Use of ultrasonic bone scalpel (UBS) is becoming popular in spinal surgery. This study presents the safety profile of UBS for posterior release in surgical correction of adolescent idiopathic scoliosis (AIS).

From 2016 to 2018, UBS (Misonix) was used by the senior author in a variety of spinal operations. Data for intraoperative complications when this devise was used for posterior correction of AIS were collected. Revision cases were excluded.

UBS was used for posterior release of AIS in 65 patients (58 female, seven male) with an average age of 15.6 years (range 11–23). Average length of posterior instrumentation was 12 levels (range 6–14). Instrumentation was exclusively from T2 to L4. To achieve adequate release for correction, UBS was used to perform a total of 644 modified in-situ chevron osteotomies (average ten, range six to 12) and 31 rib osteotomies. Overall, three complications (4.6 %) were directly related to the use of UBS: one haemopneumothorax, which was successfully treated with a chest drain; and two loss of motor-evoked potentials during monitoring, which led to the postponement of the final correction. These two patients did not have any neurological problems and their surgery was completed successfully within 1 week of the initial surgery. One late deep infection was reported. This was not thought to be directly related to the use of UBS.

Use of UBS in the posterior surgical treatment of AIS appears to be relatively safe with a low level of acceptable complications. However, appropriate training is required for the use of UBS.

Less invasive single-rod fusion technique may be indicated in the management of NMS to minimise operative time, blood loss and wound-related complications. This retrospective 12-year cohort study (2008–2020) aims to evaluate and compare the outcomes of this technique to the current standard dual rod technique to determine their safety and efficacy.

28 patients in the single rod group (Mean age = 16.4 [SD ±4.0]) and 30 in the double rod group (Mean age = 16.3 [SD±3.5]). Indications included a minimum 2 year follow period, detailed information on the type of implant and a complete pre- and post-operative imaging and medical records. Baseline demographics, comorbidities, and surgical characteristics were collected. Outcomes assessed included the immediate post-op and final follow up angles and general complications. All outcome analysis was performed using a regression approach.

Angles at final follow-up: lumbar (Difference ratio (DR)= 2.60 [95% CI 0.37 – 18.4], p=0.25), thoracic (DR= 1.08 [95% CI 0.19 – 6.28], p=0.92), thoracolumbar (major curve angle) (DR 1.35 [95% CI 0.60 – 3.06], p=0.46) and kyphosis (DR = 0.97 [0.66, 1.42] p=0.86). There was no statistically significant difference, between the two groups, for any of the above angle outcomes as well as for length of surgery, blood loss and complication outcomes.

Both single and double rod instrumentation achieves satisfactory and safe deformity correction which is maintained at final follow up. A larger scale study is warranted to further assess these techniques while also conducting a cost-benefit analysis between them.

Abstract

Aim

With resumption of elective spine surgery services following the first wave of COVID-19 pandemic, we conducted a multi-centre BASS collaborative study to examine the clinical outcomes of surgeries.

Methods

Prospective data was collected from eight spinal centres in the first month of operating following restoration of elective spine surgery following the first wave. Primary outcomes measures were the 30-day mortality rate and postoperative Covid-19 infection rate. Secondary outcomes analysed were the surgical, medical adverse events and length of inpatient stay.

Introduction

Patients with metastatic spinal cord compression (MSCC) or unstable spinal lesions warrant early surgical consultation. In multiple myeloma, chemotherapy and radiotherapy have the potential to decompress the spinal canal effectively in the presence of epidural lesions. Mechanical stability conferred by bracing may potentiate intraosseous and extraosseous bone formation, thus increasing spinal stability. This study aims to review the role of non-operative management in myeloma patients with a high degree of spinal instability, in a specialist tertiary centre.

Methods

Retrospective analysis of a prospectively collected database of 83 patients with unstable myelomatous lesions of the spine, defined by a Spinal Instability Neoplastic Score (SINS) of 13–18. Data collected include patient demographics, systemic treatment, neurological status, radiological presence of cord compression, most unstable vertebral level and presence of intraosseous and extraosseous bone formation. Post-treatment scores were calculated based on follow-up imaging which was carried out at 2 weeks for cord compression and 12 weeks for spinal instability. A paired t-test was used to identify any significant difference between pre- and post-treatment SINS and linear regression was used to assess the association between variables and the change in SINS.

Background Context

SPECT-CT is a hybrid imaging modality, which has become very well established in the diagnosis of inflammatory, vascular and malignant processes affecting the spine. However, little evidence exists on its application with degenerative pathologies.

Purpose & Study Design

Systematic review on the use of SPECT-CT in the diagnosis of degenerative facet joint arthropathy.

Difficulties arise when counselling younger patients on the long-term sequelae of a minor knee chondral defect. This study assesses the natural history of patients with grade 2 Outerbridge chondral injuries of the medial femoral condyle at arthroscopy. We reviewed all arthroscopies performed by one surgeon over 12 years with Outerbridge grade 2 chondral defects. Patients aged 30 to 59 were included. Meniscal injuries found were treated with partial menisectomy. All patients had five-year follow up minimum. Primary outcome measure was further interventions of total or unicondylar arthroplasty or high tibial osteotomy. We analysed 3,344 arthroscopies. Average follow up was 10 years (Range 5–17 years). A total of 357 patients met inclusion criteria of which 86 had isolated medial femoral condyle disease. Average age was 50 at the time of arthroscopy. Average BMI at surgery was 31.7 and average chondral defect area was 450 mm2. Isolated MFC chondral disease had a 10.5% intervention rate. Intervention occurred at a mean of 8.5 years post primary arthroscopy. In young patients Outerbridge II chondral injuries affecting ≥2 compartments have a high rate of further intervention within a decade. This information is crucial in counselling young patients on long-term sequelae of benign chondral lesions.

Introduction

Lisfranc joint injuries account for only 0.2% of all fractures but early diagnosis improves the chances of a better outcom]. Radiographic signs, such as diastasis (>2mm) of the 1–2 interspace, are subtle and. often missed, leading to a poorer outcome. We present a new radiographic sign, less likely to result in missed diagnoses. Null nypothesis: The intermetarsal angle remains unchanged in Lisfranc injuries.

Method

A series of radiographs demonstrating Lisfranc injury were interspersed with normal and postoperative cases. Evidence of fixation was obscured. A selection of Foundation and Core Trainee medical staff measured the intermetatarsal angle (IMA) on two separate occasions. The measuring technique was demonstrated with no explanation for the reason behind the measurement.

The Dawn Hip - An Effective Strategy to Improve the Management of Traumatic Hip Fractures

Introduction

Traumatic hip fractures are managed with nationwide standards, and are regularly audited and published. A previous audit last year at the William Harvey revealed 66% of hip fractures were operated within 48 hours, compared to the national average of 75%. We implemented a strategy to improve this target by introducing the ‘Dawn Hip’ - a hip fracture operation which is prepared for surgery at 8am on the Emergency (CEPOD) list.

Methods

Over a two month period after the introduction of the ‘Dawn hip’, the number of hip operations and start time on the CEPOD list were audited. Performance data were extrapolated from the National Hip Fracture Database (NHFD) and compared nationally.
