Hemivertebrae
Which nerve supplies the peroneus brevis
Superficial peroneal nerve
ACL attaches to the non-articulated aspects of the tibia and the posterior aspect of the..
Medial surface of the lateral femoral condyle
Presentation of combined median ulnar nerve lesion
Wrist is slightly hyperextended and inclined to radial side
Ape hand- thumb in the plane of the hand and slightly abducted.
MCPj- hyperextended
IP-slightly flexed
Patient can not abduct or adduction finger
Sensory symptoms are lost in hand
Mot appropriate orthosis for a patient with a median and ulnar nerve laceration at the wrist
WHO w/ spring wire wrist flexion assist
Brachioradialis primary and secondary function
1°- flex elbow
2°- supination
What nerve innervates the gastrocnemius and soleus
Tibial nerve
Which of the following muscles BEST substitutes for a non-functional tibialis anterior A. Tibialis posterior B. Extensor hallucis longus C. Extensor digitorum brevis D. Peroneus longus
B. Extensor hallucis longus
Inflammation anterior to the flexor retinaculum is called
Carpal tunnel
The greatest advantage that a dorsal style WHO has over a volar style WHO is that it
Allow tactile sensation
The extensor carpi ulnaris works synergistically with the _____ to provide wrist extension
Extension digitorum
A patient presents with no volitional strength to the thumb. What component will you recommend
Thumb post
Which of the following deformity in the fingers is most similar to a hammer toe
Boutonniere
The volar surface of the forearm contains the ____muscles, which as a group originate at the ____humeral epicondyle
Wrist flexor, medial
Most common etiology of a stroke is
Embolic
A dynamic IP extension assist with an MP extension stop should be used if a patient
Has lumbrical weakness and has hyperextended MPs
A 68year old female presents with RA. What deformity is most likely occurring at her MPs
Volar subluxation and ulnar deviation
The correct distal trimline of the thumb adduction stop (C-bar) bar is
Proximal to 1st MCP
MOST likely use a balanced forearm orthosis?
Quadriplegic with fair shoulder power
Swan neck deformity, the pip joint is
Hyperextended and the DIP is flex
C6 quad, which muscles will the patient use to manipulate a WHOwrist driven for prehension
Extensor carpi radialis longus and brevis
The 1st CMC is what type of joint
Saddle joint
Most important motor acquisition of the c5 quad is
Shoulder/ elbow flexion
A boutonnière deformity consists of PIP
Flexion and DIP hyperextension
C1- atlas characteristics
Atypical No spinous process No body Can move independent of other vertebrae Yes-yes motion Atlanto-occipital joint Atlanta-axial joint
C2 axis characteristics
Atypical Spinous process Body Odontoid process Greatest transverse motion No no motion
3 stabilities of spine
Nerve stability
Mechanical- ligament (passive)
Musculoskeletal- muscle
C3-7 characteristics
Bifid spinous process Typical C4-5 and C5-6 most mobile segments w/i cervical spine C7 most prominent spinal process Mobility allowed from facet orientation
Jefferson fx C1
Burst fx 3-4 fx lines in atlas MVA common Axial loading of head HALO
Odontoid fx C2
Type I- odontoid tip only (moderate)
Type II-odontoid fx at base (sever)- fusion, Halo
Type III-fx in to body of axis still have ligament stability- halo or ridge CO
Compression fx failure of
Anterior column
Burst fx- failure
Anterior and mid column
Seatbelt fx failure
Posterior and middle column
Dislocation fx failure
All 3 column fail
Lower cervical spine trauma- rotation w/ dislocation
Unilateral facet dislocation- halo
Lower cervical spine trauma- flexion distraction
Bilateral facet dislocation-true spondylolisthesis- very unstable: surgery
Lower cervical spine trauma- extension
Fx of Pars interarticular…ox?
