You can start gentle physiotherapy within days of a fracture, often while the limb is still immobilized, and full active rehabilitation typically begins around 6 weeks once your doctor or orthopedic surgeon confirms initial bone healing and clears removal of the cast or brace. After surgical fixation, mobilization frequently begins sooner, sometimes within 24 to 48 hours. Below we cover what bone healing actually does across those weeks, why controlled movement supports the process rather than threatening it, what treatment is available while a cast is still on, how timelines shift by fracture site, and what the evidence shows about the cost of waiting.

When Can You Start Physiotherapy After a Fracture?

You can start physiotherapy after a fracture within days for gentle work, and around 6 weeks for full active rehabilitation, with the exact timing set by your fracture type, whether you had surgery, and your surgeon’s clearance. Two separate starting lines exist here, and conflating them is the most common source of confusion. Early physiotherapy during immobilization manages pain and swelling, protects the joints above and below the injury, and maintains conditioning, while active rehabilitation of the fractured segment itself waits for confirmed bone healing.

Confirmed healing is the surgeon’s call, not the physiotherapist’s, and that division of responsibility matters. Our fracture physiotherapy plans are built around the surgeon’s protocol rather than alongside it, which means we work to the restrictions you have been given and progress only as those restrictions lift. Patients arriving at our Markham clinic directly from an orthopedic follow-up usually bring a weight-bearing status and a movement restriction, and those two pieces of information shape everything we do next.

What the restrictions are protecting becomes much clearer once you know what the bone is doing underneath the cast.

What Are the Stages of Fracture Healing?

The stages of fracture healing are the inflammatory phase, the reparative phase covering soft callus and then hard callus formation, and the remodelling phase. These three overlap rather than running in sequence, which is why the boundaries between them are described as approximate ranges rather than fixed dates. Bone begins repairing itself immediately, and new bone formation becomes visible on radiographs within 7 to 10 days of injury according to fracture education guidance from the Royal Children’s Hospital.

Visible on a radiograph is not the same as strong enough to use, and the table below maps that distinction across the whole timeline.

Stage	Typical timeframe	What the tissue is like	What physiotherapy does
Inflammatory	Hours to days	Haematoma forms at the fracture site, releasing the cytokines and growth factors that begin repair	Pain and swelling management, positioning, education, gentle work on adjacent joints
Soft callus	Around day 5 through 2 to 3 weeks; soft callus first appears around day 12	Plastic and deformable; bends easily if the fracture is not adequately supported	Protected motion only, adjacent joint mobility, general conditioning, assistive device training
Hard callus	Roughly weeks 2 to 12, commonly ending 6 to 12 weeks post-fracture	Woven bone, weaker than mature bone but able to withstand external force; corresponds to clinical union	Progressive range of motion, graded loading, early strengthening as clearance allows
Remodelling	Roughly 8 weeks to 2 years	Woven bone converted to mature, organized bone that adapts to the loads placed on it	Progressive strengthening, functional and balance training, return to sport and work

Remodelling is the stage most people never hear about, and it explains why a bone that feels fine at three months keeps improving for a year or more. Bone laid down during remodelling responds directly to activity, external forces, and functional demand, which is the biological reason a rehabilitation programme continues past the point where the fracture stops hurting.

What Is Clinical Union in a Fracture?

Clinical union is the point at which a fracture is no longer tender to palpation or with movement, corresponding to the formation of hard callus. It is a clinical finding rather than a radiographic one, meaning your clinician can identify it by examining you. Clinical union does not mean the bone has returned to full strength, since hard callus is still weaker than mature bone. It does mean the fracture has become stable enough for external supports to come off and for loading to progress.

Can a Fracture Take 2 Weeks to Heal?

No, a fracture cannot fully heal in 2 weeks in an adult, though pain often improves substantially by then. At the two-week mark the soft callus is still forming and remains plastic enough to deform under load. Bone union generally occurs around 4 to 6 weeks as a broad guide, with hard callus continuing to mature for 6 to 12 weeks after that. Feeling better at two weeks reflects settling inflammation rather than a healed bone, which is precisely why restrictions stay in place while comfort returns.

Does Movement Help Bones Heal Faster?

Yes, appropriate movement helps bones heal, because mechanical loading within physiological limits acts as an anabolic stimulus for bone healing rather than as a threat to it. This is the part of fracture recovery that gets explained least often and matters most. Bone is living tissue that responds to the forces placed on it, and controlled loading signals the cells laying down new bone to work harder and to organize that bone along the lines of stress it will actually face.

Stress along realistic lines is what produces functional bone rather than merely present bone. The same principle appears in the reparative phase itself, where a degree of motion at the fracture site stimulates callus formation. Research summarised in orthopedic literature notes that greater fracture mobility produces greater callus, which is the opposite of the intuition most people bring to a broken bone.

The distinction that matters is between controlled loading within prescribed limits, which drives healing, and uncontrolled loading beyond those limits, which disrupts it. Everything a physiotherapist does after a fracture sits on that line. Immobilization protects the fracture from the second category while unavoidably withholding the first, which is why periods of immobilization are clinically associated with joint stiffness and muscle weakness, and why reducing them where safe has become a research priority.

Reducing them safely starts with what can be treated while the cast is still on.

Can You Do Physiotherapy While Still in a Cast?

Yes, you can do physiotherapy while still in a cast, and this early phase is where a lot of avoidable loss gets prevented. Treatment during immobilization leaves the fracture site alone entirely and works on everything around it. The fractured bone needs protection; your shoulder, your other leg, and your cardiovascular conditioning do not.

A during-immobilization programme typically covers:

1. Pain and swelling management, including elevation strategy, positioning, and safe use of ice.
2. Range of motion for every unblocked joint, so a wrist cast means we work the fingers, elbow, and shoulder.
3. Isometric muscle activation inside the cast where cleared, which maintains neural drive to muscles that cannot move the joint.
4. Training on crutches, walkers, or slings, covering stairs, getting in and out of a vehicle, and standing from a seated position safely.
5. Conditioning for the rest of the body, so the uninjured limbs and cardiovascular system do not decondition over six weeks.
6. Education on your weight-bearing status and what it actually permits in daily life.
7. A home programme, since the majority of this work happens between appointments rather than in them.

Between appointments is where the programme either holds or lapses, and exercise rehabilitation is built with that reality in mind rather than assuming clinic time alone will carry the recovery. Doing this work early is worth the effort because of what happens to muscle when nothing is done at all.

What Exercises Can I Do With a Broken Arm?

With a broken arm you can do finger and thumb movements, shoulder range of motion, elbow motion where the cast allows, isometric contractions inside the cast where cleared, and full lower body and cardiovascular conditioning. Finger swelling and stiffness after a forearm or wrist cast is one of the most common avoidable complications, and regular finger movement through the day largely prevents it. Confirm which joints are cleared to move before starting, since the answer depends on where the cast ends.

Why Do Muscles Get Weak After a Fracture?

Muscles get weak after a fracture because immobilization removes the mechanical load that maintains muscle mass, and the loss begins within days rather than weeks. Muscle tissue is expensive for the body to maintain, so unused muscle is broken down quickly. The joint stiffens alongside it as soft tissues shorten and joint surfaces stop gliding through their full range.

The scale of that loss has been measured. A randomized trial comparing 4-week and 6-week cast immobilization in elderly patients with distal radius fractures found mean grip strength in the treated limb reaching 71% of the healthy limb in the 4-week group and 81% in the 6-week group. Mean wrist flexion measured 62 degrees against 75 degrees between the same groups. Notably, neither group achieved symmetry of strength or range of motion by the end of treatment.

Neither group reaching symmetry is the finding worth sitting with, because it shows that the deficit after a fracture is real, measurable, and does not simply resolve on its own once the cast comes off. Soft tissue work has a role here too, and massage therapy helps address the tightness and circulatory sluggishness that build up in a limb held still for weeks.

What Does Physiotherapy Protect After a Fracture?

Physiotherapy after a fracture protects your range of motion, your muscle strength, your balance and confidence, and your ability to return to the activities you did before the injury. Bone healing happens whether or not you attend rehabilitation. What rehabilitation determines is the state of everything around the bone at the point when the bone is finally ready to be used.

Ready to be used is where the gap opens between people who rehabilitated and people who waited. A fracture that unites perfectly on imaging can still leave a joint that will not bend far enough to reach a shelf, a limb too weak to trust on stairs, and a balance system that has not stood on that leg in eight weeks. Older adults face an added consideration, since a period of reduced mobility raises falls risk at exactly the point when confidence is lowest. Structured physiotherapy addresses all three deficits deliberately rather than hoping they resolve with time.

How much of that work is needed depends partly on how the fracture was managed in the first place.

Do You Need Physiotherapy After a Fracture If You Had Surgery?

Yes, you need physiotherapy after a fracture that was surgically fixed, and surgical patients frequently start earlier than casted patients rather than later. The reason lies in how the two heal. Fractures held rigidly by plates and screws heal largely through primary bone healing, where there is minimal movement at the fracture site and consequently minimal callus formation. Fractures managed in a cast heal through secondary bone healing, where some movement occurs and visible callus bridges the gap.

Callus, or its absence, changes the clinical picture in a way most people find counterintuitive. Rigid internal fixation means the fracture is mechanically stable from the moment surgery finishes, which is why mobilization after surgery often begins within 24 to 48 hours. Surgery also adds its own rehabilitation demands, including soft tissue healing around the incision, scar management, and in some joints a real risk of stiffness that early motion is specifically intended to prevent. Post-surgical rehabilitation at our clinic is coordinated directly with the surgeon’s protocol so the timeline matches what your surgeon intended.

What your surgeon intended also varies considerably depending on which bone broke.

How Does the Timeline Change by Fracture Site?

The timeline changes substantially by fracture site, because different bones carry different loads, heal at different rates, and sit in joints with different tolerance for stiffness. A general 6-week figure is a useful anchor and a poor plan. Typical patterns include:

• Wrist and distal radius: casting commonly 4 to 6 weeks, with finger and shoulder work starting immediately and wrist rehabilitation beginning after cast removal
• Ankle: immobilization commonly 6 to 12 weeks depending on severity, with pain, swelling, stiffness and muscle atrophy typical after the cast comes off
• Shoulder and proximal humerus: often managed in a sling with early passive and pendulum movement, since this joint stiffens readily when held still
• Elbow: among the most stiffness-prone joints, with early mobilization used specifically to reduce that risk after surgical fixation
• Hip: generally surgical, with mobilization beginning within days because the risks of prolonged bed rest outweigh the risks of early movement
• Foot and toes: variable, often managed in a boot with a staged weight-bearing progression

Progression at every one of those sites depends on the joints above and below moving properly, since a stiff ankle changes how the knee and hip load during walking. Where those compensations persist after the fracture itself has resolved, chiropractic care alongside physiotherapy helps restore the movement pattern rather than leaving the limp to become a habit.

How Long After a Wrist Fracture Can I Start Physio?

You can start physiotherapy immediately after a wrist fracture for the fingers, elbow, and shoulder, with wrist-specific rehabilitation typically starting after cast removal at 4 to 6 weeks. Starting the surrounding joints straight away matters more at the wrist than almost anywhere else, because finger stiffness and swelling develop quickly in a casted forearm and are considerably harder to reverse than to prevent.

When Can I Start Physio After a Shoulder Fracture?

You can usually start physiotherapy after a shoulder fracture within the first one to two weeks, often beginning with pendulum exercises and passive range of motion while still using a sling. The shoulder is a joint that loses motion fast when immobilized, so protocols for proximal humerus fractures frequently prioritise early gentle movement over prolonged rest. Your surgeon sets which movements are permitted and which are restricted during the early weeks.

When Can I Start Weight-Bearing After an Ankle Fracture?

You can usually start weight-bearing after an ankle fracture between 2 and 6 weeks post-surgery depending on your surgeon’s protocol, with some patients cleared for early weight-bearing as tolerated and others held non-weight-bearing for longer. Practice varies because the evidence has been actively debated, and large trials have compared early against delayed weight-bearing after operative ankle fracture treatment. Follow the status you were given rather than a timeline you read anywhere, including here.

How Do I Know If My Bone Fracture Is Healing?

You know your bone fracture is healing when pain steadily decreases, tenderness directly over the fracture site fades, swelling subsides, and you can gradually tolerate more load without a flare. Tenderness on palpation is the most useful sign you can check yourself, since the absence of tenderness at the fracture line is what defines clinical union. Radiographs confirm it, showing callus formation from as early as 7 to 10 days.

Days and weeks aside, the signs pointing the other way are worth knowing: pain that increases rather than decreases over weeks, new deformity, persistent inability to bear any load well past the expected point, or a fracture site that stays sharply tender at the stage it should be settling. Raise any of these with your surgeon rather than working around them.

Can I Walk After 4 Weeks of a Fracture?

Whether you can walk after 4 weeks of a fracture depends entirely on which bone broke and what weight-bearing status your surgeon set, and the answer ranges from full walking to no load at all. A wrist fracture places no restriction on walking whatsoever. A tibial or ankle fracture at four weeks may still be non-weight-bearing, partial weight-bearing, or weight-bearing as tolerated depending on fixation and healing.

Healing progress rather than the calendar drives the decision, and weight-bearing status is reviewed at follow-up appointments rather than assumed to advance automatically. Once walking resumes, how you load the foot matters, and custom orthotics are sometimes used where a healed lower limb fracture has altered foot mechanics enough to affect gait.

Can I Rest My Foot on the Floor When Non-Weight Bearing?

Non-weight-bearing means no weight through the limb at all, so resting your foot on the floor is only acceptable if your surgeon has specified touch weight-bearing rather than strict non-weight-bearing. The two statuses are different and are often confused. Touch or toe-touch weight-bearing permits light contact for balance, commonly described as enough pressure to squash a crisp. Strict non-weight-bearing means the foot stays off the ground entirely. Confirm which one applies to you, since the distinction changes what is safe.

What Kind of Physiotherapy Is Recommended After a Fracture?

The physiotherapy recommended after a fracture combines manual therapy for joint stiffness, progressive range of motion work, graded strengthening, balance and proprioception training, gait retraining for lower limb fractures, and functional practice matched to your work and activity demands. The mix shifts as you progress, with early sessions weighted toward restoring movement and later sessions weighted toward building capacity.

Capacity building is the phase people most often cut short, because it starts after the pain has gone. Adjuncts support the process where specific barriers appear, and laser therapy is used where persistent inflammation is limiting how much movement a joint will tolerate.

Tolerance for movement is also limited by the muscle guarding that builds up around a limb protected for weeks, and acupuncture reduces that guarding so the active programme can progress.

Progressing an active programme after a bone injury sits within a defined area of practice covering fractures, joint replacements, and post-surgical recovery, which is what orthopaedic physiotherapy is built around.

How Many Physiotherapy Sessions Will You Need After a Fracture?

You will typically need 8 to 20 physiotherapy sessions after a fracture, spread across 8 to 16 weeks, with simple wrist fractures at the lower end and complex lower limb or intra-articular fractures at the higher end. Frequency usually starts weekly or twice weekly after immobilization ends, then tapers as your home programme takes over the majority of the work.

Taking over the work is the goal rather than a compromise, since the loading that drives remodelling happens across the whole week rather than in a treatment room. Our physiotherapists re-measure range of motion and strength at set intervals so progression is based on numbers rather than impressions, and patients across Markham and York Region are discharged against those measurements rather than against a session count.

Session counts aside, a fracture rarely affects only the bone that broke, and weeks of altered movement leave their mark on the joints that compensated. Multidisciplinary care keeps those knock-on effects addressed within the same plan rather than as a separate problem later.

How to Protect Your Recovery Between Appointments

Protect your recovery between appointments by completing your home programme daily, respecting your weight-bearing status exactly, keeping the unaffected joints moving, and supporting bone healing through adequate nutrition and sleep. Consistency does more than intensity here. A short programme performed daily produces better outcomes than a long one performed twice a week.

Weekly performance aside, a few specifics carry disproportionate weight. Elevate a swollen limb above heart level rather than merely propping it up. Move every joint that is cleared to move, several times a day, rather than once. Keep protein, calcium, and vitamin D intake adequate, since bone repair is a construction project that needs materials. Avoid smoking, which measurably impairs bone healing. Where something feels wrong, raise it at the next appointment rather than adjusting your programme on your own, since our patients in Markham who flag changes early tend to resolve them in one session rather than three.

Frequently Asked Questions

How Many Days of Rest Are Required After a Fracture?

Complete rest after a fracture is required for days rather than weeks, and prolonged rest is generally avoided because it costs muscle strength and joint mobility without benefiting the bone. The fractured segment stays protected for as long as your surgeon specifies, but the rest of your body should stay active throughout. Bed rest in particular carries risks that outweigh its benefits for most fractures.

I Took Off My Walking Boot Too Early, What Should I Do?

If you took off your walking boot too early, put it back on and contact your surgeon or fracture clinic for advice rather than waiting for your next scheduled appointment. A short period out of the boot without significant loading is usually not a problem, though the assessment belongs to your treating team. Note what you did, how long for, and whether pain or swelling changed afterward, since those details help them judge whether imaging is warranted.

How Long Does Stiffness Last After a Cast Comes Off?

Stiffness after a cast comes off usually improves substantially over 4 to 8 weeks with active rehabilitation, though the joint may not reach full symmetry with the uninjured side for several months. Trial data in distal radius fractures found that neither 4-week nor 6-week casting groups achieved symmetry of range of motion by the end of treatment, which reflects how much of the recovery happens during rehabilitation rather than during immobilization.

Is It Normal for a Healed Fracture to Still Ache?

Yes, it is normal for a healed fracture to still ache occasionally, particularly with weather changes, heavy activity, or at the end of a long day, and this can continue for months into the remodelling phase. Remodelling runs from roughly 8 weeks out to 2 years, so the site remains biologically active well after it is functionally recovered. Aching that is worsening rather than gradually settling is worth reporting.

Do I Need a Referral for Physiotherapy After a Fracture in Ontario?

No, you do not need a referral for physiotherapy after a fracture in Ontario, since physiotherapists are primary care practitioners you can book directly. Bring your imaging reports, your weight-bearing status, and any written restrictions from your surgeon to the first appointment. Some extended health plans require a referral for reimbursement even though the clinic does not, so check your policy.

Can Physiotherapy Start Before I See My Surgeon Again?

Yes, physiotherapy can start before your next surgeon appointment, provided treatment stays within the restrictions you have already been given. Early work on adjacent joints, swelling management, assistive device training, and general conditioning requires no additional clearance in most cases. Anything involving the fractured segment itself waits until your surgeon confirms the next stage.

What It All Comes Down To

Physiotherapy after a fracture starts far earlier than most people expect. Gentle work begins within days, often while a cast is still on, and full active rehabilitation follows at around 6 weeks once your surgeon confirms the bone has healed enough to load. The reason for starting early is not impatience. Mechanical loading within safe limits actively stimulates bone healing, while immobilization reliably costs strength and range of motion that has to be rebuilt afterward.

Rebuilding is where the real work sits, and the measured evidence is clear that the deficit after a fracture does not resolve on its own once the cast comes off. If you have broken a bone recently, or you are out of your cast and finding the limb weaker and stiffer than you expected, we are glad to assess where you stand and build a plan that works to your surgeon’s protocol. You can book an assessment with our team, and everything at KC Rehab stays coordinated under one roof from the first week through to full return to activity.
