Short term results of anatomic stemless shoulder replacement with peripheral neck fixation.

Background: Most of the current stemless implants are using a central neck fixation design. Easytech Stemless replacements (FX Solutions®, Viriat, France) were developed promoting the idea of peripheral fixation of the stemless implant. The aim of this study was to analyze clinical and radiological results of this stemless TSA implanted for osteoarthritis (OA).

Mid-Term to Long-Term Follow-Up of Stemless Anatomic Total Shoulder Arthroplasty.

Background: The purpose was to report mid-term to long-term clinical outcomes in a multicentre series of patients who received stemless total shoulder arthroplasty (TSA). The hypothesis was that stemless TSA would be a safe and effective treatment with satisfactory clinical outcomes.

Methods: Authors retrospectively reviewed records of 62 stemless TSAs implanted between March 2013 and December 2014.

Stemless reverse shoulder arthroplasty: clinical and radiologic outcomes with minimum 2 years' follow-up.

Background: Recently, a stemless reverse shoulder arthroplasty (RSA) design was developed to preserve bone stock. Clinical and radiologic studies of this design in larger cohorts with >100 patients are not frequent. The purpose of this study was to present the clinical and radiologic results of a newly developed stemless RSA implant.

Two-year outcome of hydroxyapatite-coated prostheses. Two femoral prostheses retrieved at autopsy.

We performed a histological study of the bone-implant interface on 2 human femurs implanted with a hydroxyapatite-coated self-locking stem for 2 years. Extensive bone formation with no intervening fibrous tissue was noted around the entire circumference of the 2 prostheses. The newly-formed bone had 2 morphotypes: an alveolar disposition with a continuous contact between bone and hydroxyapatite, and a digitiform one where distinct bony trabeculae were in contact with the ceramic coating or with the bone marrow.
