Lower Leg Fractures in Children and Adolescents-Comparison of Conservative vs. ECMES Treatment

Overlooked valgus bowing deformity in pediatric tibial shaft fractures with/without fibular involvement: Cause residual valgus alignment in 2-year follow-up

BACKGROUND

Children with a tibial shaft fracture often present with valgus malalignment, even when anatomical reduction had been achieved at the fracture site. Pediatric bony structure has more elastic bones than that of adults, it can cause bowing deformity. Therefore, we evaluated pediatric tibial shaft fracture for the presence of bowing deformity, associated risk factors, and its clinical significance.

HYPOTHESIS

There is an overlooked bowing deformity in pediatric tibial shaft fracture.

PATIENTS AND METHODS

Fifty-seven tibial shaft fracture patients aged 2 to 15 years with Risser stage 0 were retrospectively reviewed. Clinicoradiologic factors and radiographs taken within 3 post-traumatic months and at 2 years were assessed. To evaluate the tibial bowing deformity, the tibial interphyseal angle and tibial shaft angle were measured, and their differences were calculated as a tibial bowing angle.

RESULTS

Multivariate analysis revealed the tibial shaft fracture with fibular involvement is significantly associated with a higher initial tibial bowing angle (valgus deformity). The tibial bowing angle did not change over 2-year follow-up. A high initial tibial bowing angle (≥ 5°) was a significant risk factor for the persistence of valgus malalignment.

DISCUSSION

Pediatric tibial shaft fractures with/without fibular involvement carry the risk of valgus bowing deformity, which may not develop during post-traumatic growth but may be present at the time of injury. The risk is high if the tibial fracture is accompanied by a fibular fracture. This tibial deformity presents limited remodeling potential at 2-year follow-up.

LEVEL OF EVIDENCE

IV; retrospective study.

Child Fractures: Are We Getting More Surgical?

Historically, surgeries on the immature skeleton were reserved for open or articular fractures. In recent years, the improvement in the quality and safety of anesthesia, new imaging equipment, implants designed especially for pediatric fractures, associated with the possibility of shorter hospitalization time and rapid return to social life has demonstrated a new tendency to evaluate and treat fractures in children. The purpose of this update article is to answer the following questions: (1) Are we really turning more surgical in addressing fractures in children? (2) If this is true, is this surgical conduct based on scientific evidence? In fact, in recent decades, the medical literature demonstrates articles that support better evolution of fractures in children with surgical treatment. In the upper limbs, this is very evident in the systematization of the reduction and percutaneous fixation of supracondylar fractures of the humerus and fractures of the forearm bones. In the lower limbs, the same occurs with diaphyseal fractures of the femur and tibia. However, there are gaps in the literature. The available published studies show low scientific evidence. Thus, it can be inferred that, even though the surgical approach is more present, the treatment of pediatric fractures should always be individualized and conducted according to the knowledge and experience of the professional physician, taking into account the presence of technological resources available for the care of the small patient. All possibilities, non-surgical and/or surgical, should be included, always instituting actions based on science and in agreement with the family's wishes.

Tibia Fractures in Children: A Single-Centre 11-Year Retrospective Study for Evaluating the Management and Outcomes in an Acute General Orthopaedic Hospital

Introduction Tibia fractures are children's most typical lower limb fractures affecting their general and mental well-being. This study aims to evaluate the management and outcomes of displaced tibia fractures. Methods A retrospective study was conducted to review children up to 16 years of age with displaced tibia shaft fractures who received treatment in our department from January 2011 to December 2021. Fractures managed in the operating theatre and patients who completed follow-up until fracture healing were included in the study. Treatment procedures were assessed, and outcome was measured by hospital stays, complications and revision procedure incidences. Results The study included 74 patients (75 fractures, including one re-fracture). The patient's ages ranged from 2 to 16 years (median age: 11 years). Seven patients sustained open fractures (Gustilo I, II). Tibia diaphysis was the most common site of involvement. A total of 43 patients were treated by manipulation under anaesthesia and cast. Surgical fixation was directly proportional to increasing age (p<0.05). Overall, 74% of patients were treated by fixation when age was >10 years. Three patients needed conversion of casting to surgical fixation. One patient had re-fracture following a secondary injury after six months of initial tibia shaft fracture treated by casting. Five patients had complications, including delayed union, pin site and surgical site infections. Antibiotics were adequate to manage infections except in one patient who needed debridement. The average hospital stay was three days. The median number of follow-up X-rays was 4. The planned removal of all flexible nails, and the circular frame was done between 2 and 15 months, except for one that had delayed union. All the patients underwent clinical and radiological union at the end of the follow-up. Conclusion The treatment plan was dependent on the individual need of the patient and the fracture pattern. Children older than 10 years were more likely to undergo surgical fixation. The majority of fractures were treated by manipulation and cast in operating theatres. Better logistic support in the emergency department could reduce the burden on the operating theatre.

Elastic Stable Intramedullary Nailing for Treatment of Pediatric Tibial Fractures: A 20-Year Single Center Experience of 132 Cases

Objective: The aim of this study was to analyze the outcomes and complications in children treated with elastic stable intramedullary nailing (ESIN) for tibial fractures. Methods: The study included 132 patients (92 males) with a median age of 11 years (IQR 10, 15) treated with ESIN for displaced tibial shaft fractures or dia-metaphyseal distal tibial fractures from March 2002 to March 2022. The median follow-up was 118.5 months (IQR 74.5, 170). The primary outcome was success rate, while secondary outcomes were the time of bone healing, length of hospital stay, and associated injuries. Demographic data, type and nature of fracture, indication for surgery, healing time, operative time, complications of treatment, and time to implant removal were recorded. Results: Complete radiographic healing was achieved at a median of 7 weeks (IQR 6, 9). Most of the patients (n = 111; 84.1%) had fractures localized in the shaft of the tibia. The most common injuries were acquired by road traffic accidents (n = 42) and by a fall in the same level (n = 29), followed by injuries from sport activities (n = 21) or motorbike accidents (n = 18). Associated injuries were reported in 37 (28%) children. Fractures were closed in the majority of the children (n = 100; 76%), while 32 (24%) children presented with an open fracture. Children with open fractures were significantly older than children with closed fractures (13.5 years (IQR 10, 15) vs. 11 years (IQR 8.5, 14.5); p = 0.031). Furthermore, children with open fractures had a significantly longer hospital stay (7 days (IQR 5, 9) vs. 3 days (IQR 3, 6); p = 0.001), a higher rate of associated injuries (n = 14 (43.7%) vs. n = 23 (23%); p = 0.022), and a higher rate of postoperative complications (n = 7 (21.9%) vs. n = 8 (8%); p = 0.031). No intraoperative complications were recorded. A total of 15 (11.4%) postoperative complications were recorded. Most complications (60%) were minor complications, mostly related to the wound at the nail insertion site and were managed conservatively. A total of six (4.5%) patients required reoperation due to angulation of the fragments (n = 5) or refracture (n = 1). Conclusion: ESIN is a minimally invasive bone surgery technique and is a highly effective treatment for pediatric tibial unstable fractures with a low rate of complications. Based on the given results, surgical stabilization of the tibial fractures using titanium intramedullary nailing can be safely performed without casting with early physiotherapy.
