“…However, it was reported that each of the three units of SM had a specifi c distal insertion site, was innervated by an individual nerve, and performed a specifi c function at the knee joint. Other studies have in some part investigated the morphology [Markee et al, 1955;Garrett et al, 1989;Hayashi and Maruyama, 2001], innervation [Sunderland and Hughes, 1946;Markee et al, 1955;Seidel et al, 1996] or specifi c components of muscle architecture such as fascicle or fi ber length, volume or physiological cross-sectional area (PCSA) [Barrett, 1962;Wickiewicz et al, 1983;Friederich and Brand, 1990;Chelboun et al, 2001], but a complete description of both architecture and innervation was not available for all the hamstring muscles. Therefore, the purpose of this study was to clarify the gross morphology of these muscles, specifi cally to (a) determine whether anatomical partitioning exists, on the basis of architecture and/or innervation; (b) describe the fascicular anatomy, and (c) detail the length and form of their tendons and musculotendinous junctions (MTJs).…”

Knowledge of the anatomical organization of the hamstring muscles is necessary to understand their functions, and to assist in the development of accurate clinical and biomechanical models. The hamstring muscles were examined by dissection in six embalmed human lower limbs with the purpose of clarifying their gross morphology. In addition to obtaining evidence for or against anatomical partitioning (as based on muscle architecture and pattern of innervation), data pertaining to architectural parameters such as fascicular length, volume, physiological cross-sectional area, and tendon length were collected. For each muscle, relatively consistent patterns of innervation were identified between specimens, and each was unique with respect to anatomical organization. On the basis of muscle architecture, three regions were identified within semimembranosus. However, this was not completely congruent with the pattern of innervation, as a primary nerve branch supplied only two regions, with the third region receiving a secondary branch. Semitendinosus comprised two distinct partitions arranged in series that were divided by a tendinous inscription. A singular muscle nerve or a primary nerve branch innervated each partition. In the biceps femoris long head the two regions were supplied via a primary nerve branch which divided into two primary branches or split into a series of branches. Being the only muscle to cross a single joint, biceps femoris short head consisted of two distinct regions demarcated by fiber direction, with each innervated by a separate muscle nerve. Architecturally, each muscle differed with respect to parameters such as physiological cross-sectional area, fascicular length and volume, but generally all partitions within an individual muscle were similar in fascicular length. The long proximal and distal tendons of these muscles extended into the muscle bellies thereby forming elongated musculotendinous junctions.

“…Sprinters and footballers show a high incidence of these injuries [1][2][3][4]. Garrett, Rich and Nikolaou used computed tomography to show that the injuries are primarily localized proximally and laterally in the hamstring group, probably in the long head of the biceps [5].…”

The aim of this study was to determine whether there are any differences in hamstring strength indices of isokinetic concentric and eccentric peak torques at 60 deg/sec and 180 deg/sec between hamstring injured (left / non dominant) and non-injured (right / dominant) leg in a hamstring-injured athlete. A 25-year-old male recreational athlete who had hamstring injury, grade 2, twice in the past took part in the present case study. Hamstring concentric and eccentric peak torques were tested at two velocities: 60 and 180 deg/sec. The only difference was found in concentric peak torque at 60 deg/sec. Future well -designed studies are needed to find out whether there is a relationship between strength testing and hamstring muscle injury.

“…The hamstring muscles are among the most commonly injured muscles in athletes. [1][2][3] Most of these injuries are muscle strains at the myotendinous junction, 4,5 which respond to conservative treatment. 6,7 Injuries to the proximal hamstring origin are less common and were detected in 12% of all hamstring injuries.…”

Hamstring muscle injuries are common in athletes and mostly consist of sprains at the myotendinous junction, which often respond well to conservative treatment. Proximal hamstring avulsion injuries, though less common, can be severely debilitating. This injury is often seen in water skiers but has been described in many other sports and in middleaged patients. Complete avulsions in young and active individuals do not respond well to conservative treatment and may require surgical repair. In contrast, many partial tears may be treated nonoperatively. However, when symptoms continue despite a trial of extensive therapy, surgery may be warranted. Traditional surgery for proximal hamstring repair is performed with the patient in the prone position with an incision made longitudinally or along the gluteal fold, followed by identification of the torn tendons and fixation to the ischial tuberosity. We describe a novel surgical technique for endoscopic repair of proximal hamstring avulsion injuries.
