Sengab A, Krijnen P, Schipper IB. Risk factors for fracture redisplacement after reduction and cast immobilization of displaced distal radius fractures in children: a meta-analysis. Eur J Trauma Emerg Surg 2019; 46:789-800. [PMID: 31502066 PMCID: PMC7429528 DOI: 10.1007/s00068-019-01227-w] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2019] [Accepted: 08/31/2019] [Indexed: 01/01/2023]
Abstract
PURPOSE Displaced distal radius fractures in children are common and often reduced if necessary and immobilized in cast. Still, fracture redisplacement frequently occurs. This can be prevented by fixation of fracture fragments with K-wires, but until now, there are no clear guidelines for treatment with primary K-wire fixation. This meta-analysis aimed to identify risk factors for redisplacement after reduction and cast immobilization of displaced distal radius fractures in children, and thereby determine which children will benefit most of primary additional K-wire fixation. METHODS Eight databases were searched to identify studies and extract data on the incidence of and risk factors for redisplacement of distal radius fractures after initial reduction and cast immobilization in children. RESULTS Twelve studies, including 1256 patients, showed that initial complete displacement (odds ratio [OR] 4.69, 95% confidence interval [CI] 2.98-7.39) and presence of a both-bone fracture (OR 1.95, 95% CI 1.34-2.85) were independent risk factors for redisplacement. Anatomical reduction reduced the redisplacement risk (OR 0.14, 95% CI 0.05-0.40). No significant influence on redisplacement risk could be established for female sex, experience level of the attending surgeon, Cast Index < 0.8, Three-Point Index < 0.8 and patient's age. CONCLUSIONS For children with a displaced distal radius fracture, the presence of a both-bone fracture, complete displacement of the distal radius and non-anatomical reduction are risk factors for redisplacement after reduction of their initially displaced distal radius fracture. Children with one or more of these risk factors probably benefit most of reduction combined with primary K-wire fixation.

Abstract
BACKGROUND The frequency figures for epiphyseal plate injuries of long bones given in the literature are inexact and they probably occur with a frequency of 15% of all fractures of the growing skeleton. In order to be able to give correct figures in the future a classification system, such as the LiLa classification should be used, which does not attempt to be oriented to an assumed growth prognosis but is oriented to therapy and makes a strict differentiation between shaft and joint fractures. For epiphyseal joint fractures a differentiation must be made between those where the epiphysis is still open and those where the epiphysis has begun to close, in order to be able to incorporate all epiphyseal joint fractures and differentiate them from epiphyseal shaft fractures (epiphysiolysis). CLINICAL ASPECTS The growth prognosis encompasses stimulatory and inhibitory growth disorders as well as spontaneous correction of residual axial deviations. The prognosis is fundamentally dependent on the biological age of the patient by fracture, on the localization in the skeleton and the localization in the segment because the growth components of epiphyses are asymmetrically distributed in the segment. Stimulatory growth disorders in the actual growth phase < 10 years of age are the obligatory growth disorders which lead to overgrowth of the section of the skeleton affected. In an age over 10 years they lead to an also obligatory premature closure of adjacent or affected epiphyses which is expressed as a slight shortening. Asymmetrical stimulations are most common in the upper extremities following intra-articular fractures of the radial condyle as the obligatory growth disorder at this site. Asymmetrical stimulation is rare in the lower extremities after extra-articular metaphyseal valgus fractures of the proximal and distal tibia. Asymmetrical premature closure of the epiphysis in the upper extremities is rare in contrast to partial stimulation with less than 5% after extra-articular fractures of the distal radius and proximal humerus. Conversely, asymmetrical inhibitory growth disorders are found significantly more often in the lower extremities after extra-articular and intra-articular fractures of the distal femur, proximal tibia and distal tibia between 50% and 20%. "Spontaneous corrections" of residual axial deviations and side to side shifts after epiphyseal shaft fractures occur reliably without resulting in growth disorders, provided the patient is young enough. THERAPEUTIC TARGETS In cases of displacement the aim of therapy in epiphyseal shaft fractures is to reconstitute age-related and tolerable axes. For displaced epiphyseal joint fractures the aim is to reconstruct the joint surfaces. The basic principles of an efficient and targeted diagnostics and the therapeutic options for diminishing the clinical sequelae of growth disorders are discussed. CONCLUSION No growth disorders, which are to be expected as a result of every epiphyseal injury, can primarily be therapeutically avoided; however, better foundations can be achieved to reduce the clinical sequelae of growth disorders. Therapy can only follow the differentiation into shaft and joint (and not an assumed growth prognosis) and should integrate a scientifically proven and reasonable spontaneous correction for the patient. A classification must achieve a therapy-related uncoupling of the epiphyseal injuries into shaft and joint fractures.

Abstract
BACKGROUND The distal forearm fracture is the most common injury (40%) in pediatric traumatology. OBJECTIVES The treatment of distal forearm fractures in the growth phase contains two contrasting phenomena which are incompatible with the patient's interests and are discussed in this article. METHODS A selective literature search was carried out and selected cases are discussed. RESULTS On the one hand there is a unique property of the juvenile skeleton with an enormous potential for spontaneous correction enabling conservative treatment for the majority of fractures. This generally leads to healing without functional or cosmetic defects, even in cases of some minor residual angulations. In contrast, high rates of overtreatment are observed, such as unnecessary or repetitive reductions and operative interventions, which are not only the result of ignorance of the growth prognosis and of correct conservative techniques but also of economic factors as a consequence of medical economization as well as positive experiences gained in adults but which cannot be transferred to children. The management of distal forearm fractures should be reserved for unstable fracture types especially in adolescent patients with limited age-dependent potential for spontaneous correction. Angulated fractures should be treated using cast wedging in order to reduce angulation to a reasonable extent. The most frequently occurring stable torus fractures require immobilization only for analgesic reasons. Intolerable angulations as well as completely dislocated fractures are treated by closed reduction and stabilized with a Kirschner wire osteosynthesis depending on age. CONCLUSION Treatment of distal forearm fractures should be appropriate for children as well as highly efficient, by using a minimal amount of effort. Current forms of overtreatment have to be avoided because of moral and in particular economic reasons.

Angular malalignment as cause of limitation of forearm rotation: an analysis of prospectively collected data of both-bone forearm fractures in children. Injury 2014; 45:955-9. [PMID: 24629703 DOI: 10.1016/j.injury.2014.02.016] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/20/2013] [Revised: 01/26/2014] [Accepted: 02/02/2014] [Indexed: 02/02/2023]
Abstract
INTRODUCTION Although limitation of pronation/supination following both-bone forearm fractures in children is often attributed to an angular malunion, no clinical study has compared pronation/supination and angular malalignment of the same child by analysis of prospectively collected clinical data. AIM The purpose of this trial is to explore whether limitation of pronation/supination can be predicted by the degree of angular malalignment in children who sustained a both-bone forearm fracture. METHODS In four Dutch hospitals, children aged ≤16 years with a both-bone forearm fracture were prospectively followed up consecutive children for 6-9 months. At the final follow-up, pronation/supination and angular malunion on radiographs were determined. RESULTS Between January 2006 and August 2010, a total of 410 children were prospectively followed up, of which 393 children were included for analysis in this study. The mean age of the children was 8.0 (±3.5) years, of which 63% were male and 40% fractured their dominant arm. The mean time to final examination was 219 (±51) days. Children with a metaphyseal both-bone fracture of the distal forearm with an angular malalignment of ≤15° had a 9-13% chance of developing a clinically relevant limitation (i.e., <50° of pronation and/or supination), while children with an angular malalignment of ≥16° had a 60% chance. Children with diaphyseal both-bone forearm fractures with ≤5° of angular malalignment had a 13% chance of developing a clinically relevant limitation, which showed no significant increase with a further increase of angular malalignment. CONCLUSIONS Children who sustained a both-bone forearm fracture localised in the distal metaphysis have a higher chance of developing a clinically relevant limitation of forearm rotation in case of a more severe angular malalignment, while children with a diaphyseal both-bone forearm fracture had a moderate chance of limitation, irrespective of the severity of the angular malalignment.

Abstract
INTRODUCTION Both-bone forearm fractures in children frequently result in a limitation of pronation/supination, which hinders daily activities. The purpose of this prospective multicentre study was to investigate which clinical factors are related to the limitation of pronation/supination in children with a both-bone forearm fracture. METHODS In four Dutch hospitals, consecutive children (<16 years) who sustained a both-bone forearm fracture were included. Children were followed up for 6-9 months and data from questionnaires, physical examination and X-rays were collected. Univariate and multivariate logistic regression analyses were used to assess the relationship between limitation of pronation/supination (≥20°) and several clinical factors. RESULTS A group of 410 children with both-bone forearm fractures were included, of which 10 children missed the final examination (follow-up rate of 97.6%). We found that a re-fracture (odds ratio (OR) 11.7, 95% confidence interval (CI) 1.2; 118.5), a fracture in the diaphysis (OR 3.3, 95% CI 1.4; 7.9) and less physiotherapy during follow-up (OR 0.90, 95% CI 0.82; 0.98) were independently associated with a limitation of pronation/supination of 20° or more. CONCLUSIONS These findings imply that a re-fracture and a diaphyseal located fracture were associated independently of each other with a limitation of pronation/supination in children with a both-bone forearm fracture. Furthermore, in children with severe limitation extensive physiotherapy is associated with better functional outcome.

Abstract
INTRODUCTION This multicentre randomised controlled trial was designed to explore whether 6 weeks above-elbow cast (AEC) or 3 weeks AEC followed by 3 weeks below-elbow cast (BEC) cause similar limitation of pronation and supination in non-reduced diaphyseal both-bone forearm fractures in children. MATERIALS AND METHODS Children were randomly allocated to 6 weeks AEC or to 3 weeks AEC followed by 3 weeks BEC. The primary outcome was limitation of pronation and supination after 6 months. The secondary outcomes were re-displacement of the fracture, complication rate, limitation of flexion and extension of wrist and elbow, cast comfort, cosmetics, complaints in daily life and assessment of radiographs. RESULTS A group of 23 children was treated with 6 weeks AEC and 24 children with 3 weeks AEC and 3 weeks BEC. The follow-up rate was 98 % with a mean follow-up of 7.0 months. The mean limitation of pronation and supination was 23.3 ± 22.0 for children treated with AEC and 18.0 ± 16.9 for children treated with AEC and BEC. The other study outcomes were similar in both groups. CONCLUSIONS Early conversion to BEC is safe in the treatment of non-reduced diaphyseal both-bone forearm fractures in children.

Single-bone intramedullary fixation of unstable both-bone diaphyseal forearm fractures in children leads to increased re-displacement: a multicentre randomised controlled trial.

Abstract
INTRODUCTION Both-bone diaphyseal forearm fractures in children can be stabilised without cast by a flexible intramedullary nail in both the radius and the ulna. Adequate results with single-bone fixation combined with a complementary cast are also reported. However, because those results are based on a selection of children, this trial investigates whether single-bone intramedullary fixation, compared with both-bone intramedullary fixation, results in similar pronation and supination in children with an unstable diaphyseal both-bone forearm fracture. MATERIALS AND METHODS In four Dutch hospitals, 24 consecutive children aged <16 years with a displaced unstable both-bone diaphyseal forearm fracture were randomly allocated to single-bone or both-bone intramedullary fixation. Primary outcome was limitation of pronation and supination 9 months after initial trauma. Secondary outcomes were limitation of flexion/extension of wrist/elbow, complication rate, operation time, cosmetics of the fractured arm, complaints in daily life, and assessment of radiographs. RESULTS Between January 2006 and August 2010, 11 children were randomised to single-bone fixation and 13 to both-bone fixation. In the both-bone fixation group, two fractures were stabilized by only one nail. In both groups, median limitation of pronation/supination at 9-month follow-up was 5°-10°. In both groups operation time was similar but in the single-bone fixation group cast immobilisation was longer (median of 37 vs. 28 days). In four children, re-displacement of the fracture occurred in those fractures without an intramedullary nail. CONCLUSIONS These results caution against the use of single-bone fixation in all both-bone forearm fractures. This method may lead to increased re-displacement and reduced clinical results.

Abstract
Forearm fractures in children have a tendency to displace in a cast leading to malunion with reduced functional and cosmetic results. In order to identify risk factors for displacement, a total of 247 conservatively treated fractures of the forearm in 246 children with a mean age of 7.3 years (sd 3.2; 0.9 to 14.9) were included in a prospective multicentre study. Multivariate logistic regression analyses were performed to assess risk factors for displacement of reduced or non-reduced fractures in the cast. Displacement occurred in 73 patients (29.6%), of which 65 (89.0%) were in above-elbow casts. The mean time between the injury and displacement was 22.7 days (0 to 59). The independent factors found to significantly increase the risk of displacement were a fracture of the non-dominant arm (p = 0.024), a complete fracture (p = 0.040), a fracture with translation of the ulna on lateral radiographs (p = 0.014) and shortening of the fracture (p = 0.019). Fractures of both forearm bones in children have a strong tendency to displace even in an above-elbow cast. Severe fractures of the non-dominant arm are at highest risk for displacement. Radiographs at set times during treatment might identify early displacement, which should be treated before malunion occurs, especially in older children with less potential for remodelling.

Abstract
INTRODUCTION Displaced metaphyseal both-bone fractures of the distal forearm are generally reduced and stabilised by an above-elbow cast (AEC) with or without additional pinning. The purpose of this study was to find out if re-displacement of a reduced stable metaphyseal both-bone fracture of the distal forearm in a child could be prevented by stabilisation with Kirschner wires. METHODS Consecutive children aged <16 years with a displaced metaphyseal both-bone fracture of the distal forearm (n = 128) that was stable after reduction were randomised to AEC with or without percutaneous fixation with Kirschner wires. The primary outcome was re-displacement of the fracture. RESULTS A total of 67 children were allocated to fracture reduction and AEC and 61 to reduction of the fracture, fixation with Kirschner wires and AEC. The follow-up rate was 96% with a mean follow-up of 7.1 months. Fractures treated with additional pinning showed less re-displacement (8% vs. 45%), less limitation of pronation and supination (mean limitation 6.9 (± 9.4)° vs. 14.3 (± 13.6)°) but more complications (14 vs. 1). CONCLUSIONS Pinning of apparent stable both-bone fractures of the distal forearm in children might reduce fracture re-displacement. The frequently seen complications of pinning might be reduced by a proper surgical technique.

Abstract
We report on a 16-year-old boy with deformity of the forearm with painful functional limitation after a fracture of the distal radius associated with an unapparent lesion of the distal physis of the ulna suffered 4 years earlier. The lesion caused premature growth arrest in the ulna and a bowing of the distal radius with a carpal slip. It was treated with a corrective osteotomy in the radius together with a lengthening of the ulna, with excellent functional results.
