NEUROPATIA RADIAL SECUNDÁRIA À PRÁTICA DE CROSSFIT

RESUMO

Case presentation:
Patient GDL, male, 29 years old, previously healthy, reports that after a rope climbing CrossFit activity on 12/01/21, presented with left humerus fracture, resulting in wrist fall (Strength 0/5) and elbow extension déficit (Strength 1/5).
Submitted to surgery for fracture correction with application of locking plate on 03/12/21, without complications. After the procedure, the patient persisted with clinical presentation.
An electroneuromyography done in 02/01/22 shows accentuated fibers impairment of radial nerve, probably located above the spiral sulcus, with present denervation and no signs of reinnervation.
Patient is currently being followed up with physical therapy with a strength grade of 1/5 for left wrist extension and 2/5 for ipsilateral elbow extension.
Discussion:
Crossfit is a program developed to promote the improvement of physical conditioning with exercise variability and high intensity¹.
It has gained a lot of popularity and several studies have emerged with the purpose of highlighting the physical benefits and answering questions about safety in its practice, mainly related to the higher prevalence of injuries.²
Feito et al evaluated groups of Crossfit practitioners for 04 years and showed injuries to the shoulders (39%), back (36%), knees (15%), elbows (12%) and wrists (11%) were the most common³.
Costa et al revealed that among injuries associated with Crossfit, mild/moderate ones represented 89.1% of the cases, while severe/very severe injuries 10.9% and injuries that required surgical treatment represented 2.6%⁴.
Humeral stress fractures have been described in activities with excessive use of the upper extremities and weight-lifting⁵, aspects present in Crossfit practices. Since there is a close anatomical relationship between the radial nerve and the humerus and the fact that it promotes motor innervation of the triceps and wrist, with wrist drop being the hallmark of a radial nerve injury⁶, the context and consequences of the patient's injury significantly reflectthe findings found in literature.
Conclusion:
Although Crossfit's rising popularity demonstrates an interest in physical exercise, its practice without guidance can result in serious harm to the body. The episode described brought consequences that affect the patient's life as a whole due to the current coexistence with a neuromotor dysfunction of indefinite duration, shining a light on the importance of discussions about the safety of the practice.
