Patients and Methods
The investigators' institutional review board approved the study. All patients provided written informed constant to participate. A retrospective search of the medical records of all patients presenting to the Ministry of Health's training and research hospital from May 2011 to December 2014 with Sanders type III or IV unilateral calcaneal fractures treated with locking plates and additional bone grafting was done by 2 of us (M.M.S., M.U.).
The inclusion criteria for entry into the study
Results
A total of 91 patients were found who met all the inclusion criteria. Of the 91 patients, 15 were lost to follow-up, leaving a sample of 76 patients (Table 1). Of the 76 patients, 44 (57.9%) had Sanders type III fractures and 32 (42.1%), type IV fractures. All fractures were the result of high-energy trauma; 39 patients (51.3%) had additional associated injuries.
In 60 of the 76 patients (78.9%), the wounds healed primarily. Superficial defects and infections (wound edge necrosis and injuries to
Discussion
In our study, the functional and efficacy outcomes were similar between the 2 groups 1 year after surgery. The high healing potential and cancellous bone structure of the calcaneus could be main factors in the bone healing process.
The median difference between the preoperative and last follow-up measurements was not significant for the GA values in the xenograft group or the allograft group. However, the median difference between the preoperative and last follow-up measurements was significant

Assessing mechanical behavior of ostrich and equine trabecular and cortical bone based on depth sensing indentation measurements
2021, Journal of the Mechanical Behavior of Biomedical MaterialsCitation Excerpt :Moreover, It is observed that the hardness and elastic modulus of the trabecular ostrich is very similar to the trabecular part of human bone (Pawlikowski et al., 2017). Therefore we can conclude that ostrich bone could be a candidate to be used as human body implant, after biotechnological process, just as other researchers have done with the equine bone (Sonmez et al., 2017). By comparing the two characteristic load-penetration depth curves of equine and ostrich trabecular bone (Fig. 11), the elastoplastic transition is clearly displayed by a sudden penetration called ‘‘pop-in’‘, which is related to the transition from the elastic to the elastic/plastic regimes, associated with the beginning of plastic deformation due to nucleation of dislocations.
