Iliopsoas muscle tear: what to know

The iliopsoas group helps bring the thigh toward the body and stabilise the hip and lower back. A forceful sprint, kick, fall, sudden change of direction, or heavy effort can injure its fibres. A tear may produce a sharp pain, bruising, tenderness, a limp, or difficulty climbing stairs and getting into a car. Some injuries are partial, while more extensive damage can affect strength and function considerably.

Assessment includes the injury story, hip movement, strength, and checks for back or joint causes. Ultrasound or MRI may be considered when the extent of damage is unclear or recovery is not following the expected pattern.

Stop sprinting, kicking, heavy lifting, and any movement that causes sharp pain. Protect the area without staying immobile for long periods; gentle walking is suitable only if it is comfortable and does not worsen the limp. Cold therapy with a cloth barrier may ease early discomfort. Do not force stretching, deep massage, or a rapid return to sport. Rehabilitation commonly progresses from comfortable motion to controlled strengthening and then sport-specific loading under guidance.

Arrange prompt assessment for sudden weakness, a significant limp, bruising, or pain that prevents normal walking. Seek urgent care after major trauma if you cannot bear weight or the pain is severe. Numbness, new bladder or bowel problems, or severe lower-back pain require urgent evaluation because they may indicate a condition beyond an iliopsoas injury.

Ask whether the injury appears partial or extensive, whether imaging would change management, and which movements are safe. Clarify the milestones for driving, work, exercise, and a gradual return to sport.
