The inclusion criteria were: (i) patients aged \u226560\u2009years; (ii) patients with recent femoral neck fracture, with times of injury ranging from 12\u201372\u2009h; and (iii) patients who underwent Garden II\u2013IV closed reduction and internal fixation. Patients were classified based on the Garden fracture type and Pauwels angle. Clinical data and radiographs before and after the surgery were collected. Subsequently, surgery was performed with the patient in supine position, under general or lumbar epidural anesthesia. Closed reduction was performed until satisfactory fracture reduction quality was achieved. The weight of all included patients were\u2009&lt;75\u2009kg, and thus, minimal internal fixation was performed. The ischemic necrosis of the femoral head was diagnosed by considering the symptoms, signs, and radiological findings. Harris hip scores were used to evaluate postoperative recovery of hip function. Furthermore, relationships between Garden fracture type and necrosis rate of the femoral head, Pauwels angle and necrosis rate of the femoral head, Garden fracture type and Harris hip score, and age and Harris hip score were analyzed.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The mean duration of surgery was 1\u2009\u00b1\u20090.17\u2009h and blood loss for all the patients was approximately 15\u2009mL. The included patients were followed up for 13\u2013128\u2009months, with an average follow\u2010up of 61\u2009months. Among the included 73 patients, 65 (89.0%) exhibited satisfactory union, seven (9.6%) had femoral head necrosis, and one (1.4%) had nonunion. For seven patients with femoral head necrosis, there were two, two, and three patients classified as Garden IV, Garden III, and Garden II, respectively, and two and five patients classified as Pauwels II and Pauwels III, respectively. Among the seven cases, four underwent hip replacement. Garden fracture type was not significantly associated with femoral head necrosis (\u03c7<jats:sup>2<\/jats:sup> = 0.44, <jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05) or Harris score (\u03c7<jats:sup>2<\/jats:sup> = 1.43, <jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05).
