Hamstring rupture
What is Hamstring rupture?
A hamstring rupture may involve one or more tendons at the pelvis, most importantly proximal hamstring avulsions where the tendon pulls away from the sitting bone. These injuries occur during sprinting, water skiing, football, slipping or forced hip flexion with the knee extended.
Common symptoms
Patients may feel a sudden pop in the buttock or back of the thigh, followed by bruising, swelling, pain sitting, weakness, cramping and difficulty running or pushing off. Complete avulsions can cause substantial functional loss.
Diagnosis and imaging
MRI is the key investigation because it shows which tendons are torn, how far they have retracted and whether the sciatic nerve is involved. Examination assesses bruising, tenderness, strength and gait.
Non-surgical treatment
Partial tears, low-grade injuries and lower-demand patients may be treated with pain control, protected activity and physiotherapy. Rehabilitation restores flexibility, strength and running mechanics gradually.
Surgical treatment
Surgery is considered for complete proximal avulsions, significant tendon retraction, multiple tendon injuries, high-demand patients or persistent weakness and pain. Repair aims to restore the tendon attachment and strength.
Recovery and follow-up
After repair, hip flexion and hamstring loading are protected early. Rehabilitation progresses through walking, strengthening and running phases. Return to sport is usually measured in months.
Hamstring rupture FAQs
How do I know if a hamstring injury is a rupture?
Large bruising, a pop, pain sitting, marked weakness or difficulty walking should raise concern for a significant tear and usually warrants MRI.
How is hamstring rupture diagnosed?
Diagnosis starts with a focused history and examination, then uses imaging selectively to confirm the pattern of injury, exclude related problems and plan treatment accurately.
Do all hamstring ruptures need surgery?
No. The decision depends on the number of tendons torn, retraction, function, age, goals and activity level.
Will I need surgery for hamstring rupture?
Many patients improve without surgery. Surgery is considered when symptoms remain limiting despite appropriate non-surgical care, when there is significant structural damage, or when delay may compromise function.
When can I return to running or field sport?
Return depends on the diagnosis, treatment type, tissue healing and the physical demands of the activity. The plan is usually staged, with strength, range of motion and confidence rebuilt before unrestricted loading.
