Use of «Lit-Ar» Material for the Substitution Long Bone Postosteomyelitic Defects

n 31 patients biodegradable collagen-apatite «Lit-Ar» was used for the substitution of 3-8 cm lone bone defects resulted from osteomyelitic resection. Roentgenologic control followed by computer analysis of roentgenograms was applied to evaluate the processes of material biodeg-radation and bone formation. Good results were achieved in 22 (71%) patients, satisfactory - in 4 (12.9%) and unsatisfactory - in 5 (16,1%) patients. It was shown that the recurrence of purulent-inflammatory process in the implant zone did not require «Lit-Ar» removal. Antibacterial therapy (general and local) was used without repeated surgical intervention and did not cause the rejection of implant. The study allows to conclude that taking into account both medical and economic indices composite material «Lit-Ar» could be used for the treatment of long bone defects
