Study Notes
Hip and Pelvis Anatomy and Function
- The hip and pelvis act as a vital connection between the axial skeleton (central body) and appendicular skeleton (limbs).
- Four key functions include: acting as a lever for propulsion, transferring force between upper and lower body, facilitating multidirectional movement, and bearing weight.
Pelvic Structures
- Five major structures form the pelvis: ilium, sacrum, coccyx, pubis, and ischium.
- Additional features include: iliac crest, iliac fossa, ASIS, AIIS, obturator foramen, acetabulum, and PSIS.
Hip and Pelvic Joints
- Three crucial joints connect the hip and pelvis: femoroacetabular joint, pubic symphysis, and sacroiliac joint.
- Femoroacetabular Joint: The primary hip joint where the femoral head meets the acetabulum.
- Pubic Symphysis: Cartilaginous joint between pubic bones, aiding shock absorption and force dissipation. Its movement capability is limited, and it is not a synovial joint.
- Sacroiliac Joint: A strong, weight-bearing synovial joint that links the lower limb to the vertebral column, transmitting forces. It is a gliding joint.
Connective Tissues
- Three key ligaments support the hip joint: iliofemoral, ischiofemoral (posterior), and pubofemoral (anterior) ligaments.
Hip Movements
- Hip movements consist of flexion, extension, abduction, adduction, anterior pelvic rotation, and posterior pelvic rotation.
Hip Muscles (Flexion)
- Iliopsoas, rectus femoris, sartorius, pectineus, and tensor fasciae latae (TFL) muscles.
Hip Muscles (Extension)
- Gluteus maximus, biceps femoris (long head), semimembranosus, and semitendinosus.
Hip Muscles (Adduction)
- Adductors (longus, magnus, brevis), pectineus, and gracilis.
Hip Muscles (Abduction)
- Gluteus medius, gluteus maximus, and tensor fasciae latae (TFL).
Muscle Function Summary
- Anterior hip muscles primarily drive flexion.
- Posterior hip muscles primarily drive extension.
- Medial hip muscles primarily drive adduction.
- Lateral hip muscles primarily drive abduction.
Iliopsoas Muscle
- This composite muscle consists of two parts:
- Iliacus (originates from the iliac fossa)
- Psoas (originates from lumbar vertebrae)
Gluteus Maximus
- Origin: Ilium crest, sacrum, and coccyx.
- Insertion: Lateral greater trochanter and iliotibial band.
Gluteus Medius
- Origin: Lateral surface of ilium below the crest.
- Insertion: Greater trochanter (posterior).
Gluteus Minimus
- Origin: Lateral surface of ilium below the crest.
- Insertion: Greater trochanter (anterior).
Lombard's Paradox
- Co-contraction of opposing muscles during movement.
Hip Bursitis
- Inflammation of a fluid-filled sac (bursa) surrounding the hip joint usually from overuse or trauma.
Bursitis Treatment
- RICE protocol can be used (Rest, Ice, Compression, Elevation), Non-steroidal anti-inflammatory drugs (NSAIDs). Aspiration of fluid from the bursa, and potential corticosteroid injection.
