The effect of the three-ligament tenodesis on the scapholunate angle and scapholunate gap was studied. A comparison was made between these angles preoperatively and postoperatively in 12 patients. There was a significant decrease in the scapholunate angle from 77 to 68 degrees, and the scapholunate gap was reduced from 4.25 mm to 3.29 mm. We also studied the correlation between scapholunate ang...

Background Treating chronic scapholunate ligament injuries without the presence of arthritis remains an unsolved clinical problem facing wrist surgeons. This article highlights a technique for reconstructing the scapholunate ligament using novel fixation, the ScaphoLunate Axis Method (SLAM). Materials and Methods In a preliminary review of the early experience of this technique, 13 patients wer...

Background Untreated scapholunate ligament disruption may lead to progressive wrist arthritis. Current techniques used to treat the disruption may not prevent arthritis because of attenuation of a reconstructive ligament substitute or failure to re-establish normal wrist kinematics. Questions/Purposes This study evaluates a combined synthetic-autologous technique for the treatment of scapholuna...

Repair of the volar scapholunate ligament has not been performed arthroscopically. We present an all-inside technique that presents closure of the anterior scapholunate interval. A Tuohy needle and a resorbable suture are all that is required.

Five cases of scapholunate instability are reported. The condition is commonly misdiagnosed in accident and emergency departments. The importance of a complete clinical assessment of the suspected scaphoid injury and the need to measure the scapholunate distance and the scapholunate angle on the radiographs is stressed.

Seven patients with chronic scapholunate instability (Geissler grade 2-4) were treated by percutaneous placement of screws across the scapholunate joint after arthroscopic debridement of the remnants of the scapholunate ligament. In all seven cases, the screw caused partial destruction of the lunate and/or scaphoid requiring screw removal within 6 months. We no longer perform this procedure.

PURPOSE As long as the neuromuscular stabilizers are intact, a lesion of the scapholunate ligament may or may not progress to a carpal instability. The mechanisms by which the muscles compensate this defect are not very well known. We designed an experimental study with the aim of clarifying these mechanisms. MATERIAL AND METHOD Using 10 fresh wrists, with no pre-existing lesions, we studied ...

OBJECTIVE Closed reduction and internal fixation of the scapholunate dissociation are currently performed using K-wires or a headless bone screw. We present an alternative for this fixation by means of a cannulated screw with dynamic adjustable interfragmentary compression and discuss the advantages of using this type of technique. METHODS Closed reduction of the scapholunate interval was ach...

BACKGROUND Soft-tissue injuries of the wrist are often not recognized in patients with distal radial fractures, yet scapholunate injuries have been reported to occur in association with as many as 54% of distal radial fractures. The true prevalence and natural history of intercarpal ligament injury are not known. METHODS This prospective observational study assessed the prevalence and one-yea...

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...
