The tensor fascia lata musculocutaneous flap.

The tensor fascia lata (TFL) muscle, together with the overlying skin of the anterolateral thigh, makes a reliable musculocutaneous unit. It can be lengthened safely by taking the fascia lata and the skin of the anterolateral mid and lower thigh to within 8 cm of the knee. The skin of the longer flap is supplied by large perforating musculocutaneous arteries, the terminal branches of the vascular pedicle of the muscle. The shorter flap can easily be transposed over the trochanteric area, while the larger flap will cover not only the trochanter but also the ischial and sacral areas. The flap serves equally well as a transposition, island, or free flap. The anatomical and vascular basis of the flap is presented, together with its application in 21 patients. Possible further applications of the flap, including anterior rotation, are discussed.

The tensor fascia lata myocutaneous free flap.

The tensor fascia lata muscle and its overlying skin provide a reliable myocutaneous unit containing a large amount of soft tissue for a free flap transfer. Its anatomy is outlined, and the operative technique for transfer is detailed in a case of chronic stasis ulcer of the lower leg.

The transverse lumbosacral back flap.

The transverse lumbosacral back flap is presented as a good one to use for coverage of sacral defects. Its reliability appears to be due to an axial pattern of its proximal portion, and to an uninterrupted subdermal vascular plexus across the midline of the back (supplying the terminal portion). A retrospective analysis of its use in 20 patients, over the last 3 years, suggests that when it is designed properly it can be most useful in the management of sacral pressure sores.

The variability of some motor components of social play and agonistic behaviour in infant eastern coyotes, Canis latrans var.

The duration and stereotypy (in terms of duration) of three actions, stand-overs (SO), generalbites (GB), And scruff-bites (SB), were measured during social play and agonistic interactions in infant eastern coyotes (Canis latrans). The rate of biting was also calculated. We found: (1) SO's and GB's lasted a significantly shorter time during play; (2) when performed during playful interactions, all three acts showed more stereotypy; (3) there was no significant difference between the rates of occurrence of biting during the two situations. A discussion of the 'exaggerated' nature of play behaviour is presented, particularly concerning the form of motor actions that are used during this activity.
