What is the rehabilitation protocol for an adult patient with a trimalleolar fracture fixation and no significant comorbidities?

Rehabilitation Protocol for Trimalleolar Fracture Fixation

Begin immediate finger and toe motion exercises within the first postoperative days, followed by early weight-bearing as tolerated (typically 6-8 weeks post-fixation), combined with aggressive physical therapy focusing on range of motion, muscle strengthening, and long-term balance training to prevent falls and subsequent fractures. 1

Immediate Postoperative Phase (Days 0-7)

Pain Management and Basic Care

• Administer regular paracetamol with carefully prescribed opioid analgesia as needed during remobilization 1
• Provide supplemental oxygen for at least 24 hours postoperatively to prevent hypoxia 1
• Encourage early oral fluid intake rather than routine IV fluids, and remove urinary catheters as soon as possible 1
• Monitor for postoperative cognitive dysfunction (occurs in 25% of fracture patients) through adequate analgesia, nutrition, hydration, and early mobilization 1

Early Motion Exercises

• Start finger and toe motion immediately after surgery to prevent edema and stiffness 2
• Begin ankle range-of-motion exercises including dorsiflexion, plantarflexion, inversion, and eversion within the first postoperative days 1
• Restrict above-neutral dorsiflexion activities until fracture healing is evident to avoid fixation failure 1

Early Rehabilitation Phase (Weeks 2-8)

Progressive Weight-Bearing

• Initiate protected weight-bearing as tolerated, typically beginning at 6 weeks post-fixation once radiographic healing is evident 3, 4
• Use assistive devices (walker, crutches) during the transition to full weight-bearing 3
• Avoid prolonged non-weight-bearing beyond 8 weeks, as this causes muscle wasting and reduced ankle range of motion 3

Physical Training and Muscle Strengthening

• Begin early postfracture introduction of physical training and muscle strengthening exercises 1
• Focus on lower limb muscle strengthening including quadriceps, hamstrings, gastrocnemius, and tibialis anterior 3
• Use Mulligan's movement with mobilization techniques to increase ankle dorsiflexion range if restricted 3
• Apply therapeutic ultrasound to improve scar mobility if needed 3

Intermediate Rehabilitation Phase (Weeks 8-16)

Advanced Functional Training

• Progress to aggressive ankle range-of-motion exercises once immobilization is discontinued 2
• Implement proprioception training to restore balance and joint position sense 3
• Begin gait training to normalize walking patterns and prevent compensatory movements 3
• Continue muscle strengthening with progressive resistance exercises 1

Functional Outcome Monitoring

• Assess progress using validated outcome measures (MOXFQ, FADI, or AOFAS scores) 4
• Monitor for radiological union, which typically occurs at 7-8 weeks (range 5-16 weeks) 4

Long-Term Rehabilitation Phase (Months 4-12+)

Balance Training and Fall Prevention

• Continue long-term balance training and multidimensional fall prevention programs 1
• Implement exercise programs that improve bone mineral density and muscle strength while reducing fall frequency 1, 2
• Maintain physical activity levels to prevent deconditioning 1

Secondary Fracture Prevention

• Systematically evaluate all patients aged 50+ for subsequent fracture risk 1, 2, 5
• Ensure adequate calcium intake (1000-1200 mg/day) combined with vitamin D supplementation (800 IU/day), which reduces non-vertebral fractures by 15-20% and falls by 20% 1, 2, 5
• Consider pharmacological treatment with bisphosphonates (alendronate or risedronate) for high-risk patients to reduce subsequent fracture risk by approximately 50% 5

Multidisciplinary Coordination

Team-Based Approach

• Coordinate care between orthopedic surgeons, physical therapists, occupational therapists, and primary care physicians 1, 2
• Identify individual goals and needs early before developing the rehabilitation plan 1, 2
• Provide patient education about disease burden, risk factors for fractures, follow-up requirements, and expected duration of therapy 1, 2

Critical Pitfalls to Avoid

• Do not delay mobilization due to fear of pain, as prolonged non-weight-bearing causes muscle wasting and reduced ankle function 3
• Avoid overly aggressive physical therapy in the early postoperative period (first 6 weeks), as this may increase risk of fixation failure 1
• Do not neglect long-term balance training, as the risk of subsequent fractures remains elevated for 24 months post-injury 5
• Avoid delaying fracture risk assessment and osteoporosis treatment in patients over 50, as they have already demonstrated bone fragility 5, 6
