The objective of the present study was to evaluate the ability of estrogen to promote induced tibial fracture healing in a rat model. The study was conducted on 14 albino rats divided into two equal groups (seven rats in each group). The first group considered as a control group. The second group was injected estradiol solution 0.1 mg/kg into the fracture gap. The progress of healing in each group was evaluated by clinical, radiography, ultrasonography and pathological examinations. The healing process was observed to be superior in the estrogen group compared to the control one. Estrogen was found to promote healing of injured bone and is suggested to be used in cases of complicated or delayed bone fracture.

This study was conducted to assess the healing of transverse ulna fracture when fixed with external skeletal fixation (ESF) in pigeon. Ulna fracture was created under Isoflurane anesthesia in pigeons. A total of 12 pigeons were used in this study, and they were divided into three equal groups: Group-1, Group-2 and Group-3. The birds of the three groups were sacrificed at 3, 6, and 12 weeks after successful fracture surgery. It was found that bone union occurred between three and six weeks in all groups. Bone alignment, and callus remodeling were evident at 12 weeks (p<0.05) post fracture fixation. There were no radiographic evidence of callus remodeling in any bird at 3 and 6 weeks post-surgery. The radiographic observations of fracture healing in this study have confirmed that ESF fixation is an effective method to stabilize ulna fracture in pigeons and results in faster fracture healing.
