Summary
Nonunion of ankle malleoli is rare, often linked to infection after surgery. Treatment for painful nonunions involves fragment resection or stabilization with screws and bone grafts, while infected cases require osteitis therapy.
Area of Science:
- Orthopedic Surgery
- Traumatology
- Bone Healing
Background:
- Ankle malleoli nonunion is infrequent, largely due to the shift from conservative management to primary osteosynthesis for ankle fractures.
- Current nonunions are predominantly observed in infected cases following surgical interventions.
- Non-infected, stable, and asymptomatic nonunions typically do not necessitate surgical intervention.
Purpose of the Study:
- To outline current therapeutic strategies for ankle malleoli nonunion.
- To differentiate treatment approaches based on infection status and symptom presentation.
- To detail surgical techniques for managing painful nonunions and bony defects.
Main Methods:
- Review of nonunion cases, distinguishing between infected and non-infected presentations.
- Surgical techniques discussed include fragment resection, screw fixation (3.5-mm cancellous screws), tension banding (especially for Weber A fractures), and bone grafting.
- Management of infected nonunions follows established osteitis treatment protocols.
Main Results:
- Non-infected, stable, and painless nonunions generally do not require surgical correction.
- Painful nonunions with small fragments may benefit from resection, while larger fragments require stabilization.
- Tension banding and bone grafting are effective for specific fracture types and bony defects.
Conclusions:
- Effective management of ankle malleoli nonunion hinges on precise remodeling, bone grafting, and stabilization.
- Infected nonunions with significant bone loss demand treatment guided by osteitis therapy principles.
- The approach to nonunion treatment must be tailored to the specific clinical scenario, including fragment size, stability, and infection presence.
