Fig. 433.—Case same as figure 432. Separation of the lower femoral epiphysis of the left two knees (see X-ray tracing, Fig. 434). strength of the joint lies in the ligaments and fasciae about the elbow- and hip-joints, it does not depend upon thecontour of the bones for strength. An attempt to overextendand to bend the knee laterally brings very great strain to bearupon the ligaments that are attached to the lower femoralepiphysis. If this strain is ot sufficient force, the epiphysealcartilage gives way, and the epiphysis separates from the shaftof the femur. The common cause of the accident is the catch- SEPARATION OF THE LOWER EPIPHYSIS 311 ing of the leg or thigh in the spokes of a revolving wheel. Theaccident most often occurs to boys about ten years old (see Figs. 432, 433)- The epiphysis usually separates without splintering the diaph-ysis.
