Isometric thumb extension exercise as part of a multimodal intervention for de Quervain's syndrome: A randomised feasibility trial

Introduction: de Quervain's syndrome is a painful condition commonly presented to hand therapists. Exercise is utilised as an intervention, but isometric exercise has not been investigated. We aimed to assess the feasibility and safety of isometric thumb extension exercise for de Quervain's syndrome and to explore differences between high-load and low-load isometric exercise. Method(s): This parallel-group randomised clinical feasibility trial included individuals with de Quervain's syndrome. All participants underwent a 2 week washout period where they received an orthosis, education, and range of motion exercises. Eligible participants were then randomised to receive high or low-load isometric thumb extension exercises, performed daily for 4 weeks. Feasibility and safety were assessed by recruitment and drop-out rates, adherence, adverse events, and participant feedback via semi-structured interviews. Secondary outcomes included patient-reported outcomes for pain and function, and blinded assessment of range of motion and strength. Result(s): Twenty-eight participants were randomised. There were no drop-outs after randomisation, and no serious adverse events. Adherence to exercise was 86.7%, with 84% of participants stating they would choose to participate again. There were clinically and statistically significant improvements in pain and function over time (p < 0.001) but not in range of motion or strength. There were no statistically significant between-group differences. Conclusion(s): Isometric thumb extension exercise within a multimodal approach appears a safe and feasible intervention for people with de Quervain's syndrome. A large multi-centre trial would be required to compare high- and low-load isometric exercises. Further research investigating exercise and multimodal interventions in this population is warranted.Copyright © The Author(s) 2023.

Rates of Lapidus Procedures in the US Military Before and After the Advent of and Advocacy for Tri-Plane Lapidus Corrective Surgery.

Tri-plane corrective Lapidus surgery has been described as advantageous with respect to its anatomic basis and outcomes. Because the procedure has been broadly publicized, changes in overall Lapidus procedure rates due to increased numbers of patients opting for the tri-plane approach could have occurred. Data supporting this possibility appears lacking. We employed official personnel and health records of the total active-duty US military to conduct a retrospective cohort study of Lapidus surgery rates before and after the advent of the tri-plane corrective Lapidus procedure. Least-squares and locally-weighted scatterplot smoother regression functions were used to confirm time trends. Sociodemographic and occupational traits of Lapidus patients were compared using 2-sided t tests and chi square tests. Lapidus surgery rates among hallux valgus patients decreased during 2014 to 2016 and increased during 2017 to 2021. While multiple factors might explain these trends, they coincide with the advent of and advocacy for tri-plane Lapidus surgery. The results support the possibility that its rise influenced overall Lapidus rates in this population. As these findings represent limited evidence of such an influence, further research is required to confirm a causal link. If such a link is found, and if the ongoing research suggests that superior outcomes are associated with tri-plane Lapidus surgery, substantial implications could exist for this population. Benefits might include enhanced medical readiness due to the importance of lower extremity function during military duties. Additional research is needed to confirm the impact of the procedure and to determine whether Lapidus surgery rate patterns in civilian populations mirror these findings.

Evaluation of factors associated with surgical site infection in equine proximal interphalangeal joint arthrodesis: 54 cases (2010-2019).

BACKGROUND: The frequency of surgical site infection (SSI) following orthopaedic implant placement in horses has been reported but not compared with respect to specific antibiotic protocols administered. OBJECTIVES: To determine factors associated with SSI in horses undergoing proximal interphalangeal joint (PIPJ) arthrodesis including perioperative antibiotic protocols. METHODS: Records were evaluated (2010-2019), and horses undergoing PIPJ arthrodesis were identified. Patient signalment, supervising surgeon, reason for surgery, limb, implants placed, anaesthetic time, duration casting/coaptation postoperatively, antibiotic regimen and incidence/onset SSI were recorded. Bayesian and frequentist logistic regressions were used to estimate the contribution of covariates to infection occurrence. RESULTS: Fifty-four PIPJ arthrodeses were performed. SSI occurred in 2/54 (3.7%) on day 15,30. Arthrodesis was performed most commonly for osteoarthritis (33/54, 61.1%), fracture (11/54, 20.4%), and subluxation (5/54, 9.3%). Perioperative systemic antibiotics were administered 1-3 days (15/54, 27.8%) or > 3 days (39/54, 72.2%). Antibiotic protocols included cefazolin/gentamicin (20/54, 37%), cefazolin/gentamicin/doxycycline (14/54, 25.9%) and potassium penicillin/gentamicin (10/54, 18.5%). Regional limb perfusion was performed preoperatively 31/54 (57.4%) and postoperatively 7/54 (13%). Survival to dismissal was 98.1% (53/54 horses) with one horse euthanized due to support limb laminitis. No association was identified between antibiotic selection or duration (1-3 vs. > 3 days), pre-operative regional antibiotic perfusion, intraoperative antibiotic lavage or anaesthetic time (< or > 3 h) and SSI; however, modelling was complicated by quasi-complete or complete separation of the data. Bayesian analysis (but not frequentist analysis) indicated an association between post-operative regional antibiotic perfusion and SSI. Limitations include the retrospective nature of data collection and the low rate of infection overall. CONCLUSIONS: The prevalence of SSI in this population was lower than that in previous reports of equine orthopaedic internal fixation. There was no difference in SSI rate in cases administered systemic antibiotics for 1-3 days or >3 days, or for those horses that did or did not receive preoperative regional antibiotic perfusion.

Clinical and Radiologic Results of a Human Bone Graft Screw in Tarsometatarsal II/+III Arthrodesis.

BACKGROUND: For arthrodesis of the tarsometatarsal joints, there is the possibility of using a transplant screw made of allogenic human bone material (Shark Screw). This article investigates the clinical outcome and radiologic integration of the allogenic bone screw for arthrodesis of the tarsometatarsal joints II/+III. METHODS: This is a prospective study involving 20 feet of 17 patients who received TMT II/+III arthrodesis with an allogenic bone screw. A visual analog scale (VAS pain and function), Foot Function Index (FFI), American Orthopaedic Foot & Ankle Society (AOFAS) midfoot score, and Foot and Ankle Outcome Score (FAOS) were used as measures to compare preoperative with postoperative results. Radiologic integration in the recipient bone was also evaluated. RESULTS: A significant mean pre- to postoperative improvement of all evaluated scores has been observed (P < .05) after a mean follow-up of 15.87 months (minimum 12 months, maximum 33 months). VAS score (pain) decreased from 7.6 to 1.4 points as well as a decrease of the VAS (function) from 7.25 to 1.8 points. Further, a reduction of the FFI from 62.3% to 16.7% and an increase from 29.7 to 79.9 points of the AOFAS was detected. Analyzing the FAOS score, in all surveyed subscales, there was an increase in the score (Symptoms: 55.2 to 85.6 points; Pain: 30.5 to 86.9 points; Function: 33.1 to 88.3 points; Quality of life: 27.8 to 79.7 points). Moreover, in all cases, a complete radiologic integration into the receiving bone was appreciated, and after a minimum follow-up time from 12 months, the screw in 19 feet (95%) was no longer distinguishable from the original bone. CONCLUSION: With these first results of the allogenic bone screw in TMT II/+III arthrodesis, a significant improvement from preoperative to postoperative was confirmed in the collected scores, and a full radiographic integration was demonstrated in all feet.

Impact Of COVID-19 Pandemic and Updated Utilization Patterns of Sacroiliac Joint Injections from 2000 to 2020 in The Fee-For-Service (FFS) Medicare Population.

BACKGROUND: Among the multiple causes of low back and lower extremity pain, sacroiliac joint pain has shown to be prevalent in 10% to 25% of patients with persistent axial low back pain without disc herniation, discogenic pain, or radiculitis. Over the years, multiple Current Procedural Terminology (CPT) codes have evolved with the inclusion of intraarticular injections, nerve blocks, and radiofrequency neurotomy, in addition to percutaneous sacroiliac joint fusions. Previous assessments of utilization patterns of sacroiliac joint interventions only included sacroiliac joint intraarticular injections, since the data was not available prior to the introduction of new codes. A recent assessment revealed an increase of 11.3%, and an annual increase of 1.2% per 100,000 Medicare population from 2009 to 2018, showing a decline in growth patterns. During the past 2 years, the COVID-19 pandemic has also had significant effects on the utilization patterns of sacroiliac joint interventions. STUDY DESIGN: The impact of the COVID-19 pandemic and analysis of growth patterns of sacroiliac joint interventions (intraarticular injections, nerve blocks, radiofrequency neurotomy, arthrodesis and fusion) was evaluated from 2010 to 2019 and 2010 to 2020, with a comparative analysis from 2019 to 2020 to assess the impact of the COVID-19 pandemic. OBJECTIVES: To update utilization patterns of sacroiliac joint interventions with assessment of the impact of the COVID-19 pandemic. METHODS: The Centers for Medicare and Medicaid Services (CMS) Physician/Supplier Procedure Summary (PSPS) Master dataset was utilized in the present analysis. RESULTS: The results of this evaluation demonstrated a significant impact of the COVID-19 pandemic with a 19.2% decrease of utilization of sacroiliac joint intraarticular injections from 2019 to 2020. There was a 23.3% increase in sacroiliac joint arthrodesis and a 5.3% decrease for sacroiliac joint fusions with small numbers from 2019 to 2020. However, data was not available for sacroiliac joint nerve blocks and sacroiliac joint radiofrequency neurotomy as these codes were incorporated in 2020. Overall, from 2010 to 2019, sacroiliac joint intraarticular injections showed an annual increase of 0.9% per 100,000 Medicare population. Sacroiliac joint arthrodesis and fusion showed an annual increase from 2010 to 2020 per 100,000 Medicare population of 29% for arthrodesis and 13.3% for fusion. LIMITATIONS: Limitations of this study include a lack of inclusion of Medicare Advantage patients constituting approximately 30% to 40% of the overall Medicare population. As with all claims-based data analyses, this study is retrospective and thus potentially limited by bias. Finally, patients who are non-Medicare are not part of the dataset. CONCLUSIONS: The study shows the impact of the COVID-19 pandemic with a significant decrease of intraarticular injections of 19.2% from 2019 to 2020 per 100,000 Medicare population. These decreases of intraarticular injections are accompanied by a 5.3% decrease of fusion, but a 23.3% increase of arthrodesis from 2019 to 2020 per 100,000 Medicare population. Overall, the results showed an annual increase of 0.9% per 100,000 Medicare population for intraarticular injections, a 35.4% annual increase for sacroiliac joint arthrodesis and an increase of 15.5% for sacroiliac joint fusion from 2010 to 2019.

Expanding Indications of Primary Arthrodesis in Selected Individuals for Managing Complex Hindfoot Trauma During COVID-19 Pandemic.

Background: During the COVID-19 pandemic, public health measures to encourage social distancing have been implemented, including cancellation of outdoor activities, organized sports, and schools/colleges. Neglected hindfoot fractures have emerged as a consequence with increased frequency. Similarly, complex ankle and pilon fractures that require staged management, prolonged hospital stay, and soft-tissue care have emerged as a potential concern as prolonged exposure to healthcare setting adds to risk of acquiring as well as transmitting COVID-19 infection. The authors present their experience with expanding these indications for hindfoot arthrodesis as they encounter a greater number of neglected ankle and hindfoot trauma. Methods: This was a retrospective observational study of collected data from the trauma unit of our hospital. Inclusion criteria included all trauma classified by the AO/OTA as occurring at locations 43, and who underwent subtalar and ankle arthrodesis. This included distal tibia, malleolar, talus, and calcaneus fractures. These patients were followed up to at least 6 months till complete fracture union. Results: A total of 18 patients underwent arthrodesis of either the ankle or subtalar joint between March and October 2020. Mean age of patients undergoing arthrodesis of the hindfoot was 69.2 years (43-84 years). Indications for the procedure included Displaced and comminuted intra-articular distal tibia fractures in elderly (6 patients), Malunited ankle fractures (2 patients), Neglected Ankle fractures managed conservatively (3 patients), Calcaneus fractures (5 patients), and neglected Talus body fracture (2 patients). All patients were followed up to at least 6 months and everyone went onto successful painless union between 3 and 6 months of the arthrodesis procedure without any significant complications. Conclusion: In summary, COVID-19 pandemic has led to a change in paradigm of trauma management and foot and ankle management is no different than other musculoskeletal trauma systems. The authors propose an expansion of indications for hindfoot arthrodesis in managing complex hindfoot trauma in pandemic situation.
