Objective To characterize and contrast data from Thoroughbreds that incurred a fatal musculoskeletal injury ( fmi ; resulting in death or euthanasia) during racing training all California race entrants 9-month period 1991. Design Case-control study. Animals at race-meet January through June October December Procedure Age sex were compared with χ 2 Fisher's exact tests among horses fatally injured while training. A log-linear model was fit to assess the relationship between age of entrants....
Abstract The purpose of this study was to investigate the relationships between data obtained from quantitative computed tomography and mechanical properties in equine metacarpus, as measured vitro bone specimens. Three hundred fifty‐five specimens metacarpi 10 horses were machined into right cylinders aligned with long axis bone. A tomographic scan specimens, along a Cann‐Genant K 2 HPO 4 calibration standard, obtained. then compressed failure, elastic modulus, yield stress, strain, strain...
The authors examined factors influencing survival in 140 horses that recovered from anesthesia after small intestinal resection between 1968 and 1986, using Kaplan-Meier estimated curves the Cox proportional hazards regression model. Seventy-two (51%) died during initial postoperative period, 19 (14%) discharge hospital, 33 (24%) were alive, 16 (11%) classified as censored. Mean age at surgery was 8 years. Horses 15 years of or older, Arabians Stallions, overrepresented hospital population....
SUMMARY Storage and utilization of strain energy in the elastic tissues distal forelimb horse is thought to contribute excellent locomotory efficiency animal. However, structures that facilitate storage may also be exposed dangerously high forces, especially at fastest galloping speeds. In present study, experimental gait data were combined with a musculoskeletal model determine muscle joint contact loading muscle–tendon work during stance phase walking, trotting galloping. The flexor...
To compare hoof acceleration and ground reaction force (GRF) data among dirt, synthetic, turf surfaces in Thoroughbred racehorses.3 healthy racehorses.Forelimb accelerations GRFs were measured with an accelerometer a dynamometric horseshoe during trot canter on track at racecourse. Maxima, minima, temporal components, measure of vibration extracted from the data. Acceleration GRF variables compared statistically surfaces.The synthetic surface often had lowest peak accelerations, mean...
Abstract Objective To describe the prevalence, characteristics, and severity of soft-tissue osseous lesions in caudal portion thoracic lumbosacral vertebral column pelvis Thoroughbred racehorses. Animals 36 racehorses that died or were euthanatized at California racetracks between October 1993 July 1994. Procedure Lumbosacral pelvic specimens collected visually examined for lesions. Results Acute sacroiliac joint injury was observed 2 specimens. Signs chronic laxity subluxation not any...
Abstract Objective To evaluate selected shoe characteristics as risk factors for fatal musculoskeletal injury (FMI) and specifically suspensory apparatus failure (SAF) cannon bone condylar fracture (CDY) of Thoroughbred racehorses in California. Design Case-control study. Animals (n = 201) that died or were euthanatized at California racetracks between August 1992 July 1994. Procedure Shoe compared case horses affected by FMI (155), SAF (79), CDY (41) control reasons unrelated to the...
Abstract Objective To evaluate hoof size, shape, and balance as risk factors for catastrophic musculoskeletal injuries (CMI), including suspensory apparatus failure (SAF) cannon bone condylar fracture (CDY) in Thoroughbred racehorses. Animals 95 racehorses that died between 1994 1996. Procedure 38 quantitative measures of were obtained from orthogonal digital images the compared case horses with forelimb CMI (70), SAF (43), CDY (10) control whose death was unrelated to system (non-CMI, 25)....
Abstract Objective To investigate the relation between several racing speed history characteristics and risk of fatal skeletal injury (FSI) in Thoroughbreds. Animals 64 Thoroughbreds euthanatized during a 9-month period 1991 at California racemeet because catastrophic fracture incurred while (cases), identified retrospectively. For each race which an FSI occurred, 1 control horse was randomly selected from noncatastrophically injured participants. Procedure Racing officially timed workout...
Objective To investigate relationships of several racehorse characteristics and race conditions with risk a catastrophic musculoskeletal injury (CMI) resulting in euthanasia Thoroughbreds during racing California 1992. Design Retrospective longitudinal study. Animals that incurred CMI all entrants Procedure Necropsy records were reviewed, start information was obtained. Incidence CMI/1,000 estimated. Relationships between race-meet, entrant age sex, type length, surface condition evaluated...
To determine whether a two-month or longer period without official high-speed workouts (lay-up) is associated with humeral pelvic fracture in Thoroughbred racehorses.Reprospective study.Thoroughbred racehorses California that were euthanatized because of complete fracture.Age, sex, activity, number lay-ups, days from race timed workout to fracture, end last lay-up mean duration and total training compared between horses fractures fractures. A case-crossover study was used estimate relative...
Summary Thirty‐six Thoroughbred racehorses that died at California racetracks between October 1993 and July 1994 were evaluated for stress fractures in the caudal portion of thoracic lumbosacral regions spine pelvis. The pelvis collected, debrided soft tissues examined visually presence an incomplete fracture line focal periosteal proliferation, characteristic a fracture. Sixty‐one per cent specimens had evidence Vertebral lamina found 50% positively associated with severity dorsal spinous...
Abstract An important concept in bone mechanics is that osteons influence mechanical properties several ways, including contributing to toughness and fatigue strength by debonding from the interstitial matrix so as „bridge”︁ developing cracks. Observations of „pulled out„ on fracture surfaces are thought be indicative such behavior. We tested hypothesis osteon pullout varies with mode loading (fatigue vs. monotonic), cortical region, elastic modulus, life. Mid‐diaphseal beams dorsal, medial,...
To assess individual and combined associations of high-speed exercise horseshoe characteristics with risk forelimb proximal sesamoid bone fractures midbody in Thoroughbred racehorses.269 deceased racehorses.A case-control study design was used to compare 121 horses a fracture at least 1 4 bones (75 had fracture) 148 without fracture. Univariable multivariable logistic regression analyses were evaluate potential factors for association fracture.Compared that died fractures, more likely be...
