Background: Percutaneous tendo-Achilles lengthening (PTAL) is a common procedure performed as an adjunct to other procedures that are used to treat a variety of foot and ankle disorders. Despite the widespread use of PTAL, the only literature to substantiate its efficacy comes from the treatment of forefoot ulceration in diabetics. The complications of the procedure include pain along the Achilles tendon, difficulty using stairs, weakness with toe-off, inadvertent complete tenotomy, and cosmetic appearance.

Study Design: Simulated discectomy was performed using 1) headlamp/loupes, 2) the operative microscope, or 3) neither; and bacterial shedding was assessed using air sampler/settle plate techniques.

Objectives: To determine the potential contribution of these 2 commonly used systems of magnification/illumination to postoperative infection by using a controlled, experimental setting to limit confounding factors.

Summary Of Background Data: Postoperative infections following surgery on the degenerative lumbar spine generally range from 0.

Approximately 3% of osseous tumors occur in the foot and ankle. Solitary bone cysts, chondroblastoma, intraosseous lipoma, osteoid osteoma, chondrosarcoma, and Ewing's sarcoma seem to have a predilection for the calcaneus. Biopsy is often a crucial step in management.

Objective: Granulomatous disorders may be associated with hypercalcemia. In sarcoidosis, the pathogenesis of hypercalcemia has been clarified, whereas in other granulomatous disorders, such as coccidioidomycosis, the mechanism is unclear. We present 13 patients with coccidioidomycosis and hypercalcemia to illustrate the clinical course and the mechanism of hypercalcemia.

The Higgs-boson production cross section at pp and pp colliders is calculated in QCD at next-to-next-to-leading order (NNLO). We find that the perturbative expansion of the production cross section is well behaved and that scale dependence is reduced relative to the NLO result. These findings give us confidence in the reliability of the prediction.
