Campanacci Grade 2 or 3 Giant Cell Tumor of the Phalanges: En Bloc Resection and Matched Nonvascularized Toe...

The goal of the study was to assess the result of en bloc resection and matched nonvascularized toe phalangeal transfer in Campanacci grade 2 or 3 giant cell tumors of the phalanges.

Seven patients with Campanacci grade 2 and 3 phalangeal giant cell tumors were treated by en bloc resection and matched nonvascularized toe phalangeal transfer between June 2004 and May 2021. The patients were followed up by X-rays, Patient-Rated Hand and Wrist scores, Foot Function Index, Quick Disabilities of the Arm, Shoulder, and Hand questionnaire, and total active motion measurements.

The minimum follow-up was 18 months (range: 18-230 months; mean: 110 ± 81). There were three males and four females, with age ranging from 13 to 48 years (mean: 24.14 ± 11.74). The right:left hand ratio was 3:4. The thumb was involved in one patient, the index finger in two, the middle finger in one, and the ring finger in three patients. The mean total active motion was 201.70 (range: 190°-240°). The mean patient-rated hand and wrist score was 15.2 (range: 10-35). The mean quick disabilities of the arm, shoulder and hand questionnaire score was 1.3 (range: 0-9). The mean foot function index on follow-up was 2.86 (range: 2-3). There was no tumor recurrence. One patient had a pathological fracture with resultant shortening of the finger on follow-up.

In our series en bloc resection and matched nonvascularized toe phalangeal transfer resulted in a functional tumor-free digit with a low complication rate and no recurrences.
