Flexibility and fatigue evaluation of oblique as compared with anterior lumbar interbody cages with integrated endplate fixation.

Objective: This study was undertaken to quantify the in vitro range of motion (ROM) of oblique as compared with anterior lumbar interbody devices, pullout resistance, and subsidence in fatigue.

Methods: Anterior and oblique cages with integrated plate fixation (IPF) were tested using lumbar motion segments. Flexibility tests were conducted on the intact segments, cage, cage + IPF, and cage + IPF + pedicle screws (6 anterior, 7 oblique).

Canine distemper in endangered Ethiopian wolves.

The Ethiopian wolf (Canis simensis) is the world's rarest canid; ≈500 wolves remain. The largest population is found within the Bale Mountains National Park (BMNP) in southeastern Ethiopia, where conservation efforts have demonstrated the negative effect of rabies virus on wolf populations. We describe previously unreported infections with canine distemper virus (CDV) among these wolves during 2005-2006 and 2010.

Outcome of anterior cervical discectomy and fusion as perceived by patients treated for dominant axial-mechanical cervical spine pain.

Study Design: An extensive outcome questionnaire using a visual analog scale, the North American Spine Society Satisfaction Questionnaire, a Modified Roland and Morris disability index, and a modified Oswestry Disability Index was used to assess the outcome of anterior cervical discectomy and fusion for those with neck pain.

Objective: To document the clinical outcome for 87 patients who underwent anterior cervical discectomy and fusion for the primary indication of neck pain, as assessed after an average follow-up period of 4.4 years.
