The development of the suture anchor has played a pivotal role in the transition from open to arthroscopic techniques of the shoulder. Various suture anchors have been manufactured that help facilitate the ability to create a soft tissue to bone repair. Because of reported complications of loosening, migration, and chondral injury with metallic anchors, bioabsorbable anchors have become increasingly used among orthopaedic surgeons. In this review, the authors sought to evaluate complications associated with bioabsorbable anchors in or about the shoulder and understand these in the context of the total number of bioabsorbable anchors placed. In 2008, 10 bioabsorbable anchor-related complications were reported to the US Food and Drug Administration. The reported literature complications of bioabsorbable anchors implanted about the shoulder include glenoid osteolysis, synovitis, and chondrolysis. These potential complications should be kept in mind when forming a differential diagnosis in a patient in whom a bioabsorbable anchor has been previously used. These literature reports, which amount to but a fraction of the total bioabsorbable anchors implanted in the shoulder on a yearly basis, underscore the relative safety and successful clinical results with use of bioabsorbable suture anchors. Product development continues with newer composites such as PEEK (polyetheretherketone) and calcium ceramics (tricalcium phosphate) in an effort to hypothetically create a mechanically stable construct with and improve biocompatibility of the implant. Bioabsorbable anchors remain a safe, reproducible, and consistent implant to secure soft tissue to bone in and about the shoulder. Meticulous insertion technique must be followed in using bioabsorbable anchors and may obviate many of the reported complications found in the literature. The purpose of this review is to provide an overview of the existing literature as it relates to the rare complications seen with use of bioabsorbable suture anchors in the shoulder.
缝合锚的发展在肩关节从开放技术向关节镜技术的转变中发挥了关键作用。已经制造了各种缝合锚，以帮助实现软组织到骨的修复能力。由于金属锚钉存在松动、迁移和软骨损伤等并发症，生物可吸收锚钉在骨科医生中越来越受欢迎。在这篇综述中，作者试图评估与肩部周围的生物可吸收锚钉相关的并发症，并了解这些并发症在已放置的生物可吸收锚钉总数中的情况。2008 年，向美国食品和药物管理局报告了 10 例与生物可吸收锚钉相关的并发症。据报道，在肩部周围植入生物可吸收锚钉的文献并发症包括关节盂骨溶解、滑膜炎和软骨溶解。在以前使用过生物可吸收锚钉的患者中，出现这些潜在并发症时应考虑进行鉴别诊断。这些文献报告仅占每年肩部植入的生物可吸收锚钉总数的一小部分，但强调了使用生物可吸收缝合锚钉的相对安全性和临床成功结果。新产品的开发仍在继续，例如聚醚醚酮（PEEK）和钙陶瓷（磷酸三钙）等复合材料，旨在创造具有机械稳定性的结构，并提高植入物的生物相容性。生物可吸收锚钉仍然是一种安全、可重复和一致的植入物，可将软组织固定在肩部及其周围的骨骼上。在使用生物可吸收锚钉时，必须遵循精细的插入技术，这可能会避免文献中报道的许多并发症。本文的目的是提供与肩部使用生物可吸收缝合锚钉相关的罕见并发症的现有文献综述。
