HAT-TRICK^◊ Lesser Toe Repair System

HAT-TRICK is a comprehensive, unique and versatile system offering surgeons three solutions for correcting lesser toe deformities. All 3 of these systems can work together or independently and are designed to provide improved patient outcomes with reproducible results.

Our three part solution

1.  HAT-TRICK MTP Joint Repair System

2.  HAT-TRICK PIP Fusion System

3.  HAT-TRICK Osteotomy Guide

HAT-TRICK MTP Joint Repair System 

• Addresses the plantar plate and the collateral ligaments
• Offers surgeons a less invasive and more anatomic solution

HAT-TRICK PIP Fusion System 

The only two piece PEEK design available offering:

• Controlled compression
• Improved visualization of the fusion site (PEEK Material) 
• Straight forward revision options

HAT-TRICK Osteotomy Guide

An alternative to the free hand osteotomy by offering:

• Enhanced control
• Improved precision
• Reproducible results designed to maintain the patient’s biomechanical axis.

 HAT-TRICK^◊ MTP Joint Repair

Challenge:

Metatarsophalangeal instability is commonly present with lesser toe deformities. Current standard of treatments often lead to complications like floating toes, loss of ROM, stiffness and residual pain.^{1, 2}

Solution:

The HAT-TRICK MTP Joint Repair System provides a complete repair of the lesser MTP joint that is less invasive and more anatomic than standard of care techniques. 

Bilateral

Controlled

• Allows for controlled tensioning of both plantar plate and collateral ligaments.

Less Invasive

• No required metatarsal osteotomy
• No screw fixation required
• No release of the plantar plate from the metatarsus

More Anatomic

• Anatomic reattachment of collateral ligaments
• Anatomic distal reattachment of plantar plate
• Maintains the biomechanical axis, which can be lost when performing a metatarsal osteotomy

Specialized Instruments

DART SUTURE PASSER^◊ - DART (Direct Anterior Repair Technique) SUTURE PASSER allows for access to plantar plate without an osteotomy

Offset Drill Guide - Short and long offset drill guides allow for drilling of two bone tunnels that do not intersect

Suture Tensioner and PEEK Interference Wires - Allows for controlled tensioning of the ligament repair

 HAT-TRICK^◊ PIP Fusion

10% – 46% of lesser toe patients are dissatisfied post-surgery¹

Challenge: 

K-wire fixations for Hammertoes often result in³

• Increased swelling, pain
• Pin-tract infection
• Delayed union
• Motion at arthrodesis site
• Painful removal

Solution:

The PIP Fusion System is a unique solution for surgeons treating patients suffering from lesser toe deformities by offering a two-piece all PEEK implant that provides controlled compression, improved visualization of the fusion site versus metal implants, MRI compatibility and straight forward revision options. This implant is available in multiple diameters with both 0° and 10° angulation options.

 HAT-TRICK^◊ Osteotomy Guide

Challenge:

Current metatarsal shortening techniques may move the center of rotation of the metatarsal head plantar off the biomechanical axis.

Solution:

The HAT-TRICK Metatarsal Osteotomy Guide is designed to provide surgeons with an alternative to the free hand osteotomy by offering enhanced control, improved precision and reproducible results that work to maintain the biomechanical axis of the metatarsal. ⁵

Instrumentation

Controlled:  K-wire provision fixation holds guide in place

Precise:  Multiple spacer options allow for precise length of shortening

Reproducible: Tab in the MTP joint space allows the surgeon to reproducibly line up the osteotomy
