Security of 3D-printed polylactide acid piece sterilization in the operating room: a sterility test.
3D-printing technology has become very popular the last 10 years, and their advantages have been widely proved. However, its safety in the operating room after sterilization has not been evaluated. Thus, the use of 3D printing is still questioned. The aim of this work is to evaluate the security of polylactic acid (PLA) to print surgical models after its sterilization. ⋯ This is the first 3D-printing protocol described to print and sterilize 3D biomodels using an autoclave showing its biological safety and its mechanical resistance.

Intraoperative torsion control using the cortical step sign and diameter difference in tibial mid-shaft fractures.
Intramedullar nailing of tibial mid-shaft fractures is a common surgical treatment. Fracture reduction, however, remains challenging and maltorsion is a common discrepancy which aggravates functional impairment of gait and stability. The use of radiographic tools such as the cortical step sign (CSS) and the diameter difference sign (DDS) could improve fracture reduction. Therefore, the validity of the CSS and DDS was analyzed to facilitate detection of maltorsion in tibial mid-shaft fractures. ⋯ The present study has shown, that maltorsion can be reliably assessed by the CSS and DDS during fluoroscopy. Thus, torsional discrepancies in tibial mid-shaft fractures can be most reliably assessed in the lateral plane by analysis of the LCT and TD.

To describe the epidemiology of Pipkin fractures including detailed fracture classification and outcome for joint preservation and death. ⋯ Three of four fractures occurred in males and more than half of the fractures were due to high energetic injuries. Half of the patients received internal fixation (predominantly younger patients) and 28% were treated with primary arthroplasty (predominantly older patients). The revision rate was low, and after secondary treatment with arthroplasty two thirds of the patients still had a preserved joint.
