Long-Term Chest Wall Deformity Surveillance and Pulmonary Function Tests
In short
Long-term clinical surveillance for chest wall deformity, volume loss, and restrictive defects using serial Pulmonary Function Tests (PFTs).

In this guide (2 sections)
While the acute crisis of blunt thoracic trauma resolves within weeks, long-term structural and physiological surveillance remains essential for optimal lifelong health. Severe multiple rib fractures, particularly when treated non-operatively, frequently consolidate with significant structural deformities, including thoracic cage asymmetry, rib overlap, chest wall volume loss, and persistent flail depression deformities. Serial clinical evaluations paired with objective Pulmonary Function Tests (PFTs) at 3, 6, and 12 months track physiological recovery, identify emerging restrictive defects, and guide ongoing corrective exercise.
Structural Volume Loss and Restrictive Ventilatory Mechanics
When displaced rib fractures heal conservatively without surgical realignment, fragments frequently heal with overlapping ends, angular malunion, or inward depression. This anatomical shortening decreases the total cross-sectional volume of the hemithorax. Over subsequent months, fibrotic contraction of surrounding intercostal muscles and pleural thickening further rigidify the compromised chest wall. On spirometry, this anatomical restriction manifests as proportional reductions in both Forced Vital Capacity (FVC) and Forced Expiratory Volume in 1 second (FEV1), while maintaining a normal or elevated FEV1/FVC ratio (>0.75), the hallmark of an extrinsic restrictive ventilatory defect.
| Follow-Up Milestone | Diagnostic Evaluation | Key Clinical Parameters | Rehabilitation Objective | |
|---|---|---|---|---|
| Month 3 Post-Injury | Baseline Spirometry & Chest X-Ray | FVC, FEV1, bony union check, contour symmetry | Assess early restrictive defect; progress resistance training | |
| Month 6 Post-Injury | Full PFTs (Plethysmography, DLCO) | Total Lung Capacity (TLC), gas diffusion capacity | Target TLC > 80% predicted; advanced aerobic conditioning | |
| Month 12 Post-Injury | Final Functional & PFT Surveillance | 6-Minute Walk Test, long-term deformity score | Confirm permanent respiratory reserve; discharge to wellness |
Physiotherapy Corrective Exercises for Thoracic Asymmetry
When serial surveillance reveals persistent chest wall asymmetry or mild volume depression, corrective exercise protocols are prescribed to maximize residual compliance. The physiotherapist employs asymmetric expansion drills: positioning the patient in side-lying over a firm foam roll positioned beneath the unaffected side, forcing the depressed, affected hemithorax to expand upward against gravity during deep inspiration. This targeted expansion stretches contractured intercostal tissues and maximizes alveolar recruitment.
5-Step Asymmetric Hemithoracic Expansion Drill
Objective: Targeted expansion of a depressed or asymmetric hemithorax to maximize lung volume.
- 1Lie on your uninjured side on a firm mat, placing a small rolled towel beneath your lower rib cage.
- 2Drape your top arm (on the injured side) overhead, resting it comfortably along your ear.
- 3Take a slow, deep nasal breath, actively directing airflow into the upper, injured side of your rib cage.
- 4Hold the maximal expanded breath for 4 seconds, feeling the depressed ribs lift upward toward the ceiling.
- 5Exhale smoothly through relaxed lips, repeating for 8 controlled asymmetric expansion breaths.
Navigating Routine Health Checkups in Indian Healthcare
In India, patients often skip follow-up hospital appointments once acute symptoms resolve, assuming that absence of pain equals complete recovery. Physiotherapists and family members must emphasize the importance of scheduled 3-month and 6-month checkups. Having a formal spirometry test conducted at a local diagnostic pulmonary clinic provides objective confirmation that lung capacity is returning to normal, ensuring peace of mind for the patient and family.
Long-Term Rehabilitation Trajectory and Clinical Follow-Up
Over the course of a full year, the vast majority of patients with well-rehabilitated thoracic trauma achieve normal or near-normal pulmonary function parameters. Consistent adherence to long-term mobility and aerobic drills ensures excellent exercise tolerance and a full return to vocational and recreational activities.
If serial spirometry demonstrates a progressive, worsening decline in Forced Vital Capacity (FVC) over time, refer immediately for high-resolution chest computed tomography to evaluate for developing post-traumatic fibrothorax, pleural thickening, or diaphragmatic herniation.
Why do I need a lung function test months after my broken ribs have healed?
A lung function test measures how much air your lungs can hold and how fast you can blow it out. It gives your medical team objective proof that your chest wall is expanding fully and that no permanent stiffness or lung volume loss remains after your injury.
Do I need a doctor referral to consult a home physiotherapist in India?
Under the National Commission for Allied and Healthcare Professions (NCAHP) Act 2021, patients in India have direct access to registered physiotherapists without requiring a physician referral. At BookPhysio.in, you connect with verified physiotherapists and pay directly per session, with zero advance fees, zero package lock-ins, and no platform commissions.
