Hamstring Injuries in Professional Soccer Players: Extent of MRI-Detected Edema and the Time to Return to Play.

Background: Discrepancies exist in the literature regarding the association of the extent of injuries assessed on magnetic resonance imaging (MRI) with recovery times.

Hypothesis: MRI-detected edema in grade 1 hamstring injuries does not affect the return to play (RTP).

Study Design: Retrospective cohort study.

Shock wave therapy associated with eccentric strengthening versus isolated eccentric strengthening for Achilles insertional tendinopathy treatment: a double-blinded randomised clinical trial protocol.

Background: There is no consensus regarding the treatment of Achilles insertional tendinopathies. Eccentric training remains the main choice in the conservative treatment of this illness; however, the good results in the management of non-insertional Achilles tendinopathy were not replicated in the insertional condition. Low energy shock wave therapy has been described as an alternative to these patients, but has yet to be empirically tested.

Rehabilitation Management of Hemicorporectomy.

This is a case report of a 55-year-old woman who was treated with a hemicorporectomy consequent to an invasive undifferentiated sacral chordoma. We describe the clinical course and rehabilitation process in an amputee outpatient clinic and report outcome measures such as the modified Functional Reach Test, the Amputee Mobility Predictor, the Functional Independence Measure, and the Short-Form Health Survey after 9 months of rehabilitation.

An anatomic study of the posterior septum of the knee.

Purpose: To evaluate the posterior septum of the knee and determine the presence of a safe zone that could be removed, without significant damage to blood vessels and nerves.

Methods: Nineteen fresh unpaired adult human cadaveric knees, with no macroscopic degenerative or traumatic changes, were used in this study. Microscopic evaluation was performed by analysis of H&E, CD-34, and S-100 staining.

Bupivacaine injection leads to muscle force reduction and histologic changes in a murine model.

Objective: To evaluate the effect of bupivacaine on muscle force and histology. We hypothesize that bupivacaine will worsen the muscle's physiological activity.

Setting: Controlled laboratory experiment.
