This report describes the diagnosis and management of repetitive stress-related injury (RSRI) of the proximal metacarpus in a seven-year old Thoroughbred racehorse. Intra-articular analgesia of the middle carpal joint (MCJ) as well as perineural analgesia of the lateral palmar nerve (LPN) abolished lameness and a diagnosis of RSRI of the proximopalmar metacarpus was made after nuclear scintigra...

Rock climbers' grip techniques may result in a variety of hand injuries. Minor injuries such as soft-tissue damage, flexor tendon strain, tendinitis or tenosynovitis, joint contractures, and carpal tunnel syndrome may be treated by a primary care physician. Patients who have pulley ruptures should be referred if there is any uncertainty about the diagnosis. Because of controversies regarding su...

OBJECTIVE To compare two transient models of synovitis-osteoarthritis (OA) in horses by characterizing biological changes in synovial fluid and joint tissue. METHOD Twelve skeletally mature mares were utilized in a block design. Synovitis was induced by an intra-articular injection of 100 ng recombinant equine interleukin 1 beta (reIL-1β) or 0.5 ng lipopolysaccharide (LPS) into a middle carpa...

The manipulation mechanism of the giant panda (Ailuropida melanoleuca) was examined by means of CT (computed tomography) and 3-dimensional (3-D) Volume Rendering techniques. In the 3-D images of the giant panda hand, not only the bones but also the muscular system was visualised. Sections of the articulated skeleton were obtained. It was demonstrated that the hand of the panda is equipped with ...

Goals of reducing wrist pain, allowing a stable active wrist range of motion, and retarding degenerative changes make arthrodesis of the scapho-trapezio-trapezoid joint a popular treatment for chronic static and dynamic scapho-lunate instability; however, pitfalls and complications have not been well studied. Forty-seven wrists in 46 patients over a 10-year period revealed a complication rate o...

We report a case of acute carpal tunnel syndrome caused by periarticular calcification (hydroxyapatite deposition disease) around the wrist joint in a 64-year-old woman. She had acute severe pain, exacerbated by wrist movements and extension of the fingers. Her full blood count, urea, electrolytes, uric acid, calcium, phosphate, alkaline phosphatase, and thyroid function levels were all within ...

To identify a safe entry point for needle insertion in patients with idiopathic carpal tunnel syndrome (CTS), cross-sectional images of the wrist MRI of 45 normal volunteers and 180 consecutive patients with idiopathic CTS were reviewed. Insertion of the needle from the five different entry points into the carpal tunnel was simulated by drawing a 1-pixel line, and the incidence of contact with ...

Computer assisted surgical interventions and research in joint kinematics rely heavily on the accurate registration of three-dimensional bone surface models reconstructed from various imaging technologies. Anomalous results were seen in a kinematic study of carpal bones using a principal axes alignment approach for the registration. The study was repeated using an iterative closest point algori...
