Anchorless Onlay Dynamic Anterior Stabilization of the Shoulder Using a Guided Posterior Double Endobutton Fixation.

The treatment of shoulder instability in the presence of a subcritical glenoid defect poses challenges, as simple Bankart seems insufficient, and the Latarjet procedure may be excessive. Recently, a dynamic anterior stabilization technique involving anterior transposition of the long head of the biceps (LHB) through a subscapularis split was described for that purpose. Previously published results demonstrated good short-term results, but several technical pitfalls have also been mentioned. We describe an onlay, anchorless, and intra-articular knotless method of fixing the LHB into the anterior glenoid that provides the important stabilizing "sling effect" of the dynamic anterior stabilization while avoiding some of the pitfalls described by other techniques.

[Consecutive Ankle Sprain Classification and Injury Systematization (CASCaIS), A New Lateral Ankle Sprain Classification Based on the Pivot Test: A Prospective Cohort Study]. / Consecutive Ankle Sprain Classification and Injury Systematization (CASCaIS), Uma Nova Classificação de Entorse Lateral do Tornozelo Baseada no Teste de Pivot: Estudo Prospetivo de Coorte.

INTRODUCTION: The biggest challenge in the treatment of acute ankle sprain is the uncertainty of the prognosis. The traditional classifications have several interpretations and little correlation with prognosis. In this study we propose a new classification for acute ankle sprain only based on clinical criteria. MATERIAL AND METHODS: We prospectively evaluated all patients with an ankle sprain, aged between 18 and 45 years, admitted to a hospital during a 24 month period. The minimum follow-up period was 12 months. The sprains were classified, in the first few days (CASCaIS-Initial), according to autonomous gait capacity, inspection and palpation. After a few weeks (CASCaIS-Deferred), it was complemented with the mechanical evaluation of ligaments through the ankle pivot test. RESULTS: Among the 49 patients who completed the follow-up, none of those who had a pivot-negative test progressed to chronic ankle instability (CAI). Nine of the 33 patients (27%) with a positive pivot progressed to CAI (p = 0.022). The evaluation of CASCaIS-Deferred demonstrated an association with CAI (p = 0.018). CONCLUSION: This classification proved to be a simple, inexpensive, and reliable tool that clinicians can use to determine the prognosis of the sprain.

Introdução: O maior desafio no tratamento da entorse aguda do tornozelo é a indefinição do prognóstico. As classificações clássicas têm várias interpretações e pouca correlação com o prognóstico. Com este trabalho propomos uma nova classificação baseada apenas em critérios clínicos.Material e Métodos: Foram prospectivamente avaliados doentes entre os 18 e os 45 anos com entorse aguda do tornozelo, admitidos numa instituição durante 24 meses. O seguimento mínimo teve uma duração de 12 meses. Estes doentes foram classificados nos primeiros dias após a entorse (CASCaIS-Inicial) com base na valorização da capacidade de marcha autónoma, inspeção do quadro inflamatório e palpação. Passadas algumas semanas (CASCaIS-Diferida) complementou-se com a avaliação ligamentar pelo teste de pivot do tornozelo.Resultados: Dos 49 doentes que completaram o seguimento, nenhum dos que tinha um teste pivot-negativo evoluiu para instabilidade crónica do tornozelo (ICT). Nove dos 33 doentes (27%) com um pivot-positivo evoluíram para ICT (p = 0,022). A avaliação da CASCaIS-Diferida demonstrou uma associação com a ICT (p = 0,018).Conclusão: Esta classificação demonstrou ser uma ferramenta simples, não dispendiosa e fiável que os clínicos poderão usar para determinar o prognóstico da entorse.

Chronic ankle instability has no correlation with the number of ruptured ligaments in severe anterolateral sprain: a systematic review and meta-analysis.

PURPOSE: Despite being a significant public health problem, ankle sprains' prognostic factors are largely unknown. This review aimed to systematically analyze the literature on acute ankle sprains to compare the prognosis of a combined anterior talofibular (ATFL) and calcaneofibular (CFL) ligaments rupture with an isolated ATFL rupture in terms of progression to chronic ankle instability and other clinical outcomes. METHODS: The databases for Pubmed, CENTRAL and Web of Science were searched. Clinical studies reporting the prognostic effect of combined ATFL-CFL rupture versus an isolated ATFL rupture in conservatively treated ankle sprains, with a minimum follow-up of 12 months, were eligible for inclusion. Only studies with a reliable diagnostic method for anterolateral ankle ligaments evaluation, namely ultrasonography, magnetic resonance imaging, arthrography or stress tenography, were included. The relative risk (RR), along with the 95% confidence interval (CI), was used to quantitatively analyze the main outcomes. RESULTS: Nine papers were selected for inclusion, of which five were suitable for quantitative analysis. None of them found a statistically significant correlation between ligament injury severity and progression to chronic instability. Concerning other clinical outcomes, three studies found a statistically significant correlation between a combined ligament injury and a worse clinical prognosis. From the quantitative analysis, the relative risk (RR) of chronic ankle instability in a single versus a combined ligament rupture showed no significant difference. CONCLUSION: A significant statistical correlation between a combined ATFL-CFL rupture and chronic ankle instability, compared to an isolated ATFL rupture, was not found. There is, however, fair evidence showing a worse clinical outcome score in the combined ruptures, as well as a decreased return to full sports activities. The use of reliable and accessible diagnostic methods to determine the number of ruptured ligaments might have a role in managing severe ankle sprains. LEVEL OF EVIDENCE: Level III.

Schwannoma of the First Webspace: A Case Report.

CASE: A 65-year-old man presented with plantar foot pain associated with a mass in the first webspace. A Morton neuroma was considered the probable diagnosis. Despite nonoperative treatment the pain continued. Surgical excision was performed, and histology was interpreted as a schwannoma. Symptoms resolved after surgery. CONCLUSION: Schwannoma of the foot is a rare condition, and to the best of our knowledge, this is the first case reported in the first webspace. Definitive treatment and diagnosis is surgical excision. Surgeons should consider schwannomas in the differential diagnosis of plantar foot pain because this can be misdiagnosed as a Morton neuroma.
