Asynchronous Bilateral Achilles Tendon Rupture with Selective Androgen Receptor Modulators: A Case Report.

JBJS Case Connect 2021 04 9;11(2). Epub 2021 Apr 9.

Department of Orthopaedic Surgery, MedStar Union Memorial Hospital, Baltimore, Maryland.

Case: A 36-year-old male competitive powerlifter sustained asynchronous bilateral Achilles tendon ruptures after using 2 types of selective androgen receptor modulators (SARMs). Both tendon ruptures occurred near the myotendinous junction and were treated with open surgical repair and an initial period of immobilization followed by progressive weightbearing and rehabilitation; no postoperative complications were observed.

Conclusion: Previous studies have reported that anabolic androgenic steroids have a deleterious impact on tendon structure and function. This case suggests that SARM compounds may also predispose users to Achilles tendon rupture.

Neer Award 2018: Benzoyl peroxide effectively decreases preoperative Cutibacterium acnes shoulder burden: a prospective randomized controlled trial.

Background: Benzoyl peroxide (BPO) solutions effectively reduce Cutibacterium acnes (formerly Propionibacterium acnes) on the face, neck, and back in nonoperative settings. This study compared preoperative application of BPO vs. chlorhexidine gluconate (CHG) in decreasing shoulder C acnes skin burden in surgical patients.

Methods: Eighty patients undergoing shoulder surgery were prospectively enrolled in a randomized double-blind trial at 1 institution from August 2015 to April 2017. Participants were randomized to 5% BPO or 4% CHG for 3 consecutive days. The nonoperative shoulder had no intervention and served as the negative control. Skin cultures of both shoulders were obtained via a detergent scrub technique the day of surgery at anterior, lateral, and posterior sites and the axilla.

Results: Fewer positive cultures were obtained from the BPO-treated side compared with the contralateral side (P = .0003), and no change was shown for the CHG group (P = .80). Shoulders treated with BPO showed a statistically significant reduction in C acnes counts compared with CHG at anterior (P = .03) and posterior (P = .005) portal sites. No significant difference was found at the axilla (P = .99) or lateral portal site (P = .08). No postoperative infections or wound complications occurred in either group.

Conclusions: BPO is more effective than CHG at reducing C acnes on the shoulder. Decreasing the skin burden of C acnes may reduce intraoperative wound contamination and postoperative infection. BPO should be considered as an adjunctive preoperative skin preparation considering its potential benefit, low risk, and low cost.
