Department of Surgery Docs

Abstract

PURPOSE:

To assess the lower-limb alignment and posterior tibial slope in Pakistanis.

METHODS:

40 male and 19 female healthy Pakistanis aged 20 to 45 years were recruited. A full weight-bearing anteroposterior radiograph of the entire lower limb of each subject was obtained. The axial alignment was measured based on the centres of the femoral head, knee, and ankle. The tibiofemoral (TF) angle, knee joint line obliquity angle (angle J), and posterior tibial slope were determined.

RESULTS:

The mean TF angle was more varus in men than women (178.4 degrees vs. 180.0 degrees, p<0.001). The mean angle J was more medially inclined in men than women (93.4 degrees vs. 91.4 degrees, p=0.007). The mean medial tibial slope was greater in women than men (16.0 degrees vs. 12.5 degrees, p<0.001). The posterior tibial slope was greater in women than men (14.1 degrees vs. 12.5 degrees, p=0.02), and was greater than the 5 degrees to 10 degrees commonly reported.

CONCLUSIONS:

Knee alignment and geometry vary …

Acellular Dermal Regeneration Template For Soft Tissue Reconstruction Of The Digits., John S. Taras, Anthony Sapienza, Josh B. Roach, John P. Taras

Department of Orthopaedic Surgery Faculty Papers

PURPOSE: Trauma to the digits often leaves soft tissue defects with exposed bone, joint, and/or tendon that require soft tissue replacement. The objective of this study was to evaluate the effectiveness of acellular dermal regeneration template combined with full-thickness skin grafting for soft tissue reconstruction in digital injuries with soft tissue defects.

METHODS: Acellular dermal regeneration template was used to reconstruct digital injuries with exposed bone, joint, tendon, and/or hardware not amenable to treatment with healing by secondary intention, rotation flaps, or primary skin grafts. Acellular dermal regeneration template was applied to 21 digits in 17 patients. Nineteen digits had …

The Power Of Empowerment: An Icf-Based Model To Improve Self-Efficacy And Upper Extremity Function Of Survivors Of Breast Cancer, Mary Insana Fisher, Dana Howell

Physical Therapy Faculty Publications

Breast cancer is one of the most frequently diagnosed cancers among women. Breast cancer treatments often negatively impact the function of the arm, and quality of life and upper extremity function does not always return to a prediagnosis level. Survivors of breast cancer may also experience feelings of diminished self-efficacy related to functional deficits resulting from their physical limitations. The International Classification of Functioning (ICF) provides a framework for rehabilitation practitioners to address physical and psychological impairments, activity limitations, and participation restrictions. Patient outcomes may be improved by fostering self-efficacy through empowerment. This paper explores how the ICF model and …

Mast Cells And Hypoxia Drive Tissue Metaplasia And Heterotopic Ossification In Idiopathic Arthrofibrosis After Total Knee Arthroplasty., Theresa A Freeman, Javad Parvizi, Craig J Dela Valle, Marla J Steinbeck

Department of Orthopaedic Surgery Faculty Papers

ABSTRACT: BACKGROUND: Idiopathic arthrofibrosis occurs in 3-4% of patients who undergo total knee arthroplasty (TKA). However, little is known about the cellular or molecular changes involved in the onset or progression of this condition. To classify the histomorphologic changes and evaluate potential contributing factors, periarticular tissues from the knees of patients with arthrofibrosis were analyzed for fibroblast and mast cell proliferation, heterotopic ossification, cellular apoptosis, hypoxia and oxidative stress. RESULTS: The arthrofibrotic tissue was composed of dense fibroblastic regions, with limited vascularity along the outer edges. Within the fibrotic regions, elevated numbers of chymase/fibroblast growth factor (FGF)-expressing mast cells were …

Evaluation Of Lumbosacral Orthosis In Flexion And Extension Movements Of Lumbar Spine., Norazian Abd Razak

Student Works (2010-2019)

Lumbosacral orthosis (LSO) is a type of spinal orthosis that has been recommended for abdominal support, pain management, and motion or positional control. By implemented radiographic technique, objectives of this study was to evaluate the changes of lumbar lordosis in flexion and extension of trunk movements with and without wearing the LSO measured by Cobb, Centroid, and Posterior Tangent techniques and to correlate the value of lordotic angles in particular posture. Ten healthy male subjects without any history of low back pain participated and a semi-rigid LSO was utilized. Antero-posterior and lateral radiographs of spine images during neutral, flexion, and …
