Combined Anterior Cruciate Ligament and Anterolateral Ligament Reconstruction Using a Single Peroneus Longus Tendon Graft.

The peroneus longus tendon seems a viable graft option for knee ligament reconstructions, with adequate biomechanical properties and low morbidity after harvesting. The objective of this article is to describe a combined anterior cruciate ligament and anterolateral ligament reconstruction technique using a single peroneus longus tendon graft harvested from the infra malleolar region to ensure sufficient length.

Cavus Foot Correction Using a Full Percutaneous Procedure: A Case Series.

Cavus foot is a tri-planar deformity that requires correction in several bones and soft tissue. Minimally invasive surgeries are less aggressive, faster and easier to recover from. Here, we describe the initial results of a technique for percutaneous cavus foot correction.

Talar Body Reconstruction for Nonunions and Malunions.

Background: Talar body and neck nonunions and malunions may undergo a reconstructive surgery when joint cartilage is still viable, and no talar collapse or infection has occurred. This is a rare condition and the studies supporting the procedure have small number of cases. The objective of the present study is to report a case series of six patients who underwent talar reconstructions.

Mind the gap between the fracture line and the length of the working area: a 2-D finite element analysis using an extramedullary fixation model.

Objective: To determine the ideal working area for a simple transverse fracture line treated with a bridge plate.

Methods: A 2-D finite element analysis of a hypothetical femur was performed for the quantitative evaluation of a large-fragment titanium alloy locking plate based on the precept of relative stability in a case of a simple transverse diaphyseal fracture. Two simulations (one case of strain and another case of stress distribution) were analyzed in three unique situations according to the von Mises stress theory.

Minimally invasive posteromedial percutaneous plate osteosynthesis for diaphyseal tibial fractures: technique description.

Purpose: The aim of this study was to evaluate the feasibility of performing minimally-invasive plate osteosynthesis (MIPO) in tibial fractures using two posteromedial incisions, and to measure the distance between the plate and neurovascular structures.

Materials And Methods: We performed nine dissections of specimens that were submitted to tibial MIPO with two posteromedial incisions. One locking compression plate (LCP) of 14 to 16 holes was inserted into the submuscular tunnel in a retrograde manner.

EPIDEMIOLOGICAL STUDY ON LISFRANC INJURIES.

Objective: To analyze the characteristics of patients with Lisfranc injuries and their associated fractures

Methods: This is a retrospective analysis on 42 patients with Lisfranc injuries hospitalized at Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Faculdade de Medicina da Universidade de São Paulo, between 2006 and 2010. Parameters on patient profile, risk factors, fracture characteristics, data on treatment and acute complications were analyzed

Results: Analysis of 42 cases showed that in our sample, men were more affected than women, with a ratio of 4.25:1.

Charcot neuroarthropathy: realignment of diabetic foot by means of osteosynthesis using intramedullary screws - case report.

Diabetes mellitus is a serious disease that affects a large portion of the population. Charcot neuroarthropathy is one of its major complications and can lead to osteoarticular deformities, functional incapacity, ulcers and ankle and foot infections. Realignment of the foot by means of arthrodesis presents a high rate of implant failure due to weight-bearing on an insensitive foot.

Epidemiological study on talus fractures.

Objective: to analyze the characteristics of patients with talus fractures and the injuries that they present.

Methods: retrospective analysis on patients hospitalized in the Institute of Orthopedics and Traumatology, Hospital das Clínicas, School of Medicine of the University of São Paulo, between 2006 and 2011, with talus fractures. Patient profile parameters, risk factors, fracture characteristics, treatment data and acute complications were analyzed.

Epidemiologic study of ankle fractures in a tertiary hospital.

Objectives: To evaluate the epidemiology of ankle fractures surgically treated at the Instituto de Ortopedia e Traumatologia do Hospital das Clínicas da Universidade de São Paulo.

Methods: Medical records of patients admitted with foot and ankle fractures between 2006 and 2011 were revised. Seventy three ankle fractures that underwent surgical treatment were identified.

Hállux Rígidus: prospective study of joint replacement with hemiarthroplasty.

Objective: To report the results of medium-term follow-up after deploying Arthrosurface-HemiCap((r)) in patients with diagnosis of Hállux Rigidus (HR).

Method: Eleven patients underwent partial Arthroplasty of the first metatarsal-phalangeal joint. Six women and five men with an average age 51.

Malignant Fibrohisticytoma of the Knee in a Patient with HIV.

This case report describes a patient presenting with anterior knee pain (extensor mechanism pain), a poorly studied complaint in the HIV population. The final diagnosis was malignant fibrohistiocytoma, a rare condition among knee pathologies, successfully treated with endoprosthesis after tumor resection. This article focuses on what the authors learned after treating this patient, particularly on the difficulty in making a correct diagnosis of this group of patients due to lack of adequate epidemiological characterization.

Osteopenia and osteoporosis in people living with HIV: multiprofessional approach.

Increasing bone mineralization abnormalities observed among people living with HIV (PLWHIV) result from various factors relating to the host, the virus, and the antiretrovirals used. Today, HIV infection is considered to be a risk factor for bone mineralization disorders. The test most recommended for diagnosing osteoporosis is measurement of bone mineral density by means of dual energy X-ray absorptiometry at two sites.

Osteoarticular complications related to HIV infection and highly active antiretroviral therapy.

With the significant increase in life expectancy for HIV-infected patients in the era of high potency antiretroviral therapy, major metabolic changes have been observed due to the prolonged period of the viral infection and the treatment itself. Osteoarticular changes resulting from these processes are mainly reported in long term HIV-infected patients receiving high potency antiretroviral therapy and include osteopenia/osteoporosis, osteonecrosis, carpal tunnel syndrome and adhesive capsulitis of the shoulder.
