Giant cell tumor of the metacarpal bones.

Giant cell tumor (GCT) of hand bones is rare. We present two cases of GCT of metacarpal bone. One case was treated successfully with ray amputation. The second patient underwent wide resection and tricortical iliac crest bone grafting. Till the last follow-up (at 26 and 70 months respectively) both patients have been recurrence free and have returned to their previous occupational activities.

Local recurrences after curettage and cementing in long bone giant cell tumor.

BACKGROUND: Giant cell tumor of bone (GCT) is a benign lesion with great propensity for local recurrence. This study aimed to analyse the rates of local recurrence and its possible predisposing factors in Campanacci's Grade III and II GCT of long bones following intralesional curettage and bone cementing. MATERIALS AND METHODS: 32 cases of either sex with Campanacci's Grade II (n= 14), and Grade III (n=18) with intact articular surface, operated between 1995 and 2007 in form of intralesional curettage and bone cementing were studied. All the cases were followed up for 2.5-12 years (mean, 6.5), after primary treatment. The mean age at operation was 32.4 years (range, 18.5-40 years). The proximal tibia was involved in 13 cases (40.6%), followed by distal femur (n=11)34.4% distal tibia (n=3) 9.4%, proximal femur (n=2) 3.2% and distal radius (n=3) 9.4%. RESULTS: Eleven patients (34.4%) had local recurrence, of which eight were of Campanacci's Grade III. The mean recurrence time was 14 months (range, 3-34 months). The two-year recurrence-free survivorship was 71.9% (n=23/32). Post-recurrence mean follow-up was 4.2 years (range, 2-6.5 years). CONCLUSION: We observed higher rate of local recurrence with Campanacci's Grade III GCTs. We recommend selective use of this procedure in Grade III lesions, particularly with extensive soft tissue involvement.

Resection-reconstruction arthroplasty for giant cell tumor of distal radius.

BACKGROUND: Giant cell tumor (GCT) of the distal radius poses problems for reconstruction after resection. Several reconstructive procedures like vascularized and non-vascularized fibular graft, osteo-articular allograft, ceramic prosthesis and megaprosthesis are in use for substitution of the defect in the distal radius following resection. Most authors advocate wrist arthrodesis following resection of distal radius and non vascularized fibular graft. Here we have analyzed the results of aggressive benign GCTs of the distal radius treated by resection and reconstruction arthroplasty using autogenous non-vascularized fibular graft. MATERIALS AND METHODS: Twenty-four cases of giant cell tumor of the distal radius (mean age 32 years, mean follow-up 6.6 years) treated by en-bloc resection and reconstruction arthroplasty using autogenous non-vascularized ipsilateral fibular graft with a minimum followup of two years have been included in this retrospective study. Nineteen cases were of Campanacci grade III and five were of Grade II recurrence. The mean resected length of the radius was 9.5 (8-12) cm. Routine radiographs and clinical assessments regarding pain, instability, recurrence, hand grip strength and functional status were done at regular intervals and functional results were assessed using (musculoskeletal tumor society) MSTS-87 scoring. RESULTS: Early radiological union at host-graft junction was achieved at mean 12.5 weeks, (range 12-14 weeks) and solid incorporation with callus formation was observed in mean 29 weeks (range 28-32 weeks) in all the cases. Satisfactory range of motion (mean 63%, range 52-78%) of the wrist was achieved in 18 cases. Grip strength compared to the contralateral hand was found to be 67% (range 58-74%). Functional results were excellent in six cases (25%), good in 14 cases (58.3%) and four (16.7%) cases had fair results. Soft tissue recurrence was seen in one patient. The most commonly encountered complication was fibulo-carpal subluxation (10 cases, 41.7%). CONCLUSION: Resection of the distal radius and reconstruction arthroplasty with non-vascularized proximal fibular graft is useful in preserving the functional movement and stability of the wrist as well as achieving satisfactory range of movement and grip strength.

Rare site giant cell tumors: report of two cases on phalanges of the finger and review of literature.

Giant cell tumor (GCT) of bone arising from a phalanx of a finger is extremely rare. We report two cases of GCT arising from a phalanx of a finger. One case presented with recurrence following the amputation of the left ring finger (performed elsewhere). He was treated successfully with ray amputation. The other case was treated primarily by intralesional curettage and autogenous bone graft. At their most recent follow-ups (80 and 24 months, respectively), both were recurrence free and had returned to their previous occupational and recreational activities.
