– Discussion: – indicated for comminuted radial head frx which occur w/ concomitant MCL injury, dislocation, or RU joint disruption (Essex Lopresti Fracture); – will serve as spacer & will prevents proximal migration of radius; – w/ RU joint disruption, radial head spacer alone does not restore satisfactory axial stability w/o pinning the distal radioulnar … Read more
– Discussion: – most commonly found in medial aspect of lateral meniscus; – radial tears of the posterior aspect of the lateral meniscus may be found in association with an anterior cruciate disruption; – may be associated w/ meniscal cysts which do not have to be removed … Read more
– See: – Rheumatoid Arthritis – Extensor Tendon Lacerations – Mallet Finger – Rheumatoid Wrist – Teno-synovectomy – Discussion: – ulnar side of wrist is most common site of extensor tendon ruptures; – pathophysiology: (caput ulnae syndrome) – this most often due to attritional changes due to caput ulnae syndrome; – volar subluxation of the … Read more
– Anatomy: – flexor sheath of thumb usually extends from distal phalanx to a point 2-4 cm proximal to volar wrist crease; – proximal half of tendon sheath is commonly referred to as the radial bursa; – occasionally proximal half of FPL sheath is separate from distal sheath, making them … Read more
– See: – Classification: – Stage I: – synovitis; – treated w/ splinting; – Stage II: – joint space narrowing with bone erosions; – treated w/ splinting and surgical synovectomy; – Stage III: … Read more
– See: Technique of Free Tendon Grafting – Discussion: – prosthetic graft serves as temporary spacer around which a pseudotendon sheath forms, & provides a healthy bed in which to place tendon autograft; – pulleys can be reconstructed at time of insertion of prosthesis – … Read more
– See: Knee Joint Menu – Patient Positioning and Preparation: – positioning: – opposite limb is well padded to prevent potential pressure problems; – operative thigh is placed against an arthroscopy post or is placed in a circular thigh immobilizer; … Read more
– Evaluate Proximal Stem: – decide whether trochanteric osteotomy is required; – it is essential to avoid a proximal femoral frx while extracting the stem; – direct extraction of a femoral stem can be blocked by excessive cement or proximal bony overgrowth medial to the greater trochanter; … Read more
– Discussion: – is apparent when with stress testing lateral tibial plateau rotates posteriorly in relation to the femur with lateral opening of joint; – atraumatic type: – presents as chronic laxity, often with a varus knee deformity; – this ligamentous laxity often … Read more
– Discussion: – arises from disruption of the lateral collateral and annular ligaments; – associated conditions: elbow dislocation, radial head excision, coronoid fracture; – diff dx: lateral epicondylitis – LCL anatomy: – lateral collateral ligament consists of a ligamentous expansion proceding down from lateral … Read more
