The right hips of 69 five-day-old rabbits were dislocated surgically and left to develop in the dislocated position to determine the nature and timing of changes in the hip. Using the left hips as controls, 15 survivors were killed and studied macroscopically and microscopically at two months of age and 14 at four months of age. It was found that articular cartilage of the acetabulum in the dislocated hips showed fibrous degeneration in about 50% of the two-month-old rabbits cases and in all of the four-month-old rabbits. In the dislocated femoral heads the articular cartilage was normal, and only 25% of the four-month-old animals showed fibrous degeneration.
对69只5日龄家兔的右髋进行手术脱位，并任其在脱位状态下发育，以确定髋关节变化的性质和时间。以左髋作为对照，15只存活的家兔在2月龄时处死并进行大体和显微镜检查，14只在4月龄时处死并进行检查。结果发现，在脱位髋关节中，约50%的2月龄家兔髋臼关节软骨出现纤维变性，而在所有4月龄家兔中均出现。在脱位的股骨头中，关节软骨正常，仅25%的4月龄动物出现纤维变性。
