● Introduction
Canine hip luxation is one of the most common orthopedic emergencies in dogs, characterized by the displacement of the femoral head from the acetabulum, resulting in joint dysfunction and pain.
Trauma is the most frequent cause, including incidents such as car accidents, falls from heights, intense activity, or direct impact. In addition to traumatic factors, other common causes include hip dysplasia, ligamentous laxity, and degenerative joint disease.
In this case study, we explore the real-world application and remarkable outcomes of using ETButton in treating hip luxation, through the experience of a Border Collie named Tianlang.

● Basic Information
· Name: Tianlang
· Breed: Border Collie
· Sex: Male
· Age: 5 years
· Weight: 22 kg
· Chief Complaint: Pain after exercise, non-weight-bearing lameness in the left hind limb for approximately 2 days. Radiographs taken at other clinic confirmed left femoral head luxation.

● Pre-op Assessment
Physical Examination
· General condition: No significant abnormalities observed
· Mucous membrane color: Pink
· Body Condition Score: 6/10
· Muscle Condition Score: Normal
· Periodontal Score: Normal

▼ Pre-op Imaging

▲ Diagnosis: Left femoral head luxation

● Treatment Plan

● Discussion & Conclusion
Current surgical options for treating canine hip luxation include:
· Artificial ligament reconstruction
· Total hip replacement
· Femoral head and neck ostectomy (FHO)
Advantages of Artificial Ligament Reconstruction:
1. Preserves joint function and reduces abnormal joint stress
2. Minimally invasive with faster recovery
3. Excellent functional prognosis with proper rehabilitation
Artificial ligament reconstruction is an ideal choice for traumatic hip luxation, particularly when ligament injury is the primary concern. With the aid of structured rehabilitation, outcomes can be further improved.
ETButton represents an innovative solution for hip ligament repair, filling a critical gap in current treatment options.
Its advanced design provides a more precise and stable fixation, offering veterinary professionals and patients a reliable alternative for hip luxation management.
