Bipolar fixation of fractures of the distal end of the radius

Uso do fixador externo no tratamento das fraturas cominutivas da extremidade distal do rádio

Foi realizado um estudo combinado retrospectivo e de reavaliação de uma população original de 60 pacientes, somando 64 fraturas da extremidade distal do rádio submetidas ao tratamento pelo método da fixação externa, num período de dez anos (janeiro 86 a janeiro 96). Foram estudados retrospectivamente 46 pacientes com 50 punhos. Compareceram para reavaliação 32 pacientes, totalizando 35 punhos. No estudo retrospectivo, foi realizada a medida dos parâmetros ângulo radial, ângulo volar, comprimento relativo do rádio, ângulo escafo-semilunar, ângulo luno-capitato e sinal do anel no escafóide, nas radiografias finais do seguimento dos pacientes. Na reavaliação, além dos parâmetros clínicos e funcionais, a medida da diastase escafo-semilunar em incidência radiográfica especial foi adicionada aos parâmetros radiográficos previamente estudados. Os resultados mostraram que o método da fixação externa restabelece a anatomia da extremidade distal do rádio, propiciando bons resultados clínicos e funcionais na maior parte dos pacientes, com baixo índice de complicações.

Bipolar fixation of fractures of the distal end of the radius: a comparative study

This paper reports a prospective study of the treatment of Colles' fractures, either by bipolar fixation or a forearm cast. Bipolar fixation reduced the degree of secondary displacement and no patient required a repeat manipulation. The functional results at 6 months, as assessed by the Scheck system, showed a strong trend in favour of bipolar fixation, but did not reach 95 per cent confidence limits. The technique of bipolar fixation proved to be safe and suitable for use in a busy district general hospital, without the necessity of elaborate equipment.

Comminuted Colles' fractures treated with external fixation

In a prospective series of 75 patients the results of early external fixation of comminuted intraarticular Colles' fractures were studied. Comparison was made to a control group of 32 patients treated with plaster cast fixation. The groups were equal with regard to age, sex and fracture type. The treatment consisted of reduction in general anaesthesia or arm block followed by the application of a small external fixation device. The fixation lasted for five weeks after which the patients were allowed free exercises. For evaluation at the one year follow up the following variables were used: Radiographic appearance. Healing in of the styloid process of the ulna. Subjective evaluation according to the Lidström score. Objective evaluation including range of motion and grip strength. In all follow up variables the treatment group was significantly better than the control group. The prognosis of conservatively treated comminuted intraarticular Colles' fractures is poor. The results of after external fixation are, however, very encouraging and the method can be recommended.

Bipolar fixation of fractures of the distal radius: preliminary results

Twenty-eight unstable distal fractures of the radius have been treated with pins incorporated into a forearm plaster. The wrist is maintained in a neutral position permitting early use of the hand. Secondary displacement has been decreased. It is a safe and effective method of treating unstable distal fractures of the radius suitable for regular use in a busy district general hospital without the need of expensive specialized equipment.

Severely comminuted distal radial fracture as an unsolved problem: complications associated with external fixation and pins and plaster techniques

Seventy-six patients with severely comminuted distal radial fractures were treated at two institutions, of which the overwhelming majority were Frykman class VIII. Fifteen fractures were open. Thirty patients were seen at the University Hospital; 17 had pins and plaster and 13 had external fixation. Forty-six patients were seen at Kaiser Hospital; all had pins and plaster treatment. The complication rate for those with pins and plaster at the University Hospital was 53%; the complication for external fixation rate was 62%. The affiliated-hospital complication rate was 52%. All patients with ipsilateral forearm shaft and carpal fractures developed a nonunion of the carpal fracture. Few patients maintained anatomic reduction, and many had significant intra-articular malalignment. External fixation with threaded half pins did not obviate pin problems in our series. These methods may help manage severely comminuted distal radial fractures, but complications should be anticipated and alternative treatment considered, especially when ipsilateral carpal or forearm shaft fractures are present.
