2 Hallux Limitus and Hallux Rigidus Hallux limitus is a progressive condition where the hallux, or big toe, has a limited or decreased range of dorsiflexion. If left untreated, pain and pressure placed on the joint while walking may cause arthritis, a dorsal bunion, and possible total loss of motion or hallux rigidus (the most severe stage of hallux limitus.) 1, 2 Hallux limitus may develop as a result of several contributing factors: Gradual deterioration of the joint due to age; poor footwear; obesity; a long elevated 1st metatarsal; trauma to the first metatarsal; rheumatoid arthritis; continuous cartilage wear and tear and/or fallen arches. Symptoms may result from a change in joint mechanics, or from an osteophyte or bunion formation particularly on the dorsal aspect of the metatarsal head. Pain or impingement of the dorsal osteophytes, inflammation, or shoe related pressure is also possible, along with motion pain from the articulating cartilage surface irregularity. 3, 4 Hallux rigidus symptoms develop in the last stage of hallux limitus. In addition to early stage symptoms, patients with hallux rigidus may also experience pain and stiffness in the big toe from degenerative arthritis and limited-to-absent range of motion. Degenerative arthritis is a type of wear and tear that causes a loss of cartilage in one or more joints and may change the way the foot functions. 1, 2, 3, 6 Pain is most associated with physical activities and may increase with running or jumping. Knee, hip, and/or lower back pain may develop as a result of a patient changing their stride to reduce pressure and discomfort. Common tests to evaluate hallux limitus and hallux rigidus are foot examinations, and the identification of bone spurs using diagnostic imaging. Radiographic findings could show flattening of the metatarsal head, narrowed joint space, location and size of bone spurs, as well as the degree of degeneration in the joint space. Range of motion is tested by bending the toe in an upward and then downward position to evaluate pain. 4, 7 Several grading levels or stages have been developed to describe and treat hallux limitus and hallux rigidus. Determining the treatment of each condition is based upon the grade or stage and health of the patient. If diagnosed and treated early, non-surgical methods such as limiting motion with a rocker type shoe, correct 4, 8, 9 shoe wear to eliminate pressure, orthotics, physical therapy, and/or cortisone shots may be an option.

3 Discussions on Staging Many staging systems for hallux limitus and hallux rigidus have been proposed, each with their own recommendations for procedures of diagnosis and treatment options. Because there is no universal agreement on a single staging system for the disease state, Integra LifeSciences Corporation has created this document to fairly and accurately represent a sample of the many staging systems available, in order to accommodate as many foot and ankle specialists as possible. The article, What s new in Foot and Ankle Surgery by Randall C. Marx, MD and Mark S. Mizel, MD, in the June 2009 issue of The Journal of Bone and Joint Surgery is effective in describing the current hallux limitus and hallux rigidus staging issue: Hallux rigidus is one of the most common causes of forefoot pain, yet a formal classification system has yet to be devised. Beeson et al. performed a review of the literature in order to determine if a gold standard classification system for hallux rigidus exists 27. Eighteen formal hallux rigidus classification systems that were based on radiographic appearance and/ or clinical findings were identified; however, different criteria and methods were used in their construction. Additionally, no classification systems had been rigorously tested for reliability or validity, and all were based mainly on clinical experience rather than formal research. That study underscores the need to develop a classification system based on properly constructed prospectively designed studies for a disease as common as hallux rigidus. 15 The staging systems contained herein were interpreted as accurately as possible from published literature from their respective investigators. All references used in the making of this document are available in the bibliography, on the back page. In cases where hallux limitus has significantly progressed, or in circumstances where non-surgical applications have failed, surgical treatment may be required to correct the damage. Integra LifeSciences Corporation offers innovative and comprehensive products, designed for the surgical procedures associated with the treatment of hallux limitus.

4 FEATURED SOLUTIONS Bold Compression Screw QWIX Fixation Screw Osteotomy Solutions The 1st metatarsal is cut to change the alignment of the bone in an attempt to correct the hallux limitus. Various osteotomies are performed for this clinical condition and Integra LifeSciences Corporation offers multiple solutions for them. Surgeon Investigator Osteotomy Coughlin 10 Hanft Et Al 11 Grade I, Grade II Hattrup + Johnson 12 Kravitz Et Al 13 Stage II, Stage III A, Stage III B Roukis 14 Stage III Keisermann 5 Stage III BOLD Compression Screw The BOLD Compression Screw is a totally intra-osseous implant with a large range of sizes and K-wire guided drilling and screwing. This self-tapping titanium alloy screw allows for true and controlled compression in forefoot osteotomies. The BOLD screw is indicated for fixation of bone fracture or for bone reconstruction including: - Fixation of small bone fragments, in long bones or small bone fractures - Arthrodesis in hand or foot surgery - Mono or Bi-Cortical osteomies in the hand or foot - Distal or proximal metatarsal or metacarpal osteotomies - Fixation of osteotomies for Hallux Valgus treatment (such as Scarf, Chevron, etc.) QWIX Fixation Screw Sizes 3.0 & 4.3mm The QWIX Fixation Screws are designed to provide speed and precision for challenging surgical situations. This self-drilling, self-tapping QWIX 3.0 and 4.3 are designed with self-drilling flutes, but bone hardness can greatly vary by patient and anatomic area.* * The surgeon is responsible for assessing this hardness before using the self-drilling feature of the QWIX screws. Pre-drilling is advisable for dense or hard bone. Insertion features variable lags to ensure compression across the osteotomy site. The QWIX screw is indicated for fixation of bone fractures or for bone reconstruction including: - Fixation of small bone fragments, in long bones or small bone fractures - Mono or Bi-Cortical osteotomies in the hand or foot - Hallux Valgus treatment - Fractures management in the hand or foot - Arthrodesis in hand or foot surgery

5 FEATURED SOLUTIONS K2 Hemi Toe Implant System KGTI Kinetik Great Toe Implant System Arthroplasty Solutions Arthroplasties are surgeries that surgically repair a joint by replacing the articular surface with a new material, while removing the offending bone surface. Integra LifeSciences Corporation offers solutions for both partial and full arthroplasties of the first metatarsophalangeal joint.
