A comparison between three irrigation methods in the debridement of contaminated bovine cancellous bone and the effect of duration of irrigation on the efficiency of debridement

OBJECTIVES Irrigation and debridement constitute an important part of treatment of open fractures. We investigated the efficiency of different irrigation methods and durations in cleansing contaminated bovine femur cancellous bone samples and the extent of tissue damage associated with irrigation. METHODS A total of 72 samples of 4x4x1 cm size were obtained from fresh frozen bovine distal femoral cancellous bone. The top surface of the samples were sawed to a 2-mm depth to create four squares equal in size. All the samples were contaminated with construction sand using the same method and were then randomized to three irrigation groups (bulb syringe irrigation, high-pressure pulsatile lavage, and low-pressure pulsatile lavage), each consisting of 24 samples. The duration of irrigation was set as 3, 6, or 9 minutes for every eight samples of each group. After the irrigation procedure, the images were transferred to a computer screen with a video-microscope camera and the number of sand particles on the samples were counted and irrigation-related macroscopic bone damage was assessed. RESULTS The lowest number of sand particles was found on the samples irrigated by high-pressure pulsatile lavage (p<0.001). The duration of irrigation did not affect the efficiency of cleansing in all the groups (p>0.05). The least irrigation-related bone damage was observed in samples irrigated by low-pressure pulsatile lavage for 3 minutes (p<0.01). The amount of bone damage was similar in all groups after irrigations beyond 3 minutes (p>0.05). CONCLUSION Our findings showed that the most efficient method of cleansing contaminated bone samples was high-pressure pulsatile lavage and that prolonged irrigations did not enhance the efficiency of the irrigation method; however, high-pressure irrigation of 3 minute duration resulted in the greatest bone damage.

Diabetic foot lesions and clinical experience Objective: Although some diabetic foot undergone amputation because of progressive wound others heal without complication. This study evaluates the risk factors for amputation of diabetic foot. Material and Methods: This study include 104 patients (77 males, 27 females; mean age 62.3 years; range 23 to 90 years) who had diabetic foot ulcers and treated between 2008 and 2011. Data on age and sex, type and time of diabetes, complications and treatment type were recorded. Results: 36.5% of patients had no any antidiabetic medicine. The frequencies of diabetes related complications in descending order were as follows; 44.2% retinopathy, 16.3% polyneuropathy, 11.5% nephropathy, 3.8% Charcot joint. According to Wagner Classification most of the patients (n=100) stages found in two to four. Total 82 patients undergone surgical treatment. Conclusion: We consider that multidisciplinary treatment strategy in which orthoapedic surgeons have an important and special mission decreases amputation rate in diabetic foot.
