Answer

Fractures can occur in patients with type II or III SMA, and congenital fractures may be seen in type I SMA. [49]  They occur at an earlier age in type II SMA than in type III SMA. Supracondylar femur and ankle fractures are common in type II SMA, whereas in type III SMA, upper-extremity fractures are common. [50]  Nonoperative treatment is preferred for nonambulatory patients. For ambulatory patients, osteosynthesis is considered in order to maintain walking/standing ability.
