Recurrence and return to play after shoulder instability events in young and adolescent athletes: a systematic review and meta-analysis.

BACKGROUND: Shoulder instability in athletics is a common occurrence. However, there is controversy as to whether non-operative versus operative management is the most effective treatment in youth athletes. We systematically reviewed recurrence and return to play (RTP) after shoulder instability events in youth athletes based on surgical versus non-surgical intervention. DESIGN: The systematic review concerned studies published before August 2016. Statistical analysis was performed to compare rates of recurrence for each extracted risk factor. Pooled ORs were analysed using random-effects meta-analysis. RESULTS: 17 studies comprising 654 total shoulder instability events met the criteria for inclusion (438 men and 158 women; 507 cases traumatic and 20 atraumatic). Patients were grouped by whether they received non-operative or operative treatment. The primary non-operative group was more likely to have recurrence compared to the primary operative group (OR=13.41; 99% CI 3.60 to 49.93, p<0.001). Patients <14 years old in the primary non-operative group were less likely to recur compared to those aged ≥14 years (OR=0.16; 99% CI 0.06 to 0.43, p<0.001). The rate of recurrence in patients aged <14 years was high (44.44%). For RTP, there is evidence that RTP rates were higher for primary operative patients (95.3%) versus primary non-operative (41.3%, Z=6.12, p<0.001) and secondary operative patients (77.6%, Z=2.66, p=0.008). CONCLUSIONS: This meta-analysis summarises a mix of 17 acceptable quality level II and III prospective and retrospective cohort studies. Given the superior rates of recurrence and RTP, primary operative treatment for shoulder instability should be considered in youth athletes aged ≥14 years. Additionally, the recurrence rate in athletes aged <14 years is significant.

Central cord syndrome from blast injury after gunshot wound to the spine: a case report and a review of the literature.

INTRODUCTION: Central Cord Syndrome (CCS) is the most common of the spinal cord injury syndromes. Few cases have been presented with gunshot wound (GSW) as a cause of a central cord syndrome, and none, to our knowledge, has been presented without any evidence of central canal bullet/bone fragments. CASE PRESENTATION: A 27-year-old male suffered two close-range gunshot wounds, one to the left neck and one to the left shoulder. CT scan showed C5 spinous process fracture and paraspinal muscle hemorrhage without evidence of central canal stenosis or bullet/bone fragments. Physical examination showed severe weakness and dysesthesias in bilateral upper extremities and mild weakness in bilateral lower extremities. Diagnosis of central cord syndrome was made. He was treated conservatively and started inpatient rehabilitation. Four months post injury, the patient had almost full recovery with only left proximal arm and bilateral distal hand weakness. DISCUSSION: Only four cases of CCS caused by GSW have been reported in the literature. Some suggested algorithms exist regarding the management of these patients, but still cases should be individualized depending on the specific nature of their presentation. The prognosis for patients with CCS tends to be favorable in regaining sensory, bladder, bowel, gross motor function and ambulation, but fine motor skills may remain impaired.

Benefits of Exercise in the Older Population.

Older adults 65 years of age and older compose a great portion of the US population. Physiologic changes of aging that limit function and general quality of life occur at a faster rate as we get older. There is high-quality evidence that exercise activity has many favorable benefits for older adults. The ideal exercise program in older adults should include aerobic, resistance, flexibility, and balance training. The exercise recommendations should be individually tailored to the abilities, precautions, and goals of each person. They also should be of sufficient intensity, volume, and duration in order to achieve maximal benefits.
