Double tightrope for basilar thumb arthritis.

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Arthritis Treatment

Background:

• Basilar thumb joint arthritis is a common condition affecting hand function.
• Surgical options aim to restore stability and alleviate pain.
• Suture button suspension offers advantages but carries risks like over-tightening and impingement.

Purpose of the Study:

• To present a modified surgical technique for basilar thumb joint arthritis.
• To address the concern of metacarpal impingement associated with suture button devices.
• To enhance thumb joint stability and facilitate early patient recovery.

Main Methods:

• Open trapeziectomy combined with the simultaneous application of two Mini TightRope button devices.
• Utilizing the suture button devices to stabilize the thumb metacarpal and prevent subsidence.
• Imbrication of the flexor carpi radialis and abductor pollicis longus tendons for construct reinforcement.

Main Results:

• The described technique provides robust stabilization of the thumb metacarpal.
• Simultaneous use of two devices prevents impingement between the thumb and index metacarpal bases.
• The surgical construct allows for earlier motion and return to work compared to traditional methods.

Conclusions:

• This surgical approach offers a stable and effective solution for basilar thumb joint arthritis.
• The technique mitigates the risk of impingement, a known complication of suture button suspension.
• It promotes improved functional recovery and long-term joint stability.
