Document Summary

Has corresponding condyles to femoral (cid:272)o(cid:374)dyles (cid:271)ut are flatte(cid:374)ed = (cid:858)plateaus(cid:859) Has anterior, medial and lateral sharp margins so that cross-section is triangular. Distal end medial malleolus and fibular notch (articular surface with fibula) Fibula - does(cid:374)(cid:859)t arti(cid:272)ulate (cid:449)ith fe(cid:373)ur ((cid:374)ot (cid:449)eight-bearing) so can be used as graft. Posterior surface has two articular facets medial (bigger) and lateral (deeper) Most tibial fractures occur at the junction of the middle and distal thirds (boot-top fracture in skiers) where the bone is narrowest and has poor blood supply. Fracture of the tibia is commonly associated with fibula fracture, common fibular nerve endangered proximally. Osgood schlatter syndrome = inflammation of the patellar ligament at the tibial tuberosity (epiphyseal growth plate where secondary ossification occurs at around 12 years of age) repeated running/jumping actions cause patellar ligament to pull on the tibial tuberosity. Intermuscular septa form 3 compartments: anterior (dorsi-flexors and invertors, lateral (evertors, posterior (plantar-flexors and invertors) superficial and deep.
