Trends and complications of distal biceps tendon repair among American Board of Orthopaedic Surgery part II oral examination candidates.

Abstract

Surgical fixation of distal biceps tendon ruptures can restore supination strength and minimize biceps fatigue, resulting in high patient satisfaction rates. Surgical approaches can vary (single incision vs. double incision), and the number of fixation techniques has increased in recent years. The reported rate of postoperative complications after surgical repair of distal biceps tendon injuries is high, ranging from 15% to 35%. The purpose of this study was to assess the trends and postoperative complication profile among newly trained surgeons who performed distal biceps tendon repairs utilizing the American Board of Orthopaedic Surgery database. The American Board of Orthopaedic Surgery database was retrospectively queried for patients treated with distal biceps tendon repair by part II examination candidates between 2017 and 2020. Distal biceps tendon repairs were isolated using the Current Procedural Terminology code 24,342. Distal triceps tendon injuries were excluded with International Classification of Diseases code S46.3∗∗. Patient demographics, intraoperative data, and surgeon fellowship training were collected. Surgeon-reported postoperative 90-day complications, including general anesthetic, medical, and surgical complications, rates of readmission, and rates of reoperation were recorded. Comparisons of rates among patient groups organized by surgeon fellowship training were performed using the chi-squared test. A total of 2089 distal biceps tendon repairs were included in the analysis. The average patient age was 47.5yr, and 97.3% of patients were men. The majority of cases was performed by surgeons with fellowship training in sports medicine, hand/upper extremity, and shoulder and elbow, with 867 (41.5%) cases performed by sports medicine-trained surgeons, 740 (35.4%) by hand/upper extremity-trained surgeons, and 313 (15.0%) by shoulder and elbow-trained surgeons. In total, 608 (29.1%) patients experienced an anesthetic (0.2%), medical (1.1%), or surgical (28.2%) complication. The most common surgical complications were nerve injury (20.6%), failure of tendon repair or fixation (2.4%), and infection (1.7%). The overall reoperation rate was 2.4%. There were no significant differences in complication or reoperation rates among subspecialty training received. Among newly trained surgeons, those with fellowship training in sports medicine, hand/upper extremity, and shoulder and elbow performed the most distal biceps tendon repairs, and there was no difference in complication rates among subspecialty training received. Complication rates after distal biceps tendon repair performed by newly trained surgeons were similar to those previously reported in large cohort studies, with nerve injury as the most common complication.
