Objective: The purpose of this study was to evaluate both clinically and radiographically using of two microplates in treatment of displaced pediatric mandibular fractures.Materials & methods: This study included ten children had displaced mandibular fracture with age ranged between (4e11) years were treated using two microplates and microscrews through intraoral approach. All children were examined preoperative clinically and radiographically by panoramic view and computed tomography (CT) or lower occlusal view. All children were evaluated postoperative clinically at one week, one and three months for wound healing, occlusion, infection, nerve affection and stability of fracture and radiographically by panoramic view at second postoperative day, one and three months and by quantitative CT at one and three months to evaluate the accuracy of reduction and bone healing at fracture line. Results: Clinically there were no complications in all cases overall follow up period except for two cases showing occlusal discrepancy treated with guiding elastics. Radiographic results showed that good alignment of fracture segments horizontally and vertically without displacement and significant increase in bone mineral density gain after one and three months. Conclusion: Titanium microplates provide adequate stability for fracture segments in treatment of pediatric mandibular fracture. Low profile and malleability of microplates allow adaptation to mandible easily and minimize the possibility of trauma to teeth buds.

Purpose: This study aimed to compare the use of interpositional bovine bone block to autogenous chin bone block in augmentation of atrophic posterior mandible for dental implant installation. Materials and Methods:Twelve patients (n=12) with atrophic posterior mandible were augmented using inlay technique and divided randomly into two equal groups according to the type of the graft used, autogenous bone graft (Group I) and bovine bone graft (group II). After six months, core biopsies sites were taken from the sites of implant, which were analyzed histologically.Results: Six months after augmentation, alveolar bone height gain were 10.76 ± 1.043 mm and 11.24 ± 0.3721 mm for group I and group II respectively. There was no statistical significant difference in height gain between both groups as p > 0.05. There was more graft remnants in bovine group, but both groups showed a good level of osteointegration with an adequate extension of bonding surface between host bone and the graft particles. Conclusion:Both grafts achieved successful results, however the use of the bovine bone graft was less invasive and avoided donor site morbidity.

Background: Intercondylar fracture humerus needs early treatment, anatomical reduction, rigid fixation and early ROM. This study hypothesized that Intercondylar fracture humerus better approached by olecranon osteotomy for comminuted types & by triceps anconeus sparring for simple two parts intercondylar fracture humerus. Aim of Work: Is to compare classic olecranon osteotomy approach with triceps anconeus sparing approach (TRAP) in open reduction and internal fixation of intercondylar fracture humerus patients; regarding exposure of fracture site, operative time, post-operative pain, union time, return to pre fracture range of motion of elbow joint and complications rate. Comparing our results to the published series in the literatures. Patients and Methods: A clinical study was conducted From January 2012 to October 2015. In this study, forty patients with intercondylar fracture humerus were treated by ORIF using triceps anconeus sparing and olecranon osteotomy approaches. Age ranges from 25 to 60 years. Elbow mayo score and muscle power used for scoring & follow-up period 6 months. Results: All patients were evaluated pre-operatively and post-operatively for Elbow mayo function score, wolf law for triceps power were completed at 1, 3 & 6 months. Olecranon osteotomy gave better results in comminuted intercondylar fractures but triceps sparring was better in simple two part intercondylar humerus fractures especially in young patients.
