Product catalog summary
Overview
This document provides detailed information on the BSS screws manufactured by Mikai S.p.A., designed for various orthopedic applications, particularly in hand, wrist, and elbow surgeries. The screws are made from medical-grade titanium alloy and are supplied sterile, ready for use.

Indications
The screws are indicated for use in a variety of fractures and fusions, including:
  • Radio-carpal and four-corner fusions
  • Radial and ulnar styloid fractures
  • Scaphoid fractures/nonunions
  • Carpal bone fractures
  • Transverse fractures of the phalanges and metacarpals
  • PIP and MCP fusions
  • Intra-articular fractures of the phalanges and metacarpals
  • Capitellum, distal humerus, radial head, epicondyle, coronoid, and olecranon fractures

Features
The BSS screws feature a tapered head for maintaining interfragmentary compression, are self-drilling for easy insertion, and are available in two diameters (Ø 2.5 mm and Ø 3.0 mm) with a range of lengths (10-40 mm). They allow for controlled compression, avoiding loss of reduction and over-compression in fracture fixation.

Clinical Benefits
The screws provide excellent compression capacity, with a compression index of 0.15 mm per screwdriver revolution, achieving a total compression of 0.6 mm when fully inserted.

Clinical Cases
Three clinical cases are presented, demonstrating the use of BSS screws in various fracture fixations and fusions, highlighting successful outcomes in different patient scenarios.

Ordering Information
The document lists various BSS screw models with specific dimensions and thread lengths, along with associated instruments such as K-wires, screwdrivers, and drill guides.

Sterilization
BSS screws are supplied sterile, and it is recommended that instruments be sterilized in an autoclave using saturated steam at 134°C for 10 minutes.

Contact Information
Details for Mikai S.p.A.'s headquarters and manufacturing facility are provided for further inquiries.
