BACKGROUND: Posterior wall fractures of the acetabulum with posterior dislocation of the acetabular joint mostly require the operation of open reduction and internal fixation. Different materials can be chosen for internal fixation operation. OBJECTIVE: To explore the effect of acetabular three-dimensional memory fixation system on acetabular posterior wall fractures accompanying the acetabulum joint dislocation. METHODS: A retrospective analysis was performed on clinical data of 92 cases of acetabular posterior wall fracture and dislocation at the Heze Municipal Hospital of Shandong Province from February 2010 to February 2014. All patients received the operation of open reduction and internal fixation. They were divided into three-dimensional memory fixation group (45 cases) and reconstruction titanium plate group (47 cases) according to different fixators. All patients were followed up for 12 months after fixation. RESULTS AND CONCLUSION: The operation time and intraoperative blood loss were significantly longer or higher in the reconstruction titanium plate group than in the three-dimensional memory fixation group (P < 0.05). Harris score was significantly greater in the three-dimensional memory fixation group than in the reconstruction titanium plate group during final follow-up (P < 0.05). Thromboembolic complications or deep infection were not detected after fixation in both groups. These findings confirm that three-dimensional memory fixation system obtained good effects in the treatment of the posterior wall fractures of the acetabulum with posterior dislocation. © 2015, Journal of Clinical Rehabilitative Tissue Engineering Research.

BACKGROUND: Intertrochanteric fracture is often found in osteoporotic elderly patients, the commonly used treatment includes intramedullary and extramedullary fixations, and joint replacement. OBJECTIVE: To compare the clinical effect of proximal femoral intramedullary nail and hip arthroplasty in the treatment of intertrochanteric fracture. METHODS: 198 patients of intertrochanteric fracture recruited from Heze Municipal Hospital from August 2009 to August 2013, were divided into two groups. Each group had 99 patients, receiving proximal femoral intramedullary nail and hip arthroplasty, respectively. RESULTS AND CONCLUSION: The average operation time, intraoperative blood loss and hospital stays in the proximal femoral intramedullary nail group were significantly shorter, while the healing time of fracture was significantly longer than that in the hip arthroplasty group. At postoperative 1 year, there was no statistical difference in the Harris score, the excellent and good rate of hip function, and the overall incidence of complications between the two groups. Experimental findings indicate that, both proximal femoral intramedullary nail and hip arthroplasty are biocompatible and effective in the treatment of intertrochanteric fracture, and each technique has their advantages and disadvantages, we should choose the proper technique according to the patient’s condition. © 2015, Journal of Clinical Rehabilitative Tissue Engineering Research , All Rights Reserved.

BACKGROUND: Currently, the treatment methods of lumbar burst fractures include anterior spinal approach, posterior spinal approach, and anterior combined with posterior approach. However, it is still controversial which the best approach is for lumbar burst fracture and what are their indications. OBJECTIVE: To assess clinical outcomes of surgical treatments through anterior, posterior approaches, and anterior combined with posterior approach for lumbar vertebrae burst fractures. METHODS: A total of 79 patients with lumbar burst fractures were treated by operation. Different approaches were selected according to conditions of injury: posterior approach (57 patients), anterior approach (12 patients), and anterior combined with posterior approach (10 patients). ASIA was used to assess the recovery of neurological function before and after treatment. Cobb angle, correction loss of Cobb angle, bone fusion rate, failure rate of internal fixation, operative time and intraoperative bleeding loss were observed before and after treatment. RESULTS AND CONCLUSION: All 79 patients were followed up for at least 19 months. Except no changes in the 5 complete paralysis cases, the ASIA classification of postoperative nerve function in 63 incomplete paralysis cases was improved by 1 grade or more. ASIA grade and the Cobb angle were obviously improved after operation, showing significant differences between preoperation and last follow-up (P < 0.05). The Cobb angle correction loss in patients with posterior approach was significantly larger than those with anterior approach and anterior combined with posterior approach (P < 0.05). Operative time and blood loss were significantly less in posterior approach compared with anterior approach and anterior combined with posterior approach (P < 0.05). Five cases with posterior approach suffered from screw breakage. There were no significant differences in the rate of bone fusion and postoperative neurological function recovery in three approaches (P > 0.05). Results suggested that the three surgical approaches can effectively treat lumbar burst fractures, and can achieve satisfactory clinical outcomes. Posterior approach easily affected fixation breakage and postoperative correlation loss. Anterior approach and anterior combined with posterior approach obtained less correlation loss. The surgeons should choose the surgical approach according to the characteristics of patients, and aim to achieve the best clinical outcomes. © 2014 Journal of Clinical Rehabilitative Tissue Engineering Research.
