Clinical Outcomes Following Percutaneous Ankle Fusion With Bone Graft Substitute

The efficacy of shoes modification and orthotics in hallux valgus deformity: a comprehensive review of literature

Hallux valgus (HV) is a frequent forefoot deformity affecting about 23% of adults and 35.7% of people over 65. The exact etiology is not fully understood. The first ray plays a significant role in walking cause it bears the principal amount of weight and maintains the position of the medial arch. Several factors that deteriorate the integrality of the first ray, such as foot deformities, restrictive footwear, and pes planus, may be ascribed to the HV occurrence. Before any surgical correction, conservative treatment should always be initiated first. Currently, there is no consensus that conservative management by shoe modification and foot orthoses could correct the pathology or terminate the clinical worsening of the condition.From a careful analysis of the literature, proper footwear should be a shoe with an adequate length, wide toe box, cushioned sole, and a lowered heel to not increase the load on the metatarsal heads and cause pain. Personalized 3D printed customized toe spreaders may be applied in patients with HV, improving symptoms and bringing pain relief. Compensating the subtalar joint hyperpronation through foot orthoses plays a fundamental role in the HV development, preventing or at least controlling the condition's progress; this, along with weight reduction and regular physical activity.Data obtained suggest that dynamic foot orthoses prefer a biomechanical type with 3/4-length, which is less likely to negatively affect the dorsal or medial pressures, which instead were noted to increase with the sulcus- and full-length orthoses.Although some studies suggest that foot orthoses would favor the correction of HV deformity, results have been very variable and just in few studies appear to correct HV or reduce its progression, improving symptoms and bringing pain relief. In the case of HV surgical correction, orthoses seem to maintain the correct position acquired over time.
