Is there a place for external fixation in humeral shaft fractures?

There is a good indication for unilateral axial dynamic external fixation in fractures of the humeral shaft when the fracture appears in the distal third or in cases of bilateral fractures. A non-union or a posttraumatic paralysis of the radial nerve may be indications for external fixation as well as fractures associated with multiple injuries. Further indications include osteitis, infected non-union and comminuted fracture. There is maximum protection of the soft tissue with this method of treatment. External fixation combines the advantages of conservative and operative treatment by influencing callus formation by dynamizing, distraction or compression. Minimizing soft tissue damage facilitates the decision for early exploration of the radial nerve in cases of palsy. A safer positioning technique of the distal screws of the fixator is described.     

New concept in external fixation

A new concept in external skeletal fixation is presented. A 3D unilateral system developed by Mitkovic has widely been investigated biomechanically in AO institute in Davos (Switzerland). Consists of three components only providing extremely simple application and dynamic fixation of bones and different joints. This simple external fixator functions as an accurate reduction device at the same time, minimizing need for fluoroscopy. Clinically this system has been applied to mere then 13 thousand patients in 43 clinics. This paper presents the results of its application for treatment of open fractures, war wounds with fractures and for comminuted and intraarticular closed fractures in the series of 597 patients. Overall average time for union time was 3.2 months. Overall success of fracture healing was 96.8% including open and closed fractures. Our study suggests that the use of this 3D unilateral system is suitable for routine use.

Biomechanical considerations in plate osteosynthesis: the effect of plate-to-bone compression with and without angular screw stability

OBJECTIVE: We compared the biomechanical stability of bone-plate constructs using a compression plate (CP), an internal fixator (IF), and a combination plate (CP/IF). METHODS: Standardized simulated shaft fractures with a segmental defect in composite bones (n=60) and intraarticular distal femur fractures with a comminuted supracondylar zone in fresh frozen cadaveric femurs (n=36) were stabilized by CP, IF, and CP/IF. Construct stiffness, plastic deformation, and fixation strength were measured under axial compression and torsion using a biaxial testing machine. RESULTS: The experimental results indicate for the distal femur fracture model that IF has less loss of reduction by plastic deformation under axial load compared to CP (IF 61% of CP). Under torsion, the CP showed significantly (P<0.05) decreased plastic deformation compared to the IF (CP 51% of IF). The combination (CP/IF) of the 2 fixation principles generally resulted in a higher load to failure under axial compression and torsion (145% failure load of CP and 118% of IF under axial compression, 88% of CP and 109% of IF under torsion). Results were similar between the 2 fracture models. CONCLUSIONS: Under compression, IF provides similar fixation in comminuted fractures and was better than the CP for avoiding loss of reduction, whereas under torsional loading, CP was more important for stiffness, plastic deformation, and load to failure than IF. However, combination (CP/IF) fixation seems advisable in intraarticular and extraarticular fractures of long bones with a metaphyseal comminution. These data may be utilized by surgeons to build a more specific treatment plan in patients with these fracture types.

The "S" Quattro in the management of fractures in the hand.

The "S" Quattro has shown its value in the management of displaced comminuted intra-articular phalangeal fracture dislocations. Since then the system has been used as a dynamic flexible external fixator in the treatment of five maluniting phalangeal fractures, five comminuted condylar and four severe compound fractures. These challenging fractures have been dealt with by easy operations, taking full advantage of the versatility of the "S" Quattro to achieve good results.
