(see also: Sub-Talar Fusion, Tibial-Talar-Calcaneal Fusion Discussion and Outcomes: optimal position for fusion see gait and role of ankle joint in gait ref: Ankle arthrodesis. Long-term follow-up with gait analysis. Exam: perform an Allen test for the foot vasculature; note function of posterior tibial pulse while the dorsalis pedis pulse is occluded and vice versa; … Read more
– See: Sub-Talar Fusion Tibial-Talar-Calcaneal Fusion – Discussion: – for pts w/ well-aligned fusion, walking gait in appropriate shoe is almost normal; – expect 16% decrease in gait velocity and 3 % increase in oxygen consumption; – running … Read more
(See also: CMC arthritis) Discussion base of thumb metacarpal articulates w/ saddle shaped trapezium; saddle shaped articulation provides inherent stability; radial lateral ligament, which is covered by APL tendon, inserts into the thumb metacarpal; deep anterior oblique ligament (palmar beak ligament) originates on the tuberosity of the trapezium & insertes on ulnar and volar edge … Read more

Discussion AC joint is situated between the clavicle and acromion; acromion has two ossification centers which fuse at age 22 yrs; it permits motion in three planes: AP gliding of acromion during protraction & retraction of scapula; tilting of acromion during abduction & adduction of arm; rotation of the clavicle; rotation occurs during abduction & … Read more
(see also: Pseudoachondroplasia) Discussion autosomal dominant disorder; arises due to a point mutation for the gene encoding a fibroblast growth factor (Fibroblast growth factor receptor 3) over 80% of all persons with this disorder are born to parents who are not achondroplastic, & such parents rarely have second achondroplastic child; it is presumed in these … Read more
