Objective: To assess whether hemicortical excision and biological reconstruction instead of the conventional wide resection for selected cases of malignant surface tumors, may give adequate oncologic clearance with less morbidity and better function.

Methods: From January 2000 to June 2007 a total of 29 malignant surface tumors were managed at our institute. Fifteen of these were treated with hemicortical excision and reconstruction. They consisted of 10 parosteal osteosarcomas, 1 periosteal osteosarcoma, 1 high grade surface osteosarcoma, 1 adamantinoma and 2 surface chondrosarcomas. Nine were in the distal femur, 3 in tibia, 2 in the humerus and 1 in the radius. Four of these were residual/recurrent lesions following earlier intervention. After hemicortical excision with adequate margins the bone defect was reconstructed with allograft/autograft and suitable internal fixation where indicated.

Results: Margins were reported free in all cases. There were no infections. Three of five patients who did not have fixation with a plate at index surgery sustained a subsequent fracture which was then reduced and fixed. Follow up duration was from 24 to 90 months. Two patients had isolated soft tissue recurrences. Both underwent re excision and are currently disease free at 36 and 38 months respectively after recurrence. Eleven patients had a maximum possible score of 30 (MSTS functional scoring); other four had a score of 29. None of the cases have developed distant metastasis.

Discussion: Early results indicate that in selected cases, hemicortical excision is an oncologically sound procedure. The ability to do a biological reconstruction with bone helps avoid some of the serious complications of a megaprosthetic reconstruction while permitting full active loading of the extremity and near normal function. Internal fixation at index surgery permits early mobilization and minimises the incidence of subsequent fractures.

Objectives: To analyse functional outcome of giant cell tumor (GCT) distal radius treated with en bloc excision and reconstruction with ulnar translocation and wrist arthrodesis.

Methods: Between June 2005 and March 2008 fourteen patients of Campanacci grade 3 GCT distal radius treated with en bloc excision were reconstructed with ulnar translocation (radial transposition of ulna) and wrist arthrodesis. Seven (50%) patients had recurrent disease. Average resection length was 7.9 cm (range 5.5cm–15 cm). Twelve cases were fixed with a plate and in 2 an intramedullary nail was used. Union at both junctions was evaluated and functional assessment done using MSTS score.

Results: All 14 patients had followed up till bony union. Eleven patients were available at time of final review with an average follow up of 24.5 months (range 13–48 months). Average time for union at ulnocarpal junction was 4 months and ulnoradial junction was 5 months. No case required any additional procedure to augment union. Three cases had a soft tissue recurrence and one had pulmonary metastasis. Average range of prono supination was 80 degrees, one patient with synostosis had complete restriction of prono supination. Average MSTS Score at last follow up was 26 (86.6%).

Conclusions: Ulnar translocation provides a local vascularised bone graft to bridge the defect after excision of distal end radius tumors without the need for microvascular procedures. Unlike centralization of the ulna it retains prono supination while maintaining good hand function.

Between June 2005 and March 2008, 14 patients with a Campanacci grade-3 giant-cell tumour of the distal radius were treated by en bloc resection and reconstruction by ulnar translocation with arthrodesis of the wrist. The mean length of radius resected was 7.9 cm (5.5 to 15). All the patients were followed to bony union and 12 were available at a mean follow-up of 26 months (10 to 49).

The mean time to union was four months (3 to 7) at the ulnocarpal junction and five months (3 to 8) at the ulnoradial junction. All except one patient had an excellent range of pronation and supination. The remaining patient developed a radio-ulnar synostosis. The mean Musculoskeletal Tumor Society score was 26 (87%, range 20 to 28). Three patients had a soft-tissue recurrence, but with no bony involvement. They underwent a further excision and are currently well and free from disease.

Ulnar translocation provides a local vascularised bone graft to reconstruct the defect left after excision of the distal radius for giant cell tumour. It avoids the need for a microvascular procedure while retaining rotation of the forearm and good function of the hand.

We evaluated the results of fibular centralisation as a stand alone technique to reconstruct defects that occurred after resection of tumours involving the tibial diaphysis and distal metaphysis.

Between January 2003 and December 2006, 15 patients underwent excision of tumours of the tibial diaphysis or distal metaphysis and reconstruction by fibular centralisation. Their mean age was 17 years (7 to 40). Two patients were excluded; one died from the complications of chemotherapy and a second needed a below-knee amputation for a recurrent giant-cell tumour. A total of 13 patients were reviewed after a mean follow-up of 29 months (16 to 48). Only 16 of 26 host graft junctions united primarily. Ten junctions in ten patients needed one or more further procedure before union was achieved. At final follow-up 12 of the 13 patients had fully united grafts; 11 walked without aids. The mean time to union at the junctions that united was 12 months (3 to 36). The mean Musculoskeletal Tumor Society Score was 24.7 (16 to 30).

Fibular centralisation is a durable reconstruction for defects of the tibial diaphysis and distal metaphysis with an acceptable functional outcome. Stable osteosynthesis is the key to successful union. Additional bone grafting is recommended for patients who need postoperative radiotherapy.
