Presentation Transcript

  1. The Hip

  2. Bones of the Hip • Coxal Bone – hip bone composed of 3 fused bones: 1. Ilium 2. Ischium 3. Pubis The 3 bones fuse at the acetabulum – receives the head of the femur

  3. Motions of the Hip Joint Hip Flexion Hip Extension Hip Adduction Hip Abduction

  4. Exercises that work the Hip Flexors include: Exercises that work the Hip Flexors include: Sit-ups Sit-ups Hanging leg raises Hanging leg raises Leg raises Leg raises Resisted hip flexion Resisted hip flexion Muscles of the Hip JointHIP FLEXORS • Hip Flexors (3): - Iliopsoas Muscles: 1. Iliacus 2. Psoas Major 3. Rectus Femoris a hip flexor as well as a knee extensor

  5. Exercises that work the hip flexors: - situps - leg raises - hanging leg raises HIP FLEXORS - Iliopsoas

  6. Hip Extensor Muscles • Gluteus Maximus – main extensors • Hamstring muscles – cannot flex the knee and extend the thigh fully at the same time

  7. Hip Adductors • Adductor Longus • Adductor Brevis • Adductor Magnus • Gracilis • Pectineus

  8. Flexors and Adductors Hip Flexion Adduction

  9. Hip Abductors 1. Gluteus Medius 2. Gluteus Minimus

  10. 3. Tensor Fascia Lata Muscle - inserts into the Iliotibial Band. Helps to stabilize the hip joint

  11. Borders: Inguinal Ligament Sartorius Adductor longus Contents: Femoral Vein Femoral Artery Femoral Nerve The Femoral Triangle

  12. Characteristics of Male Pelvis : Bone are taller, heavier, and thicker More prominent bone markings Obturator foramen is round Pubic arch v-shaped Pelvic inlet heart-shaped Smaller pelvic outlet smaller Ischipubic rami is more everted Sciatic notch is narrower Subpubic arch is more acute Ischial spine is projected inwards Acetabulum is larger Characteristics of Female Pelvis : Bones are lighter and less dense Wider / shallower profile Larger superior and inferior apertures Obturator foramen is oval Pubic arch wider Pelvic inlet oval-shaped Ischiopubic rami is less everted Sciatic notch is wider Subpubic arch is wider Ischial spine is projected outwards Acetabulum is smaller Differences Between Male and Female Pelvis

  13. Greater Sciatic Notch <90o ~90o

  14. HIP Injuries

  15. Kesler Requires Hip Surgery after bone-crushing checks Hamhuis hip-checks Lucic: http://www.youtube.com/watch?v=uIa81l1FsT0

  16. 1. Pelvic Ring Fractures Symphysis 'As I gave birth, I felt my pelvis split'

  17. Treatment:

  18. 2. Sacral Fractures

  19. Sacral fracture patterns are commonly categorized using the Denis classification system.3 The Denis classification divides the sacrum into 3 zones (Figure 2). Zone 1 fractures are lateral to the neural foramina, Zone 2 fracture pass through the foramina, and Zone 3 fractures are medial to the foramen and involve the spinal canal.

  20. Treatment:

  21. 3. Hip Dislocations

  24. 3. Acetabular Fractures

  25. The Hip Joint

  26. 4a. Femoral Fractures

  27. 4b. Femoral Neck Fractures

  28. 5. Hip Pointer

  29. 6a. Avulsion of Lesser Trochanter of Femur • Forceful Strain of Ilioposas muscle

  30. 6b. Avulsion of Ischial Tuberosity • Forceful stretch of Hamstring muscles

  31. 8. Avulsion of Anterior Superior Iliac Spine (ASIS) • Origin of the Sartorius muscle

  32. 6c. Avulsion of Crest of Ilium • Forceful contraction of the abdominal muscle

  33. The Abdominal Muscles • Rectus Abdominus trunk flexion • Internal Oblique rotates trunk to same side • External oblique rotates trunk to opposite side
