Functional performance of the upper limb and the most common boxing-related injuries in male boxers: a retrospective, observational, comparative study with non-boxing population

Demographic trends of boxing-associated fractures over 10 years

BACKGROUND

Boxing is a sport well-known for the risk of injury. However, the epidemiology of boxing-associated fractures has not been well studied. This study aims to report the characteristics of boxing fractures that lead to presentation to the emergency room and evaluate the demographics and practices of the patients to prevent these injuries.

METHODS

This cross-sectional study analyzed boxing-associated fractures over a decade (2013-2022) using the National Electronic Injury Surveillance System (NEISS) database. Patients presenting to U.S. emergency departments with boxing-related injuries were categorized by age, gender, and injury location. Descriptive statistics, chi-square tests, and ANOVA were employed to assess temporal trends and associations between injury occurrence and demographic variables.

RESULTS

Analysis of 959 boxing-associated fractures (BAFs) showed that hand fractures were most common (53.64%), followed by phalanx (12.73%) and facial fractures (10.91%). Significant differences were observed across body parts (χ2 = 9.74, P < .001). Associated soft tissue injuries included lacerations, contusions, sprains, strains, and hematomas, with no significant differences among these categories (χ2 = 1.47, P = 0.832). Males experienced more BAFs than females overall, but females had a significant increase over time (F(1,9) = 4.308, p = 0.032). Most fractures occurred in recreational or sports settings (34.5%), followed by home (19.1%) and school (13.24%). The highest BAF incidence was in individuals aged 21-30 (32.18%), while the lowest was in those aged 41-50 (5.47%). From 2020 to 2022, BAFs decreased in recreational settings and increased at home during 2020-2022.

CONCLUSION

Hand fractures were the most common type of BAF. Males had significantly more BAFs, although the incidence of BAFs in females increased significantly since 2013. Fractures mainly occurred in recreational places, but from 2020-2022, most occurred at home. This shift coincided with the COVID-19 pandemic, suggesting increased home sparring. These findings emphasize the need for further research into protective measures and injury prevention in boxing.

Capitate Proximal Fragment Migration Compressing the Median Nerve in Scaphocapitate Fracture: A Case Report

BACKGROUND Scaphocapitate syndrome is a rare clinical entity consisting of a combined scaphoid and capitate fracture along with a 90- or 180-degrees rotation of the proximal capitate fragment. The syndrome is scarcely described in the literature, with proximal migration of the capitate fragment being reported only by Mudgal et al in 1995. Concurrent compression of the median nerve is a highly unfortunate event, suggesting a unique case presented here. CASE REPORT We present a unique case of scaphocapitate fracture-dislocation in a 25-year-old man with volar dislocation of the capitate's fragment deep to the median nerve. X-rays and CT scan were performed and the patient was treated few hours after the injury by a hand specialist, in order to prevent median neuropathy and avascular necrosis of the fragment. Open reduction and internal fixation utilizing a Herbert screw for the scaphoid fracture and 3 additional K-wires was performed. Immediately post-operatively, the acute neurological symptoms had subsided and good reduction was acquired radiologically. One year post-operatively the patient had regained good hand and wrist functionality, with no extension or flexion ROM deficits. CONCLUSIONS Immediate intervention in a specialized center with reduction and fixation utilizing a Herbert screw and K-wires showed favorable 1-year results in our case of scaphocapitate syndrome. The impending complications of median neuropathy and capitate avascular necrosis were avoided despite the high-risk injury pattern.
