Knotless Webspace Reconstruction Technique for Central Metacarpal Ray Resections

Area of Science:

• Orthopedic surgery
• Hand surgery
• Reconstructive procedures

Background:

• Ray amputations of the hand are performed for various reasons including trauma, infection, and neoplasms.
• Central digit ray amputations can lead to significant hand function impairment due to the resulting gap between remaining digits.
• Existing methods for addressing this gap include ligament reconstruction and bone transposition.

Purpose of the Study:

• To describe a novel technique for deep transverse metacarpal ligament reconstruction using knotless suture anchors after central digit ray amputation.
• To evaluate the cosmetic and functional outcomes of this new technique.

Main Methods:

• A case series describing a novel knotless suture anchor reconstruction of the deep transverse metacarpal ligament.
• The technique involves a single incision for reconstruction.
• Immediate range of motion was permitted post-operatively.

Main Results:

• Two cases utilizing the knotless suture anchor technique were presented.
• Both cases demonstrated satisfactory cosmetic and functional outcomes.
• The technique proved to be technically simple.

Conclusions:

• Knotless webspace reconstruction using suture anchors is a viable and effective method for central metacarpal ray resection.
• This technique facilitates immediate post-operative motion.
• Satisfactory patient outcomes regarding both function and aesthetics were achieved.
