[Biological behavior of a vascularized cortical bone graft. Experimental study of the rabbit fibula].

The study of the biological course of a vascularized osseous graft was performed on 64 fibulae in rabbits. Using radiography, standard histology, tetracyclines markage and study of 47-calcium incorporation as means of control. The time-limits of control are fixed at the 5th, 10th, 15th and 21st day and at the 1st, 2nd, 3rd and 5th month. The results show that if they are vascularized or not, the osseous grafts are not subjected to the rule: everything or nothing: "everything is not living in a vascularized osseous graft and everything is not dying in a conventional osseous graft". As for the good quality of the recipient bed, there is no significant difference between the healing time of those two types of grafts.

Peroneal paralysis due to exostosis of the fibula. Report of 2 cases.

Exostoses in certain situations such as the armpit or the popliteal region, can cause vascular or neurological compression syndromes. Exostoses of the neck of the fibula can in this way produce late paralysis of the peroneal nerve. Two such cases are presented in young patients, in whom the neurological damage was produced by increased growth distally of the neoplasm.

Growth and development of the tibia, fibula, and ankle joint.

Deformities of the leg and ankle may result from growth abnormalities of the tibia and fibula. Measurements of the distance between the proximal tibial and fibular physes, the distal tibial and fibular physes, and the angle between the long axis of the tibia and the distal tibial physis and talar dome were made to determine the changes that occur during normal skeletal development. These measurements demonstrate that early detection of growth discrepancy is possible.

Effect of estradiol benzoate on the proliferation of osteogenic cells in fetal rat fibulae cultured in vitro.

The influence of estradiol benzoate on the proliferation of bone cells was investigated in vitro by radioautography. The fibulae from 19-day fetal rats were pulse-labeled with 3H-thymidine after various periods of culture on estrogen-supplemented (5 microgram/ml) or control media. The analysis of radioautographs revealed that the cell division was restricted to osteogenic cells of undifferentiated appearance. No label was found in osteoblasts or in osteoclasts. At the time of explantation, about 30% of osteogenic cells were labeled. However, this percentage varied considerably after different intervals of culture. In the control bones, it decreased during first 12 hours to 15% and then rose slowly to attain a preculture value after 48 hours. In the presence of estradiol, the initial decline of labeled cells was less pronounced. The percentage recovered to a preculture level already after 24 hours and continued to increase thereafter. The numbers of labeled osteogenic cells, in estrogen-treated bones, were significantly higher than in controls already after 12 hours of culture. It is concluded that the fetal rat bones undergo in vitro a period of adaptation to a new environment as indicated by a transient decrease of dividing cells. Estradiol benzoate appears to shorten this period by stimulating the proliferation of undifferentiated cells.

Osteofibrous dysplasia of the tibia and fibula.

Osteofibrous dysplasia of the tibia and fibula is not a well recognized entity. We have seen thirty-five patients with the disease. Twenty-two comparable cases have been reported in the literature with such diagnoses as ossifying fibroma, congenital fibrous dysplasia, and congenital fibrous defect of the tibia. The main differential diagnosis is with fibrous dysplasia and with adamantinoma of a long bone. Twelve of our patients had long-term follow-up and some of the lesions regressed spontaneously. Osteofibrous dysplasia seldom has even a moderate tendency to progress during childhood, but it recurs frequently after curettage or subperiosteal resection. Such recurrences generally are moderately progressive or not progressive at all. Any progression of the lesion comes to an end after puberty. Attempts at radical surgery either primarily or after recurrence do not seem to be necessary. Surgery should be delayed as long as possible and should be restricted to extensive lesions. The results of surgical treatment usually are good even in patients with a recurrence, fracture, or pseudarthrosis.

Midline metatarsal dysplasia associated with absent fibula.

In 5 patients with congenital deficiency of the fibula, the degree of fibular deficiency ranged from unilaterally short to bilaterally absent. The patients each had at least one missing metatarsal and, in addition, dysplasia of a midline metatarsal. In view of these findings, some missing metatarsals associated with congenital fibular deficiency could be midline metatarsals. The abnormality could represent a deficiency acquired after the development of the embryonic limb bud cartilage models.

[Free transplantation of a fibula with epiphysis].

Problems of free bone transplantation, as well as those of bone transplantation by microvascular anastomoses are exemplified by a case of free fibula transplantation--the epiphysis being conserved--by microvascular anastomoses. If revascularisation of the bone transplant is immediately achieved, the chance for survival of bone tissue is improved and there is a chance that the epiphysis will retain the capacity to grow. By multiple surgical interventions the stability of the abnormally mobile forearm was reestablished and considerable lengthening of the shortened skeleton was achieved. By tendon and nerve transplantations simple grasp could be restored to the hand which originally was without function.

Fibula free flap mandibular reconstruction.

The fibula free flap is rapidly becoming the donor site of choice for mandibular reconstruction. Its versatility makes it suitable for the majority of composite mandibular defects. The indications, operative techniques, and postoperative considerations are detailed in this article. Important principles of preoperative preparation, flap design, graft shaping, and bone fixation are included.

Fracture-dislocation of the ankle with fixed displacement of the fibula behind the tibia.

Fracture-dislocation of the ankle with fixed displacement of the fibula behind the tibia (Bosworth fracture-dislocation) is infrequently encountered in clinical practice. The diagnosis of this entity is often overlooked due to an inability to correlate clinical findings with roentgenographic data. The mismanagement that follows an incorrect diagnosis may render a patient permanently disabled. The authors report a case of Bosworth fracture-dislocation and describe the steps leading to proper diagnosis and treatment of this rare injury.

Bifocal fractures of the tibia and fibula. Incidence, classification and treatment.

We report the results of a three-year study of bifocal fractures of the tibia and fibula, excluding segmental shaft fractures. In our whole series, these formed 4.7% of all tibial diaphyseal fractures. We describe three groups: bifocal fractures of both the proximal and the distal joint surfaces, fractures of the shaft and tibial plateau, and fractures of the shaft and ankle. These groups of fractures had different characteristics and prognoses. We discuss treatment protocols for each of these three groups.

[Ipsilateral inverse fibula transposition for treatment of congenital tibial pseudarthrosis].

Congenital pseudarthrosis of the tibia is one of the most challenging problems in reconstructive surgery. A wide variety of surgical methods has been utilised to treat this condition: One is the free transposition of the vascularised fibular segment to bridge the gap of pseudarthrosis. The authors report their experience in using a vascularised pedicled fibular segment of the ipsilateral fibula with reverse peroneal flow. Three patients were treated successfully. Progressive hypertrophy of the grafts without resorption was demonstrated. Within one year, all children were able to walk without an orthesis.

[Threatened fibula fracture by transosseous migration of a leaded glass fragment].

A case of a 24-year-old man is reported: At the age of ten he was injured by a pane of glass in the region of the medial ankle joint. 14 years later a piece of broken glass which was overlooked during wound toilet, had penetrated to the lateral ankle. The foreign body was impacted in the distal fibula which was sensitive to pressure. Our case shows the importance of a careful inspection of every wound. An unrecognized foreign body may cause severe complications later on.

Growth of the tibia and fibula bones in human fetuses.

The growth of the long bones has been a subject of great importance lately, because it provides non invasive diagnosis of prenatal malformations. This study examines 116 tibia and fibula bones of Brazilian fetuses (17 males and 12 females) with gestational age ranging from the 16th to the 34th week postconception. Only fetuses with no visible congenital malformations and with normal biometric parameters were considered. The bones were measured with a 0.1 mm precision caliper and their Total Length (TL), the Ossified Diaphysis Length (ODL), the Diaphysis width (DW), the Proximal Epiphyss length (PEL) and the Distal Epiphyss Length (DEL) were studied. The Total Length (TL) and the Ossified Diaphysis Length (ODL) were correlated with those of the fetal Crown-Rump length (C-R). Our results have shown that there was an increase in all these measures, with no significant statistical difference observed between the left and the right sides. A significant correlation coefficient was found in most parts of the measurements studied. This study aims to provide data to be utilized in monitoring bone growth as well as in the diagnosis of the lower limb deformities during fetal period.

[False aneurysm of the posterior tibial artery complicating fracture of the tibia and fibula].

PURPOSE OF THE STUDY: Although tibia and fibula fractures are common, associated injury of the posterior tibial artery is rare. We present an unusual case of pseudoaneurysm of posterior tibial artery complicating a closed tibial and fibular fracture. MATERIAL: A 21-year-old man injured his left leg while playing football. METHOD: The diagnosis was suspected by the presence of persisting painful swelling at the fracture site. Echography, and later angiography confirmed it. RESULT: The patient was successfully treated with a saphenous vein interposition graft. The tibial fracture was stabilized with a Küntscher nail, and five months after surgery the fractures healed. DISCUSSION: A review of the literature revealed only 11 civilian cases of pseudoaneurysm of the posterior tibial artery. The clinical signs, specific diagnosis and operative treatment are discussed. CONCLUSION: Our case emphasizes that attention must be paid to the vascular complications of fractures, that may not become evident until some time after the initial injury.

[Fracture dislocation of the ankle with retro-tibial luxation of the fibula (Bosworth fracture) . Apropos of a case].

The authors present a case of fracture dislocation of the ankle joint with the proximal part of the fibula entrapped behind the tibia ; Bosworth's fracture. This fracture was described for the first time in 1848 by Hugier, and classified by Bosworth in 1947. In our case, diagnosis was not done in a first time, and closed reduction failed. This fracture was operated on and open reduction was performed. At the present time, the functional result is good.

Triplane fracture associated with a proximal third fibula fracture.

The case of a Maisonneuve fracture occurring in association with a triplane fracture in an adolescent wrestler is presented. In this combination of injuries, the deltoid ligament may be ruptured, and/or the medial malleolus fractured. If the proximal fibula fracture is not discovered, and the syndesmosis rupture is not treated, the resulting chronic talocrural instability may lead to chronic ankle pain and degenerative arthritis. The orthopedist should be aware of the possibility of a Maisonneuve fracture occurring in association with a triplane fracture, and should treat both injuries appropriately.
