the spring plate and fixed to the posterior column. Results: All the incisions healed by first intention. All patients were followed up 12-36 months (mean, 28 months). Five cases of post-traumatic sciatic nerve injury and 2 cases of sciatic nerve injury caused by traction during operation were fully recovered at 3 months after operation. The imaging examination showed that all the fractures healed. The fracture healing time was 10-16 weeks (mean, 12 weeks). There was no ruptures or failures of internal fixation during the follow-up period. There were 2 cases of femoral head necrosis, 1 case of traumatic arthritis, and 1 case of osteomyositis at last follow-up. The hip joint function was rated as excellent in 27 cases, good in 5 cases, fair in 2 cases, and poor in 4 cases according to the Harris scores at 12 months after operation. Conclusion: For the acetabular posterior wall fracture, it has the advantages of easy to use and reliable fixation that the posterior wall fracture is fixed with spring plate firstly, and the spring plate is pressed to fix the posterior column with the reconstruction plate finally.

Progress in treatment and research of acetabular posterior wall fracture / 中华创伤骨科杂志

Fracture of the posterior wall is the most common type of acetabular fractures,but it is often associated with such injuries as dislocation of hip joint,femoral head fracture and lesion of sciatic nerve.Latest researches have found that treatments of fracture of the acetabular posterior wall often lead to unsatisfactory outcomes because its prognosis is influenced by a variety of factors,including its associated injuries,subtypes,and quality and timing of surgical reduction.This review summarizes extensive clinical experiences in treatment of the fracture and available literature concerning management and research of the fracture so as to provide enough information for junior surgeons to have a better understanding of the fracture and its treatment,improving the prognosis of the fracture and effectively avoiding the pitfalls in their clinical practice.

Usefulness of Spring Plate for Acetabular Posterior Wall Fracture Including Small Fragment

PURPOSE: We applied internal fixation using a spring plate against an acetabular posterior wall fracture including small fragments and then evaluated the clinical and radiological results and want to understand the usefulness of the spring plate. MATERIALS AND METHODS: Fifteen patients in whom fixation was difficult using leg screws or a metal plate because of a small bone fragment, in patients with posterior wall acetabular fractures who presented in our hospital since August of 2011 to March of 2014 were enrolled. The mean age was 42.6 years (range 24-54 years) with relatively young patients, and they were followed-up for at least one year. We analyzed the rate of reduction after surgery using the classification of Matta in radiographs, and the classification of Borrelli in 3-dimensional computed tomography (CT) and clinical results were evaluated using the clinical grading system. RESULTS: There were five cases of anatomical reduction, 9 cases of imperfect reduction, and 1 case of unsatisfactory reduction according to the classification of Matta. Except for one case during the follow-up period, the union of bone was successful without failure of fixation and the clinical results were 6 cases of excellence, 8 cases of good, and 1 case of failure. Articular displacement was also evaluated in postoperative CT scan according to Borrelli's criteria. The mean of gap and step off was 2.04 mm, 1.3 mm. CONCLUSION: Use of leg screw fixation and so on in posterior wall fractures including a small fragment of the acetabular rim is not easy. However the method using spring plate fixation enables relatively accurate reduction and fixation for a small fragment and the clinical outcome showed satisfactory results.

Arthroscopic Reduction and Transportal Screw Fixation of Acetabular Posterior Wall Fracture: Technical Note / 대한고관절학회지

Acetabular fractures can be treated with variable method. In this study, acetabular posterior wall fracture was treated with arthroscopic reduction and fixation using cannulated screw. The patient recovered immediately and had a satisfactory outcome. In some case of acetabular fracture could be good indication with additional advantages of joint debridement and loose body removal. So, we report our case with technical note.

Reconstruction of Acetabular Posterior Wall Fractures

BACKGROUND: The results after acetabular fracture are primarily related to the quality of the articular reduction. We evaluated the results of internal fixation of posterior wall fractures with using three-step reconstruction. METHODS: Thirty-three patients (mean age at the time of injury, 47.9 years; 28 males and 5 females) were followed for a minimum of 2 years after surgery. The three-step reconstruction included 1) preservation of soft tissues and reduction of the marginally impacted osteochondral (articular) fragments using screws, 2) filling the impacted cancellous void with a bone graft, and 3) reinforcement with buttress-plating. Clinical evaluation was done according to the criteria of D'aubigne and Postel, while the radiological criteria were those of Matta. The associated injuries and complications were evaluated. RESULTS: The clinical results were excellent in 15 (45.5%) patients and they were good in 5 (15.2%), (i.e., satisfactory in 60.7%), while the radiologic results were excellent in 10 (30.3%) and good in 14 (42.4%) (satisfactory in 72.7%). Heterotopic ossification was common, but this did not require excision, even without prophylactic treatment with indomethacin. Deep infection was the worst complication and this was accompanied by a poor outcome. CONCLUSIONS: This study confirms that three-step reconstruction facilitates accurate and firm reduction of displaced posterior wall fractures of the acetabulum. Therefore, we anticipate less long-term arthrosis in the patients treated this way.

Surgical Treatment of Posterior Wall Fractures of the Acetabulum

PURPOSE: To evaluate the results of surgical treatment of posterior wall fractures of the acetabulum and to determine the factors affecting the results. MATERIALS AND METHODS: Thirty-one posterior wall fractures were reviewed; 7 type A1-1, 19 type A1-2 and 5 type A1-3 by AO classification. Postoperatively, the accuracy of the reduction was evaluated. At the final follow-up, clinical and radiographic results were evaluated with medical records and radiographs. The factors affecting the results were determined. RESULTS: The reduction was graded as anatomical in 22 patients, imperfect in seven and poor in two. The clinical result was excellent in 21 hips, good in six, fair in three and poor in one. The quality of the reduction was strongly associated with the clinical result. The radiographic result was excellent in 22 hips, good in five, fair in two and poor in two. The clinical result was related closely to the radiographic result. Complications were osteoarthritis in three patients, osteonecrosis of the femoral head in one, heterotopic ossification in one, penetration of a screw into the joint in one and iatrogenic sciatic nerve injury in one. The factors affecting the clinical results were fracture patterns, the surgeon's experience, the accuracy of the reduction and late complications. CONCLUSION: In this present series of posterior wall fractures, as their prognosis depends on the severity of the injury and the accuracy of the reduction, satisfactory result can be obtained by anatomical reduction with thorough preoperative planning and the surgeon's experience.
