ABSTRACT
Objective:To explore the diagnosis and treatment of humeral medial epicondyle fracture combined with radial neck fracture in children and adolescents.Methods:The clinical data were retro-spectively analyzed of the 12 pediatric patients with fractures of the humeral medial epicondyle plus the radial neck who had been admitted from February 2015 to August 2021 to Department of Pediatric Orthopedics, The Second Hospital of Fuzhou. There were 6 males and 6 females, with an age of (11.1 ± 2.5) years. According to the Papavasiliou classification, the humeral medial epicondyle fractures were type Ⅱ in 7 cases, type Ⅲ in 2 cases and type Ⅳ in 3 cases; according to the Judet classification, the radial neck fractures were type Ⅰ in 3 cases, type Ⅱ in 4 cases and type Ⅲ in 5 cases. Two Judet-Ⅰ radial neck fractures were missed by X-ray exam-ination but diagnosed by CT examination. Of the humeral medial epicondylar fractures, 9 were treated by open reduction and hollow screwing and 3 by closed reduction and Kirschner wiring. Of the radial neck fractures, 8 were treated by closed reduction and elastic intramedullary nailing and 4 conservatively. Fracture healing was followed up by postoperative radiographs. At the last follow-up, the carrying angles were measured, Kim Elbow Function Score (KEPS) was used to evaluate the functional recovery of the injured limb, and related complications were recorded.Results:All the 12 patients were followed up for (40.0±25.6) months. Fractures headed after (6.3±1.2) weeks. At the last follow-up, the carrying angle was 15.5°±2.6° on the injured side and 14.7°±2.0° on the healthy side, showing no significant difference ( P>0.05); KEPS was (96.3±5.3) points on the injured side and (98.8±2.3) points on the healthy side, showing no significant difference either ( P>0.05). No incision infection, bone nonunion, elbow valgus, joint stiffness or other complications were found; the postoperative elbow stability recovered well. Conclusions:As the fracture of the humeral medial epicondyle combined with the radial neck fracture is a special type of injury of straightened elbow during valgus stress in children and adolescents, it is likely to be missed in diagnosis. The goal of treatment is good functional recovery by restoring the articular match and elbow stability.
ABSTRACT
Objective:To investigate the clinical results of Bouquet technique [multiple elastic stable intramedullary nails (ESIN)] in the treatment of unstable pediatric femoral shaft fractures.Methods:From August 2016 to October 2019, 25 pediatric patients (26 sides) with unstable femoral shaft fracture were treated with Bouquet technique at Department of Pediatric Orthopedics, The Second Fuzhou Hospital Affiliated to Xiamen University. They were 17 boys and 8 girls, with a mean age of 7.8 years at injury (from 5 to 11 years). Their body weight ranged from 23 kg to 62 kg, with an average of 36.3 kg. Long oblique fractures happened in 6 cases (6 sides) and comminuted fractures in 19 cases (20 sides). Ten cases (11 sides) were fixated with 3 ESINs (type 3A) and 15 cases (15 sides) with 4 ESINs (type 4A in 6 cases and type 2A+2B in 9 cases). The multiple ESINs were inserted from the medial and lateral cortex of the distal femur through the fracture sides until the head ends of the nails were distributed evenly at the proximal femur. Recorded were the fracture healing time, complications, fracture reduction quality and hip function at the last follow-up.Results:All the 25 patients were followed up for 18 to 27 months (mean, 22.4 months). Their fractures got united after 4 to 8 weeks (mean, 6.3 weeks). One case presented with femoral overgrowth of 1.1 cm and another case with nail tail irritation. Follow-ups revealed that none of the patients had such complications as incision infection, limited joint movement, nonunion or delayed fracture union. The limb alignment recovered well with no angulation, shortening or rotational deformity. At the last follow-up, according to the efficacy evaluation system for intramedullary nails by Flynn et al., the quality of reduction of femoral shaft fractures was assessed as excellent in 24 sides and as good in 2 sides, giving an excellent and good rate of 100% (26/26). According to the hip Harris scoring system, the hip function was assessed as excellent in all the 26 sides, giving an excellent rate of 100% (26/26).Conclusion:Bouquet technique is safe and effective in the treatment of unstable pediatric femoral shaft fractures, leading to fine clinical results.
ABSTRACT
Objective:To evaluate the ultrasonography-guided percutaneous leverage reduction in the treatment of pediatric radial neck fractures.Methods:From May 2016 to May 2018, 42 patients with Judet Ⅲ or Ⅳ radial neck fracture were treated at Department of Pediatric Orthopedics, The Second Hospital of Fuzhou. They were 15 boys and 27 girls, aged from 3 to 12 years. All of them were treated by percutaneous leverage reduction and Métaizeau technique. The operative procedures were guided by ultrasonography in 20 cases and by C-arm fluoroscopy in 22 cases. Postoperative evaluation was based on Métaizeau imaging criteria, Tibone and Stoltz functional criteria; complications such as radial nerve injury were recorded.Results:There were no statistically significant differences between the ultrasonography-guided group and the fluoroscopy-guided group in preoperative general data, showing comparability ( P>0.05). There were no significant differences between the 2 groups in terms of Métaizeau imaging, Tibone or Stoltz functional scores ( P>0.05). The frequency of fluoroscopy was (2.7±0.6) times for the ultrasonography group and (14.6±3.4) times for the fluoroscopy group while the operation time averaged (25.8±5.9) min for the former and (38.1±9.2) min for the latter, showing significant differences ( P<0.05). No postoperative complications were observed in the ultrasonography group while 4 cases of radial nerve injury in the fluoroscopy group, also showing significant difference between the 2 groups ( P< 0.05). Conclusion:Ultrasonography-guided percutaneous leverage reduction is a suitable surgical treatment of radial neck fracture in children, because it is simple, effective and safe.
