Abstract

Scapholunate interosseus ligament (SLIL) injury is a common wrist ligament injury causing stiffness and pain. If untreated, it can lead to wrist arthritis and carpal instability. Injuries often result from falling on an outstretched hand. Pre-dynamic and dynamic scapholunate instability are considered among the leading causes of wrist pain that might be clinically challenging to diagnose because the radiological findings are often not conclusive. Arthroscopic examination is now regarded as the gold standard for direct visualization of the SLIL
Aim:
We aimed to diagnose two types of SLIL instability, pre-dynamic and dynamic, using wrist arthroscopy, and study the correlation between findings of the wrist arthroscopy, radiological data, and clinical data.
Patients and Methods:
20 patients were admitted to El-Hadara University Hospital suffering from dorsal wrist pain and suspected to have SLIL instability after their evaluation radiologically and clinically using X-rays and (Magnetic Resonance Imaging) MRI. Arthroscopic diagnosis, injury staging, and management were applied to all patients based on the arthroscopic findings, Geissler, and European Wrist Arthroscopy Society (EWAS) classifications.
