– Discussion: – comprise 12-15% of clavicular frx & are subclassified according to location of CC ligaments relative to fracture fragments; – distal clavicle fractures may have a high incidence of non union but most of these are asymptomatic, and of these only a small number will be severe enough to require surgery; – … Read more
– Discussion: – extra-articular arthrodesis which is useful in blocking subtalar motion in those patients who have no gross skeletal deformities but have instability of the hindfoot; – this arthrodesis is particularlly applicable in children, since there is little interference with future growth of the foot; – spastic pes … Read more
