External fixation and vascular damage: report of a case.

The case history is presented of a patient in whom the anterior tibial artery was clearly perforated by the distal pin of an external fixation device. This necessitated a dorsal pedis free flap instead of transposition of the flap to cover a degloved heel and sole. Review of the literature showed only a few case reports on vascular damage, suggesting that this complication is uncommon. In most cases, secondary erosion seems to be the cause, but as noticed by us direct arterial and/or venous damage is possible.

Management of chronic osteomyelitis of the lower extremity.

Chronic osteomyelitis is a frequent complication after compound fractures of the lower extremity. Essential in the treatment is the radical debridement of all scar tissue, muscle and infected bone. This often creates large tissue defects, which especially in the distal third of the tibia, can only be closed with a free tissue transfer and revascularized by a microvascular anastomosis. Ten patients were operated on for chronic osteomyelitis of the lower extremity. The latissimus dorsi or rectus abdominis muscle was used as a free flap. During the follow-up period (3-18 months) 9 patients have remained free of symptoms of recurrence.

Laser Doppler bone probe in vascularized fibula transfers: a preliminary report.

Continuous monitoring of circulation in bone transfers without a skin element may be possible with a laser doppler bone probe consistent with any free tissue transfer. Immediate reintervention is necessary when vascular insufficiency is suspected. In two clinical cases of vascularized fibula transfer, we were able to compare skin probe recordings with intraosseous probe recordings. There was no apparent difference in the recordings, suggesting that the bone probe alone may be useful for monitoring bone transfers and that it warrants further study.

Glomus tumors of the digits.

A painful subungual tumor in a digit with a cold intolerance is characteristic of a glomus tumor. Lack of recognition often unnecessarily delays therapy. Surgical excision, utilizing an operating microscope for identification of tumor vascularisation and tourniquet control is the therapy of choice. Multiple tumors may be present in the same digit. No malignant transformation of the tumor has been described.

Dietary fat intake and taste responses to fat in milk by under-, normal, and overweight women.

Dietary fat intake, with special emphasis on dairy products, was estimated from questionnaires for 42 underweight, 80 normal weight, and 64 overweight adult women. Frequency of consumption of fresh and processed meats, frozen dairy desserts, pastries, and snacks such as potato chips was greater for the overweight than for the underweight subjects. However, preferences between verbally-described high- and low-fat versions of 14 food pairs did not differ by body size. Overweight subjects reported that they consumed more non-fat milk and less whole milk than did the other groups. Discrimination, perceived intensity, paired preference, and hedonic rating of fat in milk and in chocolate milk did not differ significantly according to body size, fat intake, or type of milk consumed. Ad libitum mixing of non-fat milk and "half and half" (12% fat) to individual levels of liking also showed no significant variation with body size. However, subjects with higher dietary fat intakes mixed to higher fat-preference levels in milk than did the low- and medium-fat intake subjects. Those reporting consumption of regular milk (3.5% fat) mixed to higher fat levels than did those who consumed low-fat (2% fat) or non-fat milk. The ad libitum procedure gave better reproducibility and appeared to be a more realistic measure of liking than the hedonic rating or paired-preference tests.

Creation of an anal sphincter mechanism by bilateral proximally based gluteal muscle transposition.

A case report is given of a girl who, at the age of 17 years, lost her total posterior part of her perineum in a traffic accident. She was left with out an anal sphincter mechanism and a diverting sigmoidostomy was performed. Two years after the accident a new anal sphincter was constructed using bilateral transposition flaps of the gluteus maximus muscles. After 6 months of active training of this new "reanastomosed". The patient thereafter regained complete fecal continence by the natural route.

Bone scintigraphy of experimental composite bone grafts revascularized by microvascular anastomoses.

In these experiments the reliability of bone scintigraphy with 99mTc diphosphonate, to assess anastomotic patency and the viability of revascularized composite fibular grafts, was studied. It was shown that bone scintigraphy is very useful for the diagnosis of anastomotic patency, but only in the first postoperative weeks. Bone scintigraphy gives no information on the viability of bone grafts.
