BACKGROUND The sensorimotor influence of the lateral ankle ligaments in muscle activation is unclear. HYPOTHESIS The lateral ankle ligaments have significant sensorimotor influence on muscle activation. STUDY DESIGN Controlled laboratory study. METHODS Muscle-firing characteristics in response to a high-speed inversion perturbation and during gait were assessed in 13 normal subjects. Solu...

OBJECTIVE The posterosuperior shoulder access used in surgical treatment for acromioclavicular dislocation was constructed through dissection of 20 shoulders from 10 recently chilled adult cadavers, and the distances from this route to the nearby neurovascular structures were analyzed. METHODS A Kirschner wire was introduced into the top of the base of the coracoid process through the postero...

OBJECTIVE There has been no uniformity of opinion concerning the structures supporting the female urethra. Therefore, the aims of this prospective study were to define precisely the female urethral support structures at cadaveric anatomic dissection and histologic examination and to determine which of these structures can be detected on MRI of cadaveric specimens and of healthy volunteers. SU...

BACKGROUND CONTEXT Most previous studies have investigated ligament mechanical properties at slow elongation rates of less than 25 mm/s. PURPOSE To determine the tensile mechanical properties, at a fast elongation rate, of intact human cervical anterior and posterior longitudinal, capsular, and interspinous and supraspinous ligaments, middle-third disc, and ligamentum flavum. STUDY DESIGN/S...

The forces induced in tiny wrist joint ligaments must be estimated in order to understand their role in the mechanism of the joint. We estimated forces in a number of selected ligaments in seven human wrist joint specimens, using a noninvasive method. The method is based on the rationale that the force generated in a ligament depends on its change of length with the joint under load. In vitro l...

Full-thickness burns around the knee joint are usually associated with exposure of bone, tendon or ligaments. Following excision of the deep burns, there is no viable wound bed to which skin grafts can be applied. Although vacuum-assisted closure has been used to encourage granulation tissue, exposure of the tendons and ligaments following excision usually requires muscle flaps or fasciocutaneo...

Ligaments and tendons are dense connective tissues that are important in transmitting forces and facilitate joint articulation in the musculoskeletal system. Their injury frequency is high especially for those that are functional important, like the anterior cruciate ligament (ACL) and medial collateral ligament (MCL) of the knee as well as the glenohumeral ligaments and the rotator cuff tendon...
