OBJECTIVE: To assess the rates and timing of return to sport for the surgical management of proximal hamstring avulsions (PHAs). METHODS: Three databases, PubMed, MEDLINE, and EMBASE, were searched from database inception until October 7, 2017, by 2 reviewers independently and in duplicate. The inclusion criteria were studies reporting return to sport outcomes for surgical management of acute, chronic, complete, and partial PHA. The rate of return to sports was combined in a meta-analysis of proportions using a random-effects model...

Heterotrophic ossification (HO) is a well-described phenomenon in patients with spinal cord injury, head injury, burns, hip replacement, and general trauma. However, it has also been described through a relative paucity of case reports that repeated microtrauma from the use of weight-bearing leg prostheses is an additional possible cause of HO. In our case, we examine a patient who developed an extreme case of HO after he began an exercise regimen with assistance from a running limb. This abnormal formation was actually advantageous because it created a more snug fit of the prosthetic device and improved the patient's ability to run...

This article presents a brief, focused physical examination [PE, the Buffalo Concussion Physical Examination (BCPE)] for sport-related concussion (SRC) to be considered for use in the outpatient setting by sports medicine physicians, pediatricians, and primary-care physicians. This companion paper describes how to perform the PE, which was derived in a separate study presented in this journal. It is envisioned for use at the initial and follow-up outpatient visits both for acute concussions and in patients with prolonged symptoms...

For high-level athletes, most experts consider that 1-level arthrodesis in cervical spine surgery does not prevent return to play. Nevertheless, return remains controversial in cases of 2-level fusions. We report the case of a 27-year-old professional rugby player. He had had a double cervical fusion C5C6 and C6C7 for cervical hernia and was allowed to continue rugby activities afterward. Four years after this surgery, his neck was forced in hyperflexion during a match and complete tetraplegia occurred. A computed tomography scan showed a C3C4 unilateral facet dislocation...

OBJECTIVE: Liver cancer is the second most common cause of death from cancer. Physical activity (PA) was found to be associated with lower risks of several types of cancer. However, the association between PA and the risk of liver cancer is still inconclusive. This systematic review and meta-analysis was aiming to summarize the association between PA and liver cancer risk. METHODS: Literatures related were identified by searching PubMed, EMBASE, and Chinese Biomedical literature database from 1965 to 2017 without language limitation...

BACKGROUND: Achilles and patellar tendinopathy are common in runners. Despite the relevance of the problem, causative factors remain poorly understood. This cross-sectional study evaluated the association between Achilles and patellar tendinopathy and age, sex, weight, height, number of marathons, and impact profile in runners who participated in the 2017 Marathon of Rome. METHODS: At the 2017 Marathon of Rome, 350 athletes (256 men and 94 women; mean age: 44.8 years, range 12-80 years) filled in the VISA-A and VISA-P questionnaires...

OBJECTIVE: To analyze the effect of cryotherapy on muscle stiffness after exercise-induced muscle damage. DESIGN: A leg-to-leg comparison model. SETTING: University research laboratory. PARTICIPANTS: Thirty (30) untrained men (21.1 ± 1.6 years, 177.6 ± 6.4 cm, 75.9 ± 10.0 kg, and 15.9 ± 2.9% fat mass) with no history of lower-limb injury and no experience in resistance training. INTERVENTION: All participants underwent a plyometric exercise program to induce muscle damage; however, randomly, one leg was assigned to a treatment condition and subjected twice to cold-water immersion of the lower limb at 10°C (±1°C) for 10 minutes, while the other leg was assigned to control...

OBJECTIVES: This study estimates the prevalence of allergic diseases in a group of Italian elite mountain bikers, compares the prevalence of infectious episodes between allergic and nonallergic athletes, and evaluates asthma and rhinitis symptom control in allergic athletes. DESIGN: Two hundred twenty-six Italian nonsmoking mountain bikers received by mail the Allergy Questionnaire for Athletes (AQUA) and completed it. The RhinAsthma Patient Perspective (RAPP) questionnaire was sent to the 108 participants with a positive AQUA score and 104 returned the questionnaire...
