RESUMO
Objective:To compare the clinical efficacy of ultrasound-guided closed reduction and bare-handed reduction on pediatric distal radius fractures.Methods:Clinical data of 118 consecutive pediatric patients with distal radius fracture treated in the Wuhan Children′s Hospital, Tongji Medical College, Huazhong University of Science & Technology from April 2018 to August 2019 were retrospectively analyzed.Patients treated with bare-handed reduction and ultrasound-guided closed reduction were respectively classified into group Ⅰ (58 cases) and group Ⅱ (60 cases). Baseline characteristics, treatment duration, out-patient treatment cost, postoperative pain and the modified Mayo wrist function score during the follow-up visits between groups were compared by the t test.The success rate of initial reduction, reduction times, hospitalization rate and complication between 2 groups were compared by the Chi- square test.The number of postoperative imaging scans between 2 groups was compared by the Mann- Whitney U test. Results:There were no significant differences in out-patient treatment cost and hospitalization rate between 2 groups (all P>0.05). There were significant differences in the length of stay [ (166.2±54.8) min vs.(142.6±49.2) min], success rate of initial reductions [72.4%(42/58 cases ) vs.88.3%(53/60 cases)], incidence of repeated reductions (27.6% vs.1.7%) and the incidence of postoperative repeated imaging scans (20.7% vs.1.7%) between groupⅠ and group Ⅱ (all P<0.05). A total of 104 patients (88.1%) were successfully treated with closed reduction and followed up, with a rate of success reductions.Among them, success rate of closed reduction in group Ⅰ and Ⅱ were 86.2% and 90.0%, respectively.The mean time of fracture healing was 43 (34-56) days.There were no significant differences in fracture healing time and pain score between 2 groups(all P>0.05). The modified Mayo wrist score was significantly lower in group Ⅰ than that of group Ⅱ[(97.3±4.1) points vs.(98.8±2.9) points, P<0.05]. Seven patients in group Ⅰ suffered fracture re-displacement, including 6 cases within 1 case week and 1 within 2 weeks, and 4 cases admitted to the surgical ward for further management.Five patients in group Ⅱ had re-displacement within 1 week of plaster fixation, of which 2 cases admitted to the surgical ward for further management, which was comparable between groups( P>0.05). Conclusions:Both ultrasound-guided closed reduction and bare-handed reduction are effective on the treatment of pediatric distal radius fractures, showing low incidence of complications and satisfactory functional results.Owing to its higher success rate of initial reduction, lower frequency of postoperative ra-diography and shorter length of stay, ultrasound-guided closed reduction should be recommended.
RESUMO
Objective:To investigate the curative effect of Doppler ultrasound-guided management of vascular injury of Gartland type Ⅲ supracondylar fractures of humerus in children.Methods:A prospective study on 18 children with vascular complications of pulseless Gartland type Ⅲ supracondylar humeral fracture who were admitted at Department of Pediatric Orthopedic Surgery, Wuhan Children′s Hospital from March 2017 to March 2018 was conducted.Among these children, 12 were male and 6 were female, with the age of 2.1-8.6 years (mean 4.4 years old), and 10 cases were injured on the left and 8 cases on the right.All patients were satisfied with closed reduction and internal fixation within 24 hours after injury.Before the operation, Doppler ultrasound was performed to determine the shape of brachial artery and it relationship with fracture.During reduction, Doppler ultrasound was used to assess brachial pulse and blood perfusion.Then, the brachial artery was assessed by palpable radial pulse and peripheral blood supply, and elbow joint function was evaluated with Mayo Elbow Performance Score and Flynn criteria.Results:Eighteen patients were followed up for 6 to 12 months (average 9 months) after operation.Before reduction, radial pulse disappeared and peripheral blood supply was good in 18 cases.Preoperative Doppler ultrasonography showed that the brachial artery was located in front of the proximal humerus fracture fragment.A proximal stream of the brachial artery was identified, but the distal blood vessels were compressed by the fragment.A stream of radial artery was identified in 5 patients with Doppler, and no stream was identified in 13 patients.After reduction, the peripheral blood supply of all the affected limbs was good, among which the peripheral blood supply, 1 case returned to normal after 5 minutes waiting.Specifically the palpable radial pulse was immediately restored in 14 patients.The palpable radial pulse did not restore but the peripheral blood supply was good in 4 cases.Intraoperative ultrasonography showed that brachial artery blood flow was good, and palpable radial pulse was restored between 3 to 5 weeks later.In patients with at average sixteen-week neurological follow-up, 5 patients had complete resolution of nerve palsy.No complications such as forearm compartment syndrome and elbow joint dysfunction occurred.Functional outcome as measured by Flynn criteria was excellent in 12 patients, good in 6 patients, the excellent and good rate was 100%.Functional outcome as measured by Mayo Elbow Performance Score was excellent in 17 patients, good in one patient, the excellent and good rate was 100%.Conclusion:Ultrasound-guided is a safe and reliable option to treat pulseless Gartland type Ⅲ supracondylar humeral fracture.
RESUMO
Objective To investigate the effect of suction assisted closure (SAC) in treatment of children's leukemia with refractory ulcers.Methods The clinical data of 15 children who had leukemia associated with refractory ulcers from January 2013 to April 2017 in Department of Orthopedics,Wuhan Children's Hospital,Tongji Medical College of Huazhong University of Science & Technology were retrospectively analyzed.There were 8 males and 7 females,among whom 9 cases were acute non-lymphocytic leukemia and 6 cases were acute lymphoblastic leukemia.Patient's ages ranged from 2 to 9 years old with the mean age of 6.2 years.There were 5 cases of refractory ulcers located in the medial side of thigh and 4 cases in the perineum and around anus,3 cases in the ankle,2 cases in the crus and 1 case in the lateral side of thigh.The refractory ulceration area varied from 2 cm × 3 cm-7 cm × 5 cm,and the depth varied from 0.6-1.8 cm.All the 15 cases were cultured with secretions,including 7 cases of Staphylococcus aureus,4 cases of Escherichia coli,2 cases of Klebsiella pneumoniae,1 case of Pseudomonas aeruginosa,and 1 case with no bacteria detected.These children were transferred from Department of Hematology to Department of Orthopedics when there was no improvement in conventional therapy with the average treatment of 26 d (11-36 d).All of these children underwent SAC after thorough debridement.Secondary suturing of ulcers closure was performed or skin transplantation according to the recovery condition of ulcers.Results All the 15 patients of refractory ulcers achieved fresh granulation tissue after SAC treatment.Ten of them who had refractory ulcers could be sutured directly after once SAC treatment,and 5 cases who had refractory ulcers underwent SAC treatment again,in which 3 cases could be sutured directly,and the other 2 cases needed to reduce the wound area and autologous skin graft.All of these patients had refractory ulcers healed after SAC treatment,without any local or systemic complications.Conclusions SAC can bring the deep refractory ulcers into full drainage,protect the refractory ulcers against contamination,stimulate the growth of granulation tissue.SAC is a simple and effective method in treatment of children's leukemia with refractory ulcers.
