Anterolateral Approach to Hip Joint: (Watson Jones)
– See: Smith Peterson Approach – Discussion: – major problems with the Watson Jones technique are dealing w/ gluteus medius & minimus, which lie over anteior capsule and must be damaged or cut to obtain adequate exposure; – original Charnely technique used anterolateral approach w/ pt supine, osteotomy of greater troch, … Read more
Anterior Approach to the Hip (Smith Petersen)
– See: Watson Jones Approach – Discussion: – Smith Petersen improved & revived the anterior iliofemoral approach; – entire ilium and hip joint can be reached thru iliac part of incision; – w/ this approach there is a need for extensive detachment of tendinous insertions & retraction of muscle, w/ potential damage to femoral artery and … Read more
Anterior Approach to the Radial Shaft: (Henry)
– See: – Anterolateral Approach to Forearm – Forearm Flexors – Plating Techniques – Radial Shaft Fractures: Discussion – Discussion: – anterior approach of Henry utilizes interval between brachioradialis (radial nerve) & pronator teres (or FCR distally, which are innervated by the median nerve); – … Read more
Anterior Arthrodesis of Cervical Spine
– See: Anterior Approach to Cervical Spine: – Discussion: – Smith Robinson disectomy & block fusion is preferred over Cloward dowel for involvement of one or two interspaces; – for multi-level spondylosis & myelopathy, w/ more extensive anterior decompression involving excision of osteophytes & multiple vertebrectomies, a strut graft fusion … Read more
Ankle Arthrodesis
(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
Ankle Arthrodesis – Discussion
– 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
Anatomy of the CMC Joint
(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
Anatomy of Carpal Tunnel
– Discussion: – transverse carpal ligament, is a heavy band of fibers which runs between hamate & pisiform medially to scaphoid and trapezium laterally, and forms fibrous sheath which contains carpal tunnel anteriorly within fibro-osseous tunnel; – posteriorly, tunnel is bordered by carpal bones, and transports median … Read more
