Allis’s maneuver: for Hip Dislocation

Gravity Method of Stimson Bigelow’s Maneuver: for Posterior Hip Dislocation Closed Reduction Discussion patient is placed in the supine position; knee is flexed to relax the hamstrings; assistant stabilizes the pelvis and applies a lateral traction force to the inside of the thigh; longitudinal traction is applied in line w/ axis of femur, and the hip is … Read more

Allograft Bone Patellar Bone Reconstruction

– Discussion:     – general discussion of allograft tissue:     – as pointed out by Harner et al. (1996), subjective knee scores were slightly better for knees having ACL – bone patellar bone allograft (as compared to BPB autograft patients)            – objective ratings included normal (or nearly normal) … Read more

Allografts

– see bone graft menu – Discussion of Allografts:     – see autograft menu and bone healing:      – allografts are most indicated when bone grafting is required along with need for mechanical structural support;     – morselized bone graft:     – structural bone grafts:      – fresh allografts            – generally … Read more

Allopurinol Interactions and Toxicities

Hypersensitivity Decrease dose with renal insufficiency Interaction w/ Dicumarol (prolonged PT) Thiazide diruretics (increased allopurinol toxicity) Ampicillin/amoxicillin (skin rashes) Chlorpropamide (increased hypoglycemia) Cyclophosphamide and other cytotoxic agents (bone marrow suppression); the allopurinol hypersensitivity syndrome is characterized by fever, eosinophilia, leukocytosis, impaired renal function, hepatocellular injury and rash; these reactions are severe and may be fatal; … Read more

Allopurinol/Zyloprim/Lopurin

– Discussion: – for established gout (Not acute Gout), hyperuricemia of malignancy (or increased cell turnover); – is useful for established gout with urolithiasis (both for uric acid stones and calcium oxalate stones); – adult: Initially 100mg PO qd; – increase by 100mg at weekly intervals until serum uric acid of < 6mg/dl is attained … Read more

Alendronate / Fosamax

– Discussion: (see bisphosphonates)     – type of aminobisphosphonate (a synthetic analogs of pyrophosphate) which acts as an inhibitor of osteoclast-mediated bone resorption;     – due to substantial reduction in bone resorption, bone formation exceeds bone resorption at these remodeling sites, which leads to                progressive gains in bone mass;     – this … Read more
