Distal Radius Fracture (ORIF) — Post-operative Rehabilitation Evidence Brief

Topic scope: post-operative rehabilitation after open reduction and internal fixation (ORIF) of a distal radius fracture with a volar locking plate. This brief backs an early-motion-but-protected hand/wrist pathway delivered with hand therapy, where wrist motion begins early while bone-dependent loading (weight-bearing, heavy lifting, contact sport) is deferred until ~12 weeks. It does not cover the indications for surgery vs casting, nor fragment-specific/dorsal/bridge-plate constructs (which carry their own loading rules).

Defining principle of the rehab here: a volar locking plate is a fixed-angle construct stable enough to permit immediate wrist motion — the screws lock to the plate and hold the articular reduction independent of the cast. So (unlike a cast-treated fracture, and unlike a tendon or ligament repair) the wrist does not need weeks of immobilisation to protect the reduction: the rehab is an early-movement pathway — finger/forearm/wrist active motion and oedema control from day one, splint for comfort only, isometric then progressive strengthening from ~weeks 4–6. The one timeline that is not negotiable is bone healing: union takes ~6–12 weeks regardless of how the wrist feels, which is why weight-bearing, heavy lifting and impact are held to 12 weeks even once motion is comfortable.

A. PROCEDURE & CONSTRUCT — what the rehab is protecting

Volar locking plate fixation is the dominant operative construct for displaced distal radius fractures and is the reference standard against which other techniques are compared. Key surgical-outcome facts that shape the rehab:

• Volar locking plates restore and hold articular reduction reliably, and across randomised comparisons give equivalent or better functional outcomes than non-operative care and competing fixation methods (dorsal plating, intramedullary nailing, fragment-specific), with most differences favouring early function rather than final endpoint [JAAOS controversies review 2014; Hand Clinics plate-fixation review 2021; IM-nail-vs-volar-plate RCTs].
• The fixed-angle construct is the rationale for early motion. Because the locking screws hold the subchondral fragments rigidly, the plate — not a cast — maintains the reduction, so wrist motion can start before union without displacing the fracture [Hand Clinics 2021; accelerated-rehab RCT, JBJS 2014].
• In older patients the operative-vs-conservative outcome gap is small. A 3-year RCT in patients >70 found volar plating and non-operative care converged on similar patient-reported function — context that keeps post-operative rehab pragmatic and patient-centred rather than aggressive [BMC Musculoskelet Disord 2022; Hand Clinics geriatric review 2021].
• Recovery is gradual. Range, grip and patient-reported scores improve steadily over the first 3–6 months; the construct permits early motion but does not accelerate the biology of healing or the return of grip strength.

B. REHABILITATION / HAND-THERAPY EVIDENCE

The central rehab questions for this construct are (1) when to start wrist motion, (2) how much supervised therapy is needed, and (3) what the strengthening timeline should be. The evidence is clear on the first, nuanced on the second, and consensus-driven on the third.

• Early motion is safe and gives a short-term advantage. Multiple RCTs and a systematic review show that starting wrist motion early after volar plating improves short-term ROM, grip and comfort without compromising the radiographic reduction [accelerated-rehab RCT, JBJS 2014; early-vs-late motion RCT, HAND 2018; Hand Therapy systematic review 2020]. This is the direct warrant for the day-1 finger/forearm/wrist program in this protocol.
• "Early" need not mean "immediate," and the advantage washes out by 3–6 months. The landmark trial comparing wrist mobilisation at ~2 weeks vs ~6 weeks found the two groups equivalent by 3–6 months [Lozano-Calderón / JBJS 2008]. So there is a genuine early benefit but no penalty for a measured, comfort-led progression — which is exactly why this protocol can be unhurried.
• Routine supervised physiotherapy adds little over a coached home program for most patients. Systematic reviews and RCTs repeatedly find that a structured home exercise program preceded by instruction/coaching performs as well as formal supervised therapy for uncomplicated cases, and that prescribed exercise programs add limited benefit over advice for impairment/activity outcomes [HEP-vs-supervised SR, J Hand Ther 2014; J Physiother SR 2017; Hand Clinics "is therapy needed?" 2021; Arch Orthop Trauma Surg 2020]. This supports a home-program-first model with hand-therapy review, escalating supervision for stiffness, oedema or slow progress — the structure of this protocol.
• Oedema control and scar/tendon-glide management are standard therapy elements. Elevation, retrograde massage, manual oedema mobilisation and (early) compression are the evidence-informed oedema toolkit [edema-management SR, J Hand Ther 2017]; scar massage to keep the flexor tendons gliding under the volar incision is consensus hand-therapy practice rather than RCT-derived.

Phased post-op timeline (volar locking plate, early-motion pathway)

Phases match this topic's synthesis.md. Timings are post-operative weeks; the 12-week loading limit is referenced to the fracture (injury) date.

The phase structure mirrors published surgeon/hand-therapy ORIF protocols (early ROM → scar + oedema → passive range + light resistance → progressive strengthening, with heavy load/sport held to ~12–16 weeks) [Physiopedia Colles' ORIF protocol; institutional ORIF rehab guidelines].

C. KEY CONTROVERSIES / EVIDENCE QUALITY

1. How early to mobilise. Early motion (immediate–2 wk) gives a real short-term ROM/grip/comfort advantage that equalises by 3–6 months vs starting at ~6 weeks. The evidence therefore supports early motion but does not mandate aggression — a measured progression is fully defensible. Moderate–strong (multiple RCTs + SR).
2. Supervised therapy vs coached home program. For uncomplicated fractures the best available evidence finds no consistent benefit of routine formal physiotherapy over a well-instructed home program; supervision is best targeted to stiffness, oedema, CRPS risk or slow progress. Moderate (SRs/RCTs), but heterogeneous.
3. Strengthening and return-to-load timing. The week-by-week strengthening ramp and the 12-week loading hold are construct- and biology-based consensus, drawn from surgeon/hand- therapy protocols rather than a strengthening-timing RCT. Weak/consensus.
4. Whether the wrist needs any immobilisation at all. Some trials report that omitting post-op immobilisation does not worsen outcomes after volar plating, supporting the "splint for comfort only" stance here. Moderate.

D. EVIDENCE STRENGTH FLAGS (summary)

• STRONG / MODERATE–STRONG (RCT / SR): early wrist motion after volar plating is safe and improves short-term ROM/grip/comfort without loss of reduction (accelerated-rehab RCT JBJS 2014; early-vs-late RCT HAND 2018; Hand Therapy SR 2020); ~2-wk vs ~6-wk mobilisation equivalent by 3–6 months (Lozano-Calderón JBJS 2008).
• MODERATE: volar locking plate is a reliable fixed-angle construct with equivalent/favourable outcomes vs alternatives (JAAOS 2014; Hand Clinics 2021); operative-vs-conservative outcomes converge in the elderly (BMC 2022); coached home program ≈ supervised therapy for uncomplicated cases (J Hand Ther 2014; J Physiother 2017; Hand Clinics 2021); evidence-based oedema management (J Hand Ther 2017).
• WEAK / CONSENSUS: the detailed strengthening ramp and 12-week loading limit (surgeon & hand-therapy protocols; biology- and construct-based, not trial-derived); scar/tendon-glide massage practice.
