Conservative Heel Pain Treatment

Conservative Heel Pain Treatment Brian K. Bailey, DPM, MS Podiatric Physician & Surgeon Ashland, KY (606) 324-FOOT (3668) http://www.pandoracats.com/BMSPC/BMS PCmain.html Plantar Fasciitis Plantar Fasciitis Inflammation and pain along the plantar fascia - the tissue band that supports the arch on the bottom of the foot Usually on the bottom of the heel at the point where the plantar Plantar fascia attaches to the heel bone Becomes chronic in 5-10% of all Fasciitis patients Is not necessarily associated with a heel spur Over 90% resolve with conservative treatment Plantar Fasciitis Symptoms Pain on standing, especially after periods of inactivity or sleep Pain subsides, returns with activity Pain related to footwear – can be worse in flat shoes with no support Radiating pain to the arch and/or toes In later stages, pain may persist/progress throughout the day Pain varies in character: dull aching, “bruised” feeling. Burning or tingling, numbness, or sharp pain, may indicate local nerve irritation Other Potential Causes of Heel Pain Calcaneal Stress apophysitis Arthritis Gout fracture (children) Achilles Pinched tendon Bone cyst nerve/Nerve Neuropathy problems entrapment Low back or disk problems What is the diagnosis? Also called “adult- acquired flat foot” and "progressive flatfoot," PTTD occurs when inflammation or damage to the posterior Posterior tibial tendon reduces its ability to support the arch. Tibial This often results in flattening of the foot, meaning the entire foot Tendon touches the floor when you’re standing. Although Dysfunction PTTD usually occurs in only one foot, some people may develop the condition in both feet. It typically will continue to get worse, particularly if it is not treated early. Posterior Tibial Tendon Dysfunction Symptoms The symptoms of PTTD may include pain, swelling, a flattening of the arch, and an inward rolling of the ankle. When PTTD initially develops, there is pain on the inside of the foot and ankle (along the course of the tendon). In addition, the area may be red, warm, and swollen. As the arch begins to flatten, there may still be pain on the inside of the foot and ankle. But at this point, the foot and toes begin to turn outward, and the ankle rolls inward. As PTTD becomes more advanced, the arch flattens even more and the pain often shifts to the outside of the foot, below the ankle. The tendon has deteriorated considerably, and arthritis often develops in the foot. In more severe cases, arthritis may also develop in the ankle. Posterior Tibial Tendon Dysfunction Diagnostic feature is the patient’s inability or difficulty in performing a unilateral heel raise. Weakness inverting their foot Posterior Tibial Tendon Dysfunction Treatment Mild PTTD is treated similarly to plantar fasciitis Moderate to severe PTTD requires bracing Start with a Swedo brace and schedule for casting for an AFO Baxter’s nerve entrapment The first branch of the lateral plantar nerve becomes entrapped in the medial heel With entrapment, the pain is more localized, it is pressure sensitive, Baxter’s and gets worse with activity rather nerve than better. Usually responds well to ultrasound entrapment guided corticosteroid injections Injections only treat the symptoms, so it is essential to treat the causative underlying biomechanical abnormalities Tarsal Tunnel Syndrome Tarsal Tunnel Syndrome Entrapment of posterior tibial nerve The most common cause is repetitive pronation/supination Pronation causes narrowing of the tarsal tunnel Positive Tinel’s and Valleix's sign Tarsal Tunnel Syndrome In a study published in Foot and Ankle International, Trepman et al. proved that eversion and inversion of the foot and ankle increased pressure in the tarsal tunnel, contributing to symptoms associated with entrapment of the posterior tibial nerve By obtaining the MR I of 13 ankles in nine healthy subjects in three positions (neutral, eversion, and inversion), the authors observed that the mean tarsal tunnel volume was significantly greater when the foot and ankle were in the neutral position rather than in the full eversion or inversion. The findings of this study imply that maintaining the foot and ankle in a neutral position can help in the treatment and management of tarsal tunnel syndrome by reducing pressure on the posterior tibial nerve and maximizing compartment volume of the tarsal tunnel. Tarsal Tunnel Syndrome What are some of Treatment of TTS the risk factors and plantar fasciitis these two causes are quite similar of heel pain share? Plantar Fasciitis Risk Factors Biomechanical abnormalities Overly tight calf muscle Poor shoe choices Weight gain Barefoot walking Work surface Trauma Plantar Fasciitis Evaluation & Diagnosis Pain with pressure on bottom of heel or arch Limping Foot Type: low vs. high arch, pronation X-ray findings – Spur? Other abnormalities? Ultrasound Nerve Conduction Velocity studies to evaluate potential nerve problems MRI –rarely used. Mostly for chronic, unresponsive cases Plantar Fasciitis Treatment Mechanical – treat the cause Anti-inflammatory – treat the pain Neither done in isolation Plantar Corticosteroid injections Fasciitis Taping (Low Dye) Treatment Running shoes Orthotics What I Dry Needling learned in Plantar fasciotomy training Plantar Fasciitis Treatment Stretching, shoe modifications, avoid walking barefoot Icing and rest Night or resting splint Supplemental arch support (OTC vs. custom orthotics) Anti-inflammatory medication Steroid injections Physical therapy If conservative measures fail, surgery is an option Plantar Fasciitis Treatment What I do now If there is any burning, tingling, numbness or sharp shooting pain worse at night I order NCV, EMG. If there is any HX of claudication, rest pain or diminished pulses we schedule a PAD exam. Bilateral digital x-rays to r/o stress fracture, tumor or other osseous abnormalities. When I see heel spurs plantar or retrocalcaneal I suspect a tight posterior muscle group. Ultrasound exam and injection if the pain level warrants it and the patient is okay with needles. If no shot then diclofenac gel 4 grams topically to heel qid Low Dye strapping and/or Swedo brace. Measure for Saucony stability shoes Plantar Fasciitis Treatment What I do now Muscle strength testing including heel raise (PTTD) Check for Tinel’s and Valleix's sign to R/O tarsal tunnel Check for equinus if there is less than 10 degrees of dorsiflexion an Equinus Brace is dispensed. After two weeks in the Equinus Brace stability shoes are dispensed After two weeks in stability shoes and four weeks in EQ brace OTC orthotics are dispensed At this point 90% of patient have a pain level of 2/10 or less. If pain is still significant a repeat injection or 4 weeks of meloxicam Other options for heel pain Over 90% of heel pain patients respond to initial therapies within a relatively short period of time For unresponsive cases, options include: Minimally invasive procedures like ESWT (Extracorporeal Shock Wave Therapy) Autologous Platelet Concentrate (APC) injection Surgical procedures, open or endoscopic Cryosurgery Radiofrequency techniques Low Dye Strapping CPT 29540 Low Dye Strapping CPT 29540 Low Dye Strapping CPT 29540 Amis – Frontiers in Surgery 2016 The Split Second Effect: The Mechanism of How Equinus Can Damage the Human Foot and Ankle "We are awakening to a new era of understanding the mechanics and function of the human foot and ankle. There is a simple, singular, usually silent, and remote cause for the majority of non- traumatic acquired foot and ankle pathology, and mechanically, it creates cumulative damage to the foot and ankle through leveraged forces. In short and in this author’s opinion, equinus is the primary mechanical common denominator that leads to the majority of acquired non-traumatic foot and ankle problems by indirect leveraged means as well as direct forces along the posterior/plantar chain. There can be no more room for the James Amis, MD standard thinking that these resultant foot and ankle problems arise just because we are getting older or we are obese or they are just random, or that an equinus contracture is only a part of the equation. Equinus is the equation." Silfverskiöld Exam position hindfoot in supination examination technique Dayton et al. JFAS 2017 Experimental Comparison of the Clinical Measurement of Ankle Joint Dorsiflexion and Radiographic Tibiotalar Position “Motion of the foot between the neutral and supinated positions introduced an additional source of potential error from the measurement technique when using the neutral position as the standard, which has been recommended in the past. We recommend a supinated foot position as a more reliable foot position for measuring the clinical ankle joint range of motion and propose it as a potential standard.” Liu & Xie HSSJ 2016 Association between Achilles tightness and lower extremity injury in children page 033 Hill JAPMA 1995 Ankle equinus.
