Polar membrane glycerolipids occur in a mixture of molecular species defined by a polar head group and characteristic acyl groups esterified to a glycerol backbone. A molecular species of phosphatidylglycerol specific to chloroplasts of plants carries a Delta(3-trans) hexadecenoic acid in the sn-2 position of its core glyceryl moiety. The fad4-1 mutant of… (More)
Three patients with calcaneal fractures developed clawing of the lesser toes as a late sequela. Believing that this complication may be the result of contractures from an occult compartment syndrome of the foot, an investigation of the anatomical compartments of the foot was performed. The various compartments of 17 unembalmed adult lower limb specimens… (More)
Posterior antiglide plates recently have been introduced as a method of fixation for the short oblique fracture (Type B, as defined by the AO Group) of the distal part of the fibula. This method has several advantages over the more commonly used lateral plate for the fixation of this type of fracture, including dissection of a smaller area and less… (More)
CONTEXT Medial impingement syndrome of the ankle is common in the athletic population. A marginal osteophyte on the leading edge of the medial talar facet and a corresponding "kissing" osteophyte on the tibia, in front of the medial malleolus, may abut and cause pain and limited dorsiflexion. BACKGROUND Palpation of the talar osteophyte and standard… (More)
External fixation is a useful tool for treating severe traumatic injuries to the foot and ankle. External fixation, however, does have associated complications, such as inadequate fixation and pin tract infections. Temporary bridge plating of the medial, lateral, or both columns is a useful alternative to external fixation for treating multilevel foot… (More)
A case demonstrating a mechanical cause of posterior tibial tendon degeneration is reported. The possible etiologies for degeneration of the posterior tibial tendon are discussed.
