Abstract
Summary: Reconstructing subtotal or total volar fingertip avulsions remains a complex challenge, particularly in the absence of replantation options. Traditional flap techniques may be contraindicated or associated with significant donor-site morbidity. We describe a simple, reproducible technique using autologous adipose tissue grafting combined with platelet-rich plasma (PRP) - a method we refer to as "lipo-layering" - for the treatment of severe pulp avulsion injuries with exposed bone, tendon, and joint.Initially conceived as a temporary biological dressing while awaiting definitive reconstruction, lipo-layering unexpectedly resulted in complete granulation and re-epithelialization without the need for further surgical intervention. Over a 15-month period, six patients with seven injured digits underwent one or two sessions of lipo-layering. All grafts integrated successfully, with full coverage achieved in less than six weeks. No flap procedures or secondary grafts were required. Functional outcomes were favorable: full proximal interphalangeal (PIP) and distal interphalangeal (DIP) joint extension in all cases, near-complete DIP flexion in five out of seven digits, and minimal pain or cold intolerance. Sensory recovery ranged from 1 to 2g monofilament threshold.These results suggest that lipo-layering offers a promising alternative to more invasive techniques for volar fingertip reconstruction, particularly in cases involving deep structural exposure. The technique appears to be associated with minimal morbidity and is compatible with standard wound care protocols, making it a viable addition to the armamentarium of reconstructive hand surgery.
期刊介绍:
For more than 70 years Plastic and Reconstructive Surgery® has been the one consistently excellent reference for every specialist who uses plastic surgery techniques or works in conjunction with a plastic surgeon. Plastic and Reconstructive Surgery® , the official journal of the American Society of Plastic Surgeons, is a benefit of Society membership, and is also available on a subscription basis.
Plastic and Reconstructive Surgery® brings subscribers up-to-the-minute reports on the latest techniques and follow-up for all areas of plastic and reconstructive surgery, including breast reconstruction, experimental studies, maxillofacial reconstruction, hand and microsurgery, burn repair, cosmetic surgery, as well as news on medicolegal issues. The cosmetic section provides expanded coverage on new procedures and techniques and offers more cosmetic-specific content than any other journal. All subscribers enjoy full access to the Journal''s website, which features broadcast quality videos of reconstructive and cosmetic procedures, podcasts, comprehensive article archives dating to 1946, and additional benefits offered by the newly-redesigned website.
