Data Trace Editor – Discussion: – indicated for increased exposure requirements or unacceptable laxity of the abductors; – Technique: – release the origin of the vastus lateralis from vastus tubercle; – osteotomy is performed 1 cm below vastus tubercle
(see also: Blair Fusion; Charcot Marie Tooth ; Equinovalgus; Grice Arthrodesis; Kocher approach; Ollier incision; Subtalar Fusion) Discussion results in fusion of subtalar, calcaneocuboid, and talonavicular joints; most effective procedure for fixed hindfoot and forefoot deformities; triple arthrodesis tend to have a high (50%) failure rate in children under 10 years of age; triple arthrodesis … Read more
– See: Triple Arthrodesis: Discussion: – Discussion: – reserved for the most intractable problems and can only be done close to or at the time of skeletal maturity; – when osseous correction of the midfoot is needed, we prefer to maintain the talonavicular, calcaneocuboid, and talocalcaneal joints by using calcaneal and midfoot osteotomies supplemented with … Read more
– See: – Blood Supply to the Wrist – Triquetrolunate Dissociation – Discussion: – triquetrium is the 3rd most commonly fractured carpal bone; – ular side of the wrist is supported by TFC, which articulates w/ both lunate and the triquetrum; … Read more
– Positioning of the Forefoot: – if there is a tendency to err in one plane, err to place medial forefoot more plantarward than the lateral aspect of the foot; – forefoot should be in about 3-5 deg of valgus when ankle is in a neutral position; – this … Read more
– PreOp Planning: – knee deformities should be corrected prior to any forefoot fusions; – stability of talus in mortise is necessary for successful arthrodesis; – determine if flexibility of forefoot and hindfoot; – if foot can be reduced to a satisfactory position then an in situ type of arthrodesis may be considered; – if … Read more
– Discussion: – trochanteric non union is thought to occur in 2-15% of cases (following trochanteric osteotomy); – most trachanters that heal by osseous union do so within 3 months; – between 3 and 6 months, they are considered delayed union; – beyond … Read more
– See: After-Loading Agents: – Discussion: – for production of controlled hypotension during surgery; – treatment of HTN Crises, HTN, pulmonary hypertension; – note additive effect w/ other Antihypertensive agents; – Adults: 0.5-1mg/min IV infusion titrated to effect
– for pruritis associatted with allergic and nonallergic conditions; – acts as antihistamine of phenothiazine type; – Adult: 2.5mg PO qid PRN or 5mg PO q12hr sustained realease; – Note that extrapyrimidal effects may occur in the elderly
– See: Technetium 99m – Discussion: – initial dynamic images are aquired over the area of concern and then followed immediately afterwards by static images obtained over longer periods of time; – First Phase: – demonstrates perfusion to a lesion; – first phase, the nuclear angiogram or flow phase, … Read more
