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.

Biomechanics of a cemented short stem: a comparative in vitro study regarding primary stability and maximum fracture load.
In total hip arthroplasty, uncemented short stems have been used more and more frequently in recent years. Especially for short and curved femoral implants, bone-preserving and soft tissue-sparing properties are postulated. However, indication is limited to sufficient bone quality. At present, there are no curved short stems available which are based on cemented fixation. ⋯ Primary stability of the cemented short stem was not negatively influenced compared to the cemented conventional stem and no significant difference in fracture load was observed. However, a clear difference in the fracture pattern has been identified.

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.
