[Vascularized fibula transplantation in orthopedic oncology. Personal experience and review of the literature].

Primary malignant bone tumors can be treated predominantly with limb salvage. After resection of large articular segments adjacent to the dia- or metaphysis of long bones modular endoprosthetic devices are most commonly used for reconstruction. In case non-vascularized corticocancellous bone is transplanted in order to bridge extensive bone defects, the risk of pseudarthrosis and fracture of the donor bone is significantly higher in comparison to a free vascularized transplant. From 1988 until 1999 we treated 20 patients with extensive bone defects after resection of tumors affecting the upper and lower extremity using a vascularized fibular graft. In this retrospective analysis we collected the data focusing on bone integration and functional outcome. The graft union was classified according to the standards of the "International Symposium of Limb Salvage". Evaluation of the functional outcome was quantified using the Enneking-score. The stabilisation of the transplant was obtained exclusively by plate fixation in the upper extremity. In 10 in a total of 12 patients the reconstruction using a vascularized fibula transfer was reinforced with an allograft in the lower extremity. The functional evaluation score reached 73% of normal function at the last follow-up. After 18 months the radiographic evaluation of graft union was "excellent" in 75%, "good" in 11%, "fair" in 6% and "poor" in 9% according to the criteria of the ISOLS. Main complications were graft fracture in of 15% and pseudarthrosis in 14.3%. Reconstruction of extensive bone defects using free vascularized fibula grafts are a demanding operative procedure. The procedure combines a biologic form of reconstruction with a legitimate expectation of good long term outcome and a relatively low rate of complications.

Congenital (infantile) pseudarthrosis of the fibula associated with osteofibrous dysplasia.

We describe a recently noted association of congenital (infantile) pseudarthrosis of the lower leg with osteofibrous dysplasia. The patient was a 2-year-old boy who presented with a deformed left ankle joint and three cutaneous cafe-au-lait spots. Radiography demonstrated pseudarthrosis of the left distal fibula and a round lucent lesion adjacent to the proximal part of the pseudarthrosis. Histologically, the surgically removed fibula with pseudarthrosis showed a fibromatosis-like fibrovascular proliferation and nonspecific reparative changes. The focal lucent area demonstrated a fibro-osseous lesion, which was histologically identical to osteofibrous dysplasia. This case provides further evidence that osteofibrous dysplasia may be associated with congenital (infantile) pseudarthrosis of the lower leg.

Transplantation of the proximal fibula based on the anterior tibial artery. Anatomical study and clinical application.

The purpose of this study was to investigate the feasibility of microvascular transplantation, based on the anterior tibial artery, of the epiphysis and the proximal half of the diaphysis of the fibula. India ink injections into the anterior tibial artery were performed in 13 unembalmed adult cadavers, following which transverse frozen sections were taken. Dye was observed in the fibula, both within the intramedullary cavity and at the level of the periosteum, in all specimens. The average distal limit reached by the dye, measured from the tip of the epiphysis, was 10.4 cm in the intramedullary cavity and 11.8 cm in the periosteum. Based on these anatomical findings one case of humeral reconstruction has been performed with a fibular transplant, including both the epiphysis and a segment of diaphysis, vascularized solely by the anterior tibial artery.

Painful non-union of the fibula in football player following fracture of the leg.

We report the case of a young football player operated on for a middle shaft fracture of the right leg with a Kuntscher nail. After 8 months, when he started to play football again, he suffered from a painful pseudoarthrosis of the region at the transition from the median to the lower third of the fibula. Because of the severity of the pain, and due to the lack of a well-defined and stated surgical option, a subtraction osteotomy was performed in order to remove the cause of the ache. The patient was revisited 3 and 6 months later, and showed complete disappearance of the pain and a full return to sport activities. In light of the good result obtained, we consider the osteotomy operation a reliable and easy-to-perform method in treating non-unions of the fibula.

Intentional marginal excision of osteosarcoma of the proximal fibula to preserve limb function.

Three cases of osteosarcoma (stage IIB) of the proximal fibula were successfully treated by marginal excision that preserved the common peroneal nerve and lateral stabilizers of the knee joint. Caffeine-assisted chemotherapy was administered to three boys, ages 15, 17, and 11 years, and resulted in a complete response. Two patients initially presented with peroneal nerve palsy that resolved completely with preoperative chemotherapy. The subsequent intentional marginal procedures resulted in preservation of the common peroneal nerves, lateral collateral ligaments, and biceps femoris tendons. In two cases the collateral ligament and biceps tendon were reattached to the tibia with a spike washer or suture anchors, and in the third case they were reattached by suture only to the ligamentous and capsular structure of the tibia. All three patients have normal ankle and knee joint function without evidence of recurrence 122, 120, and 61 months after surgery, respectively. Preservation of limb function without compromising the principles of tumor surgery is a desirable goal in any patient but particularly in young patients. For patients with osteosarcoma of the proximal fibula, this approach provides a better quality of life than conventional wide excision.

Donor site morbidity after microvascular fibula transfer.

The free microvascular fibula and soft tissue transfer has become a widely used method to reconstruct the head and neck region. Only few reports focus on the donor site morbidity of purely mandibular reconstructions. On the basis of the hospital charts, a standardized patient interview and a standardized physical examination, the present study evaluates the early and late donor site morbidity in 42 mostly oncologic patients after an average follow-up interval of 34 months. Of these, 16 patients (38.1%) exhibited complicated wound healing that did not correlate with the patient's age, sex, type of transplant, use of a skin graft, result of preoperative angiography, rate of postoperative mobilization or the incidence of late donor site morbidity. At the time of follow-up examination, about one-fourth of the patients reported discomfort, pain or swelling. Objective findings included sensory deficits in 76.3%, motor deficits in 39.5% and reduced strength in 44.7% of the patients. Even though objectively measured morbidity exceeded subjectively perceived morbidity, it can be concluded that there is significant early and late donor site morbidity, which should be considered when opting for a fibula graft. Patients should be informed accordingly.

The morbidity of the free vascularised fibula flap.

Twenty patients who had undergone free vascularised fibula flap transfers were reviewed to determine the incidence of peri and postoperative complications. The mean follow-up was 3.2 years (0.2-10); 18 grafts were successful, but required 10 re-operations for complications including 5 haematoma evacuations and 3 bone grafts and plates for delayed or non-union. The two unsuccessful fibula grafts required 11 re-operations, the majority for infections and non-union. Technical details of the operative procedure are reviewed for their part in the complications.

New reconstruction for total maxillectomy defect with a fibula osteocutaneous free flap.

The osteocutaneous fibula free transfer with three segments of bone and the peroneal flap was used to reconstruct a total unilateral maxillectomy defect. Satisfactory restoration of three-dimensional facial structure, orbital support, and prosthesis wearing was achieved. The fibula osteocutaneous free flap is a very useful alternative for reconstructing a maxillectomy defect.

The versatility of the free fibula flap in the management of traumatic long bone defects.

The free fibula flap has been used to treat ten patients with important long bone defects (mean length 14 cm) following severe trauma. Defects in all the long bones of the limbs have been treated by this technique. Five free osseous and five osteocutaneous flaps were performed. Primary skeletal union occurred at 17 bone junctions (85 per cent) within 5 months. No secondary grafting procedures were required. The mean delay in referral was 17 months and eight patients had already undergone three or more unsuccessful surgical procedures to promote union. The versatility of the vascularized free fibula flap is presented as a one-stage reconstruction for large bony and soft tissue defects, stressing the importance of prompt referral and recognition of cases. A combined orthopaedic and plastic surgical approach to these patients is advisable from the onset.

The intact fibula.

The notes and radiographs of 281 adult tibial shaft fractures were reviewed. In 17 per cent there was an intact fibula. Delayed union rates were lower when the fibula remained intact, thus confirming that this is a good prognostic indicator. This fracture is caused by less severe trauma than fractures where both bones are broken. It is rare over the age of 30 years.

Assessment of tibial stiffness by vibration testing in situ--II. Influence of soft tissues, joints and fibula.

The influence of soft tissues and joints on the vibration of the human tibia was examined by modal analysis on amputated lower limbs, where the soft tissues and the fibula were dissected gradually. Measurements were made in two different set ups, IFR and BRA, which were both designed to monitor fracture healing. In IFR, vibrations are generated by hammer impact on a relaxed hanging lower leg, with the knee flexed. Resonant frequencies are determined by a computer Fourier transform procedure. In BRA, a steady state vibration is induced in a lower leg, supported near the ankle and the tibial tuberosity, using an electromagnetic shaker. Resonant frequencies are determined from the maxima in vibration amplitudes. In both set ups the soft tissues have a similar influence on the vibration of the tibia: the skin hardly influences the determined modal parameter. The mass of the muscles influences both the resonant frequency and the damping. The fibula has a stiffening effect on the tibia. The influence of the joints is small in the IFR-set up: the tibia vibrates in conditions close to those for the free-free vibration. In the BRA-set up, the supports determine the boundary conditions.

Evaluation of fibula free flap donor site morbidity.

OBJECTIVE: To evaluate foot and ankle function in a series of patients undergoing fibula microvascular free tissue transfer. STUDY DESIGN: A nonrandomized, nonblinded analysis was performed using the ankle-hindfoot scale as well as radiographic analysis to determine donor site morbidity. RESULTS: Overall, foot ankle function was deemed to be good in this series of patients. Average ankle-hindfoot score was 84.82 of a possible 100 (range, 55-100). Radiographic analysis of donor and contralateral ankles showed no difference in the syndesmotic space or medial clear space. Only 1 patient had increased talar tilt compared with the contralateral side, although this patient had preservation of stability. CONCLUSION: Fibula free flap harvest appears to be associated with acceptable donor site morbidity and preservation of good foot and ankle function in most individuals.

[Donor site morbidity after free fibula flap. Report of 42 consecutive cases].

Donor site morbidity after free fibula flap was assessed in 42 patients, 37 of whom had undergone mandibular reconstruction and five proximal humerus. Lower limb reconstructions were excluded. The study comprised functional assessment with two international orthopaedic scales (Karlsson and Kitaoka); comparative lower limb clinical and X-ray assessment. Mean Karlsson score was 90.4/100 with 52% of excellent, 36% of good, and 12% of medium results. Mean Kitaoka score was 93.7/100 with 64% of excellent, and 36% of good results. Fifty-two percent of patients were pain free, 29% had pain on walking on uneven terrain, and 19% occasionally; 7% experienced instability. For 76%, physical activity was unrestricted. Clinical examination found no alteration in hindfoot axis, no joint laxity, mild and acceptable reduction in hallux plantar flexion power in 76% cases, and superficial fibular nerve hypoesthesia in 5% of cases. Methodology and results are detailed and compared to the literature. In conclusion, we found only slight morbidity and free fibula flap remains our first choice as bone flap.

[Mandibular reconstruction: conduct of osseous integrated implants of iliac crest and fibula free laps].

Reconstruction of the mandible osseous defects following radical ablation is usually carried out by means of vascularized f. Plapsossible donor sites often include fibula, radius, scapula and iliac crest. In the present report, we raise our experience of 45 cases of osseous reconstruction of the mandible utilizing the iliac crest (35 patients) and the fibula (10 patients). Patients were selected to this study based on the presence of purely osseous defects and evaluated functionally after the inclusion the osseous integrated implants.

An unreported variation of the course of peroneal artery during fibula flap harvest.

We describe a previously unreported anatomical variant of the peroneal artery that was found both on preoperative angiography and at operation to be related to the fibula only in its distal third. In contrast to previously reported variations, the artery began descending on the medial aspect of the fibula about 26cm from the fibular head.

Tibial stress fracture as a complication of free-fibula vascularised graft for mandibular reconstruction.

The free vascularised fibula graft is used for a variety of reconstructive procedures and is frequently associated with donor site morbidity. Non-traumatic stress fracture to the tibia following a vascularised free-fibula graft is an uncommon but important complication. The diagnosis may be missed if radiological "stress views" of a possible fracture site are not performed, which may result in its underreporting. The authors report a case in which the aetiology, diagnosis and management recommendations are presented for discussion.

Flow-through anterolateral thigh flap for a free osteocutaneous fibula flap in secondary composite mandible reconstruction.

Head and neck reconstruction after tumour ablation and radiotherapy often requires complex surgery. The need for free composite tissue transfer and the poor quality of the recipient site increase the level of difficulty substantially. We report a case in which the mandible, floor of the mouth and skin of the neck needed to be reconstructed in a heavily irradiated field. A single osteocutaneous fibula flap was insufficient to reconstruct the defect, and a free anterolateral thigh (ALT) flap was also used for external neck skin resurfacing. As the recipient vessels in the ipsilateral neck had been heavily irradiated the free ALT flap was used as an interposition conduit for the free osteocutaneous fibula flap enabling it to reach the healthy recipient vessels in the contralateral neck without needing vein grafts.

Vertical distraction of fibula transplant in a case of mandibular defect caused by shotgun injury.

This case demonstrates the successful aesthetic and functional reconstruction of a complex facial gun-shot injury with extended bone defects and soft tissue destructions using a 3-step procedure. Initially, a reconstruction plate was inserted, later a fibula transplant enabled the basic reconstruction and finally was distructed in a 3rd session. The rationale behind the sequencing of surgical sessions was the extended bony defect and soft-tissue destruction. The main problem in this type of wound is hypoxia or anoxia of the receptor bed for the transplant. A microvascular anastomosized bone transplant is necessary for sufficient oxygen tension in the recipient site. The anatomical dimensional disproportion of the transplanted free fibula graft and the shape of the mandible were corrected prior to the insertion of dental implants by means of vertical distraction.
