Can high‐resolution peripheral quantitative computed tomography imaging of subchondral and cortical bone predict condylar fracture inThoroughbred racehorses?

Abstract

Increased BV/TV of the distal metacarpus may have some value for identifying horses at risk of any fatal breakdown injury but not metacarpal condylar fractures. Measurement of parasagittal groove subchondral bone thickness is complicated by adjacent palmar osteochondral disease lesions. Thus, high-resolution imaging of the distal metacarpus appears to have limited ability to identify horses at risk of condylar fractures.

Can we use subchondral bone thickness on high‐field magnetic resonance images to identify Thoroughbred racehorses at risk of catastrophic lateral condylar fracture?

“…In contrast to the study by Trope et al [12] who examined the potential predictive value of peripheral quantitative computed tomography, MRI may therefore offer some ability to identify horses at risk of lateral Choosing the optimal cut off obviously has significant implications for the ability of any test to perform in a discriminatory manner.

Can quantitative computed tomography detect bone morphological changes associated with catastrophic proximal sesamoid bone fracture in Thoroughbred racehorses?

“…Nominal logistic regression was used to determine the influence of bone morphology on fracture risk [11]. To avoid oversampling each horse, the average bone morphology parameters were determined in the Fracture Gelding 3 3 3 0 Control Gelding 3 3 22 0 Fracture Mare 3 3 20 1 Control Mare 3 2 61 3 Fracture Mare 3 2 70 8 Control Mare 3 2 67 9 Fracture Gelding 4 2 84 8 Control Gelding 3 2 57 0 Fracture Mare 4 2 138 12 Control Mare 4 3 104 9 Fracture Mare 8 4 194 33 Control Mare 5 2 134 26 Fracture Colt 7 2 253 33 Control Colt 7 2 240 28 Fracture Gelding 7 2 231 34 Control Gelding 10 2 Micro-CT images were acquired of proximal sesamoid bones from animals that sustained a fracture (in both the fractured and contralateral limb) and sex and age matched controls.…”

Surgical repair of propagating condylar fractures of the third metacarpal/metatarsal bones with cortical screws placed in lag fashion in 26 racehorses (2007–2015)

“…Cast was removed within 24 h after recovery in 21 cases (81%). Horses were hospitalised for an average of 6 days after fracture fixation. The mean time between fracture repair and screw removal was 14 weeks [10–36].…”
