Data on demographics, medical history, fracture pattern (Vancouver Classification), injury mechanism, radiological findings (e.g., osteoporosis via the Singh index), bone healing (RUSH score), bone resorption, non-union, surgical treatment, and clinical outcomes were extracted.

The most common potential risk factors for PFF were uncemented stem components (69%), bone resorption (68%), female sex (70%), and osteoporosis (21%). Hospital stay was longest for B2 and B3 fractures, with B3 fractures requiring the longest intensive care unit time (mean of 3\u2009\u00b1\u20094 days,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.041). Complications included wound infections (12%), urinary tract infections (20%) and postoperative anemia (51%). Osteoporosis was correlated with female sex and a higher risk of non-union, but did not influence bone healing.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusions<\/jats:title>\n                    <jats:p>PFF present clinical challenges, with fracture type and complications influencing hospital stay and postoperative mobility.
