What’s New in Shoulder and Elbow Surgery 2019

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of all such OrthoBuzz summaries. This month, Matthew R. Schmitz, MD, JBJS Deputy Editor for Social Media, selected the most clinically compelling findings from the 50 studies summarized in the October 16, 2019 “What’s New in Shoulder and Elbow Surgery.

Rotator Cuff Repair
–A randomized controlled trial compared immediate and delayed surgical repair of partial-thickness rotator cuff tears.1 No differences in retear rates were found, suggesting that a trial of nonoperative management remains appropriate for partial-thickness tears.

–The search continues for biologic augmentations to improve healing after rotator cuff repair. A study that randomized patients to weekly human growth hormone injections for 3 months or no injections after repair of a large tear found no difference in healing rates.2 Another randomized study of the effect on cuff-repair healing of platelet-rich plasma in a fibrin matrix found no improvement.3 A similar randomized trial of platelet-rich plasma plus thrombin in patients with a single-row repair of the supraspinatus found no differences in clinical outcomes or healing rates.4

–Psychosocial factors have been associated with pain relief and functional improvement after rotator cuff repairs. A longitudinal cohort study found that higher fear-avoidance behavior and alcohol use of ≥1 to 2 times per week compared with alcohol use ≤2 to 3 times per month negatively impacted shoulder pain and function at 18 months postoperatively.5

Osteochondritis Dissecans of the Capitellum
–A study evaluated predictors of success of nonoperatively treating patients with osteochondritis dissecans of the capitellum who did not have fluid underneath the fragment.6 Researchers found that lesion healing was associated with the following:

  • Smaller overall lesion size
  • No clear margins of the fragment on MRI
  • Absence of cyst-like lesions

The authors include a nomogram that clinicians can use to predict healing.

UCL Insufficiency
–A study investigated baseball position-specific factors affecting return to play after ulnar collateral ligament (UCL) reconstruction.7 Investigators found the following:

  • Position players returned to play sooner than pitchers, but they had lower rates of return to play.
  • Catchers had the lowest likelihood of return to play (58.6%) and pitchers had the highest (83.7%).

These findings could help clinicians set expectations for players undergoing UCL reconstruction.

    Great job on the article! Keep adding value! I am an Orthopedic Surgeon based in Cape Town, I might want to link this article onto my own website.
