APL Lasso Suspensionplasty for Trapeziectomy

Area of Science:

• Orthopedic Surgery
• Hand Surgery
• Rheumatology

Background:

• Base of thumb arthritis is a prevalent condition, frequently necessitating surgical intervention in advanced stages.
• Current treatments like trapeziectomy with ligament reconstruction or suspension lack a universally superior method and carry inherent risks.

Purpose of the Study:

• To introduce and describe a novel surgical technique for managing late-stage base of thumb arthritis.
• To present early clinical outcomes of this new method, focusing on its efficacy and safety profile.

Main Methods:

• A novel technique involving the use of an accessory slip of the abductor pollicis longus (APL) tendon.
• The APL slip is looped around the base of the second metacarpal to provide suspension.
• This suspension aims to prevent metacarpal subsidence following trapeziectomy.

Main Results:

• The described technique offers a potential alternative for metacarpal suspension after trapeziectomy.
• It aims to mitigate risks associated with existing suspension or reconstruction methods.
• Early clinical results indicate promising biomechanical strength and safety.

Conclusions:

• This novel APL tendon suspension technique presents a viable option for base of thumb arthritis treatment.
• It may offer comparable biomechanical stability with potentially reduced complications compared to traditional methods.
• Further research and larger studies are warranted to fully establish its long-term efficacy.
