Long-term histological analysis of innervation & macrophage infiltration in a mouse model of intervertebral disc injury‐induced low back pain
Authors: Lee S, Millecamps M, Foster DZ, Stone LS.

Low back pain (LBP) is a leading cause of global disability. Multiple anatomical, cellular and molecular factors implicated in LBP, including degeneration of lumbar intervertebral discs (IVDs). We previously described a mouse model that displays behavioral symptoms of chronic LBP.

Introduction of Disc Material into the Vertebral Canal by Fenestration of Thoracolumbar Discs Following Decompressive Surgery
Authors: Harris G, Freeman P.

OBJECTIVE: Intervertebral disc extrusion is a common disease affecting chondrodystrophic dogs. It has been reported that fenestration of thoracolumbar intervertebral discs reduces recurrence of disc extrusion and is associated with a low complication rate.

Flexed radiographic angles for determination of atlantoaxial instability in dogs
Authors: White DA, Renberg WC, Roush JK, Hallman MR, Mauler DA, Milliken GA.

OBJECTIVE: To determine a flexed position for radiographic diagnosis of atlantoaxial instability (AAI) and to identify radiographic measurement cutoffs to differentiate affected dogs from neurologically healthy toy breeds.

STUDY DESIGN: Retrospective case series and prospective case controls.

Authors: Lee JH, Yoon HY, Kim JH, Han HJ.

CASE DESCRIPTION: 3 toy-breed dogs (a 5-year-old Pomeranian, a 12-year-old Pomeranian, and a 13-year-old Yorkshire Terrier) were evaluated because of a sudden onset of nonambulatory tetraparesis.

Fractures of the Second Cervical Vertebra in 66 Dogs and 3 Cats: A Retrospective Study
Authors: Schmidli FE, Stein VM, Aikawa T, Boudrieau RJ, Jeandel A, Jeffery N, Jurina K, Moissonnier P, Rupp S, Vidondo B, Forterre F.

BACKGROUND: In human medicine, fractures of the second cervical vertebra have been studied elaborately and categorized in detail. This is not the case in veterinary medicine where clinical decisions are often based on old studies focusing on the cervical spine in general.
