Partial Knee Replacement

Partial Knee Replacement

Dr. Richard Cunningham, M.D. of Vail Summit Orthopaedics explains and performs Partial Knee Replacement. Unicompartmental knee replacement is an option for a small percentage of patients with osteoarthritis of the knee. Your doctor may recommend partial knee replacement if your arthritis is confined to a single part (compartment) of your knee. Your knee is divided into three major compartments: The medial compartment (the inside part of the knee), the lateral compartment (the outside part), and the patellofemoral compartment (the front of the knee between the kneecap and thighbone). In a unicompartmental knee replacement, only the damaged compartment is replaced with metal and plastic. The healthy cartilage and bone in the rest of the knee is left alone.

Pons, Simplified Sections Of Internal Structure

Pons, Simplified Sections Of Internal Structure

This video is part of a playlist of videos on the internal structure of the brain stem. In this video, internal structure at the following section levels is described: - Level of facial and abducent nucleus (lower pons) - Level of trigeminal nuclei (upper pons) - Level of open part of the medulla oblongata - Spinal cord For each fiber tract the location, function, origin and destination are summarized. Each nucleus is identified in terms of location, function and connections. Thus the session correlates anatomical structures seen in the pons with those of the medulla oblongata, midbrain and spinal cord. For this purpose, sections of the spinal cord, and medulla oblongata have also been added. After completion of this video session, it is expected that you will be able to develop a three dimensional picture of the gross anatomy of the medulla oblongata and its internal structure. Locate the positions of cranial nerve nuclei and the paths taken by the major ascending and descending nerve tracts. Assess the signs and symptoms presented by the patient and identify the exact location of a lesion affecting the brain stem. Correlate the signs and symptoms of pons astrocytoma with nuclei and nerve tracts involved by the tumor. Explain the difference in signs of upper and lower motor neuron lesions affecting the facial motor nucleus. Presented and edited by Dr. Akram Jaffar, Ph.D.

How to Read Knee MRI of Normal Knee

How to Read Knee MRI of Normal Knee

Colorado knee specialist Dr. Robert LaPrade discusses how to read knee MRI of normal knee. Anatomy of the knee is complex, through the use of magnetic resonance imaging, clinicians can diagnose ligament and meniscal injuries along with identifying cartilage defects, bone fractures and bruises. To begin, we use a coronal scan of a left knee. A coronal scan goes through the knee, front to back, with the dimensions being medial to lateral. To begin a coronal scan the patella is at the center. As the image moves deeper you can begin to see the quadriceps tendon and the patellar tendon below. We then move to the tibiofemoral joint. The medial and lateral meniscus come into view and the IT band on the side. As the image moves deeper you can begin to see the medial collateral ligament along the tibia and the anterior curciate ligament. On the lateral side of the knee the fibular collateral ligament. The ACL becomes more clear as you more deeper into the knee. The medial and lateral meniscal root attachments begin to appear. As we move more posterior aspect of the knee you can see the biceps femoris. Clinically, the coronal view is used to identify any medial or lateral meniscus injuries. The next image used is the sagittal views. The sagittal views look at the knee from front to back. You can clearly see the posterior and anterior horn of the lateral meniscus. The gray area around the bone is the articular cartilage. As we get more central in the joint, we can begin to see the patellar tendon. The ACL and PCL also come into view. As we move to the far medial aspect we will start to see the hamstring tendons. The last view is the axial view, which is like cutting through a log. As the image moves deeper into the knee you can see the outline of the menisci. We look for any ghost signs that may appear for radial tears. You can see the shiny white fibers of the posterior horn of the medial meniscus.

Medulla Oblongata, Simplified Sections Of Internal...

This video is part of a playlist of videos on the internal structure of the brain stem. Internal structure at the following section levels is described: - Level of inferior olivary nucleus (open medulla) - Level of medial lemniscal decussation (closed medulla) - Level of the decussation of pyramids (closed medulla) - Spinal cord For each fiber tract the location, function, origin and destination are summarized. Each nucleus is identified in terms of location, function and connections. Thus the session correlates anatomical structures seen in the medulla with those of the pons, midbrain and spinal cord. For this purpose a section of the spinal cord has also been added. After completion of this video session, it is expected that you will be able to develop a three dimensional picture of the gross anatomy of the medulla oblongata and its internal structure. Locate the positions of cranial nerve nuclei and the paths taken by the major ascending and descending nerve tracts, assess the signs and symptoms presented by the patient and identify the exact location of a lesion affecting the brain stem. Correlate the signs and symptoms of medial and lateral medullary (Wallenberg) syndromes with the nuclei and nerve tracts involved by the vascular lesions. Presented and edited by Dr. Akram Jaffar, Ph.D.

Mohan Desarda,
MD, PhD

Chief of Hernia Center, Poona Hospital & Research Center

Being focused on new endoscopic techniques in medicine (ESD - endoscopic submucosal dissection), I understand well the need to promote the latest innovation and discoveries. I recommend MEDtube video sharing website for doctors as tool to disseminate techniques and technologies improving doctors' skills and awareness globally. Good luck.

Takuji Gotoda,
MD, PhD

Tokyo Medical University Hospital

I was excited to discover MEDtube during my online research for video content in ortopedics. Such project was missing. Professional medical education requires more open and innovative approach. I will use the platform in my teaching activities and publish own content. I look forward to joint projects with MEDtube and promise my personal support in Hong Kong and continental China. Good luck!
