Methods 12 cases of acute acromioclavicular joint dislocations were treated and followed. Results 11 cases succeeded and one failed with technical mistakes. Conclusion Because no important nerve or vessel passing between coracoid process and clavicle, close reduction and percutaneous coracoclavicular cannulated lag screw fixation treatment is safe, effective and affords early rehabilitation.展开更多

Material and Methods: 54 patients with isolated lateral malleolus fractures treated between March 2012 and April 2015 at Fatih Sultan Mehmet Training and Research Hospital were evaluated with the Ankle-Hindfoot Scale of the American Orthopedic Foot and Ankle Society (AOFAS) score (excellent, ≥90;good, 75 - 89;acceptable, 50 - 74;poor, Results: There was no significant change in AOFAS, VAS, PSS and the union rates between two plating techniques. Conclusion: Similar results have shown both of two plating techniques were successful treating isolated lateral malleolus fracture.展开更多

The combination of symphyseal and parasymphyseal fracturesrepresent 47.09% of the total mandibular fractures.AIMTo compare the effectiveness of lag screws vs double Y-shaped miniplates in thefixation of anterior mandibular fractures.METHODSThis study is a prospective randomized controlled clinical trial, performed onsixteen patients with anterior mandibular fractures. Patients were divided equallyinto two groups, each consisting of eight patients. Group 1: Underwent openreduction and internal fixation using two lag screws. Group 2: Underwent openreduction and internal fixation using double Y-shaped plates. The followingparameters were assessed: operating time in minutes, pain using a visual analogscale, edema, surgical wound healing for signs and symptoms of infection,occlusion status and stability, maximal mouth opening, and sensory nervefunction. Cone beam computed tomography was performed at 3 and 6 mo tomeasure bone density and assess the progression of fracture healing.RESULTSThe study included 13 males (81.3%) and 3 females (18.8%) aged 26 to 45 years(mean age was 35.69 ± 6.01 years). The cause of trauma was road traffic accidentsin 10 patients (62.5%), interpersonal violence in 3 patients (18.8%) and othercauses in 3 patients (18.8%). The fractures comprised 10 parasymphyseal fractures(62.5%) and 6 symphyseal fractures (37.5%). The values of all parameters were comparable in both groups with no statistically significant difference except forthe mean bone density at 3 mo postoperatively which was 946.38 ± 66.29 in group 1 and 830.36 ± 95.53 in group 2 (P = 0.015).CONCLUSIONBoth lag screws and double Y-shaped miniplates provide favorable means offixation for mandibular fractures in the anterior region. Fractures fixed with lagscrews show greater mean bone density at 3 mo post-operation, indicative ofhigher primary stability and faster early bone healing. Further studies with largersample sizes are required to verify these conclusions.展开更多
