A template for locating a proper place for inserting a needle. The template has two reference indicators that are placed on a persons body and an elongated body, with incremental markings on each side of the elongated body, that moves relative to the two reference indicators. The incremental markings on each side of the elongated body can be scaled differently. One reference indicator is placed over the clavicle and the other is placed over the nipple on the same lateral side. The elongated body is moved until the reference indicators are each lined up with equivalent incremental markings on each half of the elongated body. When the reference indicators are lined up with matching incremental markings, a fixed target, positioned between the two sets of incremental markings, will indicate a proper location for inserting a pneumothorax relief needle.

A container having a base and a cap is disclosed herein for protecting needles and/or catheters during transport. The base has a cavity for storing the needle and/or catheter and a flange region for securing the needle and/or catheter within the base. The cap can be releasably coupled to the base and provide a seal to protect the needle and/or catheter from contamination. Semi-permeable plugs can be disposed on the ends of the base and cap to enable gas sterilization of the container and the needle and/or catheter contained inside.

A durable and reliable illuminating scissor is disclosed herein having a cutting shear and a light source for illuminating the cutting area. The light source can be connected to a part of the cutting shear and can have an internal power source and light bulb. The light source can shine a visible, or other type of light, toward the cutting area to increase visibility for the user.

Background: Infection is a major clinical complication of orthopaedic implants and prosthetic devices, and patients with traumatic open fractures have a high risk of infection that may exceed 30%. Surgical trauma, burns, and major injuries such as traumatic open fractures induce immunosuppression, decrease resistance to infection, and decrease production of T helper type 1 (Th1) cytokines. Questions/hypotheses: Exogenous interleukin-12 p70 (IL-12p70 or IL-12), a natural cytokine that plays a central role in Th1 response and bridges innate and adaptive immunities, will reduce open fracture-associated infection. Method of Study: We propose using exogenous IL-12 nanocoating to restore or enhance the bodys natural defense system to combat pathogens. Rats will have a femur fractured, inoculated with Staphylococcus aureus or injected with phosphate buffered saline, left open for 1 hour, and then fixed with an intramedullary Kirschner wire with or without IL-12 nanocoating. Animals will be euthanized at postoperative Day 21; samples of blood, soft tissue, bone, and draining lymph nodes will be collected. Infection, bone healing, and local and systemic responses will be determined. Significance: IL-12 nanocoating is a promising prophylactic means to modulate the host immune response to help prevent open fracture-associated infections and to avoid the problem of antibiotic resistance. © 2010 The Association of Bone and Joint Surgeons®.

Heterotopic ossification (HO) refers to the formation of mature lamellar bone in nonosseous tissue. In the setting of high-energy wartime extremity wounds, HO is expected to complicate up to 64% of patients, has a predilection for the residual limbs of amputees, and remains a significant source of disability. Although the inciting events and the definitive cell(s) of origin continue to remain elusive, animal models and human histology samples suggest that HO formation follows a predictable sequence of events culminating in endochondral ossification. Primary prophylaxis is not medically or logistically practical in most cases because patients have generally sustained massive wounds and are undergoing serial debridements during an intercontinental aeromedical evacuation. Surgical excision of symptomatic lesions is warranted only after an appropriate trial of conservative measures and is associated with low recurrence rates in appropriately selected patients. Future research regarding prognostication and defining the early molecular biology of ectopic bone may permit individualized prophylaxis and development of novel targeted therapies.
