Highlights Overall number of children with trauma dropped during the pandemic, and sex-related difference in frequency of trauma visits decreased. Proportion of pediatric injuries due to motor vehicle accidents didn't change. Proportion of home injuries increased concurrent with a decline in simple falls. Frequency of humeral supracondylar region, radioulnar shaft, distal forearm and proximal tibia fractures increased during COVID-19 outbreak.
Introduction: Despite the obvious advantages of arthroscopic rotator cuff repair, there are no definitive evidences regarding the superiority of this method over open surgery. The aim of this study is to compare the results of arthroscopic rotator cuff repair and open repair surgery. Methods: A total of 52 patients referring to a general university hospital were included in the study and assigned to two groups of arthroscopic repair and open repair. Demographic information of patients and the presence of any underlying disease and the grade of rotator cuff tear were recorded. The pain scores of the patients were measured three times, before, 48 h after surgery and 6-month follow-up, using the VAS system. To evaluate the clinical performance of patients, UCLA scoring system (only 6 months after the surgery) and Constant (before and 6 months after surgery) were utilized. Results: 32 patients were assigned to the open repair surgery and 20 to the arthroscopic repair group. The two groups were not significantly different in terms of pain variables, 48 hours after operation (P = 0.054) and 6 months after operation (P = 0.638), constant score 6 months after operation (P = 0.157) and UCLA shoulder rating scale 6 months after surgery (P = 0.167). Moreover, there was not any significant difference between the two groups with regard to these variables before surgery. Conclusions:The results of this study showed that arthroscopic rotator cuff repair was a safe procedure which was as effective as open repair surgery. Also, reduced postoperative pain was one of the advantages of this method noted in the present study, although the long-term severity of pain in this method was not significantly different from the pain of patients undergoing open surgery.
Leiomyosarcoma is an aggressive type of soft tissue neoplasm that originates from smooth muscle cells; it is typically found in the uterus, gastrointestinal tract, and retroperitoneum. Primary leiomyosarcoma of bone is an extremely rare phenomenon first reported in 1965. Here, we present a case of primary leiomyosarcoma of bone occurred in the proximal humerus of a 41-year-old man who was referred to our orthopaedic clinic with a chief complaint of persistent left shoulder pain. Radiological investigations revealed a proximal lesion of the left humerus with periosteal reaction. Core needle biopsy of the lesion was performed later, which pointed to primary leiomyosarcoma of bone as the underlying pathology. Subsequently, complete resection of the lesion and prosthetic replacement of the proximal humorous were performed. The patient was followed three months after the surgery, and no sign of local recurrence or metastatic lesion was detected. To the best of our knowledge, this is the first case report of primary leiomyosarcoma of bone in Iran.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
