Stanmore Cemented Stem

Over 1 million times per year, Biomet helps one surgeon

provide personalized care to one patient.

The science and art of medical care is to provide the right

solution for each individual patient. This requires clinical

mastery, a human connection between the surgeon and the

patient, and the right tools for each situation.

At Biomet, we strive to view our work through the eyes of

one surgeon and one patient. We treat every solution we

provide as if it’s meant for a family member.

Our approach to innovation creates real solutions that assist

each surgeon in the delivery of durable personalized care

to each patient, whether that solution requires a minimally

invasive surgical technique, advanced biomaterials or a

patient-matched implant.

When one surgeon connects with one patient to provide

personalized care, the promise of medicine is fulfilled.

One Surgeon. One Patient.

Stanmore Cemented Hip Stem30 Years of Clinical Success

The Stanmore hip was designed by Professor

John Scales, OBE, and Mr John Wilson, OBE.

The first stem was implanted in 1973 following its

development at the Royal National Orthopaedic

Hospital, Stanmore, England, and the Institute

of Orthopaedics, University of London. Since

1987 over 98,700 stems have been implanted

worldwide.1

Clinical Success of the Stanmore Hip Stem

91% Survivorship at 22 years follow-up in 135 patients2

73% Survivorship at 20 years, in 807 patients3

86% Survivorship at 14 years vs. 79% survivorship for the Charnley stem4

97.5% Survivorship at 10 year follow-up in 636 patients5

89.9% Survivorship at 10 year follow-up, in 105 patients6

90% Survivorship at 10 year follow-up in 57 young patients with a mean age of 41 years old

99% Survivorship at 5 year follow-up, in 97 patients7

98.2% Survivorship at 5 year follow-up, in 249 patients8

98% Survivorship at 5 year follow-up, in 2938 patients9

Stanmore Cemented Hip StemProven Design Principle

Standard and Lateralised Neck Angles

Enhanced soft tissue tension and joint stability can be achieved by exchanging the 130° standard stem with the lateralised 125° stem

Collared Stem

The collar prevents subsidence to attain strong fixation of the implant to the cement

Straight and Standard Stem geometry

The horizontal offsets range from 33.5 mm to 48.5 mm to successfully restore the hip biomechanics

Type One Biomet Taper

The taper allows for use with an array of CoCr and Delta ceramic heads, up to 40 mm diameter, to benefit the joint stability and patient range of motion

The Stanmore femoral stem is a trusted device

with excellent long-term clinical success for over

30 years. The Stanmore stem geometry and

surface finish have remained unchanged, building

clinical longevity to become a gauge of lasting

improvement in patients’ life.11

Stanmore Cemented Hip Stem

Satin Surface Finish

The wet blasted surface treatment creates a smooth sating finish (0.75Ra), optimal for mechanical bonding between the implant and the bone cement

Rectangular Cross-Section

The stem cross-section enhances the implant rotational stability in the femur

Tapered Stem Geometry

The 4.5° M/L and 1.4° A/P angle facilitate the stem insertion in the cement

CoCrMo Alloy

The high stiffness of the material decreases the risks of cement stresses.The high strength of the alloy reduces the risk of prosthetic fractures compared to stainless steel stems

Stanmore Cemented Hip StemFromPrimarytoRevision

In addition to the standard and lateralised primary

stems, Stanmore combines an unsurpassed

primary system with a proven revision technique.

The revision stems range from 196 to 214 mm

(measurements from the calcar), and have the

same proximal geometry as the standard and

straight primary stems. Amongst other applications,

it can be selected in the management of Paprosky

type one revision surgery.

Stanmore Cemented Hip StemModern Instrument platform

Biomet is the only orthopaedic company that offers a 10 year limited warranty on specific products, in particular on the Stanmore stem. The Warranty procedure is simple, quick, with minimal paperwork, allowing Biomet Clinical Research Department to rapidly initiate the warranty for revision cases. Should warranted implants require revision within 10 years after the implantation date, Biomet will provide a free of charge replacement implant for the revision operation.

The instrumentation enables a reproducible and

easy technique, allowing optimal restoration of the

joint biomechanics and reduced pain.

10 Year Warranty Programme – When confidence is Key

The 10 year limited warranty is not offered in every country. Please contact your local Biomet Clinical Research Department for more information about the Warranty Programme and its availability in your country.
