hipflexor

Hip flexors refer to a group of muscles located in the anterior hip and thigh that generate hip flexion, the motion that brings the thigh toward the torso. The primary hip flexor is the iliopsoas, composed of the psoas major and iliacus. Other muscles that contribute to hip flexion include the rectus femoris, sartorius, tensor fasciae latae, and pectineus. These muscles cross the hip joint and, in several cases, also cross the knee, enabling complex movements and pelvic stabilization.

Functionally, the hip flexors raise the thigh and help stabilize the pelvis during walking, running, and kicking. They assist in movements that require bending at the hip, and their activity can influence pelvic tilt and posture. The specific action of each muscle varies with hip position and loading.

Injury to the hip flexors is common in sports that involve rapid acceleration, kicking, twisting, or forced hip movements. A typical hip flexor strain presents as groin or front hip pain, tenderness near the hip crease, and weakness with resisted hip flexion. More severe injuries can include contusions or avulsion injuries at the pelvis or muscle attachments. Diagnosis is usually clinical, supported by imaging such as MRI or ultrasound when symptoms persist or to rule out other injuries.

Treatment focuses on rest and a gradual rehabilitation program emphasizing gentle stretching and progressive strengthening. Early in recovery, avoid aggressive stretching; as healing progresses, incorporate functional drills and sport-specific activities. Prevention centers on proper warm-up, balanced strength and flexibility training, and correct technique to reduce strain and imbalances. Most cases improve within weeks to a few months with appropriate care.
