PURPOSE This study was conducted to compare the time-course changes in condylar long-axis and skeletal stability after sagittal split ramus osteotomy (SSRO) with bicortical plate fixation versus monocortical plate fixation. PATIENTS AND METHODS Of a group of 40 Japanese patients diagnosed with mandibular prognathism, 20 underwent SSRO with bicortical plate fixation using a locking plate syste...

Military service members have increased requirements of shoulder weight bearing to perform duties. Operative intervention has increased for treatment of displaced middle one-third clavicle fractures. Complications of operatively treated clavicle fixation have not been extensively studied. A retrospective, longitudinal cohort chart evaluation was conducted of all active duty members undergoing f...

Background:   To compare the results of two different ways of distal femoral osteotomy stabilization in patients suffering from genuvalgum: internal fixation with plate, and casting. Methods:   In a non-randomized prospective study, after distal femoral osteotomy with the zigzag method, patients were divided into two groups: long leg casting, and internal fixation with blade plate. For all pati...

This study aimed at comparing the results of clavicular fracture fixation with AO Reconstruction (Recon) plate and Dynamic Compression Plate (DCP). The case notes of 39 patients with 40 acute and chronic clavicular fractures were retrospectively reviewed. The indications for fixation for acute cases comprised open fractures, the presence of sufficient skin tenting to risk skin integrity, neurov...

Objective The authors prospectively analyzed the effect of one-level or two-level anterior cervical discectomy and fusion (ACDF), comparing stand-alone cages and cage-with-plate fixation constructs with respect to clinical outcomes and radiologic changes. Methods A total of 84 patients who underwent one-level (n=52) or two-level ACDF (n=32) for cervical disc disease and who completed 2 years ...

AO clavicular hook plate fixation provides more rigid fixation and good bony union rates for Neer type II distal clavicular fractures. However, the hook may cause rotator cuff tears and subacromial impingement, which adversely affect the clinical results. T-plate fixation is another surgical method of treatment for unstable clavicle fractures, and its clinical efficacy has been demonstrated. Th...

PURPOSE The purpose of this study is to compare the stress and stability of plate-screw fixation and screw fixation in the treatment of Schatzker type IV medial tibial plateau fracture. METHODS A three-dimensional (3D) finite element model of the medial tibial plateau fracture (Schatzker type IV fracture) was created. An axial force of 2500 N with a distribution of 60% to the medial compartme...

BACKGROUND Plate fixation is the most commonly used technique for the treatment of shaft fractures of both forearm bones (SFBFBs). However, all fractures are difficult to treat with plate fixation because of soft tissue injuries, fracture patterns, or the patient's condition. The purpose of this study is to compare the functional results of plate fixation only and combined plate and intramedull...

Osteoporotic bone with poor mechanical capacity provides limited stability after fixation of ankle fractures. Stabilization with an implant providing increased fixation strength in osteoporotic bone could reduce failure rates of fixation and allow a more functional treatment. The purpose of this study was to evaluate a locking contoured plate for fixation of distal fibular fractures in comparis...

Objective The objective of this study was to compare the relative stability in lumbar spondylolysis (SP) of a rigid anterior plate (with a novel compression slot) versus traditional posterior pedicle screw (PS) fixation. Summary of Background Data Arthrodesis has been a mainstay of treatment for symptomatic isthmic spondylolisthesis in adults. Posterior PS fixation has become a commonly used ad...
