Case: Fracture of Patella

18 years old, normal weight male had fracture of patella occurred while playing badminton due to subluxation of the patella. A dislocated 26 x 15 mm fracture was found at the medial side of the patella and loose osteochondral fragments were found around the main fracture.

The main fragment was fixed using one ActivaScrew™ 4.5 mm x 45 mm fully threaded. A loose osteochondral fragment was fixed using two ActivaPin™ 2.0 mm x 30 mm.

As a postoperative care a functional brace was applied. Partial weight bearing was allowed at 3 weeks and full weight bearing at 6 weeks.

Bone healing took place and the patient was able to return to normal sport activities 6 weeks postoperatively.

ActivaScrew™ 4.5 mm is well suitable for fixation of large patellar fractures. The ActivaPin™ 2.0 mm is a practical tool in fixing small osteochondral fragments.

Case: Fixation of Malleolar Fracture Using ActivaScrews™

 

Patient was an 18 years old normal weight sports active male, with high energy snowboarding injury. Preoperative X-ray revealed 4 mm dislocated Weber B -

type lateral malleolus fracture with rotational mal position. The fracture was fixed through the lateral incision with two fully threaded ActivaScrew™ 4.5 x 50 mm bioabsorbable screws. Heads of the both screws were cut off using an oscillating saw.

As a postoperative immobilization a functional brace was applied. Partial weight-bearing was allowed at 3 weeks and full weight bearing at 6 weeks.

Functional result of the operation was excellent. ActivaScrew™ 4.5 mm is well suitable for fixation of malleolar fractures. The screws can be cut to sufficient length with an oscillating saw intraoperatively.

Case: Fixation of Malleolar Fracture Using ActivaPins™

 

Patient was 58 years old normal weight female, with Weber A -type lateral malleolar fracture. Primary treatment was done conservatively with 6 weeks plaster cast immobilization. Pain persisted and clinical examination suggested a nonunion of the fracture.

Two ActivaPins™ 20 mm x 30 mm were used in angle to create rigid stability and compression to the fragment line. Both implants were fully inserted and proximal heads of the pins were sunk 1 mm under the cortical level. During the operation good compression of the

fracture was achieved due to grooved pin surface. As a postoperative care a functional brace was applied. Full weight bearing was allowed after 6 weeks. After failed conventional treatment, the Weber A -type malleolar fracture was successfully treated with two ActivaPins™.
