Coxa Valga
angle >140 degrees
Normal femur head angle
126-139 degrees
Anterversion
shaft of femur is rotated medially due to an increase in the torsion of the femoral neck
Anterversion could result in:
genu valgium and pes planus
Retroversion
shaft of the femur is rotated laterally due to a decrease in torsion of the femoral neck
Slouched posture results in shortened:
rectus femoris and hamstring
Slouched posture results in general limitation of:
hip rotation
Slouched posture results in:
Hip flexors during gait
- contract concentrically to initiate swing
Hip extensors during gait
- gluteus maximus initiates hip extension
Hip abductors
Flat back posture:
shortened rectus femoris, IT band and gluteus maximus
Associated LE compensations of slouched posture
hip extension, medial rotation of the femur, genu recurvatum, genu varum, pes valgus
Genu valgum
knock knees
genu varum
bowleggedness
Painful hip syndromes/overuse syndromes
Common impairment
Post operative risks of THA
-DVT, pneumonia, infection
Anterior THA Approach (Smith-Peterson)
Traditional Anterolateral THA Approach (Watson-Jones)
Minimally Invasive or Muscle Sparing Anterolateral THA Approach
Lateral or Tranctrochanteric THA Approach
Posterolateral THA approach
-does not affect the gluteal med
Posterior THA Approach
highest rate of dislocation
