Carpal kinematics after proximal row carpectomy.
PURPOSE Proximal row carpectomy (PRC) is a clinically useful motion-sparing procedure for the treatment of certain degenerative conditions of the wrist. Clinical outcome studies after PRC have shown that wrist flexion-extension averages approximately 60% of that of the contralateral wrist. The purpose of this study was to determine how the kinematics of the wrist are altered after PRC. METHOD...
متن کاملWrist ligaments: their significance in carpal instability.
BACKGROUND Understanding the exact contribution of the supporting ligaments to the functional integrity of the wrist is crucial for the diagnosis and treatment of carpal instabilities. The present study evaluates functional significance of the wrist ligaments with respect to carpal instabilities. MATERIALS AND METHODS Sixteen fresh cadaver wrists were dissected. Extrinsic and intrinsic ligame...
متن کاملProximal Row Carpectomy
Excision of the proximal carpal row has proven over the past 60 years to be an effective technique for certain disorders of the wrist, including degenerative sequelae of scapholunate ligament dissociation and scaphoid nonunions, Kienböck disease, Preisser disease, and other fracture-dislocations of the wrist. The durability of this procedure may be due to remodeling of the capitate head to the ...
متن کاملSome biomechanical aspects of the carpal tunnel.
Previously presented evidence indicates that carpal tunnel syndrome is related to compression of the median nerve inside the carpal tunnel. Biomechanical arguments in which the extrinsic finger flexor tendons inside the carpal tunnel are characterized as a frictionless pulley-belt mechanism are presented to show quantitatively how wrist size, wrist position and hand position affect forces on th...
متن کاملMaterial properties of periodontal ligaments.
The mechanism of orthodontic teeth movement is not entirely explained. The principal reaction on tissues at the cellular and molecular level is initiated by the force applied to the tooth crown and transferred in turn upon the periodontal ligament (PDL). It seems, therefore, that the PDL and particularly its properties play a key role in bone remodelling. One of the more commonly used methods, ...
