Fractures around the hip: inducing life-like fractures as a basis for enhanced surgical training.
In this study we investigated if realistic fracture patterns around the hip can be produced on human cadaveric specimens with intact soft tissue envelope. Possible applications of such fractured specimens would be in surgical training. ⋯ A high energetic impulse induced by a custom-made drop-test bench can successfully simulate realistic proximal femur and acetabular fractures in cadaveric specimens with intact soft tissue. Furthermore, axial load using a hammer as well as using a chisel through a direct dorsal approach represent additional methods for fracture induction. These pre-fractured specimens can be utilized in surgical education to provide a realistic teaching experience for specialized trauma education courses.

Comparison of risk for postoperative hyperextension between cruciate retaining and posterior stabilized total knee arthroplasties.
The incidence of postoperative hyperextension and factors affecting hyperextension needs to be investigated separately for cruciate retaining (CR) and posterior stabilized (PS) total knee arthroplasties (TKAs), because the mechanism for preventing hyperextension is different according to the bearing design. The purpose of the study was to compare the incidence of postoperative hyperextension between CR and PS TKAs and analyze the factors affecting the postoperative hyperextension. ⋯ III.

Endoscopic "internal splinting" repair technique for acute Achilles tendon rupture.
Recently, endoscopically assisted Achilles tendon repair techniques have improved to overcome the surgical complications. However, the risk of sural nerve injury and the strength of repair are still the most concerning aspects. ⋯ Level IV, case series.

RSA, TSA and PyC hemi-prostheses: comparing indications and clinical outcomes using a second-generation modular short-stem shoulder prosthesis.
The goal of this study was to provide an insight into the clinical results after modular short-stem shoulder arthroplasty for various indications. ⋯ Using a second-generation short-stem shoulder prostheses, TSA achieves the best clinical improvements overall, especially for OA with a Walch A glenoid. Despite refixation of the subscapularis tendon in all cases, RSA has inferior internal rotation than TSA and PyC, suggesting a mechanical limitation. OA, a Walch B glenoid and arthritis caused by instability seem to be ideal indications when considering PyC.
