Complications of Equine Musculoskeletal Surgery and Procedures.

Overview

• The article reviews common complications that arise during and after equine musculoskeletal surgeries and procedures.
• It is specifically targeted toward primary equine veterinarians performing these interventions to help them better manage and treat complications.

Detailed Explanation

Scope of Complications in Equine Musculoskeletal Procedures

• Complications are described as an unavoidable aspect of musculoskeletal surgeries and procedures in horses.
• The article covers a broad range of surgeries and procedures that involve the bones, joints, muscles, tendons, and ligaments of horses.
• Awareness of these complications is critical to enable timely identification and appropriate management, improving patient outcomes.

Types of Procedures Covered

• Musculoskeletal diagnostic procedures: These may include diagnostic imaging, arthrocentesis, or biopsies and can carry risks such as infection or tissue damage.
• Correction of angular and flexural limb deformities: Surgeries or interventions to address abnormal limb angulation or joint flexion, which can involve complications like incomplete correction, overcorrection, or growth disturbances.
• Muscle, tendon, and ligament surgeries: Procedures to repair or reconstruct soft tissue structures, with risks such as tendon rupture, adhesion formation, or delayed healing.
• Surgery of the foot: Including procedures on the hoof and distal limb, which may have complications like infection, laminitis, or poor wound healing.
• Orthopedic and arthroscopic surgeries: Involving bone and joint interventions, with complications potentially including joint infection (septic arthritis), implant failure, or cartilage damage.
• Cast management: Used postoperatively for immobilization but can lead to complications like pressure sores, swelling, or cast loosening.

Commonly Encountered Complications

• Infections: Resulting from surgical site contamination leading to cellulitis, abscess, or osteomyelitis.
• Delayed or poor wound healing: Due to vascular compromise, excessive tension, or contamination.
• Mechanical complications: Such as failure of implants, fracture displacement, or soft tissue damage.
• Neurological injury: From nerve entrapment or trauma during surgery.
• Overcorrection or undercorrection of deformities: Leading to limb dysfunction or the need for additional procedures.
• Adhesion and fibrosis: Causing restriction of joint or tendon movement and requiring intervention.
• Cast-related complications: Pressure necrosis, swelling causing compartment syndrome, or slippage of the cast.

Diagnostic and Treatment Considerations

• Early recognition of complications via clinical examination, imaging, and laboratory tests is essential.
• Treatment may include antibiotics for infections, surgical revision, wound care protocols, and supportive therapies like physical rehabilitation.
• Prevention strategies discussed involve meticulous surgical technique, appropriate perioperative care, and careful postoperative monitoring.
• Management plans should be individualized per patient and complication severity, involving referral when necessary.

Practical Value for Veterinarians

• The article serves as a guide for primary equine veterinarians, consolidating knowledge about potential surgical complications and their management.
• It empowers practitioners with information to improve early detection and outcome optimization.
• This resource supports decision-making around when to intervene and when to refer, contributing to better welfare and prognosis for equine patients undergoing musculoskeletal procedures.
