RESUMO
Objective:To compare the early outcome of proximal femoral nail antirotation (PFNA) and bipolar hemiarthroplasty in treatment of intertrochanteric fractures in elderly patients aged 90 years or more.Methods:A retrospective case-control study was conducted to analyze the clinical data of 43 elderly patients aged 90 years or more with intertrochanteric fractures admitted to Henan Provincial People's Hospital from January 2017 to June 2018. There were 12 males and 31 females, aged 90-102 years [(92.3±2.5)years]. A total of 31 patients were treated by PFNA (PFNA group) and 12 patients by bipolar hemiarthroplasty (hemiarthroplasty group). Comparisons were made between the two groups in terms of operation time, intraoperative blood loss, time of weight bearing after operation, rate of blood transfusion, incidence of complications 2 weeks and 3 months after operation, Harris score 12 months after operation and mortality 12 months after operation.Results:All patients were followed up for 1-30 months [(19.1±9.8)months] in PFNA group and for 0.5-29 months [(18.6±10.6)months] in hemiarthroplasty group. Operative time was (95.8±31.0)minutes in PFNA group, shorter than (128.8±40.5)minutes in hemiarthroplasty group ( P<0.05). Intraoperative blood loss was (71.3±25.7)ml in PFNA group and (212.5±113.1)ml in hemiarthroplasty group ( P<0.05). Time of weight bearing after operation was (43.9±31.9)days in PFNA group, longer than (5.9±2.8)days in hemiarthroplasty group ( P<0.05). The perioperative blood transfusion rate in PFNA group (29%) was less than hemiarthroplasty group (75%) ( P<0.05). Incidence of complications 2 weeks after operation was similar between PFNA group (23%) and hemiarthroplasty group (42%) ( P>0.05). Incidence of complications 3 months after operation in PFNA group was 26%, similar with 42% in hemiarthroplasty group ( P>0.05). Harris score 12 months after operation in PFNA group was (56.3±32.3)points, comparable to (59.3±36.7)points in hemiarthroplasty group ( P>0.05). Mortality rate 12 months after operation was 19% in PFNA group and 25% in hemiarthroplasty group ( P>0.05). Conclusion:For intertrochanteric fractures in elderly patients aged 90 years or more, PFNA and bipolar hemiarthroplasty are both effective treatments, but PFNA may be a better choice with shorter operation time and less intraoperative blood loss.
RESUMO
Objective To investigate the effect of our self-developed acetabular reduction clamp in the treatment of fractures of acetabular posterior column.Methods The data were retrospectively analyzed of the 32 patients who had been treated for acetabular posterior column fractures using our self-developed acetabular reduction clamp at Department of Minimally Invasive Surgery,Zhengzhou Orthopaedics Hospital from August 2016 to June 2018.They were 17 males and 15 females,aged from 18 to 62 years (average,41.3 years).According to the Letournel-Judet classification,there were 9 simple posterior column fractures,14 posterior column plus posterior wall fractures,4 T-shaped fractures and 5 double column fractures.The Kocher-Langenbeck (K-L) incision was used for simple posterior column and posterior column plus posterior wall fractures,and the K-L combined with anterior ilioinguinal approach for T-shaped and double column fractures.The displaced posterior column fracture was repositioned with our novel reduction clamp before pelvic reconstruction plate was used for fixation.The quality of fracture reduction,fracture union time,complications and hip function score at the last follow-up were recorded.Results This series of 32 patients were followed up for 7 to 20 months (average,12.9 months).According to the Matta scores for fracture reduction at the last follow-up,15 cases were excellent,16 good and one poor,yielding an excellent and good rate of 96.9％.The fracture union time ranged from 3 to 6 months (average,4.7 months).According to the modified Merle d'Aubign scores at the last follow-up,hip function was excellent in 18 cases,good in 11 and fair in 3,yielding an excellent and good rate of 90.6％.Postoperative symptomatic distraction injury to the sciatic nerve appeared in 2 patients,postoperative wound lipid liquefaction developed in one and heterotopic ossification of Brooker grade Ⅱ was observed in 2 patients during follow-up.Conclusion In the treatment of acetabular posterior column fracture with open reduction and internal fixation with pelvic reconstruction plate through the K-L approach,our novel acetabular reduction clamp can be used safely and effectively to assist fracture reduction,leading to satisfactory results.
RESUMO
Laparoscopic cholecystectomy (LC) patients showed mild to moderate pain, non steroidal anti-inflammatory drugs (NSAIDS), opioids and antiepileptic drugs are used in routine treatment of postoperative pain in clinic. Although these drugs worked quickly, their adverse effects, such as drowsiness, post-operative nausea and vomiting (PONV), constipation and respiratory inhibition can lead to delayed discharge. Therefore, many researchers study the replacement treatment of postoperative pain. Pain after LC can be divided into superficial incision pain, deep visceral pain and shoulder referred pain. The species of drug are local anesthetics, steroid, tramadol and dexmedetomidine. There are 3 main types intraperitoneal administration time: before the establishment of pneumoperitoneum, at the time of pneumoperitoneum and immediately after removal of the gallbladder. Intraperitoneal administration is often applied to the fossa of gallbladder, liver diaphragm, liver and diaphragm gap or the sites near the hepatoduodenal ligament. The main methods of intraperitoneal administration are instillation, infiltration, spraying and flushing. Based on many studies, it is beneficial to use intraperitoneal administration in terms of pain reduction in the early stage after LC. The use of intraperitoneal administration could reduce the amount of analgesic and mitigate the associated complications.
