[The development of the torsion angle of the tibia-fibula unit in various age groups].

We studied the torsion angle of the tibiofibular unit in both lower legs of 1588 schoolchildren of both sexes (998 girls and 590 boys), aged between 3 and 18 years divided into four age groups. The torsion angle of the tibio-fibular unit progressively increases with age. Stable values were measured only in the 11-15 years age group. Statistically significant differences of the torsion angle between one lower limb and the other were detected in the girls of the 6-10 and 11-15 age groups, and in the boys of the 6-10 age groups.

[Bilateral habitual fibula head dislocation].

Dislocation of the fibular head is rare. In most of the cases a trauma caused by sports activity, sometimes associated with a tibia fracture, is described. Only a few publications exist about habitual dislocation of the fibular head without history of trauma. This article reports a case of bilateral habitual anterolateral dislocation of the fibular head in a 17-year-old female. There was no information about a neurological or other disease and no sign of generalized ligamentous laxity. Because of marked symptoms with severe pain after each sensation of dislocation which appeared several times a day, the patient was treated by using a part of the biceps tendon for fixation of the reduced fibular head.

Regeneration of the donor side after autogenous fibula transplantation in 53 patients: evaluation by dual x-ray absorptiometry.

We determined the degree of fibular regeneration at the donor site, using radiographs and dual x-ray absorptiometry, in 53 patients who underwent autogenous nonvascularized fibular transplantation for tumor reconstruction in long bones (mean follow-up 15 (3-26) years). Logistic regression was used to determine whether gender, age at transplantation, time since transplantation, bone mineral density (BMD), and length of the graft were associated with fibular regeneration. 26 patients had spontaneous complete bone regeneration. Younger age at transplant was the only predictor of fibular regeneration. In predicting fibular regeneration, sensitivity was 96% and specificity 74%, using 15 years of age as a cut-off. In the long-term follow-up, we found only gradual changes in the BMD and the values ranged from 24% to 217%. We found no correlations of bone mineral density with age, gender, length of the graft, or time since transplantation.

Early treatment of severe mandibular hypoplasia with distraction mesenchymogenesis and bilateral free fibula flaps.

The technique of distraction has revolutionized the treatment of mandibular hypoplasia; however, presently large mandibular defects still require bone grafts. Microvascular grafting is commonly used in adults. Conversely, in pediatric reconstruction, nonvascularized rib grafts remain standard. Unfortunately, resorption of nonvascularized bone remains a major issue, particularly when soft tissue is hypoplastic. This case study represents a combination of techniques in the treatment of severe mandibular deficiency, and introduces the concept of distraction mesenchymogenesis. The patient was a 2 1/2-year-old boy with severe bilateral Pruzansky class III mandibular hypoplasia. He had a permanent open mouth posture, an overjet of 23 mm, and was unable to move the lower mandibular segment. His oropharyngeal airway diameter was 2.2 mm and he was tracheostomy dependent. The patient was treated with distraction of the lower jaw mesenchyme followed by bilateral functional free fibular microvascular flaps containing reinnervated muscle. This created a well-vascularized body, ramus, and condyle bilaterally within an adequate soft-tissue envelope. Postoperatively, the overjet was reduced to 5 mm. The patient can now actively move his mandible. Airway diameter increased to 10 mm, and the patient is able to tolerate intermittent tracheostomy plugging. This innovative combination of techniques allows early intervention, limits graft resorption, and improves airway control.

A retrospective analysis of temporomandibular joint reconstruction with free fibula microvascular flap.

OBJECTIVES: The temporomandibular joint is occasionally encountered in extirpative surgery of the head and neck. It presents a difficult management issue. Little has been reported on functional outcomes after resection and reconstruction of the temporomandibular joint. DESIGN: A retrospective analysis consisting of chart reviews and phone interviews was performed on 17 patients who underwent fibular free flap reconstruction of the temporomandibular joint from 1993 to 1998. RESULTS: Mean follow-up in surviving patients (10) was 41.3 months. Mean age of the group was 62; male-to-female ratio was 11:6. Average hospital stay was 11.6 days. Four patients had no radiation therapy, 2 had preoperative and 11 had postoperative treatment. Five patients had one osteotomy, seven had two, one had three, and one had four. Ten patients could chew, one could not, and none were recorded for the remaining. Diet consisted of regular food for two patients, soft food for seven, full liquids for four, and tube feeds for four. Cosmesis was judged as excellent by eight patients, acceptable by two, and unacceptable by two. Five patients did not describe cosmesis. Most patients stated that bony contour was excellent, but that the soft tissue defect was noticeable. Speech was judged as intelligible by seven and moderately understandable by one. Nine patients did not describe speech. Two patients had postoperative displacement of the fibular head out of the fossa. CONCLUSION: Primary reconstruction of the temporomandibular joint with microvascular fibular flaps is a viable and effective means of restoring function. The majority of patients are able to resume oral feeds, obtain excellent or pleasing cosmetic results, and maintain intelligible speech.
