Osteolysis After Augmented Scapholunate Ligament Reconstruction: A Report of 3 Cases

CASE

Augmented scapholunate ligament reconstruction using polyether ether ketone anchors and ultra-high molecular weight polyethylene synthetic tape has the theoretical advantage of improved stability, avoidance of K-wire fixation, and the potential for earlier mobilization. We present 3 cases of scaphoid and lunate osteolysis/fragmentation, operative and histologic findings at reoperation, and the sequelae of this technique.

CONCLUSION

If planning to use suture anchors and synthetic tapes in small carpal bones, we recommend advising patients about the risk of osteolysis and monitoring closely patients who complain of pain with motion after surgery.

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

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.

Arthroscopy-Assisted Scapholunate Reconstruction With Internal Brace Augmentation

Various surgical techniques exist to repair or reconstruct complete scapholunate (SL) interosseous ligament tears, including capsulodesis, static or dynamic tenodesis, ligament reconstruction with tendon graft, bone-retinaculum-bone reconstruction, and the reduction and association of the scaphoid and lunate (RASL) procedure. The choice of surgical technique depends on arthroscopic assessment using the Geissler classification and European Wrist Arthroscopy Society staging of SL injury. This article describes arthroscopy-assisted extracapsular SL reconstruction using free tendon graft and internal brace augmentation for the treatment of unrepairable complete SL interosseous ligament tears.
