Hip Anatomy & Ligaments
This type of joint is found at the hip, allowing for multidirectional movement.
What is a ball-and-socket joint?
The iliopsoas, rectus femoris, and TFL are prime movers for this hip motion.
What is hip flexion?
A leg length discrepancy, such as a unilateral short leg, can cause this abnormal pelvic motion.
What is lateral pelvic tilting?
This non-operative treatment for hip osteoarthritis involves mobilizing the joint and improving soft tissue mobility.
What is Grade III or IV oscillation techniques?
This nerve, originating from the sacral plexus, is responsible for sensation and motor function in the hip and buttock area.
What is the sciatic nerve?
This is the most common arthritic condition affecting the hip joint, often due to aging or trauma.
What is osteoarthritis or degenerative joint disease (DJD)?
This ligament, also known as the "Y-ligament," is the strongest of the hip ligaments and helps prevent hyperextension.
What is the iliofemoral ligament?
These muscles are responsible for hip extension during walking.
What are the gluteus maximus and hamstrings?
This condition results from impaired circulation in the hip joint, leading to degeneration of the femoral head.
What is avascular necrosis?
This surgical procedure stimulates fibrocartilage growth by creating small fractures in the bone at the site of a chondral lesion.
What is microfracture surgery?
This nerve may be entrapped by the piriformis muscle and cause pain or sensory changes along the posterior thigh and leg.
What is the sciatic nerve?
This condition occurs when the blood supply to the femoral head is disrupted, leading to bone and joint degeneration.
What is avascular necrosis?
This ligament helps prevent excessive hip abduction and external rotation.
What is the pubofemoral ligament?
These muscles are responsible for stabilizing the pelvis and preventing a hip drop during gait.
What are the gluteus medius and gluteus minimus?
This condition, commonly seen in women, results from weak hip abductors causing increased stress on the knee.
What is patellofemoral pain syndrome?
A person with hip osteoarthritis would benefit from this type of aerobic activity to reduce joint stress while maintaining fitness.
What is using a stationary bike or pool-based exercises?
Injury or compression of this nerve, often occurring during labor, can cause sensory changes along the medial aspect of the thigh.
What is the obturator nerve?
In hip osteoarthritis, this motion is typically most limited due to the loss of cartilage and joint space.
What is internal rotation of the hip?
The ischiofemoral ligament helps prevent excessive internal rotation and is located on this side of the hip joint.
What is the posterior side of the hip joint?
This motion occurs when the unsupported side of the pelvis moves backward, and the trunk rotates in the opposite direction.
What is posterior pelvic rotation?
Weak hip extensors and abductors can lead to this syndrome, which may compress the sciatic nerve.
What is piriformis syndrome?
This is a common surgical approach for hip replacement where the gluteus maximus is divided and the posterior capsule excised and repaired.
What is the posterior or posterolateral approach?
This nerve provides motor control to the hip flexors, including the iliopsoas, and injury can occur from fractures or dislocations.
What is the femoral nerve?
This posture, often seen in patients with hip hypomobility, results from limited hip extension and can increase forces in the lower back.
What is an antalgic gait or compensation with lumbar extension?
The pelvis and femur are primarily constructed to support this function in the body.
What is upright standing and weight-bearing?
These hip muscles help with internal rotation and are considered secondary movers.
What are the gluteus medius, gluteus minimus, and TFL?
This is a common overuse injury caused by excessive tension on the IT band and can lead to knee pain and hip dysfunction.
What is trochanteric bursitis or IT band friction syndrome?
This hip surgery involves resurfacing the joint with cobalt-chrome and titanium materials and is used for severe joint deterioration.
What is a total hip replacement (THA)?
Referred pain to the hip or buttocks may arise from irritation in these spinal segments.
What are L1, L2, L3, S1, and S2?
A person with osteoarthritis of the hip may experience this type of pain, often referred from the groin and extending along the anterior thigh to the knee.
What is groin pain or referred pain in the L3 dermatome?
