Abstract:
A humero-ulnar synostosis is a bony connection between the humerus and the ulna. This is a very rare finding and it results in a serious disability of the elbow. Usually, a synostosis of the elbow occurs as a congenital anomaly. In this case, a 6-year-old girl was seen with a post-traumatic humero-ulnar synostosis, which has never been reported in the literature before. Surgical resection of the humero-ulnar synostosis was performed. Along with rapid intensive physical therapy, almost full recovery of function was achieved. The short-term result is very satisfactory, but the long-term results and recurrence rate are still unknown.

Development of the Limb Synovial Joints
The mesenchymal stem cells differentiate into chondrocytes that form the hyaline cartilage, and later the cartilaginous model of the bone. This model further transforms into a bone. This process is known as endochondral ossification.
