Jan Lesensky, Daniel E Prince
Successful cure is achieved in almost 70% of patients with primary bone sarcomas with currently available therapies. Some soft tissue sarcomas require wide bone resection in order to achieve appropriate margins for cure of disease, and patients undergoing these procedures need durable reconstruction. Biological reconstruction has been shown to provide patients with superior long-term results over other alternatives. Distraction osteogenesis is well studied in the correction of deformities as well as in addressing some congenital musculoskeletal pathologies...

BACKGROUND: The scope of microvascular tissue transfer in the Head and Neck reaches from coverage of simple soft tissue defects to complex 3-D reconstructions using multiple or chimeric flaps. This paper summarises the presentation given at the Congress of the French Society of Oral and Maxillofacial Surgery in Marseille 2017. It was the aim of our work to add further elements to this wide spectrum of reconstructive possibilities. METHODS: For patients with small intraoral soft tissue defects in whom the use of a radial forearm flap would not be justified because of its donor site morbidity, but who nevertheless would take a benefit from a small free flap, we used mini-perforator flaps from the lower leg...

Spontaneous regeneration of bone tissue after mandibular resection is rare in adults, although it does often take place in children. Periosteum conservation appears to play a major role in this healing process. We here report regarding a 5-year-old boy who exhibited a large mandibular trabecular juvenile ossifying fibroma. The lesion was treated by mandibulectomy, with careful preservation of the periosteal layer and immediate reconstruction with a costal graft by an intra-oral approach. Monitoring over the course of a year revealed spontaneous mandibular regeneration, and it allowed for a series of measurements of the graft to be made...

OBJECTIVES: Accuracy on quantitative PET image analysis relies on the correct application of attenuation correction which is one of the major challenges for PET/MRI that remains to be solved. The purpose of this study is to evaluate the effect of MRI-based attenuation maps and the use of flexible coils on the quantitative accuracy of PET images with a special focus on large arteries. MATERIALS AND METHODS: PET/CT data from eight oncologic patients was used. PET data was reconstructed using attenuation maps with different level of detail emulating several approaches available on current PET/MRI scanners...

In the modern treatment of Charcot neuroarthropathy, beam screw fixation is an alternative to plate and screw fixation. Exposure is minimized for implantation, and this technique supports the longitudinal columns of the foot as a rigid load-sharing construct. A published data review identified a paucity of data regarding metatarsal intramedullary canal morphology relevant to beam screw fixation. The purpose of the present study was to describe metatarsal diaphyseal morphology qualitatively and quantitatively in an effort to provide data that can be used by surgeons when selecting axially based intramedullary fixation...

INTRODUCTION: Donor site seroma formation and prolonged drainage duration are common complications of using latissimus dorsi musculocutaneous (LDMC) flaps. The present retrospective study aimed to investigate the effect of types of back flap harvest on drainage duration and seroma formation rates. METHODS: Adult patients (n = 155) who underwent reconstruction with a latissimus dorsi flap from January 2010 to October 2015 were included in the study, of which 54 patients underwent breast reconstruction with a pedicled LDMC flap (LD breast group), 80 patients underwent an LDMC flap transfer for purposes other than breast reconstruction (LD nonbreast group), and 21 patients underwent soft tissue reconstruction with a thoracodorsal artery perforator (TAP) flap (TAP group)...

Many dental procedures allow for implant placement in partially or totally edentulous patients. Despite the availability of various implant and abutment types on the market, it often becomes quite challenging to achieve the biological and esthetic goals in a patient who has ridge deficiencies. Where problems will arise is from the lack of adequate bone quality and quantity.1,2 Soft tissue form and maintenance is also a consideration to evaluate.3 Primary reconstructive techniques following segmental mandibulectomy is evolving and improves quality of life...

PURPOSE: Differentiating tumor from its surrounding soft tissues is challenging for x-ray computed tomography (CT). Fluorescence molecular tomography (FMT) can directly localize the internal tumors targeted with specific fluorescent probes. A FMT system was developed and integrated onto a CT guided irradiator to improve tumor localization for image guided radiation. METHODS: The FMT system was aligned orthogonal to the cone beam CT onboard our previously developed image guided small animal arc radiation treatment system (iSMAART)...

Soft tissue sarcoma of the forearm, wrist and hand are rare. Their benign appearance leads often to primary inadequate treatment. Due to the complex anatomy of the hand and forearm, they are challenging to treat. The two goals are to obtain wide resection of the primary tumor while preserving function. Limb-sparing surgery is now the cornerstone for the treatment of most sarcomas of the forearm, hand and wrist. To achieve optimal oncological and functional outcomes, the surgical excision should be associated with early reconstructive procedures and a multidisciplinary meeting to define the treatment strategy including adjuvant medical treatments...

Malignant peripheral nerve sheath tumors are rare soft tissue tumors accounting for 3% to 10% of all soft tissue tumors. They are strongly related to neurofibromatosis type 1, an autosomal dominant disease, and are characterized by aggressive biologic behavior, high local recurrence rates, and frequent metastases. Although the major nerves of the lower extremities are a common location of these tumors, scarce cases have been reported of malignant peripheral nerve sheath tumors involving the interdigital nerves of the foot...

Neurofibromatosis Type 1 (NF1) is a neurocutaneous disorder that can have associated spinal abnormalities related to both bone and dural dysplasia. Thoracic meningoceles are one spine anomaly associated with NF1, although they are a fairly uncommon pathology. Surgical techniques to treat these meningoceles, usually undertaken only when the patient is symptomatic, are targeted at decreasing the size of the protrusion and improving lung capacity. Surgical interventions discussed in the literature include shunting the pseudomeningocele, primary repair with laminectomy, thoracoscopic plication, and reinforcement of the closure with cement, muscle, or fascia...

BACKGROUND: Eyelids are important structures and play a role in protecting the globe from trauma, brightness, in maintaining the integrity of tear films and moving the tears towards the lacrimal drainage system and contribute to aesthetic appearance of the face. Ophthalmic trauma is an important cause of morbidity among individuals and has also been responsible for additional cost of healthcare. Periocular trauma involving eyelids and adjacent structures has been found to have increased recently probably due to increased pace of life and increased dependence on machinery...
