RESUMEN
ABSTRACT: Golf is a popular sport played by individuals of varying age and skillsets. The golf swing is unique and complex, creating potential for various musculoskeletal injuries in both amateur and professional golfers. Understanding the basic biomechanics of the golf swing and its relation to injury etiology can assist the health care provider in recognizing and preventing musculoskeletal injuries secondary to golf. Most injuries occur in the upper limb and the lumbar spine. This review describes musculoskeletal pathologies seen in golfers with respect to anatomic area and golf swing biomechanics, while summarizing effective prevention strategies and swing modifications to address these potential injuries.

Objective: To assess the effects of platelet-rich plasma (PRP) injection among patients with thumb carpometacarpal (CMC) joint osteoarthritis (OA). Design: Retrospective chart review with follow-up questionnaires/surveys. Post-procedure, patients were sent standardized, automatically-generated follow-up questionnaires, and contacted for a survey regarding patient-reported outcomes. Setting: Single institution (tertiary care hospital) outpatient clinic from 2015 to 2020. Participants: Nineteen adult patients (9 women; average age 65.0 [±6.3 years]) who received a PRP injection for OA of 1 or both thumb CMCs (N=19). Interventions: Platelet-rich plasma injection. Main Outcome Measures: Outcome measures included symptom improvement (subjective, visual analog scale), duration of benefit, subsequent procedures, satisfaction, and side effects/adverse events. Cellular composition of whole blood and PRP injectate (platelets, erythrocytes, leukocytes, neutrophils, lymphocytes, and monocytes) were analyzed. Results: Subjects reported moderate or excellent symptom improvement in 68.8% of injected joints and were moderately or very satisfied with 68.8% of the procedures. Mean patient-reported duration of benefit was 15.6 months (±19.5) months (mean duration of follow-up: 32.4 [±18.1] months). There were no major complications attributed to the procedures, but 1 patient was diagnosed with presumed unrelated lymphoma 2 weeks post-procedure. PRP mean platelet concentration was 1787.77 (±687.14) × 109/L, resulting in a mean platelet concentration factor of 8.80 (±4.19) times baseline and mean platelet dose of 1881 × 106. Other PRP cell concentration factors were erythrocytes, 0.02; neutrophils, 0.14; lymphocytes, 3.76; and monocytes, 3.29. Conclusions: PRP injection appears to be a safe and potentially effective treatment option for pain related to first CMC OA. Further study is needed to optimize treatment protocols and better understand which patients are most likely to benefit.
RESUMEN
Objective: To compare validity indices of the King-Devick (KD) test and Sport Concussion Assessment Tool 5 (SCAT5) for traumatic events in MMA, and to determine if perfusion events (alterations in consciousness as the result of choke holds) cause similar changes in KD/SCAT5 scores. Design: A prospective cohort study in MMA fighters who completed KD and SCAT5 assessments before and after a match. Outcomes were categorized as non-event, traumatic event, or perfusion event. KD/SCAT5 changes were compared between all athletes. Participants: One hundred forty MMA athletes (7 women, 133 men), mean age=27.1 ± 4.9 years. Intervention: N/A. Main outcome measures: King-Devick (KD) test and Sport Concussion Assessment Tool 5 (SCAT5). Results: Among the 140 athletes, 19 sustained traumatic and 15 perfusion events. Testing provided sensitivities/specificities of 21.05%/93.39% (KD) and 77.78%/52.99% (SCAT5) in detecting a traumatic event. KD and SCAT5 Symptom Severity scores differed between athletes with and without traumatic events (P=.041 and .014). KD and SCAT5 Symptoms Score changes were observed between athletes with and without traumatic events (P=.023 and .042). Neither KD nor SCAT5 differed significantly between athletes with and without perfusion events. Conclusions: The KD test provides high specificity and the SCAT5 demonstrates reasonable sensitivity when detecting a traumatic event. Of the SCAT5, symptoms-related scores may most effectively identify a traumatic event. A traumatic event may cause KD/SCAT5 changes similar to a concussion, while perfusion events did not.
