Open Reduction and Internal Fixation Versus Primary Arthrodesis for the Treatment of Acute Lisfranc Injuries: A Systematic Review and Meta-analysis.

This study aims to compare outcomes of open reduction and internal fixation (ORIF) and primary arthrodesis in management of Lisfranc injuries. In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement standards, a systematic review was carried out. MEDLINE, EMBASE, CINAHL, and the Cochrane Central Register of Controlled Trials were searched to identify both randomised controlled trials (RCTs) and nonrandomised studies comparing the outcomes of ORIF and primary arthrodesis for Lisfranc injuries. Random- and fixed-effect statistical models were applied to calculate the pooled outcome data. Two RCTs and 3 observational studies were identified, compiling a total of 187 subjects with acute Lisfranc injuries and a mean follow-up duration of 62.3 months. Our results demonstrate that ORIF is associated with a significantly higher need for revision surgery (odds ratio [OR] 6.37, 95% confidence interval [CI] 2.68 to 15.11, p < .0001) and a significantly higher rate of persistent pain (OR 6.29, 95% CI 1.07 to 36.89, p = .04) compared with primary arthrodesis. However, we found no significant difference between the groups in terms of visual analogue scale pain score, American Orthopaedic Foot & Ankle Society functional score, or rates of infection. Separate analysis of RCTs showed that ORIF was associated with a more frequent need for revision surgery (OR 17.56, 95% CI 5.47 to 56.38, p < .00001), higher visual analogue scale pain score (mean difference 2.90, 95% CI 2.84 to 2.96, p < .00001), and lower American Orthopaedic Foot & Ankle Society score (mean difference -29.80, 95% CI -39.82 to -19.78, p < .00001). The results of the current study suggest that primary arthrodesis may be associated with better pain and functional outcomes and lower need for revision surgery compared with ORIF. The available evidence is limited and is not adequately robust to make explicit conclusions. The current literature requires high-quality and adequately powered RCTs.

Single incision lateral release for hallux valgus using a cervical biopsy blade: A cadaveric study.

The role of lateral release is widely accepted and regarded as a key step in the management of hallux valgus. There remains however debate in the literature in regards to which structures should be divided and the method of approach. As such, a technique of lateral release using a curved blade placed inferior to the metatarsal head to divide the lateral metatarsosesamoid suspensory ligament and incise the lateral joint capsule has been developed. This technique was performed on fourteen fresh frozen cadaveric specimens which were then dissected. In all cases the lateral metatarsosesamoid suspensory ligament was divided and the lateral capsule incised to the joint line. One case of iatrogenic injury to the oblique head of adductor hallucis tendon was noted. No cases of neurovascular injury were noted. The authors conclude that this method of lateral release to be safe and reproducible in a cadaveric model in achieving lateral release for the management of hallux valgus.

Large-Scale Implementation of Structured Reporting of Adnexal Masses on Ultrasound.

PURPOSE: The aim of this article is to describe the development and implementation of structured reporting of adnexal mass findings on pelvic ultrasound in a large integrated health care delivery system. METHODS: A structured reporting system that includes standardized terminology for describing adnexal masses on ultrasound was developed by a multidisciplinary team of radiologists, gynecologists, and gynecologic oncologists on the basis of literature review and internal data. The system uses a reporting template that requires radiologists to assign abnormal adnexal masses to one of five possible categories on the basis of standardized criteria: category 0, 1, 2, or 3 for masses <10 cm, to reflect increasing concern for malignancy, and category X for masses >10 cm. Unique predefined hashtags were linked to each category to enable electronic data extraction, and a hard stop feature was installed that prevents reports from being finalized without a category designation. In 2014, after a 3-month pilot study, large-scale implementation was supported by an educational campaign consisting of web-based conferences, e-mail announcements, and local presentations. Clinical management recommendations on the basis of category and other clinical factors were provided in a separate practice resource for clinicians. RESULTS: Analysis of adherence revealed that 93% of the approximately 12,000 reports describing abnormal adnexal masses in 2016 included category designations. Feedback from referring providers via an anonymous survey indicated high levels of satisfaction with reports. CONCLUSIONS: Multidisciplinary collaboration and leveraging of technology enabled large-scale implementation of structured reporting with high levels of adherence among radiologists and improved satisfaction among referring providers.

Inter and intra-observer reliability in assessment of the position of the lateral sesamoid in determining the severity of hallux valgus.

BACKGROUND: The position of the lateral sesamoid on standard dorso-plantar weight bearing radiographs, with respect to the lateral cortex of the first metatarsal, has been shown to correlate well with the degree of the hallux valgus angle. This study aimed to assess the inter- and intra-observer error of this new classification system. METHODS: Five orthopaedic consultants and five trainee orthopaedic surgeons were recruited to assess and document the degree of displacement of the lateral sesamoid on 144 weight-bearing dorso-plantar radiographs on two separate occasions. The severity of hallux valgus was defined as normal (0%), mild (≤50%), moderate (51-≤99%) or severe (≥100%) depending on the percentage displacement of the lateral sesamoid body from the lateral cortical border of the first metatarsal. RESULTS: Consultant intra-observer variability showed good agreement between repeated assessment of the radiographs (mean Kappa=0.75). Intra-observer variability for trainee orthopaedic surgeons also showed good agreement with a mean Kappa=0.73. Intraclass correlations for consultants and trainee surgeons was also high. CONCLUSION: The new classification system of assessing the severity of hallux valgus shows high inter- and intra-observer variability with good agreement and reproducibility between surgeons of consultant and trainee grades.

Lateral sesamoid position in hallux valgus: correlation with the conventional radiological assessment.

BACKGROUND: We aimed to quantify the severity of the hallux valgus based on the lateral sesamoid position and to establish a correlation of our simple assessment method with the conventional radiological assessments. METHODS: We reviewed one hundred and twenty two dorso-plantar weight bearing radiographs of feet. The intermetatarsal and hallux valgus angles were measured by the conventional methods; and the position of lateral sesamoid in relation to first metatarsal neck was assessed by our new and simple method. RESULTS: Significant correlation was noted between intermetatarsal angle and lateral sesamoid position (Rho 0.74, p < 0.0001); lateral sesamoid position and hallux valgus angle (Rho 0.56, p < 0.0001). Similar trends were noted in different grades of severity of hallux valgus in all the three methods of assessment. CONCLUSIONS: Our method of assessing hallux valgus deformity based on the lateral sesamoid position is simple, less time consuming and has statistically significant correlation with that of the established conventional radiological measurements.
