ABSTRACT
Objective:To explore the clinical characteristics and treatment of a head-neck separation type of Monteggia equivalent fractures in children.Methods:From March 2016 to February 2019, 12 children sought medical attention at Pediatric Orthopedic Hospital, Honghui Hospital Affiliated to Xi'an Jiaotong University for a head-neck separation type of Monteggia equivalent fractures. They were 8 boys and 4 girls, aged from 3 to 14 years (average, 8.3 years). All cases were treated with closed reduction, deformity correction and plaster fixation at emergency department after X-ray examination. In line with the treatment principles for Monteggia fractures, after the ulnar length was first restored and stabilized, a proper fixation method was chosen according to the location and type of the ulnar fracture, followed by treatment of the radial neck fracture. The fracture union and complications were evaluated according to the X-ray films after operation, and the therapeutic efficacy was evaluated according to the Mayo elbow performance score (MEPS) at the final follow-up.Results:The head-neck separation type of Monteggia equivalent fractures in children was characterized by a fracture of ulnar diaphysis or metaphysis and a fracture of the radial neck with complete separation of the head and neck, a longitudinal axis of the radius off the capitellum center at the distal fracture end but normal proximal humeroradial relationship. The fractures were classified into 2 types depending on the angulation direction of the ulnar fracture and the direction of distal displacement of the radial neck fracture: 7 cases belonged to the extension-valgus type and 5 cases to the flexion-varus type. The 12 patients were followed up for 8 to 38 months (average, 16.0 months). Of the ulnar fractures, one was treated with closed reduction and Kirschner wire fixation, 4 with elastic intramedullary nail fixation, 5 with plate fixation, one untreated, and one with manual reduction only. Of the radial neck fractures, 11 were treated with closed reduction and elastic intramedullary nail fixation, and one with open reduction and K-wires fixation. All fractures got united after 8 to 12 weeks (mean, 9.6 weeks). The time for removal of internal fixation ranged from 12 to 50 weeks (mean, 31.2 weeks). Avascular necrosis occurred in one case and bulk formation of proximal metaphysis in another. By the MEPS at the final follow-up, the therapeutic efficacy was excellent in 10 cases, good in one and fair in one.Conclusions:The head-neck separation type of Monteggia equivalent fractures in children is different from common Monteggia fractures or radial neck fractures, because its clinical manifestations are characterized by a fracture of ulnar diaphysis or metaphysis and a fracture of the radial neck with complete separation of the head and neck, a longitudinal axis of the radius off the capitellum center at the distal fracture end but normal proximal humeroradial relationship. The treatment options for ulnar fractures include closed reduction with Kirschner wire fixation, elastic intramedullary nailing, open reduction and bone plate fixation or no fixation, while radial neck fractures are mostly treated by closed reduction and elastic intramedullary nailing. Early functional exercise can lead to satisfactory clinical outcomes.
ABSTRACT
Objective:To investigate the efficacy of intramedullary plus extramedullary fixation in the treatment of fractures of distal radial diametaphyseal transition zone in children.Methods:The data were retrospectively analyzed of the 49 children who had been admitted to Pediatric Orthopedic Hospital, Honghui Hospital Affiliated to Xi'an Jiaotong University from July 2018 to April 2020 for fractures of distal radial diametaphyseal transition zone. There were 30 males and 19 females; 21 left sides, 27 right sides, and one case of bilateral sides. In the operation, an elastic intramedullary nail or Kirschner wire was used for intramedullary fixation while another Kirschner wire was used to fix the cortex at the distal and proximal ends of the fracture. The ranges of wrist motion and Disabilities of the Arm, Shoulder and Hand (DASH) scores at 1 and 9 months after operation were recorded and compared; the incidence of postoperative complications was also recorded.Results:The operation time for the 49 children averaged 45.0 min (from 39 to 51 min). The patients were followed up for 6 to 36 months (mean, 18.6 months). The fracture union time averaged 8.6 weeks (from 6.8 to 10.4 weeks). Needle tract infection developed in one case but the wound was healed after removal of the K-wire after callus formation and oral use of antibiotics for 3 days. Another case reported skin irritation the symptoms of which disappeared after the child reduced activities. The ranges of pronation, supination, flexion and extension of the wrist and DASH score were 47.9°±2.5°, 45.5°±3.0°, 51.2°±1.6°, 53.4°±1.7° and (36.7±4.5) points at one month after operation while they were 85.6°±3.1°, 87.6°±2.1°, 88.8°±2.0°, 88.0°±1.2° and (23.2±8.6) points at 9 months after operation. There were statistically significant differences in the above indexes between one and 9 months after operation ( P<0.05). Conclusion:In the treatment of fractures of distal radial diametaphyseal transition zone in children, intramedullary plus extramedullary fixation is simple in surgical techniques, easily repeatable, slightly invasive, and reliable in fixation.
ABSTRACT
Objective:To evaluate the treatment of nonunion of lateral humeral condyle complicated with cubitus valgus with primary fixation in situ and secondary supracondylar varus osteotomy.Methods:A retrospective analysis was made of the 8 children who had been treated for nonunion of lateral humeral condyle complicated with cubitus valgus at Department of Pediatric Orthopedics, Honghui Hospital from January 2016 to March 2018. They were 5 boys and 3 girls with 5 left and 3 right sides involved. Their age at injury ranged from 6 to 14 years (average, 10 years) and the duration from injury to operation from 2 to 6 years (average, 4 years). At the primary stage, the fragments were fixated in situ with compressive cannulated screws after cleaning the nonunion ends, followed by iliac autograft. At the secondary stage, the humeral supracondylar varus osteotomy was performed after the nonunion was healed and the elbow range of motion recovered. The therapeutic effects were assessed by comparing the elbow range of motion, carrying angle and Mayo elbow performance score (MEPS) between preoperation and the final follow-up.Results:All the patients were followed up for an average of 44.5 months (range, from 27 to 64 months). The average healing time for obsolete nonunion of lateral humeral condyle was 81.3 days (range, from 55 to 120 days) after the primary operation and that for supracondylar varus osteotomy 51.1 days (range, from 45 to 60 days) after the secondary operation. The elbow range of motion was 129.0°±4.6° before operation and 138.0°±5.4° at the final follow-up, showing a significant difference ( P<0.001). The average carrying angle at the healthy side in 8 children was 5.4° (range, from 3° to 8°). The carrying angle at the affected side was 31.9°±4.7° (range, from 25° to 42°) before operation and 4.0°±2.2°(range, from 1° to 8°) at the final follow-up, showing a significant difference ( P<0.05). Their preoperative MEPS was 57.5 ± 6.5 (4 good cases and 4 poor ones) but 95.9±3.4 (6 excellent cases and 2 good ones) at the final follow-up, showing a significant difference ( P<0.05). Conclusions:Treatment of nonunion of lateral humeral condyle complicated with cubitus valgus can be effectively carried out by cleaning fibrous tissue in the nonunion gap, iliac autograft and fragments fixation in situ with compressive cannulated screws at the primary stage and supracondylar varus osteotomy at the secondary stage. Intraoperative preservation of the blood supply to the nonunited fragments is the key to successful management.
ABSTRACT
Objective To evaluate the clinical efficacy of arthrography in the treatment of lateral condylar fracture of humerus with displacement of ≤ 2 mm in children.Methods A retrospective study was performed in the 21 children with lateral condylar fracture of humerus who had received arthrography in their surgery at Department of Pediatric Orthopedics,Honghui Hospital,Xi'an Jiaotong University College of Medicine from April 2015 to December 2016.They were 14 boys and 7 girls,aged from 5 to 12 years (average,8.6 years).Their primary diagnosis was made within one week from injury and they all had a displacement of ≤ 2 mm.Of them,2 were treated by plaster fixation because intraoperative arthrography found no fracture of articular cartilage (group A),11 by simple closed pining because intraoperative arthrography found fracture of articular cartilage involving the joint space (group B),and 8 by open reduction and fixation with kirschner wire because intraoperative arthrography found displacement of the involved articular surface (group C).The therapeutic efficacy was evaluated at final follow-ups by the Dhillon scoring system.Results All the 21 children were followed up from 9 to 23 months (average,16 months).The fracture union time ranged from 8 to 10 weeks (average,9 weeks) for groups A and B and from 11 to 13 weeks (average,12 weeks) for group C.By the Dhillon scores at final follow-ups,the therapeutic efficacy was evaluated as excellent in one and as good in one in group A,as excellent in 8 cases,as good in 2 cases and as fair in one in group B,and as excellent in 6 cases,as good in one and as fair in one in group C.No early closure of epiphysis,osteonecrosis or fishtail deformity was found in either group A or group B;one case of partial limitation of elbow flexion or extension,one case of fishtail deformity and one case of femoral head necrosis were observed in group C.No infection or skin necrosis was found in any of the 3 groups.Conclusions Because intraoperative arthrography can definitely judge whether the articular surface is intact or unstable,it can make up for the insufficiency of X-rays in judging integrity of the articular surface.In combination with closed reduction,percutaneous puncture or open reduction and internal fixation,intraoperative arthrography can contribute to an increased rate of successful surgery,and reduced complications due to redisplacement.

BACKGROUND: Many studies have been conducted about cemented and uncemented total hip arthroplasty (THA). However, there are few reports about the differences between cemented and uncemented bipolar hemiarthroplasty in China. OBJECTIVE: To compare treatment effects of cemented and uncemented bipolar prostheses on fracture of femoral neck in the elderly. DESIGN, TIME AND SETTING: Comparative observation. The patients were selected from Department of Orthopaedics, Xi’an Red Cross Hospital from January 2004 to December 2005. PARTICIPANTS: 131 cases of femoral neck fractures (type Garden Ⅲ and Ⅳ) were selected from Department of Orthopaedics Xi’an Red Cross Hospital, including 39 males and 92 females, aged 79 years (ranging 65-98 years); 72 cases of left hip and 59 cases of right hip. METHODS: The patients with various basic diseases were given corresponding treatment before surgery. The operation was performed 3 or 4 days after admission by the same operator. The patients were randomly divided into two groups, who were separately treated with cemented or uncemented prostheses. The patients were followed up for 3 years after operation and the hip function was evaluated by Harris score. MAIN OUTCOME MEASURES: Hip function, Harris score, mortality revision rate, revision rate and complication incidence rate. RESULTS: During follow-up period, 6 in cemented group and 8 in uncemented group died. After 3 month of operation, 43 patients could walk independently, 15 needed walking aid, and 5 only acted on bed in cemented group. In uncemented group, 27 patients could walk independently, and 35 needed walking aid. In hospital, 9 patients of cemented group and 15 of uncemented group had complication. After 3 years of operation, 14 cases underwent revision in cemented group due to prosthesis loosening with revision rate of 23.73%, while only 5 patients underwent revision in uncemented group, including 4 cases of prosthesis loosening and 1 of femur split with a revision rate of 23.73%. One year after operation, there was no statistically significance in Harris scores between two groups. During follow-up period, there was no difference in acetabular abrasion between two groups, but the uncemented group had a higher medullary cavity possession rate. No prosthesis dislocation, heterotopic ossification, or bone dissolving was found. CONCLUSION: There were no differences in hip function between cemented and uncemented bipolar hemiarthroplasty for femoral neck fractures in the elderly during follow up.
