Device for rotational stabilization of bone segments

Abstract: A device for rotational stabilization of bone segments comprising a bone plate (10), a bone lag screw (18), and a locking collar (50). The bone lag screw (18) has a bone-engagement end (20), a distal end, and a keyed cross-sectional profile (32), the bone-engagement end (20) configured for engaging a first bone segment. The bone plate (10) has a flat portion (12) for engaging a second bone segment and a barrel portion (14) having an internal bore for slidably receiving the lag screw (18). The locking collar (50) has a keyed internal profile (21) that mates with the keyed cross- sectional profile (32) of the lag screw (18) to rotationally couple the locking collar (50) and the lag screw (18) when the lag screw (18) is inserted through the locking (collar50) , and an outer surface configured and dimensioned for free rotation, in a first position, within the internal bore (16) of the bone plate barrel portion (14) and frictionally engaging, in a second position, the internal bore (16) of the bone plate barrel portion (14) to resist or prevent rotation of the collar (50) relative to the bone plate (10), and thereby resist or prevent rotation of the lag screw (18) relative to the bone plate (10). The frictional engagement is achieved by a deformation of the distal end (56) of the locking collar (50) within the internal bore (16) of the bone plate (10). This deformation is achieved by the application of force to the collar in the proximal direction.

Needle safety device with antiremoval protection

Abstract: A needle safety device has a collar and a housing pivotally connected thereto. Cooperating locking members are provided at the collar and the respective lower sections of the housing so that, once the housing is pivoted to be in alignment with the collar, the locking members would coactingly mate with each other to thereby retain the housing to the collar. To ensure that the coacting locking members could not be sabotaged by the sidewalls of the housing being deliberately forced away from the collar, barriers in the form of guard flaps or arms are provided at the collar so as to prevent those sections of the sidewall that are susceptible to being forced away from the collar from being exposed. As an added benefit, the guard flaps could be used as an anchor to provide stabilization for the use of a hypodermic needle fitted with the safety needle device of the instant invention during a subcutaneous procedure to a patient.

The management and prevention of rigid cervical collar complications.

Abstract: The rigid cervical collar has been a great addition to the successful management of cervical spine injuries. But the collar has been known to offer a false sense of security in terms of totally preventing additional and further spinal cord compromise and damage. Also, with increased length of collar wear, there is development of skin pressure points and ulcer formation, possible delay in weaning from a ventilator, potential for exposure to transmission of blood-borne diseases. Photographs are used to demonstrate examples of related skin breakdown, show proper collar fit, present the result of ineffective cervical immobilization, and show how to stabilize the head and neck during a collar change. These problem areas are addressed with the dos and don'ts for nursing management.

Expectations and realities of GPS animal location collars: results of three years in the field

Abstract: GPS collars have the potential to automatically collect large numbers of relatively accurate animal relocations. Collar costs, levels of accuracy, and satellite signal reception have been reported by other studies, but there has been little discussion of long-term performance under field conditions. Between March 1996 and April 1999, we placed 11 GPS collars on 23 individual woodland caribou Rangifer tarandus caribou for a total of 26 collar deployments. Reliability was highly variable; some collar deployments operated normally for their expected period of time, other deployments functioned for less than half of their expected lives. Collars attempted 41,822 locations and collected 15,247 3-D and 10,411 2-D locations, for an average acquisition rate of 59%. We recommend that researchers carefully consider project objectives, budget constraints, and available options such as differential correction and remote collar communication, before purchasing GPS collars.
