This technical note presents a novel ligament-sparing surgical technique for treating SLIL tears ranging from grade 2 to 4 of the Garcia-Elias classification. Materials and Methods: A retrospective study was performed on ten patients treated with this novel technique. The technique involves a dorsal approach to the wrist through a 5–7 cm incision ulnar to Lister’s tubercle. After exposing the scapholunate joint, reduction is performed using Kirschner wires (K-wires) as joysticks, followed by stabilisation with three K-wires through the scapholunate, scapho-capitate, and radio-lunate joints. Two 2.3 mm suture anchors with double sutures are placed where the reduction K-wires were removed. One pair of sutures connects the anchors and any remaining SLIL tissue, while the second pair create a shoelace-like capsulodesis. Post-operative care includes staged K-wire removal at one and two months, with progressive rehabilitation before returning to weight-bearing activities at six months. Results: All patients improved in pain and function. The technique addresses SLIL injuries by restoring both coronal alignment through ligament repair and sagittal alignment via dorsal capsulodesis. The use of suture anchors and direct repair preserves the native tissue while reinforcing the dorsal capsule–scapholunate septum complex, avoiding the need for tendon grafts or extensive bone tunnelling. Conclusions: This ligament-sparing technique offers several advantages, including absence of donor site morbidity, minimal damage to carpal cartilage and vascularity, and preservation of surgical options should revision be necessary. The procedure effectively addresses both components of scapholunate instability while maintaining a relatively straightforward surgical approach.
