In conclusion, each of these methods have been proven to be effective in selected patients. None of these methods, however, can be used in all patients. They must be carefully evaluated for use in young patients where anatomic alignment is essential to avoid impairment of function with loss of grip strength and the possibility of developing post-traumatic arthritis. If any of these methods is used, ideal cases would be those with nonarticular fractures, with minimal displacement and minimal bone loss, and some assurance that the fracture will remain stable during treatment. The techniques have been proven to be effective. If, however, fracture reduction is lost with any of these techniques, one must reassess the fracture, especially in the young, and be more aggressive in restoring and maintaining alignment until healing has occurred. Orthopaedic Knowledge Update 3, published in 1990, relates, "Depending on comminution, fixation may be best achieved with plate, screws, Kirschner wires, external fixation or some combination of these." It goes on to state, "In young adults particularly, accurate reduction of the articular surface appears critical to achievement of a good result after a Colles' fracture."
In the conservative treatment of distal radial fractures the main problem is redislocation due to instability. We evaluated the three classification methods most often used to find out how well the different groups correspond to instability and severity of fractures-thus what their prognostic value is in the probable recovery time. Based on an analysis of 633 cases, we found that neither the most often used Frykman nor the AO and older classifications have any practical significance in this respect.

The article describes a case of radius/ulna fracture in a lynx, Felix (Lynx) lynx. Osteosynthesis was performed using a combination of a dog bone plate at ulna and medullary pins in radius. The special anatomical features of the radius and ulna of the lynx determined the choice of surgical technique.
A randomised prospective study was carried out to compare non-bridging external fixation using a small A0 external fixator with percutaneous Kirschner wire fixation and plaster in the treatment of distal radial fractures (A2/A3 in the A0 classification). The study involved 40 patients, 20 in each group. The advantages of the non-bridging fixation are: (1) early functional therapy of the wrist, (2) simplified reduction of the fracture, and (3) considerable less restriction of wrist mobility in day-to-day situations. Although the final examination 6 months after treatment showed almost identical functional results, the patients treated with the external fixator benefited from the fact that use of the wrist was virtually free throughout the entire treatment period.

From 1992 to 1995 126 patients were treated with percutaneous wire pinning. Sixty-one patients were treated by Kapandji's technique and 65 patients were treated conventionally. Forty-nine patients were examined by 3 different scores (Cooney, Castaing, Stewart). The analysis of the scores showed no differences between the Kapandji technique and the conventional method. Functional and radiological results showed no correlation. Furthermore we found out that the results depend on the score. We conclude that the Kapandji technique shows no benefit in comparison to the conventional method. Functional and radiological results are not divisible: a conclusion from X-ray to function and vice versa is not allowed. A comparison of results is senseless if someone does not use the same score.
