Upper Extremity Movement Caps in Concomitant Clavicle and Rib Trauma
In short
Understand upper extremity range of motion restrictions when clavicle fractures occur alongside upper rib fractures. Safe mobilization protocols.
In this guide (2 sections)
High-impact blunt trauma frequently results in concurrent injuries to the clavicle and underlying upper ribs (ribs one through four). This combination is particularly precarious because the clavicle serves as the primary bony strut connecting the upper limb to the axial skeleton. When both the clavicle and adjacent ribs are fractured, the structural integrity of the shoulder girdle is severely destabilized, a condition known as a variant of the 'floating shoulder.' In these complex injuries, uncontrolled arm movements can exert massive torsional and distraction forces across both fracture sites. Implementing strict active range of motion caps during early rehabilitation is vital to safeguard healing bone and neurovascular structures.
Biomechanical Interdependence of Clavicle and Upper Thoracic Cage
During shoulder elevation above 90 degrees, the clavicle must rotate upward and backward approximately 30 to 45 degrees along its longitudinal axis at the sternoclavicular and acromioclavicular joints. Additionally, upper ribs must elevate and expand to accommodate full scapulohumeral rhythm. When the clavicle is fractured (whether managed conservatively or with open reduction and internal fixation plating), elevating the arm above shoulder height generates substantial rotational torque across the clavicular fracture line and pulls directly on the subclavius and pectoralis minor muscles attached to ribs one and two. To prevent hardware failure, non-union, or brachial plexus irritation, active shoulder flexion and abduction must be strictly capped at 90 degrees for the initial three to four weeks.
| Rehabilitation Phase | Permitted Shoulder ROM | Mechanical Protection | Permitted Daily Activities | |
|---|---|---|---|---|
| Phase 1 (Weeks 1 to 3) | Capped at 90° flexion & abduction | Sling support, pendulum drills, elbow/wrist active ROM | Eating, typing, writing with arm supported close to body | |
| Phase 2 (Weeks 4 to 6) | Progress to 120° elevation | Active-assisted wall climbs, gentle isometric rotators | Light dressing, bathing, carrying items under 1 kg | |
| Phase 3 (Weeks 7 to 12) | Full unrestricted active ROM | Graded resistance strengthening, overhead reaches | Full domestic activities, driving, non-contact work |
Physiotherapy Execution Below the 90-Degree Horizon
During the initial phase, the physiotherapist ensures that the 90-degree movement ceiling is strictly respected. The patient is instructed in supported pendular exercises (Codman's exercises) to maintain glenohumeral capsular mobility without activating deltoid or supraspinatus contractions that could strain the clavicle. Active elbow, wrist, and hand exercises are performed several times daily to prevent distal edema and stiffness.
Supported Tabletop Slide Drill (Under 90 Degrees)
Objective: Maintain shoulder forward reach and mobility without exceeding the safe 90-degree elevation limit.
- 1Sit upright facing a smooth dining table or desk, placing a soft cotton towel beneath your palms.
- 2Rest both forearms on the table with elbows bent comfortably at 90 degrees.
- 3Slowly slide the towel forward along the table surface by leaning gently from the hips.
- 4Stop the forward slide before the arms reach shoulder height (maintaining an angle below 90 degrees).
- 5Slide back smoothly to the starting posture by gently pushing downward through the palms, repeating for 8 controlled repetitions.
Practical Dressing and Personal Care in Indian Households
In Indian domestic life, dressing presents major hurdles when arm movement is restricted to 90 degrees. Patients should wear front-button kurtas or loose shirts, completely avoiding tight t-shirts or banian vests that require overhead pulling. When dressing, always insert the injured arm into the sleeve first; when undressing, remove the healthy arm first. Family members should assist with washing hair, as lifting both arms to shampoo requires overhead movements that violate the 90-degree precaution.
Long-Term Rehabilitation Trajectory and Clinical Follow-Up
At the four-week mark, repeat radiographs evaluate clavicular alignment and early callus formation. Once union is confirmed, the 90-degree ceiling is lifted. Active-assisted exercises progress toward full overhead elevation, followed by progressive rotator cuff and scapular stabilizer strengthening over the subsequent eight weeks.
Report any new numbness, tingling, or weakness radiating down the arm into the hand or fingers immediately. Proximity of upper rib and clavicular fractures to the brachial plexus and subclavian vessels warrants urgent clinical evaluation if neurological symptoms appear.
Why am I not allowed to lift my arm above shoulder height for the first month?
Lifting your arm above shoulder level forces your collarbone to rotate and twist against your broken upper ribs. Restricting movement below shoulder height for four weeks protects the healing bone fragments and surgical plates from snapping or shifting out of place.
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.
