Cable-Augmented, Quad Ligament Tenodesis Scapholunate Reconstruction.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Wrist Biomechanics

Background:

• Maintaining scapholunate reduction post-reconstruction is challenging.
• Scapholunate ligament injuries often lead to wrist instability and pain.
• Previous reconstruction methods have variable success rates.

Purpose of the Study:

• To evaluate the efficacy of scapholunate reconstruction using tensionable suture anchors.
• To assess the ability of this technique to reduce and maintain scapholunate interval.
• To analyze functional outcomes and pain reduction following the procedure.

Main Methods:

• Scapholunate reconstruction performed in 8 patients utilizing tensionable suture anchors.
• Flexor carpi radialis tendon graft used for ligamentous stabilization.
• Ulnar advancement capsulodesis employed for dorsal reinforcement.

Main Results:

• Significant improvement in mean pain score (5.8 to 2.1).
• Restoration of wrist range of motion: extension 56°, flexion 44°.
• Improved grip strength (95% of contralateral side) and reduced scapholunate interval (3.0 mm).

Conclusions:

• Tensionable suture anchors provide a stable construct for scapholunate reconstruction.
• The technique effectively reduces and maintains scapholunate diastasis.
• Further long-term follow-up is necessary to confirm sustained benefits.
