Introduction: E-scooters have become increasingly popular in Turkey due to easy accessibility. In parallel with this, the number of e-scooter-related injuries has increased gradually. The aim of this study was to determine the types of e-scooter-related orthopedic injuries, to evaluate hospitalization and surgical treatments, and to investigate the loss of work of patients and the burden incurred by the healthcare system. Materials and methods: This retrospective multicentre study included all orthopaedic referrals, who were admitted to two major trauma departments in Diyarbakır from January 2022 to July 2022. Patient data were analyzed, including demographic characteristics, injury pattern, types of injury and subsequent treatment. Results: In a total of 62 patients, 105 orthopaedic injuries were identified, comprising 72.5% males and 27.5% females, with a median age of 34.21 years. Fifty-six (90.3%) patients were riders, and six were pedestrians. All associated e-scooters were rented. There were 44 fractures (41.9% of the total recorded injuries) including 8 (12.9%) open fractures. Surgery was required by 32 patients (51.6%) and 35 (56.4%) required hospital admission leading to hospitalization of 3.7 days on average. The average job loss of working patients after injury was determined as 2.4 months. Helmet use was detected in 6.4% of the e-scooter users, but no other protective equipment was detected in any of the patients. Furthermore, 19,3% of the patients had a blood alcohol level of > 10 mg/dl. Conclusions: The injuries that may result from an e-scooter accident can have long-term hospitalization and long-term job loss in the community. This imposes a significant financial burden on the national healthcare system and adversely affects public health. There is a need for precautions to be implemented such as infrastructure organisation, increased awareness of motor vehicle riders and e-scooter riders, and increased enforcement of rule compliance including not using e scooters after alcohol consumption and the use of protective equipment.

The diagnosis of posterior shoulder dislocation (PSD) is often overlooked as these injuries are not common, since clinical signs may be subtle and easily overlooked unless specifically evaluated. This study aimed to determine the factors related to clinical outcomes in patients with chronic locked PSD treated with the modified McLaughlin procedure. The study included 22 patients from 5 different clinics who were diagnosed with chronic (> 6 weeks) locked PSD and underwent the modified McLaughlin procedure. The pre- and postoperative values of shoulder forward flexion, abduction, and external rotation were recorded for each patient. At the final follow-up examination, the patient-reported clinical outcomes were evaluated through Constant-Murley Score (CMS), the Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and the University of California-Los Angeles (UCLA) shoulder scale. Defect depth and defect angle were measured on axial computed tomography sections. Evaluation was made of 14 males and 8 females aged 25–58 years. The mean time interval between the dislocation and surgery was 18.4 ± 7.4 weeks. The postoperative scale scores were DASH mean 17.1 ± 5.6, CMS median 70.0 [35.0–83.0] and UCLA shoulder scale mean 25.5 ± 6.6. Strong to excellent correlations were determined between the functional scores and the duration of dislocation. Regardless of age, gender, depth and degree of the defect, and immobilization duration, the duration of dislocation (weeks) was associated with the DASH score (beta:0.513, 95% CI:0.931–7.528, p = 0.015), CMS (beta: -0.916, 95% CI: -1.959 to -1.293, p < 0.001), and the UCLA shoulder scale (beta: -0.899, 95% CI: 0.983 to -0.618, p < 0.001). In patients with locked PSD, the primary factor influencing clinical outcomes is the duration of the dislocation, rather than humeral head defect size or patient age. PSD should be suspected in patients with shoulder trauma who present with limitations in forward flexion and abduction.

Background: This study aims to analyze long-term outcomes in patients with aneurysmal bone cysts (ABCs) and demonstrate effective disease control. In the literature, the absence of a long-term study systematically evaluating the outcomes of a population with such a significant number of patients from different age groups will shed light on our surgical preferences. Methods: The study encompassed ABC diagnoses, primarily concerning long bones (46 women, 62 men; mean age 19.4 years; range 2—67) extracted from patient records spanning from 2007 to 2022 in our clinic. The average follow-up was 81 months. Extended intralesional curettage was performed using a mechanical burr, cauterization, grafting and internal fixation in 96 patients (88.9%), whereas resection was carried out in 12 patients (11.1%). Results: Pathological fractures occurred in 35% of cases. Reconstruction was performed in five patients (4.6%; endoprosthetic in 4, biological reconstruction in 1) and seven patients (6.5%) required no reconstruction. The mean Musculoskeletal Tumor Society (MSTS) score was 95.5 (range 60–100). Complications and recurrence rates were 12% and 9.3%, respectively. Surgical choice and adjuvant agent significantly influenced long-term complications and recurrence ( p = 0.001). Conclusions: In the treatment management of aneurysmal bone cysts, extended intralesional curettage surgery coupled with the use of electrocautery and a high-speed burr has shown successful outcomes in long-term follow-up. A wider sample size with prospective randomized studies can be conducted regarding the treatment of ABCs.
