Stress Fracture When Activity Modification and Conservative Management Did Not Achieve Pain-Free Recovery
Clinical Scenario
When a bone stress injury fails to respond to a structured first-line conservative programme, the clinical pathway moves to a more targeted intervention. This protocol defines that next step and the criteria that guide it.
Previous Treatment — Goals Not Achieved
The prior management included activity modification, protected weight-bearing and immobilisation for lower extremity injuries, structured physical therapy incorporating multi-directional and osteogenic activities, nutritional counselling, vitamin D supplementation (where serum levels were insufficient), and addressing lifestyle factors such as sleep and psychological stress.
Escalation to this protocol is indicated when the following benchmarks were not reached:
- Pain-free during daily or sports activities
- Pain-free palpation at the bone stress injury site
- Negative bone loading tests (e.g. single-leg hopping test)
- No pain with running at the injury site
Next-Step Approach (Partial Overview)
This protocol centres on surgical fixation. Site-specific considerations apply: for fifth metatarsal and navicular bone stress injuries, distinct guidance governs the choice of technique and the surgical-versus-non-surgical decision. The full algorithm, indications, and site-specific criteria are detailed in the complete protocol.
Treatment Goals
- Pain-free during daily and sports activities
- Pain-free palpation of the bone stress injury site
- Negative bone loading tests (e.g. single-leg hopping test)
- No pain with running at the injury site

- Elite athletes may consider surgery, particularly with the goal of facilitating early return to sport.
- When considering surgical treatment, panellists may support the decision based on features including delayed union (no signs of union >3 months), non-union (no signs of union >6 months), recurrent injury, fracture displacement and injury site being prone to treatment complications.
- Surgical management of bone stress injuries in select cases (eg, navicular, anterior tibia, fifth metatarsal) may allow for early return to sports and can be considered in elite athletes.
- If treated surgically, preferred surgical technique of bone stress injuries of the fifth metatarsal (non-displaced) is fixation using an intramedullary screw.
- For navicular bone stress injuries, decision-making on surgical vs non-surgical treatment should include fracture type (eg, classification by Saxena et al).
