Association between myocyte quality control signaling and sarcopenia in old hip-fractured patients: Results from the Sarcopenia in HIp FracTure (SHIFT) exploratory study.

•Sarcopenia impacts the prognosis of older patients with hip fracture.•Alterations of myocyte quality control processes may be involved in sarcopenia.•Reduced mitochondrial fusion and autophagy signaling are associated with sarcopenia.•Myocyte quality control processes could be targeted for treating sarcopenia.
