  • HINGED EXTERNAL FIXATOR WITH MINI-PLATE TO TREAT TERRIBLE TRIAD OF ELBOW

    Objective To investigate the effectiveness of hinged external fixator with mini-plate to treat terrible triad of the elbow. Methods Between August 2008 and June 2011, 11 patients with terrible triad of the elbow were treated with hinged external fixator combined with mini-plate. There were 9 males and 2 females, aged 22-56 years (mean, 34 years). The injuries were caused by falling from height in 8 cases and traffic accident in 3 cases. All patients were closed injury. The time from injury to operation varied from 8 hours to 7 days (mean, 3.7 days). According to Mason classification standard, all radial head fractures were type IV and complicated by posterior dislocation of the elbow; according to Regan-Morrey classification standard, ulna coronary process fractures were type I in 3 cases, type II in 3 cases, and type III in 5 cases. Results All the patients achieved primary healing of incision after operation and no nerve injury occurred. The patients were followed up 12-20 months (mean, 15 months). Two cases had screw channel infection after 12 weeks of operation, and 1 case had mild heterotopic ossification of the elbow after 4 months of operation. X-ray films showed that all fractures healed from 8 to 20 weeks (mean, 16 weeks). No recurrent dislocation or instability of the elbow occurred. At 12 months after operation, the elbow range of motion (ROM) were 120-145° (mean, 135°) in flexion, 0-25° (mean, 10°) in extension, 50-90° (mean, 70°) in pronation, and 50-80° (mean, 60°) in supination. According to Mayo elbow function evaluation standard, the results were excellent in 5 cases, good in 4 cases, and fair in 2 cases, with an excellent and good rate of 81.8%. Conclusion Hinged external fixator with mini-plate can enhance postoperative stability of the elbow. This therapy is beneficial to early functional exercise and obviously decrease the disability rate caused by complex damage on the elbow.

  • Clinical effect of anal fistula clip in treatment of anal fistula

    ObjectiveTo analyze the effect of anal fistula clip (AFC) in the treatment of anal fistula, and to evaluate its safety. MethodsA historical cohort study method was conducted. Eighty-three patients with glandular transsphincteric anal fistula in the Xuzhou Central Hospital from September 2018 to May 2021 were collected, of which 42 patients underwent the AFC treatment (AFC group), 41 patients underwent the endorectal advancement flap (ERAF) treatment (ERAF group). The operation time, intraoperative blood loss, visual analogue scale (VAS) score of anus pain on postoperative day 1, 3, and 7, wound healing time, Wexner incontinence score of anal function on postoperative month 6, and clinical efficacy (healing and failure) were compared between the two groups. ResultsThe operation was successfully completed in both groups. The operation time and intraoperative blood loss in the AFC group were shorter or less than those in the ERAF group (P<0.05). No complications such as internal opening infection and bleeding occurred in the two groups. There were no statistical differences in the VAS score of postoperative anus pain at all time point between the two groups (P>0.05). The median follow-up time was 22 months. There was no statistical difference in the wound healing time between the two groups (P>0.05). The Wexner score of anal function in the AFC group was lower than that in the ERAF group (P<0.05), and there was no statistical difference between after operation and before operation (Z=–1.751, P=0.089) in the AFC group, while that in the ERAF group after operation was higher than before operation (Z=–1.859, P=0.014). The healing rate had no statistical difference between the AFC group and ERAF group (85.7% versus 77.5%, χ2=0.925, P=0.336). Conclusion From the results of this study, the AFC is safe and effective in treatment of anal fistula, with the advantages of relatively simple operation, less bleeding during operation, lighter postoperative pain, and good protection of anal function.

  • Soft tissue balance technique by flexor pollicis longus tendon transfer for Wassel Ⅳ-D thumb duplication in children

    ObjectiveTo investigate the effectiveness of soft tissue balance technique by flexor pollicis longus (FPL) tendon transfer for Wassel Ⅳ-D thumb duplication in children. Methods A clinical data of 14 children with Wassel Ⅳ-D thumb duplication met the selection criteria between January 2017 and January 2021 was retrospectively analyzed. There were 5 boys and 9 girls with an average age of 21.6 months (range, 18-35 months). Ten cases were left hand deformity and 4 cases were right hand deformity. During operation, the radial thumb was excised, and the FPL tendon of the radial thumb was used to reconstruct the soft tissue balance of the ulnar thumb. Postoperative evaluation included the range of motion (ROM) of passive flexion and extension of the interphalangeal joint (IP) and metacarpophalangeal joint (MCP), the alignments of the IP and MCP, the percentage of the width of the nail plate and the circumference of the thumb at the level of the IP to contralateral thumb. Results All operations were completed successfully, and all incisions healed by first intention. The children were followed up 12-36 months (mean, 21.7 months). At last follow-up, the ROM of passive flexion and the deviation of the IP, and the deviation of the MCP significantly improved when compared with those before operation (P<0.05); the ROM of passive extension of the IP and the ROM of passive flexion of the MCP did not significantly improve when compared with those before operation (P>0.05). The ROMs of passive extension of the MCP were 0° before and after operation. The width of the nail plate was 76.6%±4.1% of the unaffected side, and the circumference of the thumb at the level of the IP was 92.0%±9.1% of the unaffected side. ConclusionThe soft tissue balance technique by FPL tendon trasfer can effectively correct the alignment of the Wassel Ⅳ-D thumb duplication in children, and maintain the correction effect effectively, but further follow-up and comprehensive evaluation are needed to investigate the long-term effectiveness.

  • Analysis of Risk Factors for Acute Kidney Injury after Aortic Arch Replacement Surgery

    Abstract: Objective To determine the risk factors for acute kidney injury (AKI) after thoracic aortic arch replacement surgery under deep hypothermic circulatory arrest (DHCA). Methods We retrospectively analyzed the clinical data of 139 patients who underwent thoracic aortic arch replacement surgery under DHCA between January 2004 and December 2008 in Beijing Anzhen Hospital Affiliated to Capital University of Medical Sciences. The patients were divided into two gro-ups according to whether AKI occurred after thoracic aortic arch replacement surgery. In the AKI gro-up (n=48), there were 39 males and 9 females with an age of 57.67±9.56 years. In the normal renal function gro-up (n=91), there were 69 males and 22 females with an age of 41.30±13.37 years. We observed the clinical data of the patients in both gro-ups, including left ventricular ejecting fraction (LVEF) before operation, diameter of the left ventricle, diameter of the ascending aorta, renal function, cardiopulmonary bypass time, aortic crossclamp time, and DHCA time. The risk factors for AKI and death after operation were evaluated by univariate analysis and stepwise logistic regression analysis. Results Among all the patients, AKI occurred in 48 (34.53%), 17 (12.23%) of whom underwent continuous renal replacement therapy (CRRT). Respiratory failure occurred in 27 patients (19.42%). Twentynine patients (20.86%) had cerebral complications, including temporary cerebral dysfunction in 26 patients and permanent cerebral dysfunction in 3 patients. In all the patients, 14 (10.07%) died, including 4 patients of heart failure, 9 patients of multiple organ failure, and 1 patient of cerebral infarction. There were 3 (3.30%)deaths in the normal renal function gro-up and 11 (22.92%) deaths in the AKI gro-up with a significant difference of mortality rate between the two gro-ups (P=0.011). A total of 118 patients were followed -up and 7 were lost. The follow-up time was from 5 to 56 months with an average time of 42 months. During the follow-up period, 7 patients died, including 3 patients of heart failure, 2 patients of cerebral apoplexy, and 2 patients of unknown reasons. The logistic regression analysis revealed that creatinine level was greater than 13260 μmol/L before operation (OR=1.042, P=0.021) and respiratory failure (OR=2.057, P=0.002) were independent determinants for AKI after the operation. Conclusion AKI is the most common complication of thoracic aortic arch replacement surgery under DHCA, and is the risk factor of mortality after the surgery. It is important to enhance perioperative protection of the renal function.
