Six-year review of traumatic brain injury in a regional trauma unit: demographics, contributing factors and service provision in Ireland.

BACKGROUND: Traumatic brain injury (TBI) represents a significant burden of care for acute surgical services, particularly in the absence of on-site neurosurgical cover or sufficient post-acute rehabilitation facilities. We examine factors contributing to TBI, prolonged lengths of stay (LoS) and implications for hospital resources. Long-term outcomes are assessed. METHODS: This is a retrospective cohort study of patients admitted to a regional trauma unit with TBI from 2008 to 2013. Patients with LoS > 48 h were assessed. Demographic, clinical and longitudinal mortality data were collected using electronic clinical and radiological systems and chart review. RESULTS: A total of 690 patients presented with TBI from 2008 to 2013; 213 patients with LoS > 48 h were assessed. One hundred and thirty (61%) were male. Mean age was 56 years (±SD 24). Mechanical fall was the most frequent injury mechanism (n = 120/213, 56%). Twenty-five per cent were associated with alcohol consumption; these were more likely to be male, involved in an Road Traffic Accident (RTA) or assault and necessitate transfer to a neurosurgical unit (p < 0.001, p = 0.029, p < 0.001, p = 0.05). A total of 112 patients(53%) had a prolonged LoS (>2 weeks). Mean LoS was 20 days (±SD 35), increasing to 39 days for patients requiring neurosurgical intervention. The 12-month all-cause mortality rate was 12%. CONCLUSIONS: TBIs result in significant utilisation of acute inpatient bed days. Improved rehabilitation services and strategies to reduce acute hospital LoS are warranted.

Ultrasound-guided aspiration of wrist ganglions: a follow-up survey of patient satisfaction and outcomes.

BACKGROUND: Ganglion cysts are one of the most frequently occurring masses of the wrist, often causing pain and interfering with daily activity. Ultrasound (US)-guided aspiration is a treatment for ganglion cysts of the wrist. PURPOSE: To examine the results and patient satisfaction of US-guided aspiration of wrist ganglion cysts. MATERIAL AND METHODS: Medical records from August 2009 through December 2013 were reviewed to identify all adult patients referred to a single musculoskeletal radiologist for US-guided aspiration of a painful wrist ganglion cyst. Records were reviewed for patient demographics, cyst size, location, and morphology. Outcomes and patient satisfaction were evaluated using a telephone questionnaire at a minimum of 9 months after the procedure. RESULTS: Of 56 consecutive patients identified, follow-up data were available for 39 patients (69%) at a minimum of 9 months. There were 21 volar and 18 dorsal ganglion cysts. The overall recurrence rate was 20% (8 of 39 patients) and only five patients reported a pain score of greater than 2 out of 10. The mean age of patients with recurrence of the cyst was greater than that of patients without recurrence (52 vs. 35 years, P = 0.03). Satisfaction with the outcome was high and varied by recurrence. There were no acute complications including infection, hemorrhage, or allergic reaction. CONCLUSION: US-guided aspiration is a safe and potentially effective treatment for ganglion cysts of the wrist, with high patient satisfaction. US-guided aspiration may be particularly advantageous for volar ganglion cysts, and in patients who are poor surgical candidates.

Functional outcomes of replantation following radiocarpal amputation.

PURPOSE: To assess the long-term functional and clinical outcomes of patients who have undergone replantation after radiocarpal amputation. METHODS: We performed a retrospective review of radiocarpal joint amputations at a level 1 trauma center over a 13-year period. Medical records of patients treated with replantation were queried for injury data, operative reports, complications, and clinical progress. Patients who met inclusion criteria were contacted for long-term follow-up. We measured total active motion of each digit, strength (grip and pinch), and 2-point discrimination. Functional outcomes were assessed with Disabilities of Arm, Shoulder, and Hand score, Mayo Wrist Score, Patient-Rated Wrist Evaluation, and Michigan Hand Questionnaire. Descriptive statistics were calculated, including frequencies for categorical variables and means and ranges for continuous variables. RESULTS: Six patients met the inclusion criteria. The mean age was 36 years (range, 26-50 y). Five patients were available at a mean follow-up of 3.9 years (range, 1.0-6.9 y). Compared with the contralateral uninjured extremity, total active motion of the hand was 38% (range, 26% to 59%) and grip strength was 9% (range, 0% to 18%). Neither tip nor key pinch was present. Mean 2-point discrimination was 10.6 mm (range, 8-12 mm). All mean outcome scores indicated moderate disability, including Disabilities of Arm, Shoulder, and Hand (76; range, 45-82), Mayo Wrist Score (23; range, 5-50), Patient-Rated Wrist Evaluation (86; range, 56-98), and Michigan Hand Questionnaire (27; range, 15-55). Two patients were able to return to work and 3 were permanently disabled. All patients were satisfied with the hand function. CONCLUSIONS: Successful replantation for a radiocarpal joint amputation is associated with major restriction of motion, decreased strength, and moderate disability on functional outcome assessments. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Telemedicine in orthopaedic surgery during the COVID-19 pandemic : patient attitudes and barriers.

AIMS: This study assesses patient barriers to successful telemedicine care in orthopaedic practices in a large academic practice in the COVID-19 era. METHODS: In all, 381 patients scheduled for telemedicine visits with three orthopaedic surgeons in a large academic practice from 1 April 2020 to 12 June 2020 were asked to participate in a telephone survey using a standardized Institutional Review Board-approved script. An unsuccessful telemedicine visit was defined as patient-reported difficulty of use or reported dissatisfaction with teleconferencing. Patient barriers were defined as explicitly reported barriers of unsatisfactory visit using a process-based satisfaction metric. Statistical analyses were conducted using analysis of variances (ANOVAs), ranked ANOVAs, post-hoc pairwise testing, and chi-squared independent analysis with 95% confidence interval. RESULTS: The survey response rate was 39.9% (n = 152). The mean age of patients was 51.1 years (17 to 85), and 55 patients (38%) were male. Of 146 respondents with completion of survey, 27 (18.5%) reported a barrier to completing their telemedicine visit. The majority of patients were satisfied with using telemedicine for their orthopaedic appointment (88.8%), and found the experience to be easy (86.6%). Patient-reported barriers included lack of proper equipment/internet connection (n = 13; 8.6%), scheduling difficulty (n = 2; 1.3%), difficulty following directions (n = 10; 6.6%), and patient-reported discomfort (n = 2; 1.3%). Barriers based on patient characteristics were age > 61 years, non-English primary language, inexperience with video conferencing, and unwillingness to try telemedicine prior to COVID-19. CONCLUSION: The barriers identified in this study could be used to screen patients who would potentially have an unsuccessful telemedicine visit, allowing practices to provide assistance to patients to reduce the risk of an unsuccessful visit.

FOXE1 polymorphism rs965513 predisposes to thyroid cancer in a European cohort.

Objective: FOXE1 is an intronless gene on chromosome 9 which plays a significant role in thyroid morphogenesis. Mutations in FOXE1 are associated with thyroid phenotypes including congenital hypothyroidism, thyroid dysgenesis and thyroid cancer. This study aims to investigate the frequency and impact of a SNP (rs965513, G>A) at 9q22.23 in a Western European cohort of patients with differentiated thyroid cancer(DTC), compared to controls. Design: This is a candidate gene case control study. Methods: 277 patients with histologically confirmed DTC were recruited from tertiary referral centres in Ireland and France. 309 cancer-free controls were recruited from the community. DNA was extracted from buccal swabs or whole blood of control subjects and patients with DTC. Allelic and genotypic frequencies among patients were compared with controls, to assess the risk for disease conferred by homozygous and heterozygous carriers compared to WT genotypes. Genotyping was performed using Taqman-based PCR. Results: 277 patients with confirmed DTC and 309 non-cancer controls were genotyped for the variant (rs965513). The frequency of the minor allele among cases was 0.45 compared to 0.34 among controls. The genotypic odds ratio for heterozygotes was 1.66 (CI 1.16-2.39, P =0.00555), increasing to 2.93 (CI 1.70-5.05, P =0.00007) for rare homozygotes. All subjects were in Hardy-Weinberg equilibrium (±χ2, P =0.09, P =0.07 respectively). Conclusions: This FOXE1 polymorphism is a low penetrance variant associated with DTC susceptibility in this cohort. The minor allele was identified among patients with thyroid cancer significantly more frequently than controls. An allele dosage effect was observed, with rare homozygous genotypes conferring greater risk than heterozygotes.

Differentiated Thyroid Cancer: How Do Current Practice Guidelines Affect Management?

BACKGROUND: International best-practice guidelines recommend completion thyroidectomy and radioiodine remnant ablation (RRA) for patients with differentiated thyroid cancer (DTC) > 4 cm or with specific risk factors. Patients with DTC < 1 cm without risk factors are recommended for lobectomy alone. Indications for aggressive surgery and RRA are less clearly defined for tumours measuring 1-4 cm. A personalised approach to decision-making is recommended. OBJECTIVES: This study assesses therapeutic approaches to DTC as compared to the current British Thyroid Association (BTA) clinical practice guidelines. We ascertained the effect of equivocal guidance in the 1-4 cm tumour cohort on contemporary practice patterns. METHODS: Data were obtained from a prospectively maintained thyroid cancer database of patients treated for DTC in a tertiary referral centre at the University Hospital Galway. Consecutive patients attending a dedicated thyroid cancer clinic between August 2014 and August 2017 were included. Clinicopathological characteristics and management strategies were assessed. RESULTS: Ninety-four percent (n = 168/178) of patients were surgically managed in adherence with guidelines. A minority (n = 10) received surgery not aligned with guidelines. Ninety-seven percent (n = 172/178) of RRA treatment decisions were in accordance with guidelines. The BTA guidelines recommended a personalised decision-making approach for 18.0% (n = 32) and 44.9% (n = 80) of surgery and RRA treatment decisions, respectively. The more aggressive, treatment-driven approach was typically favoured by the multidisciplinary team, with 97% (n = 31/32) undergoing completion thyroidectomy and 100% (n = 80) proceeding to RRA. CONCLUSIONS: Management of DTC at our institution closely adheres to contemporary clinical practice guidelines. The finding of more aggressive management in those requiring a personalised decision-making approach highlights the requirement for improved risk stratification in this cohort to ratio-nalise management strategies.

National trends in ambulatory surgery for upper extremity fractures: a 10-year analysis of the US National Survey of Ambulatory Surgery.

BACKGROUND: Upper extremity fractures are increasing in frequency and have profound socioeconomic implications. The purpose of this study was to assess trends in ambulatory upper extremity fracture fixation in the USA from 1996 to 2006 using data from the National Survey of Ambulatory Surgery (NSAS). METHODS: The NSAS was used to identify cases of closed forearm, carpal, metacarpal, and phalanx fractures treated with open or closed reduction with internal fixation in 1996 and 2006. Data were analyzed for trends in fracture location, age, gender, facility type, payor status, and anesthesia type. US census data were used to obtain national population estimates. RESULTS: Over the 10-year study period, there was a 54.4 % increase in the population-adjusted rate of upper extremity fractures treated with internal fixation (34.6 to 53.4 per 100,000 capita). There was a 173 % increase in the age-adjusted rate of patients over 55 years treated with internal fixation. There was a 505 % increase in the number of cases performed at freestanding surgical centers compared to hospital-based facilities. Though the majority of cases involved general anesthesia, regional anesthesia (16.6 versus 20.6 %) and monitored anesthesia care (7.1 versus 11.8 %) increased in frequency. Private insurance groups funded the majority of surgeries in both study years. CONCLUSION: The volume of ambulatory surgery for upper extremity fractures has increased dramatically from 1996 to 2006. Operative treatment of upper extremity fractures has increased markedly. Our analysis provides valuable information for providers and policy-makers for allocating the appropriate resources to help sustain this volume.

Resident selection of Hand Surgery Fellowships: a survey of the 2011, 2012, and 2013 Hand Fellowship graduates.

BACKGROUND: We desired information from the recent, current, and future matched hand surgery fellows regarding their residency training, number of interviews, position matched, cost of interviewing, influences, opinions on future hand training models, and post-fellowship job information. METHODS: Institutional review board approval was obtained from our institution to submit an online survey. An email was sent to the coordinators of all US Hand Fellowships to be forwarded to their fellows with graduation years 2011, 2012, and 2013, as well as directly to the fellows if their email addresses were provided. Data on the application process, relative importance of program attributes, and opinions regarding optimal training of a hand surgeon were collected. Statistical analysis was performed with respect to the training background and graduation year of the respondent. RESULTS: The survey was completed by 137 hand surgery fellows. Seventy-one percent of the survey responders were from an orthopedic residency background, 20 % from plastic, and 7 % from general surgery. Forty-four percent of all of the respondents matched into their first choice. The type of operative cases performed by the current fellows was most often selected as very important when making their rank list. Seventy-seven percent of the respondents reflected their personal preference in fellowship model to be a 1-year fellowship program. CONCLUSIONS: The field of hand surgery is unique in that it has residents from multiple training backgrounds who all apply to one fellowship. The current fellowship model allows for diversity of training and the possibility of obtaining a second fellowship if desired.

Ulnar nerve component to innervation of thumb carpometacarpal joint.

PURPOSE: Thumb carpometacarpal (CMC) joint arthritis is one of the most common problems addressed by hand surgeons. The gold standard of treatment for thumb CMC joint arthritis is trapeziectomy, ligament reconstruction and tendon interposition. Denervation of the thumb CMC joint is not currently used to treat arthritis in this joint due to the failure of the procedure to yield significant symptomatic relief. The failure of denervation is puzzling, given that past anatomic studies show the radial nerve is the major innervation of the thumb CMC joint with the lateral antebrachial nerve and the median nerve also innervating this joint. Although no anatomic study has ever shown that the ulnar nerve innervates the CMC joint, due to both the failure of denervation and the success of arthroscopic thermal ablation, we suspect that previous anatomic studies may have overlooked innervation of the thumb CMC joint via the ulnar nerve. METHODS: We dissected 19 formalin-preserved cadaveric hand-to-mid-forearm specimens. The radial, median and ulnar nerves were identified in the proximal forearm and then followed distally. Any branch heading toward the radial side of the hand were followed to see if they innervated the thumb CMC joint. RESULTS: Eleven specimens (58%) had superficial radial nerve innervation to the thumb CMC joint. Nine specimens (47%) had median nerve innervation from the motor branch. Nine specimens (47%) had ulnar nerve innervation from the motor branch. CONCLUSIONS: We believe this is the first study to demonstrate that the ulnar nerve innervates the thumb CMC joint This finding may explain the poor results seen in earlier attempts at denervation of the thumb CMC, but the more favorable results with techniques such as arthroscopy with thermal ablation.
