RESUMO
Heterotopic ossification (HO) refers to the process of forming bony tissues in extra-skeletal sites such as muscles and soft tissues. This pathological process most commonly commences following trauma, surgery, and fractures. Rarely, HO can compress nearby neurovascular structures. To the best of our knowledge, however, no previous reports exist of HO serving as second-hit to partially injured ulnar nerve in the pediatric population. We present a case of a 6-year-old girl with complete high ulnar nerve palsy caused by medial epicondylar fracture followed by development of HO around the elbow. The patient was initially managed conservatively. Four months after the first visit, she presented with complete ulnar nerve palsy that was not evident on the initial presentation. Based on further investigations, she was taken to OR for release of the cubital tunnel and anterior transposition of ulnar nerve. On further follow-up, the patient regained sensory and motor functions of the ulnar nerve with minimum sequalae. Post-traumatic ulnar nerve injury is well described in the literature as resulting from initial trauma or as an iatrogenic injury following fracture reduction and fixation. HO in the pediatric age group is considerably rare, occurring after trauma and burn injuries. Surgical timing of HO release remains controversial. No previous reports of HO complicating traumatic ulnar nerve palsy in pediatric patients exist. In the current case report, partial ulnar nerve injury was initially due to medial epicondylar fracture, but it had progressed to full blown ulnar palsy secondary to superimposed HO. Early HO takedown combined with decompression of ulnar nerve are crucial to ensure complete nerve recovery.
RESUMO
Background: Knowledge regarding surgical site infections (SSIs) can help reduce hospital stay, morbidity, and mortality associated with SSI. Objectives: This study aimed to determine the knowledge and awareness of SSI among patients undergoing surgeries across Saudi Arabia. Methods: This multi-center cross-sectional study included adult patients (aged >18 years) who underwent surgery at six centers located across the five regions of Saudi Arabia. A 36-item questionnaire was used to elicit data regarding demographics, patient's health status, procedures, and hospitalization history and awareness and knowledge about SSIs. Results: A total of 375 patients were included (equally for all five regions of Saudi Arabia). Most patients were male (55.7%) and aged 18-34 years (44%). Most respondents (49.1%) had poor awareness; being illiterate and from the Northern region were significant factors (P = 0.001). Patients with no history of surgery (P = 0.001) or SSI (P = 0.003) also had poor awareness levels. In terms of knowledge, 45.8% and 35.2% of the participants had fair and poor knowledge, respectively, with the level of knowledge being significantly associated with region (P = 0.001). Patients those aged >65 years had poor knowledge (P = 0.033), while of males had good knowledge (P = 0.02). Patients with no history of surgery had poor knowledge of SSIs (P = 0.003). Only 32.8% of the patients recalled having been educated by healthcare workers. About 42% learned of SSIs from sources outside the hospital, with internet/social media platforms accounting for 48.4% of such sources. Conclusion: A significant proportion of the patients included in this study had poor awareness and knowledge of SSIs. The study highlights the need for strengthening the preoperative patient education in Saudi Arabia to reduce the likeliness of SSIs.
