“…Of the five local recurrences with HA, four were in foot, where the usual barriers to tumor growth are less well bounded than in more proximal parts of the extremity, and tumors arising in these areas became extracompartmental even before they are diagnosed [25]. It is worth mentioning that all four local recurrences in the foot were prior to the assistance of intraoperative navigation, which has shown advantages in complex types of resections [26][27][28], and might be a potential assistance in foot resections.…”

“…This technique solved the problem of creating osteotomies in the allograft to match the host bone. Gerbers et al [21] reported a similar technique at the same time in four patients with hemicortical resections. They used intraoperative navigation for these complex osteotomies for bone tumor resection and the same technique to cut the allograft.…”

Image-guided surgical navigation allows the orthopedic oncologist to perform adequate tumor resection based on fused images (CT, MRI, PET). Although surgical navigation was first performed in spine and pelvis, recent reports have described the use of this technique in bone tumors located in the extremities. In long bones, this technique has moved from localization or percutaneous resection of benign tumors to complex bone tumor resections and guided reconstructions (allograft or endoprostheses). In recent years, the reported series have increased from small numbers (5 to 16 patients) to larger ones (up to 130 patients). The purpose of this paper is to review recent reports regarding surgical navigation in the extremities, describing the results obtained with different kind of reconstructions when navigation is used and how the previously described problems were solved.

“…Daraus leitet sich die Frage ab, ob bei dieser Tumorentität eine subtotale Resektion des tumortragenden Knochensegments onkochirurgisch ausreichend ist und ob diese nach biologischer Rekonstruktion zu funktionell zufriedenstellenden Ergebnissen führt. In der Literatur existieren Berichte über hemikortikale Resektionstechniken [19,20]. Alternativ stellt die totale Resektion des betroffenen Knochenabschnitts mit anschließender tumorendoprothetischer Defektrekonstruktion ein etabliertes und bewährtes Behandlungsverfahren dar [9,11,12].…”

“…Aber auch im Vergleich zu Patienten mit distalem Femurersatz zeigten sich deutlich schlechtere Werte des proximalen Tibiaersatzes in Extension (53 % schlechter) und Flexion (2% schlechter) [17]. Knochenerhaltende Resektionen mit Rekonstruktionen durch autologe und allogene Plastiken sowie Osteosynthese sind zwar beschrieben [18][19][20], werden aber insbesondere bei nachgewiesener Markraumbeteiligung kritisch diskutiert. Liu et al konnten bei 13 parossalen Osteosarkomen mit hemikortikaler Resektion und Rekonstruktion mit Autograft und Plattenosteosynthese gute Ergebnisse erzielen.…”

Juxtacortical osteosarcomas are a group of rare primary bone tumours. They differ from medullary osteosarcomas in their anatomic location (outside of the corticalis), low metastasis rate and better prognosis. The only evidence-based treatment of juxtacortical osteosarcomas is the wide surgical resection. In this technical report we will introduce a new surgical technique, including the subtotal resection of the tumour-bearing bone segment, defect reconstruction by means of an augmenting fixed-angle plate osteosynthesis and homologous cancellous bone graft. If necessary, a subsequent plastic coverage of the soft tissue defect was performed. The technique will be presented by means of three illustrated cases of young patients with juxtacortical osteosarcomas in the proximity of the knee joint. Following diagnostic confirmation by means of an incision biopsy and tumour staging, the three patients underwent this new surgical technique. In the postoperative follow-up and re-staging, two to seven years after surgery, all patients were under complete remission, had functionally restored knee joints (Karnofsky score 90 % or higher) and showed good aesthetic results. The surgical technique described may therefore be an adequate alternative to the complete resection of the tumour-bearing bone segment with prosthetic reconstruction and should be considered on the basis of the illustrated functional results in individual cases.
