The Rurality of Upper Extremity Firearm Injuries.

BACKGROUND: To highlight the unique spectrum of hand and upper extremity firearm injuries seen at a rural, Midwestern level 1 trauma center and identify modifiable factors that contribute to firearm injuries of the hand and upper extremity. METHODS: A retrospective review of upper extremity firearm injuries from a rural, Midwestern level 1 trauma center was collected from January 2002 to December 2019. Data acquired included injury description, demographics, injury mechanism/description/location, firearm used, toxicology, and information regarding hospitalization. Data was analyzed using Chi-squared analysis and Fisher's exact test for categorical data and the Wilcoxon rank sum test for continuous data. RESULTS: 55 patients with upper extremity firearm injuries were identified. Average age was 33.3 ± 13.0 years, 81.8% were males, and zero fatalities were identified. 58% (38) of these injuries were unintentional firearm injuries, followed by assaults at 34.6% (19). Law enforcement-related and self-inflicted injuries contributed minimally. Handguns were the most common type of firearm, used in 43.6% of cases. 7.3% (4) of injuries occurred while hunting, with 21.8% (12) total during November or December, the active deer hunting months. 92.7% (51) of all firearm injuries presented with fracture, among which 92.2% (47) met a Gustilo-Anderson classification score of at least 3A. Alcohol was detected in 20% (11) of the patients, while other drugs of abuse were detected in 36.4% (20). CONCLUSION: Our data suggests that upper extremity firearm injuries in a rural population are unique from urban injuries in that they are predominately unintentional, isolated, and non-fatal. We identify a distinct rural cohort that may benefit from better directed interventions to prevent firearm injuries and ultimately guide firearm education and public policy.Level of Evidence: III.

Inclusion of Olecranon Osteotomy With the Posterior Approach for Fixation of Distal Humerus Fractures (OTA/AO 13) Does Not Increase Surgical Complications.

OBJECTIVES: To determine if inclusion of an olecranon osteotomy to the posterior paratricipital approach for operative fixation of distal humerus fractures significantly affects surgical complication rates (OTA/AO 13). DESIGN: Retrospective comparative cohort study. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Three hundred four patients underwent open reduction internal fixation of a distal humerus fracture between 2007 and 2017. Of those, 134 met inclusion criteria (≥15 years, OTA/AO fracture type 13A, B, or C, and posterior surgical approach) for the study (n = 64 with olecranon osteotomy; n = 70 without olecranon osteotomy). INTERVENTION: Open reduction internal fixation of distal humerus fractures performed using a posterior paratricipital approach with or without olecranon osteotomy. MAIN OUTCOME MEASURE: Ulnar neuropathy (UN), fracture site bony nonunion, and surgical site infection (SSI). RESULTS: Thirty-one (33.3%) who underwent the paratricipital approach without olecranon osteotomy, and 15 patients (26.8%) who underwent olecranon osteotomy reported postoperative UN with no significant difference between approaches (P = 0.438). There was no significant difference in rates of SSI (P = 0.418) or fracture site nonunion (P = 0.263) when comparing the approaches. Subjects with Charlson comorbidity index ≥2 were more likely to not undergo an olecranon osteotomy (P = 0.01), whereas subjects with more complex fractures by OTA/AO classification were more likely to have an olecranon osteotomy approach (P = 0.001). CONCLUSIONS: Addition of an olecranon osteotomy with the paratricipital approach for fixation of distal humerus fractures does not result in higher rates of UN, fracture site nonunion, or SSI.
