Musculoskeletal injuries following seizures have a high morbidity and mortality. These injuries are often missed and the diagnosis is delayed due to a lack of clinical suspicion and appropriate investigations.We report a case of 72 years old male with simultaneous bilateral central acetabular fracture dislocation and bilateral posterior shoulder fracture dislocation secondary to an epileptic seizure. Present study high- lights the significance of clinical suspicion and clinico-radiological evaluation for diagnosis of a rare injury following episode of seizures. Simultaneous fracture dislocation of all four limbs treated with a holistic approach can lead to a good functional recovery. Surgical management with open reduction and internal fixation is preferred and replacement arthroplasty should be reserved for cases with implant failure and elderly patients.

BACKGROUNDPorous-coated cups have been widely used in acetabular reconstruction after failed treatment of acetabular fractures, and good results have been reported with the use of these cups; however, the durability and functionality of modular trabecular metal (TM) acetabular components in acetabular reconstruction after failed treatment of acetabular fractures remain unclear. This study aimed to examine the radiographic and clinical outcomes associated with the use of modular TM acetabular components for failed treatment of acetabular fractures to assess the durability and functionality of these components in acetabular reconstruction after failed treatment of acetabular fractures.

METHODSA total of 41 patients (41 hips) underwent total hip arthroplasty (THA) using modular TM acetabular components for failed treatment of acetabular fractures at our hospital between January 2007 and December 2012. Among these patients, two were lost to follow-up. Therefore, 39 patients (39 hips) were finally included in this study. The Harris hip score before and after the surgery, satisfaction level of the patients, and radiographic results were assessed.

RESULTSThe mean Harris hip score increased from 34 (range, 8-52) before surgery to 91 (range, 22-100) at the latest follow-up examination (P < 0.001). The results were excellent for 28 hips, good for six, fair for three, and poor for two. Among the 39 patients, 25 (64%) and 10 (26%) were very satisfied and somewhat satisfied, respectively. All cups were found to be fully incorporated, and no evidence of cup migration or periacetabular osteolysis was noted.

CONCLUSIONSDespite the technically demanding nature of the procedure, THA using modular TM acetabular components showed good durability and functionality and may be an effective reconstruction option for failed treatment of acetabular fractures.

Rotational acetabular osteotomy (RAO) is a well-established surgical procedure for patients with acetabular dysplasia, and excellent long-term results have been reported. However, RAO is technically demanding and precise execution of this procedure requires experience with this surgery. The usefulness of computer navigation in RAO includes its ability to perform three-dimensional (3D) preoperative planning, enable safe osteotomy even with a poor visual field, reduce exposure to radiation from intraoperative fluoroscopy, and display the tip position of the chisel in real time, which is educationally useful as it allows staff other than the operator to follow the progress of the surgery. In our results comparing 23 hips that underwent RAO with navigation and 23 hips operated on without navigation, no significant difference in radiological assessment was observed. However, no perioperative complications were observed in the navigation group whereas one case of transient femoral nerve palsy was observed in non-navigation group. A more accurate and safer RAO can be performed using 3D preoperative planning and intraoperative assistance with a computed tomography-based navigation system.

OBJECTIVETo investigate the operative reduction techniques and clinical results of surgical treatment of type C1 (AO/ASIF) acetabular fracture by posteroproximal-posteroanterior sequential reduction and internal fixation.

METHODSFrom August 2004 to January 2012, 13 patients with type C1 (AO/ASIF) acetabular fracture were treated by posteroproximal-posteroanterior sequential reduction and internal fixation. Of them, 8 cases were male and 5 cases were female with an average age of 42 years years old (ranged, 18 to 64). Pelvis 3-dimentional CT reconstruction were used to confirmed the classification of fracture, and the operation were performed during from 5 to 20 days with an average of 9.5 days. Operation time, blood loss, complications and reduction were recorded and evaluated. The function of hip joint were accessed at the final follow-up.

RESULTSThe operation time ranged from 190 to 290 min with an average of 240 min. The mean blood loss was 1 800 ml (ranged, 1 300 to 3 000 ml). One case had superficial infection and healed after 3 weeks. According to Matta reduction criteria, 8 cases obtained anatomical reduction, 4 cases got satisfied results and 1 cases got unsatisfied results. Eleven cases were followed up with an average of (24.0 +/- 8.0) months, and 2 cases were lost to follow-up. According to revised Mede d'Aubingne and Postel evaluation system, 7 cases got excellent results, 2 good, 1 moderate and 1 poor.

CONCLUSIONPosteroproximal-posteroanterior sequential reduction and internal fixation for the treatment of type C1 (AO/ASIF) acetabular fracture can achieve satisfied surgical proces and operation quality.

OBJECTIVETo discuss clinical effects of complex acetabular fracture.

METHODSFrom January 2005 to December 2010, totally 31 patients with complex acetabular fracture received surgery. There were 21 males and 10 females with an average age of 38.6 years old (ranged, 31 to 57). X-ray, CT, operation scheme and clinical efficiacy were retrospectively analyzed. American Academy of Orthopaedic Surgery standard was used to evaluate hip joint function.

RESULTSAll patients were followed up from 12 to 36 months with an average of 17.6 months. No complications and neurovascular injury occurred. One case received total hip replacement arthroplasty. There were 17 cases obtained anatomical reduction, 12 cases got satisfied reduction and 2 cases not satisfied. According to American Academy of Orthopaedic Surgery standard, 18 cases got excellent result, good in 9 cases, fair in 3 cases and poor in 1 case.

CONCLUSIONComplex acetabular fracture combine with lots of complications and easily had occurre postoperative complications. It can improve curative effect by accurate reduction and reliable fixation and maximize restoring function of hip joint.

OBJECTIVETo discuss the operative effects and evaluate how the waiting time before surgery influence the outcome of complex acetabular fractures.

METHODSFrom January 2006 to December 2008, 33 patients, 28 males and 5 females, with complex acetabular fractures were operated in our hospital. All of them were followed up for an average 24 months (ranged, 14 to 47 months). The average age was 42 years (ranged,27 to 57 years). According to the waiting time before surgery, all patients were divided into two groups, namely preoperative waiting time of more than 14 days group and preoperative waiting time of less than 14 days group. Postoperative reduction quality and long-term radiographic results were evaluated according to the Matta radiological systems. The modified Merle d' Aubigne-postel hip scoring system was used for evaluating the functional outcomes. The Mos SF-36 was used to evaluate the quality of life.

RESULTSAnatomical reduction in 28 cases, good in 4 cases, and poor in 1 case. According to the mean Merle d'Aubigne and Postel Score, 22 patients got excellent result, 4 good, 4 fair and 3 bad. Average score of the Mos SF-36 was (70.63 +/- 17.03). When time was measured as a categorical variable, an anatomical reduction and an excellent or good functional outcome were more likely if surgery was performed within 14 days. Postoperative complications: iatrogenic injuries of sciatic nerve in 2 cases, heterotopic ossification in 6 cases,traumatic osteoarthritis in 3 cases, and femoral head necrosis in 1 case.

CONCLUSIONGood image evaluation,correct approaches, appropriate time before surgery and approach, early functional rehabilitation are essential for better outcomes in the treatment of complex acetabular fractures, of which, time to surgery is a crucial and controllable prognostic factor.

OBJECTIVETo explore the best opportunity of structure reconstruction for complex acetabular fracture in order to provide the accurate time for clinical operative treatment.

METHODSComplex acetabular fracture patients were divided into experimental group (93 cases, 96 hips) and control group (98 cases, 101 hips) randomly according to the operative time. The operation of patients were done respectively at the 7th, 10th day after injury in experimental group and control group. The operative time, the excellent and good rate of reduction,the postoperative complications,the joint function (ache to walk,joint activity),the SF-36 were evaluated.

RESULTS(1) The operative time of experimental group was obviously shorter than control group according to different fracture classification. (2) According to the standard of Matta' joint function and X-ray, the experimental group was better than control group. (3) The excellent and good rate of reduction in experimental group was obviously higher than control group, according to CT scan before operation and after operation.

CONCLUSIONThe early structure reconstruction of complex acetabular fracture can obviously decrease operative time and complications, increase the rate of operative reduction.
