Purpose: The treatment of displaced midshaft clavicle fractures in children remains controversial. The purpose of our study was to compare the outcome of displaced midshaft clavicle fractures in children who were managed operatively by flexible intramedullary nailing (FIN) with nonoperative treatment. Methods: A prospective review of 31 children (mean age 10.5 years) with displaced midshaft clavicle fractures treated either by FIN or nonoperatively and with at least a six-month follow-up was undertaken...

Fibular fractures in the setting of an unstable ankle joint require surgical fixation; however, several factors contradict open surgical correction. Severe soft tissue compromise can delay adequate fracture reduction and preclude the standard incisional approach. The soft tissue envelope in the setting of obesity, diabetes, and/or peripheral vascular disease further complicates definitive treatment. Poorly timed open fixation can lead to delayed healing of the incision site, with wound breakdown and the potential for hardware failure...

Intramedullary nailing is the mainstay of treatment for unstable intertrochanteric hip fractures. Various complications have been described with the use of these nails. We report an unusual complication whereby the lag screw completely missed the nail. We hypothesize that this previously unreported complication may be related to a specific flexible carbon fiber aiming device. Surgeon awareness and thorough intraoperative imaging are crucial to avoiding this complication.

Purpose: Traditional teaching for fixation of paediatric femur fractures recommends 80% nail diameter/medullary canal diameter ratio (ND/MCD) for successful maintenance of reduction. Prior studies have investigated this with stainless steel Enders nails. Our aim was to assess the impact of ND/MCD on maintenance of reduction and malunion rates in paediatric femur fractures treated with flexible intramedullary nails (FINs). Methods: Retrospective data was collected on all paediatric patients treated with FINs for diaphyseal femur fractures at a single tertiary care institution over a ten-year period...

Transdermal drug delivery (TDD) based on microneedles is an excellent approach due to its advantages of both traditional transdermal patch and hypodermic syringes. In this paper, the fabrication method of hollow out-of-layer hafnium oxide (HfO2 ) microneedles mainly based on deep reactive ion etching of silicon and atomic layer deposition of HfO2  is described, and the finite element analysis of the microneedles based on ANSYS software is also presented. The fabrication process is simplified by using a single mask...

L Claes
The dynamization of fracture fixation is a frequently used method to improve the fracture healing process; however, the term dynamization is used for different methods of altering the fixation of fractures during the bone healing process. The dynamization of intramedullary nail fixation by removing the interlocking screws is the most frequently applied method. This method can cause a telescopic movement between the nail and tubular bone that closes gaps in bony continuity and potentially compresses the fracture fragments...

Introduction: The treatment of pediatric femur fractures continues to evolve. In the past, many of these fractures required prolonged hospitalization in traction. More recently, flexible elastic nails have gained popularity. However, length unstable and comminuted fractures can present some unique challenges. To avoid common complications of elastic nailing in the setting of unstable fractures we describe a technique of augmenting this treatment with external fixation for cases requiring additional rotational or longitudinal stability...

PURPOSE: Traditionally, flexible intramedullary nails (FINs) are not to be used to fix femur fractures in patients > 50 kg (110 lbs). However, studies have not examined the efficacy of this technique in overweight and obese patients who may be under this 'weight cutoff'. The purpose of this study was to assess how patient body mass index (BMI) impacts the treatment of paediatric femur fractures managed with FINs. METHODS: Retrospective data was collected on all paediatric patients treated with FINs for diaphyseal femur fractures at a single tertiary care institution over a ten-year period...

Pediatric femoral shaft fractures present many challenging patient care decisions. Nonoperative treatment approaches still dominate care of the youngest age groups while surgical intervention is commonplace in virtually all older children. Treatment is determined primarily by patient age as modified by clinical factors including mechanism of injury, weight, and skeletal maturity. Infants can be successfully treated by placement into a Pavlik harness, whereas children younger than 5 years are most commonly treated by early reduction and spica cast immobilization...

Lower and upper limb length discrepancy and deformity, congenital or acquired, are amongst the most common conditions in children for orthopaedic referral. Over the last twenty years, surgical techniques have evolved in an attempt to decrease Healing Index and minimise these complications. Areas covered: The flexible intramedullary nailing (FIN) is a minimally invasive intramedullary osteosynthesis. In combination with an external fixator, it is appropriated for pediatric bone lengthenings and lengthening of bones of small diameter in adults...

A pediatric patient presenting with an open forearm fracture with segmental defect is rare, and the pediatric orthopedic literature to guide treatment is sparse. There are several described methods to treat the defect, including bone grafting and bone transport techniques. In addition, there are reports of fibular regeneration after resection if the periosteum is left intact. We present a case report of complete regeneration of over half of a pediatric radial shaft with an intact periosteum, after traumatic extrusion from an open fracture...

PURPOSE: The ideal canal fill for flexible intramedullary fixation of pediatric femoral shaft fractures is considered to be 80% based upon relatively few clinical studies. The purpose of this study is to assess the relationship between the summed nail to intramedullary canal diameter (ND/MCD) ratio and alignment at radiographic union following flexible intramedullary nailing (FIMN) of pediatric femoral shaft fractures. METHODS: An Internal Review Board approved, retrospective review of a consecutive series of patients who sustained a femoral shaft fracture treated by retrograde, stainless steel FIMN was performed at a single level 1 pediatric trauma center from 2005 to 2012...

Monitoring cardiovascular signals such as heart rate and blood flow provides critically important healthcare information about patients under medical care. However, when the sensors are worn for extended times, the sensors sometimes require higher mechanical compatibility with soft deformable tissues. In this paper, we report an attachable and flexible pulse sensor (bending radius: 2.4 mm), integrated with micro-inorganic photodetectors (thickness: 4.1 μm, photocurrent: 8.99 μA under 1.5 mW/cm(2)) and a red light emitting diode (620 nm), to monitor vital signals for extended times...

BACKGROUND: There has been a trend towards flexible intramedullary nailing for unstable tibial shaft fractures in the pediatric population, traditionally, utilizing a 2-incision technique with passage of one nail medially and one nail laterally. Our study aims to compare a single incision approach for flexible nailing of unstable tibial shaft fractures in pediatric patients to the traditional 2-incision approach. METHODS: Patients were selected for operative fixation if they had a length unstable tibial shaft fracture confirmed by fluoroscopy...

BACKGROUND: Flexible elastic nails, submuscular plating, and rigid locked intramedullary nails are common methods of fixation for pediatric femur fractures (PFF) in which the fracture table is used to aid reduction. Little is known about complications associated with fracture table application in PFF. The purpose of this study was to determine the incidence and risk factors associated with adverse outcomes related to fracture table application for the treatment of PFF. METHODS: A retrospective chart review of all children (younger than 18 y) treated for a femur fracture with the use of the fracture table between 2004 and 2015 at a single tertiary pediatric hospital was performed...

INTRODUCTION: Extraction of broken femoral nails in peri-implant fractures is becoming an increasingly common problem faced by orthopaedic surgeons. Different closed and open techniques for removal of broken nails have been previously described but due to variations in equipment and fracture configurations these methods are not always easily reproducible. We describe an open surgical technique using simple equipment that can be utilised when other methods of extraction have failed. CASE PRESENTATION AND SURGICAL TECHNIQUE: We present a case of a peri-implant fracture secondary to non-union involving a short cephalomedullary nail where the broken distal segment of nail was significantly more distal to the femoral fracture site...
