The Use of Dorsal Bridge Plate Fixation in the Operative Management of Lisfranc Injuries - A Retrospective Cohort Study at Medium Term Follow-Up.

INTRODUCTION: Traditionally, early surgical management of Lisfranc injuries with transarticular screws (TAS) was deemed to be the optimal treatment. However, concerns of potential iatrogenic articular cartilage disruption has led to discrepancies in opinion amongst surgeons, with many surgeons now utilizing dorsal bridge plates (DBP) for ORIF of Lisfranc injuries. OBJECTIVES: This study sought to investigate the clinical outcomes at medium-term follow-up of consecutive patients in our institution who underwent ORIF with DBP for Lisfranc injuries. METHODS: All consecutive patients who underwent ORIF with DBPs for Lisfranc injuries were identified. Outcomes of interest included; visual analogue scale (VAS), functional foot index (FFI), American Orthopaedic Foot & Ankle Surgeons (AOFAS) hindfoot scores, and complications. RESULTS: Overall, 37 consecutive patients (24 males) with a mean age of 34.8 ± 13.0 years underwent ORIF with DBPs for lisfranc injuries. After a mean 48.3 ± 28.7 months, the mean reported AOFAS and FFI scores were 77.4 ± 23.8 and 31.9 ± 32.7 respectively, with satisfactory reported pain scores as measured by VAS post-operatively at rest and whilst walking (2.2 ± 2.5 and 3.1 ± 2.6 respectively). The reported satisfaction rate was 86.5% (32/37). Overall, 25 patients (67.6%) had subsequent removal of metal or were listed for same, 88% (22/25) of whom did so electively in the absence of broken screws or infection. CONCLUSION: This study found that the use of Dorsal Bridge Plates for Open Reduction and Internal Fixation of Lisfranc Injuries resulted in satisfactory functional outcomes, high rates of patient-reported satisfaction and a low complication rate at medium-term follow-up. LEVEL OF EVIDENCE: Level IV; Retrospective Series of Consecutive Patients.

A Case of Multi-focal Osteonecrosis in the Context of Liver Transplant Following Ingestion of Amanita phalloides Mushroom Toxin.

We present the case of a 44-year-old female who presented with atraumatic avascular necrosis (AVN) of the patella and hips bilaterally, following ingestion of the deadly fungus Amanita phalloides or 'death cap' and subsequent liver transplant. Upon presentation, in the hours following ingestion, our patient required a liver transplant and ICU admission. She was treated by a multidisciplinary team, with input from various specialities. Our patient required steroids in the months following this event. Six months after the liver transplant and subsequent ICU admission, our patient developed hip pain, thus limiting her mobility, ability to engage in physiotherapy and rehabilitation. X-rays were performed that excluded any acute pathology. She was still receiving high-dose steroids at this time. When the pain did not resolve with analgesia, MRI of pelvis and knee was performed and the patient was found to have polyarticular AVN. Acute bilateral total hip replacement was performed and within weeks, the patient returned to physiotherapy and to full rehabilitation. Conservative management of the patella was favoured. Over two years later, the patient can now mobilise independently. The role of acute total hip replacement is evident in this case, and how in performing this surgery, the overall conditioning and health of our patient improved drastically. Currently, cases reporting A. phalloides ingestion are few and we wish to use this case to highlight the differential diagnosis in a patient presenting with joint pain in this context of fungus ingestion, organ transplant or prolonged steroid use.

Infographics Improve Comprehension and Recall at the Orthopaedic Journal Club.

Information graphics, abbreviated to infographics, convey information using visualisations and images. This format of presenting research has been shown to be preferred by 80% of clinicians when compared to text articles. The weekly Journal Club was audited within our institution over a period of 10 weeks. Five weeks of article presentations using plain text abstract displays preceded 5 weeks of infographic display. A multiple-choice questionnaire was constructed weekly so as to test the attendees' recall and comprehension. A total of 1036 multiple-choice questions were answered across the 10 weeks, which included 553 questions (53.4%) based on the standard Journal Club format, and 483 questions (46.6%) on infographic displays. The use of infographics saw significantly improved test results from 42% to 65.8% (p < 0.001). Questions were answered correctly 1.5 times more often following infographic introduction. Infographics were preferred over plain text abstracts by 78% of team members. Infographics enhanced the audience's comprehension and recall of orthopaedic research when used as a presentation tool at the Journal Club. The majority of clinicians preferred infographic displays to plain text abstracts. Research was perceived as being more engaging, and thus more suitable for dissemination, such that key messages could be shared with surgeons, researchers and patients worldwide.

The Utility of a Plain Film Arthrogram to Confirm Acute Liner Dissociation in the Setting of Primary Total Hip Arthroplasty.

Acute Liner dissociation is a well-documented, but uncommon complication of total hip arthroplasty, yet the journey to diagnosis remains undefined. This clinical case report outlines the use of plain film arthrogram for diagnosis in a 53-year-old female who presented to the ED following a fall, describing symptoms of increasing groin pain, reduced range of movement, difficulty weight-bearing and a grinding sensation in her left hip, all on a background of total hip replacement two years ago. Examination revealed impaired flexion, rotation and abduction while AP pelvic X-ray confirmed mild eccentric placement of the femoral head, and lateral X-ray proved joint enlocation. An arthrogram of the left hip was performed the following day with injection of 4mls of iodinated contrast injected into the joint. Inferior dissociation of the liner from the shell was evident. The femoral head and liner were replaced two days later, and the liner was found to have shearing and gross plastic deformation at the rim. The patient reported immediate relief from the groin pain and was discharged on the fourth day postoperatively. This shows how plain film imaging fails in diagnosing acute liner dissociation dynamic fluoroscopic tests, post-arthrography CT and metal artifact reduction sequence magnetic resonance imaging (MARS MRI) have previously been proposed despite their associated wait-time, radiation exposure and financial costs. This case report highlights the role of plain film arthrography as a low risk and low-cost diagnostic tool. The report also suggests the incorporation of radio-dense markers in liners to facilitate the use of arthrography when diagnosing dissociation, also raising awareness of prevention and recognition in what may be an under-reported complication of hip arthroplasty.

Anaesthesia for total hip and knee replacement: A review of patient education materials available online.

Background: Patients frequently consult the internet for health information. Our aim was to perform an Internet-based readability and quality control study using recognised quality scoring systems to assess the patient information available online relating to anaesthesia for total hip and knee replacement surgery. Methods: Online patient information relating to anaesthesia for total hip and knee replacement was identified using Google, Bing and Yahoo with search terms 'hip replacement anaesthetic', 'knee replacement anaesthetic.' Readability was assessed using Flesch Reading Ease (FRE), Flesch-Kincaid grade level (FKGL) and Gunning Fog Index (GFI). Quality was assessed using DISCERN instrument, Health On the Net Foundation seal, and Information Standard mark. Results: 32 websites were analysed. 25% were HONcode certified, 15.6% had the Information Standard. Mean FRE was 55.2±12.8. Mean FKGL was 8.6±1.9. Six websites (18.8%) had the recommended 6 th-grade readability level. Mean of 10.4±2.6 years of formal education was required to read the websites. Websites with Information Standard were easier to read: FKGL (6.2 vs. 9, P < 0.001), GFI (8.8 vs. 10.7, P = 0.04), FRE score (64.2 vs. 9, P = 0.02). Mean DISCERN score was low: 40.3 ± 13. Conclusions: Overall, most websites were poor quality with reading levels too high for the target audience. Information Standard NHS quality mark was associated with improved readability, however along with HONcode were not found to have a statistically significant correlation with quality.  Based on this study, we would encourage healthcare professionals to be judicious in the websites they recommend to patients, and to consider both the readability and quality of the information provided.

Management of Metastatic Spinal Cord Compression in Ireland: Are Surgeons Overlooked?

BACKGROUND: The National Institute of Health and Clinical Excellence (NICE) provide a framework of evidence-based guidelines for the management of metastatic spinal cord compression (MSCC). We aimed to compare our center's provision of service to these best practice guidelines and discuss key shortcomings with their implications for the spinal surgeon. METHODS: Patients with radiologic evidence of MSCC over a 30-month period were identified using the hospital electronic radiological database. A chart review was performed analyzing MSCC management. RESULTS: Forty-one patients were identified. Pain was the most common presenting complaint, occurring in 76% of patients. Radiotherapy alone was the most common therapy employed (93% of patients). A surgical opinion was sought for 51% of patients. Histological diagnosis of the causative lesion occurred in 5 patients from surgical specimens. CONCLUSIONS: Incongruities between NICE guidelines and our practice exist. Early involvement of the spinal surgical services needs to be encouraged. Establishing a histological diagnosis of the spinal lesion should be seen as of therapeutic importance.

Radiographic and Functional Outcomes following Knee Arthrodesis Using the Wichita Fusion Nail.

The purpose of this study was to report both the radiographic and functional outcomes of patients undergoing knee arthrodesis with the Wichita Fusion Nail (WFN) within the Republic of Ireland and compare the results to existing literature. Patient charts and radiographs were reviewed on all patients who had a WFN implanted in Ireland to date. Patients were invited to complete a Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score as a functional assessment. Twenty-three patients were identified. Patients had an average of 8 (range: 0-26) knee surgeries prior to arthrodesis. The most common indication was failed arthroplasty due to recalcitrant infection (69.5%). Successful fusion occurred in 60.8% of patients. The mean time to fusion was 9.21 months. The mean WOMAC score was 58.55 with a range of 31 to 96. We found a rate of arthrodesis lower than that reported in other published series. However, the rate of major complications was comparable to those published previously, reflecting the often-challenging patient cohort. Our study shows that the WFN should not be viewed as a near-universally successful option to salvage an unreconstructable knee.
