Hamstring strain

Back to dictionary

In plain language

An injury to posterior thigh muscle or tendon ranges from minor fiber damage to complete tearing.

01

Clinical Significance & Management

Distinguish muscle injury from proximal tendon avulsion, which may need surgery.

02

Symptoms & Clinical Presentation

1

Sudden posterior thigh pain, tenderness, bruising or weakness.

03

Etiology & Injury Mechanisms

  • Sprinting, kicking or forceful stretch; fatigue and prior injury increase risk.
04

Diagnostics & Imaging Guide

History and strength examination; MRI for suspected major tear and X-ray for bony avulsion.

05

Treatment Options

Option 1

Protect briefly, modify load and rebuild strength; assess severe avulsions with a specialist.

06

Rehabilitation Milestones & Timeline

Rehabilitation depends on the diagnosis, procedure and associated injuries. Progression requires assessment of healing, symptoms and function; elapsed time or a single test cannot determine readiness for sport.

Rehabilitation progression

Progress walking and light exercise to eccentric strength and acceleration according to function.

Red Flags & Urgent Warnings

Seek immediate emergency or specialist orthopaedic evaluation if any of the following occur:

A palpable defect, extensive bruising, inability to walk or neurological symptoms needs prompt assessment.

07

Evidence-Based Clarifications

Comfortable walking does not establish readiness for sprinting.
