Comparative Study
Cementless total hip arthroplasty with large diameter metal-on-metal heads: short-term survivorship of 8059 hips from the Finnish Arthroplasty Register.
Population-based register data from the National Joint Register of Australia and England and Wales have revealed that the mid-term outcome of cementless large diameter head metal-on-metal total hip arthroplasty is inferior to that of conventional cemented metal-on-polyethylene total hip arthroplasty. The aim of this study was to compare the results of cementless large diameter head metal-on-metal total hip arthroplasty with conventional cemented arthroplasty in Finland. The second aim of this study was to compare the cementless large diameter head metal-on-metal models with each other. ⋯ We found that cementless large diameter head metal-on-metal total hip arthroplasty had short-term survivorship compared with cemented total hip arthroplasty at a nation-wide level. However, in female patients aged 55 years or above, cementless large diameter head metal-on-metal total hip arthroplasty showed inferior results. Furthermore, implant design had an influence on revision rates. Longer follow-up time is needed to assess the success of large diameter head metal-on-metal total hip arthroplasty.

Surgery cancelations cause inappropriate use of hospital resources and additional financial and psychological stress to patients. Cancelation rates have been described to be even more than 10% of scheduled cases. Preoperative anesthesia evaluation clinics have been initialized to decrease cancelation rates. At Hyvinkää hospital, 95% of elective surgical patients are admitted on the morning of operation, and only 25% of these patients visit preoperative anesthesia evaluation clinic prior to surgery. Cancelation rate in Finnish hospitals has not been described. ⋯ Day of surgery cancelation rate was low in same-day admission, although it varied between specialties. Specialties having explicit surgery indications had fewer cancelations than specialties having surgery indications based on more subjective diagnostic. Process improvements need to be considered continuously to further decrease cancelation rate.

Unstable antebrachium diaphyseal fractures in children are nowadays increasingly treated operatively by elastic intramedullary nailing. ⋯ Despite various minor complications, TEN-nailing is considered suitable treatment for unstable forearm shaft fractures. Most of the problems were related to poor technical performance in nailing.

Necrotizing fasciitis (NF) and gas forming myonecrosis (GFM), both being subtypes of necrotizing soft tissue infection (NSTI), are life threatening conditions sharing certain similarities. Despite the necessity of early and radical surgical debridement in necrotizing infections, the distinction between these entities is of clinical relevance since gas forming myonecrosis in a number of cases results from an underlying abdominal cause and the focus of infection can be missed. This study was to evaluate the incidence and risk factors as well as the mortality rate in patients with NSTI and GFM. ⋯ Thirty patients (17 female, 13 male) with necrotizing fasciitis with a mean age of 55 years (SD 15.5) were included in the study. There was no statistically significant difference between survivors and deceased patients comparing the LRINEC score (n.s.). Patients with necrotizing fasciitis secondarily involving the trunk had a significantly higher mortality rate (OR 11.2; 95% CI=1.7-72.3). In the majority of cases (12 cases), minor skin lesions were identified as the site of origin. Amongst all necrotizing soft tissue infections six patients (female n=3; male n=3) with a mean age of 61.5 years (SD 12.2) with non-clostridial gas forming myonecrosis were identified. Three patients had a history of malignancy and in three patients the infection was secondary to major surgery. The mean LRINEC score was 8.5 (SD 1). Three patients (50%) died due to GFM. Early diagnosis and appropriate intervention is critical to provide accurate treatment decisions. Eradicating the differing primary sources of infection in GFM and NF will have a positive impact on outcome.
