ABSTRACT

INTRODUCTION: First metatarsophalangeal joint (MTPJ) arthrodesis is a common treatment for various foot conditions, with nonunion as a frequent complication. The incidence of nonunion varies widely in the literature. In particular, males have a higher risk of nonunion than females. This is possibly due to biomechanical and anatomical differences, as men have on average larger feet than women. This study therefore aims to explore whether shoe size, as a proxy for foot size, affects nonunion rates and could explain the gender disparity in nonunion rates. METHODOLOGY: An exploratory analysis of retrospectively collected data from patients who underwent primary first MTPJ arthrodesis in a single secondary hospital between January 2012 and December 2019. Additional data on body weight, height, and shoe size were prospectively collected from patients. RESULTS: Among 261 included patients, 57 (21.8%) experienced nonunion. Nonunion incidence was higher in males (18, 26.9%) than in females (39, 20.1%). Self-reported shoe size showed no significant association with nonunion in both univariate and multivariate analyses. DISCUSSION: The study's findings suggest that shoe size, as a proxy for foot size, is not associated with nonunion after the first MTPJ arthrodesis. Despite observing a gender difference in nonunion rates, this disparity could not be explained by shoe size. CONCLUSIONS: Shoe size as a proxy for foot size appears to have no clinical association with nonunion following the first MTPJ arthrodesis.

ABSTRACT

BACKGROUND: Arthrodesis of the first metatarsophalangeal joint is the current treatment of choice for symptomatic advanced hallux rigidus and moderate-to-severe hallux valgus. There are different methods to perform arthrodesis, yet no consensus on the best approach. Therefore, this study aimed to determine the effects of preoperative and postoperative hallux valgus angle (HVA), joint preparation and fixation technique, and postoperative immobilization on the incidence of nonunion. METHODS: A retrospective multicenter cohort study was performed that included 794 patients. Univariate and multiple logistic regression was conducted to determine associations between joint preparation, fixation techniques, postoperative immobilization, weightbearing, and pre- and postoperative HVA with nonunion. RESULTS: Nonunion incidence was 15.2%, with 11.1% symptomatic and revised. Joint preparation using hand instruments (OR 3.75, CI 1.90-7.42) and convex/concave reamers (OR 2.80, CI 1.52-5.16) were associated with greater odds of a nonunion compared to planar cuts. Joint fixation with crossed screws was associated with greater odds of nonunion (OR 2.00, CI 1.11-3.42), as was greater preoperative HVA (OR 1.02, CI 1.00-1.03). However, the latter effect disappeared after inclusion of postoperative HVA in the model, with a small association identified between residual postoperative HVA and nonunion (OR 1.04, CI 1.01-1.08). Similarly, we found an association between odds of nonunion and higher body weight (OR 1.02, CI 1.01-1.04) but not of body mass index. CONCLUSION: Based on our results, first metatarsophalangeal joint arthrodesis with planar cuts and fixation with a plate and interfragmentary screw is associated with the lowest odds of resulting in a nonunion. Higher body weight and greater preoperative HVA were associated with slight increase in rates of nonunion. It is crucial to properly correct the hallux valgus deformity during surgery. LEVEL OF EVIDENCE: Level III, retrospective case control study.

ABSTRACT

Purpose: A systematic review to determine the effect of different types of joint preparation, joint fixation, and postoperative weight-bearing protocols on non-union frequency in first metatarsophalangeal joint (MTPJ) arthrodesis in patients with moderate-to-severe hallux valgus. Material and methods: A systematic literature search (PubMed and EMBASE), adhering to PRISMA guidelines. Data on MTPJ preparation, fixation, weight-bearing, and non-union in patients with moderate-to-severe hallux valgus were collected. Quality assessment was performed using the Coleman Methodology Score. Results: Sixteen studies (934 feet) were included, generally of medium quality. Overall non-union rate was 7.7%. At 6.3%, convex/concave joint preparation had the lowest non-union rate vs 12.2% for hand instruments and 22.2% for planar cuts. Non-union of 2.8% was found for joint fixation with a plate combined with a lag screw vs 6.5% for plate fixation, 11.1% for crossed screw fixation, and 12.5% for a plate with a cross plate compression screw. A 5.1% non-union frequency was found following postoperative full weight-bearing on a flat shoe vs 9.3% for full weight-bearing on a heel weight-bearing shoe and 0% for a partial weight-bearing regimen. Conclusion: Based on medium-quality papers, joint preparation with convex/concave reamers and joint fixation with a plate using a lag screw show the lowest non-union rate. Full postoperative weight-bearing in a stiff-soled postoperative shoe is safe and not associated with non-union vs a more protective load-bearing regimen. Further research should focus on larger sample sizes, longer follow-ups, and stronger study designs.

ABSTRACT

The incidence of nonunion after first metatarsophalangeal joint (MTP-1) arthrodesis was found to be high in our clinic. By raising awareness for the problem, making a uniform surgical treatment protocol, banning the commonly used convex-concave reamers, and promoting solely the use of hand instruments to prepare the joint for arthrodesis, we tried to decrease the numbers of nonunion. This prospective cohort study included all patients who underwent MTP-1 fusion between January 2018 and March 2019. Patients were treated according to a standardized protocol, using hand instruments to prepare the joint for fusion. Anthropometric and therapy-related data were collected and compared with an earlier 2015-2016 cohort that was retrospectively assessed. Furthermore, the frequency of nonunion between convex-concave reamers and hand instruments was compared. A total of 53 patients underwent MTP-1 fusion surgery. The incidence of nonunion was 3.8%, significantly lower than the 24.1% in 2015 to 2016 (p = .002). Multivariate regression analysis showed a 7.11 times higher risk of nonunion in 2015 to 2016 compared with 2018 to 2019 (95% confidence interval [CI] 1.55 to 32.55) (p = .012). Furthermore, an increase of 10° in HVA showed a 1.52 risk of occurrence of nonunion (95% CI 1.07 to 2.17) (p = .021). The use of convex/concave reamers was univariately associated with a 3.61 times higher risk of nonunion (95% CI 1.14 to 11.43) (p = .029); however, after correction for preoperative HVA, the preparation method was no longer associated with the occurrence of nonunion (p = .108). Patients suffering from severe hallux valgus had nonunion in 32.1% of cases. Incidence of nonunion after MTP-1 arthrodesis was significantly reduced by raising awareness and by standardizing the treatment protocol. There was no significant difference in nonunion frequency between the methods of joint surface preparation. Severe hallux valgus is prone to nonunion, and more research into this indication for MTP-1 fusion and outcome is needed.

ABSTRACT

BACKGROUND: Treatment and rehabilitation protocol for hip arthroplasty differs between Germany and the Netherlands. The Dutch system promotes fast-track surgery whereas in Germany conventional care is provided with a longer hospital stay including rehabilitation. Clinical outcome, patient satisfaction and costs in both treatment protocols were compared in a prospective setup. MATERIAL AND METHODS: This prospective cohort study included patients allocated for primary THA in 3 German and 1 Dutch hospital in the border region. Patient-reported outcome scores (PROMS) were measured pre- and postoperatively at 6 and 12 months including the Oxford Hip Score, SF12 survey, visual analogue scale for satisfaction and pain. Length of hospitalisation and availability of postoperative rehabilitation were recorded. In addition, a total cost estimation was calculated using health insurers data. RESULTS: A total of 360 consecutive patients were included; 175 THA in Germany compared to 185 THA in the Netherlands. No cross-border healthcare was encountered in both cohorts. Mean length of hospitalisation was 11.3 (range 6-23) days in Germany, compared to 4.4 (range 3-25) days in the Netherlands. In Germany 92% of the patients was discharged with inpatient (72%) or outpatient (20%) rehabilitation, compared to 21% with only inpatient rehabilitation in the Netherlands. No significant differences were measured regarding the PROMS and patient satisfaction between both countries. Due to profound differences in health care financing only a global cost estimation could be made and no major differences were encountered. CONCLUSION: Germany and the Netherlands both offer highly protocolled care for THA with comparable functional outcome and patient satisfaction with treatment after 12 months. Despite the length of hospitalisation in Germany is significantly longer including a more intensive rehabilitation programme, no significant differences were recorded regarding functional outcome nor patient satisfaction compared to fast-track surgery performed in the Netherlands.

ABSTRACT

INTRODUCTION: Hardware removal preceding total hip arthroplasty may increase the risk of prosthetic joint infection (PJI). Whether hardware removal and total hip arthroplasty (THA) should be performed in a single- or two-stage procedure remains controversial. In this comparative retrospective study, the incidence of PJI following either single- or two-stage THA with hardware removal was assessed in a consecutive series. PATIENTS AND METHODS: All patients that underwent THA preceded by hardware removal from January 2006 until March 2018 were retrospectively reviewed and checked for the occurrence of early PJI. Recognized risk factors for PJI at the time of surgery were evaluated and the incidence of early PJI was compared between one- and two-stage THA regarding hardware removal. RESULTS: 145 patients underwent THA and hardware removal (52 two-stage surgery and 93 single-stage surgery). There were no significant differences between both groups regarding pre-operative hemoglobulin levels, time interval between internal fixation and THA, antibiotic-loaded-cement use, BMI and ASA classification. Overall the incidence of early PJI was 6.9%. The incidence of PJI was 8.6% in the single-stage group versus 3.8% in the two-stage group (P = 0.234). CONCLUSION: Irrespective of single- or two-stage procedures, a high incidence of PJI was encountered. Despite non-significance, a trend towards a higher proportion of patients developing PJI after single-stage surgery was encountered. We recommend a two-stage surgical procedure regarding hardware removal and THA in patients that are expected to tolerate this surgical strategy. When considering a one-stage procedure, it should be preceded by a thorough pre-operative workup including joint aspiration and serum determination of inflammatory parameters. Multiple tissue samples should be obtained during hardware removal in either one- or two-stage procedures since the risk for development of PJI is relevant.

ABSTRACT

STUDY DESIGN: Retrospective, single centre cohort study. OBJECTIVES: To determine factors associated with ventilator weaning success and failure in patients with acute spinal cord injury (SCI); determine length of time and attempts required to wean from the ventilator successfully and determine the incidence of pneumonia. SETTING: BG Klinikum Hamburg, Level 1 trauma centre, SCI Department, Germany. METHODS: From 2010 until 2017, 165 consecutive patients with cervical SCI, initially dependent on a ventilator, were included and weaned discontinuously via tracheal cannula. Data related to anthropometric details, neurological injury, respiratory outcomes, and weaning parameters were prospectively recorded in a database and retrospectively analysed. RESULTS: Seventy-nine percent of all patients were successfully weaned from ventilation. Average duration of the complete weaning process was 37 days. Ninety-one percent of the successfully weaned patients completed this on first attempt. Age (>56 years), level of injury (C4 and/or above), vital capacity (<1500 ml), obesity (>25 kg/m2), and chronic obstructive pulmonary disease (COPD) significantly decreased the chance of successful weaning. These factors also correlated with a higher number of weaning attempts. High level of injury, older age, and reduced vital capacity also increased the duration of the weaning process. Patients with low vital capacity and concurrent therapy with Baclofen and Dantrolene showed higher rates of pneumonia. CONCLUSIONS: We conclude that mentioned factors are associated with weaning outcome and useful for clinical recommendations and patient counselling. These data further support the complexity of ventilator weaning in the SCI population due to associated complications, therefore we recommend conducting weaning of patients with SCI on intensive or intermediate care units (ICU/IMCU) in specialised centres.
