Department of Orthopaedic Surgery, University of Alabama, Birmingham, AL.

Digital external fixation is often used for the management of complex injuries involving the proximal interphalangeal joint, including pilon fractures of the middle phalanx base and unstable fracture-dislocations. Several dynamic "homemade" constructs have been described which utilize only K-wires and rubber bands and allow early range of motion within the construct. Although these constructs are inexpensive and their application is fairly straightforward, their designs pose a few potential problems when the construct is stressed during rehabilitation efforts.

Treatments of unstable dorsal fracture dislocations of the proximal interphalangeal (PIP) joint are very challenging. The authors performed modified hemihamate arthroplasty for these injuries in 13 patients (13 fingers). Our surgical technique was unique in the point that we put volarly oblique osteotomy in the coronal plane at the recipient site to create an adequate reconstruction of the volar lip of the articular surface of the middle phalanx.

Aims: The aim of this study was to investigate whether clinical and radiological outcomes after intramedullary nailing of displaced fractures of the fifth metacarpal neck using a single thick Kirschner wire (K-wire) are noninferior to those of technically more demanding fixation with two thinner dual wires.

Patients And Methods: This was a multicentre, parallel group, randomized controlled noninferiority trial conducted at 12 tertiary trauma centres in Germany. A total of 290 patients with acute displaced fractures of the fifth metacarpal neck were randomized to either intramedullary single-wire (n = 146) or dual-wire fixation (n = 144). Read More

Orthopaedics, Hospital Kuala Lumpur, Kuala Lumpur, MYS.

Irreducible closed dorsal dislocation of distal interphalangeal (DIP) joint of the finger is a rare injury. The causes of irreducibility of the DIP joint are volar plate interposition, entrapment of flexor digitorum profundus tendon behind the head of middle phalanx, and buttonholing of the middle phalanx head through the volar plate or flexor tendon. Open reduction with a volar approach is recommended with the advantages of better wound healing, ease of releasing entrapped structures, and possibilities of a volar plate, collateral ligaments, and/or flexor tendon repair.

Background: Metacarpophalangeal (MCP) joint dislocations are the result of a hyperextension injury. Complex MCP joint dislocations-those that are irreducible to closed maneuvers and require surgical intervention-are considered uncommon, even in the pediatric population.

Locked thumb metacarpophalangeal joint caused by entrapment of the sesamoid bone is an uncommon entity. The intact volar plate, strong ligamentous attachment between the sesamoid bone and the joint, and altered axis of inserted muscle all contribute to failure of closed reduction.

Background: Dynamic external fixation is a useful treatment option for unstable fracture-dislocations of the proximal interphalangeal (PIP) joint, because it simultaneously reduces axial pressure load on the joint surface, maintains congruent joint reduction, and permits early joint motion. However, most current devices are large, hindering finger movement, and unstable. To address these problems, we developed a dynamic external finger fixator, named the Micro Ortho Fixator. Read More

Phalangeal fractures are common in all ages. Stable, extra-articular fractures can be treated non-operatively by closed reduction and buddy taping, while surgical fixation should be considered for unstable and displaced extra-articular fractures and most intra-articular fractures. The treatment should aim at early, active mobilisation in order to achieve the optimal functional outcome. Read More

The "jammed finger" is among the most common hand injuries and may include simple sprains, dislocations, fractures, and fracture-dislocations. In contrast, irreducible dislocations of the proximal interphalangeal joint are rare injuries. However, they must not be overlooked in the primary assessment, because persistent subluxation may lead to joint contracture, severely compromising hand function. Read More

Background: Pyrocarbon proximal interphalangeal joint arthroplasty provided patients with excellent pain relief and joint motion, however, overall implant complications have been very variable, with some good outcomes at short-medium-term follow-up and some bad outcomes at longer-term follow-up. Implant loosening with migration, dislocation and implant fracture were the main reported clinical complications. The aim of the present work was to test the hypothesis that the magnitude proximal interphalangeal joint cyclic loads in daily hand functions generates stress-strain behaviour which may be associated with a risk of pyrocarbon component loosening in the long-term.
