If you want yourself to be dominated in the medical world then sqadia.com lets you achieve your goals with hundreds of medical lectures. This sqadia.com medical video lecture gives you an in-depth understanding of bone orthopaedic surgery. At first osteotomy is discussed. Internal and external methods of bone fixation are illuminated. Different kinds of bone grafts and substitutes are also conversed about. Distraction osteogenesis is the last subject of discussion in this section.
To inﬂuence joint function, osteotomy is used to correct deformity. Centre of the most proximal joint is connected to centre of most distal joint by an imaginary line known as limb axes or mechanical axis of limb. Alongside, information about reference angles is given. Moreover, presence of translation and angulation is highlighted. Rules and complications of osteotomy are discussed later on.
Bone fixation is a process in which two or more segments of bone are stabilized. It can be done via internal or external fixation methods. Internal Fixation by lag screw compress two fragments via lag principle. Alternative to lag screw ﬁxation is the cannulated variable pitch screws. External fixation can be done through static external fixators. Dynamic external fixation is also used for Proximal interphalangeal joint and Elbow joint.
Bone Grafts and Substitutes
In autografts, bone is transferred from one site to another in the same individual. Allografts consist of bone transferred from one individual to another of the same species. Some other forms of bone grafts are cancellous autografts, and vascularized grafts. Orthopaedic surgeon at sqadia.com also talks about bone marrow aspirates. Calcium-based synthetic substitutes fill metaphyseal defects.
Initially, Dr. Hammad Haider talks about distraction osteogenesis and limb reconstruction. Then information about callotasis is delivered. This is followed by chondrodiatasis which increases bone lengthening. Bone transport is used for filling segmental defects in bone. Then bifocal compression-distraction comes under consideration. To conclude, orthopaedic surgeon shed light on how to correct bone deformities and joint contractures.
