Abstract ObjectiveTo investigate whether the Garden index can determine the rotational displacement of femoral neck fracture. MethodsTen healthy human femoral specimens were obtained. A 2.0 mm diameter Kirschner-wire was placed in the center of the femoral head. The osteotomy was perpendicular in the middle of the femoral neck. The distal osteotomy surface was indicated the angle of rotation (pronation and supination to 90°, every 10° was an interval). The X-ray of anterior-posterior and lateral view was taken at different angles according to the mark. The Garden index and other relevant data were analyzed with the PCAS system. Meanwhile, the change of the area of the femoral head fovea at different rotation angles was observed. ResultsThere was no significant difference in the Garden index in 0~30° at pronation and supination position (P>0.05). In range of 40°~90°, there was a statistical difference in the Garden index (P<0.05). With the increase of the pronation angle, the area of the femoral head fovea is gradually reduced; as the angle of the supination increases, the area of the femoral head fovea is gradually increased. ConclusionThe Garden Index cannot accurately determine the rotational displacement of the femoral neck fracture during the pronation or supination range of 0~30°. Changes in the area of the femoral head fovea can help determine the rotational displacement of the femoral neck fracture.Level of EvidenceLevel V.

Introduction Internal fixation of undisplaced intracapsular femoral neck fractures with cannulated hip screws is a widely accepted surgical technique, despite reported failure rates of 12%–19%. This study determined whether preoperative serum albumin levels are linked to fixation failure. Methods We retrospectively reviewed 251 consecutive undisplaced intracapsular femoral neck fracture patients treated with cannulated hip screws in a district general hospital. Preoperative albumin levels were measured, and the fixation technique, classification and posterior tilt on radiography assessed. Fixation failure was defined as a screw cut, avascular necrosis (AVN) or non-union. Results Of the patients, 185 were female and 66 male. The mean age was 77 years (range 60–101 years). Thirty seven (15%) patients had fixation failure: 10 (4%) due to AVN; 12 (5%) due to non-union; and 15 (6%) due to fixation collapse. Low serum albumin levels were significantly associated with failure (p=0.01), whereas gender (p=0.56), operated side (p=0.62), age (p=0.34) and screw configuration (p=0.42) were not. A posterior tilt angle greater than 20° on lateral radiography significantly predicted failure (p=0.002). Conclusions Preoperative serum albumin is an independent predictor of cannulated hip screw fixation failure in undisplaced femoral neck fractures. Nutritional status should therefore be considered when deciding between surgical fixation and arthroplasty to avoid the possibility of revision surgery, along with an increased risk of morbidity and mortality.

Aims The aim of this study was to investigate the potentially increased risk of dislocation in patients with neurological disease who sustain a femoral neck fracture, as it is unclear whether they should undergo total hip arthroplasty (THA) or hemiarthroplasty (HA). A secondary aim was to investgate whether dual-mobility components confer a reduced risk of dislocation in these patients. Methods We undertook a longitudinal cohort study linking the Swedish Hip Arthroplasty Register with the National Patient Register, including patients with a neurological disease presenting with a femoral neck fracture and treated with HA, a conventional THA (cTHA) with femoral head size of ≤ 32 mm, or a dual-mobility component THA (DMC-THA) between 2005 and 2014. The dislocation rate at one- and three-year revision, reoperation, and mortality rates were recorded. Cox multivariate regression models were fitted to calculate adjusted hazard ratios (HRs). Results A total of 9,638 patients with a neurological disease who also underwent unilateral arthroplasty for a femoral neck fracture were included in the study. The one-year dislocation rate was 3.7% after HA, 8.8% after cTHA < 32 mm), 5.9% after cTHA (= 32 mm), and 2.7% after DMC-THA. A higher risk of dislocation was associated with cTHA (< 32 mm) compared with HA (HR 1.90 (95% confidence interval (CI) 1.26 to 2.86); p = 0.002). There was no difference in the risk of dislocation with DMC-THA (HR 0.68 (95% CI 0.26 to 1.84); p = 0.451) or cTHA (= 32 mm) (HR 1.54 (95% CI 0.94 to 2.51); p = 0.083). There were no differences in the rate of reoperation and revision-free survival between the different types of prosthesis and sizes of femoral head. Conclusion Patients with a neurological disease who sustain a femoral neck fracture have similar rates of dislocation after undergoing HA or DMC-THA. Most patients with a neurological disease are not eligible for THA and should thus undergo HA, whereas those eligible for THA could benefit from a DMC-THA.

Introduction: The aim of this study was to determine the diagnostic value of single-photon emission computed tomography/computed tomography (SPECT/CT) in prediction of avascular necrosis (AVN) after femoral neck fracture and to evaluate whether photon defect in femoral head as seen in SPECT/CT can be an index for choice of surgical method. Methods: This study was based on 97 patients who took SPECT/CT after femoral neck fracture from November 2012 to November 2017, with 64 patients with femoral intertrochanteric fracture in which chances of AVN is rare as a comparison group. Among 97 patients with femoral neck fracture, osteosynthesis was conducted in 7 patients with less than 15% of photon defect in damaged femoral head and 7 patients who wanted osteosynthesis, despite photon defect more than 15%, and 83 patients with photon defect more than 25% had arthroplasty. Patient with osteosynthesis was followed up with AVN by conducting magnetic resonance imaging (MRI) in 1 year after the surgery. Results: Quantitative analysis of SPECT/CT in 14 patients who had femoral neck osteosynthesis showed that 7 patients with femoral neck fracture showed photon defect of 15% or more, but less than 25% and 3 patients in these were diagnosed with AVN after 1-year follow-up by MRI. Sensitivity and specificity of SPECT/CT in predicting AVN was 100% and 63.6%, respectively, with prediction accuracy of 71.4%. Among 14 patients with femoral neck fracture who had osteosynthesis, photon defect in 3 patients diagnosed with AVN was 19.6% ± 5.2%, but photon defect in 11 patients who was not diagnosed with AVN was 10.7% ± 5.2%, showing statistically significant difference between 2 groups ( P = .001). Conclusion: Single-photon emission computed tomography/CT in patients with femoral neck fracture is considered to have diagnostic value in predicting occurrence of AVN, and percentage of photon defect is considered to be an useful index in determining the operative method.
