Laura A Drubach
An important mandate when imaging pediatric patients is the reduction of radiation exposure to the lowest possible level consistent with good quality diagnostic imaging, so individual selection of radiopharmaceutical dosage and imaging technique is essential. Although the logistics of image acquisition and the approach to interpretation mirror the more common use in adults, the challenges of imaging young children typically require greater attention to patient preparation, positioning, and supervision during imaging, with the use of parental or family engagement in the procedure, gentle restraint, and occasionally the need for sedation...

Pott puffy tumor is osteomyelitis of the frontal bone with associated subperiosteal abscess causing swelling and edema over the forehead and scalp. It is a complication of frontal sinusitis or trauma. We present the case of an 8-year-old girl with frontal swelling. Imaging evaluation showed frontal osteomyelitis as a complication of frontal sinusitis with associated epidural and subperiosteal abscess. The patient was treated surgically and recovered well. This case highlights the need for high clinical suspicion and early diagnosis and management to prevent life-threatening complications...

INTRODUCTION: Posttraumatic osteomyelitis (PTO) is a feared complication after surgical fracture care. Late diagnosis can result in interrupted and prolonged rehabilitation programmes, inability to work, medical dependency, unnecessary hospital admissions, and high medical and non-medical costs. Primary aim of this study was to assess preferred diagnostic imaging strategies for diagnosing PTO amongst orthopaedic and trauma surgeons, radiologists, and nuclear medicine physicians. Secondary aims were to determine the preferred serum inflammatory marker for diagnosing PTO and the existence of a local hospital protocol to diagnose and manage PTO...

PURPOSE: High-energy proximal tibial fractures often accompany compartment syndrome and are usually treated by fasciotomy with external fixation followed by secondary plating. However, the initial soft tissue injury may affect bony union, the fasciotomy incision or external fixator pin sites may lead to postoperative wound infections, and the staged procedure itself may adversely affect lower limb function. We assess the results of staged minimally invasive plate osteosynthesis (MIPO) for proximal tibial fractures with acute compartment syndrome...

Osteomyelitis is an inflammation of bone marrow with a tendency for progression, involving the cortical plates and often periosteal tissues, with most cases occurring after trauma to bone or bone surgery or secondary to vascular insufficiency. Antimicrobial therapy and surgical débridement are the primary modalities of osteomyelitis treatment, although often it is associated with a prolonged course, requiring a large commitment between patient and clinician as well as sizable health care costs. Despite surgical and chemotherapeutic advancements, osteomyelitis remains difficult to treat, and no universally accepted protocol for treatment exists...

Introduction: The potential of the medial calf integument, as donor site for a free flap based on musculocutaneous branches of the medial sural artery, was first identified by Taylor and Daniel, following cadaver investigation. In 1981, Pontén described the fasciocutaneous sural flap as a reconstructive option for soft tissue loss of the lower extremity, particularly around the knee. Two years later, Donski and Fogdestram presented the distally based fasciocutaneous flap from the sural region followed by Montegut and Allen who considered the sural artery perforator flap as a viable alternative for the gastrocnemius myocutaneous flap...

Introduction: The sensory loss and alteration of the shape of the foot make the foot liable to trauma and pressure, and subsequently cause more callus formation, blisters, and ulcers. Foot ulcers usually are liable to secondary infection as cellulitis or osteomyelitis, and may result in amputations. Foot ulcers are a major problem and a major cause of handicaps in leprosy patients. The current study is to present our clinical experience and evaluate the use of sural flap with posterior tibial neurovascular decompression (PTND) in recurrent foot ulcers in leprosy patients...

INTRODUCTION: Open tibial fractures are orthopedic emergencies that may present with severe soft tissue damage. Free tissue transfer is often required when local tissues are insufficient and patients may require hospital transfer to tertiary care centers for this purpose. Although the negative impact of inter-facility transfer has been well demonstrated in trauma patients, less is known regarding transfers for lower extremity injury patients. This study investigates differences in outcomes based on transfer status after open tibial fracture...

Differential diagnosis of chronic post-traumatic osteomyelitis (CPO) from aseptic inflammation remains challenging, since both pathological processes share similar clinical symptoms. Here we utilized a novel targeted metallofullerene nanoparticle based magnetic resonance imaging (MRI) probe IL-13-TAMRA-Gd3N@C80(OH)30(CH2CH2COOH)20 to detect CPO in mouse tibia via overexpressed IL-13Rα2 receptors. The functionalized metallofullerene was characterized by X-ray photoelectron spectroscopy. Upon lipopolysaccharide (LPS) stimulation, macrophage Raw 264...

Kirschner wires (K-wires) are widely used for fixation of fractures and dislocations in the hand as they are readily available, reliable, and cost-effective. Complication rates of up to 18% have been reported. However, K-wire breakage during removal is rare. We present one such case illustrating a simple technique for retrieval. A 35-year-old male presented with a distal phalanx fracture of his right middle finger. This open fracture was treated with K-wire fixation. Postoperatively, he developed a pin site infection with associated finger swelling...

The reamer-irrigator-aspirator (RIA) system has been recently developed to decrease the incidence of osseous thermal necrosis and fat embolism associated with intramedullary reaming of long bones in trauma cases. This is achieved by continuous irrigation and suction. Recently, the use of RIA has been expanded to harvest bone graft and debride the medullary canal of long bones in cases of osteomyelitis and intramedullary tumors. Additionally, the collection system of this device has been utilized for its ability to capture bone graft and marrow aspirate...
