The stem is especially suited to primary or revision cases where the calcar of the femur may be deficient and for cases of intertrochanteric fracture. ## Device Story Forged Co-Cr-Mo femoral stem for cemented total hip arthroplasty; features 2.25cm calcar platform for seating; available in one size, two lengths; design variation of existing Endurance hip stem with intermediate offset and no collar. Used by orthopedic surgeons in hospital settings for primary or revision hip replacement; addresses femoral calcar deficiency or intertrochanteric fractures. Provides structural replacement of hip joint; restores joint function. ## Clinical Evidence No clinical data provided; substantial equivalence based on design and material similarity to predicate devices. ## Technological Characteristics Material: Forged Co-Cr-Mo alloy. Design: Femoral stem with 2.25cm calcar platform, intermediate offset, collarless. Intended for cemented fixation. Class II device (21 CFR 888.3350). ## Regulatory Identification A hip joint metal/polymer semi-constrained cemented prosthesis is a device intended to be implanted to replace a hip joint. The device limits translation and rotation in one or more planes via the geometry of its articulating surfaces. It has no linkage across-the-joint. This generic type of device includes prostheses that have a femoral component made of alloys, such as cobalt-chromium-molybdenum, and an acetabular resurfacing component made of ultra-high molecular weight polyethylene and is limited to those prostheses intended for use with bone cement (§ 888.3027). ## Predicate Devices - DePuy Cemented Hip Stem (Endurance Hip Stem) - DePuy AML Calcar Hip Prosthesis ## Submission Summary (Full Text) > This content was OCRed from public FDA records by [Innolitics](https://innolitics.com).

The design of the stem is similar to the design of the size 3 DePuy Cemented Hip Stem (now called the Endurance hip stem) except that the Endurance Calcar has an offset that is midway between the standard and high offset Endurance stems, does not have a collar and does have a 2.25cm calcar platform which is used to seat the implant. The Endurance Calcar Hip Prosthesis is indicated for cemented use as the femoral component in total hip arthroplasty (THA) for replacing the hip joint of patients whose hip joint has been damaged by inflammatory or non-inflammatory degenerative joint disease, fracture or the failure of a previous arthroplasty. The stem is especially suited to primary or revision cases where the calcar of the femur may be deficient and for cases of intertrochanteric fracture. # BASIS OF SUBSTANTIAL EQUIVALENCE: The Endurance Calcar Hip Stem is similar to the Endurance Hip Stem in that they have the same basic design, are manufactured from the same material and are both intended for use in cemented total hip arthroplasty. The Endurance Calcar Hip Stem is similar to the AML Calcar Hip Stem in that both stems have calcar platforms, are intended for use in cemented total hip arthroplasty, and can be used in cases where the calcar of the femur is deficient. 000012 --- **Source:** [https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/JDI/K961619](https://fda.innolitics.com/submissions/OR/subpart-d%E2%80%94prosthetic-devices/JDI/K961619) **Published by [Innolitics](https://innolitics.com)** — a medical-device software consultancy.
