PURPOSE The study was conducted to compare the radiographic and clinical methods of measuring the horizontal condylar guidance (HCG) values. MATERIALS AND METHODS The condylar guidance was measured using the radiographic (CT scan) and three clinical methods i.e. the wax protrusive records, Lucia jig record and intraoral central bearing device in 12 patients aged between 20-40 years irrespecti...

abstract   background: different methods of surgical treatment for acromioclavicular(ac) joint injury were considered in the literature. the purpose of the study was to compare intra- articular ac repair technique with the extra-articular coracoclavicular repair technique for the patients with rockwood type iii and vac joint injury when indicated.   methods: nineteen consecutive patients with r...

PURPOSE To introduce a new approach to reconstruct a 3D model of the TMJ using magnetic resonance imaging (MRI) and cone-beam computed tomography (CBCT) registered images, and to evaluate the intra-examiner reproducibility values of reconstructing the 3D models of the TMJ. METHODS MRI and CBCT images of five patients (10 TMJs) were obtained. Multiple MRIs and CBCT images were registered using...

BACKGROUND The delayed management of patients with shoulder instability may increase the prevalence and severity of concomitant intra-articular shoulder injuries resulting from persistent subluxations and dislocations. HYPOTHESIS Patients with a longer delay from the initial dislocation event to undergoing magnetic resonance imaging (MRI) or magnetic resonance arthrography will demonstrate mo...

The generally-accepted treatment for large, displaced fractures of the glenoid associated with traumatic anterior dislocation of the shoulder is operative repair. In this study, 14 consecutive patients with large (> 5 mm), displaced (> 2 mm) anteroinferior glenoid rim fractures were treated non-operatively if post-reduction radiographs showed a centred glenohumeral joint. After a mean follow-up...

intraepiphyseal location of an osteoid osteoma is extremely rare with few cases reported in the literature. they are often present with various atypical and nonspecific clinical features. synovitis of adjacent joint is common and along with chronic inflammation could be misinterpreted as rheumatoid arthritis. initial plain radiographs are often not diagnostic and further radiologic evaluation w...

Arthroscopy is commonly used for evaluating intra-articular fracture patterns and assessing postfixation reduction; however, the use of arthroscopy for the definitive treatment of articular fracture nonunion has not been reported. This article describes a case of symptomatic glenoid fossa fracture nonunion that was successfully treated with arthroscopically assisted percutaneous screw fixation ...

BACKGROUND Anterior shoulder instability associated with severe glenoid bone loss is rare, and little has been reported on this problem. Recent biomechanical and anatomical studies have suggested guidelines for bony reconstruction of the glenoid. HYPOTHESIS Anatomical glenoid reconstruction will restore stability in shoulders with recurrent anterior instability owing to glenoid bone loss. S...

INTRODUCTION The spectrum of pathoanatomic lesions encountered in anterior shoulder dislocation is broad. There could be a presence of loose bodies, chondral and osteochondral, in the shoulder joint and also concomitant rotator cuff partial tears resulting from acute and chronic shoulder instability. CASE REPORT We present one case report of a 46-year-old male Chinese with an uncommon case of...

In the rehabilitation of a patient with loss vertical dimension, repositioning condyle may be crucial to avoid loading on retrodiscal area temporomandibular joint (TMJ). However, establishing new position within glenoid cavity is not simple procedure, and several indications exist in literature. Digital techniques 3D visualization using cone beam computed tomography (CBCT) can help. this clinic...
