[Electric scooter-associated orthopedic injuries cause long absence from work, regret and are emerging as a major cause of hip fractures in young individuals: a comprehensive study from a regional trauma center in a densely populated urban setting]. / Orthopädische Verletzungen im Zusammenhang mit Elektroscootern führen zu langer Abwesenheit vom Arbeitsplatz, Bedauern und werden zu einer Hauptursache für Hüftfrakturen bei jungen Menschen: eine umfassende Studie in einem regionalen Traumazentrum in einem dicht besiedelten städtischen Gebiet.

PURPOSE: This study aimed to give a full spectrum of orthopedic injuries associated with electric scooter (e-scooter) use and analyze related factors, report on follow-up data from the patient's perspective and make a comparative etiological analysis of young adult hip fractures. METHODS: A total of 851 consecutive patients were admitted to the Emergency Department following e­scooter injuries between January 2021 and July 2022, of whom 188 had 214 orthopedic injuries. The demographics, injury, and incident characteristics of these patients were collected. All fractures were classified as per the AO/OTA classification. Two groups were created as operatively or conservatively treated patients and data were comparatively analyzed. Follow-up examination incorporated a survey using binary questions on patients' perspectives. An etiological comparative analysis of hip fractures in young adults admitted to the same center between 2016 and 2022 was conducted. RESULTS: The median patient age was 25. Inexperienced drivers constituted 32% of the injured. The protective gear use rate was at 3%. Higher speed (p = 0.014) and age (p = 0.011) were significantly associated with operative treatment. A total of 39% of the operated patients could not return to preinjury physical function, while 74% regretted using an e­scooter. The most common etiological factor for traumatic young hip fractures was fall from a height between 2016 and 2020, whereas it became e­scooter accidents in 2021-2022. CONCLUSION: The rate of e­scooter-related operative treatment is high and leaves the patient in regret (84%) and a physically limited condition (39%). A speed limit of ≤ 15 km/h could decrease the rate of operative injuries. The e­scooter was identified as the top etiological factor in the last 2 years for traumatic young hip fractures. LEVEL OF EVIDENCE: II, Diagnostic cohort study.

A More Conservative Approach in the Surgical Management of Pediatric Physeal Ankle Fractures Should be Preferred: Mid to Long-term Functional Outcomes of Three Different Surgical Techniques for Salter-Harris Type II and Triplane Distal Tibial Fractures.

BACKGROUND: Pediatric physeal ankle fractures carry a high risk of complications. This study aimed to (1) investigate the effect of anatomic reduction of the physis on mid to long-term functional outcomes in Salter-Harris type II and triplane distal tibial physeal fractures (DTPFs) and (2) compare the outcomes of 3 different surgical techniques applied in these fractures. METHODS: The database of a single level-I trauma center was retrospectively reviewed for DTPFs between 2012 and 2022. A total of 39 eligible patients with operative Salter-Harris type II and triplane fractures between 2012 and 2022 were included. Surgical treatment methods were closed reduction-percutaneous fixation (CR-PF), open reduction-screw fixation, or open reduction-plate fixation. Patients were further divided into subgroups for fractures reduced anatomically (<1 mm) or nonanatomically (1 to 3 mm). The primary outcome measures were the American Orthopaedic Foot and Ankle Society Score, ankle range of motion, presence of premature physeal closure and angular deformities, and Takakura ankle osteoarthritis grade. RESULTS: A total of 39 patients were included, with an average age of 12.9 ± 2.2 years. The mean follow-up time was 68.9±38.0 months. The CR-PF group had higher postoperative fracture displacement ( P = 0.011). American Orthopaedic Foot and Ankle Society scores were excellent in all groups, statistically similar between surgical techniques, and similar between anatomic and nonanatomic reduction groups. The CR-PF group ( P =0.030) and nonanatomic reduction ( P = 0.030) provided a significantly lower ankle osteoarthritis rate. All 4 patients with premature physeal closure were observed in patients treated with open techniques. CONCLUSIONS: CR-PF for the treatment of DTPFs should be preferred in suitable cases as it is less invasive and provides satisfactory mid to long-term functional outcomes without increasing complications compared with anatomic reduction and open techniques. LEVEL OF EVIDENCE: Level III.
