Abstract

BACKGROUND: Originally described as osteochondromatous lesions arising from the tarsal bones, osteochondromas arising from the epiphysis or carpal/tarsal bones are less common than those arising from the metaphysis. Histologically, all osteochondromas are indistinguishable regardless of the location from which they arise. Few case reports and case series exist describing these lesions in the upper limb. METHODS: We review 7 cases of osteochondromas arising from epiphyses and ossicles in the upper limb treated at 3 institutions. Patients were followed for an average of 5.7 years. The average patient age at the presentation was 7.8 years. RESULTS: We identified 25 lesions: 5 distal radial epiphyseal, 3 distal radial metaphyseal, 4 scaphoid, 4 lunate, 4 trapezial, 2 accessory ossicles adjacent to the trapezium, 2 trapezoid, and 1 metacarpal lesion. Three patients presented with pain, 5 with decreased motion, and 3 with angular deformity. In 1 case, the lesion presented as an incidental finding. Four patients underwent a total of 7 procedures: 2 open biopsies, 2 distal radial epiphyseal lesion excisions, 2 revisions, and 1 excision of all lesions with a scaphoid osteotomy. CONCLUSIONS: Intra-articular and transosseous lesions are more likely to result in angular deformities and loss of motion at the joints, whereas juxtaphyseal and transphyseal lesions are more likely to result in growth disturbances and angular deformities at the physis. LEVEL OF EVIDENCE: Case series, level IV.
