The Austin Moore Hip Prosthesis Long Stem is a femoral hemiarthroplasty implant designed for surgical management of displaced femoral neck fractures and related proximal femoral conditions. Built on one of orthopedics’ most established implant designs, the long-stem configuration provides added intramedullary support — particularly valuable in cases involving osteopenic bone or fracture patterns that extend into the subtrochanteric region.
Design and construction
The prosthesis features a polished spherical femoral head attached to a tapered intramedullary stem. Characteristic fenestrations along the stem facilitate bone ingrowth and contribute to biological fixation, making this a cementless device. The long stem provides greater stability within the femoral canal compared to standard-length variants, improving load distribution in challenging anatomical situations.
Available in premium stainless steel and titanium options, both materials offer the durability and biocompatibility expected in orthopedic implants of this type.
Intended applications
This implant is used in hemiarthroplasty procedures, most commonly for:
- Displaced femoral neck fractures
- Intertrochanteric fractures with subtrochanteric extension
- Avascular necrosis of the femoral head
- Femoral neck non-unions
It replaces the femoral head while retaining the patient’s native acetabulum, making it a unipolar prosthesis suitable for selected patient profiles.
Available options
- Head diameter: 30 mm to 60 mm
- Material: Premium stainless steel or titanium
Key specifications
- Type: Unipolar, uncemented femoral prosthesis
- Stem design: Long stem with fenestrations for osseointegration
- Head: Spherical, high-polish articulating surface
- Material options: Stainless steel / titanium
- Head size range: 30 mm to 60 mm
Surgeons and procurement professionals can select the appropriate head diameter from the 30 mm to 60 mm range and choose between stainless steel or titanium based on surgical requirements and patient anatomy.
