Open reduction and internal fixation as well as minimal-invasive techniques using minifixator systems may be employed. We use a minifixator, which allows pin-positioning even in small perarticular fragments eliminating the necessity of bridging joints. The anatomical basis, operative technique, and data of seven patients treated according to this method and results are presented. Range of motion according to the neutral-zero-method, tendon gliding, five-second-holding power, and force grip were equal compared to the uninjured contralateral side. The use of a minifixator to stabilize perarticular fractures of the first metacarpal includes the advantages of a minimal invasive procedure, respects the advantages of conservative fracture treatment, and permits secure fracture fixation after reduction.

The device has been used for one-stage correction with corticocancellous bone blocks as well as with hemicallotasis for correction of dorsal angulation. The technical application is described and the use of the external fixator defined. Fourteen patients were treated with radio-radial application, seven of those were corrected with callus distraction. The mechanical possibilities of the fixator allowed complete correction of the malunion.

The treatment of severely comminuted intra-articular fractures of the distal radius

Strategies in Trauma and Limb Reconstruction, 2006

The force of the impact and the position of the hand and carpal bone determine the pattern of articular fragmentation and their displacement and the amount and the extent of frequent concommitant ligament and carpal bone injury. The result of the osseous lesion in comminuted fractures was termed "pilon radiale", which emphasizes the amount of damage to the distal radius and the difficulties to be expected in restoring the articular congruity. Besides this the additional injury, either strain of disruption of the ligaments and the displacement of the carpus and/ or the triangular fibrocartilage complex will equally influence the functional outcome. This review will expand on the relevant anatomy, correct classification and diagnosis of the fracture, diagnostic tools and operative treatment options. Current treatment concepts are analysed with regard to actual literature using the tools of evidence based medicine criteria. A new classification of severely comminuted distal radius fractures is proposed using CT data of 250 complex intraarticular radius fractures. Finally a standardized treatment protocol using external fixation in combination with minimal invasive internal osteosynthesis is described.
