Bio-Compression Screws are versatile and may be used to treat a broad range of indications in both lower and upper extremities. Designed with a stepped pitch and taper, this screw draws two fragments together using straightforward instrumentation for drilling and tapping. Made of solid enhanced PLLA material, the BCS absorbs over time without losing strength during insertion or through the critical phases of healing. With Bio-Compression Screw technology, zero-head-prominence above the cortex and zero image on x-ray is possible, creating a very natural repair. Offered in two families, 3 mm and 3.5 mm, the 3 mm screws range in two millimeter lengths from 16–26 mm. The 3.5 mm screws are fully cannulated and come in two millimeter lengths from 16–32 mm with a variable proximal diameter. Applications in the foot and ankle include OCDs, fractures, osteotomies and arthrodesis of the tarsals, metatarsals and phalanges. From bunion correction to trauma management, the Bio-Compression Screw provides excellent compression and holding power maintained throughout the normal healing period. For lower extremity surgery, the Bio-Compression Screw may be inserted either percutaneously or in an open procedure. Accurate placement of the screw can be ensured by using the cannulated instrumentation in the set.

The 2.7 mm Bio-Compression Screw eliminates the challenges of metal screw removal, soft tissue impingement, and unwelcome image scatter. For fracture and osteotomy fixation in periarticular applications, this screw offers interfragmentary compression and a headless profile to promote healing. Produced from solid enhanced PLLA and designed for excellent thread-to-bone contact, the Bio-Compression Screw provides excellent strength during insertion and through healing. Using a stepped thread pitch and a taper, this screw draws two fragments together without the need to overdrill/lag the proximal bone fragment. And since the Bio-Compression Screw is headless and absorbable, it offers zero prominence above the cortex and is not visible on x-ray. This is as close to a natural repair as possible. A simple, low cost instrumentation set ensures proper drill depth and tapping with no guesswork.

Bio-Compression Technique

A chevron osteotomy is the most common technique used to correct mild to moderate bunion deformities. Traditionally, this procedure has been performed through an open approach. However, since the advent of minimally invasive surgery (MIS), surgeons now have the option to perform a chevron osteotomy through small percutaneous incisions. Following the osteotomy, the capital fragment is shifted laterally and fixated with either Compression FT screws for the MIS approach or Compression PT screws for the traditional open approach.

Chevron Osteotomy

Navicular fractures can be treated with 3.0 mm BioCompression or 3.0 mm Cannulated Screws.

Navicular Fracture Repair

The bioabsorbable PLLA Chondral Dart has a unique, double reversed barbed design to facilitate superior fixation and compression of osteochondral flap tears up to 2 cm in diameter. The 18 mm long, 1.3 mm diameter Chondral Dart provides secure fixation under the hyaline cartilage surface to eliminate contact with sensitive articulating surfaces. 
 
For larger lesions, the Bio-Compression Screw may be used to fixate OCD lesions securely while eliminating the challenges of metal screw removal, soft tissue impingement, and unwelcome image scatter. Produced from solid enhanced PLLA and designed for excellent thread-to-bone contact, the Bio-Compression Screw provides excellent strength during insertion and through healing.
