LONG-TERM CLINICAL STUDY OF TREATMENT OF ADULT OSTEOMYELITIS WITH OSTEOSET

Abstract

Long-term clinical study to explore the curative effect and mechanism of the treatment of adult chronic osteomyelitis by implant Osteoset T.

The study object were 65 case adult chronic osteomyelitis patient from November 1977 to April 2003 in a University-based hospital. Age ranged from 18 to 69 years old. 40 cases were treated by general debridement (Method I); 25 cases were treated by general debridement and implant Osteoset T in dead space (Methods II). Stage IA(The UTMB Staging System) osteomyelitis 39 cases; The Organism was Staphylococcus Aureus 28 cases. In all cases (group A), 40 cases were treated with Method I (group AI), 25 cases were treated with Method II (group AII). The majority of the patients, 39 resulted as Stage IA (group B); 22 were treated with Method I (group BI) and 17 cases were treated with Method II (groupBII). Finally, 28 patients were chronic Staph Aureus osteomyelitis (Group C); 13 were treated with Method I (group CI) and 15 cases with Method II (group CII); Followed from 36 to 334 months, mean 75.0 months. Then respectively evaluate and analysis analyze the success rate of different method with standard.

The success rate of group BI was 59.09%, group BII was 94.12%, contrast the success rate there was significant difference (p< 0.05). The success rate of group AI was 60.00%, group AII was 80.00%. The success rate of group CI was 46.15%, group CII was 80.00%.

The use of Osteoset T has demostrated better healing rate than left the empty cavity there after debridement and irrigation. Osteoset T can local delivery antibiotic, filler of the dead space, It can be mixed with different antibiotics, reduces the hospitalization time, reduces the number of operation. Unfortunately, Osteoset dos not help with the bone growth.
