Osseointegrability of 3D-printed porous titanium alloy implant on tibial shaft bone defect in rabbit model.

Previous studies have demonstrated the ability of osseointegration of porous titanium implants in cancellous bone. Our study was designed to (i) investigate the ability of bone ingrowth into 3D-printed porous titanium alloy implant on the cortical bone of rabbits using CT-scan and histology, and (ii) to identify the consistency of the radiology information between clinical Cone Beam Computed Tomography (CBCT) and Micro Computed Tomography (μCT) in the evaluation of bone ingrowth. The porous titanium alloy implants were 3D-printed employing the Electron Beam Melting (EBM) technology with an intended pore size of 600 μm and porosity of approximately 50 percent.

Locked thumb metacarpophalangeal joint due to sesamoid bone entrapment: A case report and review of literature.

Locked thumb metacarpophalangeal (MCP) joint has been known as a relatively rare condition. We present a case of a 25-year-old male presented with a traumatic locked thumb MCP joint of the right hand. Clinical presentation showed the joint was in a hyperextention position and resistant to active flexion and extension.

The use of a 3D-printed personalised drill guide for posterior column lag screw fixation in displaced transverse acetabular fracture: A case report.

Introduction And Importance: Anterior column plate combined with posterior column screws have been effectively used for treatment of displaced transverse acetabular fractures. This article presents the use of 3D-printed technology for customising a guide template to appropriately place posterior column screw.

Case Presentation: A 50-year-old female suffered displaced juxtatectal fracture of the right acetabulum.
