FAQ
1. Which patients are suitable for this hip prosthesis?
(1) Younger patients: Ideal for those with good proximal bone quality and a high activity level.
(2) Mild bone deficiency: Suitable for patients with only slight bone loss.
(3) Anatomical considerations: Designed for patients with atypical femoral shaft anatomy or those who require additional fixation.
(4) Developmental dysplasia of the hip (DDH): Can be considered for select DDH cases.
A physician evaluation is required to determine surgical suitability.
2. Can patients undergo MRI scans after implantation?
Yes, the implant is made from non-magnetic materials like titanium, titanium alloys, and cobalt-chromium-molybdenum alloys, ensuring MRI safety. JUST MEDICAL's products meet these standards, but always inform your radiologist before scanning.
3. Does this product support cemented or cementless fixation?
Designed exclusively for cementless fixation.
Promotes excellent long-term bone growth for stable and durable fixation. Eliminates the need for bone cement.
4. What are the surgical advantages?
Smaller incision (30-40% reduction vs conventional stems)
Bone-preserving femoral preparation
Reduced blood loss and faster recovery
5. What materials and coatings are used for the MINI™ Stem?
The stem is manufactured from high-strength Ti6Al4V alloy. It features a Ti+HA (Vacuum Plasma Sprayed) proximal coating that provides extensive bone ingrowth for secure biological fixation.
6. What sizing specifications are available for the MINI™ Stem?
The stem is available in sizes 6# through 15#, featuring a 1mm increment in M/L width and a 2mm increment in stem length to accommodate varying patient anatomies. It is designed with a 130° neck angle.
