The goal of this study is to evaluate the difference of P1NP\/\u03b2\u2010CTX between trochanteric and femoral neck fractures and establish these two BTMs as independent risk factors for these two subtypes of hip fractures in the elderly.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>\n                      Following case\u2013control study design, 83 elderly patients with fragile hip fractures from two tertiary hospitals recruited between February 2023 to August 2024 were assigned into intertrochanteric fracture group (42 cases) and femoral neck fracture group (41 cases). Baseline characteristics including age, sex, height, weight, BMI, and history of diabetes\/Parkinson's disease were collected after admission. Besides, P1NP\/\u03b2\u2010CTX\/PTH\/25(OH)D blood tests and dual energy x\u2010ray absorptiometry (DXA) were performed on all participants before surgical operation. The statistical significances of categorical variables and continuous variables were established through\n                      <jats:italic>\u03c7<\/jats:italic>\n                      <jats:sup>2<\/jats:sup>\n                      \u2010tests and independent samples t\u2010tests, respectively.

Specifically, patients with trochanteric fractures showed a markedly higher value of P1NP than those with femoral neck fractures (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.044).

Furthermore, BMDs at trochanter and total hip regions in the trochanteric fracture group were significantly lower than those in the femoral neck fracture group (\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.028;\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.022).
