Acromion clavicular joint reconstruction with LArS ligament in acute dislocation
Background: The acromion clavicular joint dislocations are common injuries of the shoulder. The severity is dependent upon the degree of ligamentous injury. Surgical treatment is typically performed in higher grade acromioclavicular separation with several static and dynamic operative procedures with or without primary ligament replacement. Methods: 47 patients with acute Rockwood type III, IV, and V injuries were treated surgically with LARS reconstruction. The success of technique was evaluated by radiographic outcomes for each patient at every follow-up visit (one,three, 12 months), while to assess pain reduction and clinical evaluation Visual Analogue scale score (VAS) and Constant-Murl…
Cardiac risk stratification in elective non-cardiac surgery: Role of NT-proBNP
AIM: The aim of the study was to investigate the utility of NT-proBNP measurement for the stratification of presurgical cardiac risk. METHODS: Cardiac risk before elective non-cardiac surgery was evaluated in 82 consecutive patients. From each patient a venous blood sample was drawn to determinate NT-proBNP levels. Patients were followed up over three months in order to detect the occurrence of cardiac adverse events. RESULTS: NT-proBNP was positively correlated (P<0.0001) with age, days of hospitalization (P=0.001) and ASA class (P=0.001). High surgical risk (P<0.0001), diabetes (P=0.004), dyslipidemia (P=0.006) and elevated levels of NT-proBNP (P<0.0001) were significantly correlated with…
Bleeding in orthopaedic surgery: The role of blood transfusion and erythropoietin alpha
High energy trauma is often responsable for acute bleeding. Long bone and pelvis fractures are correlated with increased blood loss. Hypovolaemia could become a life threatening complication especially in elderly patients because of the reduced physiological response. Furthemore it could compromise the course of associated morbidities. Haemorrage is also associated in both comminuted fractures and osteoporosis. An increased intraoperative bleeding often occurs when a prolonged surgical time is required to obtain an appropriate ostheosynthesis. The final consequence of a major bleeding is hypovolaemic shock. the reduced oxygen tension of the tissue may be responsible for heart attack, arrhyt…
Evolution and healing of fragility fractures of the proximal femur
After a traumatic fracture a physiological process begins to heal the fracture. The steps of the process are inflammation, granulation, formation of fibrous callus and finally bone. There are many factors that may influence the healing of the fracture: adequate blood supply, good contact between bone fragments, good stability of the fracture, general health, age, smoking, related pathology, use of drugs, etc. In elderly patients the variations in bone structure and healing processes have a negative influence on fracture healing. Fragility fractures require careful placement of the implants to reduce the risk of failure of osteosynthesis. Appropriate surgical devices and facilitation factors…
