[Orthopaedic applications for biodegradable and absorbable internal fixation of fractures].

OBJECTIVE: To illustrate the effect and complication of orthopedic applications for biodegradable and absorbable internal fixation of fractures, and to indicate the existent problem and research aspect currently. METHODS: The recent literatures on orthopedic applications and study of biodegradable and absorbable internal fixation for fractures were reviewed. The effect of biodegradable materials on bone healing was summarized. RESULTS: It is good for the stability of fracture fixation and result of treatment. The biodegradable and absorbable internal fixation fractures had no adverse effect on bone healing. CONCLUSION: There will be more widespread application for biodegradable and absorbable materials in orthopedics, but the intensive research should be carried out to prevent its complication.

Internal plate fixation of fractures: short history and recent developments.

Metal plates for internal fixation of fractures have been used for more than 100 years. Although initial shortcomings such as corrosion and insufficient strength have been overcome, more recent designs have not solved all problems. Further research is needed to develop a plate that accelerates fracture healing while not interfering with bone physiology. The introduction of rigid plates had by far the greatest impact on plate fixation of fractures. However, it led to cortical porosis, delayed bridging, and refractures after plate removal. These unwarranted effects were said to be caused by bone-plate contact interfering with cortical perfusion. Consequently, further plate modifications aimed to reduce this contact area to minimize necrosis and subsequent porosis. The advocates of limited-contact plates have not published measurements of the contact area or proof of the temporary nature of the porosis. Moreover, clinical studies of newer plate types have failed to show a superior outcome. Histomor-phometric measurements of the cortex showed no difference in the extent of necrosis under plates having different contact areas. Necrosis was predominant in the periosteal cortical half, whereas porosis occurred mostly in the endosteal cortical half. No positive correlation was found between either. The scientific evidence to date strongly suggests that bone loss is caused by stress shielding and not interference with cortical perfusion secondary to bone-plate contact. Consequently, an axially compressible plate (ACP) incorporating polylactide (PLA) inserts press-fit around screw holes was designed. The bioresorbable inserts should allow for (1) increased micromotion in the axial plane to promote healing during the union phase and (2) gradual degradation over time to decrease stress shielding during the remodeling phase. Results of ongoing experimental results are encouraging. Only plates allowing dynamic compression in the axial plane can lead to a revolution in fracture fixation.

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.
