Treatment of pediatric forearm midshaft fractures: Is there a difference between types of orthopedic surgeon?

Intramedullary versus plate fixation of both bone forearm fractures in skeletally immature patients: a systematic review and meta-analysis

BACKGROUND

Both bone forearm fractures (BBFFs) are a common injury amongst the pediatric population. The main indications of surgical fixation are open, irreducible, or unstable fractures. The two most commonly used surgical techniques are closed or open reduction with intramedullary fixation (IMF) and open reduction with plate fixation (PF). The aim of this systematic review and meta-analysis was to determine which fixation method is superior for BBFFs.

METHODS

PubMed, Scopus, Web of Science, and CENTRAL were searched to identify studies comparing IMF and PF. We extracted data on union rates, complications, early hardware removal rates, reoperation rates, and radiographic, clinical, and perioperative outcomes.

RESULTS

Sixteen studies were included in the analysis, with a total of 922 patients (539 IMF and 383 PF). Similar union rates were achieved by both fixation technique. IMF was associated with a higher incidence of symptomatic hardware, and early hardware removal. Better restoration of the radial bow was observed with the PF group, especially in older children and adolescents. The rate of excellent function was comparable between groups, whereas better cosmesis was reported with the IMF group. Despite shorter fluoroscopy time and immobilization time, PF demonstrated longer tourniquet time, operating time, and hospital stay compared to IMF.

CONCLUSIONS

We found no significant difference between IMF and PF in terms of union rates and functional outcomes taking in consideration the merits and demerits of each technique. High-quality randomized controlled trials are, therefore, necessary to determine the superiority of one fixation technique over the other.

Outcomes and complications of Titanium elastic nailing for forearm bones fracture in children: our experience in a district general hospital in the United Kingdom

Intramedullary Titanium elastic nailing (TENS) is successfully used for irreducible and displaced forearm bone fractures in children. The purpose of this study was to report the potential complications and functional outcomes associated with paediatric forearm fractures treated with TENS nails. We retrospectively reviewed 65 children with displaced forearm bone fractures treated by TENS nailing with a mean follow-up of 5.84 months (4-12). Data detailing patient demographics, fracture characteristics, associated fractures, injury surgery interval, grade of the operating surgeon, methods of fixation, time to union, the timing of removal of the nail, and complications were collected and analysed. The mean age in our study was 9.13 years. 92% had fractures of both radius and ulna, 83.3% had fixation of both bones, and 16.7% had single bone fixation only. Open reduction was required in 38.5% of cases. The average time to fracture union was 10.34 weeks (6-20). The average time of implant removal was 20.12 weeks (9-32). We observed an overall complication rate of 41.5%. We noted a higher (56% vs 32.5%, p=0.059) complication rate in open reduction cases. According to the Price criteria, we had excellent to good results in over 98% of patients despite a slightly higher complication rate. Titanium elastic nailing is a safe, reliable method of internal fixation for irreducible or unstable fractures of both bones of the forearm in children. Open reduction of fracture was associated with higher complications. Despite higher overall complications, we noted excellent functional results in most cases.

Return to sport after forearm fractures in children: A scoping review and survey

Purpose

A common question faced by clinicians is when a child may return to sport after treatment for a pediatric forearm fracture. There are few published recommendations and fewer supported by evidence. The aims of this study were to summarize existing published recommendation for return to sport after pediatric forearm fractures and to conduct a survey to determine usual clinical recommendations.

Methods

A scoping review was performed on Ovid MEDLINE, Cochrane Central Register of Controlled Trials, Embase, Scopus, and Google Scholar in accordance with the Joanna Briggs Institute guidelines. In addition, 64 orthopedic surgeons were anonymously surveyed asking for recommendations regarding return to sport after pediatric forearm fractures. Participants were to assume children were 9 years old and played a sport with an average risk of forearm injury.

Results

Twenty-two publications for return to sport were retrieved. Children with distal radius buckle fractures safely commonly returned to sport by 4 weeks after initial injury, while survey respondents recommended over 6 weeks. Survey respondents valued fracture stability the highest when making return to sport recommendations. Children with simple, metaphyseal, single-bone fractures were usually allowed to return to sport at 8-10 weeks post-injury. Diaphyseal and complete fractures were prescribed longer return to sport intervals. Australian respondents also prescribed longer return to sport intervals.

Conclusion

Children with distal radius buckle fractures may return to sport by 4 weeks after initial injury, sooner than recommended. Published recommendations remain limited for other fractures. However, our survey suggests children with simple, metaphyseal, single-bone fractures may return to sport at 8-10 weeks. Children with diaphyseal and complete fractures should abstain from sport for longer than metaphyseal and greenstick fractures, respectively.

Trends in Operative Treatment of Pediatric and Adolescent Forearm Fractures Among American Board of Orthopaedic Surgery Part II Candidates

BACKGROUND

Pediatric and adolescent forearm fractures are among the most common injuries treated by orthopaedic surgeons. Recent literature shows that there has been an increased interest in operative management for these injuries. The purpose of the current study was to examine the trends in case volume, patient age, surgeon fellowship training, and postoperative complications of surgically treated pediatric forearm fractures over >15-year period of American Board of Orthopaedic Surgery (ABOS) Part II Oral Examination candidates.

METHODS

ABOS Part II candidates' Oral Examination Case List data from 2003 to 2019 was queried for all pediatric and adolescent (19 y of age and below) forearm fractures treated operatively. Patient demographics, fracture type, complications, and candidate fellowship type were identified for each case. Linear regression was used to delineate annual trends in patient age, complication rates, and case volume by fellowship type. Analysis of variance was performed to evaluate complication rates by fellowship type. Statistical significance for all comparative analyses was set at P-value <0.05.

RESULTS

A total of 4178 pediatric and adolescent forearm fractures (mean age: 12.6 y; SD: 3.7 y) were treated surgically among ABOS Part II Oral Examination candidates during their 6-month collection periods from 2003 to 2019. The mean patient age decreased significantly (P<0.001) over the study timeframe, while complication rates increased (P<0.001). Pediatric fellowship-trained orthopaedic surgeons performed significantly more cases than general orthopaedic surgeons over recent years (P<0.001). No significant trends were identified between fellowship type and complication rates. The overall surgical complication rate was 17%. The complication rate of open fractures was 24%, which was significantly >15% complication rate of closed fractures (P<0.001).

CONCLUSIONS

Fellowship-trained pediatric orthopaedic surgeons are performing an increasing number of pediatric and adolescent forearm fracture fixation when compared with other orthopaedic surgeons. The mean age of surgically managed pediatric forearm fracture patients has decreased from 2003 to 2019. There has been an increase in the rate of overall reported complications following pediatric forearm fracture surgery over recent years, without any significant association to any particular subspecialty. Future studies should evaluate the comparative effectiveness of surgical treatment of pediatric forearm fractures compared with closed management.

Radius shortening as a limiting factor for closed reduction in pediatric forearm fractures

INTRODUCTION

Diaphyseal forearm fractures in skeletally immature patients are common injuries that account for 30% of upper extremity fractures in this age group. There are cases with unstable injuries or unacceptable reductions, in which surgical resolution by reduction and stabilisation with percutaneous elastic endomedullary nailing is indicated. One of the advantages of this system is that it avoids an approach to the fracture site, allowing closed reduction in the vast majority of fractures. However, it is not always possible to achieve an acceptable closed reduction and opening of the fracture site is necessary. The aim of this study was to determine whether there are preoperative factors to predict the difficulty of performing closed reduction in these patients.

METHODS

A retrospective study of skeletally immature patients with acute diaphyseal forearm fractures treated with elastic endomedullary nailing by the same paediatric surgeon was performed. The primary outcome variable was defined as the need for open reduction; considered as a direct surgical approach to the fracture site. Demographic characteristics of the included patients and radiographic characteristics of the fracture were analysed.

RESULTS

We found that the median percentage of preoperative radial shortening in the closed reduction and open reduction groups was 1 and 5%, respectively; resulting in a statistically significant difference (p = 0.04).

CONCLUSION

Radial shortening on preoperative radiographs predicts an increased risk of requiring an open reduction of the fracture (39% association); thus we understand that this variable should be considered by the general traumatologist as a prognostic factor in defining the referral of these patients.

Flexible intramedullary nailing in the treatment of forearm fractures in children and adolescents, a systematic review

Background

Forearm fractures are common injuries among children and adolescents. Traditionally, they were managed conservatively with closed reduction and cast immobilization. The last decade there is an increasing trend towards operative treatment. The treatment modalities available include plate and screws, flexible intramedullary nailing and external fixation devices - rarely used nowadays. The aim of this systematic review is to investigate the indications of flexible intramedullary nailing in the childhood population, to compare its results with plating and to provide detailed information considering technical pitfalls and complications that may be encountered.

Materials and methods

An extensive search was performed in the electronic databases (PubMed, EMBASE) from their inception up to June 2019 in order articles relevant to this review to be retrieved. The search terms used were the following: forearm fracture, both-bone fracture, pediatric, nailing, fixation. 56 articles were considered suitable for inclusion.

Results

The indications for surgery are unstable and irreducible fractures, open and fractures with neurovascular compromise. As far as the fracture site is concerned, radius and ulna shaft fractures, radial head and Monteggia fractures are suitable for nailing.Although plates and nailing have comparable clinical outcomes and complication rates, flexible intramedullary nailing has the advantage of smaller incisions, less tissue disruption, shorter operative and hospital times and an ease in hardware removal.Controversy exists over the need of single or double nailing in both-bone fractures of the forearm. In addition, there is no consensus as to which is the preferred nail diameter. Yet, all the authors agree that open reduction must be considered after certain failed closed reductions in order compartment syndrome to be avoided.Flexible intramedullary nailing is not complication-free. Skin irritation, Extensor Pollicis Longus rupture, superficial radial nerve injury, delayed union or even nonunion, malunion and refractures are some of the complications that may be encountered.

Discussion

Flexible nails are excellent implants combining stability and elasticity. The procedure of passing the nails across radius and ulna is relatively simple, requiring a small learning curve. Flexible intramedullary nailing is an excellent treatment modality for the treatment of forearm fractures in children and adolescents.

Comparison of the outcomes of pediatric tibial shaft fractures treated by different types of orthopedists: A prospective cohort study

BACKGROUND

The objective of this study was to compare the outcomes of pediatric tibial shaft fractures treated with titanium elastic nail (TEN) by pediatric orthopedists and non-pediatric orthopedists.

MATERIALS AND METHODS

We conducted a prospective cohort study of 90 children of tibial shaft fractures, who were randomized to operative stabilization either by pediatric orthopedists (Group A, 45 cases) or by non-pediatric orthopedists (Group B, 45 cases) from April 2010 to May 2015. Demographic data and clinical characteristics (age, sex, weight, fracture side and type, cause of injury, number of fibula fracture and time from injury to operation) were comparable between the two groups before surgery. Clinical data, complications and functional outcomes between the two groups were recorded.

RESULTS

A total of 10 patients were lost to follow-up for various reasons and each group remained 40 cases. The mean follow-up period was 14.9 ± 1.9 months for Group A and 15.3 ± 2.2 months for Group B (P = 0.451). There was no significant difference in length of hospitalization, full weight-bearing time, fracture union time and TEN outcome scores between the two groups (P = 0.917, P = 0.352, P = 0.404, P = 506, respectively). However, Group A exhibited significantly shorter operation duration and less fluoroscopy times than Group B (P < 0.001 and P < 0.001, respectively). Also, there was a trend for patients of Group A to have lower rate of open reduction than Group B (P = 0.019). When comparing the total complications, no significant difference existed between the groups (P = 0.764).

CONCLUSIONS

Our results indicated that pediatric tibial shaft fractures treated surgically by pediatric orthopedists offered potential advantages including a shorter operating time, less times of fluoroscopy and a lower rate of open reduction. However, both pediatric and non-pediatric orthopedists could achieve satisfactory clinical results in treatment of these injuries.

Near-anatomical correction using a CT-guided technique of a forearm malunion in a 15-year-old girl: A case report including surgical technique

BACKGROUND

In this case report, we describe a left-arm both-bone forearm fracture in a 15-year-old girl who fell off a swing. Conservative treatment with an above-elbow cast failed, resulting in a malunion with functional impairment. The pro- and supination were 90/0/10, respectively. The patient complained of difficulties performing daily activities. For this pediatric case, a corrective osteotomy was proposed using a CT-guided technique aiming for maximum anatomical and functional outcome. It was the first time this technique was used in our hospital.

METHODS

A corrective osteotomy of the patient's left arm was performed using 3D printed templates to guide the osteotomy orientation. These templates were produced using specialized software in which CT images of her malunited left forearm were overlaid with the mirrored images of her healthy right forearm.

RESULTS

The postoperative CT-scan showed a near-anatomical reduction with close to 1° correction in all three planes, as compared to the preoperative planning. Three months after surgery, the patient had regained full function of her left forearm.

CONCLUSION

Although this was the first time this technique was used in our hospital, it resulted in excellent anatomical and functional outcomes making it a safe, reliable and precise treatment option that may be useful for even more complex corrections.
