avulsion injury of the flexor digitorum profundus (fdp) with concomitant fracture of the distal phalanx dorsal base is uncommon. simultaneous avulsion fractures of the insertion of this tendon associated with rupture of the tendon from the bony fragment and combination with dorsal base fracture is very rare and also complicated. a 36- year- old man fell and injured his right little finger. fdp ...

Bennett's fracture is the retention of bone to which beak ligament attached, and dorsoradial proximal subluxation base metacarpal detached from this part. Key features are intra-articular fracture, oblique pattern, volar-dorsal fragment. The medial small piece remains in place maintains its relationship with second finger via volar ligament.

AbsractAll perilunate fracture-dislocations combine bone avulsions, ligament disruptionand fractures in different forms. The most frequent pattern is the dorsal transscaphoidperilunate fracture-dislocation. The reported risk of missed initial diagnosisin perilunate dislocations is as high as 20%. Concerning pathomechanics of theperilunate fracture-dislocation, it should be noted that most dorsa...

We report the cases of two men aged 35 and 33, who presented with similar injuries following a fall. They presented with pain isolated to the area of the index finger metacarpal base. Radiographs demonstrated an index metacarpal base fracture with a similar large ulnar-sided articular fragment extruded vol-arly. In the first patient the fragment was immediately adjacent to the remaining metacar...

The mechanism of injury in dorsal dislocations is usually PIP joint hyperextension combined with some degree of longitudinal compression, which frequently occurs in ball-handling sports if the tip of the digit is hit with the ball. In the majority of cases, dorsal dislocation produces a soft tissue or bone injury to the distal insertions of the three-dimensional ligament-box complex. The greate...

Stress is a proximal interphalangeal (PIP) joint model was analyzed by the two-dimensional and three-dimensional finite element methods (FEM) to study the onset mechanisms of the middle phalangeal base fracture. The structural shapes were obtained from sagittally sectioned specimens of the PIP joint for making FEM models. In those models, four different material properties were given correspond...
