[Venous thromboembolism prophylaxis in major orthopaedic surgery: A multicenter, prospective, observational study].

Objectives: We investigated risk factors for venous thromboembolism (VTE), prophylaxis measures employed, and incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing major orthopaedic surgery (MOS).

Methods: An open, multicenter, prospective, observational study was conducted in 21 medical centers, comprising 899 patients. Of these, 316 patients (35.

Minimally invasive treatment of simple bone cysts with percutaneous autogenous bone marrow injection.

Percutaneous autogeneic bone marrow injection is an effective method for managing simple bone cysts, and it might be considered before the application of more extensive procedures.

Primary echinococcus infestation of the bone and muscles.

Hydatid diseases of the bone and muscles are rare, generally are incurable, and have a high level of recurrence. We attempted to ascertain whether the recurrence rate decreased in patients with hydatid disease infestation of the bone and skeletal muscle who were treated with current surgical techniques and antihelminthic chemotherapy, and whether the outcomes for bone infestation were different when compared with outcomes for muscular infestation. We retrospectively reviewed 15 patients with hydatid disease of the bone (eight patients) and muscle (seven patients).
