“…Bone mineral density (BMD) was measured after operative ankle fracture treatment with bioabsorbable SR-PLLA or metallic screws [3]. The average BMD value in the distal tibia was 18% lower after metallic screw fixation compared to the non-operated ankle as early as after 1.4 years; after SR-PLLA screw fixation the BMD value was only 6.4% lower than in the non-operated ankle after 3.9 years.…”

This is an analysis from one hospital of the first 1043 operations where pure self-reinforced poly-Llactide (SR-PLLA) implants have been used alone. The operations were performed between 1988 and 1999 and included 407 orthopaedic patients and 636 trauma patients. There was a total of 107 complications. There were 21 infections but no sinus formation. Failure of fixation was seen in 46 patients. In 936 operations the healing was uneventful. IntroductionBioabsorbable fixation devices have been used clinically in bone fixation for 17 years. Presently, bioabsorbable implants are used with several indications in orthopaedics, sports medicine, and trauma surgery. This study is an analysis of the first 1043 operations where pure poly-L-lactide (SR-PLLA) implants have been used alone without any other implants. The study aims to clear up possible difficulties related to the use of bioabsorbable fixation devices in orthopaedics and traumatology. Material and methodsAll operations were performed at the Department of Orthopaedics and Traumatology, Helsinki University Central Hospital, during the years 1988-1999. The indication for operation was orthopaedic disorder (e.g. arthrodesis in rheumatoid arthritis, hallux valgus, and instability of the shoulder) in 407 patients, and trauma (mainly fractures and ligament ruptures) in 636 patients. The mean age was 43 years for orthopaedic patients and 37.7 years for trauma patients. In the orthopaedic series there were 294 women (72.2%) and in the trauma series 278 women (43.7%). All complications were counted, as were small variations from normal without any need for special treatment. Each complication was signed up separately, e.g. failure of fixation causing infection and further non-union were counted as three complications. ResultsThe results are summarised in Table 1. The average operation time in the orthopaedic series was 63 min and in the trauma series 48 min. A total of 55 complications (13.5%) was seen in the orthopaedic series (Table 2) and 52 (8.2%) in the trauma series (Table 3). The overall complication rate was 107/1043 (10.3%). Infection was seen in 13 orthopaedic and eight trauma patients (2%). Failure of fixation was found in 20 (4.9%) patients in the orthopaedic series and 26 (4.1%) in the trauma series. There were no sinus formations. No fluid accumulation was seen in orthopaedic patients whereas three trauma patients (0.5%) had fluid accumulation. Deep venous thrombosis was present in eight patients -three in the orthopaedic series and five in the trauma series. The postoperative healing was uneventful in 936 (89.7%) Statement on conflict of interest: No benefits in any form have been received or will be received from a commercial party related directly or indirectly to the subject of this article

“…As bioabsorbable implants degrade gradually there is no need to remove the implants. Moreover, the economic impact of bioabsorbable fixation devices seems to be more favourable than that of metallic implants in the operative treatment of ankle fractures when all expenses are considered [4].…”

“…Implantate aus biologisch abbaubaren Kunststoffen wie Polydioxanon (PDS), Polylaktid (PLA) und Polyglykolid (PGA) haben bereits Eingang in die klinische Praxis gefunden [1,2,3,4,5,6,10,11,13,14,15,19,20,24,27,28,31]. Polyglykolide zeigen eine große initiale Festigkeit aber rapide Festigkeitsverluste nach der Implantation sowie eine hohe Rate an Fremdkörperreaktionen bei der klinischen Anwendung [15,18,22,32].…”

For biomechanical evaluation of cortical bone as a potential source for internal fixation devices, pins of 2 and 3 mm in diameter were made from fresh human femora and subjected to bending loads. Some of the pins were tested without further treatment; others were defatted and dried in acetone solution. Of the acetone-treated pins, some were autoclaved either at 121 degrees C for 20 min or at 134 degrees C for 8 min. Acetone treatment of the pins caused a 5.5% increase in bending strength (p < or = 0.05) and a 6.6% increase in the elastic modulus (p < or = 0.05). The mean bending strength of the acetone-treated pins was 257 +/- 52 N/mm2 and the mean elastic modulus was 18,346 +/- 1292 N/mm2. Autoclaving of the pins at the lower temperature for a longer time led to a decrease in the bending strength of up to 16% and at the higher temperature for a shorter time to a decrease of up to 41%. To compare the strengths of the cortical and synthetic pins, 2-mm Biofix pins were also tested. The Biofix pins showed a 25% higher bending strength than the acetone-treated pins but a 12.5% lower elastic modulus. It should be noted that in animal studies the synthetic Biofix pins showed a 20% loss of strength within 2 days after implantation in situ.

“…Revision surgery hence increases the medical costs as well as the health risks for patients. The development of absorbable orthopaedic devices aims to lower these medical expenses, and evidence has shown that total medical expenses were lower when using absorbable (polymer) orthopaedic devices compared with traditional non-absorbable metallic devices [3][4][5][6][7].…”

Biodegradable metals have attracted interest for implant applications because of the potential to eliminate secondary surgeries. Magnesium-based (Mg-based) alloys are potential candidates. The purpose of this study was to evaluate the in vitro and in vivo degradation performances of two custom-made magnesium-based alloys and to determine whether they are sustainable for further investigation. The performances of Magnesium-Zinc-Manganese (MgZn-Mn) alloys at 5% and 1% zinc levels were compared using a mechanical test, hydrogen evolution test, cell viability (MTT) test, and a short term mice subcutaneous implantation. The results showed that the corrosion resistance of the Mg was improved by alloying. While Mg-5Zn-1Mn was more corrodible compared with Mg-1Zn-1Mn, neither of the alloys presented any adverse effects preliminarily and both were suitable for long-term testing for biomedical applications.
