A seven-month-old cat was referred, after having been missing for one week, for evaluation and treatment of a right forelimb injury and facial fractures. On physical examination, a moderate partial weight-bearing lameness of the right forelimb was present, with palpable crepitus in the glenohumeral joint. Dental radiographs revealed a midline palatal fracture and rostral fractures of the left m...

Fractures of the scapula occur mainly from direct trauma involving considerable violence and associated injuries of the shoulder and thorax are common. In most cases early functional treatment gives good or excellent results. Operative treatment may, however, be indicated, especially with displaced intra-articular fractures, fractures of the glenoid rim associated with humeral head subluxation,...

CONTEXT Osseous injury to the glenoid is increasingly being recognized as one of the most important aspects in the successful management of recurrent shoulder instability. Proper early recognition of glenoid bone injury in the setting of recurrent instability will lead to successful nonoperative and operative decision making, particularly in the athletic patient. EVIDENCE ACQUISITION We condu...

In children with brachial plexus birth palsy, the unopposed contraction of the shoulder internal rotators and adductors, secondary to weakness of the external rotators and abductors, leads to internal rotation contracture of the shoulder joint. Latissimus dorsi and/or teres major tendon transfers combined with open musculotendinous lengthening can improve shoulder function. Arthroscopic release...

The central importance of BMP signaling in the development and homeostasis of synovial joint of appendicular skeleton has been well documented, but its role in the development of temporomandibular joint (TMJ), also classified as a synovial joint, remains completely unknown. In this study, we investigated the function of BMPRIA mediated signaling in TMJ development in mice by transgenic loss-of-...

OBJECTIVE To evaluate the analgesic effectiveness of intra-articular botulinum toxin Type B (BoNT/B) in a murine model of chronic degenerative arthritis pain. METHODS AND MATERIALS Chronic arthritis was produced in adult C57Bl6 mice by intra-articular injection of Type IV collagenase into the left knee. Following induction of arthritis, the treatment group received intra-articular BoNT/B. Art...

This annotation considers the place of extra-articular reconstruction in the treatment of anterior cruciate ligament (ACL) deficiency. Extra-articular reconstruction has been employed over the last century to address ACL deficiency. However, the technique has not gained favour, primarily due to residual instability and the subsequent development of degenerative changes in the lateral compartmen...

       Background: An intra-articular distal humerus malunion can be disabling. To improve function, reduce pain and/ or prevent further secondary osteoarthritis an intra-articular corrective osteotomy can be considered. Herein we present the indications, practical guidelines for pre- operative planning and surgical technique. Subsequently, we provide long-term results in a small series.   Meth...
