Abstract：
UNASSIGNED: A delay in the diagnosis and treatment of an occult femoral neck fracture (OFNF) can negatively affect the subsequent quality of life. We investigated the diagnostic accuracy of ultrasonography for OFNF in patients confirmed with this condition by magnetic resonance imaging (MRI), and compared these results with other clinical findings.
UNASSIGNED: Ninety-four outpatients aged above 70 years with acute hip pain but without radiographic abnormal findings who were suspected of having an occult femoral neck fracture (11 men and 83 women with a mean age of 81.8 ± 6.0 years) were enrolled. Both ultrasonography and MRI were performed in all cases within 24 h. The ultrasonographic distance between the anterior aspect of the femoral neck and the anterior joint capsule (ultrasound joint swelling) was measured.
UNASSIGNED: By MRI findings, 27 patients were assigned to an occult femoral neck fracture (OFNF) group (1 man, 26 women) and 67 patients to a non-OFNF group (10 men, 57 women). The mean ultrasound joint swelling in both groups was 7.53 ± 1.52 mm and 3.45 ± 0.89 mm, respectively (p = 0.006, 95% CI, 3.58-4.59). A cut-off value of 5.3 mm showed a sensitivity of 0.96 (0.89-0.96) and a specificity of 0.98 (0.92-1.00).
UNASSIGNED: Ultrasonography shows very high diagnostic accuracy for occult femoral neck fracture. This modality can thus contribute to initial bed-side examinations for this condition in patients over 70 years with acute hip pain.

摘要：
UNASSIGNED：隐匿性股骨颈骨折（OFNF）的诊断和治疗延迟会对随后的生活质量产生负面影响。我们调查了通过磁共振成像（MRI）证实患有这种疾病的患者的超声检查对OFNF的诊断准确性，并将这些结果与其他临床发现进行了比较。
UNASSIGNED：纳入94名年龄在70岁以上的急性髋部疼痛患者，但没有影像学异常发现，怀疑患有隐匿性股骨颈骨折（11名男性和83名女性，平均年龄为81.8±6.0岁）。所有病例均在24h内进行超声和MRI检查。测量股骨颈前部与前关节囊之间的超声距离（超声关节肿胀）。
未经证实：通过MRI发现，27例患者被分配到隐匿性股骨颈骨折(OFNF)组(1例,26名女性）和非OFNF组的67名患者（10名男性，57名妇女）。两组超声关节肿胀平均为7.53±1.52mm和3.45±0.89mm,分别为(p=0.006，95%CI，3.58-4.59)。5.3mm的截断值显示0.96(0.89-0.96)的灵敏度和0.98(0.92-1.00)的特异性。
UASSIGNED：超声检查显示隐匿性股骨颈骨折的诊断准确性非常高。因此，这种方式可以为70岁以上急性髋部疼痛患者的这种情况进行初始床边检查。
