Abstract

Background: Open repair of the Achilles tendon carries a risk of wound complications and infection. The Achilles tendon is covered by a thin layer of skin and subcutaneous tissue, which has a fragile blood supply. The full plantarflexion position may cause sustained blanching of the skin above the Achilles tendon. However, no reports have described the in vivo blood flow (BF) changes at the skin surface with ankle position. This study aimed to use laser Doppler flowmetry to evaluate the in vivo BF at the skin surface and thereby clarify the changes in BF with ankle position.

Methods: The study cohort comprised 30 feet in 15 participants with no history of Achilles tendon rupture. Laser Doppler flowmetry was used to measure the BF at the skin surface above the medial Achilles tendon in the natural plantarflexion (NP) and full plantarflexion (FP) positions.

Results: In the NP and FP positions, the BF at 5 cm proximal to the calcaneal insertion (frequent site of Achilles tendon rupture) was 1.50 ± 0.32 and 0.97 ± 0.28 mL/min/100 g, respectively (P < .0001).

Conclusion: The BF at the skin surface adjacent to the medial Achilles tendon at 5 cm proximal to the calcaneal insertion was significantly less in the FP position than the NP position.

被动踝关节跖屈位置和跟腱附近的皮肤表面血流。

背景：开放式跟腱修复术有伤口并发症和感染的风险。跟腱被一层薄薄的皮肤和皮下组织覆盖，血液供应脆弱。完全跖屈位置可能导致跟腱上方的皮肤持续变白。然而，没有报告描述了脚踝位置时皮肤表面的体内血流（BF）变化。本研究旨在使用激光多普勒流量计来评估皮肤表面的体内BF，从而阐明BF随踝关节位置的变化。方法：研究队列包括15名没有跟腱断裂史的30英尺参与者。激光多普勒流量计用于测量在自然跖屈（NP）和完全跖屈（FP）位置的内侧跟腱上方的皮肤表面处的BF。结果：在NP和FP位置，BF在5 跟骨插入点（跟腱断裂的常见部位）近端cm为1.50 ± 0.32和0.97 ± 0.28 毫升/分钟/100 g、分别为（P 结论：5岁时内侧跟腱附近皮肤表面BF 在FP位置中距跟骨插入物近端cm的距离明显小于NP位置。

期刊介绍： Foot & Ankle International (FAI), in publication since 1980, is the official journal of the American Orthopaedic Foot & Ankle Society (AOFAS). This monthly medical journal emphasizes surgical and medical management as it relates to the foot and ankle with a specific focus on reconstructive, trauma, and sports-related conditions utilizing the latest technological advances. FAI offers original, clinically oriented, peer-reviewed research articles presenting new approaches to foot and ankle pathology and treatment, current case reviews, and technique tips addressing the management of complex problems. This journal is an ideal resource for highly-trained orthopaedic foot and ankle specialists and allied health care providers. The journal’s Founding Editor, Melvin H. Jahss, MD (deceased), served from 1980-1988. He was followed by Kenneth A. Johnson, MD (deceased) from 1988-1993; Lowell D. Lutter, MD (deceased) from 1993-2004; and E. Greer Richardson, MD from 2005-2007. David B. Thordarson, MD, assumed the role of Editor-in-Chief in 2008. The journal focuses on the following areas of interest: • Surgery • Wound care • Bone healing • Pain management • In-office orthotic systems • Diabetes • Sports medicine
