Absence of the right wing of the ilium generated a compensatory scoliosis in rhesus monkey in captivity: diagnostic imaging and its alteration on the SEPNT.

Background: Congenital scoliosis (CS) is defined as lateral curvatures of the spine provoked by the anomalous development of the vertebral bodies. It is associated with neuromuscular anomalies, which can be genetic, caused by the compensation of discrepancies in the length of the extremities or intrarachidian anomalies.

Methods: This study was carried out in 2-year-old female, showed alterations in the gait, mainly in the hind limbs, a clumsy gait and a slight claudication in the right hindlimb.

Preliminary studies of neurosensory and cardiopulmonary health compromise in captive- bred Rhesus macaques (Macaca mulatta) suffering scoliosis.

Background: It has been widely documented that quadrupedal animals rarely display natural spontaneous scoliotic rachis deviations of the spinal column. The objective was to determine spinal deformities developed by geriatric monkeys of the Macaca mulatta species, by radiographical and tomographical studies of the vertebral column correlating morphological changes with altered physiological parameters and electrical neurosensorial conductivity of somatosensory-evoked potentials (SEPs).

Materials And Methods: A cohort of six geriatric monkeys was used: three non-scoliotic subjects and three monkeys with naturally acquired true scoliosis.

Characterization of spontaneous subclavian steal phenomenon in a female rhesus macaque (Macaca mulatta).

In subclavian steal phenomenon (SSP), the subclavian artery develops a stenoocclusive disease proximal to the origin of the vertebral artery, leading to pronounced hemodynamic changes such as arterial flow reversal. Although SSP is a common echographic finding in humans, the phenomenon occurs only rarely in animals; consequently its physiologic features have not been reported previously. Here we describe the clinical and morphologic features of a spontaneous left SSP that was an incidental finding in an 18-y-old female rhesus macaque (Macaca mulatta).

Radiographic incidence of spinal osteopathologies in captive rhesus monkeys (Macaca mulatta).

Degenerative spinal disease is a leading cause of chronic disability both in humans and animals. Although widely seen as a normal occurrence of aging, degenerative spinal disease can be caused by various genetic, iatrogenic, inflammatory, and congenital factors. The objective of this study was to characterize the degenerative spine-related diseases and the age at onset in a random subpopulation of 20 captive rhesus monkeys (Macaca mulatta; male, 13; female, 7; age: range, 4 to 27 y; median, 18.
