Surgical Management of Stress Fractures of the Foot and Ankle: Beyond Allied Health Sports/Surgeon Series
It was a pleasure to be invited to present for Beyond Allied Health (movebeyond.com.au) as part of their Surgeon and Sports Doctor Education Series — an initiative specifically designed to bridge the knowledge gap between surgeons, sports physicians, and allied health clinicians in Melbourne and beyond.
The Evening
The event brought together a predominantly allied health audience — physiotherapists, podiatrists, exercise physiologists, and sports trainers — with a focus on bone stress injuries of the lower limb. The format was well-suited to multidisciplinary learning: two speakers covered the foundational science and non-operative management of bone stress injuries before I presented on the surgical indications and operative management of stress fractures at the foot and ankle.
I had the pleasure of presenting alongside two knowledgeable colleagues. Dr Brett Frenkiel, Sports and Exercise Medicine Physician at Epworth, covered the broader framework of bone stress injury — pathophysiology, risk stratification, and the evidence base for conservative management. Ben Cherry, physiotherapist and founder of The Running Room Prahran, offered an excellent running-specific perspective on load management, return-to-run protocols, and the allied health role in identifying athletes at risk. The combination made for a well-rounded evening, and the discussion that followed was lively, with the audience clearly highly engaged.

Stress Fractures of the Foot and Ankle: A Surgical Perspective
Not all stress fractures are equal. Some heal predictably with rest and load modification. However, a subset occur at anatomical sites where the blood supply is tenuous, the mechanical forces are unfavourable, or both — and in these locations, surgery is sometimes the most reliable path to a full recovery.
My presentation focused on three of the most clinically significant stress fractures I manage as a foot and ankle surgeon in my practice at Melbourne Orthopaedic Group.
Navicular Stress Fractures
The navicular is one of the highest-risk sites for stress fracture in the foot. It sits at the apex of the medial longitudinal arch and bears significant compressive and shear load with every footfall. The central third of the navicular has a watershed blood supply, meaning this is precisely the zone where fractures occur — and where healing is most unpredictable.
Navicular stress fractures are notorious for being missed, often presenting as vague midfoot pain that has been attributed to plantar fasciitis or tibialis posterior tendinopathy. Plain X-rays are frequently normal; CT scanning remains the gold standard for diagnosis and fracture characterisation. MRI is invaluable for detecting early stress reactions before frank fracture occurs.
Surgical management is indicated for complete fractures, fractures with displacement, those that have failed a period of strict non-weight-bearing, or in elite athletes where the time demands of conservative management are prohibitive. I presented on the technique of percutaneous screw fixation through the navicular, which provides rigid stabilisation and allows earlier mobilisation than prolonged casting alone.
Fifth Metatarsal Stress Fractures (Jones Fracture Zone)
Stress fractures at the base of the fifth metatarsal — specifically within the proximal diaphysis at the metaphyseal-diaphyseal junction, the so-called Jones fracture zone — are well recognised as a high-risk injury with a significant rate of delayed union and non-union when managed conservatively. This is partly attributable to the relatively poor blood supply at this site and the considerable tensile and bending forces the fifth metatarsal experiences during push-off and lateral movements.
These fractures are common in jumping and cutting sports, and I see them frequently in AFL players, basketballers, and distance runners. In active individuals — and certainly in competitive athletes — I favour early intramedullary screw fixation. This provides reliable compression across the fracture site, dramatically reduces the risk of non-union, and allows a significantly faster return to sport compared with non-operative management. Bone grafting is occasionally necessary in the setting of established non-union or sclerotic fracture margins.
Stress Fractures at the Ankle: Distal Tibia and Medial Malleolus
Stress fractures of the distal tibia are relatively common in endurance athletes and military recruits, and the majority respond well to relative rest and load modification. However, fractures involving the anterior cortex of the distal tibia — the so-called “dreaded black line” on lateral radiograph — are prone to delayed union and, in the worst case, complete fracture with displacement. These warrant careful consideration of operative stabilisation, particularly in athletes who cannot sustain a prolonged period away from training.
Medial malleolar stress fractures are rarer but clinically important. They typically arise from repetitive compressive loading at the tibiotalar joint and can propagate toward the plafond if unrecognised. CT is essential for defining fracture anatomy. Surgical fixation with cannulated screws is my preferred approach for established fractures, as it eliminates the risk of propagation and allows predictable return to activity.
A Note on the Allied Health Audience
Evenings like this serve an important function. Allied health practitioners are frequently the first to encounter athletes and active patients with stress fractures — often before they reach a surgeon. Improving pattern recognition, understanding which injuries warrant urgent imaging or referral, and knowing when to escalate to a surgical opinion are all critical competencies for the allied health community. It was a genuine pleasure to present in this context, and the questions from the floor demonstrated a sophisticated and engaged audience.
Stress Fractures of the Foot and Ankle in Melbourne
If you have a patient — or are yourself an athlete — with suspected bone stress injury or a stress fracture of the foot or ankle, early and accurate assessment is essential to avoid delayed diagnosis and ensure the right treatment pathway. I see these injuries regularly at Melbourne Orthopaedic Group in Windsor and work closely with sports physicians, physiotherapists, and sports podiatrists to deliver comprehensive, coordinated care.
