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.

Anatomic structure of acetabular fractures are complex and operative exposure and fixation are extremely difficult. For those obviously displaced acetabular fractures, close reduction is doomed to cause deformed healing. Open reduction with internal fixation (ORIF) not only results in anatomic reduction, but also brings complications. No matter which method will be adopted, traumatic arthritis or avascular necrosis of femoral head might occur. In order to treat acetabular fractures more effectively, orthopedic surgeons should be required to fully master the acetabular anatomy, biomechanics, classification and the necessary knowledge for complication prevention.

OBJECTIVETo explore the operative indications and operative methods of primary total hip arthroplasty for acetabular fracture and to observe the clinical curative effect.

METHODSWe retrospectively summarized and analyzed the traumatic conditions, fracture types, complications, operative time, operative techniques, and short term curative effect of 11 patients (10 males and 1 female, with a mean age of 42.4 years) with acetabular fracture who underwent primary total hip arthroplasty.

RESULTSThe patients were followed up for 6-45 months (mean=28 months). Their average Harris score of postoperative hip joint was 78.

CONCLUSIONUnder strict mastery of indications, patients with acetabular fracture may undergo primary total hip arthroplasty, but stable acetabular components should be made.

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 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 investigate the clinical usage of percutanious retrograde acetabular anterior horn screw fixation.

METHODSFrom June 2006 to November 2011,27 patients with anterior horn accetabular fractures were treated with percutaneous retrograde screw. There were 20 males and 7 females with an average age of 35 years (ranged,20 to 61). According to Tile classification,type A was in 5 cases,type B was in 18 cases and type C was in 4 cases. The intra-operative blood loss volume, fractured reduction and screw location were observed.

RESULTSPostoperative X-ray and CT scan showed good reduction. According to the standard of Matta, 10 cases got excellent results, 15 good and 2 poor. All fractures healed and no complications such as neurovascular injuries and femoral head necrosis were found.

CONCLUSIONPercutanious retrograde acetabular anterior horn screw technique have advantages of little trauma, less blood loss volume, reliable fixation, which can be effectively used in clinic.

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 explore the treatment methods and outcome of posterior wall fractures of the acetabulum.

METHODSThe data of 31 patients (25 males and 6 females, aged 19-59 years, mean: 40.5 years) with posterior wall fractures of the acetabulum hospitalized in our department from 2002 to 2006 were analyzed retrospectively in this study. The types of fractures, number of fragments, combined dislocations, and sciatic nerve function were documented before admission. All the fractures were treated with open reduction and internal fixation. Based on the fracture type and site, either screws alone or reconstructive plates were used. The patients were immobilized for an average of 12 weeks before partial weight bearing was permitted. After follow-up for 12-70 months (43.6 months on average), modified Merle d'Aubigne score was adopted to evaluate the outcomes of the operations.

RESULTSThe percentages of the excellent, good, fair and poor results were 48.4%, 41.9%, 6.5%, and 3.3%, respectively, with a good to excellent rate of 90.2%. Idiopathic sciatic nerve injury occurred in only one case.

CONCLUSIONSThe sciatic nerve should be routinely exposed and protected during the surgery. The type of fixation should be based on the fracture type and site. Prolonged immobilization may be helpful in improving the final outcomes.

OBJECTIVETo study the occurrence and radiograph features of the acetabular retroversion in hip dysplasia, and to evaluate the effects on the retroversion by the traditional maneuvers in the periacetabular osteotomy.

METHODSBernese periacetabular osteotomy was performed to 45 continuous dysplastic hips (43 patients) from December 2001 to November 2003. There were 37 female (39 hips) and 6 male (6 hips), average age was 28.9 (range, 15-45). The diagnosis of acetabular retroversion was based on the "cross-over" and "posterior wall" signs on the standard radiographs of the patients pre- or postoperatively.

RESULTSAmong total 45 hips, the "cross-over" sign was positive in 8 hips, whereas including the "posterior wall" sign positive in 5 hips. The occurrence of retroversion was 17.8%. And the cross-over points were located within the superior 1/3 of the acetabulums in all cases. After the osteotomy, all the cross-over points moved to the inferior 1/3 of the acetabulums, and the "posterior wall" sign was seen in all 8 cases.

CONCLUSIONSApproximately one sixth of the patients with acetabular dysplasia have retroversion in which the superior 1/3 of the acetabulum faces posterolaterally. The retroversion can be identified with the standard AP pelvic radiographs. With the traditional maneuvers in periacetabular osteotomy, the retroversion will be aggravated in these patients.
