ObjectiveTo evaluate the imaging findings following acute hamstring injury.Design and patientsWe retrospectively reviewed the imaging findings of hamstring muscle complex (HMC) strain in 170 patients referred to our institution over a 3-year period. A total of 179 injuries to the HMC were demonstrated in 170 patients (154 male, 16 female, mean age 28.2 years). The mean duration of symptoms was 4.7 days (range 1–10 days). MR imaging was performed in 97 cases and sonography in 102 cases (both… 

Avulsion of the proximal hamstring origin.

It is suggested that, in cases of complete avulsion with hamstring retraction, a delay in surgical repair renders the repair more technically challenging, may increase the likelihood of sciatic nerve involvement, increases the need for postoperative bracing, and reduces postoperative outcome in terms of hamstring strength and endurance.

Magnetic resonance imaging findings of injuries to the calf muscle complex

This retrospective study utilizing MRI demonstrates that the medial head of the gastrocnemius is the most commonly injured muscle of the calf, closely followed by the soleus, the latter finding rarely reported in the sonographic literature.

Proximal hamstring tendon avulsion: state of the art

The authors provide a detailed description of what would be considered the current worldwide standard of care; an open, suture-anchor-based repair of the avulsed tendon complex (semitendinosus, long head of biceps femoris and semimembranosus) securely to the ischial tuberosity.

Hamstring injuries: anatomy, imaging, and intervention.

Imaging has a role in confirming the site of injury and characterizing its extent, providing some prognostic information and helping plan treatment, and there is increasing interest in the use of growth factors to accelerate healing after muscle and tendon injury.

[Avulsion of the Proximal Hamstring Insertion. Case Reports].

Three cases of proximal hamstring avulsion, two complete and one partial ruptures of the biceps femoris muscle are presented, two free of any symptoms at 6 months after surgery and the last had pain in the subgluteal area and a mild deficit in hamstring strength.

Evaluation and Imaging of an Untreated Grade III Hamstring Tear: A Case Report

The case of a 26-year-old man who presented 1 year after a noncontact, left-sided proximal hamstring tear incurred while sprinting suggests a benign natural history for this injury and the appropriateness of noninvasive treatment.

Functional outcome after repair of proximal hamstring avulsions.

Repairs of a symptomatic and displaced ruptured proximal hamstring tendon yields good subjective and objective functional results with minimal complications.

Hamstring avulsion injuries

The current and more aggressive approach incorporates a surgical procedure, which leads to the best possible outcome for athletes with complete hamstring avulsions from the ischial insertion.

Partial rupture of the hamstring muscle complex: a literature review on treatment options

A case of a chronic severe partial injury to the HMC managed conservatively in a 49-year old female is presented to illustrate the level of function that can be achieved after non-operative management and the need for re-evaluation in treatment options in partial hamstring muscle ruptures.

Hamstring Muscle Complex : An Imaging Review 1

A thorough knowledge of the HMC anatomy and of the spectrum of imaging findings in HMC injury is crucial for providing optimal patient care and will enable the musculoskeletal radiologist to make an accurate and useful contribution to the treatment of athletes at all levels of participation.



MR imaging of the distribution and location of acute hamstring injuries in athletes.

The biceps femoris is the most commonly injured hamstring muscle and the semitendinosus is the second most commonlyjured muscle.

Hamstring Muscle Injuries Among Water Skiers

The mechanism of injury was identical in five of six novice skiers and each sus tained the injury while attempting to get up on one or two skis from a submerged position, while in contrast, the expert skiers all sustained injury secondary to a fall while skiing.

Hamstring injuries: radiographic, conventional tomographic, CT, and MR imaging characteristics.

Familiarity with the variable appearance of hamstring injuries over time and with different modalities facilitates accurate characterization.

MR imaging in the prognostication of hamstring injury. Work in progress.

Prediction of CI for high-performance athletes with complete hamstring injury may be accomplished with use of MR imaging and poor prognostic factors.

Computed tomography of hamstring muscle strains.

Injuries were seen most commonly in the proximal and lateral portions of the hamstring muscle group, particularly in the biceps femoris, suggesting inflammation and edema are the major component of injury, not bleeding as commonly assumed.

Prophylaxis and management of hamstring muscle injuries in intercollegiate football players

Isokinetic testing and rehabilita tion of muscle imbalances can prevent hamstring strains and stimulate it to heal with higher tensile strength during the critical healing period resulting in less like recurrences.

Radiographic imaging of muscle strain injury

Low-up computed tomographic and magnetic resonance imaging studies can clearly demonstrate atrophy, fibrosis, and calcium deposition, and Muscle tissue remote from the myoten dinous junction clearly demonstrates extensive injury with abundant magnetic resonance Imaging signal changes consistent with edema and inflammation.

Complete rupture of the distal semimembranosus tendon with secondary hamstring muscles atrophy: MR findings in two cases

Two cases of complete rupture of the distal semimenbranosus tendon are presented, which clinically presented as soft-tissue masses and MR imaging permitted the correct diagnosis.

Magnetic resonance findings in skeletal muscle tears

MR imaging has a limited, but occasionally important role in selected patients with skeletal muscle tears, and can identify the cause of the pain and exclude a neoplasm by proving that the mass is a hypertrophied or retracted muscle.

Biomechanical and histological evaluation of muscle after controlled strain injury

Findings suggest that decreasing muscle function seen clinically between 24 and 48 hours following strain injury may result from pain due to inflammation, andScarring and fibrosis seen at 7 days may explain the frequent recur rence of injury to strained muscles.
