Pedicled vascularized bone grafts compared with xenografts in the treatment of scaphoid nonunion.
Int Orthop
April 2021
Clinical Center of Serbia, Orthopedic and Traumatology University Clinic, Belgrade, Serbia.
Introduction: Fractures of the scaphoid account for 60-70% of all wrist bone fractures. The results of treatment in terms of bone healing vary depending on the type and location of the fracture, the time elapsed since the injury, the type of surgical treatment. Nonunion occurs in 5-15% of the cases on average.

Department of Orthopaedics, Chinese PLA General Hospital, No. 28 Fuxing Road, Beijing 100853, China. Electronic address:
Objectives: To evaluate a new surgical technique concerning titanium cage packing with xenograft demineralized bone matrix bovine augmentation in the management of subchondral bone defects associated with tibial plateau fractures.
Methods: All patients underwent plate fixation augmentation using titanium cage packing with xenograft, with the help of digital medical software of Mimics and 3-matic preoperatively. Duration of the surgical procedure, intraoperative bleeding volume, bone union time, quality of reduction and alignment, fracture healing, complications, and functional outcomes based on Oxford knee outcome score were recorded.
Purpose: To compare the clinical outcome of immediately loaded cross-arch maxillary prostheses supported by zygomatic implants vs conventional implants placed in augmented bone.
Materials And Methods: A total of 71 edentulous patients with severely atrophic maxillas, who did not have sufficient bone volume to place dental implants or when it was possible to place only two implants in the front area (minimal diameter 3.5 mm and length of 8 mm) and less than 4.
Safety and performance of a novel collagenated xenogeneic bone block for lateral alveolar crest augmentation for staged implant placement.
Clin Oral Implants Res
January 2018
ETEP Research Group, Faculty of Odontology, University Complutense of Madrid, Madrid, Spain.
Objectives: To evaluate the performance and safety of placing a collagenated xenogeneic bone block (CXBB) graft for the lateral bone augmentation of the alveolar crest prior to implant placement.
Material & Methods: In patients with single or multiple tooth gaps and a severe horizontal collapse of the alveolar ridge, a ridge augmentation procedure was performed using CXBB fixated with osteosynthesis screws to the atrophic bone crest and complemented with deproteinized bovine bone mineral particles (DBBM) and a native bilayer collagen membrane (NBCM). Patients were examined with CBCT prior to and 24 weeks after the augmentation.
Allografts versus Equine Xenografts in Calcaneal Fracture Repair.
J Foot Ankle Surg
March 2018
Associate Professor, Department of Orthopaedics, Hamidiye Sisli Etfal Training and Research Hospital, Istanbul, Turkey.
Displaced intra-articular calcaneal fractures are difficult to treat. We determined the functional results and complications of using allografts or equine xenografts in treating these fractures. We reviewed patients seen at our center from May 2011 to December 2014 with Sanders type III or IV unilateral calcaneal fractures treated with locking plates and an additional bone allograft or equine xenograft.
