a permanent finger deformity where the middle joint (PIP) is bent down, and the fingertip (DIP joint) is bent back, caused by a ruptured or damaged central slip of the extensor tendon from trauma or rheumatoid arthritis
boutonnière deformity
What is the function of the anterior pin in an ankle-foot orthosis (AFO) with a dual-channel ankle joint?
limits dorsiflexion
Name the most restrictive removable brace
minerva brace
What is the leading cause of UE amputation
trauma
Describe a K1 level ambulator
Limited to transfers or limited household ambulator
what type of orthosis is used for mallet finger
a stax splint
In patients with knee arthritis affecting mostly the medial compartment, which shoe insert will most effectively reduce the knee adduction moment?
Lateral heel wedge
Spinal orthotic prescription for adolescent idiopathic scoliosis should be considered once the Cobb angle reaches:
25 degrees
What is the most common location of an acquired pediatric traumatic amputation?
finger amputation
Estimate the increased energy expenditure in a bilateral transfemoral dysvascular amputee
300% (200x1.5)
describes a tenodesis splint
custom-made orthotic device that helps individuals with a spinal cord injury (specifically a C6 level or higher) to achieve a functional pinch grip
a swedish knee cage is used to
manage genu recurvatum
describe the 3 column model for spinal stability
divides the spine into an anterior column, a middle column, and a posterior column to assess stability after injury. If the middle column or 2 out of 3 columns are injured it is considered UNSTABLE
What is the most common congenital UE amputation?
What is the major advantage of a syme's amputation
allows for weight bearing on the distal residual limb
a gutter splint is used to help address
ulnar neuropathy
orthosis used to manage ACL injuries
Lenox hill derotation orthosis
What is the MOST important biomechanical factor for decreasing the vertical loading of the lumbar spine using a TLSO or LSO?
Reinforcing core/ abdominal musculature / elevate intra-abdominal pressure
Describe myoplasty versus myodesis
Myoplasty involves suturing transected muscles together, often to opposing muscle groups, to create a stable muscle mass for the residual limb. In contrast, myodesis secures the cut muscle directly to the bone of the residual limb, usually through pre-drilled holes. Myoplasty is preferred when vasculature is poor.
The primary advantage of an ischial containment socket over a quadrilateral socket in a transfemoral amputee is:
Promotion of femoral adduction by distributing the pressure through the socket along the shaft of the femur
what is a flail arm splint used for
brachial plexus injury
unsupported standing is possible with a
scott craig long leg brace (KAFO)
Name 1 pro and 1 con of a soft cervical collar
Pros: provides kinesthetic reminders to limit motions, retains body heat which may resude muscle spasms
Cons: muscle atrophy, psychological dependency
At what developmental stage should a child with congenital transverse radial limb deficiency be fitted for an initial prosthesis?
when they are able to sit independently (6 months)
what two things will result in an increased knee flexion moment during stance phase of a transtibial amputee
placing the socket more anteriorly
placing the foot more posteriorly
