What is the appropriate treatment and management for a patient with a tibial head fracture, particularly those with a history of osteoporosis or previous fractures?

Management of Tibial Plateau (Tibial Head) Fractures in Patients with Osteoporosis

For patients over 50 years with a tibial plateau fracture and osteoporosis history, immediate orthopedic stabilization must be coupled with systematic fracture liaison service enrollment and bisphosphonate initiation within 3-6 months to prevent the high risk of subsequent fractures that peaks immediately post-injury. 1

Acute Fracture Management

Initial Stabilization Strategy

High-energy tibial plateau fractures require staged management with temporary spanning external fixation followed by delayed definitive fixation once soft tissues permit. 2

• Place knee-spanning external fixation on day of admission for all high-energy proximal tibia fractures (OTA types 41A, B, C) to achieve osseous stabilization, allow soft-tissue access, and prevent further articular damage 2
• Delay definitive internal fixation until the soft-tissue envelope recovers, typically 7-14 days, which reduces deep wound infection rates to approximately 5% 2
• This staged approach is particularly critical in patients with osteoporotic bone where initial trauma may be more extensive 2

Definitive Surgical Fixation

• Use locking plates with angular stability for definitive fixation in osteoporotic bone, which avoids the need for bilateral plating in most situations 3
• Arthroscopically-assisted treatment is reserved only for tibial eminence fractures, crack fractures, and simple impression fractures 3
• For comminuted fractures in osteoporotic patients with low compliance, hybrid external fixation may be the optimal alternative to internal fixation 3

Critical Complication Monitoring

• Monitor aggressively for compartment syndrome, which presents as pain out of proportion to injury or increasing narcotic requirements—this remains the most significant early complication regardless of treatment method 4
• Watch for deep wound infections (5% incidence), nonunion (4%), and knee stiffness (<90 degrees in 4% of cases) 2

Secondary Fracture Prevention: The Critical Component

Mandatory Fracture Liaison Service Enrollment

Every patient aged 50 years and over with a tibial plateau fracture must be systematically evaluated through a Fracture Liaison Service (FLS), which is the most effective organizational structure for preventing subsequent fractures. 1

• The FLS coordinator (typically a specialized nurse under orthopedic/rheumatology supervision) identifies all elderly fracture patients, organizes diagnostic investigations, and initiates treatment 1
• FLS implementation increases appropriate osteoporosis management to 45% within 6 months versus only 26% in standard care 1
• Secondary fracture risk is highest immediately after the initial fracture and gradually decreases over time, making urgent evaluation within 3-6 months essential 1

Comprehensive Fracture Risk Assessment

Perform the following evaluations within 3-6 months post-fracture:

• DXA scanning of spine and hip to measure bone mineral density (BMD), which independently contributes to fracture risk assessment 1
• Spine imaging (radiography or vertebral fracture assessment) to detect subclinical vertebral fractures, which are frequent in patients with non-vertebral fractures and independently predict future fracture risk 1
• FRAX, Garvan, or Q-Fracture risk calculator incorporating age, gender, BMI, personal/family fracture history, and falls risk 1
• Falls risk evaluation starting with history of falls in the past year, followed by specific balance testing 1
• Laboratory screening: ESR, serum calcium, albumin, creatinine, TSH, vitamin D level, and consider protein electrophoresis or testosterone in men 1

Pharmacological Osteoporosis Treatment

First-Line Therapy: Oral Bisphosphonates

Initiate oral bisphosphonates (alendronate or risedronate) as first-line treatment for patients at moderate-to-high fracture risk, as these reduce vertebral fractures by 65% and non-vertebral fractures by 53%. 1, 5

• Alendronate and risedronate are preferred due to proven efficacy in reducing vertebral, non-vertebral, and hip fractures, low cost (generics available), good tolerability, and extensive clinical experience 1, 5
• Treatment duration should be 3-5 years initially, with continuation in patients who remain at high risk 1, 5
• In elderly patients with typical fragility fracture patterns, consider initiating anti-osteoporotic therapy even before DXA results are available 6

Alternative Agents When Bisphosphonates Are Inappropriate

If oral bisphosphonates are contraindicated due to gastrointestinal intolerance, malabsorption, dementia, or non-compliance:

• Intravenous zoledronic acid (the only drug specifically studied after recent hip fracture) 1
• Subcutaneous denosumab for patients requiring non-oral administration 1
• Teriparatide for patients with very high fracture risk or severe osteoporosis 1

Essential Adjunctive Therapy

• Calcium 1,000-1,200 mg/day (dietary plus supplementation as needed) 1, 5
• Vitamin D 800 IU/day (target serum level ≥20 ng/ml), which reduces non-vertebral fractures by 15-20% and falls by 20% 1, 5
• Avoid high-pulse dosages of vitamin D, which paradoxically increase fall risk 1

Rehabilitation Protocol

Early Mobilization

Begin range-of-motion exercises within the first postoperative days to prevent debilitating knee stiffness while maintaining stable fixation. 7, 6

• Initiate finger and upper extremity motion exercises immediately for all non-immobilized joints 6
• Balance training and multidimensional fall prevention programs must continue long-term 1, 6
• Avoid prolonged immobilization, which leads to stiffness and poorer functional outcomes 7
• However, avoid overly aggressive early therapy that may compromise fixation 7

Expected Outcomes

• Mean knee range of motion at final follow-up: 1° to 106° (SD 15°) 2
• Residual knee stiffness is a potential downside of staged external fixation, occurring in approximately 4% of patients 2
• Patients with post-traumatic osteoarthritis who eventually require total knee arthroplasty have higher complication rates and more pain compared to primary osteoarthritis patients 8

Non-Pharmacological Interventions

• Smoking cessation and alcohol limitation (≤1-2 drinks/day) due to negative effects on BMD, bone quality, and fall risk 1, 5
• Weight-bearing and resistance training exercises to maintain bone density 1, 5
• Maintain weight in recommended range 1, 5

Orthogeriatric Co-Management

For frail elderly patients with multiple comorbidities and polypharmacy, implement orthogeriatric co-management during the acute fracture care phase. 1, 6

• This multidisciplinary approach improves outcomes in elderly patients with major fractures 1
• Coordinate care between orthopedic surgeons, rheumatologists/endocrinologists, geriatricians, and primary care physicians 1

Treatment Adherence and Follow-Up

• Systematic follow-up is essential as long-term adherence to osteoporosis treatment is typically poor 1
• FLS programs achieve up to 90% adherence rates, likely because patients are more motivated after experiencing a fracture 1
• Risk communication and shared decision-making positively influence adherence 1
• Regular monitoring for tolerance and adherence to prescribed treatments is mandatory 1, 6

Critical Pitfalls to Avoid

• Never dismiss a tibial plateau fracture in a patient over 50 as simply traumatic—it may represent underlying fragility requiring comprehensive osteoporosis evaluation 6
• Do not wait for complete pain resolution before beginning rehabilitation exercises, as this leads to permanent stiffness 6
• Failure to address underlying osteoporosis leaves patients at dramatically increased risk of subsequent hip or vertebral fractures, which carry significant mortality risk 6
• Do not perform bilateral plating when modern locking plates with angular stability can achieve adequate fixation 3
• Avoid immediate definitive fixation in high-energy fractures with compromised soft tissues—stage the procedure 2
