Adductor Brevis

Origin: outer surface of inferior ramus of pubis; Insertion: on a line extending from lesser trochaner to linea aspera and proximal 1/4 of linea aspera; Action: adduction of the femur at the hip; lateral rotation as it adducts the thigh.  some assistance to femur flexion at the hip; Nerve Supply:  Obturator,  L2, L3, L4;  (See Innervation) Synergists: Gracilis, Pectineus

Actinomyces bovis

– enters through an abrasion on the skin, associatted w/ cattle, swine ect; – a granuloma occurs that resembles TB, and a sinus formation results; – the infection may be resent to treatment; – treatment includes penicillin and potassium iodide; – chronic suppurative disease that is notorious for its assoc w/ draining sinuses.; – exudate … Read more

Active Abduction View

– Discussion:      – may allow use of plain x-rays for dectection of pts with complete Rotator cuff tears;      – this view showed narrowing of acromiohumeral space to 2 mm or less;      – view is obtained by having pt actively abduct shoulder to 90 deg and repeating an anteroposterior radiograph

Acumed Bone Graft System

Autogenous bone graft remains the most effective treatment for fracture non unions, pseudoarthroses and for optimizing the success rate of arthrodesis. It is safer and more effective than artificial hydroxyapatite materials or allograft. The Acumed bone graft harvesting instruments facilitates safe, rapid harvest of morsellized autogenous graft through a small skin incision which minimizes the … Read more

Acute Ligament Repair for SLD

by William Mallon MD  – Skin Incision:     – Identification of Radial Nerve:   – Identification of 3-4 Interval:   – Longitudinal Arthrotomy:   – arthrotomy performed just distal to Lister’s tubercle over scapholunate interval;  – this should provide clear exposure of scaphoid and lunate;  – alternatively, a distally based capsular flap can be … Read more

Acute on Chronic Slip

– Clinical Presentation:  – pts recounts h/o aching in hip, thigh, or knee (from chronic slip) along w/ h/o sudden severe pain (from concomitant acute slip); – Treatment:  – pin placement:  – reduction may be obtain by gentle skeletal traction in flexion & internal rotation; – forceful manipulation must be avoided.

ACL Graft Fixation

 – Discussion:     – see Arthrex, Mitek, Linvatec, Smith-Nephew     – in choosing a fixation technqiue consider the need for the following:              – circumferential (360 deg) healing of graft against tunnel wall (interference screws do not permit this);              – bioabsorbable material … Read more
