Background. Delayed union and nonunion are common complications in atypical femoral fractures (AFFs) despite having good\nfracture fixation. Demineralized bone matrix (DBM) is a successfully proven method for enhancing fracture healing of the long\nbone fracture and nonunion and should be used in AFFs. This study aimed to compare the outcome after subtrochanteric AFFs\n(ST-AFFs) fixation with and without DBM. Materials and Methods. A prospective study was conducted on 9 ST-AFFs patients\nusing DBM (DBM group) during 2013-2014 and compared with a retrospective consecutive case series of ST-AFFs patients treated\nwithout DBM (2010ââ?¬â??2012) (NDBM group, 9 patients). All patients were treated with the same standard guideline and followed up\nuntil fractures completely united. Postoperative outcomes were then compared. Results. DBM group showed a significant shorter\nhealing time than NDBM group (28.1 Ã?± 14.4 versus 57.9 Ã?± 36.8 weeks,
