Lower Limb Flashcards
Longest and strongest bone of the body
Femur
Femoral head is covered with cartilage apart from a central pit called _______, where the ligamentum teres is attached
Fovea
Blood supply of femoral head
Vessels in the cancellous bone from the shaft
Vessels in the capsule of the hip joint, which reach head in synovial folds along the neck
Negligible supply via the fovea from vessels in the ligamentum teres
Ridge posterior to the shaft of femur
Linea aspera
Line between greater and lesser trochanter located anteriorly
Intertrochanteric line
Posterior line between greater and lesser trochanter
Intertrochanteric crest
Lower end of femur is expanded into two prominent condyles united anteriorly as the patellar surface by separated posteriorly by
Deep intercondylar notch
Above the articular surface on the lateral side of femur is a small depression that marks the origin of what muscle
Popliteus muscle
Line along the inferior margin of the neck of the femur forms a continuous arc with the superior and medial margin of the obturator foramen of the pelvis is called ______
This line is disrupted in congenital dislocation of hip
Shenton’s line
Sesamoid bone called _______ is frequently seen in lateral head of gastrocnemius muscle.
On radiographs, this is projected on the posterior aspect of the lateral femoral condyle
Fabella
What specific type of femoral neck fracture disrupts blood supply in the head of femur which leads to ischemic necrosis
Subcapital fracture
Sesamoid bone in the quadriceps tendon that continuous at its apex as the ligamentum patellae
Patella
Wiberg type of patella in which the medial and lateral articular facets are equal in size and dimension
Type 1
Type of patella in which the lateral facet is slightly larger than the medial facet
Type 2
Type of patella in which lateral facet is dominant and medial facet is atretic and redundant
Type 3
Patellofemoral alignment is routinely achieved using what position
Skyline position
Patellofemoral tracking is best achieved in this view, in weightbearing and in varying degrees of flexion and extension
Merchant view
Prominent oblique ridge in the posterior surface of the tibial shaft
Soleal line
Mainly a site of origin of muscles in the leg and has no weightbearing function
Fibula
Insertion of biceps femoris
Head of fibula with styloid process
Calcaneofibular ligament is attached to its tip
Lateral malleolus
Fibula is proportionately thicker in adults or children?
Children
