Hand lipomas are rare in the hand, and they account for less than 1% of tumors. Osteolipoma is a rare variant of lipoma that is associated with bone metaplasia. It presents as a painless tumor that can cause symptoms when compressing adjacent structures. Magnetic resonance imaging (MRI) is the imaging study of choice. The treatment is surgical resection, with no recurrences being reported. We present the case of a patient with a giant subfascial hand osteolipoma, which, to the best of our knowledge has not yet been reported in the literature.

Posterior dislocations of the metacarpophalangeal joint of the thumb are due to hyperextension trauma and relatively rare. We present the case of a patient in whom closed reduction was not achieved, requiring open reduction and anchoring of the palmar plate with transosseous pull out technique. A literature review focused on treatment was carried out. All authors agree that closed reduction should be the first therapeutic gesture. If this is not achieved, open reduction should be performed through a dorsal or volar approach, and there is no consensus on which is more effective, nor in terms of management of periarticular soft tissues. Reduction in this case was followed by 2-4 weeks immobilization. Results were generally good, restoring a stable and painless joint, although there might be some degree of joint stiffness.
