  1. Pelvic Fractures.
  2. Acetabular Fractures
  3. Dislocation Of Hip Joint
  4. Fracture of proximal Femur
  5. Fracture of Distal Femur
  6. Fracure of Patella
  7. Tibila or Fibular Fractures

A. Classification of pelvic fracture:

  • 1.Anteroposterior compression Fractures
  • 2.Vertical shear Fracture

Complications of Pelvic Fractures :

  1. Massive Bleeding
  2. Fracture itself.
  3. Superior Gluteal Artery.
  4. Sciatic Nerve.
  5. SI Joint
  6. Hypovolmia 
  7. Shock

B. Acetabular fractures : Acetabular fractures occur primarily in young adults as a result of high energy trauma.Malunion of the acetabular fracture will lead to post traumatic arthritis.

C. Dislocation of the hip joint :


Posterior dislocation :

•Most common type of dislocation.
•Femoral head is lateral & superior to acetabulum
•Posterior rim of acetabulum is usually fractured
•Associated sciatic nerve injury in 10%

Anterior dislocation :

•Femoral head displaced into the obturator, pubic or iliac region

Internal dislocation :

•Always associated with acetabular fracture
•Femoral head protrudes into the pelvic cavity.
D. Fractures of the proximal femur :


1. Intracapsular fractures involving femoral head or neck:

—  Capital: uncommon
—  Subcapital: common
—  Transcervical: uncommon

2. Extracapsular fractures involving the trochanters :

—  Intertrochanteric
—  Subtrochanteric
E. Fractures of distal femur :



—Non displaced



F. Fracture patella

 G. Tibia or Fibula Fractures Types:
