BACKGROUND Failed shoulder instability surgery is mostly considered to be the recurrence of shoulder dislocation but subluxation, painful or non-reliable shoulder are also reasons for patient dissatisfaction and should be considered in the notion. METHODS The authors performed a revision of the literature and online contents on evaluation and management of failed shoulder instability surgery....

stafne bone defect is a bone depression containing salivary gland or fatty soft tissue on the lingual surface of the mandible. the most common location is within the submandibular gland fossa and often close to the inferior border of the mandible. this defect is asymptomatic and generally discovered only incidentally during radiographic examination of the area. stafne bone defect appears as a w...

OBJECTIVE To compare, in terms of their demonstration of tears of the anterior glenoid labrum, oblique axial MR arthrography obtained with the patient's shoulder in the abduction and external rotation (ABER) position, with conventional axial MR arthrography obtained with the patient's arm in the neutral position. MATERIALS AND METHODS MR arthrography of the shoulder, including additional obli...

Objective- To evaluate the role of greater omentum incorporation of coral in healing of the long bone defect in dog model. Design- Experimental in-vivo study. Animals- Sixteen adult mongrel male dogs weighing 26.2±2.5 kg, free of evident infectious or parasitic illnesses were used in this study. Procedures- The operative procedure was undertaken under general anesthesia. Radial bone was expo...

BACKGROUND Current knowledge is lacking concerning the appropriate site of osteochondral allograft harvest to match glenoid shape for the purposes of glenoid resurfacing. This has led to difficulty with adequate restoration of the geometry of the glenoid with currently available techniques. HYPOTHESIS The medial tibial plateau will provide a suitable osteochondral harvest site because of its ...

OBJECTIVE The objective of the present study was to develop a numerical model of the shoulder able to quantify the influence of the shape of the humeral head on the stress distribution in the scapula. The subsequent objective was to apply the model to the comparison of the biomechanics of a normal shoulder (free of pathologies) and an osteoarthritic shoulder presenting primary degenerative dise...

BACKGROUND Baseplate micromotion of the reverse shoulder glenoid component can lead to implant loosening. We hypothesized that a remotely positioned displacement gage measures elastic deformation of the system rather than actual micromotion at the implant/bone interface. METHODS Reverse glenoid components were implanted into polyurethane blocks of 3 different densities. A 700 N compressive lo...

We report 127 cases who have had elective operation on cranium because of skull bone defect during 1984-1989. Usually repair of skull bone defect and preserving normal anatomy were the major therapeutic goals. 10, II In these cases a new surgical technique is described which can successfully accomplish these goals in a single but staged operative procedure.

Osteoarthritis results in changes in the dimensions of the glenoid. This study aimed to assess the size and radius of curvature of arthritic glenoids. A total of 145 CT scans were analysed, performed as part of routine pre-operative assessment before total shoulder replacement in 91 women and 54 men. Only patients with primary osteoarthritis and a concentric glenoid were included in the study. ...
