Knee
Down’s Syndrome: Orthopaedic Considerations
– Associated Conditions: – ligament laxity – hypotonia – mental impairment – heart disease (50%) – endocrine disorders (hypothyroidism and diabetes) – premature aging – spinal abnormalities: – atlantoaxial rotatory subluxation in Down’s syndrome – evaluated … Read more
Double Bundle ACL
– many techniques described with one or two tibial and one or two femoral tunnels – much biomechanical data confirms that both bundles are necessary to restore – ACL function – main findings are that PL bundle contributes to rotational stability closer to full extension – Distribution of in situ forces in the anterior … Read more
DMD: Contractures of the Lower Extremities
– Discussion: – contractures and progressive weakness of lower extremities render walking increasingly difficult for patients who have DMD; – average patient is unable to walk effectively by the time that he is ten years old, in the absence of treatment; – age at which walking ceases, however, is … Read more
DMD: Equinus Contractures
Discussion progressive paralytic equinovarus is an important reason for gait deterioration in pts w/ DMD; equinus contracture compensates for incr quadriceps weakness & allows knees to lock by enabling wt line to pass in front of knee joint; feet become progressively fixed in equinus & then equinovarus position; posterior tibial muscle retains good f(x) despite … Read more
Distal Realignment for Patellar Subluxation
– See: – Q angle – Malalignment of Patella – Discussion: – distal realignment procedures are chiefly indicated in pts w/ patellar subluxation, absence of hyper-laxity, and increased Q angle; – as pointed out by Fulkerson, et al (1990), less than 2% of patients w/ patellofemoral pain will require tibial tubercle transfer; – as noted … Read more
Distal Femoral Physeal Fractures
– See: – Growth Deformities of Limbs – Growth Plate Arrest – Discussion: – anatomy of distal femoral physis: – account for approx 5% of all physeal frx; – displacement in sagittal plane is assoc w/ N/V injury in popliteal fossa and instability on closed reduction; – … Read more
Distal Femoral Physeal Frxs: X-ray Evaluation
– Radiographic Evaluation: – SH Type I: – physeal frx about knee are more common than lig. injuries in children; – stress-views & circumferential physeal tenderness help to make the diagnosis; – SH Type II: … Read more
Distal Femoral Shaft Fractures
– See: – Femoral and Tibial Traction Pins – Supracondylar Femoral Fractures – Discussion: – failure of the nail to fill the canal of either the proximal or distal fragment, may lead to postoperative instability; – distal fractures within 10 cm of the joint line often can be treated successfully with standard IM nailing; – Traction Pins: … Read more
Distal Femoral Osteotomy
– Discussion: – degenerative valgus deformity of knee is less common than varus deformity; – genu valgum is more common in pts w/ history of trauma, RA, renal osteodystrophy, rickets, or infantile poliomyelitis; – Treatment Options: – goal of is to correct the angle between anatomic … Read more
