Partial Rupture of the Hamstring Muscle Complex: a Literature Review on Treatment Options

Injuries of the hamstring muscle complex (HMC) often affect athletes participating in specific sporting activities. Mild injuries that constitute a mere strain of the muscle can be managed symptomatically, while severe injuries often require surgical intervention to precipitate a return to function. Neglected injuries usually result in a long-term functional impairment. Therefore, surgical reconstruction of the HMC is advised for both partial and complete lesions. Without acute repair, a chronic lesion referred to as hamstring syndrome can result due to dysfunction of the HMC. Surgical intervention is usually recommended. 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. The clinical and radiological findings are presented 18 months post-injury along with a review of the current literature. There are no previous reports in the literature describing this scenario. This case indicates the need for re-evaluation in treatment options in partial hamstring muscle ruptures. A surgical treatment of partial rupture should be considered more often as an adequate treatment option and cofactors that influence the prognosis must be revealed. The indication of surgical intervention should be re-evaluated within the first months in case of conservative treatment.
