METHODS： Literature search was performed of PubMed and Cochrane Library by two independent authors to identify randomized controlled trials （RCTs） comparing operative vs nonoperative treatment of DIACF from inception to December 31st, 2013. RCT quality was evaluated by the modified Jadad scale. Dichotomous variables were pooled using risk ratios by review manager 5.3 software. Fixed-effects or random-effects models were adopted with P 〉 0.05 or P ≤ 0.05 for heterogeneity tests, respectively.RESULTS： Eight RCTs comprising 767 cases met inclusion criteria. Results revealed that more surgically treated patients could resume pre-injury job （P = 0.006）. No statistical differences were found between the two groups in residual pain （P = 0.33）, shoe fitting problems （P = 0.07）, limited walking distance （P = 0.56） or secondary late arthrodesis （P = 0.38）. However, operative treatment was associated with a higher complication rate （P = 0.003）. Subgroup analyses of specific complications revealed that except for a higher risk of superficial wound problems （P 〈 0.0001） in operative group, the two groups had similar complication rate in deep wound infection （ P = 0.34）,CONCLUSION： Current evidence demonstrates that compared with operative treatment, conservative treatment of DIACF lead to similar clinical outcomes regarding residual pain, shoe fitting, walking distance and secondary subtalar arthrodesis but a significantly lower complication rate.展开更多

While there are various treatment options for displaced tibial plateau fractures, the standard of care is open reduction and internal fixation(ORIF). In physiologically young patients with higher demand and better bone quality, ORIF is the preferred method of treating these fractures. However, future total knee arthroplasty(TKA) is a consideration in these patients as post-traumatic osteoarthritis is a common long-term complication of tibial plateau fractures. In older, lower demand patients, ORIF is potentially less favorable for a variety of reasons, namely fixation failure and the need for delayed weight bearing. In some of these patients, TKA can be considered as primary mode of treatment. This paper will review the literature surrounding TKA as both primary treatment and as a salvage measure in patients with fractures of the tibial plateau. The outcomes, complications, techniques and surgical challenges are also discussed.展开更多

The purpose of this study is to investigate the clinical and radiographic outcomes of comminuted intra-articular DRFs treated with a dynamic external fixator combined with a volar locking plate (VLP). Methods: Eleven patients (mean age, 61 years) with comminuted intra-articular DRFs were treated with a dynamic type of external fixator combined with a VLP. Following reduction and fixation with a VLP, the dynamic external fixator was applied and the distal ball joint of the fixator was aligned with the lunate-capitate line. The ball joint was unlocked approximately 2 weeks after surgery to allow wrist mobilization. The fixator was removed 3 - 6 weeks (mean, 5 weeks) after surgery. Consequently, clinical and radiographic assessments were carried out at the final follow-up. Results: At the final follow-up, the mean range values of wrist extension and flexion were 76°and 64°, respectively. Compared with the contralateral side, the mean grip strength was 84%. The mean Modified Mayo Wrist Score and the Disabilities of the Arm, Shoulder and Hand score were 88 and 9, respectively. No significant differences in the radiographic parameters exist between after surgery and final follow-up. Conclusions: This study indicated that the dynamic wrist fixator combined with a VLP is effective for the treatment of AO type C3 DRFs.展开更多

Ideal treatment necessitates the restoration of a stable and congruent joint that will allow early mobilization. The purpose of this study was to investigate the results of intra-articular fracture of the fingers by mini external fixator combined with limited internal fixation. Methods From May 2005 to May 2007, a total of 26 patients with intra-articular fracture of the fingers were treated by mini external fixator combined with limited internal fixation. Of the 26 cases, 11 involved in metacarpophalangeal joint, and 15 interphalangeal joint in proximal interphalangeal. Kirschner wire, mini wire and absorbable suture were used for limited internal fixation. All patients were followed up and patients were accomplished with total active motion （TAM） of fingers. Results All patients were reviewed by an independent observer. The mean follow up was 13 months （range 9 to 24 months）. Subjective, objective and radiographic results were evaluated. X-ray films revealed fracture union and the average radiographic union time was 7 weeks with a range of 5-12 weeks and the phalange shortening or rotation in 2 cases, joint incongruity （less than 1 mm） and joint space narrowing in 3 cases respectively. Phalangeal shortening or rotation was observed in 2 cases and joint incongruity or joint space narrowing was observed in 3 cases. An artificial implant was performed on one case for traumatic arthritis 1.5 years after surgery. Based on TAM the overall good-excellent rate of joint motion function was 80.8%. Conclusion Mini external fixator combined with limited internal fixation is a reliable and effective method for treatment of intra-articular fracture of the fingers.展开更多

Vertebroplasty and kyphoplasty are palliative augmentation procedures that have been associated with increased risks of cement leakage, adjacent fractures and non-union. Objective: The aim of this study was to describe a novel approach for the union of osteoporotic vertebral compression fractures with minimally invasive open reduction and internal fixation. Patients and Methods: Seven consecutive patients with intractable back pain without neurological deficits due to osteoporotic vertebral compression fractures were treated using minimally invasive fixation with intra-vertebral expandable pillars and artificial bone substitute. The clinical symptoms and image findings were recorded. Results: All of the patients reported relief of back pain, and the height of the vertebral bodies was well restored. X-ray findings obtained 2 to 4 years after the procedures showed fracture healing and favorable formation of the callus confirmed in the anterior longitudinal ligament. Conclusion: This mini-open procedure with intravertebral devices is an effective and reliable technique for osteoporotic vertebral compression fractures and may avoid complications related to traditional open spinal instrumentation procedures and augmentation with bone cement.展开更多

However, they do suggest a higher rate of reoperations in those receiving internal fixation compared with arthroplasty. Differing patient characteristics at baseline make direct comparisons difficult.展开更多

Conclusion Thus restoration of articular congruency and alignment is possible with minimal complication using modern non-angular stable methods of internal fixation.展开更多
