Minimally Invasive Hip Surgery

1. Minimally Invasive Hip Surgery

2. What is Minimally Invasive Hip Surgery? • A new surgical technique • Uses traditional hip implants. • Two different techniques, including mini-incision and two-incision.

3. Traditional Hip Replacement Surgery Proven in clinical studies and successfully performed for decades Allows surgeon full visualization of operative area Larger incision (8-10 inches) More disruption of muscles and tissues Minimally Invasive Hip Replacement Surgery Long-term effects and success are not established. Restricted visualization of operation area. Smaller incisions (2-4 inches) Potentially less disruption of muscles and tissues May lead to less blood loss and postoperative pain Traditional VS Minimally Invasive Hip Replacement Surgery

4. Traditional Hip Replacement Surgery Average hospital stay is five days Average recovery time of approx. 3 months (individuals will vary) Minimally Invasive Hip Replacement Surgery May lead to a shortened hospital stay, less than 5 days. May reduce recovery time Traditional VS Minimally Invasive Hip Replacement Surgery

6. Benefits of Minimally Invasive Hip Surgery • Less trauma to the body. • Healing and rehabilitation potentially quicker. • Shorter hospital stays • Allows for immediate stability of the hip • Lower risk of dislocation. • Potentially less postoperative pain. • Cosmetically appealing

7. Ideal Candidate • Suffering from hip arthritis • Failed response to: • Medicines • Exercise • Weight-management • Deciding factors include: • Medical history • Weight • General health • Body structure, including bone structure • Extent and pattern of arthritis

8. Inappropriate Candidates • Severely obese (BMI of 40 or greater) • Very muscular • Undergoing complex revision surgeries

9. Two-Incision 2 incisions Approximately 2 inches in length On both front and rear of thigh Fluoroscopy may be used. Mini-Incision 1 incision Approximately 3 to 4 inches in length Either front or rear of thigh Fluoroscopy is not used. Minimally Invasive Hip Techniques

10. Two-Incision Mini-Incision Techniques: Two Incision vs Mini Incision

11. Fluoroscopy • Real-time x-ray images to define instruments positions during surgery. • Guides position of implants • Sometimes used with smaller incisions.

12. Fluoroscopy: Benefits and Risks • Benefits: • Increases surgical accuracy • Safer and shorter procedure. • Risks: • Increased radiation exposure • Minimal long term effects

13. Recovery After Surgery • MIH benefits shown in the first 3 months of recovery • Patient must follow hip precautions: • Not crossing their legs • Take care when bending • Avoid high-impact and contact sports.

14. Risk Factors • Factors that may affect the rate of complications including • Surgeon skill • Weight, age and overall health of the patient • Current lifestyle and activities of the patient • Presence of osteoporosis or other conditions that weaken bones • Patient compliance with physician instructions

15. Potential Complications and Risks • Hematoma • Occurs when blood enters the wound after surgery. • If excessive, will be drained. • Hip Fracture • Occurs during or after surgery • Caused by: • Weak bones • Falling • Failure to follow hip precautions

16. Potential Complications and Risks • Infection • About 1% change of infection after surgery • Dislocation • Occurs when the ball of the hip comes out of the socket. • Caused by: • size • Blood clots
