Reconstruction of the second metacarpal bone with a free vascularized scapular bone flap combined with nonvascularized free osteocartilagineous grafts from both second toes: a case report

Outcome of Surgical Resection of Primary Malignant and Aggressive Benign Metacarpal Bone Tumors

Primary bone tumors of the hand are relatively rare. Different treatment options have been described in case reports. In this study, the authors present the diagnostic methods and treatment strategies that they used. The goal of this study is to present the oncologic and functional outcomes of surgical resection of primary malignant and aggressive benign metacarpal bone tumors. This retrospective study included 7 patients with primary malignant and aggressive benign bone tumors of the metacarpals who underwent surgical resection with or without metacarpal reconstruction between 2000 and 2017, with a minimum follow-up of 2 years. Clinical and radiologic evaluations were reviewed, and functional evaluation was performed with the Musculoskeletal Tumor Society scoring system. Seven patients (6 female; 1 male), with a mean age of 30.9±11.3 years, were included in the study. Six tumors were de novo, whereas 1 was recurrent. After resection, 5 patients had metacarpal reconstruction. Nonvascularized fibula was used for 3 patients, extracorporeal freezing of the metacarpal using liquid nitrogen was used for 1 patient, and metacarpal shift was used for 1 patient. Mean follow-up was 52.6±26.7 months. At the final follow-up, mean Musculoskeletal Tumor Society score was 27.4±1.6, and no local recurrence was documented. One patient had chest metastasis after 8 years of follow-up. The results show that surgical resection of primary malignant and aggressive benign tumors of the metacarpal bones can achieve satisfactory functional and oncologic outcomes.

Mammoth Giant Cell Tumor of the First Metacarpal: A Case Report and Management Trends

Giant cell tumor (GCT) is classically described as a locally aggressive, epiphyseo-metaphyseal osteolytic tumor occurring in young adults. They are mostly seen in long bones while some are also found in the iliac bone and spine and a very small proportion occurs in hand bones. Due to the rarity of GCT in metacarpal, there is a paucity of treatment options available. In an extensive literature search on PubMed, Embase, Medline, and Ovid from 2004 till date, very few cases were reported.

The various treatment options available are intralesional curettage with or without adjuvant therapy, wide resection, free osteoarticular metatarsal transfer, and, occasionally, ray amputation may also be done. After simple curettage, a reasonably high recurrence rate also imposes comprehensive en-bloc excision, but still, there are many case reports of recurrence.

Experience with a case of GCT of the whole first metacarpal extending from the carpometacarpal to the metacarpophalangeal joint is not thoroughly described in the literature. We hereby report a mammoth GCT of the first metacarpal treated by excision and reconstruction by free fibular graft and adjacent joint fusion with an excellent functional outcome at one-year follow-up.
