Bones of the Lower Limb: Femur and Patella01:16

Bones of the Lower Limb: Femur and Patella

9.2K
The femur is the body's longest and strongest bone spanning the thigh region. Its head articulates with the acetabulum of the hip bone to form the hip joint. A minor indentation on the medial side of the femoral head, called the fovea capitis, serves as the site of attachment for the ligament of the head of the femur. This weak ligament spans the femur and acetabulum and supports the hip joint. The narrowed region below the head is the neck of the femur. The inclination angle between the...

Muscles that Move the Thigh

3.5K
The thigh's motion is primarily governed by muscles originating in the pelvic girdle and inserted into the femur. One crucial muscle, the iliopsoas, is a combination of the psoas major and the iliacus muscles, sharing a common insertion point on the lesser trochanter of the femur.
Three other significant muscles are the gluteus maximus, gluteus medius, and gluteus minimus. The gluteus maximus originates from the posterior surface of the ilium, sacrum, and coccyx, and the thoracolumbar...

Summary
This summary is machine-generated.

Snapping hip, or coxa saltans, involves a snapping sensation in the hip. Ultrasound aids in diagnosing extra-articular snapping by visualizing tendon movement during hip motion.

Area of Science:

  • Orthopedics
  • Sports Medicine
  • Diagnostic Imaging

Background:

  • Snapping hip, or coxa saltans, is characterized by a palpable or audible snap during hip movement.
  • Extra-articular snapping has external (iliotibial band) and internal (iliopsoas tendon) causes.
  • Differentiating internal snapping hip from intra-articular causes can be challenging.

Purpose of the Study:

  • To evaluate the utility of ultrasound in diagnosing extra-articular snapping hip.
  • To illustrate the dynamic visualization of tendon translation using ultrasound.

Main Methods:

  • Dynamic ultrasound assessment of hip joint movement.
  • Observational analysis of iliotibial band and iliopsoas tendon motion.

Main Results:

  • Ultrasound effectively visualizes dynamic tendon translation during hip flexion and extension.
  • This modality supports the diagnosis of external (iliotibial band) and internal (iliopsoas tendon) snapping hip.
  • Ultrasound can help distinguish between extra-articular and intra-articular causes.

Conclusions:

  • Ultrasound is a valuable tool for the dynamic diagnosis of extra-articular snapping hip.
  • Conservative management, including anti-inflammatories and physical therapy, is the primary treatment.
  • Surgical intervention may be considered for recalcitrant cases to address iliopsoas or iliotibial band issues.
