BACKGROUND Superior dislocation of the patella is an uncommon condition that mainly occurs in knees with a high patella and medial femorotibial degenerative arthritis. There are no previous reports of this condition occurring in association with tibial valgus osteotomy. CASE REPORT We report the case of a patient in whom vertical dislocation recurred twice at 4 months after tibial valgus oste...

OBJECTIVE To determine whether training on shoulder and elbow surgery influences the orthopedist surgeons' preferred technique to address acute acromioclavicular joint dislocation (ACD). METHODS A survey was conducted with shoulder and elbow specialists and general orthopedists on their preferred technique to address acute ACD. RESULTS Thirty specialists and forty-five general orthopedists ...

Address for correspondence; Assoc Prof A-M Kelly Department of Emergency Medicine Western Hospital Private Bag, Footscray 3011 Email: [email protected] Introduction Anterior dislocation of the shoulder is the most common major joint dislocation encountered in emergency departments. Reduction of these dislocations is one of a range of procedures in which emergency physicians need to b...

Peroneal tendon dislocations are most prevalent in the active and athletic population, so accurate diagnosis and management are essential for optimal return of function. Although many nonoperative and surgical management options have been described, the optimal treatment method continues to be debated. In this technique article, a modified retromalleolar groove-deepening technique is described ...

A technique for generating spherically symmetric dislocation solutions of a direct Poincaré gauge theory of gravity based on homogeneous functions which makes Cartan torsion to vanish is presented.Static space supported dislocation and time dependent solutions are supplied.Photons move along geodesics in analogy to geodesics described by electrons around dislocations in solid state physics.Tach...

BACKGROUND This study was conducted to evaluate the functional outcome and MRI findings of arthrocentsis followed by autologous blood injection (ABI) into the joint space for management of chronic recurrent TMJ dislocation. MATERIAL AND METHODS Total ten patients with bilateral chronic recurrent condylar dislocation were included in the study. Arthrocentesis of both TMJ was performed on each ...

purpose: to report occurrence, management, and outcome of late-onset traumatic dislocation of laser in situ keratomileusis (lasik) flaps case report: we report a patient with late-onset lasik corneal flap dislocation after blunt ocular trauma occurring four years after surgery. an ultrasound biomicroscopy (ubm) was performed to view the status of flap and determination of flap thickness. result...

A procedure for line-shape analysis of broadened X-ray (or neutron) diffraction peaks is presented and specified for b.c.c. materials, which takes into account the effect of interfaces, internal stress of the 2nd kind and a dislocation distribution with weak defect correlation. Application of the technique is demonstrated by the estimation of dislocation densities in plastically deformed a-iron...

Ossicular injury is a frequent complication of head trauma and temporal bone fractures. An isolated fracture of the malleus with lateral dislocation of the manubrium is extremely rare. High-resolution computed tomography is the method of choice for evaluation of ossicular trauma. Virtual endoscopy (VE) is a novel technique that provides a realistic surface rendering of various organs that can b...

Chronic recurrent temporomandibular joint (TMJ) dislocation is defined as the complete loss of articular relationships, during mouth-wide opening, between the articular fossa of the temporal bone and the condyle-disk complex. The most frequent pathogenetic factors involved in chronic recurrent dislocation of the TMJ are supposed to be trauma, abnormal chewing movements, TMJ ligaments, capsule l...
