A Prosthesis With Sensory Capability – Todd Kuiken On Future Robotic Arm

Prosthesis development has taken big strides recently. Research has shown that targeted reinnervation enhance the capabilities of prosthetic arms  to allow the amputee to “feel” temperature, texture, etc.

Todd Kuiken is the doctor/engineer behind the concept.

Here is a video where he talks about future of the prosthetic arm

Solid Ankle Cushioned Heel (SACH) Foot

SACH is an acronym for “solid ankle, cushion heel,” and refers to a compressible heel wedge that provides “pseudo-plantar flexion” after heel strike. The rigid wooden keel provides midstance stability but little lateral movement. The SACH is inexpensive, light, durable, and available in various heel heights so people can wear different shoes.

The SACH foot was developed at the university of California at Berkeley in 1955 and was based on a Canadian prototype for Syme prosthesis.
In SACH prosthesis, ankle and foot are combined into one component consisting of rigid wooden keel with a compressible heel firmly attached to the shank of the leg so as to eliminate constant loosening and resultant torsion,

Rocker Bottom Shoe

A rrocker bottom shoe is a shoe which has a thicker-than-normal sole with rounded heel to ensure the wearer does not have flat footing along the proximal-distal axis of the foot. Other terms for this shoe are round bottom shoes, rounded sole shoes and toning shoes.

ROCKER BOTTOM SHOE

Rocker Bottom Shoe

Uses

  • To reduce the function or replace the lost function of a joint
  • To compensate for the lost range of motion

Rocker Bottom Shoes should be worn when advised by your doctor.

Thoracic Lumbar Sacral Orthosis

Thoracic Lumbar Sacral Orthosis or TLSO is a device that is used for stabilizing or supporting the thoracic, lumbar and sacral area. That covers the area between collar bone and pelvis.

Cervical Thoracic Lumbar Sacral Orthosis

Cervical Thoracic Lumbar Sacral Orthosis is a device that is used to stablize or support the spine from cervical to sacral area. The use can be in traumatic injuries of spine or to correct the curvature in scoliosis

The device is usually custom made after taking the measurements of the patient in whom it is to be applied.

What Is C Arm?

A C-arm is also called xray image intensifier and is a commonly used gadget in orthopedic surgeries. It is also used in many other procedures like gastroendoscopy, vascular surgery, neurosurgery etc.

There are two types of C-arms or fixed image intensifiers – fixed and mobile.

Xray image intensifier

It is an imaging device which uses X-rays and produces a live image feed which is displayed on a TV screen. The term image intensifier refers to a special component of the machine, which allows low intensity X-rays to be amplified, resulting in a smaller dose to the patient. [Read more...]

Cervical Collar And Lumbar Supports In Pain Management

Orthoses or a kind of splints applied to different parts of body to limit movements which can aggravate the existing pain.

Commonly used orthoses are cervical collars and lumbar supports. Following factors should be taken into account before the orthoses are prescribed.

  • Examination  suggests that supports or reduced mobility benefits the patient.
  • Patient must understand that it is a temporary measure.
  • If the supports aggravates the problem, it should be removed.

Sternal Occipital Mandibular Immobilization Brace

The sterno-occipital-mandibular immobilizer (SOMI) cervical orthosis is a rigid cervico thoracic orthosis  used for supporting the ervical spine . SOMI does not provide complete immobilization though. It is somewhere between a Philadelphia collar and a halo brace.

Structurally, it has a chest plate that goes up to the notch where the collarbones meet in the front and metal, aluminum, or plastic bars that curve over the shoulder.

Straps from the bars go over the shoulder and cross to the opposite side of the anterior plate to hold it in place.

A removable chin piece attaches to the chest plate with an optional headpiece that can be used when the chin piece is removed for eating.

The SOMI works well to control flexion of the upper cervical spine (C1-3). It does not control extension that well.

The SOMI is used to immobilize an unstable neck due to fracture or ligamentous injury or disruption.

The Minerva brace is a cervical and upper thoracic orthosis. It provides good orthotic control of the neck. There are many instances where Minerva brce can be used. For example severe whiplash injury or fracture of the vertebra or lower cervical fusion.

The Minerva orthosis has a rigid plastic posterior section that goes from the base of the skull down to the midtrunk. There is a solid chest piece in the front that is attached to the back along the sides with Velcro straps that can be adjusted.

Complications of Skin Traction

Skin traction is used where a smaller amount of force is required to correct the deformity. It may cause following complications

Skin Trauma

The skin is easily traumatized by this method and can cause various degrees of injury, from abrasion to partial-thickness skin loss.

If the elastic bandages are wrapped too tightly or unevenly, it may result in circulatory impairment and may lead to development of  pressure area. This is especially true for  bony and soft tissue prominences. [Read more...]
