BACKGROUND: The primary aim of this study was to evaluate the outcomes of a series of patients with Charcot neuroarthropathy (CN) who were evaluated in a tertiary care setting. We hypothesized that those patients with CN who presented with a Charcot-related foot wound would have lower rates of successful limb salvage than patients who presented without a wound. METHODS: Two hundred forty-five patients (280 feet) were identified with diabetic CN during the time period from January 1, 2005, to June 1, 2015...

Ghost cell tumors are a family of lesions that range in presentation from cyst to solid neoplasm and in behavior from benign to locally aggressive or metastatic. All are characterized by the presence of ameloblastic epithelium, ghost cells, and calcifications. This report presents the cases of a 14-year-old girl with a calcifying cystic odontogenic tumor (CCOT) and a 65-year-old woman with a peripheral dentinogenic ghost cell tumor (DGCT) with dysplastic changes, a rare locally invasive tumor of odontogenic epithelium...

BACKGROUND: The most common sequelae after surgical removal of mandibular third molar are pain, trismus, swelling, and dysphagia. However, these symptoms can also signal the onset of surgical site infection and alveoli osteitis. The aim of this study was to evaluate the efficacy of prophylactic amoxicillin/clavulanic acid and levofloxacin and preemptive therapy of amoxicillin/clavulanic acid in the reduction of postinflammatory complications, surgical site infection, and alveolar osteitis following the third molar surgery...

PURPOSE: The antimetabolite drug, 5-fluorouracil (5-FU), is used in the treatment of various cancers, including basal cell carcinomas (BCCs). The authors hypothesized that keratocystic odontogenic tumors (KOTs) would respond to 5-FU treatment because of their similarities to BCCs in molecular etiopathogenesis. MATERIALS AND METHODS: An ambispective cohort study of the treatment efficacy of topical 5-FU on KOTs was conducted. Independent variables included the topical application of 5% 5-FU or modified Carnoy solution (MC) after enucleation and peripheral ostectomy at the University of Toronto from 2006 through 2014...

OBJECTIVES: To evaluate the effect of varying the number and configuration of locking bicortical and monocortical screws on a plate-rod construct using a mid-diaphyseal femoral ostectomy model. METHODS: Thirty Greyhound femurs were assigned to six groups (A-F). An intramedullary pin was placed in each bone following which a 3.5 mm locking plate was applied with six differing locking screw configurations. Groups A to C had one bicortical screw in the most proximal and distal plate holes and one to three monocortical locking screws in the proximal and distal fragments...

The use of tissue-engineered bone constructs is an appealing strategy to overcome drawbacks of autografts for the treatment of massive bone defects. As a model organism, the mouse has already been widely used in bone-related research. Large diaphyseal bone defect models in mice, however, are sparse and often use bone fixation which fills the bone marrow cavity and does not provide optimal mechanical stability. The objectives of the current study were to develop a critical-size, segmental, femoral defect in nude mice...

PURPOSE: Resections in the posterior component of the oral cavity usually lead to severe functional compromise and lower quality of life for patients. Notable advances in reconstruction of the posterior part of the mouth and of the oropharynx have occurred in recent decades. The anatomic and physiologic rehabilitation of the defect to a reasonable outcome with low morbidity and mortality remains the founding basis of any surgical reconstruction, which also holds true for oral oropharyngeal and retromaxillary reconstructions...

Factors associated with the diagnosis, aetiology, and treatment of mandibular fractures occurring during the postoperative period following the removal of a lower third molar are discussed. The following databases were searched using specific key words: PubMed/MEDLINE, LILACS, Embase, and Scopus. The search yielded 124 cases. Sex, age, side, tooth position and angulation, bone impaction, relationship between the tooth and the inferior alveolar nerve, local pathological conditions, aetiology of the fracture, symptomatology, and time between surgery and fracture, as well as any displacement of the fracture and the treatment of the fracture, were evaluated...

PURPOSE: Orthognathic surgery is an efficient procedure for cosmetic and functional aims. However, when functional improvement is achieved by mandibular or maxillary operations, additional esthetic corrections may be imperative for some patients. This study aims to introduce our primary practice of simultaneous facial bone contouring and orthognathic surgery for esthetic reasons. PATIENTS AND METHODS: Ten patients with dentofacial deformities as well as a prominent angle, asymmetric deformities, or a high zygoma and zygomatic arch were recruited from West China Hospital of Stomatology, Sichuan University (Chengdu, China), between January 1, 2014, and July 31, 2015...

BACKGROUND: Reduction malarplasty to correct prominent malar complex is popular in Asians. Despite the popularity of reduction malarplasty, most of the surgical methods applied are not selected according to the degree of zygoma protrusion. In this study, we analyzed the effectiveness of two different surgical procedures to clarify their appropriateness for each zygoma type. METHODS: One of the procedures used was the "bidirectional wedge ostectomy," in which a bidirectional wedge-shaped bone fragment was removed from the zygomatic body via oral incision and oblique complete osteotomy of the zygomatic arch via sideburn incision...

Costochondral grafts are used to replace the mandibular condyle in cases of TMJ ankylosis, and are generally viewed as a gold standard for autogenous reconstruction of the mandibular condyle (Güven, 2000; Posnick and Goldstein, 1993 [1,2]). We report a case where overgrowth of costochondral grafts is seen, resulting in asymmetric mandibular growth and dentofacial asymmetry (Posnick and Goldstein, 1993 [2]). A 17 year old male patient presented with an existing costochondral graft performed due to TMJ ankylosis during childhood...

OBJECTIVE: To verify the ability of a novel Canine Elbow Realignment Osteotomy (CERO) system for acute axial radial or ulnar lengthening to restore normal elbow congruency in a shortened radius cadaver model using assessment by computed tomography (CT). STUDY DESIGN: In vitro cadaver study. ANIMALS: Five pairs of greyhound forelimbs from animals euthanatized for reasons unrelated to the study. METHODS: CT of each elbow was performed (1) pre-operatively (pre-op), (2) after placement of a linear motor IMEX™ external skeletal fixator (ESF) on the radius with diaphyseal ostectomy and radial shorting of 1-5 mm (post-ESF), and (3) after CERO surgery to lengthen the radius proximal to the ostectomy site by an amount equal to the degree of radial shortening (post-CERO)...

A five month old Brown Swiss heifer calf (212 kg body mass) with severe left hind limb lameness, caused by a wound of the lateral digit was referred to the veterinary teaching hospital. The calf showed a score 4 of 5 lameness on the left hind limb. A scarified skin lesion with a fistula formation and purulent exudate was observed at the level of the proximal interphalangeal joint (PIJ) of the lateral digit of the left hind. The PIJ region and the lateral digit were severely swollen and painful. Ultrasonography showed a moderate anechoic effusion of the lateral digital flexor tendon sheet (DFTS) and a severe heterogeneous hypoechoic effusion with some small hyperechoic areas of the plantar and dorsal pouch of the PIJ...

Odontogenic fibromyxoma (OFM) is a benign, locally invasive and aggressive nonmetastasizing neoplasm of jaw bones. They are considered relatively rare and known to be derived from embryonic mesenchymal elements of dental origin. Treatment of OFM depends on the size of the lesion and on its nature and behavior. Varying treatment modalities ranging from curettage to radical excision have been documented. Aim; This paper is a review of management of 8 pediatric patients with histologically diagnosed OFM at a Nigerian tertiary health care facility...
