Hallux (Big Toe) Limitus & Rigidus Series
Part 6 Contraindications (When Orthotics Aren’t Recommended)
While orthotics are beneficial for most cases of Hallux Limitus & Rigidus, certain conditions may limit their effectiveness or require alternative approaches(such as special types of orthotics), we will explore these in this post.
1. Severe Joint Ankylosis (Complete Fusion of Bones)
– If the first metatarsophalangeal (MTP) joint (Big Toe) is already fused naturally, orthotics may not provide additional benefit.
– A rocker-bottom shoe may be more effective than an orthotic in such cases.
2. Severe Osteophyte Formation with Impingement (Bone Spurs causing problems in other areas)
– In advanced Hallux Rigidus, large bone spurs may cause excessive dorsal (top of the foot) pressure, making orthotics uncomfortable.
– Surgical intervention (cheilectomy or fusion) may be necessary before using orthotics.
3. Peripheral Neuropathy (Numbness or Pain in Nerves) or Diabetes with Ulcer (Extreme Wound) Risk
– Patients with reduced sensation (e.g., from diabetic neuropathy) may not perceive excessive pressure from a Morton’s extension or rigid plate. If they feel pressure they should address it, but unfortunately in these cases they won’t feel it to know.
– Custom diabetic-friendly orthotics with soft accommodations may be needed instead.
4. Rheumatoid Arthritis (RA) or Inflammatory Joint Disease
– If Hallux Limitus is secondary to RA or gout, rigid orthotics may increase discomfort.
– Accommodative orthotics with extra cushioning are preferred.
5. Active Infection or Open Wounds
– If the patient has an ulcer, wound, or skin infection, wearing orthotics could worsen the condition by irritating the area.
– Offloading devices like total contact casts or wound care orthotics should be used first until it is healed, then regular orthotics can be explored.
There may be other conditions or situations that weren’t mentioned here, it’s always best to check with your doctor or foot specialist before starting orthotics (even over the counter ones).
