Osteochondrolipoma of the foot treated by surgical excision: a case report and literature review.

Background: Osteochondromas, classified as a new benign subtype of lipomas and characterised by chondroid and osseous differentiation, are rare lesions that have been infrequently reported in previous literature. The maxillofacial region was reported as the most frequent localization, with infrequent occurrence in the lower limb. This paper represents the first documented case report of osteochondrolipoma in the foot.

Cross-Cultural Adaptation and Validation of the Arabic Version of the Harris Hip Score.

Background: The Harris Hip Score (HHS) questionnaire has been translated and validated into many languages including Italian, Portuguese, and Turkish but not Arabic. The goal of this study was to translate HHS into the Arabic language with cross-cultural adaptation to include and benefit Arabic speaking communities as it is the most widely used instrument for disease-specific hip joint evaluation and measurement of total hip arthroplasty outcome.

Methods: This questionnaire was translated following a clear and user-friendly guideline protocol.

Traumatic fracture of the polyethylene tibial post and cone in a posterior-stabilized total knee arthroplasty: A case report.

Introduction And Importance: Very few reports addressed polyethylene tibial post and cone fractures requiring revision surgery. Up to our knowledge, this particular pattern of wear, involving 2 fracture areas simultaneously, has not been previously described.

Case Presentation: A 70 year-old female developed a fracture involving both the tibial insert post and cone after a minor trauma after undergoing posterior-stabilized total knee replacement 4 years prior.

Extraarticular Pretibial Synovial Cyst After Arthroscopic Anterior Cruciate Ligament Reconstruction: A Case Report.

Arthroscopic reconstruction of the anterior cruciate ligament has been modernized through new materials and novel surgical techniques. The usage of bioabsorbable screws for tibial fixation may potentially lead to complications, such as formation of a tibial tunnel or pretibial cysts. This is a relatively rare complication, but it has been described in the literature.

INTRAOPERATIVE EVALUATION AND LEVEL OF CONTAMINATION DURING TOTAL KNEE ARTHROPLASTY.

Introduction: Despite numerous articles on intraoperative contamination in total knee arthroplasty (TKA) procedures, the available data on tissue contamination are scarce and mainly based on evaluating bacteriological swabs.

Methods: Two hundred and forty specimens, divided between bone and soft tissue, were obtained from 40 consecutive unilateral primaries TKAs. The specimens were evaluated for aerobic and anaerobic bacterial growth.

Cross-cultural adaptation and validation of the Arabic version of the upper extremity functional index.

Purpose: The purpose of this study was to translate and cross-culturally adapt the UEFI into Modern Standard Arabic language and to examine its psychometric properties among patients with upper extremity musculoskeletal disorders.

Materials And Methods: Translation and cross-cultural adaptation were done following Beaton's guidelines. Internal consistency, test-retest reliability, measurement error and floor and ceiling effects for the Arabic UEFI were tested among 109 patients with upper extremity musculoskeletal disorders.

Total Knee Arthroplasty With Megaprosthesis for Idiopathic Charcot Knee.

Charcot knee is a rare condition with few reported cases in the literature. Although the clinical presentation is highly variable, Charcot knee classically presents with painful arthropathy in addition to instability and decreased range of motion. Herein, we describe the case of a 72-year-old man with idiopathic Charcot knee.

Thromboprophylaxis and mortality among patients who developed venous thromboembolism in seven major hospitals in Saudi Arabia.

Introduction: Venous thromboembolism (VTE) during hospitalization is a serious and potentially fatal condition. Despite its effectiveness, evidence-based thromboprophylaxis is still underutilized in many countries including Saudi Arabia.

Objective Of The Study: Our objectives were to determine how often hospital-acquired VTE patients received appropriate thromboprophylaxis, VTE-associated mortality, and the percentage of patients given anticoagulant therapy and adherence to it after discharged.

Biocompatibility properties of polyamide 6/PCL blends composite textile scaffold using EA.hy926 human endothelial cells.

Enhancing the cytocompatibility profiles, including cell attachment, growth and viability, of designed synthetic scaffolds, has a pivotal role in tissue engineering applications. Polymer blending is one of the most effective methods for providing new desirable biomaterials for tissue scaffolds. This article reports a novel polyamide 6/poly(ε-caprolactone) (PA6/PCL) blends solution which was fabricated to create composite fibrous tissue scaffolds by varying the concentration ratios of PA6 and PCL.

Humeral lateral condyle fractures in children: redefining the criteria for displacement.

The aim of this study is to define paediatric lateral humeral condyle fractures prone to later displacement. The authors reviewed 106 children who were treated surgically for this fracture. There were 74 boys and 32 girls with an age range of 3-10 years.

Randomized clinical trial of continuous femoral nerve block combined with sciatic nerve block versus epidural analgesia for unilateral total knee arthroplasty.

Pain control following total knee arthroplasty (TKA) is crucial to hasten rehabilitation and decrease morbidity. We evaluated whether there is a difference between epidural infusion and continuous femoral nerve block with respect to postoperative pain control and rehabilitation course. Fifty patients completed the study.

In-vitro anticancer and antimicrobial activities of PLGA/silver nanofiber composites prepared by electrospinning.

In the present work, a series of 0, 1 and 7 wt% silver nano-particles (Ag NPs) incorporated poly lactic-co-glycolic acid (PLGA) nano-fibers were synthesized by the electrospinning process. The PLGA/Ag nano-fibers sheets were characterized using SEM, TEM and DSC analyses. The three synthesized PLGA/silver nano-fiber composites were screened for anticancer activity against liver cancer cell line using MTT and LDH assays.

In vitro assessment of Function Graded (FG) artificial Hip joint stem in terms of bone/cement stresses: 3D Finite Element (FE) study.

Background: Stress shielding in the cemented hip prosthesis occurs due to the mismatching in the mechanical properties of metallic stem and bone. This mismatching in properties is considered as one of the main reasons for implant loosening. Therefore, a new stem material in orthopedic surgery is still required.

Human stromal (mesenchymal) stem cells from bone marrow, adipose tissue and skin exhibit differences in molecular phenotype and differentiation potential.

Human stromal (mesenchymal) stem cells (hMSCs) are multipotent stem cells with ability to differentiate into mesoderm-type cells e.g. osteoblasts and adipocytes and thus they are being introduced into clinical trials for tissue regeneration.

Osteomyelitis following Bacille Calmette-Guerin vaccination.

Secondary complications after Bacille Calmette-Guerin (BCG) vaccination are unusual. We describe 3 immunocompetent children who developed osteomyelitis after BCG vaccination. The course of the disease is not dramatic, but marked changes are frequently visible in plain radiograph and MRI.

The early detection and management of unstable concentric closed reduction of DDH with percutaneous K-wire fixation in infants 6 to 12 months of age.

Background: In some infants with developmental dysplasia of the hip, concentric closed reduction, although initially achievable, cannot be maintained even by casting because of a deficient posterior acetabular wall. Usually, these hips will redislocate in the cast and a rereduction will be necessary, often requiring an open reduction subsequently.

Methods: A 3-year retrospective review of 88 infants, (M/F; 14/74) 6 to 12 months of age with 124 dislocated hips, was conducted to assess the efficacy of percutaneous Kirschner wire fixation in achieving permanent hip stability.

Efficacy of aspiration and autogenous bone marrow injection in the treatment of simple bone cysts.

Twenty eight patients with simple bone cyst that were treated by aspiration and percutaneous autogenous bone marrow injection were reviewed to evaluate the treatment outcome. There were 18 boys and ten girls. Their mean age was 10.

Outcome after pelvic sarcoma resection reconstructed with saddle prosthesis.

Unlabelled: We retrospectively reviewed 27 patients who had saddle prosthetic reconstruction for pelvic sarcoma from 1991 to 2001 with a mean followup of 45 months. Functional outcome was assessed with Musculoskeletal Tumor Society Scores of 1987 and 1993 and the Toronto Extremity Salvage score. Survival, recurrences, and complications were recorded.

Iliosacral resection for primary bone tumors: is pelvic reconstruction necessary?

Unlabelled: Iliosacral resection for primary bone tumors creates a large unstable pelvic ring defect, the treatment of which remains controversial. We did this study to determine if skeletal reconstruction of such defects is necessary. Sixteen patients whose data were collected prospectively had iliosacral resection with a minimum followup of 12 months.

Effect of the oral contraceptive pill on ligamentous laxity.

Objective: Women are 4 to 8 times more likely to sustain a serious knee injury than their male counterparts. Previous studies have found that female sex steroids affect ligamentous tissue properties. The hypothesis is that there exists a difference in ligamentous laxity between oral contraceptive pill (OCP) users and nonusers.

Ganglion cyst and olecranon physis nonunion in a baseball pitcher: unique treatment after conservative therapy fails.

Although ganglion cysts and stress fractures occur at many joints, the presence of both disorders at the same joint is rare. In this unusual case, a 30-year-old professional pitcher had been treated conservatively for presumed olecranon bursitis in his right (throwing) arm, but, when therapy failed, he sought additional care. A thorough workup and subsequent surgery revealed a ganglion cyst and nonunion of a stress fracture of the olecranon physis.
