Bioretec’s ActivaPin™ bioresorbable implant provided excellent clinical outcome in the treatment of pediatric wrist fractures

A study published in a well-known peer reviewed scientific journal, ‘BMC Musculoskeletal Disorders’, confirmed the significant benefits of Bioretec’s bioresorbable ActivaPin™ implants for pediatric patients in the treatment of severely displaced distal radius and forearm fractures. The ActivaPin™ has been in the market since 2008, and the product is currently used in over 30 countries.

The results of the retrospective multicenter study indicate that patients treated with bioresorbable ActivaPin™ had significantly lower levels of complications than those treated with traditional non-biodegradable metallic Kirschner-wires (K-wires) and no second surgical intervention was required.

“The results of the study are very encouraging. The novel surgical technique leads to less complications and also offers major advantages to surgeons. The benefits of ActivaPin™ were most pronounced in the first six weeks after surgery: the number of outpatient visits were reduced, and children’s sense of comfort was increased. In addition, avoiding second surgical intervention results in significant cost savings. And most importantly, children can return to their normal everyday life and activities faster,”

In children, distal radius fractures are common, and severely displaced fractures may require surgical intervention. Percutaneous K-wire osteosynthesis followed by immobilisation is the current best practise surgical approach. Non-biodegradable metal implants, on the other hand, frequently necessitate surgical removal, which might result in further difficulties. The ActivaPin™ implant is made of a bioresorbable polymer (PLGA) that dissolves in the body in around two years.

A total of 94 individuals were examined in three paediatric trauma centres for the study. Patients with substantially displaced distal forearm radial fractures underwent procedures and were treated with either K-wire or bioresorbable ActivaPin™.

The company stated, ‘The study groups were examined for the number of minor and major complications as well as the need for repeated interventions. The complication rate of the ActivaPin™ group was significantly lower than of K-wire group, and there were no major complications associated with ActivaPin™. In addition, no signs of growth disturbance were found in any of the children after long term 18 months follow-up of the injury.’
