Scapholunate Instability: Current Concepts in Diagnosis and Management
نویسنده
چکیده
Injuries to the scapholunate joint [SLJ] are the most frequent cause of carpal instability and account for a considerable degree of wrist dysfunction. It is insufficient to cause abnormal carpal posture or collapse on static radiographs, an isolated injury to the scapholunate interosseous ligament may cause progression to abnormal joint mechanics, cartilage wear, and degenerative changes. Intervention for scapholunate instability is aimed at arresting the degenerative process by restoring ligament continuity and normalizing carpal kinematics.

Scapholunate instability: current concepts in diagnosis and management.
Injuries to the scapholunate joint are the most frequent cause of carpal instability and account for a considerable degree of wrist dysfunction, lost time from work, and interference with activities. The complex arrangement and kinematics of the 2 rows of carpal bones allows for an enormous degree of physiologic motion, and a hierarchy of primary and secondary ligaments serves to balance an inh...
متن کاملBeware the sprained wrist. The incidence and diagnosis of scapholunate instability.
A consecutive series of 100 cases of wrist injury, other than those referred with a radial fracture, have been reviewed to determine the incidence of acute scapholunate instability; a "clenched fist" radiograph was used in addition to the routine scaphoid views. Of 19 patients with an increase in the scapholunate gap, five were eventually considered to have significant scapholunate instability,...
متن کاملProposition of a new classification for scapholunate instability.
UNLABELLED Scapholunate (SL) instability is the most common pattern of instabilities in the wrist. If untreated or undiagnosed, it may lead to degenerative changes with SLAC (scapholunate advanced collapse) wrist. There are a few of of well-known SL instability classifications. The one that takes into account a dynamic or static nature of SL instability is the most accepted and used. The arthro...
متن کاملDorsal wrist capsular tears in association with scapholunate instability: results of an arthroscopic dorsal capsuloplasty.
Purpose The purpose of this study is to report the association of dorsal wrist capsular avulsion with scapholunate ligament instability and to evaluate the results of an arthroscopy-assisted repair. Methods We retrospectively reviewed 10 patients with a mean age of 39.1 years suffering from chronic dorsal wrist pain. They underwent a wrist arthroscopy with an evaluation of the scapholunate liga...
متن کاملBlatt's capsulodesis for chronic scapholunate instability.
Nineteen patients underwent a scapholunate interosseous ligament repair combined with a Blatt's capsulodesis for scapholunate instability between 1994 and 1999. The diagnosis was based on clinical, radiographic and arthroscopic assessments. Mean follow-up was 22 months (range: 8 months to 5 years). Fifteen patients were available for follow-up. Most (13 of 15) of the patients presented with pre...
