Direct discharge for children with a greenstick or torus fracture of the wrist is a non-inferior satisfactory solution to traditional treatment.

PURPOSE: Direct Discharge protocols (DD) can alleviate strain on healthcare systems by reducing routine outpatient follow-up. These protocols include low-complex musculoskeletal injuries, such as isolated greenstick fractures or torus fractures of the wrist in children. While there is consensus on the effectiveness of DD, there is a lack of injury-specific powered studies. This study compares treatment satisfaction between DD and traditional treatment in children with a greenstick fracture or torus fractures of the wrist. METHODS: Children with isolated torus or greenstick fractures of the distal radius or ulna were eligible for inclusion before (pre-DD cohort) and after (DD cohort) the implementation of DD in four hospitals. Traditionally, patients receive a (soft) cast and minimally one routine outpatient follow-up appointment. With DD, patients are discharged directly from the ED after receiving a brace and information, summarized in a smartphone app and a helpline for questions during recovery. The primary outcome was patient or proxy treatment satisfaction (0 to 10), and a power analysis was performed to assess non-inferiority. Secondary outcomes included complications, functional outcomes measured in Patient-Reported Outcomes Measurement Information System Upper Extremity (PROMIS UE), primary healthcare utilisation, and secondary healthcare utilisation (follow-up appointments and imaging). RESULTS: In total, 274 consecutive children were included to analyse the primary endpoint. Of these, 160 (58%) were male with a median age of 11 years (IQR 8 to 12). Pre-DD and DD treatment satisfaction did not vary statistically significantly for greenstick fractures (p = 0.09) and torus fractures (p = 0.93). No complications were observed. PROMIS UE showed no statistically significant differences before and after implementation of direct discharge protocol for torus (p = 0.99) or greenstick (p = 0.45) fractures. Secondary healthcare utilisation regarding follow-up was significantly lower in the DD-torus cohort compared to the pre-DD torus cohort, with a mean difference (MD) of - 1.00 follow-up appointments (95% Confidence Interval (CI) - 0.92 to - 1.13). Similar results were found in the pre DD-greenstick cohort compared to the pre-DD-greenstick cohort (MD): - 1.17 follow-up appointments, 95% CI - 1.09 to - 1.26). CONCLUSION: Direct Discharge is non-inferior to traditional treatment in terms of treatment satisfaction for paediatric patients with greenstick or torus fractures of the wrist compared to children treated with rigid immobilisation and routine follow-up. Furthermore, the results demonstrate no complications, comparable functional outcomes, and a statistically significant reduction of secondary healthcare utilisation, making DD a good solution to cope with strained resources for children with an isolated greenstick fracture or torus fracture of the wrist.

Management of Lingual Cortex Fracture of Mandible Using Lingual Arch Bar: A Finite Element Analysis of Reduction with a Pilot Clinical Trial.

Purpose: Fractures of lingual cortex are frequently left untreated leading to poor resolution of patient's symptoms and function. Positioning an implant on same side of fracture would provide better reduction. The study aims at improving stability offered by Erich arch bar placed on lingual surface, by Finite element analysis (FEA) along with a pilot clinical trial. Methods: Two FEA models were generated from CT scan of an individual having lingual cortex fracture: control model with labial arch bar and study model with lingual arch bar. Parameters assessed: Stress distribution (Mpa) along lines of osteosynthesis; Separation of fracture fragments (mm) across fracture line. Associated, was a clinical trial of 5 patients, managed by placing lingual arch bar. Feasibility of arch bar, post-operative pain, radiographic inter-fragmentary gap and complications were assessed clinically. Results: Lingual positioning of arch bar demonstrated less displacement (mm) of fracture fragments compared to labial placement (0.123 vs. 0.677) upon application of masticatory load. Insignificant lingual splay and lesser degree of stress distribution (Mpa) was observed (83.1 vs. 99.3) favoring placement of arch bar on lingual side. Clinical trial correlated with outcomes of FEA, resulting in improvement of patient's symptoms. Conclusion: FEA and supporting clinical trial provided an effective method of reduction for lingual cortical fracture.

Possibility of Avoiding Anesthesia in the Reduction of Greenstick and Angulated Forearm and Distal-End Radius Fractures in Children: A Comparative Study.

Introduction Greenstick and angulated forearm bone fractures are the most common fractures in children and invariably require closed reduction under anesthesia. However, pediatric anesthesia is somewhat risky and not always available in developing countries like India. Therefore, this study aimed to evaluate the standard (quality) of closed reduction without anesthesia in children and to determine satisfaction among parents. Materials and methods The present study included 163 children with closed angulated fractures of the distal radius and fracture shafts of both forearm bones, who were treated by closed reduction. One hundred and thirteen were treated without any anesthesia (study group) on an outpatient department (OPD) basis, whereas 50 children of similar age and fracture type underwent reduction with anesthesia (control group). After reduction by both methods check X-ray was done to evaluate the quality of the reduction. Results The average age of the 113 children in the present study was 9.5 years (range: 3.5-16.2 years), of which 82 children had radius or ulna fractures, and 31 had isolated distal radius fractures. In 96.8% of children, ≤10° of residual angulation was achieved. Furthermore, 11 children (12.4%) used paracetamol or ibuprofen for pain control in the study group. Moreover, 97.3% of parents stated that they would like their children to be treated without anesthesia if any fracture occurred again. Conclusions Closed reduction of greenstick angulated forearm and distal-end radius fracture in children in the OPD without anesthesia achieved satisfactory reduction and high parent satisfaction while reducing the risks of pediatric anesthesia and its associated complications.

Novel Use of a Shoulder Spica: Treatment for Midshaft Humerus Fracture in the Presence of Limb Deficiency.

Pediatric midshaft humerus fractures are typically managed with a hanging arm cast, Sarmiento bracing, coaptation splint, or a combination of these treatment options. Here we report a novel use of a shoulder spica cast in the treatment of a midshaft humerus fracture in the presence of limb deficiency. Current treatments proved unsuccessful in maintaining adequate alignment, specifically the varus deformity of the fracture. A shoulder spica was able to successfully maintain acceptable alignment throughout the duration of the patient's healing process. This nontraditional use of a shoulder spica cast shows the practicality of its ability to be utilized for the treatment of unique upper extremity orthopedic obstacles.

Greenstick Fractures of the mid- Radial and Ulnar Diaphysis with Volar Angulation.

The authors present the case of a patient who was brought to the emergency department (ED) with severe left forearm pain following a classroom fall. This incident exacerbated the fractures that the patient experienced three months earlier in an accident. He had partial fractures of the middle radial and ulnar diaphyses. A review of the various presentations of forearm fractures and the nonoperative and surgical treatment options are discussed.

Failure mechanisms and bending strength of Fuchsia magellanica var. gracilis stems.

In the course of biological evolution, plant stems have evolved mechanical properties and an internal structure that makes them resistant to various types of failure. The mechanisms involved during damage development and failure in bending are complex and incompletely understood. The work presented builds on a theoretical framework outlined by Ennos and van Casteren, who applied engineering mechanics theory to explain why different woody stems fail in different ways. Our work has extended this approach, applying it to a detailed analysis of one particular species: Fuchsia magellanica var. gracilis. When subjected to three-point bending, stems of this species exhibited one of two failure mechanisms: a plastic hinge or a greenstick fracture. We developed a predictive model using a computer simulation and a mathematical analysis using the theory of plastic bending. Required material properties were obtained from tests, the literature and imaging techniques. We found that greenstick fractures are more likely to occur in more lignified stems with a higher density. We discovered a new failure mode: an internal crack caused by tensile transverse stress. This work helps in understanding how plants have evolved their bending resistance and may assist in the creation of novel engineering structures inspired by these principles.

Entrapment of the Median Nerve after Elastic Intramedullary Nailing of a Pediatric Forearm Fracture.

Closed reduction and fixation with elastic intramedullary nails is a popular technique to treat displaced pediatric forearm fractures and has yielded good functional results. Postoperative neurological symptoms can be due to neuropraxia and expectative treatment has been advised for 3 months until further investigation is necessary. We present a case of an 11-year-old boy that presented with median nerve palsy 2 months after a displaced forearm fracture treated with elastic intramedullary nails. Ultrasound and nerve conduction study confirmed the presence of a median nerve entrapped in the callus of the radial fracture. Surgical exploration demonstrated that the nerve was twisted around the intramedullary device. After neurolysis and surgical repair the patient finally recovered 2 years after the operation. This case highlights the possibility of median nerve entrapment after reduction with elastic intramedullary nails. Symptoms should be recognized early, and urgent surgical exploration is needed to prevent irreversible damage.

Seven-year follow-up for malrotation of a radial diaphysis fracture in a child corrected by osteotomy for loss of motion: A case report.

A greenstick fracture is an incomplete fracture where the compressive side of the cortex is still intact but plastically deformed. The incidence of poor results following the closed treatment of greenstick fractures in children >10 years of age is seriously underestimated. Therefore, fixing the position of the forearm is important for initial treatment. In cases of greenstick fracture, the possibility of inadequate remodeling of angulated deformities during growth, and in particular, the lack of correction between rotational malalignment and growth when the diaphyseal forearm is involved in the fracture, should be considered. A male, 10-year-old, left hand-dominant, Asian patient fell while playing in the garden and was immediately assessed by an orthopedic doctor at an Emergency Orthopaedic Clinic. Initial examination revealed a deformity of his dominant left forearm and an angulated greenstick fracture of the radius. However, after 3 months, he developed loss of supination of his left forearm and complained of limitation of left forearm supination. Radiography demonstrated a volar angulation of 20°. The patient underwent open reduction, internal fixation and 10° bending with a plate for correction without corrective rotation. At 12 months after injury, the patient did not exhibit pain or limitation of the elbow and wrist. After follow-up for 7 years, the patient was able to perform normal day-to-day activities with no adverse symptoms. The present case indicated that corrective osteotomy is required following the loss of supination after a greenstick fracture of the diaphysis of the radius. The patient of the current study exhibited rotation due to the central band of the interosseous membrane. In the treatment of greenstick fractures, a radius apex angulation of 20° must be corrected via osteotomy due to loss of rotation. The present case indicated that corrective osteotomy of the radius apex alone without rotational correction, in combination with plate bending improved the loss of forearm rotation.

Correlation of Neonatal Birth-Associated Greenstick Skull Fractures with Perinatal Factors and Long-Term Outcome: Children with a Greater Number of Greenstick Skull Fractures Showed Poor Results in Terms of Long-Term Neurodevelopment.

OBJECTIVE: Skull fractures caused by birth injury are mainly compression and linear fractures, but the incidence is known to be rare. It has been recently suggested, however, that greenstick fractures (GSFs) are more common than compression or linear fractures that are detected through 3-dimensional reconstructed computed tomography. Therefore, this study was conducted to determine the correlation of GSF with perinatal factors, the accompanying head injury factors, and the long-term outcomes in neonates. METHODS: A retrospective study was conducted on correlations between GSF and perinatal and head injury factors for 295 neonates. In 160 neonates, the correlation with long-term outcome was investigated. RESULTS: In 295 neonates, 47 cases had 3 or fewer GSFs, 66 cases had 4-6, 82 cases had 7-9, and 100 cases had 10 or more. The number of GSFs was significantly associated with gestational age and mode of delivery among the perinatal factors, with brain swelling and cephalohematoma among the head injury factors. It was also associated with long-term outcomes. The cut-off value of the number of GSFs for a poor outcome by the area under the receiver operating characteristic curve was 6 or greater. CONCLUSIONS: It was concluded that GSF most commonly occurs as a birth-related skull fracture and that birth-related GSF is associated with perinatal factors, birth-related head injuries, and deterioration of long-term development. Therefore, efforts should be made to prevent GSF at birth.

Musculoskeletal Traumatic Injuries in Children: Characteristic Imaging Findings and Mimickers.

Musculoskeletal traumatic injuries in children demonstrate characteristic imaging findings. The physis is the most susceptible structure to traumatic injury. The periosteum in children plays a key role in rapid bone healing and stability. The main complications of fractures in children are premature physeal closure, potential limb length discrepancy, and angular deformities. Understanding the normal bone growth, healing, and complications of pediatric fractures is crucial for appropriate imaging diagnosis. This article discusses currently available imaging modalities with up-to-date techniques, underlying mechanisms, and characteristic imaging findings of musculoskeletal traumatic injuries and mimickers encountered in daily clinical practice.

Lung injury caused by greenstick fracture of the scapular body in a 6-year-old boy.

Complications caused by a scapular body fracture are rare, and usually occur due to concomitant injuries or nonunion. Intrathoracic displacement of a fractured scapula has only been described in two reports involving adolescents. In this report, we describe a 6-year-old boy with a parenchymal lung injury caused by a greenstick fracture fragment of the scapular body after being struck by a dump truck. Three-dimensional CT (3D CT) scan showed an incomplete fractured fragment impaling the left lung parenchyma resulting in pneumothorax, parenchymal contusion, and pneumatocele in the left upper lobe. The patient underwent emergency open reduction of the scapular fracture and chest tube insertion. A rare subtype of scapular fracture with resultant fragment rotation and intrathoracic penetration can injure the lung parenchyma. To the best of our knowledge, lung injury caused by incomplete fracture of the scapula in patients younger than 10 years has not been reported previously.
