Chinese Journal of Orthopaedic Trauma 2016;18(5):401-406
Objective To compare the lateral decubitus and supine position in the treatment of femoral intertrochanteric fractures with femoral proximal nail antirotation (PFNA).Methods A retrospective analysis was performed of the 85 patients with intertrochanteric fracture who had been treated at our hospital between September 2013 and September 2014.They were 24 men and 61 women,28 to 99 years of age (average,78.5 years).By Evans-Jensen classification,one case was type Ⅰ,15 cases were type Ⅱ,40 type Ⅲ,23 type Ⅳ,and 6 type Ⅴ.All the patients were treated with internal fixation with PFNA.Lateral decubitus position was adopted in 45 cases and supine position in 40.The 2 groups were compared in terms of operation time,intraoperative bleeding volume,difference between preoperative and postoperative hemoglobin values,tip-apex distance (TAD),calcar tip-apex distance (Cal-TAD),fracture healing time,and Harris score of the hip joint.Results The 85 patients were followed up for 9 to 21 months (average,13.6 months).Both 2 groups obtained fracture healing,with no screw cut-out.The lateral decubitus group had significantly less operation time (60.3 ± 17.5 min) and intraoperative bleeding volume (70.8 ± 37.8 mL) than the supine position group (72.7 ± 19.7 min and 90.3 ± 20.9 mL,respectively) (P < 0.05).The former also had a significantly smaller difference between preoperative and postoperative hemoglobin values (24.1 ± 5.7 g/L) than the latter (28.2 ± 8.5 g/L) (P < 0.05).There were no significant differences between the 2 groups in TAD,Cal-TAD,fracture healing time (3.7 ± 0.9 months versus 3.7 ± 1.0 months),or Harris hip score (73.4 ± 10.7 versus 75.5 ± 9.5) (P > 0.05).Conclusion In the treatment of femoral intertrochanteric fractures with PFNA,lateral decubitus position may be associated with shorter operation time and less intraoperative blood loss compared with supine position.

Objective To discuss the principle and the value of pereutanous microwave ablation for benign focal liver lesions. Methods Fourteen patients with 15 benign focal liver lesions received percutanous microwave ablation with 15G cool-tip microwave antenna. The maximum diameter of lesion was (26.2±13.6)mm (10 - 57 mm). Results Treatment sessions and total treatment time for single lesion were 1.4±0. 5 (1- 2) and (837±574)s (300- 2057 s). Follow-up range was 1- 35 months (median 6 months). The hepatic lesions were covered by coagulation necrosis region of ablation completely in all cases on contrast-enhanced at 1 month after ablation. The area of coagulation necrosis of ablation decreased on follow-up imaging in patients with more than 3 months follow-up. No complications happened in all cases. Side effects include pain (12/14) and fever (8/14) lasting I -9 days. The increase of serum transaminase decreased to normal at 1 week after ablation. Conclusions Percutanous microwave ablation has the merit of safety,minimal invasion, good ablation result and low incidence of side effect. Under the precondition of eareful choice of indication,pereutanous microwave ablation can be a selective treatment method for benign focal liver lesions.
