Highlights • Birmingham Mid-Head Resection (BMHR) prostheses are implants used to treat hip osteoarthritis in young patients with the goal of preserving as much bone stock as possible.• Compared to total hip arthroplasty, BMHR prostheses offer advantages such as lower rate of dislocation and lower rate of infection and sepsis.• The revision rate of BMHR devices is higher than that of conventional total hip arthroplasty devices. Furthermore, these revisions occur earlier with the former.• The main complication of BMHR prostheses are femoral neck fratures, which are also the most common reason for revision.• Patterns of BMHR periprosthetic fractures usually described in the literature are subcapital and transcervical ones. Nevertheless, more patterns can be found and different therapeutic attitudes must be adopted.
