Question
1. Identify several factors that might predispose someone to a femoral neck fracture.
2. Which knee joint ligaments contribute to anterior-posterior stability of the knee joint? Which ligaments contribute to medial-lateral stability of the knee joint?
3.Identify the ligaments that support the tibiofibular joints. Describe the ligaments that support the ankle joint, including the names of components when relevant.
4.Describe the function of the intervertebral disk during motion and in weight-bearing. ?
5.Describe the subdivisions of the stance and swing phases of the walking gait cycle, using the traditional terminology.
Explanation / Answer
1. femoral neck fracture also called as hip joint fracture.maily seen in elderly person(reduces bone mineral density,unsteady gait)
various risk factors are:osteoporotic women
smoking
physical inactivity
female sex with increasing age
arthritis
low BMI
2.Anterior-posterior stability to knee joint given by:cruciate ligament(present in pair)
medial-lateral stability to knee joint given by:collateral ligament(present in pair)
3.ligament support tibiofibular joint:
-anterior,posterior proximal tibiofibular joint which strenthen joint capsule
-biceps femoris and lateral collateral ligament also provide additional support
ligament support ankle joint
-strong deltoid ligament
-3 lateral: anterior talofibular
posterior talofibular
calcaneofibular
4.Intervetebral disk allows vetebra to tilt which increases range of motion.also it act as catilagenous joint in which slightly movement seen act as ligament for holding vetebre in place.Act as shock absorber.
5.subdivision of stance phase
heel contact:initial stage
foot float:loading response
midstance:greater tronchanter in alignment
heel-off:terminal phase of stance
toe-off:pre swing stage
subdivision of swing phase
acceleration:initial stage
midswing:swingging limbs overtakes limb in stance
deceleration:terminal stage
