“…If we speculated all these 16 fractures healed, the study nonunion rate would decrease to 14 of 86 (16%). Although some authors have reported a 100% union rate in small series [6,16,31,34,35], most larger series have found a substantial rate of healing difficulties [6,20,[27][28][29]32]. When nonunion, delayed union, the need for secondary surgery, and hardware failure are considered, the rate of healing difficulties reported in the literature is comparable to the rate in our study (Table 6) [6, 7, 11, 14-16, 20, 27-29, 31, 32, 34, 35].…”

Background Several mechanical studies suggest locking plate constructs may inhibit callus necessary for healing of distal femur fractures. However, the rate of nonunion and factors associated with nonunion are not well established. Questions/purposes We (1) determined the healing rate of distal femur fractures treated with locking plates, (2) assessed the effect of patient injury and treatment variables on fracture healing, and (3) compared callus formation in fractures that healed with those that did not heal. Patients and MethodsWe retrospectively reviewed 82 patients treated with 86 distal femur fractures using lateral locking plates. We reviewed all charts and radiographs to determine patient and treatment variables and then determined the effects of these variables on healing. We quantitatively measured callus at 6, 12, and 24 weeks.The minimum time for telephone interviews and SF-36v2 TM scores was 1 year (mean, 4.2 years; range, 1-7.2 years). Results Fourteen fractures (20%) failed to unite. Demographics and comorbidities were similar in patients who achieved healing compared with those who had nonunions. There were more empty holes in the plate adjacent to fractures that healed; comminuted fractures failed to heal more frequently than less comminuted fractures. Less callus formed in fractures with nonunions and in patients treated with stainless steel plates compared with titanium plates. Complications occurred in 28 of 70 fractures (40%), 19 of which had additional surgery. Conclusions We found a high rate of nonunion in distal femur fractures treated with locking plates. Nonunion presented late without hardware failure and with limited callus formation suggesting callus inhibition rather than hardware failure is the primary problem. Mechanical factors may play a role in the high rate of nonunion. Level of Evidence Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence.

“…Reported clinical nonunion rates after treatment of distal femur fractures with locking plates vary between 0% and 10% [6,7,11,16,20,27,29]. Difficulties with fracture healing in the distal femur may present clinically as delayed union, hardware failure, loss of alignment, or an established nonunion.…”

“…Recent clinical studies substantiate the concern that the inherently high stiffness of locked-plate constructs suppresses callus formation, contributing to a nonunion rate of up to 19% seen with periarticular locking plates 16,17 . Deficient healing may also contribute to late hardware failures seen with locking plates [18][19][20] since, in the absence of osseous union, constructs remain load-bearing and eventually fail by hardware fatigue or loss of fixation.…”
