Foot and ankle surgeons have no shortage of choices when it comes to selecting instruments for surgical procedures. Our surgical team has found success in using the Koby line of instruments (OsteoMed) for the treatment of various conditions.
For the last four years, surgeons have found success using Koby instruments for three procedures commonly performed in the foot and ankle. Koby instruments are designed to perform the partial plantar fasciotomy for heel spur syndrome, intermetatarsal ligament decompression of neuroma and release of the gastrocnemius tendon in heel cord lengthening.1
The instruments consist of a separate set of tools in a sterilization tray that includes the KobyGard flex tip instrument, ligament and fascial separators, and a tissue locator (fascial elevator). A single-use, sterile blade is wrapped separately.
The instruments were originally designed and manufactured by Koby Surgical in 2001. The Koby Isogard was marketed as an alternative to the endoscopic plantar fasciotomy (EPF). OsteoMed took over the manufacturing and marketing of the system in 2004 and the system is now known as the KobyGard.
Prior to using the Koby instruments, we used the Instratek Endotrac system and performed EPFs.2 Their Edintrak instruments were also used for release of the intermetatarsal ligament. We had also devised a technique to use the EPF instruments to perform an arthroscopic gastroc recession. Unfortunately, when we would probe the surgical site after performing a procedure, we could usually feel an additional fascia, ligament or tendon.
To solve this problem, we would reinsert the triangle blade directly into the site and further release the soft tissue. However, this additional percutaneous release occasionally led to an over-releasing of the plantar fascia and damage to the sural or plantar intermetatarsal nerve.
Underscoring The System’s Ease Of Use
Using the KobyGard system enables surgeons to address these problems. If you determine that a structure has not been adequately released after probing with the fascial elevator, one can easily reinsert the KobyGard flex tip instrument and further release the tissue.
The Koby system was originally designed around carpal tunnel instruments. One would place the KobyGard instrument around the tissue to be released and its tines protect the tissue. At its distal end is a stop that prevents tissue from entering the end of the instrument. Inside the tines is a groove for the blade to travel. The blades are designed to be long enough to cut the medial and lateral bands of the plantar fascia.
Working with Koby Surgical several years ago, we designed a longer Koby instrument that replaced the Instratek EPF instruments for use in gastroc recessions. The Koby instrument uses the same blade but the additional length makes it easier to encompass the gastroc tendon.
