Background: Floating metacarpal is a rare concurrent bipolar dislocation of metacarpal at both ends. Isolated dislocations of Carpo-metacarpal (CMC) or Metacarpo-phalangeal (MCP) have been previously reported, simultaneous dislocations of both joints is scarcely reported in literature and bares high chance of diagnosis being missed on presentation.

Patient: A 29-year-old male presented with pain, swelling in left hand and loss of movement in fifth and fourth finger following a motorcycle fall injury. Read More

Ulnar-sided carpometacarpal (CMC) joint fracture dislocations are relatively uncommon, frequently associated with fractures of the metacarpal base and/or hamate, and often sustained by young male individuals secondary to striking a hard object. The complexity of ulnar-sided CMC fracture dislocations necessitates careful restitution of anatomic alignment and joint congruency for mobility and stability. Miniaturization of the external fixation device has allowed application to the hand. Read More

Old fractures and dislocations of the base of the fifth metacarpal may result in post-traumatic arthrosis which is troublesome from a functional point of view and characterized by a difficult management. Stabilized arthroplasty is based on arthroplastic resection of the base of the fifth metacarpal associated with lateral diaphysometaphyseal arthrodesis between the fourth and the fifth metacarpal. This study involving two patients aimed to describe the advantages and the peculiarities of stabilized arthroplasty compared to other techniques in the treatment of the sequelae of fractures and dislocations of the base of the fifth metacarpal.

Injuries of the carpometacarpal joints of the long fingers are infrequent and go often unnoticed if a thorough clinical exploration and complete radiological assessment is not carried out. The overall frequency of carpometacarpal joints injuries is of 1-2% among trauma of the wrist and the carpus. These are normally secondary to high energy trauma (such as a car or a motorbike accidents). Read More

A Bennett fracture is a common injury that involves an intra-articular fracture at the base of the first metacarpal. This fracture typically results in a dorsally and radially displaced metacarpal shaft relative to the well-anchored volar ulnar fragment. Most Bennett fractures are treated with operative fixation, including closed reduction and percutaneous fixation, open reduction and internal fixation, or arthroscopically assisted fixation.

Incorrect or delayed diagnosis and treatment of the carpometacarpal fracture-dislocations is often associated with poor prognosis. We present a rare case of unusual pattern of injury, involving dorsal dislocation of four ulnar carpometacarpal joints, associated with fracture of the trapezium, a burst fracture of the trapezoid  bone and an extra-articular fracture of the third distal  of the radius.

We propose a method for open reduction and internal fixation of early and unstable ulnar (fourth and/or fifth) carpometacarpal joint (CMCJ) fracture subluxations or dislocations using a dorsal buttress plate. In ulnar CMCJ fracture dislocations, the metacarpal has a tendency to displace dorsally and proximally when there is an axial load. Using the dorsal buttress plate method of fixation, a plate is fixed proximally to the hamate, aligned parallel and dorsal to the metacarpal to act as a buttress, to resist this movement. Read More

Introduction: Double dislocation of thumb metacarpal (MC) is a rare injury which may be secondarily complicated by growth plate injury in children. The management of floating 1st MC is also controversial since the treatment ranges from simple reduction to complex reconstruction surgeries. It is also important to understand the long-term results of different management strategies (close reduction, K-wire fixation, ligament reconstruction) as any residual stiffness or instability of thumb may result in severe disability of the hand.

Our aims were to evaluate the use of locked K-wire fixation for these fracture dislocations. Our series includes 31 fracture dislocations, five extra-articular and 26 articular, 21 of which were at the base of the metacarpal, four at the hamate, and one involving both the hamate and the metacarpal.
