Our team has developed an AI software to guide the surgical protocol for femoral intertrochanteric fractures. This is a prospective randomized controlled clinical study that will include patients with femoral intertrochanteric fractures combining medial posterior and lateral wall fractures, and will randomly divide the patients into a traditional surgical protocol group and an AI-guided surgical protocol group. The efficacy and safety indexes such as operation time, blood loss, operation cost, infection rate, hospitalization time, postoperative pain score, fracture healing time, internal fixation failure rate and mortality rate were compared between the two groups to verify the efficacy and safety of AI-guided surgical treatment plan.

Inclusion Criteria:

1. Over 60 years old, male or female.
2. Osteoporosis intertrochanteric fracture, which met the diagnostic criteria of X-ray intertrochanteric fracture, and osteoporosis T-value <2.5.
3. Patients with 1mm resolution CT imaging data.
4. Willing to participate in the project, sign the informed consent, and be able to complete the follow-up work.

Exclusion Criteria:

1. Patients with pathological fractures, old fractures, stress fractures, and periprosthesis fractures;
2. Patients lacking 1mm resolution CT imaging data;
3. Severe malnutrition, heavy smoking, alcoholism and other systemic conditions affect fracture healing;
4. Patients with severe medical diseases that cannot be operated on;
5. Patients participating in other clinical studies.
