the aim of this study is to compare three modes of femoral fixation, namely aperfix, rigidfix and endobutton, in anterior cruciate ligament (acl) reconstruction. 120 patients were randomly assigned to three groups, each consisting of 40 patients, and each group was treated by one of the above mentioned methods of femoral fixation. all patients were examined prior to and 24 months after surgery,...

Background: Several studies suggest that patients infected with the human immunodeficiency virus (HIV) under highly active antiretroviral therapy (HAART) have a higher cardiovascular risk than general population. Arterial stiffness is an independent predictor of events and can be measured through carotid-femoral pulse wave velocity (PWV). The objectives this study were to characterize sample HI...

Coccygeal herniation after coccygectomy is rare. Little is known about the management of this complication. We present a case of a 44 year old women with a coccygeal herniation 7 years after coccygectomy. She was treated two times for an infected pilonidal sinus with incision and drainage. After the last incision and drainage she had complaints of a painful swelling in the sacral area and diffi...

Two-stage total hip arthroplasty (THA) is considered a safe choice for the treatment of primary infectious arthritis of the hip. In cases where the proximal portion of the femur is intact without infection, the use of a spacer with a femoral stem during the interim would disturb the normal femoral medullary cavity. The authors report the technical procedure and outcomes of cases using a novel m...

We have designed a modular cemented femoral component for revision of failed total hip arthroplasty in which deficiency of the proximal femur is such as to require a variable extrafemoral portion of the stem. We present the results of the first 74 operations in 72 patients; 56 of the patients had grade-3 or grade-4 femoral deficiency as defined by Gustilo and Pasternak and 24 had fractures of t...

In this paper, psuedo random binary sequences are generated from the “Chaos Based Key Stream Generator- using novel Permutation technique with two dimensional patterns and substitution Z4 mapping” investigation of auto correlation property for seuwnces is presented. Initially a chaotic function, considering Logistic map used to generate Pseudo Random Numbers (PRNs). Then these numbers converted...

BACKGROUND Revascularization alternatives for patients with critical limb ischemia and without adequate autogenous vein remain challenging. We reviewed our experience with the use of arterial homograft as a conduit for limb salvage in patients with limb ischemia and active lower extremity infections. METHODS A retrospective review of patients who underwent open arterial revascularization of t...
