Principles of foot immobilization and offloading
Fusion of bone fragments requires an adequate period of rest, the duration of which is determined by the patient's age and the severity of the injury:
- For uncomplicated fractures in adults: a cast is applied up to the lower third of the leg for a period of 4 to 6 weeks.
- In children: for injuries without displacement or with minimal displacement, a splint-cast up to the upper third of the leg is applied for 3–4 weeks.
A critically important condition during the cast application stage is thorough modeling of the foot arch, which prevents flattening and reduces the risk of post-traumatic deformities during subsequent weight-bearing.
Orthopedic regimen in the post-immobilization period
After cast removal, weight-bearing function is restored gradually. The weakened ligamentous apparatus and consolidating bone tissue require additional protection:
- A mandatory rule of rehabilitation is continuous wearing of arch supports for at least 6 months.
- Orthopedic insoles support the anatomical longitudinal and transverse profile, compensating for the mechanical pressure of body weight on the forefoot and midfoot.
Stimulation of bone regeneration and drug therapy
The post-traumatic period is accompanied by catabolic reactions, requiring comprehensive metabolic and pharmacological correction:
- Dietary nutrition: a high-calorie diet rich in proteins and micronutrients (meat, fish, eggs, fermented dairy products, fresh vegetables and fruits), with mandatory blood sugar control in the first days after the injury.
- Basic medications: painkillers, amino acid and protein complexes, B vitamins.
- Mineral support: calcium supplements are introduced strictly from the second phase of osteoregeneration — starting from days 10–14 after the injury.
- Biogenic stimulants: a course of aloe extract, FiBS, or vitreous body injections to activate reparative processes.
Physical therapy modalities
Physical therapy methods are selected taking into account the stage of fracture consolidation:
- UHF therapy: deep thermal effect relieves local inflammation and manages pain syndrome.
- Magnetotherapy: activates tissue metabolism, stimulates bone healing, and provides an analgesic effect.
- Laser and electrical stimulation: application to the fracture area improves local trophic supply and accelerates repair.
- Hyperbaric oxygenation (HBO): tissue saturation with oxygen under pressure eliminates local ischemia.
- Acupuncture: serves as an additional pain management method.
- Balneotherapy: used in the rehabilitation phase to normalize soft tissue mobility and tone.
The "3-C" rule of foot rehabilitation: Cast (arch molding and arch support for 6 months), Calcium (strictly from day 10–14), Complex PT (magnet, laser, heat).
Class and exam questions
Why is it mandatory to wear an arch support for at least 6 months after cast removal?
The arch support is necessary to maintain and protect the anatomical arches of the foot from flattening and deformation under axial load during the period of final bone callus remodeling.
When is it permitted to start taking calcium supplements during bone healing?
Calcium supplements are prescribed only with the onset of the second stage of bone regeneration, i.e., on the 10th–14th day after the injury.
What is Jacobson's sign in forefoot injuries?
This is the appearance or sharp intensification of pain directly in the fracture zone upon palpation pressure on the head of the corresponding metatarsal bone from the plantar side.
