Published: July 2021

Background: Little League shoulder (LLS) is an overuse injury characterized by throwing-related pain that commonly presents in adolescent male athletes. Investigations into the optimal duration of rest from throwing and protocols for graduated return to sports (RTS) are lacking.

Purpose: To summarize the current literature with respect to the diagnosis, management, RTS, and return to throwing for LLS.

Design: Systematic review; Level of evidence, 4.

Methods: The databases EMBASE, MEDLINE, and PubMed were searched between inception and April 22, 2020. References of retrieved records were reviewed for potentially eligible studies. English-language studies that reported the diagnosis and/or management of LLS in children or adolescents were included. Studies of animals or cadavers, review articles, and non-peer reviewed records were excluded. Data were summarized narratively using descriptive statistics.

Results: Overall, 23 studies (21 level 4 studies, 2 level 3 studies) met the criteria for a total of 266 participants with a weighted mean age of 12.8 years (range, 7.4-17 years). Treatment recommendations evolved from prolonged rest and complete cessation of throwing to shorter periods of rest and graduated RTS. Less than half (11/23) of studies reported specific criteria to RTS; 1 case report discussed a coaching strategy to resume throwing, and 1 case report discussed a regimented throwing program. The proportion of participants returning to any sport participation was 94.0% (n = 157/167). The proportion returning to their preinjury level of sport was 92.5% (n = 123/133). Upon RTS, 18.7% (n = 35/187) of participants experienced a recurrence of symptoms. Premature closure of the epiphysis was reported in 1 participant.

Conclusion: Young athletes with LLS may return to play after a period of rest, and a high proportion return to their preinjury level of sport. Further prospective studies are warranted to develop evidence-based, graduated RTS protocols and to better capture any long-term sequelae of the condition.

Background: The authors report the first case of thoracic interdural spinal cysts presenting as radiculopathy attributed to overdrainage-related cervical venous plexus enlargement. This case emphasizes the importance of considering interdural spinal cysts and cerebrospinal fluid overdrainage in the differential diagnosis of radiculopathy.

Observations: A 37-year-old male patient with a history of orthostatic headache presented with bilateral deltoid muscle atrophy consistent with C5 radiculopathy.

Purpose: Cardiac computed tomography angiography (CCTA) has significantly advanced the visualization of cardiac structures, particularly valves. We assessed the diagnostic performance of CCTA in diagnosing the most common disorders affecting the aortic valves requiring surgery-papillary fibroelastoma, infective endocarditis, and degeneration.

Methods: This retrospective study included patients who underwent aortic valve resection between 2016 and 2023 and had a preceding CCTA.

Cervicofacial non-tuberculous mycobacterial infection should be a part of the differential diagnosis for immunocompetent children ages 1 to 5 years who present with painless submandibular or preauricular lymphadenopathy. Although a benign and self-limiting disease, patients can develop a chronically draining fistula if not diagnosed and treated promptly. The diagnostic process can be managed with a combination of microbiological studies, cytology, laboratory tests, and imaging studies.

The traditional method of performing open common bile duct exploration (OCBDE) was replaced by a less invasive procedure known as laparoscopic common bile duct exploration (LCBDE) in elective surgery. But at present, the application of this technique is considered novel and controversial to treat acute cholangitis (AC). The aim of our systematic review was to investigate the safety and efficacy of laparoscopic surgery in patients with AC.
