From each talus, 1 histopathology slide clearly depicting the central part of the osteochondral defect was selected for analysis.
The sites of the lesions included skull bones (9), humerus (1), femur (8), tibia (2), fibula (3), talus (1), mandible (1), and maxilla (1).

Cells derived from autologous bone marrow aspirates from the iliac crest have been used for treatment of focal, traumatic chondral and osteochondral defects of the femoral condyle [ 81– 87], femoral trochlea [ 84, 88, 89], talus [ 80, 90, 91], tibial plateau [ 89], and patella [ 84, 88, 89].
The mechanical axis of the tibia was a line joining the midpoint of the tibia at the joint line and the center of the talus [ 12, 15, 16, 18, 21, 25, 27, 32].
The diagnoses were malleolar fractures (N = 18, from which 4 were bi-malleolar and 2 tri-malleolar), mid- and hind-foot fractures (N = 11, 4 calcaneum fractures, 2 talus fractures, 1 cuboid fracture, 1 Chopart's dislocation, 3 Lisfranc dislocations), tibial pilon and fibular fractures (N = 7), and metatarsal fractures (N = 4).
Complex hindfoot anatomy and the associated biomechanics pose a challenge to the surgical treatment of displaced intra-articular calcaneal fractures because the calcaneus is continuously subjected to compressive forces with the articular facets participating in both Chopart's joint of the midfoot and in the subtalar joint with the talus [1, 2, 3, 7].
These rare ossicles are all located adjacent to the dorsal talus [4, 19, 20].
Cartilage marrow stimulation procedures (microfracture), autografts, and allografts may be used to attempt repair of isolated cartilage defects of the tibial plafond or the talus, and block allografts may be used to replace a larger portion of talus [5, 23].
They are best seen on lateral radiographs of the foot and ankle and may be round, oval or triangular and may have a synchondrosis with the posterolateral talus [10, 11].
These range from complex and invasive procedures such as the Blair fusion, [5] which requires an intact head and neck of the talus; prosthetic replacement of the talus; [6] use of block autografts [7] or allografts [8] to less invasive techniques.
