Introduction. Proximal humeral fractures (PHF) are a frequent finding, and still growing part of it needs to be treated operatively. Extending life expectancy, increasing percentage of osteoporotic fractures and progressive patients’ demand force surgeons to seek the best solutions of treating complex fractures. Just some teen years ago older patients who suffered a severe PHF were doomed to shoulder dysfunction. Today we can offer them a reversed shoulder arthroplasty (RSA) Purpose. The aim of the paper was a clinical evaluation of the patients who were treated with RSA in a Regional Hospital. Material and Methods. In years 2017-2021 in our department there were performed 41 RSAs and 5 TSAa (total anatomic shoulder arthroplasty). Earlier in 2010-2017 we performed 26 hemiarthroplasties. The procedures were done via delto-pectoral approach. The implant used were Aequalis Reversed Fracture (Tornier) and SMR (Lima). Results. The patients were evaluated in a simplified manner after 6 months postop. Functional active range of motion and VAS score were noted. Conclusions. In our department RSA is a well adopted method of treating complex PHFs, especially in elderly patients, and it yields overall good results and great percentage of satisfied patients.

Chondral lesions following an injury to the knee joint have poor healing potential and may lead to osteoarthritis. Nowadays, more and more research is focused on tissue regeneration and the prevention of osteoarthritis development. Efforts to restore the articular cartilage using advanced procedures like autologous chondrocyte implantation led to the development of scaffolds. Although the use of a scaffold-based technique is a reliable and effective method of cartilage repair, only the appropriate qualification can lead to good clinical outcomes.

Dr Kazimierz Grzebień was born in November26, 1928 in Kościerzyna. He received his medical degree at the Faculty of Medicine at the Medical Academy of Poznań on November 11, 1953 and started to work at the Orthopedic Clinic in Poznań, headed by prof. Wiktor Dega.

On every occasion he made note of the brilliant and innovative method of treatments and rehabilitation applied by Prof. Wiktor Dega. He died on December 14, 2003, on the day of the opening of the symposium in Warsaw celebrating the 75th anniversary of Polish orthopedics, of which he was a great luminary.
