All-Dorsal Arthroscopic Ligamentoplasty (ADAL) in Scapholunate Instability Management: Surgical Technique

Abstract

In advanced scapholunate instability, a scapholunate repair by open or arthroscopic ligamentoplasty is indicated. Although the radiographic results and functional scores are more or less satisfactory for open ligamentoplasty, it is often responsible for a decrease in joint amplitude postoperatively. Arthroscopic techniques are therefore of great interest, since they respect the joint capsule, but they remain technically difficult and demanding surgeries, requiring a good deal of experience in arthroscopy and using bone tunnels that are potentially a source of complications, as well as pinning to the palmar side of the wrist, which is potentially dangerous for the palmar structures of the wrist. We present a surgical technique of scapholunate ligamentoplasty under arthroscopy, focusing only on the dorsal scapholunate complex: all-dorsal arthroscopic ligamentoplasty. The advantages of all-dorsal arthroscopic ligamentoplasty are that it requires little material, does away with palmar approaches, and focuses only on the dorsal side, simplifying surgery and avoiding the creation of bone tunnels potentially at risk of fracture or avascular necrosis.
