BACKGROUND: Outcomes following revision surgery for scaphoid nonunions with osteonecrosis are guarded. We hypothesized that use of free vascularized medial femoral condyle (MFC) bone grafts can lead to healing of the nonunion, increase vascularity of the proximal pole, and restore scaphoid architecture, resulting in acceptable functional outcomes. METHODS: We performed a retrospective review of 49 patients who were treated with an MFC bone graft, between May 2005 and September 2016, after prior failure of operative treatment for scaphoid nonunion...

Current animal models of chronic peripheral nerve compression are mainly silicone tube models. However, the cross section of the rat sciatic nerve is not a perfect circle, and there are differences in the diameter of the sciatic nerve due to individual differences. The use of a silicone tube with a uniform internal diameter may not provide a reliable and consistent model. We have established a chronic sciatic nerve compression model that can induce demyelination of the sciatic nerve and lead to atrophy of skeletal muscle...

BACKGROUND AND PURPOSE: Extracranial internal carotid artery (ICA) dissection is an important cause of ischemic stroke in younger adults. The optimal medical and surgical strategies for managing these lesions have not been well established. We report a case series of extracranial ICA reconstruction using overlapping flow-diverter stents as a rescue therapy for the treatment of symptomatic ICA dissection in patients presenting with recurrent ischemic stroke and/or severe hemispheric hypoperfusion who failed medical management...

Embolization of systemic to pulmonary artery collaterals to regulate pulmonary arterial flow or pressure of the cavopulmonary circulation in patients with single ventricle is a common practice. The relative incidence and impact of this practice on future interventions like coronary artery bypass grafting is poorly understood. This study aims to evaluate the frequency and implications of internal mammary artery (IMA) embolization in the single ventricle (SV) population. A retrospective chart review was performed of SV patients who underwent cardiac catheterization before and after Fontan procedure between February 2007 and 2017...

Background: The majority of patients develop posttraumatic osteoarthritis within 15 years of anterior cruciate ligament (ACL) injury. Inflammatory and chondrodegenerative biomarkers have been associated with both pain and the progression of osteoarthritis; however, it remains unclear if preoperative biomarkers differ for patients with inferior postoperative outcomes. Hypothesis/Purpose: The purpose of this pilot study was to compare biomarkers collected on the day of ACL reconstruction between patients with "good" or "poor" 2-year postoperative outcomes...

Background: Tibia vara, or Blount's disease, is a pathologic angular deformity of upper tibial physis causing a bow leg deformity. Adolescent Blount's disease may be unilateral or bilateral and is diagnosed during or just before the adolescent growth spurt. In addition to predisposing genetic factors, biomechanical overload of the proximal tibial physis causes asymmetric growth leading to a varus deformity.Surgical intervention is usually required for adolescent Blount's disease. Hemiepiphysiodesis has had some success in arresting or correcting the deformity...

Recent estimates suggest an annual incidence of greater than 125,000 femoral neck fractures. Surgical treatment is indicated for the majority of these fractures, which are estimated to double by the year 2050. Most displaced femoral neck fractures in elderly patients are treated with arthroplasty secondary to high complication rates associated with internal fixation. Traditional implants used for internal fixation, typically in elderly patients with stable fracture morphology and younger patients regardless of morphology, include the sliding hip screw (SHS), with or without a supplemental anti-rotation screw, and multiple cancellous lag screws...

BACKGROUND: The treatment of radial neck fractures is controversial and typically depends on displacement. Surgical procedures based on open reduction-internal fixation (ORIF) may lead to several complications, such as avascular necrosis of the radial head, nonunion, malunion, and elbow stiffness. Closed reduction with intramedullary pinning of radial neck fractures, which is commonly used in children, is a viable option for these fractures in adults and may allow for a lower complication rate compared with ORIF...

PURPOSE: Effective operative approaches for the treatment of refractory vertigo in Meniere's disease are invasive. Vestibular neurectomy can preserve hearing and has been shown to be effective; however, current approaches require an extensive craniotomy. Transcanal endoscopic approaches to the internal auditory canal (IAC) with cochlear preservation have been recently described and may offer a minimally invasive approach to selectively sectioning the distal vestibular nerves while preserving residual hearing...

PURPOSE: Idiopathic condylar resorption (ICR) is a relatively uncommon condition. Its diagnosis, etiology, and management options are controversial. Furthermore, it is difficult for 1 provider to collect a large cohort of ICR patients to develop a statistically significant study of these concerns. Therefore, the purpose of this study was to survey experienced temporomandibular joint (TMJ) surgeons who have managed ICR cases relative to these concerns, as well as review the management outcome literature...

BACKGROUND: Short-stay units are hospital units that provide short-term care for selected patients. Studies have indicated that short-stay units might reduce admission rates, time of hospital stays, hospital readmissions and expenditure without compromising the quality of care. Short-stay units are often defined by a target patient category, a target function, and a target time frame. Hypothetically, short-stay units could be established as part of any department, but this review focuses on short-stay units that provide care for participants with internal medicine diseases and conditions...

Varus derotation femoral osteotomy (VDFO) is a commonly used surgical procedure in association with pelvic osteotomy for dislocated hip in developmental hip dysplasia. Several types of internal fixation devices were described in the literature, but none of them showed a superiority or a lower rate of complication over the others. Different types of external fixator were also described for proximal osteotomy fixation with good results. We describe the surgical technique of the VDFO using a modular external fixator with an illustrative case...

Traditionally, ruptured hepatoblastoma is considered a high-risk occurrence, necessitating a chemotherapy regimen usually consisting of cisplatin alternating with carboplatin plus doxorubicin, based on International Childhood Liver Tumours Strategy Group studies. However, ruptured hepatoblastomas with intact hepatic capsules may represent a unique subgroup that may be successfully treated with TAE, cisplatin monotherapy, and surgical excision. We herein present a case of ruptured hepatoblastoma (pretreatment tumor extension stage II) in a 1-year-old female patient that was successfully managed with transarterial embolization (TAE), eight courses of cisplatin chemotherapy and surgical removal...

The International Otology Outcome Group (IOOG) was founded in 2017 to encourage and facilitate international collaboration with regard to the surgical outcome of ear surgery. This report outlines the methodology and recommendations of the consensus-based categorization of tympanomastoid surgery produced by the IOOG. The IOOG Steering Committee used the acronym SAMEO-ATO to categorize tympanomastoid operations, representing the stage of surgery, approach, mastoid bone extirpation, external bony wall repair, obliteration of the mastoid cavity, access to the middle ear, tympanic membrane reconstruction, and ossicular reconstruction...
