– Discussion: – a common benign but locally aggressive lesion of unknown etiology; – occurs chiefly in men between 20-50 yrs (after epiphyseal closure); – tumor is expansile lytic lesion that involves the epiphysis & metaphysis; – tumor may enlarge to occupy most of epiphysis & adjacent metaphysis; … Read more
– Discussion: – bilateral angular deformity: common and is most often physiologic; – normal knee alignment progresses from 10-15 deg of varus at birth to maximal valgus angulation of 10-15 deg at age of 3-3.5 yrs; – neutral alignment: … Read more
– Discussion: – medial and lateral muscle bellies each carry long flaps of skin and fascia from the posterior calf and are most often used as myocutaneous flaps; these flaps are most useful for upper tibial defect reconstruction; – Contra-indications: – knee dislocation or … Read more
– Discussion: – bone provides and environment that significantly alters interaction between bacterial and host defenses in favor of the invader; – bone contains numerous microscopic channels, the walls of which are impermeable to such host defenses as the large molecules of immunoglobulins; – bacteria, once gaining a foothold in these … Read more
– See: – Achilles Tendon: – Gastrocnemius Flap: (see reconstructive surgery for the leg): – Anatomy: (see superficial posterior compartment); – origin: – lateral head: lateral condyle and posterior surface of femur; – medial head: medial condyle … Read more
– Discussion: – type of muscinous filled cyst whch is found adjacent to joint capsule or tendon sheath; – it consist of an outer fibrous coat and an inner synovial lining and contains a clear, colorless, gelatinous fluid; – ganglions usually occurs singly but may be multilocular; … Read more
– Technique: The fibula is approached through a lateral incision simultaneous to the hip approach. The surgeon stands on the posterior side. The incision is planned on a line directly over the fibula. The fibular bone cuts will be 15 cm apart with the distal cut at 10 cm proximal from the distal fibular tip. … Read more
– See: – Femoral Neck Frx – Discussion: – these injuries occur from high energy trauma and comprise 1-6% of all femoral shaft frx; – in up to 20% of cases, this injury is missed, which is often due to failure to take good quality femoral neck radiographs … Read more
– See: – Growth of Proximal Tibial Epiphysis – Avulsion of the Tibial Tubercle – Discussion: – injuries of prox tibial epiphysis are rare (3 % of lower extremity epiphyseal frx); – injury is uncommon because knee ligaments bypass proximal tibial epiphysis and instead insert more distally; … Read more
