Hamstring strains account for 25% to 30% of all muscle strains and are an exceedingly common injury in the athletic population. Although proximal hamstring avulsion injuries occur less commonly than strains at the myotendinous junction, they are more severe and debilitating. Proximal hamstring avulsions do not respond well to conservative treatment and are more likely to require surgical intervention. Surgical repair of proximal hamstring avulsions is indicated when the injury fails to respond to conservative treatment, in cases of osseous avulsion with retraction, and in cases of tearing of all 3 hamstring tendons. Endoscopic repair of proximal hamstring avulsions is a promising technique to repair these injuries while reducing morbidity. We describe our technique for endoscopic proximal hamstring repair, which uses a double-row suture bridge construct to reattach the tendons to the ischial tuberosity.

Objective: This study aimed to validate the ultrasound speckle tracking (UST) algorithm, determine the optimal probe location by comparing normalized cross-correlation (NCC) values of muscle displacement at two locations (proximal vs. middle) of the biceps femoris long head (BFlh) using the UST, and investigate the effects of Nordic hamstring curl exercise (NHE) training on BFlh displacement.
Methods: UST efficacy was verified with ex vivo uniaxial testing of porcine leg muscles.

Department of Sports Surgery, Clinique du sport, Paris, France.
Purpose: To evaluate the functional outcomes of surgical treatment for proximal hamstring avulsion injuries in patients aged over 50 years and to compare the results across another matched group of patients under 50.
Methods: This was a retrospective analysis of prospectively collected data in a matched case-control design targeting patients with proximal hamstring avulsion injuries who underwent surgical treatment at a sports surgery referral centre. Patients over 50 years with complete avulsion or partial injury (>2 cm retraction) were included.

Center for Musculoskeletal Surgery, Charité Universitätsmedizin Berlin, Augustenburger Platz 1, 13353, Berlin, Germany.
Purpose: The purpose of this study was to assess clinical and radiological outcome in patients after proximal hamstring tendon repair. We hypothesized that there is a significant correlation among subjective clinical outcome and interlimb asymmetries in muscle strength, fatty infiltration, and hamstring volume.
Methods: This retrospective monocentric case series included patients with surgical repair after proximal hamstring tendon rupture.

With the remarkable advances in diagnostic ultrasound equipment, there is a growing need for ultrasound diagnosis of muscle and soft tissue injuries in sports injuries. Among these, hamstring strains are often difficult to treat and require early and accurate diagnosis. Injuries to the proximal part of the hamstring often take a long time to heal.

Purpose: To investigate the relationship between the distribution and severity of hypertonicity and spasticity on walking speed in people with neurological injuries.
Material/methods: This cross-sectional observation cohort study used the Modified Ashworth Scale (MAS) and Modified Tardieu Scale (MTS) to assess hypertonicity and spasticity of the gastrocnemius, soleus, hamstrings and quadriceps. Participants were classified as having a distal (gastrocnemius and/or soleus), proximal (hamstrings and/or quadriceps) or mixed distribution of hypertonicity or spasticity.
