GMNR Legacy Series: Intro to Prosthetics

Gautam Malhotra MD presents an overview and introduction to amputee rehabilitation and prosthetics. It starts with a general discussion, then amputee related issues, then a basic approach to learning about prosthetic componentry. "GMNR" is a tongue-in-cheek play on words (PM&R) which stands for Gautam Malhotra's Notes and Reviews. The GMNR Legacy Series includes 20 years' of educational content created by Gautam Malhotra MD for Physical Medicine and Rehabilitation trainees (both resident physicians and medical students). These slides can be used as references and study materials. 0:00 Introduction 1:36 History, trajectory, and Causes of Amputation 3:00 Prognosis 3:27 Role of the Physiatrist 4:00 Pre-Amputation 5:47 Types of Amputation, Myoplasty and Myodesis 7:24 Post-Op Wound Care and Edema Control 12:15 Functional Rehabilitation: Preprosthetic trainin, Pain Management, and Psychological adjustment 25:30 Skin Problems in the Amputee 32:05 Immediate Post-Op Prosthesis (IPOP) 33:11 Lower Limb Amputation levels 34:22 Partial Foot Amputations: toe and ray 34:55 Partial Foot Amputations: TMA, Chopart and Lisfranc 37:42 Transtibial Below Knee BKA Amputation 38:59 Transfemoral Above Knee AKA Amputation 39:44 Hip disarticulation and Hemipelvectomy 40:38 Hemicorporectomy 41:16 Energy Cost of amputation 43:36 K Level Modifiers Describing Potential Functional Levels 46:10 Residual Limb vs Stump 47:20 Introduction to Componentry 47:48 Prosthesis vs Orthosis 48:17 Prosthosis and Componentry for partial foot 49:32 Prosthesis, Prosthetic, and Prosthetist 50:03 Categories of Components 50:59 Endoskeletal vs. Exoskeletal Construction 52:47 Sockets: Traditional fabrication 54:14 Sockets: CAD/CAM fabrication 55:35 Sockets: flexible vs rigid and soft vs. hard 58:13 Sockets: Liners 59:09 Sockets: BK Shapes Plug fit vs Total Contact 1:00:43 Sockets: AK Shapes Quadrilateral vs Ischial Containment 1:01:53 Sockets: Flexible inner socket and rigid outer frame 1:02:34 Suspensions 1:02:45 Suspensions: AK suction 1:05:34 Suspensions: AK non-suction 1:05:15 Suspensions: BK Flexible vs Rigid 1:06:25 Foot/Ankle 1:08:38 Knees Mechanical Friction vs Fluid Friction and microprocessor 1:12:13 Syme prosthesis 1:13:11 Hip disarticulation and Hemipelvectomy prosthesis 1:13:46 Hemicorporectomy prosthesis 1:15:11 Van Ness Rotationplasty 1:16:16 Stubbies 1:16:14 Revisiting the Physiatrist's Role 1:19:02 Advanced topics in Sockets including the history, sub-ischial, MAS, and TSB vs PTB
