A clinical guide to the medial ligaments of the ankle: Anatomy, function, diagnosis of injuries and treatment of instability-a narrative review.

BACKGROUND: The aim was to provide an update on anatomy and function of the medial ankle ligaments, diagnosis of their injuries and treatment of medial ankle instability. METHODS: Literature search on PubMed. RESULTS: Injuries to the deltoid ligament are not uncommon in relation to malleolar fractures and ankle sprains. Chronic instability may lead to ankle osteoarthritis. However, there is no consensus on diagnostic criteria (clinically, by imaging and by arthroscopy), on indications for non-operative and operative treatment, and on standards for repair and reconstruction of the ligament complex. There is no current evidence to support acute repair of deltoid ligament injury. Reports on the effect of isolated deltoid ligament reconstruction are very sparse. CONCLUSION: There is a need for a focused effort to establish evidence for all aspects of deltoid ligament injury.

Circulating Tumor DNA Analysis in Advanced Urothelial Carcinoma: Insights from Biological Analysis and Extended Clinical Follow-up.

PURPOSE: To investigate whether circulating tumor DNA (ctDNA) assessment in patients with muscle-invasive bladder cancer predicts treatment response and provides early detection of metastatic disease. EXPERIMENTAL DESIGN: We present full follow-up results (median follow-up: 68 months) from a previously described cohort of 68 neoadjuvant chemotherapy (NAC)-treated patients who underwent longitudinal ctDNA testing (712 plasma samples). In addition, we performed ctDNA evaluation of 153 plasma samples collected before and after radical cystectomy (RC) in a separate cohort of 102 NAC-naïve patients (median follow-up: 72 months). Total RNA sequencing of tumors was performed to investigate biological characteristics of ctDNA shedding tumors. RESULTS: Assessment of ctDNA after RC identified metastatic relapse with a sensitivity of 94% and specificity of 98% using the expanded follow-up data for the NAC-treated patients. ctDNA dynamics during NAC was independently associated with patient outcomes when adjusted for pathologic downstaging (HR = 4.7; P = 0.029). For the NAC-naïve patients, ctDNA was a prognostic predictor before (HR = 3.4; P = 0.0005) and after RC (HR = 17.8; P = 0.0002). No statistically significant difference in recurrence-free survival for patients without detectable ctDNA at diagnosis was observed between the cohorts. Baseline ctDNA positivity was associated with the Basal/Squamous (Ba/Sq) subtype and enrichment of epithelial-to-mesenchymal transition and cell cycle-associated gene sets. CONCLUSIONS: ctDNA is prognostic in NAC-treated and NAC-naïve patients with more than 5 years follow-up and outperforms pathologic downstaging in predicting treatment efficacy. Patients without detectable ctDNA at diagnosis may benefit significantly less from NAC, but additional studies are needed.

[Combination of a Lisfranc injury and a dislocation of the proximal tibiofibular joint].

Lisfranc injuries and dislocations of the proximal tibiofibular joint are both rare and frequently missed on initial examination. However, delayed treatment can lead to chronic instability. This is a case report of a 26-year-old man, who received both of these injuries on the same extremity from a collision during a basketball game. The dislocation of the proximal tibiofibular joint was treated with closed reduction, however the Lisfranc injury required open reduction and internal fixation. At the follow-up after ten weeks, the patient was doing well and started rehabilitation.
