  • Slide 16
  • Comparison of Male and Female Pelves Female Light and thin Shallow Larger and more oval Small and faces anteriorly Oval Greater than 90 angle Male Heavy and Thick Deep Smaller, heart-shaped Large and faces laterally Round Less than 90 angle
  • Slide 17
  • Comparison of Male and Female Pelves Iliac crest less curved Ilium less vertical Greater sciatic notch wide Coccyx more movable and more curved anteriorly Sacrum shorter, wider and more curved anteriorly Iliac crest more curved Ilium more vertical Greater sciatic notch narrow Coccyx less movable and less curved anteriorly Sacrum longer, narrower and less curved anteriorly
  • Slide 18
  • Comparison of Male and Female Pelves Pelvic outlet wider Ischial Tuberosity shorter, farther apart, and more laterally projecting Pelvic outlet narrower Ischial Tuberosity longer, closer together, and more medially projecting
  • Slide 19

  • Slide 21
  • Slide 22
  • Patellofemoral Stress Syndrome A.K.A. Runners knee. During normal flexion and extension of the knee, the patella tracks (glides) up and down in the groove between the femoral condyles. The patella tracks laterally, which causes increased pressure on the joint. Pain occurs around or under the patella.
