Intramuscular injection in gluteal region. Commonest Cause 2. Greater trochanter fracture. 3. Posterior hip joint dislocation. Commonest site Supero-medial quadrant of the gluteal region. Deformity Limp (Waddling Gait) (Gluteal Gait) (Lurching Gait). 1. Gluteus medius. Muscles paralyzed 2. Gluteus minimus. 3. Tensor fascia latae. 1) Abduction of thigh. Motor loss 2) Medial rotation of thigh.

Movements of Lower Limb By Dr. Hassan Rezk October 19, 2024 15  Injury of Sciatic Nerve 1) Lumbar disc prolapse (herniation). LOWER LIMB Commonest 2) Piriformis Syndrome: spasm in piriformis e.g.: ice skaters, cyclists, and rock climbers Cause 3) Stab wound in the gluteal region or posterior compartment of thigh. Commonest Any part of its course. site 1. Hamstring muscles. Muscles 2. All leg muscles. paralyzed 3. All foot muscles. 1. Extension of hip (Gluteus maximus is still functioning especially if the injury is away from inferior gluteal nerve). Motor loss 2. Flexion of knee (sartorius & Gracilis are still functioning). 3. Dorsiflexion, plantarflexion, inversion & eversion of foot. Movements of Lower Limb By Dr. Hassan Rezk October 19, 2024 16  Injury of Common Peroneal Nerve LOWER LIMB Commonest Cause Fracture neck of fibula. Commonest site At lateral aspect of knee joint. ▪ Foot drop (plantarflexed and inverted) ▪ This has the effect of making the limb Deformity “too long” ▪ Associated with stepping gait. Muscles Anterior and lateral compartments of leg. paralyzed Motor loss Dorsiflexion & eversion. Movements of Lower Limb By Dr. Hassan Rezk October 19, 2024 17  Case Scenario (Staff Question) https://www.youtube.com/watch?v=7Ft1bUTzxkM A 45-year-old male presents to the clinic with difficulty lifting the front part of his foot after lifting a LOWER LIMB heavy object, causing him to trip frequently. He reports that this started after he experienced a sharp pain in his lower back that radiated down his leg. On examination, he has a high-stepping gait and cannot dorsiflex his foot. Sensation is reduced over the dorsum of the foot and the lateral aspect of the lower leg. What is the most common cause of foot drop in this patient? A. Herniated lumbar disc B. Hip fracture C. Knee dislocation D. Ankle sprain Movements of Lower Limb By Dr. Hassan Rezk October 19, 2024 18 LOWER LIMB Reference ISBN: 978-0-7020-5131-9 ISBN: 978-07817-7525-0 ISBN: 978-1-60913-446-4 Copyright© 2015, 2010, 2005 by Copyright© 2010, by Lippincott Copyright© 2012, by Lippincott Churchill Livingstone, an imprint of Williams & Wilkins, a Wolters Williams & Wilkins, a Wolters Elsevier Inc.
