Our study aims to identify the prevalence of low vitamin D status in patients undergoing total hip arthroplasty (THA) and to evaluate the association between serum vitamin D level and the attainment of in-hospital functional milestones. We collected data from patients who underwent THA and had preoperative serum vitamin D (serum 25-hydroxy vitamin D) levels measured. From 200 patients, 79 (39.5%) had low serum vitamin D (serum 25-hydroxy vitamin D <32 ng/mL). There were no associations between serum vitamin D level and the attainment of in-hospital functional milestones as well as length of hospital stay or perioperative complications after THA. Because low vitamin D status did not compromise the short-term functional outcomes after THA, surgery need not be delayed, but low vitamin D levels should be corrected once identified.
我们的研究旨在确定接受全髋关节置换术（THA）的患者中维生素 D 水平低下的患病率，并评估血清维生素 D 水平与住院期间功能里程碑的达成之间的关联。我们收集了接受 THA 并测量了术前血清维生素 D（血清 25-羟维生素 D）水平的患者的数据。在 200 名患者中，有 79 名（39.5%）存在血清维生素 D 水平低下（血清 25-羟维生素 D <32ng/mL）。血清维生素 D 水平与住院期间功能里程碑的达成、住院时间或 THA 后围手术期并发症之间均无关联。由于维生素 D 水平低下并不影响 THA 后的短期功能结局，因此无需延迟手术，但一旦发现低维生素 D 水平应予以纠正。
