Giant cell tumor (GCT) of the bone is a benign, locally aggressive neoplasm that has a high tendency for local recurrence. It usually has a higher incidence in the third decade of life. This is a retrospective review of a case with histologic confirmation of GCT in a skeletally immature patient involving the metatarsal bone, which is a rare site. At our institution, 1.3% of skeletally immature patients had GCT of the bone. From an extensive literature review, only four cases of GCT of the metatarsal bone in the skeletally immature were identified. Giant cell tumor in a skeletally immature patient can be confused for an aneurysmal bone cyst because of similar radiologic findings. Giant cell tumor of the bone can occur in an immature skeleton and should be sought out as a differential diagnosis despite being rare.
Treatment of Hallux Valgus with Three-dimensional Modification of Mitchell’s Osteotomy
Technique and Results
Mitchell’s osteotomy gives very good results but there are still some cases where the original method, as well as its modification, cannot address all aspects of deformity. We modified the original Mitchell’s method to address pronation and plantar displacement of the first metatarsal. Modification includes formation of lateral and plantar spur with metatarsal displacement and derotation of distal metatarsal fragment in the frontal and horizontal planes with stable screw fixation. We present midterm results of the first 60 patients compared to the original Mitchell method (30 patients). Differences between the groups postoperatively were in declination angle, postoperative metatarsalgia rate, and first metatarsal pronation angle. The technique described eliminated many of the disadvantages of Mitchell’s method. (J Am Podiatr Med Assoc 99(2): 162–172, 2009)
