Third-Generation Minimally Invasive Chevron Akin Osteotomy for Hallux Valgus: Three-Year Outcomes.

Introduction: Numerous minimally invasive techniques have been developed for Hallux Valgus in recent years. Third-generation Minimally Invasive Chevron Akin (MICA) osteotomy has shown promising early results, but longer-term follow-up is required to assess whether patient clinical and radiological improvement is sustained. This cohort study presents three-year follow-up outcomes for patients of a single surgeon case series. Methods: Thirty-three patients underwent third-generation MICA surgery between 2017 and 2018. Patient clinical-reported outcome measures included American Orthopaedic Foot & Ankle Society (AOFAS), Manchester-Oxford Foot Questionnaire (MOXFQ) scores, and Coughlin satisfaction. Radiographic outcomes were evaluated after a period of three years using hallux valgus angle (HVA) and inter-metatarsal angle (IMA), and compared to pre- and early post-operative outcomes. Results: At 36 months, mean AOFAS scores improved from 48.2 to 95.6, mean MOXFQ scores improved from 57.6 to 6.7. Using the Coughlin scale, 81.8% of patients rated their outcome as 'Excellent' and 18.2% as 'Good'. Radiographic outcomes showed HVA and mean IMA decreased from 34.6 degrees to 16.0 degrees and from 13.1 to 6.1, respectively at 36 months. Conclusion: Third-generation MICA demonstrates promising patient satisfaction scores post-operatively, and we have shown these improvements are sustained over a minimum three-year follow-up period. Level of Evidence: Level IV, case series.

Missed lateral end clavicle fracture in adolescent patients: The value of undertaking additional clavicle radiographic views.

Clavicle fractures are extremely common, accounting for 5%-10% of all pediatric fractures. Due to the increased radiation dose, additional radiographic views are less frequently performed, particularly in skeletally immature patients. In Trauma and Orthopedic practice, it is well known that 2 radiographic views are essential for any fracture assessment, with additional views such as oblique views for selected cases. Oblique views are recommended, especially for extremity trauma as this has shown to reduce the incidence of missed diagnoses. Although 2 views of the clavicle, A-P and 45° cephalic tilt are recommended, it is the usual practice in most radiology departments to undertake A-P view of clavicle only. We report a case of a lateral end displaced clavicle fracture in a 16-year-old sustained following football injury. This was completely missed at the initial encounter and the patient later presented with pain and difficulty to move his right shoulder. We believe if this patient had a 45° cephalic tilt view at the time of presentation, the fracture would have been identified and appropriate treatment would have been instituted. Awareness of obtaining a minimum of 2 radiographic views for lateral clavicle fractures will reduce the incidence of missed clavicle fractures.

A Systematic Review of Open and Minimally Invasive Surgery for Treating Recurrent Hallux Valgus.

Background Despite advancements in primary correction of hallux valgus (HV), significant rates of reoperation remain across common techniques, with complications following primary correction up to 50% according to some studies. 1 This study explored different methods of surgery currently used in treating HV recurrence specifically (for which literature on the subject has been limited), evaluating open and adapted minimally invasive surgical (MIS) primary techniques used for revision. Methods In December 2020, literature search for both open and MIS surgical techniques in HV revision was conducted using PubMed, EMBASE, and MEDLINE library databases. Results and Conclusion Of initial 143 publications, 10 were finally included for data synthesis including 273 patients and 301 feet. Out of 301 feet, 80 (26.6%) underwent revision with MIS techniques (involving distal metatarsal osteotomies). Those undergoing grouped MIS revisions had an average improvement of 38.3 in their American Orthopaedic Foot and Ankle Society score, compared to 26.8 in those using open techniques. Revision approaches using grouped MIS techniques showed a postoperative reduction in intermetatarsal angle and HV angle of 5.6 and 18.4 degrees, respectively, compared to 15.5 and 4.4 degrees, respectively, for open techniques. There are, however, limitations in the current literature on MIS techniques in revision HV surgery specifically. MIS techniques grouped did not show worse outcomes or safety concerns compared to open techniques.

Closed midshaft clavicle fractures : an evidence-based triage management algorithm.

AIMS: The management of mid-shaft clavicle fractures (MSCFs) has evolved over the last three decades. Controversy exists over which specific fracture patterns to treat and when. This review aims to synthesize the literature in order to formulate an appropriate management algorithm for these injuries in both adolescents and adults. METHODS: This is a systematic review of clinical studies comparing the outcomes of operative and nonoperative treatments for MSCFs in the past 15 years. The literature was searched using, PubMed, Google scholar, OVID Medline, and Embase. All databases were searched with identical search terms: mid-shaft clavicle fractures (± fixation) (± nonoperative). RESULTS: Using the search criteria identified, 247 studies were deemed eligible. Following initial screening, 220 studies were excluded on the basis that they were duplicates and/or irrelevant to the research question being posed. A total of 27 full-text articles remained and were included in the final review. The majority of the meta-analyses draw the same conclusions, which are that operatively treated fractures have lower nonunion and malunion rates but that, in those fractures which unite (either operative or nonoperative), the functional outcomes are the same at six months. CONCLUSION: With regard to the adolescent population, the existing body of evidence is insufficient to support the use of routine operative management. Regarding adult fractures, the key to identifying patients who benefit from operative management lies in the identification of risk factors for nonunion. We present an algorithm that can be used to guide both the patient and the surgeon in a joint decision-making process, in order to optimize patient satisfaction and outcomes.Cite this article: Bone Jt Open 2022;3(11):850-858.

Correlations of morphological features and surgical management with clinical outcome in a multicentre study of 241 phyllodes tumours of the breast.

AIMS: Phyllodes tumours (PTs) represent an unusual but complex group of breast lesions with a tendency to recur locally and, less commonly, metastasise. On core biopsies, their appearances can be difficult to discriminate from those of other fibroepithelial lesions, which may compromise their surgical management. The aims of this study were to assess the preoperative diagnosis of PTs and to evaluate the impacts of surgical management and morphological features on their behaviour. METHODS AND RESULTS: We combined datasets from three centres over two decades, including core biopsies, excision specimens, and follow-up. Core biopsy results were compared with final excision specimens. The relationships of surgical procedure and morphological features with local recurrence (LR) and metastasis were assessed. Two hundred and forty-one PTs were studied. Core biopsy resulted in a diagnosis of possible or definite PT in 76% of cases. Malignant tumours were more likely to be larger, occurred at an older age, and were surgically more challenging, with difficulties being encountered in achieving negative margins. There were 12 cases (5%) that showed LR alone, and another six cases (2.5%) that had distant metastases. Morphological features associated with adverse outcome were grade of PT, increased mitotic counts, necrosis, infiltrative margins, stromal atypia, and heterologous components. Both LR and metastatic behaviour correlated with larger size and distance to margins. CONCLUSIONS: Our results suggest that excision margins have a significant impact on LR of PT, whereas metastatic behaviour is influenced by tumour biology. We add to the evidence base on histological features of tumours that contribute to long-term outcomes of PT patients.
