Introduction: THR is one of the commonly performed adult arthroplasties in world. Over past 6 decades, Charnley low friction arthroplasty has evolved design and concept. One among those recent advances use 3D printing technology arthroplasties. Purpose this article to discuss share details a hip case where customized printed acetabulum component was used. Case: A 3 year postop fracture fixation...

OBJECTIVES The current experiments had three aims (i) to determine whether the absence of the periodontal ligament (PDL) may alter features of the healing of an extraction socket, (ii) to examine if there were differences in the proportion of different tissues in resolved extraction sockets and surgically produced defects after 3 months of healing, (iii) to study the influence of different biom...

For the treatment of bone defect autogenous bone is most desirable, but there are several drawbacks and risks involved in using autogenic bone such as limited harvest due to insufficient donors, post-operative pain, increased blood loss, secondary surgical wounds and risk of thrombosis [3-5]. Allograft bone could overcome the above limitations, but it endures the risk of transmission of infecti...

Introduction: Congenital vomer agenesis is an extremely rare condition in which the vomer bone does not fully develop, which can lead to septal perforation. Case Report: We report two cases with a defect in the vomer bone in the posteroinferior portion of the septum, found accidentally while performing a pre-operative CT scan for nasal obstruction evaluation. They were diagnosed with congenital...

traumatic injuries in the primary dentition pose major challenges for management. this emergency treatment requires proper planning so as to achieve favorable results. trauma causing severe dentoalveolar injuries, especially in children, needs an interdisciplinary approach so as to retain normal functional anatomy for that age. this article describes a clinical innovative technique, which utili...

Bone loss management is an important consideration in revision total knee arthroplasty (TKA) (Figures 1-3). Large structural allograft use is an option that offers two significant advantages. First, allograft bone is readily available.1 As a graft material, this bone is sterilized and preserved by freezing. Second, allograft bone provides support for the adjacent implant by maintaining its stru...

Postpartum aortic intramural hematoma (IMH) is a rare but potentially lethal condition. We report a case of aortic IMH with massive hemothorax in a postpartum woman. The patient was a 31-year-old woman who had delivered twins by cesarean section. Two days after delivery, she complained of sudden-onset dyspnea. Chest computed tomography revealed a massive left hemothorax. Exploratory thoracotomy...

A bone scaffold material (nano-HA/ collagen/PLA composite) was developed by biomimetic synthesis. It shows some features of natural bone both in main composition and hierarchical microstructure. Nano-hydroxyapatite and collagen assembled into mineralized fibril. The three-dimensional porous scaffold materials mimic the microstructure of cancellous bone. Cell culture and animal model tests showe...

One advantage of using cartilage to replace/repair bone is that the implant disappears as bone is formed by endochondral ossification. Previously, we showed that cartilage spheroids, grown in a rotating bioreactor (Synthecon, Inc.) and implanted into a 2 mm skull defect, contributed to healing of the defect. Skulls with or without implants were subjected to microCT scans. Mineralized regions fr...
