Reliability of forced internal rotation and active internal rotation to assess lateral instability of the biceps pulley.

Purpose: the aim of this study was to investigate the relationship between positive painful forced internal rotation (FIR) and lateral pulley instability in the presence of a pre-diagnosed posterosuperior cuff tear. The same investigation was conducted for painful active internal rotation (AIR).

Methods: a multicenter prospective study was conducted in a series of patients scheduled to undergo arthroscopic posterosuperior cuff repair.

Minimally invasive retrocapital osteotomy of the first metatarsal in hallux valgus deformity.

Objective: Percutaneous retrocapital distal osteotomy of the first metatarsal for surgical treatment of hallux valgus.

Indications: Mild to moderate hallux valgus deformity in both juveniles and adults. Recurrent hallux valgus deformity after previous surgery.

Evaluation of cardiac involvement following major orthopedic surgery.

Background: Cardiovascular morbidity is frequent after non-cardiac surgery and the early recognition of cardiac involvement is an essential tool for clinical risk stratification and management. The aim of this study was to investigate the behavior of traditional and emerging cardiac markers, including NT-prohormone-brain natriuretic peptide (NT-proBNP) and ischemia-modified albumin (IMA), in the perioperative period in patients undergoing major uncomplicated orthopedic surgery.

Methods: A total of 37 patients undergoing major orthopedic surgery were longitudinally evaluated for NT-proBNP, IMA, cardiac troponin T (cTnT), creatine kinase isoenzyme MB and myoglobin 3 h before surgery and 4 and 72 h thereafter.
