Despite the recent advances in imaging technologies, there is still a need for more information about the degree of joint degeneration and changes of the collagen content of tendons to select the proper implant type. It is known that human long head biceps tendon subjected to synovial inflammation and mechanical wear could result in tear and structural damage. Differential scanning calorimetry has already been demonstrated to be a dependable in the assessment of collagen in degenerative tendon conditions. The purpose of the study was to determine whether variations in thermal parameters detected by DSC are related to the degenerative changes of LHBT samples. LHBT tendons were collected from patients who had reversed shoulder arthroplasty because of trauma. DSC was utilized to measure the thermodynamic changes. Macroscopical, radiological and histological assessment were also performed. Based on the thermal parameters and denaturation curves, LHBT samples collected of patients underwent reversed shoulder arthroplasty due to comminuted proximal humerus fracture have shown minimal or mild degenerative injuries. These data were supported by preoperative radiological examination and histological analysis. The authors suggest that DSC could be a useful investigative tool in the clinical evaluation of tendon injuries.

Patients treated with small and large joint septic inflammations or with periprosthetic joint infections (PJI) were entered into the study. Demographics, microbiological cultures and inflammatory mediators were evaluated.Between 2012 and 2016, total of 1116 hip and 241 knee surgeries were performed at our Department in relation to prostheses; including primary and revision arthroplasties and further surgeries due to PJI. During this period, 72 patients were operated with large joints infections or PJI and another 65 patients were treated due to small joint infections.The main outcome of interest was to evaluate the sensitivity of conventional microbiological cultures in the primary diagnostics of joint and periprosthetic infections.The most frequent bacteria strains were the Staphylococci: in 43 cases (22.16%) Staphylococcus aureus, in 22 cases (11.34%) coagulase-negative Staphylococcus, in 3 cases (1.54%) Staphylococcus epidermidis and in 4 cases (2.06%) methicillin-resistant S. aureus (MRSA) were detected. In 30 cases (21.88%), the primary microbiological investigation could not reveal the presence of bacteria.Based on our data, the efficacy of conventional microbiological testing in the diagnostics of different type of joint infections is questionable. Therefore, further studies are warranted to evaluate the efficacy of novel diagnostic testing tools in prospective randomized controlled trials.

Comprehensive analysis of the Hungarian nationwide health insurance database.Data of in-patient records with S7200 ICD-10 codes were collected from the Hungarian National Health Insurance Fund Administration (HNHIFA) and from the health care provider institutes. The patients with femoral neck fractures in the year of 2000, following reduction and internal fixation aged 60 years or older were evaluated. The secondary, non-prosthetic fracture related treatments during the 8 year follow-up period were registered.Of the prognostic factors, age, gender, type of fracture, season and day of the primary surgery, length of waiting time to the operation and the accompanied diseases were evaluated as risk factors for all type of fracture-related further interventions, with the exception of arthroplasties.A total of 2895 patients with intracapsular femoral neck fractures met the study criteria. The mean age was 77.96 years (SD: 8.54). The cohort of the patients was observed for a total of 10,077.8 person-years. The non-prosthetic fracture related treatment was performed in 265 patients (9,2%); the median of the time elapsed to the secondary definitive treatment was 3.5 months. With Cox regression analysis, significant correlation was revealed between the incidence of non-prosthetic treatment and younger age (year, HR = 0.977, p = 0.002), surgical delay (12-24 h vs 0-6 h, HR = 1.518, p = 0.023; 24h+ vs 0-6 h, HR = 1.372, p = 0.050), season of primary osteosynthesis (fall vs summer, HR = 0.636, p = 0.012), and type of femoral neck fracture (intracapsular displaced vs intracapsular undisplaced, HR = 1.340, p = 0,047). There was no significant effect of the day of primary surgery, the gender and the presence of co-morbidities on the incidence of further surgical interventions.The summertime primary surgical intervention, delay of surgery longer than 12 h and type of femoral neck fracture are independent predictors of non-prosthetic further treatment of femoral neck fractures in elderly patients.Level IV, evidence from cohort studies.
