Long-Term Follow-Up of Synthetic Ligament (Orthotape) Usage in Reconstructive Surgery of the Hand

Abstract

PurposeSynthetic ligaments have been widely used in the knees for anterior cruciate ligament reconstruction and in the shoulder rotator cuff repair, but they have been rarely used in the hand. The only reported usage is in the Artelon space for carpometacarpal joint osteoarthritis. We describe our experience using the synthetic ligament or scaffold known as Orthotape (its predecessor was known as the Leeds-Keio ligament) in the hand and fingers.MethodsWe retrospectively reviewed all patients in whom polyester synthetic ligament (Orthotape) was used to reconstruct absent tendons involving both flexor and extensor compartments between 2011 and 2016. The reconstruction procedures were performed as elective surgeries. The tendons were absent due to either trauma or infection. We collected data on demographics, the injury mechanism, prior surgeries, the zone of tendon loss, the presence of skin flaps, and the number of strips of ligament inserted.ResultsWe inserted 18 strips of Orthotape in the hands of 9 patients. The follow-up period was 3–7 years, and the mean duration of Orthotape in the hand was 44.1 (range, 1–91) months. Four strips extruded, resulting in a 22.2% extrusion rate. Of the 9 patients, 5 retained the Orthotape within their hand for time periods ranging from 60 months (5 years) to 91 months (7.5 years). The extruded strips were in the superficial areas of the hand. Seven patients had traumatic injuries with varying severity and 2 had infections.ConclusionsThe high extrusion rate of Orthotape discourages its use in the superficial areas of the hand, including flexor and extensor surfaces of the fingers and hand. We recommend its usage in regions with a thick skin cover such as underneath a flap or in deep areas such as the palm. Nevertheless, it remains as a possible option in cases of complex reconstruction with a limited availability of donor tendons.Type of study/level of evidenceTherapeutic IV.
