Fractures of the hand
Published in Peter Houpt, Hand Injuries in the Emergency Department, 2023
This consists of an intra-articular fracture at the base of the fifth metacarpal. Traction of the m. extensor carpi ulnaris pulls the base of metacarpal proximally. Like a regular Bennett fracture, treatment is almost always surgical.

A Bennett fracture is a two-part unstable intra-articular fracture at the base of the thumb metacarpal. The ulnar fragment remains held in place by the volar beak ligament and the metacarpal subluxes proximally (due to the force of abductor pollicis longus) and rotates towards supination (due to the forces of adductor pollicis and flexor pollicis brevis) (Figure 5.8).

Bennett’s fracture is rare but, when it does occur, it usually requires open reduction. This is, by definition, a Salter–Harris type III fracture-separation of the physis; it must be accurately reduced and fixed with a K-wire.

A Bennett fracture is the most common fracture of the thumb [22]. In 1882, Bennett first described the unstable fracture that bears his name [23]. Cannon et al. [24] proposed a simple closed reduction and plaster immobilization to treat this fracture. However, the reported rate of anatomical reduction was 64% [25]. Radiographic osteoarthritis of the CMC joint most likely develops secondary to imperfect reduction and joint incongruity in patients with >1 mm of articular displacement. Livesley [26] reported long-term follow-up in patients with Bennett fractures treated non-operatively. After a mean of 26 years, 12 of 17 patients demonstrated persistent subluxation at the CMC joint and symptomatic arthritis. Thurston et al. [27] reported 21 Bennett fractures treated surgically. After a mean of 7.7 years, patients with <1 mm of displacement demonstrated no degenerative changes.
Management of second metacarpal chronic osteomyelitis by induced membrane technique
Published in Case Reports in Plastic Surgery and Hand Surgery, 2018
Analysis of this series did not find any cases of osteoarticular infection. Our observation is distinguished by the fact that it involved a bone infection secondary to a pinning for a closed Bennett fracture. Inflammatory reactions around osteosynthesis pins are not uncommon in the hand and wrist. They are generally superficial and have a favorable outcome after removal of the pin and topical treatment. The occurrence of chronic osteomyelitis remain difficult complication to treat.
