This review describes a series of experiments in which sarcomere length was measured in human wrist muscles to understand their design. Sarcomere length measurements were combined with studies on cadaveric extremities to generate biomechanical models of human wrist function and to provide insights into the mechanism by which wrist strength balance is achieved. Intraoperative measurements of the...

The present study investigated the effects of grip on changes in the median nerve cross-sectional area (MNCSA) and median nerve diameter in the radial-ulnar direction (D1) and dorsal-palmar direction (D2) at three wrist angles. Twenty-nine healthy participants (19 men [mean age, 24.2 ± 1.6 years]; 10 women [mean age, 24.0 ± 1.6 years]) were recruited. The median nerve was examined at the proxim...

Purpose: Root fracture is a clinical problem which often is difficult to detect and diagnose. As the root fracture detection is based on demonstration of a fracture line or lines, radiographic examination is important. The aim of this study was to compare diagnostic efficacy of direct digital radiography with conventional radiography for detecting experimental root fractures. Materials & Method...

background:  new discoveries about the pathophysiology changed the concept that all forms of osteoarthritis are alike; this lead to the delineation of different phenotypes such as age, trauma or obese related forms. we aim to compare soluble mediator profiles in primary knee and posttraumatic wrist osteoarthritis. based on the general faster progression rate of wrist osteoarthritis, we hypothes...

background : the hand and wrist bones are infrequent sites for osteoid osteoma, and its diagnosis can be difficult. this paper reports 25 cases of osteoid osteoma in the hand and wrist.   methods : records of the 25 patients who had pathological conditions of osteoid osteoma of the hand and wrist were reviewed and analyzed.   results : twenty-five cases of osteoid osteoma of the hand and wrist ...

To increase in vivo tendon force and gliding after flexor tendon repair, a variety of modifications to the methods by which protective passive motion is administered have been advocated. To determine the relationship between the prime variables, wrist and digital position, muscle activation, and in vivo tendon force, a clinically relevant canine model was developed. Force was measured in the fl...
