Abstract
1. A review of intra-articular and peri-articular fractures of the phalanges has been carried out, and the late results of such injuries have been examined.
2. These fractures usually unite by bone.
3. The results of conservative treatment by immobilisation are satisfactory in the case of mallet fractures, hyperextension sprain fractures and collateral avulsion fractures of the proximal phalanges.
4. The less satisfactory results after collateral avulsion fractures of the interphalangeal joints and avulsion fractures complicating dislocations are discussed.
