Cementless short-stem shoulder arthroplasty yielded good functional, radiologic results at 2 years
Patients who underwent cementless short-stem shoulder arthroplasty experienced good functional and radiologic results at a minimum follow-up of 2 years, according to study results.
Researchers evaluated 52 patients with uncemented short-stem shoulder arthroplasties and analyzed their radiographs for inclination of the stem, filling ratio of metaphysis and diaphysis, bone remodeling around the stem, radiolucent lines around the glenoid and subsidence of the humeral stem. Researchers also compared radiographic and clinical findings between patients with low and high bone adaptations.
Results showed no loosening, subsidence or osteolysis at final follow-up. Researchers found high bone adaptations in 51.9% of patients, with patients with high bone adaptations experiencing a significantly higher metaphyseal and diaphyseal filling ratio vs. patients with low bone adaptations at 2-year follow-up. The most frequently occurring bone adaptations included cortical thinning and osteopenia in the medial cortex and sport welds in the lateral cortex, according to results. Researchers noted radiographic changes did not influence clinical outcomes. – by Casey Tingle
