Chapter 102 - Tibial Plateau and Tibial-Fibular Shaft Fractures Flashcards
what injuries are most commonly associated with tibial plateau fractures?
- meniscal injury - 50%
- cruciate or collateral ligament injury - 30%
plateau view xr
10 degree caudal tilt
what structural material has the best outcomes when treating tibial plateau fractures
calcium phosphate cement (lower incidence of articular subsidence compared with autograft)
knee stiffness in tibial plateau fractures is associated with?
high energy injury, use of an external fixator
what percentage of axial loads do the fibular bear?
15%
anterior leg compartment structures
- tibialis anterior
- EHL
- EDL
- Peroneus tertius
- anterior tibial artery
- deep peroneal nerve
lateral compartment of the leg structures
- peroneus longus
- peroneus brevis
- superficial peroneal nerve
superficial posterior compartment of the leg
- gastroc
- soleus
- plantaris
- sural nerve
deep posterior compartment of the leg
- tibialis posterior
- fhl
- flexor digitorum
- popliteus
- posterior tibial artery
- tibial nerve
indications for surgical management of tibial shaft fractures
- > 50% cortical displacement
- > 10degrees of angulation in either plane
- > 1cm shortening
- > 10deg malrotation
benefits of suprapatellar nailing
- less anterior knee pain
- improved sagittal plane alignment
- improved VAS scores
- improved fluoro times
non-reamed tibial nail is associated with what?
higher rate of locking screw breakage
most common proximal malalignment?
procurvatum and valgus
most common distal deformity (if fibular broken at same level)
valgus and procurvatum
most common deformity distally if fibula is intact?
varus
