Orthopedics Flashcards
Define Osteochondrosis
Decreased blood supply to bone, especially the Epyphysis
When Osteochondrosis happens at the proximal part of the femor it is called
Legg-Calve-Perthers disease
What is the cause of Legg-Calve-Perthers disease
Unknown
Pathogenesis of Legg-Calve-Perthers disease
Avascular necrosis
Age of patients with Legg-Calve-Perthers disease
5-10 years
Which is the leading theory of cause (Legg-Calve-Perthers disease)
Vascular theory
Main blood supply for the femoral epyphysis
Lateral side of epyphysis from the circumflex artery
Stages of Legg-Calve-Perthers disease
Initial necrotic
Fragmentation
Healing reossification
Growing remodeling
What happens to the femoral neck in Legg-Calve-Perthers disease
Becomes shorter and wider
How can we classify Legg-Calve-Perthers disease
Lateral Pillar
A, B, C
Lateral Pillar is based on what features?
Involvement of the lateral epiphysis
Clinincal picture in case of Legg-Calve-Perthers disease
Hip limping
Muscular atrophy
Pain in groin thigh knee
Hip limping can also be called
Trendelenburg sign
Operative methods in case of Legg-Calve-Perthers disease
Proximal femoral Varus osteotomy
Define Congenital Dislocation of the hip
Abnormality of the hip joint where the acetabulom does not fully cover the femoral head
Increased risk for joint relocation
Congenital Dislocation of the hip is more common in male/female
Female (X6)
Congenital Dislocation of the hip- Dislocation reposition maneuver is called
Ortolani’s sign
Congenital Dislocation of the hip- unstable hip test is called
Barlow test
Congenital Dislocation of the hip
Later symptoms
Trendelenburg’s sign
Insufficiency of gluteus medius and minimus
Congenital Dislocation of the hip
Conservative treatment
Closed reduction
Site of involvement
Chondroblastoma
Femur > Prox. tibia > Prox. humerus
Medial collateral ligament of the elbow consists of (3)
Anterior bundle
Posterior bundle
Transverse ligament
Tendinosis in the extensors origin of the elbow is also called
Tennis elbow
Lateral side!
Tendinosis in the flexors origin of the elbow is also called
Golf elbow
Tendinosis=
Angiofibroblastic tendinosis
No inflammatory cells!
Whichone is the more common tendinosis?
Medial
Lateral
Lateral (Tennis elbow)
Lateral tendinosis usually affects which extensor muscle origin
Extensor carpi radialis brevis
