Device-related litigation & clinical engineering.

The investigation of patient-related incidents often must include consideration of the role of the associated medical devices. In addition to being good practice from quality review perspectives, federally mandated MDR requirements generally need to include clinical engineering input. Medical devices also play a significant role in patient litigation aimed at medical providers, hospitals and device manufacturers. Clinical engineering has an important role to play in supporting and tracking litigation as it relates to medical equipment. This role requires an understanding of the litigation process and active participation as a claim progresses. It also should include careful evaluation of the assertions and defenses raised by the various parties both during and at the conclusion of litigation.

Holding power of threaded external skeletal fixation pins in the near and far cortices of cadaveric canine tibiae.

We compared the pin-bone interfaces at the near and far cortical penetration sites of positive-profile end-threaded external fixation pins in cadaveric canine tibiae. The holding power of the pins in each cortical surface was independently measured in 21 pin-bone sections. Scanning electron microscopy (SEM) was used to compare subjectively the microstructural appearance of the pin-bone interfaces at the near and far cortical penetration sites in eight pin-bone sections. The far cortical penetration site provided greater holding power than did the near cortical site. SEM evaluation suggested more bony microfractures and debris with less pin-bone SEM evaluation suggested more bony microfractures and debris with less pin-bone interlock in the near cortical penetration sites than in the corresponding far cortical penetration sites. This study showed that after low-speed power insertion of positive-profile end-threaded pins in canine cadaveric tibiae, the near cortical penetration site contributes approximately 25% less to the overall holding power of the pin than does the far cortical penetration site.
