A full-thickness supraspinatus tear means the tendon is split all the way through, often leaving a gap where it attaches to the arm bone.
Your shoulder lifts and reaches through a group of four tendons called the rotator cuff. The supraspinatus sits on top of that group and starts most overhead moves. When this tendon tears all the way through, strength drops, overhead motion feels weak, and sleep can turn sore. This page explains what that tear actually is, how doctors find it, and which treatments restore comfort and function.
What Is A Full Thickness Tear Of The Supraspinatus Tendon
A full-thickness tear means the split runs from the upper surface of the tendon to the joint surface. In many people the inner edge pulls back from the humerus, creating a “hole” in the tissue. Partial tears fray only one surface; a full tear crosses the entire tissue. The supraspinatus is the most common place for this type of rotator cuff injury.
In simple terms, the tendon that lifts your arm no longer forms a continuous band. Your body still recruits nearby muscles, so some motion stays possible, yet the smooth “lift” fades. Pain can be sharp with reaching, or a dull night ache along the upper arm. Weakness is common when trying to raise the arm away from the body or hold it up.
Full-Thickness Supraspinatus Tear: Meaning & Next Steps
Think of the injury on two axes: size and symptoms. Size ranges from small (under 1 cm) to massive (over 5 cm or involving multiple cuff tendons). Symptoms range from mild soreness with certain tasks to clear loss of strength and limited motion. Care starts with pain control and targeted exercises; surgery is reserved for specific tear patterns, failed rehab, or high-demand needs.
Tear Types At A Glance
| Tear Type | What It Means | Common Signs |
|---|---|---|
| Partial-thickness | Fraying on one surface; fibers still span the gap. | Pain with reach; near-normal strength. |
| Full-thickness | Split through the entire tendon; may retract from bone. | Weak lift; night ache; painful arc. |
| Massive/multi-tendon | Large defect or more than one cuff tendon involved. | Marked weakness; limited motion. |
Why This Tear Happens
Two paths lead here. One is a single event, such as a fall on the side of the arm or lifting a heavy object with the elbow straight. The other is slow wear from years of overhead work or sport. Bone spurs on the acromion can rub on the tendon. Blood supply to the cuff also thins with age, which makes the tissue less resilient. Tobacco, diabetes, and high cholesterol link with poorer tendon quality and slower healing.
Risk rises after midlife, yet younger overhead athletes can face it after repeated spikes or serves. Prior partial tears can progress to a complete split. Family history and posture issues play a part. Heavy repetitive tasks at work place extra load on the cuff, especially when arms are lifted away from the body.
Symptoms You May Notice
Pain settles on the upper outer arm and can track to the elbow. Reaching to a high shelf, putting on a coat, or combing hair may sting. The arm can feel weak or “giving way” when holding items at shoulder height. Sleep on the injured side often hurts; a pillow under the arm sometimes eases the ache. Popping or creaking can appear during motion; stiffness often builds from guarding the shoulder.
When To Seek Care
Book an appointment soon if pain lasts beyond a couple of weeks, if arm strength falls off, or if the injury follows a fall. Seek urgent care if you cannot raise the arm at all after trauma, if numbness spreads below the elbow, or if swelling and warmth suggest infection after an injection or surgery. Early evaluation helps set a plan and reduces the chance of long-term stiffness.
Diagnosis: Exam And Imaging
An experienced clinician checks posture, range, and strength. Painful arc tests and resisted “empty-can” positioning stress the supraspinatus. A careful neck exam rules out referred pain. Plain X-rays show bone spurs or arthritis. Ultrasound can show a gap in the tendon and works well in trained hands. MRI details tear size, retraction, and any muscle fatty change.

Imaging Details: What MRI And Ultrasound Show
Ultrasound gives a real-time view while you move. A full-thickness gap looks like a black cleft where the tendon should bridge to the humerus. The examiner can watch the cuff slide under the acromion and can note pinching as the arm lifts. Ultrasound can also spot fluid and bursal swelling that often ride along with a painful tear.
MRI maps the tear in three planes. Reports describe width (front-to-back), retraction (how far the edge pulls from the footprint), and any fatty change in the muscle belly. Retraction and fatty change matter because they tie to how well a repair is likely to hold and how strong the shoulder may be after rehab. MRI also shows other issues like biceps tendon trouble or arthritis that could steer the plan.
Who May Choose Surgery Sooner
People with an acute tear after a fall who cannot lift the arm often land in the early-surgery group. Workers who climb, lift, or reach overhead all day may also choose a faster repair path, since their jobs expect sturdy elevation. Overhead athletes with a large full-thickness split sometimes choose repair to restore power and reduce the risk of tear growth.
Many small tears respond well to a careful nonoperative path. Steady pain control, a smart exercise plan, and activity changes can calm symptoms and build usable strength. Age, health, and tissue quality influence both choices. A thorough talk with your surgeon lays out the trade-offs: rehab time, expected strength, and the chance of retear with each route.
Treatment Overview
Plans reflect your goals, tear pattern, and shoulder condition. Many people start with nonoperative care: short rest from aggravating tasks, ice or heat for comfort, oral pain relievers, and a structured rehab plan. A steroid injection can calm inflammation for a limited time to help you move and train. Surgery reattaches the tendon to bone, often done arthroscopically through small portals. No single path fits all; the right sequence depends on symptoms, function, and activity needs.
Nonoperative Care: Build Function First
Targeted exercises train the remaining cuff and the shoulder blade muscles to share load again. Early work restores range without pinching the top of the joint. Next phases build strength in safe arcs and add endurance. Many people with small full-thickness tears gain acceptable comfort and function without surgery, especially if daily demands are modest. Set clear goals with your therapist, keep a home program, and pace activity.
Pain Control And Activity Tweaks
Short courses of acetaminophen or anti-inflammatory drugs ease soreness. Talk with your doctor about stomach, kidney, or heart risks before using anti-inflammatory drugs for more than a few days. Ice or heat helps based on preference. Swap tasks to reduce repeated overhead reach and heavy lifts away from the body. A soft pillow under the elbow at night takes strain off the tendon and often calms sleep pain.
Injections
A corticosteroid shot into the subacromial space can lower pain for weeks. This window often makes rehab easier. Repeated shots are avoided because tendon quality can suffer. Viscosupplement and biologic injections sit outside routine care here; evidence is mixed, and costs can be high.
Surgery: When And What It Involves
Surgery enters the plan when pain and weakness persist after months of good rehab, when the tear is acute and large, or when job or sport demands full overhead strength. The surgeon freshens the tendon edges and anchors them back to the humerus. Many cases use arthroscopic techniques; massive tears can need more complex methods. If the joint has advanced cuff-related arthritis, a reverse shoulder replacement may be offered instead of tendon repair.
What Recovery Looks Like After Repair
Right after surgery the arm rests in a sling to protect the repair while the tendon knits to bone. Early motion guided by the care team keeps the joint from stiffening. Strength work begins later. Full return to heavy tasks can take months. The time frame varies with tear size, tissue quality, and how closely the rehab plan is followed.
Rehab Timeline At A Glance
Rehab steps move in stages and are adjusted to the person and the tear. A common arc:
Phase 1: Settle Pain And Restore Gentle Motion (Weeks 0–6)
Therapy starts with assisted pendulums, table slides, and assisted flexion within pain limits. Scapular setting and posture drills make early motion smoother. The target is a quiet shoulder that moves through a comfortable arc without pinching.
Phase 2: Controlled Strength And Endurance (Weeks 6–12)
Isometrics advance to light bands for external rotation and scaption. Core and lower-body work keep total activity up while the shoulder rebuilds. Daily tasks return in steps: waist-level first, then chest-level, then gradual reach.
Phase 3: Higher Demand And Return To Tasks (Months 3–6)
Heavier bands and light weights enter the plan. Overhead work resumes in a graded way. Job-specific or sport-specific drills close the gap to normal life. Many people reach steady function by month four or five; heavy overhead needs can take longer.
Work And Sport: Return Benchmarks
Desk jobs often resume quickly with the arm resting at the side and breaks to move the shoulder through a gentle arc. Light manual work returns in steps as strength improves. Heavy overhead jobs wait until lifting limits clear and endurance holds through a full shift without pain spikes.
For sport, walking and stationary cycling start early. Swimming and easy ground strokes enter once strength and motion meet targets from your care team. Overhead serving, pitching, or heavy presses return late in the process with graded volume and rest days. The goal is a repeatable week of training without next-day soreness before adding load.
Table: Treatment Options And Fit
| Option | Best For | Notes |
|---|---|---|
| Rehab + pain control | Small tears; lower-demand goals | Builds strength; avoids surgery. |
| Single steroid shot | Short-term pain relief to aid rehab | Limit repeats to protect tendon. |
| Arthroscopic repair | Persistent pain/weakness or acute large tear | Reattaches tendon; rehab drives outcomes. |
Daily-Life Choices That Make Healing Easier
Space tasks that need reach. Keep items you use often between waist and chest level. Hold items close to the body when lifting. Use both hands for heavier loads. Take short breaks from overhead work. During sleep, keep a small pillow under the forearm so the shoulder rests in a neutral line.
Nutrition and general fitness help tissue health. Aim for steady protein with each meal. Stop smoking; nicotine harms tendon cells and lowers blood flow. Blood sugar control improves outcomes. Walks and light cardio keep energy up while the shoulder heals.
Possible Complications And How To Reduce Risk
Stiffness can build from guarding the arm. Gentle daily motion within pain limits keeps the joint free. A retear can happen, especially with large defects or poor tissue. Follow lifting limits and the step-wise plan from your team. Infection after injections or surgery is rare; watch for spreading redness, warmth, and fever and seek care if these appear. Nerve irritation sometimes causes tingling; most cases settle with rest and time.
Plain-Language Meaning Of The Medical Term
Let’s decode the wording. “Full thickness” means the split crosses the tendon wall from top to bottom. “Supraspinatus” names the top rotator cuff tendon that helps lift the arm. “Tear” says the tissue is disrupted not just swollen but torn. Put together, the phrase answers the search: what is a full thickness tear of the supraspinatus tendon.
That sentence spells out the same idea again in everyday English: what is a full thickness tear of the supraspinatus tendon means the lifting tendon on the top of your shoulder has a gap through its whole depth, often near where it attaches to the arm bone.

Frequently Asked Questions
Can A Full-Thickness Tear Heal Without Surgery?
The tendon does not grow back across the gap on its own. Many people still reach workable comfort and function by training the remaining cuff and shoulder blade muscles. The aim is to move well, keep pain low, and match daily tasks to what the shoulder can handle.
Surgery enters the plan when pain and weakness stay high or tasks demand sturdy overhead strength. Age, tear size, and tissue quality guide that choice.
Is An Ultrasound As Good As An MRI For This Tear?
In skilled hands ultrasound can show a full-thickness gap and dynamic pinching. MRI maps the tear, any retraction, and muscle fatty change, and shows other joint issues at the same time. Many clinics start with ultrasound and reserve MRI for surgical planning or unclear cases.
How Long Before I Can Lift Overhead Again?
Nonoperative paths often return people to shoulder-height tasks in 6–12 weeks, with full overhead moves added in steps after strength rebuilds. After a repair, overhead loading waits until the tendon has knit to bone and early strength has returned, often several months.
Do Steroid Shots Harm The Tendon?
One well-timed shot can calm pain enough to train well. Repeated shots near the tendon can hinder healing. Most teams limit the total number and space them out. The goal is to use a short window of pain relief to build motion and strength, then taper off.
What If I Also Have A Bone Spur?
Bone spurs on the acromion can rub on the cuff. Many people still improve with rehab alone. During surgery some surgeons smooth the spur if it narrows the space. Decisions depend on symptoms and tear pattern, not the spur alone.
Wrapping It Up – What Is A Full Thickness Tear Of The Supraspinatus Tendon
A full-thickness supraspinatus tear is a complete split of the top cuff tendon. Early clarity on size and symptoms points to the right plan. Many paths start with targeted rehab, simple pain measures, and task tweaks. When pain and weakness persist or the tear is large and recent, repair can restore lift. With steady rehab and smart load choices, most people regain reliable use for work, home, and sport.
