Methods: All patients that underwent neck dissections under the care of OMS at Waikato Hospital between January 2016 and December 2021 were included. Data on patient demographics, diagnosis, surgery details, nodal yields, histological results and clinical outcome were collected retrospectively for analysis.

Two-year continuous data capture using a wearable sensor to remotely monitor the surgical spine patient: a case report.

We report the case of a 46-year-old male with long-standing low back pain who presented with a deterioration of symptoms characterised by back and right leg pain corresponding to the L4 and L5 dermatomes. An MRI scan revealed severe central and lateral recess stenosis at L4/5 secondary to a large central disc protrusion. We remotely monitored activity and general health metrics over a time-period exceeding two years.

Tracking the disease progression of lumbar spinal stenosis using objective gait metrics: a case report.

We present the case of an 85-year-old woman who presented to our clinic with neurogenic claudication due to lumbar spinal stenosis (LSS) over a period of two years. During this time a series of walking metrics were monitored including daily step count, walking speed, and step length. All metrics showed a deterioration over time and objectively document the disease progression of LSS (initial: walking speed =1.

Analysing Gait Patterns in Degenerative Lumbar Spine Disease Using Inertial Wearable Sensors: An Observational Study.

Objective: Using a chest-based inertial wearable sensor, we examined the quantitative gait patterns associated with lumbar disc herniation (LDH), lumbar spinal stenosis (LSS), and chronic mechanical low back pain (CMLBP). 'Pathological gait signatures' were reported as statistically significant group difference (%) from the 'normative' gait values of an age-matched control population.

Methods: A sample of patients presenting to the Prince of Wales Private Hospital (Sydney, Australia) with primary diagnoses of LDH, LSS, or CMLBP were recruited.

Delayed Fragmentation and Distal Embolization of Retained Microcatheter Causing Lower Limb Ischemia: Case Report and Review of the Literature.

Background: Endovascular microcatheter adherence and retention is an uncommon complication during brain arteriovenous malformation (AVM) embolization with glue or ethylene-vinyl alcohol copolymer that has previously reported, although there are sparse reports of symptomatic complications thereafter.

Case Description: We present a unique complication 6 years after initial embolization of a cerebral AVM. The patient presented with acute lower limb insufficiency with computed tomography angiogram revealing fragmentation of the microcatheter and associated popliteal aneurysm.

Outcomes for Vertebrectomy for Malignancy and Correlation to the Spine Instability Neoplastic Score (SINS): a 10-Year Single-Center Perspective.

Objective: The clinical prognostic value of the Spinal Instability Neoplastic Score (SINS), in the context of vertebrectomy for neoplasia, has not yet been established. This retrospective study of 134 patients aims to evaluate the efficacy of the SINS to predict outcomes and survival after vertebrectomy for malignancy.

Methods: The patients were classified into 2 groups: indeterminate stability (SINS 7-12) and unstable (SINS 13-18).

Vertebrectomy in metastatic spinal tumours: A 10 year, single-centre review of outcomes and survival.

Metastatic disease to the vertebral column can cause spinal instability, neurological deterioration and pain. The present study was designed to provide insight into the cohort undergoing vertebrectomy for metastatic disease to the spinal column, assessing the associated morbidity, functional outcomes and survival. A retrospective review of 141 consecutive vertebrectomies for metastatic disease was undertaken.

The role of wearables in spinal posture analysis: a systematic review.

Background: Wearables consist of numerous technologies that are worn on the body and measure parameters such as step count, distance travelled, heart rate and sleep quantity. Recently, various wearable systems have been designed capable of detecting spinal posture and providing live biofeedback when poor posture is sustained. It is hypothesised that long-term use of these wearables may improve spinal posture.

Anterior lumbar interbody fusion (ALIF) as an option for recurrent disc herniations: a systematic review and meta-analysis.

Background: Recurrent intervertebral disc herniation is a relatively common occurrence after primary discectomy for lumbar intervertebral disc herniation. For recurrent herniations after repeat discectomies, a growing body of evidence suggests that fusion is effective in appropriately selected cases. Theoretically, anterior lumbar interbody fusion (ALIF) allows for comprehensive discectomy, less trauma to spinal nerves and paraspinal muscles and avoidance of the disadvantages of repeat posterior approaches.

Outcomes of Short Fusion versus Long Fusion for Adult Degenerative Scoliosis: A Systematic Review and Meta-analysis.

The objective of this study was to evaluate differences in clinical and radiographic outcomes between short (<3 levels) and long (≥3 levels) fusions in the setting of degenerative lumbar scoliosis. A literature search was performed from six electronic databases. The key terms of "degenerative scoliosis" OR "lumbar scoliosis" AND "fusion" were combined and used as MeSH subheadings.

Intraoperative navigation for accurate midline placement of anterior lumbar interbody fusion and total disc replacement prosthesis.

Anterior lumbar approach techniques for the management of discogenic back pain and placement of spinal instrumentation such as fusion and disc replacement prosthesis is becoming increasingly popular. To date, no studies have reported the clinical usage of spinal navigation with anterior lumber interbody fusion (ALIF) and total disk replacement (TDR). We describe a surgical procedure of a 35-year-old patient presenting with discogenic lower back pain treated with an anterior lumbar interbody fusion and total disc replacement procedure to highlight the clinical advantages of intraoperative CT spinal navigation for accurate implant placement, therefore optimising peri- and post-operative outcomes.

Subsidence following anterior lumbar interbody fusion (ALIF): a prospective study.

Background: Anterior lumbar interbody fusion (ALIF) is a widely used surgical technique for disorders of the lumbar spine. One potential complication is the subsidence of disc height in the post-operative period. Few studies have reported the rate of subsidence in ALIF surgery prospectively.

Spontaneous regression of post-traumatic syringomyelia: A case report and literature review.

Syringomyelia defines a condition in which myelopathy develops secondary to the formation of a cyst or cavity within the spinal cord parenchyma known as a syrinx. Although there is a significant volume of studies analysing the underlying mechanisms behind their formation, the management of such cavities remains an ongoing topic of debate. Aside from conservative approach, a range of surgical options exist, however long term outcomes are poor and a literature search reveals that the overall benefits are questionable.

Gliomatosis cerebri: Prognosis based on current molecular markers.

This study aims to review the literature and identify key molecular markers affecting the prognosis of Gliomatosis cerebri (2) to evaluate the level of evidence and identify outstanding markers requiring further study. A literature search was conducted across 5 major databases using the key terms: "Molecular markers" AND "Gliomatosis cerebri" OR "diffuse astrocytoma." Critical appraisal and data presentation was performed inline with the PRISMA guidelines.

Anterior Lumbar Interbody Fusion in Left-sided Inferior Vena Cava and Right-sided Aortic Arch.

Spinal fusion via anterior lumbar interbody fusion (ALIF) can offer symptomatic relief to patients that suffer severe low back pain, radiculopathy, and claudication. However, a detailed working knowledge of the thoracic, abdominal, and lumbar anatomy, particularly of the vasculature, is vital. We report the case of a 68-year-old man who presented with radiculopathy and progressively worsening low back pain despite 9 months of unsuccessful conservative therapy and pain management.

Application of a 3D custom printed patient specific spinal implant for C1/2 arthrodesis.

The study aims to describe a three-dimensional printed (3DP) posterior fixation implant used for C1/C2 fusion in a 65-year-old female. Spinal fusion remains a common intervention for a range of spinal pathologies including degenerative disc and facet disease when conservative methods are unsuccessful. However, fusion devices are not always entirely efficacious in providing the desired fixation, and surgeons rely on 'off the shelf' implants which may not provide an anatomical fit to address the particular pathology.

Surfer's myelopathy: a rare presentation in a non-surfing setting and review of the literature.

Background: Surfers myelopathy can be a rapidly devastating disease and little is known surrounding the pathophysiology of the condition. Although the classical pattern of illness has been well reported, it has never been observed in a non-surfing setting.

Methods: A 51-year-old demolition worker presented with acute non-traumatic myelopathy.

Anterior cervical discectomy and fusion (ACDF) autograft versus graft substitutes: what do patients prefer?-A clinical study.

Background: Patient dissatisfaction with donor site morbidity has led to the search for alternative grafting options and techniques. This report compares patient satisfaction rates between autograft and graft substitutes for anterior cervical discectomy and fusion (ACDF).

Methods: This study was performed with the approval of the local area health network ethics committee.

Anterior cervical disc arthroplasty (ACDA) versus anterior cervical discectomy and fusion (ACDF): a systematic review and meta-analysis.

Background: Surgical approaches are usually required in cases of severe cervical disc disease. The traditional method of anterior cervical disc fusion (ACDF) has been associated with reduced local mobility and increased occurrence of adjacent segment disease. The newer method of anterior cervical disc arthroplasty (ACDA) relies upon artificial discs of various products.

Intraneural Ganglion Cyst of the Ulnar Nerve at the Elbow Masquerading as a Malignant Peripheral Nerve Sheath Tumor.

Background: Ulnar neuropathy at the elbow (UNE) is the second most common mononeuropathy of the upper extremity. One rare cause of UNE is nerve mass lesions, including intraneural ganglion cysts (IGCs). IGC imaging studies provide important information that may determine the nature of a peripheral nerve mass lesion.

Histological analysis of surgical samples and a proposed scoring system for infections in intervertebral discs.

Back pain remains one the most prevalent types of pain and disability worldwide. Infection is estimated to be the underlying cause in approximately 0.01% of patients.

The role of specialist units to provide focused care and complication avoidance following traumatic spinal cord injury: a systematic review.

Objective: Current recommendations for traumatic spinal cord injury treatment recommend immediate transfer to a spinal injury unit (SIU) where available following patient stabilisation. Although transfer is dependent on a variety of factors, the largest review was unable to justify implementation of such units on the basis of insufficient and lack of quality data in favour of care at the SIU as opposed to non-SIU centres. Our study sought to investigate: are subspecialty spinal injury units (SIUs) able to provide superior care compared with traditional trauma/rehab units? Is the standard of care of acute spinal cord injured patients to be managed in SIU's?

Method: A literature search was conducted across five major databases using the key terms: "spinal cord injury" AND "Spinal Injury Unit" OR "spinal rehabilitation" OR "spinal injury centre" OR "specialist care" OR "care requirements.

Accelerometers for objective evaluation of physical activity following spine surgery.

With the potential of bias from subjective evaluation scores in spine surgery, there is a need for practical and accurate quantitative methods of analysing patient recovery. In recent years, technologies such as accelerometers and global positioning systems have been introduced as potential objective measures for pain and symptoms following spine surgery. Overall, this perspective article aims to discuss and critique currently utilised methods of monitoring spine surgical outcomes.

Unilateral Hemilaminectomy for Intradural Lesions.

Objective: Unilateral hemilaminectomy (UHIL), an alternative surgical approach to intradural lesions, involves a unilateral approach to meningeal opening that provides an adequate window for tumor extraction while leaving most of the vertebral structures intact. The techniques and results of a modified hemilaminectomy technique with spinal endoscopy is discussed and limited unilateral hemilaminectomy for intradural tumors (UHIT) evaluated prospectively.

Methods: Relevant clinical variables, operative reports, histological findings, pre- and post-operative imaging, and follow-up data for 11 consecutive patients (five males, six females; mean age 63.
