This study describes the technique and short-term follow-up of ultrasound-guided injections for treating symptomatic Bennett lesions in baseball players. From August 2014 to August 2021, 13 injections were performed on 10 male players (mean age 25 years), including major and minor league pitchers and a high school pitcher. The procedure involved a posterior approach glenohumeral injection with a slightly medial transducer position. Anesthetic and steroid were injected onto the Bennett lesion surface, avoiding the glenohumeral joint. MRIs confirmed Bennett lesions in all patients, with ultrasound corroborating in most cases. Immediate symptom relief was reported in 67% of injections, with no complications. Fastball velocity data showed minimal post-procedure changes, with mixed results on the long-term effectiveness. The study concludes that while the procedure is safe and can provide temporary relief, its clinical utility varies.
