Abstract

Objective: to evaluate the results of (Modification of Russe method) in treatment of nonunion fracture scaphoid bone by bone graft with external splintage (plaster of paris cast (pop ).Methods:Prospective study done on 26 patients (24 male, 2 female), age range between 25-42 years (mean age 34 years), fracture site at middle 1/3 with minimal displacements with no carpal bone or radial bone injury, technique of Matte- Russe method (explore the bone through volar approach using bone graft from iliac crest (cortico-cancellous peg plus cancellus bone) with thumb spica for 90 days with period of follow up 12-18 months.Results: out of 26 patients treated by this method , 23 patients (88.5%) union was achieved radiologically by the end of 3rd month &progressed over the next 3 months, range of motion of the wrist & power of grip increased gradually became almost comparable to the normal side by the end of sixth month , 5-7 degrees loss of dorsiflexion was residual in 6 patients . Three patients (11.5%) did not show union radiolgically after sixth postoperative month, their local symptoms were better than before surgery ,they were not keen to have another operation .No complications were noticed, wound healed well ,patient tolerance was goodConclusion: the use of cancellous bone graft with plaster of paris (p.o.p.) splint is less demanding surgically& less coasty and resulted in good results(88.5% healed well ).we recommend this treatment as a method for treating nonunion of carpal scaphoid bone .Key wards: nonunion, scaphoid , bone graft , plaster of paris

Abstract

Background: Augmentation of the craniomaxillofacial region is required for many aesthetic and reconstructiveprocedures. Many bone grafts substitutes have been developed .These products differ in their osteoconductive andosteoinductive properties .The use of bone graft substitutes offers the ability to lessen the possible morbidity of theharvest site inautograft. Aragonitic calcium carbonate has proved to have biocompatible properties as bone graftsubstitute. This study aimed to evaluate the histopathological effects of aragonitic calcium carbonate inexperimentally induced bone defect in rabbit's mandible.Material & method: Twenty five adult male healthy rabbits were used in current study. Two holes were prepared inthe rabbit's mandible, first hole remain empty as control, the second filled with aragonitic calcium carbonate.Samples were taken after 2, 6,8,12 and 24 weeks. Histopathological evaluation include; examination of new boneformation and inflammatory response, in both control and experimental groups.Results: At 2 weeks, there was no new bone formation in both defects with moderate amount of inflammation .At6,12 and 24 weeks the amount of new bone formation in implant group was more than that formed in control group( statistically highly significant correlation, p<0.01). At 8 weeks, less bone amount in implant group .There weremarked degradation of implant particles at 6 weeks.Conclusions: ACC is suitable bone graft substitute and induce new bone formation by acting as bioactive,osteoconductive bone graft when come in contact with bone.

Abstract

Background: In Maxillofacial surgeries, iliac bone graft has traditionally been harvested to provide osteoconductive,osteoinductive and osteogenic components to initiate bony formation. There are multiple types of procedures forharvesting iliac bone graft, either by surgical exposure procedure for procurement bone graft bicortical, unicortical,tricortical or by using Fritsch bone harvesting (trephine) system or by Spine-Tech grinding harvester technique. Thisstudy compares procedures for harvesting iliac bone graft by using sub-crestal window technique procedure andtrap-door iliac crest bone graft procedure for different purposes like alveolar cleft, bone resection due to tumor,reconstruction of avulsed facial bone due to trauma by bullet injury or RTA, confirming that donor site morbidity ofthe sub-crestal window technique is more significant than trap-door technique.Patients and methods: In this study (40 patients / 22♂:18♀) underwent harvesting of iliac bone graft with age range(3.5-65 years) in Al-Kadhmyea Teaching Hospital (2009-2012) for different purposes like alveolar cleft, reconstructionof mandible after tumor resection and reconstruction of maxillofacial defects due to massive blast or bullet injury.Results and Conclusions: The results indicate that major complications from ICBG harvest are uncommon, but minorcomplications are common. The findings suggest that donor site morbidity of the sub-crestal window technique issignificantly less than trapdoor technique. Making the sub-crestal window technique is the method of choice forharvesting large amounts of bone graft
