Topic:Hindlimb
The hindlimb of a horse is a complex anatomical structure that plays a vital role in locomotion, balance, and weight-bearing. Comprising the femur, tibia, fibula, tarsus, metatarsus, and phalanges, the hindlimb is connected to the pelvis through the coxofemoral joint. This structure is supported by a network of muscles, tendons, ligaments, and joints that facilitate movement and provide stability. The biomechanics of the hindlimb are essential for various equine activities, including walking, trotting, galloping, and jumping. Research in this area often focuses on the anatomy, physiology, and pathology of the hindlimb, exploring topics such as injury prevention, rehabilitation, and performance optimization. This page compiles peer-reviewed research studies and scholarly articles that investigate the structure, function, and clinical implications of the equine hindlimb.
Directional and anteroposterior asymmetry of common white markings in the legs of the Arabian horse: response to selection. Arabian bay horses manifest, on the average, more common white markings in their hind legs than their forelegs (anteroposterior asymmetry) and more common white markings in their left legs than their right legs (directional asymmetry). To determine if genetic variation exists for these types of asymmetry, the phenotypic response was studied in bay foals when their dams and sires were selected for the directions of fore-hind and left-right differences. In the fore-hind studies, the quantitative shifts in the bay foals were in the direction specified by the selection scheme and the observed devi...
Kinematic differences between the distal portions of the forelimbs and hind limbs of horses at the trot. In literature, it has been hypothesized that the concussion at impact in the equine forelimb is larger than that in the hind limb, and therefore, eventually more clinical lameness may develop in the distal portion of the forelimbs. As the functional anatomy of the distal forelimb and hind limb segments is similar, a study was undertaken to compare the kinematics of hoof and fetlock in the forelimbs and hind limbs. For this purpose, the trot of 24 clinically normal (sound) horses on a treadmill (4 m/s) was recorded, using modern gait analysis equipment. It appeared that vertical hoof velocity a...
Ligaments associated with joints. This article contains a short introduction to the anatomy, physiology, and pathophysiology of ligaments associated with diarthrodial joints. Individual ligaments are discussed on a regional basis as forelimb, distal limb, and hindlimb. Emphasis is placed on the anatomy of the ligaments because this is the key to sound clinical application of their involvement in joint disease. There are few conditions of diarthrodial joints that do not involve their associated ligaments, and this role may be in causative, diagnostic, and therapeutic or convalescent considerations.
Conservative treatment of an incomplete longbone fracture of a hindlimb of four horses. Four horses with an incomplete fracture of a hindlimb longbone were examined. In two, the tibia had been fractured by external trauma. In the other two horses proximal metatarsal 3 had fractured during normal activity. The diagnoses were made radiographically and the horses were treated conservatively by box rest. The fractures healed satisfactorily and the horses became sound.
Lameness attributable to osteochondral fragmentation of the plantar aspect of the proximal phalanx in horses: 19 cases (1981-1985). Osteochondral fragmentation of the plantar aspect of the proximal phalanx was diagnosed as a cause of hind limb lameness in 19 horses. The lameness was evident at the upper levels of the horses' performance capabilities, and was isolated to the metatarsophalangeal joints by use of intra-articular or regional anesthesia. Fragments were surgically removed from 10 horses that later returned to full use. Seven horses were treated intra-articularly with polysulfated glycosaminoglycans or corticosteroids; only one horse was able to return to full use. One horse was retired from work at the time of d...
The ground reaction force pattern from the hindlimb of the horse simulated by a spring model. A model consisting of a spring loaded by a time-dependent mass is presented simulating the vertical and longitudinal horizontal ground reaction force patterns obtained from the hindlimb of a walking horse.
