Overview

A proximal humerus fracture is a break near the top of your upper arm bone (humerus), right where it meets your shoulder socket. It's one of the most common fractures in older adults, usually after a simple fall onto an outstretched arm or the shoulder. Most people, especially those with less displaced fractures, recover well with non-surgical treatment (OrthoInfo).

What Is It?

The top of your humerus (upper arm bone) is the rounded "ball" that sits in your shoulder socket, with two bony bumps nearby — the greater and lesser tuberosities — where your rotator cuff tendons attach. A fracture here means this area has cracked or broken, sometimes in one simple line, sometimes in several pieces.

Fractures are often described by how many separate bone fragments are involved — from a simple, minimally shifted break to a more complex fracture with the head, both tuberosities, and the shaft all separated from one another.

Anatomy Involved

The fracture site sits right where the rotator cuff tendons attach and where the axillary nerve wraps closely around the bone. This is why clinicians check both rotator cuff function and nerve sensation carefully after this injury.

What This Structure Normally Does

The top of the humerus forms the "ball" half of your shoulder's ball-and-socket joint and provides the attachment points for your rotator cuff muscles. A fracture here disrupts both the joint surface itself and the leverage your rotator cuff needs to move and stabilize your arm.

Common Causes

A fall onto an outstretched arm, by far the most common cause in older adults
A direct blow or fall onto the shoulder
A motor vehicle collision or other high-force trauma, more often the cause in younger people
Osteoporosis, which weakens bone and makes fractures more likely from relatively minor falls

Most proximal humerus fractures in older adults happen from a simple fall from standing height, often related to reduced bone density. In younger people, it usually takes significantly more force, such as a car accident or a hard fall from height (Johns Hopkins Medicine).

Risk Factors

Age over 60, with risk rising steadily with age
Osteoporosis or reduced bone density
Female sex — this fracture is more common in women than men
Conditions or medications that increase fall risk, such as poor balance or vision problems
Previous fracture from a low-impact fall

Common Symptoms

Significant pain at the shoulder and upper arm, often severe
Marked swelling and bruising, sometimes tracking down the upper arm
Very limited or painful shoulder movement
Visible deformity in more severe or displaced fractures
Numbness over the outer shoulder or weakness lifting the arm out to the side, which can suggest nerve involvement

Seek immediate medical care if: you suspect a shoulder fracture after a fall or collision. This needs prompt evaluation with X-rays. Seek emergency care especially if there's numbness, a pale or cold hand, loss of pulse, or an open wound near the fracture — these can indicate nerve, blood vessel, or skin involvement needing urgent attention.

Pain Location

Pain is usually felt throughout the shoulder and upper arm, often severe immediately after the injury. It's typically worse with any attempt to move the arm and can extend partway down toward the elbow.

Pain Pattern

Pain is sudden and often intense at the time of the fall or injury, staying sharp with movement for the first days to weeks. It gradually eases as the bone begins to heal, though some discomfort with specific movements can persist for months, especially with more complex fractures.

Movements That Commonly Hurt

Any lifting of the arm, especially away from the body
Reaching forward or overhead
Rotating the arm inward or outward
Bearing any weight through the arm, such as pushing up from a chair
Sudden or jarring movements of the shoulder

Activities That Become Difficult

Dressing, especially pulling on sleeves
Washing or brushing hair
Carrying bags, groceries, or other everyday items
Driving
Sleeping comfortably in most positions

Common Misconceptions

"A broken shoulder always needs surgery." Most proximal humerus fractures, especially in older adults with minimal displacement, are treated successfully without surgery (Physiopedia).
"I should keep my whole arm completely still until it's fully healed." Early, gentle motion — such as pendulum exercises — is often introduced within the first couple of weeks to help prevent stiffness, guided by your care team.
"This means I'll never get full use of my shoulder again." Many people, especially with less severe fractures treated appropriately, regain very good functional use, though recovery can take several months.
"Older age means a worse outcome no matter what." While healing can take longer in older adults, appropriate treatment and consistent rehabilitation lead to good outcomes for most people.

What Usually Makes It Worse

Bearing weight through the arm before the fracture has adequately healed
Skipping follow-up X-rays that confirm healing progress
Prolonged, complete immobilization beyond what's recommended, which can cause significant stiffness
Falls or re-injury during the healing period

What Usually Makes It Better

Following the sling or immobilization protocol recommended by your surgeon or physiotherapist
Starting gentle, guided motion at the appropriate stage to prevent stiffness
Structured, progressive rehabilitation once healing allows
Addressing underlying bone health (such as osteoporosis) with your physician

Self-Care Options

Use the sling or immobilizer as directed, especially in the first few weeks
Ice for 15–20 minutes at a time to help with pain and swelling
Over-the-counter pain medication if appropriate for you
Gentle hand and wrist movement to maintain circulation while the shoulder rests
Sleeping propped up or with extra pillow support if lying flat is uncomfortable

Conservative Treatment

Sling or shoulder immobilizer, typically for the first couple of weeks
Early passive, pain-free range-of-motion exercises such as pendulum exercises, introduced gradually under guidance
Regular follow-up X-rays to confirm the fracture is healing in good alignment
Physiotherapy progressing from passive to active motion, then strengthening, as healing allows

Most proximal humerus fractures that are minimally displaced are treated successfully without surgery, particularly in older adults (Physiopedia).

Medical Treatment Options

X-ray imaging to confirm the fracture pattern; CT scan sometimes used for more complex fractures
Closed reduction (realigning the bone without surgery) in select cases
Surgical fixation with plates, screws, or pins for significantly displaced fractures
Shoulder replacement (including reverse shoulder replacement) for severe, multi-fragment fractures, particularly in older adults with poor bone quality

Recovery Timeline

Recovery often takes about 3 to 4 months for the bone itself to heal, though continued improvement in strength and comfort can continue for up to a year, especially after more complex fractures or surgery (Orthopaedic Trauma Association). Rehabilitation typically starts with gentle passive motion in the first weeks and gradually progresses to active strengthening over subsequent months.

Returning to Work

Desk-based work may be possible within days to a couple of weeks with the arm supported, depending on comfort. Manual labor or jobs requiring lifting or overhead work generally need a much longer, graded return — often several months — guided by healing on X-ray and functional strength.

Returning to Sport

Return to sport is gradual and depends heavily on fracture severity and treatment type. Light activity may resume once early healing is confirmed, but contact sports or activities with a fall risk are usually delayed until the bone has substantially healed and strength has been rebuilt, often 4-6 months or more.

Possible Complications

Stiffness or reduced range of motion, particularly if motion isn't reintroduced appropriately
Avascular necrosis (loss of blood supply to the humeral head), more likely with certain fracture patterns
Nonunion or malunion of the fracture
Axillary nerve injury, causing numbness or deltoid weakness
Rotator cuff dysfunction if the tuberosities don't heal in good position
Post-surgical risks such as infection or hardware-related irritation

Prevention

Addressing fall risk factors — such as improving balance, vision, and home safety — along with supporting bone health through appropriate nutrition, activity, and medical management of osteoporosis, can help reduce risk, especially in older adults. See General Shoulder Health and Posture for related guidance on shoulder resilience.

Frequently Asked Questions

Will I need surgery for a proximal humerus fracture? Not always. Many fractures, especially those with little displacement, are treated successfully without surgery, particularly in older adults with lower activity demands.

How long until I can use my arm normally again? This varies widely by fracture severity, but many people see steady improvement over 3 to 4 months, with continued gains in strength for up to a year in some cases.

Is this the same as a shoulder dislocation? No. A fracture is a break in the bone itself, while a shoulder dislocation is when the joint surfaces separate without necessarily breaking a bone. The two can sometimes occur together.

Why does my doctor keep ordering X-rays? Regular X-rays confirm the fracture is healing in good alignment and help guide when it's safe to progress your activity and rehabilitation.

Will I need a shoulder replacement? Most people don't. Replacement is generally reserved for severe, multi-fragment fractures or cases where the bone's blood supply is significantly compromised, particularly in older adults with lower-quality bone.

Can I move my arm at all while it's healing? Often yes, in a guided way. Gentle, pain-free passive motion is frequently introduced early to help prevent stiffness, with the specific timing depending on your fracture pattern and treatment.
