Objective To compare dynamic hip screw (DHS),InterTan and proximal femoral nail antirotation-Ⅱ (PFNA-Ⅱ) in the treatment of femoral intertrochanteric fracture in terms of their effects on postoperative hidden blood loss (HBL) and deep venous thrombosis (DVT).Methods We retrospectively analyzed the 133 patients with femoral intertrochanteric fracture who had been treated in our hospital from November 2011 to November 2015.Of them,42 received DHS treatment,including 22 males and 20 females;43 underwent InterTan fixation,including 21 males and 22 females;48 had PFNA-]Ⅱtreatment,including 25 males and 23 females.At preoperation,1,3 and 7 days postoperation,all of them had tests of hemoglobin (Hb),hematocrit value (Hct),blood platelet (PLT),thrombin time (TT),activated partial thromboplastin time (APTT),prothrombin time (PT),human fibrinogen (FIB) and D-dimer.DVT was detected using color Doppler ultrasound at 7 days postoperation.Results At 1,3 and 7 days postoperation,the DHS patients had the smallest values of Hb,Hct,TT,PT and APTT while the PFNA-Ⅱ patients the largest.The DHS patients had the largest values of intraoperative bleeding,PLT,FIB and D-dimer while the PFNA-Ⅱ patients the smallest.There were significant differences between the 3 groups in all the indexes (P ＜ 0.05) except in TT at 7 days postoperation and APTT at 1 and 7 days postoperation between the InterTan and PFNA-Ⅱ groups (P ＞ 0.05).The incidence of DVT in the InterTan group (2.3％,1/43) and in the PFNA-Ⅱ group (0) was significantly lower than in the DHS group(7.1％,3/42) (P ＜ 0.05).Conclusion In the treatment of femoral intertrochanteric fracture,PFNA-Ⅱ may be superior to InterTan and DHS in reducing postoperative HBL and control of DVT.

Objective To explore the application effect of personalized lateral decubitus pillow for patients with cervical spine surgery. Methods A totals of 106 patients after cervical spine surgery were recruited and randomly divided into control group (48 cases) and experimental group (58 cases). Patients in the control group used the common pillow when patients lay lateral position-the height of pillow equal to shoulder cheekbone breadth, while experimental group used the personalized lateral decubitus pillow which supported suspended occipitalis and the height of pillow adjusted by individual. The comfort score, incision pain score and last time for lateral position of all patients were compared. Results The comfort score of the experimental group was significantly higher than that of the control group during the first day, second day and the third day after surgery [(66. 3 ± 4. 8) vs (63. 4 ± 3. 5), (68. 4 ± 5. 3) vs (65. 1 ± 4. 6), (71. 3 ± 4. 8) vs (68. 3 ± 4. 4);t=3. 461,3. 473,3. 270, respectively; P <0. 05]. The incision pain score of the experimental group was significantly lower than that of the control group during the first day, second day and the third day after surgery [(5.09±1.33) vs(5.88±1.29),(4.78±1.30) vs(5.52±1.09),(4.33±1.13) vs(5.06±1.06);t=3. 127,3. 157,3. 427, respectively;P<0. 05]. The last time of the experimental group for lateral position were longer than that of control group [(88. 6 ± 15. 2) min vs (79. 3 ± 14. 1) min; t = -3. 239,P =0. 002]. Conclusions It can increase the comfort score, extend the last time for lateral position and lessen incision pain to use the individuation lateral position pillow for patients after cervical spine surgery.
