| Popis: | Category: Ankle Arthritis; Ankle; Hindfoot Introduction/Purpose: Ankle and hindfoot arthrodesis are common interventions for degenerative and inflammatory foot and ankle conditions. These include, but are not limited to osteoarthritis, inflammatory arthritis, deformity, and instability. While we know the addition of bone graft is critical for successful union, we do not fully understand how graft selection affects union rates. Demineralized bone matrix (DBM) is commonly chosen due to its ease of availability and osteoconductive and osteoinductive properties. In our study, we aim to determine if adding BMAc, and thus osteogenic properties, to a DBM allograft improves union rates following ankle and hindfoot arthrodesis. Methods: After receiving IRB approval from our institution, we collected the records of patients who underwent arthrodesis of the hindfoot (subtalar, calcaneocuboid, talonavicular) or ankle during a 10-year time period. Patients were then divided into two groups: arthrodesis performed with the use of DBM and arthrodesis performed with DMB-BMAc. Cases using other graft options such as bulk allograft, autograft, or bone morphogenic protein (BMP) were excluded. Fusion was determined by standard radiographic and clinical criteria and CT scans were utilized in cases which fusion could not be determined. Patients were followed for a minimum of 6 months. If fusion was not complete at that time clinical and radiographic exams were performed at the 9- and 12-month period. Patients were analyzed for sucussesful arthrodesis. Complications and revisions were recorded and analyzed. Results: A total of 124 patients who met the inclusion criteria were identified. In 49 patients only DBM was utilized, and 75 patients BMC was added to the DBM. At 12 months post operatively the group utilizing only DBM had a union rate of 90% while the union rate of the BMAc/DBM had a union rate of 88% (p=0.985) There was no difference in the rate of complications between the two groups and the groups were matched in terms of age, smoking status, DM, sex and BMI. Additionally, in our cohort there was a trend toward increased non-union and complication rate in smokers, although this did not reach statistical significance. Conclusion: Ankle and hindfoot arthrodesis are a reliable treatment option for patients with specific foot and ankle pathology. Our study reports a fusion rate in line with previous studies. The addition of BMAc from the pelvis, attempting to improve the biology of the fusion site, to DBM does not seem to affect fusion rates. |
