Anterior Cruciate Ligament

– Extra-articular Reconstruction: – these type of procedures are now no longer used as the primary reconstructive method for ACL tears; – some authors feel that the extra-articular reconstruction may have a role in augmenting the intra-articular reconstruction; – references: – Biomechanics of intra-articular and extra-articular reconstruction of the anterior cruciate ligament. – The effect … 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 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

Anterior Column of the Acetabulum

– See: Classification and Column Theory – Discussion:     – anterior column extends from symphysis pubis & obturator foramen thru               acetabulum to ASIS and up through iliac crest;     – anterior column is less frequently fractured than posterior column due to frequency               of posteriorly directed forces;     – frxs of the anterior … Read more

Anterior Column: the anterior half of the vertebral body

(See: Ligamentous Instability:) Discussion antatomic structures in the anterior column that resist compression forces are the vertebral body centrum and intervertebral disc; structures that counter act tensile forces in anterior motion segment are anterior longitudinal ligament and the annulus fibrosis; stable injuries to anterior column include compression frx of < 25% loss of vertebral body ht. … Read more
