Fracture of the tibial tuberosity is an uncommon injury and rarely occurs after closure of the proximal tibial epiphysis. Three cases of tibial tuberosity fracture over a period of 11 years were treated by open reduction, internal fixation, and immobilization for 6 weeks in plaster of Paris (1970-1980). The postoperative follow-up times were 5, 6, and 7 years. ⋯ Two patients had secondary posttraumatic patella infera without any symptoms. All patients returned to normal activity. The results demonstrated that this injury in the adolescent knee heals without deformity of functional loss when adequate reduction and fixation of the fracture fragments have been achieved.

Mechanical effects of intramedullary reaming on osteotomy healing in rats.
The effect of intramedullary reaming on the healing of stable femoral osteotomies was studied. In one group of rats reaming of the medullary cavity was performed, and a partial, transverse osteotomy was made at the mid-shaft. ⋯ There were no significant differences in these biomechanical parameters between the two groups during the experimental period. The results indicate that reaming of the medullary cavity of diaphyseal bone does not significantly impair the healing of fractures that are rigidly fixated.
