Background The early repair of acute proximal hamstring ruptures provides better clinical results than delayed repair. However, it is unclear how nonoperative treatment compares with the operative treatment of these injuries. Purpose To compare the clinical results of the nonoperative and operative treatment of acute proximal hamstring ruptures. Study Design Cohort study; Level of evidence,...

Muscular flexibility is an important aspect of normal human function. Limited flexibility has been shown to predispose a person to several musculoskeletal overuse injuries and significantly affects a person’s level of function [1]. Muscular tightness is frequently postulated as an intrinsic risk factor for the development of a muscle injury. Lack of flexibility has been suggested as a predispos...

Neuromusculoskeletal models are used to investigate hamstring mechanics during sprinting. We show that peak hamstring stretch occurs during late swing phase and is invariant with speed, but does depend on tendon compliance and the action of other muscles in the lumbopelvic region. The insights gained are relevant for improving the scientific basis of hamstring strain injury prevention and rehab...

Partial tears of the proximal hamstring tendon can successfully be managed with tendon repair in cases of failed conservative management. As in partial-thickness gluteus medius repair, a transtendinous technique can be used to repair partial-thickness undersurface tears of the hamstring origin. This report details an endoscopic transtendinous approach for the treatment of partial-thickness hams...

BACKGROUND The purpose of this study was to assess postsurgical outcomes in active patients after primary repair of acute and chronic proximal hamstring tears. HYPOTHESIS Surgical treatment of both acute and chronic proximal hamstring avulsion injuries would result in improved patient outcomes using validated outcome scores and a hamstring-specific questionnaire, and operative repair of these...

Hamstring strain injuries are one of the most common injuries in team sports that involve running, especially soccer, Australian football, rugby and field hockey (30–40 %) [9, 19]. As such, hamstring strain injuries are a common area of investigation in sports medicine with goals of reducing the incidence but also the time away from sport following an injury. The majority of research to date ha...

BACKGROUND High-grade partial proximal hamstring tears and complete tears with retraction less than 2 cm are a subset of proximal hamstring injuries where, historically, treatment has been nonoperative. It is unknown how nonoperative treatment compares with operative treatment. HYPOTHESIS The clinical and functional outcomes of nonoperative and operative treatment of partial/complete proximal...

BACKGROUND Acute hamstring re-injuries are common and hard to predict. The aim of this study was to investigate the association between clinical and imaging findings and the occurrence of hamstring re-injuries. METHODS We obtained baseline data (clinical and MRI findings) of athletes who sustained an acute hamstring injury within 5 days of initial injury. We also collected data of standardise...

BACKGROUND Hamstring injury is one of the most common injuries affecting gaelic footballers, similar to other field sports. Research in other sports on whether residual hamstring weakness is present after hamstring injury is inconsistent, and no study has examined this factor in irish gaelic footballers. The aim of this study was to examine whether significant knee muscle weakness is present in...
