what is the lateral talocalcaneal ligaments attachments?
lateral lateral process to lateral calcaneal process under the calcaneal fibular ligament
How much conjunct rotation occurs at the talocural?
30 degrees
Where is the MTP joint in relation to the web space?
its about 2.5 cm behind the web space
how many bones are in the foot?
26 primary, 2-5 sesmoids
What are the the functional units the foot?
- rear foot
- midfoot
- forefoot
How do you tension cervical ligament and innerossous of the subtalar joint
- inversion
2. eversion
How can the hip effect the medial longitudinal arch?
- weak external rotators lead to pronation
2. weak abductor will cause a valgus knee leading to pronation
Which bone is the key stone to the medial arch
the navicular bone
-the ligamentous structure holds up the arch
What are the attachments of the interosseus muscles of the foot?
- they lay dorsal to the deep transverse ligaments
2. they attach to the plantar ligaments of the first MTP joints
What is unique about the calcaneocuboid joint?
- it has a distinct fibrous capsule
2. the dorsal surface is thickened to form the dorsal calcaneoucuboid ligament
How dynamic stability of the transverse arch created?
- ADM spans the arch
- FL-elevates that anterior part of the calcaneous
- FB- increases height of the lateral arch during eversion
- TP-pulls the calcaneous the opposite direction of the FL
How do the distal and proximal tib fib joint surfaces differ?
- proximal is diarthrodial
2. distal is a syndesmosis
where would you expect tendonitis with a rear foot varus?
ankle supinators due to a increase pronation velocity and greater demand for eccentric control
where id you get a callus formation with rear foot varus?
under the met head because you tend to have a heel whip
What is a hammer toe?
Deformity of the toes with MTP ext or neutral, PIP flexion, DIP extension
