A system for measuring the stump-socket interface pressure was designed and built using a strain gauged type load cell. The system was utilized to study the pressure distribution in the quadrilateral and ischial containment type sockets. Two volunteer trans-femoral amputees fitted with both types of socket participated in the experiments. Pressures were measured while the subjects were standing...

A computer-aided socket design procedure (CASD) has been developed whereby an above-knee socket shape can be created based on anthropometric measurements taken from an amputee. The anthroometric measurements are used to select a subset of three reference shapes from a Reference Shape Library stored in the computer in the form of three-dimensional numerical data. Transformation procedures then s...

A bucket-type transpelvic socket was fabricated for a man with paraplegia from spinal cord injury, who underwent right partial pelvic amputation and left hip disarticulation. His main problem was inability to sit due to asymmetrical pelvic shape. We prescribed a transpelvic prosthetic socket to enable him to sit again. The socket consisted of a dual structure: a hard frame and soft liner. The m...

This study compared the pressure distribution at the residual limb and socket interface in amputees wearing a pressure cast (PCast) socket system with amputees wearing the patellar-tendon-bearing (PTB) socket. The PCast system requires the subject to place his or her residual limb in a pressure chamber. Pressure is applied to the residual limb while the subject adopts a normal standing position...

A prosthetist makes a conventional socket by wrapping plaster bandage around the residual limb and using the resulting shell to create a positive model. After he or she modifies the plaster, it is used to create a laminated socket. Such sockets are almost perfect cylinders that encapsulate the limb. The bone is centered in soft, compressible tissue that must move aside before the bone can push ...

Introduction and purpose:
 Alveolar osteitis, also known as dry socket is a common complication after tooth extraction, especially third molar extraction. Taking into consideration only extractions, the prevalence of reaches even 45%. The aim this literature review was to describe current knowledge about etiology, risk factors, treatment, prevention socket.
 State knowledge:
 sym...

Iodoform is also known as triiodomethane a yellow crystalline solid belongs to the family of organic halogen compounds used as an antiseptic component of certain medications. It was first prepared in 1822 by electrolysis of aqueous solutions of acetone, inorganic iodides and sodium carbonates. It s antiseptic action discovered in 1880, which made it an important medicinal. It has no irritant ac...

This work, supported by the Media Lab Consortium, evaluates the design of a Variable Impedance Prosthetic (VIPr) socket for a transtibial amputee using computer-aided design and manufacturing (CAD/CAM). Compliant features are seamlessly integrated into a 3D printed socket to achieve lower interface peak pressures over bony protuberances by using anthropomorphic data acquired through surface sca...
