Clinical consequence of the 4-week X-ray control after ESIN osteosynthesis of forearm fractures in children

PurposeThe absence of evidence based general guidelines for radiographic follow-ups of pediatric diaphyseal forearm fractures treated with ESIN results in an arbitrary array of X-ray examinations. In most pediatric traumatology departments, an X-ray check is carried out 4 weeks after ESIN osteosynthesis of forearm shaft fractures to detect incipient consolidation of the fracture. However, the elevated sensitivity to ionizing radiation requires special precautions in the pediatric populations. To prevent the indiscriminate use of this diagnostic tool it is necessary to assess the consequence of routinely taken X-rays at the 4-week follow-up.MethodsThis retrospective analysis included 219 pediatric patients who underwent ESIN treatment for a diaphyseal forearm fracture between 2010 and 2018 at the same pediatric trauma center. The primary outcome was defined as the prevalence of aberrant radiographic findings (ARF) during the 4-week follow-up with an otherwise normal clinical course and examination. Pathologies in the physical exam and irregularities in the medical history were summarized as non-radiological abnormalities (nRD). Binary logistic regression was calculated to identify risk factors associated with an increased likelihood of an ARF.ResultsOf the 219 pediatric patients included, 123 patients had no nRDs at the 4-week follow-up. Only one patient was found to have an ARF (absolute risk = 0.008). Regression showed that the odds of receiving an ARF increased significantly as other nRDs were detected (p = 0.012, OR 14.554). A positive correlation was found especially for irregularities in the medical history (n = 59, p = 0.003, OR = 8.134).ConclusionThis study provides evidence that standardized radiographic follow-up 4 weeks after surgical treatment has no clinical consequences if the course of the fracture is otherwise uneventful. It should be strictly reserved for pediatric patients with a complicated course.

Removal of Forearm Plate Leads to a Higher Risk of Refracture-A Systematic Review and Meta-Analysis.

Plate fixation is the preferred method for treating forearm shaft fractures. However, it remains controversial regarding the necessity of implant removal after bone union. This review aims to assess refracture risk after plate removal. We searched various data sources, including PubMed, Embase, Web of Science, and Cochrane Library. A total of 6749 papers were identified, of which 23 studies were eligible for final quantitative syntheses. Subgroup analyses and sensitivity analyses were conducted to reduce heterogeneity and make the results more reliable. The total risk difference (RD) was 0.06 (0.04-0.09), indicating that the difference was significant. In the "Reasons for Removal" subgroup analysis, the RD of the "No Symptom" subgroup was 0.07 (95% CI = 0.04-0.11), while the RD of the "Symptoms" subgroup was 0.04 (95% CI = -0.02 to 0.10). In the "Plate Type" subgroup analysis, the RD of the "LCP" subgroup was 0.07 (95% CI = 0.02-0.13), while the RD of the "DCP" subgroup was 0.07 (95% CI = 0.01-0.13). After omitting each study one by one, the RDs were all significant. Plate retention is significantly associated with a lower rate of refracture than plate removal. Consequently, it is not recommended to remove implants, especially for patients without implant-related symptoms, but more reliable evidence is still needed. The review was registered on PROSPERO and the registration ID is CRD42023424743, and a protocol was not prepared.

Elastic stable intramedullary nailing in paediatric diaphyseal forearm fractures – a retrospective analysis of 201 cases

BackgroundForearm shaft fractures are common injuries, often caused by falling from a fully-upright position or falling off a bike. They can be treated nonoperatively or surgically with intramedullary nailing or plates. The method of choice for treating pediatric forearm shaft fractures is the application of elastic stable intramedullary nailing (ESIN)|. The aim of the study was to evaluate ESIN in pediatric patients with forearm shaft fractures based on radiological images, and determine the etiology and complication rate associated with the injury.MethodsThe study included 201 patients, 30.5% female 69.5% male, aged 1 to 17 years (mean 9.1 years; SD = 3.2), all had been diagnosed with a fracture of the forearm shaft and had been treated surgically with ESIN. In addition, all possessed a complete set of X-ray images and had attended a minimum six-month follow-up examination of the forearm. Axial alignment was evaluated retrospectively in the anatomical (AP) and lateral (LAT) positions. In total, 402 radiographs were examined. Of the injuries, 68% occurred during sports activity and 75% involved both the radius and the ulna.ResultsUnion was observed in all cases. Mean axial alignment values in AP and LAT X-ray or both the ulna and radius were satisfactory. Axial alignment values were not influenced significantly by age, type of surgery, type of fracture or etiology. Plaster cast application (9.8% of cases) significantly influenced radius axial alignment. The complication rate was 11.4% (n = 23). Significantly more complications were observed in patients receiving open reduction internal fixation (ORIF) (p = 0.0025).ConclusionThe ESIN technique is an effective treatment for forearm diaphyseal fractures in children, with good results regarding reduction and bone healing, indicated by x-ray.

Open reduction and plate fixation of fractures of both bones in the forearm in Klippel-Trenaunay-Weber syndrome: a case report

Klippel-Trenaunay-Weber syndrome (KTWS) is a rare disease characterized by vascular malformations, port-wine staining, and soft tissue and bone hypertrophy. Lesions occur in the lower extremities in 95% of cases, whereas only 5% occur in the upper extremities. Several case reports have described the treatment of fractures in the lower extremities in patients with KTWS. However, the risk of massive bleeding, bone deformity, and poor bone quality can lead to suboptimal surgical outcomes. No reports describing the treatment of forearm shaft fractures in KTWS could be found in the English-language literature. Intramedullary nailing is difficult due to the deformed bone and the risk of nonunion. Open reduction and internal fixation (ORIF) should be considered with caution in KTWS patients due to the risks of intraoperative bleeding and wound problems. The authors report that satisfactory results were obtained with ORIF after preoperative vascular embolization in a 60-year-old KTWS patient with fractures in both bones of the forearm.

Both-Bone Forearm Shaft Fractures Treated with Compression Plate Fixation in Adults: A Systematic Review on Adverse Events and Outcomes.

Both-bone forearm shaft fractures (BBFFs) in adults carry a significant risk of adverse events (AEs). Based on the current literature, there is considerable variance in AE incidence reporting. We aimed to systematically review the literature on BBFFs in adults treated with compression plate fixation, assessing AEs and long-term outcomes. We performed a systematic review based on the PubMed database on the current literature on adult BBFFs treated with open reduction and internal fixation with compression plates. Two authors independently collected the data, and a third author resolved disagreements between the 2 reviewers. The primary outcome measure was postoperative AEs, whereas the secondary outcome was to review the long-term outcomes. We evaluated the methodological quality of the studies with a modified version of the Coleman Methodology Score. Fifteen studies (12 retrospective case series and 3 randomized controlled trials) met the set inclusion criteria. In total, there were 944 patients, of whom 24% (n = 224) experienced some AEs, and 14% had major AEs requiring secondary operations or remaining persistent. The most common AEs were postoperative nerve injuries (incidence 7%, n = 64/944) and fracture nonunion (incidence 5%, n = 45/944). Disabilities of the Arm, Shoulder, and Hand scores were available for 135 patients (5 studies), with a mean score of 12.5 (range 0-61). According to the modified Coleman Methodology Scores, there were 2 good-, 1 fair-, and 12 poor-quality studies among the included studies. BBFF compression plate fixation in adults poses a relatively high AE risk (24%). According to available patient-reported outcomes and range of motion measurements, the average postoperative outcomes are good, although a minor disability typically persists to some extent. There is a need for high-quality prospective trials assessing the treatment and outcomes of BBFFs in adults to improve forearm fracture treatment. Level III.

Greenstick fractures of the forearm shaft-Is it obligatory or facultative to break the cortex?

To break or not to break-That is the question that has been asked in pediatric traumatology for many years regarding the treatment of greenstick fractures of the diaphyseal forearm shaft. The frequency of greenstick fractures of the forearm shaft in children and adolescents; the influence of breaking the fracture on the refracture rate. Analysis and discussion of relevant articles, analysis of the refracture rate of pediatric greenstick fractures of the forearm shaft in our own patient population. Greenstick fractures frequently occur in the area of the forearm shaft and incomplete consolidation leads to an increased refracture rate. In the patient collective of the authors of 420 children with greenstick fractures of the diaphyseal forearm, there was arefracture rate of 9.5%; however, the rate for non-completed fractures was significantly higher compared to the group with completed fractures (15.2% vs.3%). While in the subgroup of conservatively treated fractures (n = 234), breaking the intact cortex significantly reduced the refracture rate, breaking the intact cortical bone during surgical treatment with elastic stable intramedullary nailing (ESIN) did not change the refracture rate. As part of the conservative treatment of greenstick fractures of the diaphyseal forearm, completing the fracture can be recommended in order to lower the refracture rate. Completing the fracture does not appear to be necessary during surgical treatment using ESIN.

Focused High-Energy Extracorporeal Shock Wave Therapy (ESWT) for Bone healing Disorders of the Forearm and the Hand

ESWT is a non-surgical treatment option but can also be used in addition to surgical treatment (stabilisation, freshening, defect filling, removal of discomforting osteosynthesis material) for the treatment of delayed bone healing (DBH) and non-union (NU). Its value as well as influencing factors on the upper extremity have not been adequately quantified so far. Sixty cases were retrospectively studied after application of focused high-energy ESWT with regard to healing rate and consolidation time. The influence of age, location, time of treatment and treatment prior to and concurrent with ESWT were analysed. In 70% of the cases, healing occurred after a median of 2.4 months (DBH) and 2.8 months (NU). The median age of healed (DBH 44 y., non-union 35 y.) and non-healed (DBH 51 y., NU 37 y.) did not differ significantly. The time between trauma/surgery and ESWT was 4.2 months for DBH in healed and 3.7 months in non-healed without a significant difference, and 27 months for NU in both healed and non-healed. Age and smoking status also had no influence. The healing rate was highest at metacarpal bone/finger/thumb (91%), followed by forearm shaft (88%), epiphysis/metaphysis of the forearm (67%), and, lastly, carpal bones (59%). After conservative pre-treatment, 55% healed, compared with 67% after more than two previous surgeries, 73% without any pre-treatment, and 75% after one previous surgery. Further analysis of surgical pre-treatment showed 85% healing after ORIF alone, 64% without previous surgery, and 57% healing after ORIF with bone grafting/debridement. Intraoperative ESWT combined with bone debridement/transplantation and ORIF resulted in 67% healing, compared with 86% in combination with ORIF alone. ESWT alone or with only minimal measures (removal of osteosynthesis material) led to 70% consolidation. ESWT is equally effective at any stage of a bone healing disorder. The principles of stability and filling of bone defects must also be taken into account when using ESWT; then ESWT alone or combined with surgery is equally effective. The negative influence of bone defects/resorption is still detectable even with ESWT. Furthermore, treatment of the scaphoid is more problematic compared with other locations. Previous surgery is not a negative factor, even with osteosynthesis material in situ.

Assessment, Diagnosis and Management Strategies for Forearm Shaft Non-union: A Contemporary Perspective.

Forearm non-union poses a challenge in orthopaedic surgery due to its intricate anatomy and functional significance. This review provides a comprehensive overview of the assessment, diagnosis and management of forearm non-union. Initial evaluation involves a meticulous history, physical examination and imaging studies to identify factors contributing to non-union, including infection. Surgical approaches are discussed, with emphasis on restoring biomechanical stability and promoting bone healing. Treatment options range from autografts to allografts, with considerations for vascularised bone transfers in complex cases. Decision-making strategies are outlined, considering patient-specific factors and individualised treatment plans. Special considerations for specific types of forearm non-unions are addressed, along with postoperative care protocols to optimise healing and functional outcomes. Overall, this review aims to provide clinicians with a comprehensive understanding of forearm non-union management based on current evidence and clinical practice.

The Outcomes of Intra-Medullary Square Nail for Adult Both Bone Forearm Shaft Fractures

Background: Forearm shaft fractures are common in developing countries. Anatomical reduction of these fractures using plates and screws is considered an accepted treatment mode. Like other shaft fractures, this can be treated with intramedullary nails like square nails, Rush nails, and interlocking nails. This study evaluates radiological and functional treatment results using square nailing. Methods: A prospective study was conducted on 100 adult patients with diaphyseal forearm fractures over 3 years. Out of 100 patients, 68 were men, and 32 were women. Patients were followed up at 2 weeks, 6 weeks, 8 weeks, and then every 3 months till 1 to 1.5 years. We have used criteria described by Anderson et al. and the shortened version of the Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score for functional evaluation of the patients. Results: Out of 100 patients, the union was achieved in 88 patients, while the rest 12 patients required re-surgery. 4 patients had delayed union, 4 patients developed an infection at the ulnar entry site, and 3 patients developed bursitis of olecranon bursa. Conclusion: Intramedullary nailing of both bone forearm shaft fractures using square nails can give satisfactory results in most cases, comparable with treatment by plates and screws, and provides an alternative, cost-effective treatment of both bone forearm shafts fractures with good cosmesis owing to small incisions.

Evaluation of Fixation of Fracture Shaft of Radius Ulna without Tourniquet

Background: Plate fixation is the mainstay of care for distal forearm shaft fractures in adults. By and large, volar or dorsal plating is used for radial shaft fractures. The radius's lateral surface offers an equal and constantly curved region for inserting a plate. The radial bow may be readily evaluated and restored after surgery. A prospective investigation was performed to examine the result of lateral plating of radius shaft fractures. Objective: In this study our main goal is to evaluate the treatment outcome of fixation of fracture shaft of radius ulna. Method: The research was conducted at tertiary medical hospital and district general hospital, Dinajpur included 100 patients. Several of them had broken both of their forearm bones, while others had broken only the radial shaft. Within 36 hours of damage, all patients were fixed with a 3.5 mm restricted contact dynamic compression plate or locking compression plate on the lateral surface of the radius. Typical procedure was used to repair the ulna. Results: During the study, majority were belong to 32-40 years age group, 36%. Followed by 20% were belong to 41-50 years age group, 11% belong to 20-31 years age group. In addition to that, 80% were male. 75% had fractured both of their forearm bones. Followed by 70% had closed fractured type, 35% had motor vehicle accident and lastly 85% had middle third radial shaft. Union was assessed by gradual disappearance of the fracture line and/or development of bridging callus at the fracture site. After getting treatment, 89% patients had excellent results, 8% had satisfactory and 1% had unsatisfactory result. There was 1% failure (nonunion). Conclusion: As compared to conventional methods, radial lateral plating holds promise as a viable option. Longitudinal studies with larger patient groups and study criteria are needed to confirm the potential advantages and validate our results.

Girl predominance in trampoline-related forearm shaft fractures and their increasing incidence since 2000

BackgroundThere are reports of increasing incidence of forearm shaft fractures in children. Their treatment has been preferably nonoperative but surgical fixation has gained popularity due to elastic stable intramedullary nailing. We aimed to study whether the incidence of pediatric both-bone forearm shaft fractures and their operative care have changed since year 2000. Trampoline injuries, in particular, and their treatment, re-displacement and short-term outcomes were the secondary outcomes of the study.MethodsA population-based study in the geographic catchment area of Oulu University Hospital district in 20-years of time period (2000 – 2019) was performed. Altogether 481 diaphyseal both-bone forearm fractures in children (< 16 years) were included. Age- and sex-related incidence rates were determined, by using the official numbers of the population-in-risk by Statistics Finland. Trampoline jumping and other types of injury were reviewed, as well as particulars of treatment and outcomes.ResultsThe incidence of diaphyseal both-bone forearm fractures increased from 9.4/100 000 in 2000–2001 to 41.7/100 000 in 2018–2019 (P < 0.001). Surgical treatment increased respectively (from 8.8/100 000 in 2000–2001 to 35.3/100 000 in 2018–2019, P < 0.0001). Trampoline injuries explained one in three (29%) of all fractures; they increased from 0% in 2000–2001 to 36.6% in 2018–2019 (P < 0.001). During the last four years of the study (2016–2019), most trampoline-related injuries occurred among girls (61.2%), compared to boys (38.8%) (P = 0.031). Trampoline-related injuries comprised 46.9% of all fractures in girls, compared to 26.0% among boys (Diff. 20.8%, 4.7% to 36.1%, P = 0.009). The mean age of the patients elevated from 6.4 years (2000–2001) to 8.6 years (2018–2019) (P = 0.015). Boys predominated (69.6%) in 2000–2009 but during the last ten years, there was no statistical difference in distribution between the genders (males 54.6%, P = 0.11).ConclusionsDuring the twenty-year’s of study period, the incidence of pediatric diaphyseal forearm fractures increased fivefold. Trampolining was the most usual single reason for the fractures. More attention should be focused to increase the safety of trampoline jumping, in particular among the girls.

The FRISK (Fracture Risk)-A New Tool to Indicate the Probability of Fractures.

Increasing patient inflow into the emergency department makes it necessary to optimize triage management. The scope of this work was to determine simple factors that could detect fractures in patients without the need for specialized personnel. Between 2014 and 2015, 798 patients were admitted to an orthopedic emergency department and prospectively included in the study. The patients received a questionnaire before contacting the doctor. Objective and subjective data were evaluated to determine fracture risk for the upper and lower extremities. The highest risk for fractures in one region was the hip (73.21%; n = 56), followed by the wrist (60.32%; n = 63) and the femoral shaft (4 of 7, 57.14%; n = 7). The regions with the lowest risk were the knee (8.41%; n = 107), the ankle (18.29%; n = 164), and the forearm shaft (30.00%; n = 10). Age was a predictor for fracture: patients older than 59 years had a risk greater than 59.26%, and patients older than 90 years had a risk greater than 83.33%. The functional questions could exclude fractures. Three factors seem to be able to predict fracture risk: the injured region, the patient's age, and a functional question. They can be used for a probatory heuristic that needs to be proven in a prospective way.

“You’re O.K. Anesthesia”: Closed Reduction of Displaced Pediatric Forearm and Wrist Fractures in the Office Without Anesthesia

Angulated wrist and forearm fractures are among the most common pediatric fractures, and they often require closed reduction with anesthesia. There are several issues associated with pediatric anesthesia including the low but non-zero risk of significant complications, increased physician and staff time and effort, and increased cost. Despite these issues, there have not been any studies to prove that using anesthesia results in better outcomes or higher caregiver satisfaction in comparison to performing closed reductions without anesthesia. The purpose of this study was to evaluate the quality of closed reductions of angulated pediatric wrist and forearm fractures and to determine caregiver satisfaction with an anesthesia-free reduction technique. This study included 54 pediatric patients with closed, angulated fractures of the radius or combined radial and ulnar shafts. All closed reductions were performed by a single pediatric fellowship-trained orthopaedic surgeon in the office setting without any anesthesia. Radiographs were obtained to assess the quality of the reduction. At the first follow-up visit, caregivers were asked about their interim use of pain medications. Caregivers were later surveyed about patient use of analgesics and their satisfaction with an anesthesia-free reduction technique. The average age of the 54 patients in this study was 9 years (1.8 to 16.8y). Thirty-three fractures were combined radial and ulnar forearm shaft fractures, 18 were distal radius fractures, and 3 were radial shaft fractures. ≤10 degrees of residual angulation was achieved in 98% of patients. Nine percent (5/54) of the patients used ibuprofen or acetaminophen for pain control. Seventy eight percent (42/54) of the caregivers responded to the telephone and email surveys. All responding caregivers stated that the patients returned to full function and had satisfactory outcomes. Ninety eight percent (41/42) of the caregivers stated they would choose the same anesthesia-free reduction technique again. Closed reduction of angulated pediatric wrist and forearm fractures in the office without anesthesia can achieve satisfactory reductions and high caregiver satisfaction while eliminating the risks and complications associated with pediatric anesthesia. Level IV Case series.

Retrograde intramedullary nailing of the radius in children: A pilot magnetic resonance imaging study of soft-tissue findings.

Purpose:Unstable forearm shaft fractures in children are preferably treated surgically using elastic stable intramedullary nails. The radius is nailed retrograde from the distal metaphysis. There is a risk of surgery-related soft-tissue complications during the operation. Close evaluation of occult surgery-related soft-tissue lesions has not been possible previously, due to the titanium alloy hardware used in the process. The aim of the present study was to evaluate the potential findings in the surrounding soft tissues after intramedullary nailing of the radius, by using magnetic resonance imaging.Methods:The study population comprised 15 pediatric patients with forearm shaft fractures treated by polylactide-co-glycolide biodegradable intramedullary nails and postoperatively evaluated via magnetic resonance imaging. The main outcome was signal abnormality in any tendon at the entry point postoperatively. Secondarily, other changes in the soft tissues related to nailing were determined. Furthermore, the precise location of the entry point and the anatomic characteristics of the soft-tissue tunnel were described.Results:In total, 5 of 15 patients (33.3%) had transient signal pathology in a tendon postoperatively. Edema around the superficial radial nerve was detected in 13 of 15 patients (86.7%). The most common surgical approach was between the extensor pollicis brevis and the extensor carpi radialis longus tendons, which was applied in 10 of 15 patients (66.7%).Conclusions:One in three patients exhibited transient and occult surgery-related intraparenchymal signal pathology in a tendon, after forearm intramedullary nailing. Caution with surgical prepare of the soft-tissue cleavage is recommended.Level of evidence: IV

Evaluation of functional outcome of forearm fracture in children treated with elastic nail (TENs)

Background: Forearm fractures are one of the most common injuries sustained by children and both bone forearm fractures are estimated around 40% of all pediatric fractures. Pediatric forearm fractures occur in approximately 1 in 100 children per year. Forearm shaft fractures in children are usually treated with closed reduction and cast immobilization and a good functional outcome is obtained, but few patients with gross displacement, angulations, soft tissue swelling due to edema, children nearing skeletal maturity, proximal third fractures, open fractures and displacement after closed manipulation and cast immobilization require surgical intervention. Greater controversy exists regarding the optimal method of fixation in children. Fractures in this age group that cannot be maintained in acceptable alignment with closed reduction can be treated with either intramedullary nails or open reduction and internal fixation with plates. The purpose of this study was to investigate the indications, techniques, clinical results, functional outcomes, possible complications and means of avoiding them in unstable forearm fractures in children treated with titanium elastic nails (TENs). Methods: Our prospective interventional study included Forty five children after application of inclusion and exclusion criteria, consent for study was taken from the parents.

A prospective study of surgical management in fracture of both bone forearm shaft using titanium elastic nailing system in pediatric patients

Introduction: Both bone forearm fractures are common orthopaedic injuries in pediatric population which present significant challenges to the orthopaedic community. It is not only important to treat them adequately but also to recognize the overall impact a fracture can have on a child, possibly limiting physical activity. Forearm fractures comprise 40% or more of pediatric fractures.Majority of these fractures can be treated conservatively with closed reduction and cast immobilization. A recognized failure rate has been reported up to 7% to 32%. Commonly two operative treatment modalities are employed at present: open compression plating and flexible intramedullary nailing. Each modality has advantage and disadvantage. Objective: Assess the functional outcome and complications associated with Titanium Elastic Nailing System in fracture of both bone forearm in pediatric patients.Materials and Methods: 20 Patients with both bone forearm shaft fracture aged between 6-16 years admitted to Chigateri General Hospital and Bapuji Hospital attached to J.J.M. Medical College Davanagere in the period from September 2019 to August 2021.Results: In our study, majority of the patients were boys, with an average age of 10.5 years with mid 1/3rd shaft transverse fractures being the most common, and self-fall while playing was the most common mode of injury. The surgery required minimum dissection, short operation time with hardly any risks of intraoperative complications. The average fracture union time was 9 weeks with patients recovering near normal functions of forearm at the earliest.We didn’t encounter any major post-operative complications in our study, and 95% of the patients had excellent range of motion at wrist, elbow and radio-ulnar joints and 5% had satisfactory range of motion.Conclusion: TENS nailing in both bone forearm shaft fractures in pediatric age group provides excellent results with advantages of early union, excellent recovery of function, minimal invasive and decreased time of surgery.

Determining the development stage of the ossification centers around the elbow may aid in deciding whether to use ESIN or not in adolescents’ forearm shaft fractures

Background and purpose — Elastic stable intramedullary nailing (ESIN) is the preferred method of operative stabilization of unstable pediatric forearm shaft fractures. However, the decision whether to use ESIN or open reduction and internal fixation (ORIF) in older children or teenagers is not always straightforward. We hypothesized that the development stage of the elbow would aid in evaluating the eligibility of the patient for ESIN. Patients and methods — All eligible children, aged <16 years who were treated with ESIN in Oulu University Hospital, during 2010–2019 were included (N = 70). The development stages of 4 ossification centers were assessed according to the Sauvegrain and Diméglio scoring. The proportion of impaired union vs. union was analyzed according to bone maturity, by using the optimal cutoff-points determined with receiver operating characteristics (ROC). Results — Development stage ≥ 6 in the olecranon was associated with impaired union in 20% of patients, compared with none in stages 1–5 (95% CI of difference 8% to 24%). Trochlear ossification center ≥ 4 was associated with impaired union in 17% of patients (CI of difference 7% to 36%) and lateral condyle ≥ 6 in 13% of patients (CI of difference 3.4% to 30%). Proximal radial head ≥ 5.5 was associated with impaired union in 18% of patients (CI of difference 7% to 39%). Interpretation — Recognizing the rectangular or fused olecranon ossification center, referring to stage ≥ 6, was in particular associated with impaired fracture healing. This finding may aid clinicians to consider between ESIN and plating, when treating forearm shaft fracture of an older child or teenager.

Randomized Controlled Trial of the Clinical Recovery and Biodegradation of Polylactide-co-glycolide Implants Used in the Intramedullary Nailing of Children's Forearm Shaft Fractures with at Least Four Years of Follow-Up.

The preferred surgical fixation of forearm shaft fractures in children is Elastic Stable Intramedullary Nailing (ESIN). Due to known disadvantageous effects of metal implants, a new surgical method using biodegradable polylactide-co-glycolide (PLGA) intramedullary nails has been developed but its long-term outcomes are unclear. The aim of this study was to compare the long-term outcomes of Biodegradable Intramedullary Nailing (BIN) to ESIN and assess the biodegradation of the study implants via magnetic resonance imaging (MRI). The study population of the prospective, randomized trial consisted of paediatric patients whose forearm shaft fractures were treated with BIN (n = 19) or ESIN (n = 16). Forearm rotation at minimally four years’ follow-up was the main outcome. There was no clinically significant difference in the recovery of the patients treated with the BIN as compared to those treated with the ESIN. More than half of the implants (57.7%, n = 15/26) were completely degraded, and the rest were degraded almost completely. The PLGA intramedullary nails used in the treatment of forearm shaft fractures in this study resulted in good function and anatomy. No unexpected disadvantages were found in the degradation of the implants. However, two implant failures had occurred in three months postoperatively.
