Demineralized Bone Matrix Add-On for Acceleration of Bone Healing in Atypical Subtrochanteric Femoral Fracture: A Consecutive Case-Control Study

Figure 1

Radiographs from case examples with atypical subtrochanteric femoral fracture (ST-AFF) treated without using demineralized bone matrix (NDBM group). Preoperative (a) and immediate postoperative (b) radiographs showed ST-AFF treated with cephalomedullary nail. Follow-up radiographs after 2 months (c), 4 months (d), and 6 months (e) showed very minimal callus formation. However, the fracture still had healing progression after 8 months (f) and finally completely united after 14 months postoperatively (g).
