Starch as a risk factor for increased trans surgical bleeding in total hip arthroplasty.

Objective: Establish whether the use of starch in hip arthroplasty is a risk factor for excessive surgical bleeding and requirement of red blood cell transfusion.

Method: Analytical observational retrospective study in 240 patients who underwent primary total hip arthroplasty from January 2015 to January 2016. Two groups were formed: starch (94 patients) and non-starch (146 patients).

A prospective randomized trial of total synovectomy versus limited synovectomy in primary total knee arthroplasty: evaluation of bleeding, postoperative pain, and quality of life with SF-12 v2.

Background: During total knee arthroplasty (TKA), total synovectomy (TS) as a part of the surgical technique has been proposed to reduce the inflammatory tissue after the procedure, but there is a controversy about it because of the risk of major postsurgical bleeding. The aim of this study was to compare postoperative bleeding, pain, and health-related quality of life (HRQOL) after a TKA when a TS is performed and when it is not.

Methods: The difference in pre and postoperative hemoglobin was measured, as well as postoperative pain using visual analogue scale (VAS) scores at 24 and 48 h post-surgical, HRQOL was measured prior to surgery and at one year using the SF-12V2 questionnaire.

Risk factors for amputation in periprosthetic knee infection.

Treatment for prosthetic knee replacement is becoming more common. Infection is an arthroplasty-related complication leading to prolonged hospitalization, multiple surgical procedures, permanent loss of the implant, impaired function, impaired quality of life and even amputation of the limb. Previous studies have evaluated the risk factors associated with periprosthetic knee infection, but scarce information related to risk factors associated with amputation in this group of patients is available.

[Sensitivity and antibiotic resistance in infections of the musculoskeletal system].

Background: Infections of the musculoskeletal system are a devastating complication for patients, due to it's long rehabilitation process and even sometimes the removal of the implant, the chronicity of infection, is often due to lack of coverage in empirical antibiotics.

Methods: A retrospective, observational, descriptive cohort study was performed. All cultures form musculoskeletal system infected patients reported of sensitivity and resistance of germs isolated were analyzed.

[Mixed knee arthrodesis a rescue alternative in knee periprosthetic joint infection].

Background: Knee arthrodesis is a rescue procedure for patients with knee periprosthetic joint infection who are not candidates for a revision surgery. The actual methods present a high complication rate with only moderate efectivity.

Methods: We retrospectively analyzed 17 cases, of patients with knee periprosthetic joint infection and bone loss treated by intramedular expandable nail and monoplanar external fixator with a mínimum evolution of 1 year, evaluating the medical records and digitalized X-rays by 2 sub specialized doctors in osteoarticular rescue surgery.

[Clinical and therapeutic approach to Klippel-Feil syndrome in the primary care medicine].

A case of Klippel-Feil syndrome in a female nine years is informed. The patient presented a clinical picture compatible with Klippel-Feil syndrome: short neck with joint movements diminished and low hair implantation. We showed the diagnostics and treatment approach at the primary medicine level, the follow-up until the presence of clinical manifestations of the main clinical problems associated.
