Brief summary
Patients treated operative for Proximal humeral fractures with angular stable device (Philos plate or ALPS-PHP)
Detailed description
From a cohort of patients treated for displaced Proximal humeral fractures (PHF) in the period July 2017 - August 2019 patients with the 11-B2 and 11-C2 PHF according to AO/OTA 2007 fracture classification were selected according to age and gender to be compared with patients operated with a Philos plate within the same fracture group, age and gender to be matched for adverse events: 1. Radiographic evidence of penetration of pegs (ALPS-PHP) or screws (Philos) into the glenohumeral joint (primary outcome) and 2. Avascular head necrosis / sinking / need of re-surgery 3. Clinical PROMS
