A right-handed man with an enlarging bony swelling of his dominant hand developed symptoms of median and ulnar nerve compression. He underwent simple excision of the hamate and histology showed the lesion to be a benign chondroblastoma. At 2-year follow-up he was found to be doing a heavy manual job with no functional problems and there were no signs of recurrence of the tumour. To our knowledge this is the first reported case of a benign hand tumour treated by simple excision of the hamate.

Article Synopsis
- This review compares the outcomes of two surgical treatments—open reduction internal fixation (ORIF) and excision—for hook of hamate fractures, focusing on recovery and complications.
- The study analyzed 27 articles, finding that excision led to quicker return to sports and lower postoperative pain, but also higher rates of ulnar nerve dysfunction compared to ORIF.
- The conclusion suggests both methods have acceptable outcomes, but more extensive studies are needed to determine the best surgical approach for these fractures.
