ABSTRACT
Objective:To compare the short-term efficacy between our self-designed intelligent robot-assisted minimally invasive reduction system and conventional freehand reduction assisted by fluoroscopy in the treatment of unstable pelvic fractures by robot or fluoroscopy-assisted internal fixation with percutaneous screws.Methods:A prospective randomized controlled trial was conducted to include eligible 35 patients with unstable pelvic fracture who were admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from December 2021 to October 2022. They were randomized into 2 groups. The observation group[17 cases, 10 males and 7 females with an age of (44.0±17.4) years] was treated with robot-assisted minimally invasive reduction, followed by robot-assisted or fluoroscopic internal fixation with percutaneous screws; the control group[18 cases, 12 males and 6 females with an age of (38.8±15.0) years] was treated with freehand reduction assisted by fluoroscopy, followed by robot-assisted or fluoroscopic internal fixation with percutaneous screws. The 2 groups were compared in terms of operation time, intraoperative bleeding, successful reduction, reduction quality, incidence of surgical complications and postoperative functional scores.Results:The 2 groups were comparable because there were no significant differences in the preoperative general data between them ( P>0.05). The intraoperative fluoroscopy frequency[(32.4±17.5) times] and fluoroscopy time [(19.8±10.4) s] in the observation group were significantly lower or shorter than those in the control group [(60.8±26.6) times and (38.2±16.1) s], and the rate of successful reduction in the observation group was 100.0% (17/17), significantly higher than that in the control group[72.2% (13/18)] ( P<0.05). There was no significant difference between the 2 groups in intraoperative bleeding, operation time, reduction error, excellent and good rate of reduction after operation by Matta scoring, or Majeed functional score at 12 weeks after operation ( P>0.05). Conclusion:In the treatment of unstable pelvic fractures, since our self-designed intelligent robot-assisted minimally invasive reduction system can plan autonomously the reduction paths and accomplish minimally invasive reduction of the fracture with 3D images real-time monitoring, it is advantageous over conventional reduction methods in a higher success rate and less radiation exposure.
ABSTRACT
Objective:To compare the short-term efficacy between femoral neck system (FNS) and cannulated compression screws (CCS) in the treatment of femoral neck fractures in young and middle-aged patients.Methods:A retrospective study was performed of the 29 young and middle-aged patients with femoral neck fracture who had been treated with FNS at Department of Orthopaedics and Traumatology, Beijing Jishuitan Hospital from January 2020 to December 2020. A control group of another 29 patients with femoral neck fracture was selected who had been treated with CCS but matched in gender, age, and body mass index. In the CCS group, there were 14 males and 15 females with an age of (48.2±12.3) years; in the FNS group, there were 14 males and 15 females with an age of (48.2±12.0) years. The fracture reduction quality, operation time, intraoperative blood loss, and femoral neck shortening, hip joint function, Barthel index and health survey 12-item short form (SF-12) score at the last follow-up and complications during follow-up were compared between the 2 groups.Results:No significant difference was found in the preoperative general data or follow-up time between the 2 groups, showing comparability ( P>0.05). The intraoperative blood loss in the CCS group [20 (10, 50) mL] was significantly less than that in the FNS group [50 (20, 50) mL], and the femoral neck shortening at the last follow-up in the CCS group (grade 1 in 5 cases; grade 2 in 18 cases and grade 3 in 6 cases) was significantly worse than that in the FNS group (grade 1 in 21 cases, grade 2 in 6 cases and grade 3 in 2 cases) ( P<0.05). No significant difference was found regarding fracture reduction quality, operation time, complications during follow-up, or Merle D'Aubigne Postel score, Barthel index or SF-12 score at the last follow-up ( P>0.05). Conclusions:In the treatment of femoral neck fractures in young and middle-aged patients, both FNS and CCS are good options for internal fixation. However, FNS can reduce the severity of femoral neck shortening and maintain the length of femoral neck better than CCS.
ABSTRACT
ObjectiveTo evaluate the efficacy and safety of a perioperative rehabilitation clinical pathway of acetabular fracture in light of orthopedics rehabilitation team approach. MethodsA prospective randomized control trial was conducted in 82 patients with acetabular fractures who had been admitted from the Emergency Department of Orthopaedic Trauma, Beijing Jishuitan Hospital from June, 2019 to January, 2021. The patients were randomly divided into control group (n = 41) and intervention group (n = 41). The control group was managed routinely, while the intervention group received the rehabilitation clinical pathway, for 24 weeks. The Visual Analogue Score (VAS) of pain, the Barthel Index (BI) and Majeed Pelvic Score were compared. ResultsFinally, 76 patients completed the trial. There was no statistical difference in VAS score between two groups in all periods (|Z| < 1.926, P > 0.05). The BI score was higher in the intervention group than in the control group at discharge, two weeks, six weeks and twelve weeks after operation (|Z| > 2.121, P < 0.05); and no significant difference was found before operation and 24 weeks after operation (|Z| < 1.862, P > 0.05). Majeed Pelvic Score was higher in the intervention group than in the control group two weeks, six weeks, twelve weeks and 24 weeks after operation (|Z| > 2.428, P < 0.05). Six, twelve and 24 weeks after operation, the excellent rate of Majeed Pelvic Score was higher in the intervention group than in the control group (χ2 > 6.136, P < 0.05). ConclusionIn comparison with traditional protocol in acetabular fracture, the perioperative rehabilitation clinical pathway was proved effective and of great safety in the light of the integration of orthopedics and rehabilitation mode for improving the function and activities of daily living of patients.
ABSTRACT
Objective:To evaluate the efficacy and safety of perioperative rehabilitation approaches based on the concept of Enhanced Recovery After Surgery (ERAS) for pelvic fractures.Methods:A prospective randomized control trial was conducted to include 114 emergency patients who had been admitted to Department of Orthopaedic Trauma, Beijing Jishuitan Hospital for surgical treatment of pelvic fractures from June 2019 to December 2020. Of them, 57 were assigned into an intervention group according to a random digits table. They were 42 males and 15 females, aged from 18 to 77 years and subjected to management of pelvic fractures with tentative perioperative ERAS approaches which were adjusted at different stages. The other random 57 patients were assigned into a control group. They were 40 males and 17 females, aged from 17 to 70 years and subjected to management of pelvic fractures with conventional rehabilitation approaches which included postoperative in-hospital consultation and guidance by rehabilitation physicians. The 2 groups were compared in terms of Majeed pelvis scores and Barthel indexes at postoperative 2, 6, 12 and 24 weeks, and visual analogue scale (VAS) pain scores and SF36 scores at postoperative 12 and 24 weeks.Results:A total of 105 patients (55 in the intervention group and 50 in the control group) were completely followed up for 151 to 254 d (mean, 177 d). The 2 groups were comparable due to no significant difference between them in the preoperative general data ( P>0.05). The Majeed scores (44±13, 67±16, 86±14 and 98±7) and Barthel indexes (57±13, 79±16, 95±8 and 100±2) at postoperative 2, 6, 12 and 24 weeks in the intervention group were significantly higher than those in the control group [(35±16, 51±16, 73±14 and 91±12) and (45±19, 67±18, 86±12 and 98±4)] (all P<0.05). At postoperative 12 and 24 weeks, the SF-36 scores (129±15 and 141±6) in the intervention group were significantly higher than those in the control group (114±15 and 131±12) ( P<0.05). There was no significant difference in the pain degree between the 2 groups ( P>0.05). Conclusion:In management of pelvic fractures, compared with conventional perioperative rehabilitation approaches, the perioperative ERAS rehabilitation approaches may improve early functional outcomes and thus help the patients restore their activities of daily living earlier.
ABSTRACT
@#Objective To evaluate the effect of rehabilitation nursing with movement getting out of bed in early period after operation on the patients undergone the total hip replacement (THR).Methods The rehabilitation nursing was performed to 47 patients undergone THR including movement getting out of bed in early period; prepared sufficiently pre-operatively (evaluation and rehabilitation training); avoided the complications post-operatively; monitored the vital signs; trained standardizely; relieved pain sufficiently; took off the tubing as early as possible; rehabilitated with the walking aid.Results None had DVT, dislocation, fracture around the prosthesis, infections, death etc, all patients got out of bed in the 1st day after operation, the average time in hospital was 19 days, and the average Harris scores were 54.26, 62.55, 73.58, 91.17 and 93.35 at pre-operation, and in 14th day, 1st month, 3rd month and 6th month post-operation respectively.Conclusion Rehabilitation nursing with early movement getting out of bed to exercise after THR operation can promote the recovery of the hip function, reduce the complications, shorten the hospital stay.
ABSTRACT
Objective To discuss the clinical value of retroperitoneal laparoscopic simple nephrectomy. Methods Retroperitoneal laparoscopic simple nephrectomy was performed in 6 patients, including 5 cases of severe hydronephrosis with non-functioning kidney resulted from ureteral calculi and 1 case of renal tuberculosis. The operation was conducted via retroperitoneal approach. After the upper ureter and the renal pedicle were exposed, the renal artery and vein were clipped and severed. The renal pedicle was occluded only with titanium clips before the removal of the kidney. Results All the operations were performed successfully without complications. The operation time was 130~220 min (mean, 150 min) and the intraoperative blood loss, 80~150 ml (mean, 120 ml). The postoperative hospital stay ranged 5~7 days. Follow-ups for 3 months in the 5 patients with ureterolithiasis revealed normal renal functions. The patient with renal tuberculosis was given anti-tuberculosis therapy and followed for 6 months. No recurrence was seen and the patient’s serum creatinine level was 120 ?mol/L, which was slightly higher than the normal. Conclusions Retroperitoneal laparoscopic simple nephrectomy has advantages of minimal invasion, short hospital stay and rapid recovery. The procedure should be regarded as the “golden standard” for simple nephrectomy.
