Abstract
PDF - We treated 3 cases of fracture and 1 case of avascular necrosis of femoral head using autologous cultured osteoblasts injection. The stromal cells from the bone marrow were cultured to differentiate to osteoblasts for 4 weeks. The fracture sites of each patients were right ulnar shaft, left radial shaft, and left 5th metatarsal base. All of the fractures showed callus formations after 1 week of osteoblasts injection to the fracture site. After 4 weeks, callus formations were progressed. Avascular necrosis of femoral head was bilateral and both were Ficat stage II. Core decompression and allograft impaction were performed to the left, and core decompression and autologous cultured osteoblasts injection percutaneously after 4 weeks of the decompression operation were done to the right femoral head. CT images of 1 year from the operations showed trabecular bone formation and well maintained femoral head contour of the right femur, but resorption of the grafted bone for the left.

- PURPOSE
Untreated meniscus injuries accompanied with fractures of lateral tibial condyle may cause prolonged pain and post-traumatic arthritis. Lateral displacement of fractured fragment of lateral tibial condyle was found to be related to the incidence of lateral meniscus tear. We established the risk groups for lateral meniscus injuries on the basis of the degree of the lateral displacement of lateral tibial condyle.
MATERIALS and METHODS
Risk groups for lateral meniscus injury in fractures of lateral tibial condyle were evaluated in 39 knees, retrospectively, using plain roentgenograms and arthroscopic findings. On the knee anteroposterior radiography, displacement of lateral tibia condyle were classified into three groups according to the probability of lateral meniscus INJURY: high risk group for above 8mm of lateral displacement; moderate risk group for 4-8mm; low risk group for less than 4mm.
RESULTS
High risk group has ten meniscus injuries among 13 knees(76.9%) and moderate risk group had the seven meniscus injuries of 18 knees(38.9%). Low risk group of eight knees had no meniscus injury(0%). These different incidences among groups were statistically significant(p<0.05).
CONCLUSIONS
The authors suggest that the incidence of lateral meniscus injury was related to the degree of lateral displacement of lateral tibial condyle, and our definition of risk groups are useful for prediction of lateral meniscus injury in fracture of lateral tibial condyle.
