BACKGROUND: Dissecting aneurysms of the basilar artery (BA) are rare lesions and the management of them has been controversial and challenging. The treatment becomes much more difficult when the patient has a disorder such as aortitis syndrome, which makes cerebral arteries occluded and tortuous. The authors describe a case of a ruptured BA dissecting aneurysm associated with aortitis syndrome, successfully treated with hybrid neurovascular surgery. CASE DESCRIPTION: A 64-year-old woman with a medical history of aortitis syndrome developed a severe headache and was diagnosed with a subarachnoid hemorrhage from a BA dissecting aneurysm...

BACKGROUND: Neurovascular-compression syndrome (NCS) is described as a prominent pathological contact between cranial nerves and vessels. Trigeminal neuralgia, hemifacial spasm, and glossopharyngeal neuralgia are typical clinical entities associated with NCS. On the other hand, the hyoglossal nerve is rarely affected by NCS. CASE DESCRIPTION: We present a case of hypoglossal nerve palsy (HNP) secondary to vertebral artery (VA) compression. A 47-year-old man presented to our hospital with a 1-month history of dysarthria and dysphagia...

Posterior knee approaches are reliable techniques to address the treatment of various pathologies of the posterior region of the knee, including Baker cyst excision, tibial plateau fracture fixation, posterior cruciate ligament avulsions and inlay reconstructions, femoral condyle cartilage procedures, posterior meniscal repair and loose body removal among others. Surgery in the posterior knee region can be challenging because of the presence of neurovascular structures including the tibial nerve, popliteal artery and vein, and common peroneal nerve; thus, it is less commonly performed...

Late stage ankle osteoarthritis often presents with debilitating pain. It is common to find osteophytes and loose body formation around the joint. Total ankle arthroplasty can preserve joint mobility and pain relieve for such patient. However, when trying to remove the osteophytes and loose bodies at the posterior ankle joint, there is risk of damaging posterior structures such as the neurovascular bundle during the procedure. We are presenting a case where the posterior loose bodies remained untouched during the operation, and patient showed spontaneous resolution of the lesions with time...

PURPOSE: To preserve the joint structure in order to maintain good limb function in patients with osteosarcoma, we perform epiphyseal or metaphyseal osteotomy and reconstruction using frozen autografts that contain a tumour treated with liquid nitrogen. There are two methods of using liquid nitrogen-treated autografts: the free-freezing method and the pedicle-freezing method. The purpose of this study was to evaluate the results of intentional joint-preserving reconstruction using the free-freezing method and the pedicle-freezing method in patients with osteosarcoma...

INTRODUCTION: Microvascular decompression (MVD) is accepted as the only aetiological surgical treatment for refractory classic trigeminal neuralgia (TN). There is therefore increasing interest in establishing the diagnostic and prognostic value of identifying neurovascular compressions (NVC) using preoperative high-resolution three-dimensional magnetic resonance (MRI) in patients with classic TN who are candidates for surgery. METHODS: This observational study includes a series of 74 consecutive patients with classic TN treated with MVD...

Carotid body tumours are rare and mostly benign neoplasm. They are slow growing but can evade or exert pressure on neighbouring important neurovascular structures. Hence, surgical resection remains the treatment modality of choice for large tumours partially or completely encasing the carotid arteries. But the surgical resection of these tumours with minimum morbidity is challenging because of their highly vascular nature. Earlier literature has dealt with various aspects of management of carotid body tumours including classification, morbidity, work-up, embolisation and extent of resection...

Well-differentiated liposarcomas of the extremities are one of the most frequent types of malignant soft tissue tumors in adults. These tumors are typically locally aggressive and show a tendency to recurrence after surgical excision even though they do not metastasize and very rarely dedifferentiate. Its clinical presentation is generally a progressively growing mass causing aesthetic, functional, or compressive symptoms depending on the tumor's size and localization. Several authors recommend a wide excision with free margins in order to minimize the risk of recurrence, while others report good results and a low rate of recurrence with more conservative or even marginal excision thereby avoiding complications due to surgical site morbidity...

PURPOSE: Posterior elbow impingement can cause disabling pain and limited motion during activities involving elbow extension. Less understood is whether arthroscopic treatment, compared to open surgery, can result in effective management of pain, loss of range of motion, and return athletes to previous levels of activity. This study determined whether arthroscopic debridement is a safe and effective treatment for posterior elbow impingement and whether it enables athletes to return to a previous level of function...

OBJECTIVE: Intracranial meningiomas are typically benign extracerebral tumors derived from dural arachnoid cells. Predominantly, these tumors are effectively managed surgically, but the prognosis is heavily dependent on tumors' histological heterogeneity and its location. It is known that reproductive and hormonal factors increase the risk for meningioma in adult females, but their prognostic value still remains controversial. This study's aim was to examine possible correlation between tumor location and outcome, and to evaluate prognostic value of the proposed simple tumor localization scale in predicting the management outcome of intracranial meningioma...

BACKGROUD: Anterior cervical discectomy and fusion (ACDF) with plate-screw construct has been gradually applied for multilevel cervical spondylotic myelopathy (CSM) in recent years. However, long cervical plate was associated with complications including breakage or loosening of plate and screws, trachea-esophageal injury, neurovascular injury, and postoperative dysphagia. To reduce these complications, the zero-profile spacer has been introduced. This meta-analysis was performed to compared the clinical and radiological outcomes of zero-profile spacer versus cage-plate construct for the treatment of multilevel cervical spondylotic myelopathy...

This report presents the first case of a knee dislocation following septic arthritis after arthroscopy. A 65-year-old woman had an arthroscopy with irrigation and debridement (I&D) of the joint and microfracture for the chondral lesions. She had complaints of postarthroscopic infection but non-steroidal anti-inflammatory medication and local ice compression was recommended. She revisited her physician twice and at the last visit she had a large purulent effusion in her knee. The gram stain of the joint fluid aspirate demonstrated gram-positive cocci and the cultures grew methicilline-sensitive Staphylococcus aureus...

OBJECTIVE Approximately 75%-92% of patients with trigeminal neuralgia (TN) achieve pain relief after Gamma Knife surgery (GKS), although a proportion of these patients will experience recurrence of their pain. To evaluate the reasons for durability or recurrence, this study determined the impact of trigeminal nerve length and volume, the nerve dose-volume relationship, and the presence of neurovascular compression (NVC) on pain outcomes after GKS for TN. METHODS Fifty-eight patients with 60 symptomatic nerves underwent GKS for TN between 2013 and 2015, including 15 symptomatic nerves secondary to multiple sclerosis (MS)...

Exosomes are gaining importance because they show great promise in therapeutic applications for several diseases. Particularly in stroke, exosomes derived from mesenchymal stem cell (MSC) therapy work as paracrine effectors responsible for promoting neurovascular remodeling and functional recovery. Adult male rats were subjected to intracerebral hemorrhage (ICH) by intrastriatal injection of collagenase type IV; 24 h after surgery, MSC-derived exosomes were administered through the tail vein. The rats were euthanized at 7 or 28 days after treatment...

BACKGROUND: Intraoperative angiography is routinely utilized for aneurysms and arteriovenous malformations (AVMs) to verify complete occlusion and resection. Surgery for spinal and posterior fossa neurovascular lesions is usually performed in prone position. Intraoperative angiography in the prone position is challenging and there is no standardized protocol for this procedure. OBJECTIVE: To describe our experience with intraoperative angiography in the prone and lateral positions, using upper extremity arterial access...

BACKGROUND: Fractures in the posterior aspect of the medial malleolus form an important subset of ankle fractures and the indications for fixation include involvement of > 25% of the articular surface or an articular step off by > 2mm. Several approaches have been described but there has been no recent study on the direct medial approach. METHODS: Five fresh frozen cadaveric ankles were dissected using the direct medial approach. A longitudinal incision of 10cm was centered directly over the medial malleolus and deepened straight down to the bone...
