Дегенеративное заболевание суставов
Also known as: Остеоартроз лошадей
Дегенеративное заболевание суставов (остеоартроз) — прогрессирующее разрушение суставного хряща и окружающей кости у лошадей и ослов. Это ведущая причина хронической хромоты, особенно у спортивных и стареющих животных. Поражённые суставы со временем становятся скованными, болезненными и теряют объём движений.

Overview
Degenerative joint disease, or osteoarthritis, is progressive breakdown of articular cartilage with secondary changes in bone and the joint capsule. It is one of the most common causes of chronic lameness and reduced performance in horses and a frequent problem in aging donkeys.
Causes
Repetitive concussion and stress, joint instability, previous injury, intra-articular fractures, infection, conformational faults, and developmental disease all contribute. Wear accumulates over years, especially in hardworking and older animals.
Signs
Signs include lameness that often worsens with work, joint stiffness and reduced flexibility, joint swelling, heat, and a shortened stride. Donkeys may mask discomfort and simply move less or lose condition.
Diagnosis
Lameness examination with flexion tests, diagnostic joint blocks, and radiographs showing narrowed joint space and bony spurs confirm the diagnosis; ultrasound and MRI assess soft tissues.
Treatment & Management
Management includes controlled exercise, weight control, anti-inflammatory drugs, joint injections, corrective farriery, and joint-supportive medications. The goal is to relieve pain and slow progression.
Prevention
Appropriate workloads, good footing, balanced hoof care, weight control, and prompt treatment of joint injuries help delay onset.
