Head and neck continued: a retrospective analysis of neck dissections from a New Zealand oral and maxillofacial surgery unit.

AIMS: The aim of this study is to analyse the demographics, diagnosis, nodal yield, metastatic rates and outcomes of patients undergoing neck dissections within the Waikato Hospital Oral and Maxillofacial Surgery (OMS) Department. 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. RESULTS: One hundred and five patients and 123 neck dissections were included in the final analysis. The median age was 65 years of age. The average nodal yield from a selective neck dissection of levels I-III was 20.1 and I-IV was 25.4. There was no metastatic nodal disease in level IIb, and only 2 neck dissections with nodal disease in level IV. Complications were mostly associated with free flap reconstruction rather than the neck dissection alone. CONCLUSIONS: The demographics and outcomes of the study cohort are consistent with both the current population and previously published head and neck data. The OMS unit at Waikato Hospital recommends omission of levels IIb and IV in neck dissections for cN0 cases if deemed oncologically safe to do so.

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 =1.03 m/s, step length =0.49 m, and daily step count =3,136; final: walking speed =0.49 m/s, step length =0.37 m, and daily step count =334). At this time, the patient had also begun experiencing bilateral lower limb weakness and paraesthesia upon exertion, preventing her from mobilizing for more than a few meters at a time. After a shared decision-making process with the patient and her family, surgical management was recommended. The deterioration of the patient's walking metrics matched their increasing requirement for walking assistance, with no walking assistance being needed initially, compared to a four-wheel walker being required in the weeks prior to her surgery. Therefore, the extent of walking deterioration may be able to inform clinical decision-making regarding appropriate walking assistance. To our knowledge, this is the first report that objectively documents the deterioration of LSS using walking metrics for such a prolonged duration of time.

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. This is the first study to monitor these metrics remotely and continuously in the surgical spine patient. Over this time, he received several interventions including a spinal cord stimulator implant, and an L4/5 microdiscectomy. We tracked his fluctuating health status using the Oura Ring [objectively measuring metrics including step count, sleep patterns, heart rate (HR), heart-rate variability (HRV), and respiratory rate (RR)] and with daily self-reported scores on the Visual Analogue Scale. The Oura Ring is a convenient and lightweight wearable device that is worn on any finger. Taken together, metrics provided a comprehensive picture of deterioration and recovery, paralleling key events in the patient's history. The use of wearable devices is feasible in enabling long-term remote continuous monitoring. This may assist surgeons and rehabilitation providers in identifying early deterioration and monitoring the post-intervention course of recovery.

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. The patient underwent an emergency grafting and removal of the retained fragment and recovered without deficit postoperatively. CONCLUSIONS: Fragmentation over retained microcatheters remains a concern that may be worth monitoring in the long term, although there are no recommendations for timing.

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). Outcomes assessed included survival days after procedure, neurological function (modified Frankel grade), operative time, blood loss, complications, construct failure, and length of inpatient stay. RESULTS: The indeterminate group included 68 patients, whereas the unstable group included 66 patients. No patients were classified as stable (SINS 0-6). The median survival was 225 days (interquartile range, 81-522 days). There was a statistically significant difference (P < 0.001) in survival days after vertebrectomy between the indeterminate group (435 days) and the unstable group (126 days). The majority of patients (119) had a favourable Frankel grade after procedure with no significant difference between SINS groups (P = 0.534). There were no differences in the operative time (234 vs. 210; P = 0.130), inpatient hospital length of stay (10 days vs. 11 days; P = 0.152), complications, or need for intensive care admission (intensive care unit) between the 2 cohorts. There was a statistically significant difference (P = 0.006) for intraoperative blood loss between the indeterminate group (1400 mL) and the unstable group (850 mL). CONCLUSIONS: This study demonstrates a statistically significant increased survival in the indeterminate cohort. These results demonstrate the potential ability of the SINS to act as a clinical prognostic tool with regard to survival time.

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 procedures were performed between 2006 and 2016 at a single institution. Medical records were reviewed and data was obtained regarding primary malignancy, presenting symptoms, pre-operative chemotherapy or radiotherapy, Spinal Instability Neoplastic Score, neurological function, operative approach and duration, blood loss, transfusion requirement, complications, survival, delayed neurological deterioration and construct failure. Long-term follow-up data was available for 123 patients. Forty-two patients were alive at the time of review with a mean survival of 464 days. Post-operative neurological function was preserved or improved in 96.5% of patients. Five patients suffered a neurological deterioration post-operatively. The major complication rate was 19.8% with the most frequent complication being wound infection or dehiscence requiring revision. There were four inpatient deaths. Mean operative time was 240 min. Mean blood loss was 1490 mls. When assessing results by age, no significant difference with respect to complications, neurological outcomes or survival was demonstrated in patients over age 65. There was a significant reduction in survival and higher complication rates in patients who were non-ambulatory following vertebrectomy. Vertebrectomy is a safe and effective means of providing circumferential neural decompression and stabilization with an acceptable complication rate in patients with vertebral metastases, irrespective of age.

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. RESEARCH QUESTIONS: To (1) examine the capabilities of current devices assessing spine posture, (2) to identify studies implementing such devices in the clinical setting and (3) comment on the clinical practicality of integration of such devices into routine care where appropriate. METHODS: A comprehensive systematic review was conducted in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Guidelines (PRISMA) across the following databases: PubMed; MEDLINE; EMBASE; Cochrane; and Scopus. Articles related to wearables systems able to measure spinal posture were selected amongst all published studies dated from 1980 onwards. Extracted data was collected as per a predetermined checklist including device types, study objectives, findings and limitations. RESULTS: A total of 37 articles were extensively reviewed and analysed in the final review. The proposed wearables most commonly used Inertial Measurement Units (IMUs) as the underlying technology. Wearables measuring spinal posture have been proposed to be used in the following settings: post-operative rehabilitation; treatment of musculoskeletal disorders; diagnosis of pathological spinal posture; monitoring of progression of Parkinson's Disease; detection of falls; workplace occupational health and safety; comparison of interventions. CONCLUSIONS: This is the first and only study to specifically review wearable devices that monitor spinal posture. Our findings suggest that currently available devices are capable of assessing spinal posture with good accuracy in the clinical setting. However, further validation regarding the long-term use of these technologies and improvements regarding practicality is required for commercialisation.

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. From relevant studies identified, demographic data, complication rates, Oswestry Disability Index (ODI), and radiographic parameters were extracted and the data was pooled and analyzed. Long fusion was associated with comparable overall complication rates to short fusion (17% vs 14%, P = 0.20). There was a significant difference in the incidence of pulmonary complications when comparing short versus long fusion (0.42% vs 2.70%; P = 0.02). No significant difference was found in terms of motor, sensory complications, infections, construct-related or cardiac complications, pseudoarthrosis, dural tears, cerebrospinal fluid (CSF) leak, or urinary retention. A longer fusion was associated with a greater reduction in coronal Cobb angle and increases in lumbar lordosis, but both findings failed to achieve statistical significance. The ODI was comparable across both cohorts. If shorter fusion lengths are clinically indicated, they should be used instead of longer fusion lengths to reduce perioperative time, costs, and some other complications. However, there are no statistically significant differences in terms of radiographically measurable restoration associated with a short or long fusion.

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. We prospectively evaluated the rate of subsidence in adult patients undergoing ALIF. METHODS: Results were obtained by reviewing scans of 147 patients. Disc heights were measured on radiographic scans taken pre-operatively in addition to post-operatively immediately, at 6 weeks and at 18 months. The anterior and posterior intervertebral disc heights were measured. Subsidence was defined as greater than or equal to 2 mm loss of height. RESULTS: A total of 15 patients (10.2%) had subsidence, with 7 being male. Each case was of delayed cage subsidence (DCS) >6 weeks postoperatively. The mean subsidence was 4.7 mm (range, 2.4-7.8). Mean anterior disc height was 8.6±0.4 mm preoperatively, which improved to 15.1±0.5 mm at latest follow-up. Mean posterior disc height was 4.7±0.2 mm preoperatively, which improved to 8.7±0.4 mm at latest follow-up. The mean lumbar lordosis (LL) angle was 42.5°±10.8° and the mean local disc angle (LDA) was 6.7°±4.0°. The 91.2% (n=114/125) of patients with appropriate radiological follow-up demonstrated fusion by latest follow-up. There was no correlation between subsidence rate with patient reported outcomes [Visual Analog Scale (VAS), Oswestry Disability Index (ODI) and Short Form 12 Item survey (SF-12)] and fusion rates. There was a significant negative correlation between LL and extent of subsidence (Pearson correlation =-0.754, P=0.012). CONCLUSIONS: In conclusion, we found that the subsidence rate at follow-up was generally low following standalone ALIF for this patient series. Patient clinical outcomes and bony fusion rates were not significantly influenced by subsidence.

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.

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. We present a 31-year-old man with an incidental finding of a syrinx on MRI following a traumatic spinal cord injury. Following a decompression and 360° fusion at the C6/7 level for a fracture-dislocation, the patient developed a delayed syrinx (54mm×11mm×8mm), and was managed conservatively. Over 2-year follow-up, the volume of the syrinx spontaneously reduced (46×5×5). Conservative treatment including careful observation is advisable as the first line therapy in patients with a post-traumatic syrinx. Surgery may be indicated in patients with progressive neurological symptoms, however there is a distinct lack of robust evidence on the long-term efficacy of surgery.

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. Following search strategy implementation, 11 studies were included in the final review process. Our data demonstrates significant prognostic value associated with IDH1132H mutation and variable evidence surrounding the role of INA expression, MGMT promoter methylation and other factors. However, there are significant limitations in the level of evidence obtained. As the genetic basis for the pathogenesis of Gliomatosis cerebri continues to widen, there is little data on markers aside from IDH1 mutation available. IDH1132H mutation has been demonstrated to have significant effect on survival, particularly in patients with Gliomatosis cerebri type 2.

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. Preoperative computed tomography and magnetic resonance imaging revealed a rare anatomical variation, with an anomalous left-sided inferior vena cava and anomalous aorta. The patient was surgically treated with ALIF at L4,5 and L5 S1 via an altered surgical window. Given the anomalous anatomy of the patient, instead of performing the procedure after mobilizing both of the transposed abdominal great vessels, the inferior vena cava and the abdominal aorta, the ALIF was uneventfully performed in the window between these vessels. There were no perioperative or postoperative complications. At 12-week postoperative follow-up, X-ray imaging demonstrated successful implantation of ALIF cages with no recurrence of symptoms. A detailed working knowledge of anatomy is important, particularly if anatomical variations are present. This has implications for preoperative surgical planning, which is integral to the safety and the success of procedures.

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. However, ALIF has also been associated with risk of vascular injury and retrograde ejaculation. This current systematic review and meta-analysis aims to assess the viability of ALIF as a surgical treatment for recurrent disc herniations. METHODS: Seven studies were identified from six electronic databases and secondary reference lists. Pre-defined endpoints were extracted from the included studies and meta-analyzed. RESULTS: For the 181 patients from included studies, ALIF resulted in significant average improvements in Oswestry Disability Index (ODI) scores (50.49%, P<0.001), Visual Analogue Scale (VAS) back pain scores (47.85%, P<0.001) and VAS leg pain scores (37.00%, P<0.001). Average blood loss was acceptable at 122 mL (P<0.001) and average operation duration was 89 minutes (P<0.001). Average hospital stay was 5.28 days (P<0.001). Only 22 perioperative complications were reported, with subsidence the most commonly reported complication. CONCLUSIONS: Pooled evidence suggests that ALIF is a feasible approach for the treatment of recurrent disc herniations, demonstrating significant improvements in back and leg pain and minimal complications. These findings warrant further investigation in large prospective registries and multi-center studies.

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. Clinical examination revealed sensory loss to the level of L2. T2-MRI and MRI-DWI revealed a hyperintense signal suggestive of an ischaemic event. A diagnosis of surfer's myelopathy was made and he was commenced on steroid therapy. RESULTS: Following steroid therapy and fluid management the patient was discharged after 6 days with minor anaethesia but significant overall neurological improvement. CONCLUSIONS: Diagnosis of SM requires a thorough history, clinical examination and imaging (MRI, MRI-DWI). The patient should be admitted early and investigated. The use of rehabilitation services may be useful if available.

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. Over a 9-year period, the author performed 574 ACDF procedures (697 levels). Of these, 22 patients had previous surgery with autograft, with a subsequent ACDF procedure performed using a graft substitute. Patients rated their satisfaction with pain, recovery, and preference of autograft versus a bone graft substitute. Graft substitutes used include: tricalcium phosphate/hydroxyapatite (TCP/HA) composite and iFactor placed within a polyetheretherketone (PEEK) cage. RESULTS: Results demonstrated that 21/22 patients achieved a solid fusion with the graft substitute. A total of 20/22 patients rated the autograft incision more painful than the anterior cervical incision, and 21/22 preferred the graft substitute. Three patients had adjacent segment disc replacement performed after autograft/ACDF. All patients reported preference for the total disc replacement (TDR) procedure in terms of recovery and postoperative pain. CONCLUSIONS: Patient satisfaction with bone graft substitutes is very high compared with autograft with all but one (21/22) preferring the graft substitute option. The author questions the traditional recommendation that autograft is the "gold standard" for ACDF. In modern age of graft substitutes, autograft should not be considered the gold standard, but an index option between other options for comparison.

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. CASE DESCRIPTION: We present the case of a 73-year-old woman who presented with rapid deterioration of left hand function over 2 months with weakness of fine motor control, grip strength, and dysesthesia in the ulnar nerve distribution. Preoperative imaging studies, including magnetic resonance imaging (MRI) of the elbow, postcontrast studies, diffusion-weighted imaging, and apparent diffusion coefficient measurements, suggested a highly cellular tumor. Diffusion tensor tractography also revealed imaging features suggestive of a malignant peripheral nerve sheath tumor. During the operation, a sample of the lesion was sent for frozen section. There were no features of malignancy, and the pathologist could not determine a diagnosis based on the tissue sample sent. An intraoperative decision was made not to divide the ulnar nerve above and below the lesion. The IGC was successfully managed by identifying a suitable plane of dissection and cyst resection. CONCLUSIONS: This case demonstrates that MRI studies indicating malignant peripheral nerve sheath tumor must be considered with some caution and corroborated with supportive features on operative inspection and biopsy before radical resection is undertaken. Furthermore, for any nerve mass lesion immediately adjacent to a joint, the differential diagnosis of an IGC should be considered.

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. Despite recent evidence demonstrating prominent infection rates, a standardised algorithm for diagnosis of disc infection is lacking. Histopathological evaluation can aid in confirming inflammatory changes and also in identifying degenerative changes. Hence, standardising practice through a clear scoring system with regards to inflammation and degeneration may have some utility in the clinical setting. To our knowledge no such systems exist specifically for intervertebral disc infection. A literature review of current methods of scoring inflammation and degeneration in spine surgery and orthopaedic surgery was performed. Based on the current evidence, a scoring system for disc inflammatory and degenerative changes was proposed. We propose four domains for consideration: (1) granulation tissue, (2) dense fibrosis, (3) chronic inflammatory cells, and (4) neutrophil count. The non-standardised nature of diagnosing infections and degeneration in the spinal surgery literature means that this scoring system is currently of particular value. Based on a literature review, our proposed method for diagnosis incorporates a combination of histopathological criteria expected to increase diagnostic sensitivity in the setting of disc infection. Overall, scoring can be applied to surgically obtained material and integrated directly into routine pathological practice.

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." RESULTS: After review of over 500 studies, only 9 met inclusion criteria, 3 of which were past reviews. There were no relevant RCT's obtained. Standardised roles of global SIU units are needed to deliver equitable and high quality care as current evidence demonstrates variable standards of care and service (mean LOS range: 16-174 days). There is low quality evidence supporting earlier admission into SIU units being associated with improved neurological outcome, complication rates and reduced LOS, despite variations in the definition of "early admission" across studies. CONCLUSIONS: Our review demonstrates a lack of standardisation within SIU on a global scale, with significantly different outcomes reported across published studies. New and higher quality evidence directly comparing SIU to non-SIU based care is required. Earlier transfer (<24 h) to SIU following initial injury and stabilisation is advised.

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. After analysing current modalities it will briefly analyse new potential methods before examining the place for accelerometers in the field of spine surgery. A literature review was performed on the use of accelerometers for objective evaluation of symptoms and disability after spine surgery, and perspectives are summarised in this article. Physical activity measurement with the use of accelerometers following spine surgery patients is practical and quantitative. The currently available accelerometers have the potential to transform the way functional outcomes from spine surgery are assessed. One key advantage is the collection of standardised objective measurements across studies. Future studies should aim to validate accelerometer data in relation to traditional measures of functional recovery, patient outcomes, and physical activity.
