A humerus fracture is a break in the upper arm bone. Recovery depends on the fracture type, bone position, treatment plan, and movement limits. Humeral fracture physical therapy helps restore safe shoulder and arm movement. It reduces stiffness, rebuilds strength, and supports a return to daily activities.
At ITNYCPT in New York City, humeral fracture rehab includes one-on-one physical therapy. It also includes personalized exercise plans and close attention to medical restrictions.

This guide explains when rehab may start, which exercises may be used, and how recovery may differ after surgery or nonoperative treatment.
Key Takeaways
- Humeral fracture physical therapy helps restore shoulder and arm movement after the bone is stable enough for safe rehab.
- Recovery often moves from protected motion to assisted movement, active motion, and strengthening over several months.
- Exercises may include hand, wrist, and elbow motion, pendulums, table slides, wall walks, isometrics, and later resistance work.
- Rehab timelines vary based on fracture type, surgery status, fracture displacement, pain, age, and medical restrictions.
- Sharp pain, new numbness, worsening swelling, sudden weakness, or a change in color of the hand should prompt medical follow-up.
Does Physical Therapy Help Humerus Fractures?
Yes. Physical therapy can help improve motion, strength, comfort, and function after a humerus fracture. It does not heal the bone directly, but it can help the shoulder, elbow, wrist, and hand move better as the bone heals.
The plan depends on the fracture pattern, fracture displacement, pain level, and medical restrictions. Some people start gentle motion early, while others need more time in a shoulder immobilizer before moving the arm.
What Is a Humeral Fracture?
A humeral fracture is a break in the humerus, the long bone between the shoulder and elbow. The type of fracture matters because a break near the humeral head can affect the shoulder joint and rotator cuff, while a midshaft fracture can affect arm strength and sometimes nerve function.
A physical therapy evaluation may include a review of symptoms, imaging instructions, movement limits, strength, pain, sleep position, and daily goals. This helps the therapist create a plan that matches the injury and the person’s needs.
Common Fracture Types
A proximal humerus fracture happens near the shoulder. Proximal humerus fracture treatment may include sling use, nonoperative treatment, or surgery if the fracture is displaced or unstable.
A midshaft humerus fracture happens in the middle of the upper arm. Some shaft fractures may involve a nerve injury, which can affect wrist, hand, or grip control.
A more complex part fracture may involve several bone pieces. Fracture dislocations, avascular necrosis, and severe fracture displacement may require closer medical management because they can affect long-term functional outcomes and quality of life.
When to Start Physical Therapy After a Humerus Fracture
The start date depends on healing, imaging, pain, surgery status, and medical instructions. Some minimally displaced fractures allow earlier gentle movement, while other injuries need longer protection.
After nonoperative treatment, early rehab may focus on the hand, wrist, elbow, and gentle shoulder motion. After surgery, including open reduction and internal fixation, post-surgery rehabilitation exercises should follow the surgeon’s protocol.
Movement may be limited at first. For example, the person may not be allowed to lift, push, pull, or externally rotate the shoulder past a set range.
What Physical Therapy Do You Need?
Physical therapy after a humerus fracture may include education, protected movement, range-of-motion work, strengthening, manual therapy when appropriate, and home exercise carryover. Early care focuses on protecting the fracture, while later care helps rebuild movement, strength, and daily function.
Soft tissue work may be used later if muscle tightness, scar sensitivity, or shoulder stiffness limit movement, especially when nearby shoulder structures need careful loading.
Similar principles may apply in SLAP tear physical therapy treatment, where rehab also considers shoulder control, tissue tolerance, and gradual strengthening. Pilates-based therapeutic exercise may support trunk control, shoulder positioning, mobility, and return to activity when it fits the stage of rehab.
Humerus Fracture Physical Therapy Exercises
Humerus fracture physical therapy exercises should match the healing phase, medical restrictions, pain level, and bone stability. Exercises for fractured humerus recovery are not the same for every person, and the best exercise for a fractured humerus depends on timing.
Early exercises usually protect motion, while later exercises build active movement, rotator cuff strength, and daily function. A safe program usually progresses from gentle motion to assisted movement, then active motion and strengthening.
Common exercise categories include:
- Hand, wrist, and elbow motion to reduce stiffness
- Pendulum exercises for gentle shoulder movement
- Assisted shoulder motion with the other arm, a cane, or a table
- Isometric exercises to activate muscles with little joint movement
- Strengthening exercises with bands or light resistance when cleared
Pendulum Exercises
Pendulum exercises are often used early when shoulder motion is limited. The person leans forward, lets the arm hang, and uses body movement to create small circles or forward-back motion.
The arm should stay relaxed. The movement should feel mild, not sharp or forced.
Assisted Shoulder Motion
Assisted motion helps the injured arm move with support. This may include table slides, wall walks, cane-assisted lifting, or using the other arm to guide the movement.
The goal is to restore range without forcing the shoulder. If the shoulder hikes, pinches, or causes sharp pain, the movement may need to be reduced.
Isometric Strength Exercises
Isometric exercises tighten a muscle without moving the joint much. A person may gently press the hand against a wall or the other hand to engage the shoulder muscles.
These exercises can help maintain muscle activity while the fracture continues to heal. They should stay light until the person is cleared for more resistance.
Active Motion Exercises
Active movement starts when the person can move the arm without help. This may include forward reaching, shoulder elevation, controlled rotation, and light functional tasks.
The therapist watches how the shoulder moves. If the person leans the trunk, shrugs the shoulder, or guards the arm, the exercise may need adjustment.
Strengthening Exercises
Strengthening begins when the bone can tolerate load. Exercises may target the rotator cuff, shoulder blade muscles, upper arm, grip, and trunk.
Resistance should increase slowly. Too much load too soon can increase pain, especially if the fracture is still healing or the shoulder remains stiff.
Broken Humerus Rehabilitation Exercises by Timeline
Broken humerus rehabilitation exercises often follow a phased timeline, but the timing must match medical restrictions and bone healing. In early recovery, exercises usually focus on keeping nearby joints moving while the shoulder stays protected.
This may include hand squeezes, wrist circles, elbow bending, gentle pendulums, and posture work. These movements help reduce stiffness without placing heavy stress on the healing bone.
At about 6 to 12 weeks, many people begin more active shoulder work if the fracture is healing well. Exercises may include table slides, wall walks, cane-assisted shoulder flexion, and gentle external rotation within the allowed range.
These exercises help restore shoulder motion before heavier strengthening begins. The goal is controlled movement, not maximum range.
About 3 months after a proximal humerus fracture, exercises often shift toward light strengthening and improved shoulder control. This may include resistance band rows, light rotator cuff exercises, scapular squeezes, wall slides, and controlled reaching.
The goal is to improve daily use, such as dressing, reaching a shelf, or carrying light objects. If pain increases or movement quality declines, the exercise may need to be performed at a lower level.
At 6 months after a proximal humerus fracture, rehab may focus on higher-level strength, endurance, overhead tolerance, and return to work or exercise goals. Exercises may include progressive resistance training, overhead control drills, loaded carries, and task-specific practice.
Some people still have stiffness or weakness at this stage, especially after surgery or a complex fracture. Ongoing rehab may focus on the specific movements that remain limited.
Rehab Protocols by Fracture Type
A rehab protocol changes based on fracture location and treatment type. A proximal humerus fracture rehab protocol for nonoperative treatment often emphasizes initial sling protection, followed by assisted shoulder motion, active motion, and light strengthening.
After surgery, a proximal humerus fracture physiotherapy protocol may move more slowly if hardware, soft-tissue repair, or joint involvement needs protection. If a fragment displaces proximally or the fracture becomes unstable, the medical plan may change.
A midshaft humerus fracture rehabilitation protocol often focuses on brace tolerance, elbow range of motion, shoulder stiffness, grip strength, wrist motion, and nerve symptoms. The therapist may also monitor sensory changes if nerve irritation is part of the injury.
How Long Does Recovery Take?
Recovery after a humerus fracture often takes 3 to 6 months, but complex injuries can take longer.
For more general rehab timelines, this guide on how long physical therapy takes explains why progress varies depending on the injury, goals, and response to treatment. Many people regain basic daily function before they regain full shoulder strength, overhead reach, or confidence using the arm.
Recovery may take longer after surgery, significant fracture displacement, fracture-dislocation, nerve injury, risk of avascular necrosis, or a complex part fracture. An elderly patient may also need more time because factors such as bone health, balance, strength, and medical history can affect recovery.
Safe recovery comes from steady progress, not rushing. More exercise is not always better if the bone, joint, rotator cuff, or soft tissues are not ready for increased load.
What Not to Do With a Broken Humerus
A broken humerus needs protection while it heals. The biggest mistakes are lifting too soon, forcing painful motion, ignoring restrictions, or stopping all movement without guidance.
Avoid these unless cleared by your medical provider:
- Lifting, pushing, pulling, or weight-bearing through the injured arm
- Forcing the shoulder into sharp pain
- Moving beyond surgical restrictions
- Removing the shoulder immobilizer earlier than instructed
- Ignoring new numbness, tingling, swelling, or weakness
Some soreness can happen during rehab, but sharp pain or sudden loss of function is different. The plan should be adjusted if symptoms do not align with the expected recovery.
When Should You Seek Medical Care?
Seek medical care after a fall, visible deformity, severe pain, major swelling, color change in the hand, numbness, or inability to move the arm. These signs may point to a fracture, dislocation, nerve issue, or circulation problem.
During rehab, you may need medical follow-up for sudden pain increases, new weakness, or fever after surgery. You may also need follow-up for worsening swelling, or new numbness and tingling.
A physical therapist can help you know if symptoms are normal during rehab or need a doctor’s review. When symptoms fall outside the expected pattern, medical follow-up is safer.
What to Expect in NYC Physical Therapy
In New York City outpatient physical therapy, a visit often starts with a review of the diagnosis, restrictions, symptoms, goals, and daily movement problems. The therapist may assess the shoulder, elbow, wrist, hand, neck, posture, and movement quality.
An individualized plan of care should change over time. The home exercise program should also progress so that the work between visits supports improved mobility, strength, and daily use.
