未经证实:肌肉和骨骼形态测量可能是预测股骨转子下缩短截骨术(FSSO)的有效指标。我们旨在研究可能预测FSSO的肌肉和骨骼因素。
UNASSIGNED:接受单侧Crowe4型髋关节发育不良(DDH)的患者没有(第1组,31例)和FSSO(第2组,39例)进行单侧全髋关节置换术(THA)。选择60例健康臀部(第3组)作为对照组。在X射线照片和计算机断层扫描(CT)图像上,在手术(O)和非手术(NO)臀部上测量了一些肌肉和骨骼参数。
未经证实:平均无臀中肌横截面积(CSA)指数(NO-GMedCI),对照组的NO张量松弛(TFL)CI,NO髂腰肌(IP)CI和最大臀肌(GMax)CI均低于有和没有FSSO的CroweIV型DDH。对照组的平均臀肌最小NOCI(NO-GMinCI)均高于有和没有FSSO的CroweIV型DDH。在新髋臼(APNA)的轴向位置方面,第1组和第2组之间存在显着差异(-0.03±8.5vs.5.27±6.33,p=0.004),新髋臼冠状位(CPNA)(33.39±10.65vs.53.70±12.27,p=0.000),手术腿长度差异(O-LLD)(14.18±15.14vs.24.44±15.80,p=0.001),O型臀肌最小值(GMin)长度(155.34±157.73vs.106.79±20,p=<0.01),和O-GMinCI(57.28±58.59vs.29.95±12.13,p=<0.01)。通过接收操作曲线分析确定的截止值如下:13.7mm,2.5mm,和41.4毫米的O-LLD,APNA,和CPNA,分别。
UNASSIGNED:FSSO与APNA关联,CPNA,O-LLD,O-GMin长度,O-GMinCI通过使用APNA的截止值,CPNA,和O-LLD,术前预测FSSO是可能的。由于这些参数,有可能降低手术的技术要求。
UNASSIGNED: Muscle and bone morphometry may be potent indicators for predicting femoral subtrochanteric shortening osteotomy (FSSO). We aimed to investigate muscular and bony factors that may be predictive of FSSO.
UNASSIGNED: Patients with unilateral Crowe type 4 developmental dysplasia of the hip (DDH) who underwent unilateral total hip arthroplasty (THA) without (Group 1, 31 patients) and with FSSO (Group 2, 39 patients) were included. Sixty healthy hips (Group 3) were selected as the control group. Several muscular and bony parameters were measured on the operative (O) and non-operative (NO) hips on radiographs and computed tomography (CT) images.
UNASSIGNED: The mean NO gluteus medius cross-sectional area (CSA) index (NO-GMed CI), NO tensor fasia lata (TFL) CI, NO iliopsoas (IP) CI, and NO gluteus maximus (GMax) CI for the control group were lower than those for both Crowe type IV DDH with and without FSSO. The mean NO gluteus minimus CI (NO-GMin CI) for the control group were higher than those for both Crowe type IV DDH with and without FSSO. There was significant difference between Groups 1 and 2 regarding axial position of neo-acetabulum (APNA) (- 0.03 ± 8.5 vs. 5.27 ± 6.33, p = 0.004), coronal position of neo-acetabulum (CPNA) (33.39 ± 10.65 vs. 53.70 ± 12.27, p = 0.000), operative leg length discrepancy (O-LLD) (14.18 ± 15.14 vs. 24.44 ± 15.80, p = 0.001), O-gluteus minimus (GMin) length (155.34 ± 157.73 vs. 106.79 ± 20, p = < 0.01), and O-GMin CI (57.28 ± 58.59 vs. 29.95 ± 12.13, p = < 0.01). The cutoff values determined by the receiving operating curve analyses were as follows: 13.7 mm, 2.5 mm, and 41.4 mm for O-LLD, APNA, and CPNA, respectively.
UNASSIGNED: FSSO is associated with APNA, CPNA, O-LLD, O-GMin length, and O-GMin CI. By using cutoff values of APNA, CPNA, and O-LLD, predicting FSSO preoperatively is possible. Owing to these parameters, it may be possible to lower the technically demanding level of surgery.
