Cannulated Screw

Product catalog summary
7.0mm Cannulated Screw Features & Benefits:
  • The full thread extends into the head profile, enhancing gripping ability, especially in osteoporotic bone, and facilitating easy removal.
  • A low-profile head minimizes soft tissue irritation.
  • The hemispherical head ensures optimal contact with washers or plates when screws are angled.
  • The cancellous thread profile with deep cutting threads and a large pitch increases resistance to pullout and accelerates screw insertion and removal.
  • The self-tapping screw tip reduces the need for pre-drilling and tapping.
  • Reverse cutting flutes aid in easy removal.
Specifications:
  • Standard hexagonal drive socket with a 4.5mm guide wire.
  • Available in short thread (16mm), medium thread (32mm), and full thread options.
  • Screw lengths range from 30mm to 120mm in 5mm increments.
  • 4.5mm shank diameter with a trocar tip threaded design.
Procedure for Percutaneous Pinning of Slipped Capital Femoral Epiphysis (SCFE):
  • SCFE is a common hip disorder in adolescents characterized by the displacement of the proximal femoral epiphysis.
  • Treatment aims to prevent further displacement and maintain hip function, with in situ screw epiphysiodesis recommended for stable and unstable SCFE.
Surgical Technique:
  1. Place Guide Wire: Insert the 2.8mm guide wire using a power drill to the desired depth.
  2. Countersink (optional): Use the cannulated countersink to create space for the screw head.
  3. Measure Length: Use the measuring device to determine the screw length, ensuring placement 5mm from the guide wire tip.
  4. Drill: Use the 4.5mm cannulated drill over the guide wire to the desired depth.
  5. Insert Screw: Select and insert the screw using the cannulated screwdriver shaft.
  6. Screw Removal: Use a non-cannulated hex driver or screw extractor if necessary.
Cleaning Tips:
  • Clean the cannulation in each instrument intraoperatively with a 2.8mm cleaning stylet and postoperatively with a cleaning brush and stylet to prevent debris accumulation.
Set Contents and Instruments:
  • Includes various screw lengths and instruments such as the Zimmer In-line ratchet, cannulated screwdriver shaft, and screw extractor.
Important Notes:
  • Devices are supplied non-sterile and must be cleaned and sterilized before use.
  • Implant components are single-use and not approved for attachment to the posterior elements of the spine.
  • This document is intended for medical professionals and does not replace individual patient examination and advice.

Percutaneous Pinning of Slipped Capital Femoral Epiphysis (SCFE) Slipped capital femoral epiphysis (SCFE), the most common hip disorder in adolescents, is defined as displacement of the proximal femoral epiphysis relative to the metaphysis. Displacement of the epiphysis is almost always posterior and inferior to the metaphysis. SCFE is categorized in terms of degree of slip as well as stable or unstable. Stability is defined clinically by an inability to bear weight. The goals of treatment include preventing further displacement and maintaining optimal hip function. In situ screw epiphysiodesis...

Surgical Technique Place Guide Wire Utilizing a power drill, insert the 2.8 guide wire (01-1071-012) through the 2.8mm drill guide (01-1071-018) stopping at the desired depth or location. After checking the placement of the guide wire with the image intensifier, remove the drill and prepare for the next step. (Figure 1) Countersink (optional) If countersinking the screw is desired, use the provided cannulated countersink (01-1071-015) over the top of the wire to create the necessary space needed to countersink the screw head. (Figure 2) Measure Length Place the provided measuring device (01-1071-017)...

Insert Screw After determining the correct screw length, select the screw type (fully or partially threaded). Insert the screw over the top of the guide wire using the provided cannulated screwdriver shaft (01-1071-006) in conjunction with either the power or the ratcheted screw driver handle. (Figure 5 & 6) Screw Removal Screw removal should be performed with the non-cannulated hex driver (01-1071-007). If damage has occurred to the screw and it becomes difficult to remove, a screw extractor (01-1071-020) should be used in place of the hex driver. The extractor is inserted into the cannulation...
