Latissimus Dorsi Flap Recovery Week by Week: Timeline, Shoulder Exercises and Tips
How long is recovery after a latissimus dorsi flap? Most women stay 1 to 3 days in hospital and keep their drains for 7 to 14 days. Light work and most daily tasks return around weeks 4 to 6. Full activity, including sport, usually takes 3 to 6 months. This guide walks you through latissimus dorsi flap recovery week by week.
A latissimus dorsi flap (LD flap or lat flap) uses skin, fat and muscle from your upper back to rebuild the breast. The tissue keeps its own blood vessels, so the flap is very reliable. What makes recovery special is that your body heals in two places at once: the chest and the back. Many women are surprised that the back feels worse than the chest in the first days. Knowing this in advance helps you prepare.

Week 1 after latissimus dorsi flap surgery
What you may notice. You spend 1 to 3 days in hospital. This is shorter than after a DIEP flap, because no microsurgery is needed. You have small drains in the chest and in the back. Nurses check the colour and warmth of the new breast several times a day. Your back feels tight and sore, especially when you lie down or turn over. Pain is usually moderate in the first week and then eases.
What is normal. Pain medicine starts stronger and is changed to over-the-counter tablets as you heal. A pulling feeling under the arm is common, because the flap passes through a tunnel there. You may feel more comfortable half-sitting, with pillows behind your back and under your arm. Short walks around the ward are encouraged from the first day.
What to discuss with your team. Ask how to empty and record your drains at home, and when they are likely to come out. Ask for a clear pain plan and for advice on showering with drains. Make sure you know who to call if you are worried once you are home.
Week 2 after latissimus dorsi flap surgery
What you may notice. You are at home, and rest is the main task. Keep activity very light. Drains usually stay 7 to 14 days, so some women still have one or both drains this week. You feel tired, and the back may still be the sore spot. Swelling and bruising around the new breast and on the back are common.
What is normal. The amount of drain fluid slowly goes down before the drains are removed. The skin on your back and under your arm may feel numb or oddly sensitive. This is because small skin nerves were cut during surgery. It often improves over months, but a numb patch on the back can stay. Feeling low or tearful in the second week is also common and usually passes.
What to discuss with your team. Ask when your drains will be removed and how the wounds will be checked. Ask when physiotherapy starts; it often begins between week 2 and week 4. If you notice a soft, sloshing swelling on your back, mention it. It may be a seroma, which is explained below.
Weeks 3–4 after latissimus dorsi flap surgery
What you may notice. You can slowly do more around the house. The drains are usually out. Your surgeon will still ask you not to reach above your head and not to lift for about 3 to 4 weeks. This protects the new tissue and the tunnel under the arm. Physiotherapy starts with gentle exercises for the shoulder and arm.
What is normal. A stiff shoulder and a tight feeling across the back scar are normal at this stage. The new breast may feel firm and sit a little high. It settles over the coming months. You may be tired by the afternoon; that is your body healing in two places.
What to discuss with your team. Ask for a written exercise programme and how often to do it. Ask when you may drive again; this depends on how freely you can move your arm and on your pain medicine. Ask when you may sleep on your side.
Weeks 5–6 after latissimus dorsi flap surgery
What you may notice. Most women return to light or desk work and to nearly all daily tasks around weeks 4 to 6. Heavy lifting is still not allowed. Your shoulder moves more freely each week if you keep up your exercises. The scars are still red or pink; that is expected.
What is normal. Some tightness under the arm and across the back can remain for weeks. The back skin around the scar may still be numb. A small difference in shape between the two breasts is normal at this stage; final shape takes months.
What to discuss with your team. Ask whether you may start scar care, such as gentle massage or moisturiser, once the wounds are fully closed. Ask what kind of bra is best for now. If you have a tissue expander, ask when the first filling is planned.
Weeks 7–12 after latissimus dorsi flap surgery
What you may notice. This is the time to build up step by step. More demanding physical activity returns by weeks 8 to 12. Listen to your body and increase slowly. Most women can now reach overhead comfortably and lift everyday loads.
What is normal. The shoulder is close to its full range of movement for most women. Some notice that pulling or lifting with that arm feels a little weaker than before. Other muscles take over most of the work, and strength keeps improving. The numb patch on the back slowly shrinks.
What to discuss with your team. Ask when you may return to your usual sport, and whether any exercise is best avoided for a while longer. Ask what the next steps are: expander fillings, an exchange for an implant, nipple reconstruction, or fat injections (lipofilling) to smooth the shape.
Months 3–6 and beyond
What you may notice. By 3 to 6 months, most women are back to all activities, including sport. The new breast becomes softer and settles into its final position. Healing continues quietly in the background. Scars keep fading over 12 to 18 months.
What is normal. The moved muscle can sometimes twitch or tighten when you use your arm, for example when you pull a door. This is called animation and is usually mild. Mild weakness when pulling or lifting can remain for women who use this muscle a lot, such as rowers, climbers or swimmers. A numb area on the back or under the arm may be permanent, but it rarely bothers daily life.
What to discuss with your team. Discuss any twitching that bothers you; there are ways to reduce it. Discuss whether you want a nipple reconstruction, a small correction of the other breast for symmetry, or lipofilling. These are usually planned once the breast has fully settled.
Seroma after a latissimus dorsi flap: the most common issue
A seroma is a pocket of clear fluid under the skin. After an LD flap, it forms most often on the back, in the space where the muscle was taken. It is the most common issue after this operation. You may notice a soft swelling that feels like a water balloon, sometimes only after the drains have come out.
A seroma is not dangerous in itself, but it can feel uncomfortable and heavy. Your team can remove the fluid in the clinic with a thin needle. This is quick and usually not painful, because the skin there is numb. Sometimes this needs to be repeated a few times before the space closes. Most seromas settle within a few weeks. Rest, avoiding heavy arm use and sometimes a firm support garment help the space to close.
Do contact your team if the swelling grows quickly, becomes red or warm, or if you develop a fever. These can be signs of infection and need a check.
Shoulder and arm exercises after an LD flap
Moving from a limited to a normal arm movement is one of the big milestones of LD flap recovery. A physiotherapist guides you safely, usually from week 2 to 4. In the first weeks, the aim is gentle range of movement, not strength: slow shoulder rolls, letting the arm hang and swing, and gradually walking the fingers up a wall. Do only what your own team has instructed, and stop if pain increases sharply.
Avoid reaching above your head and lifting for about 3 to 4 weeks. After that, you slowly widen the movements. Strength returns gradually over the following months. Most women adapt well, because other shoulder muscles take over the work of the moved muscle. A small number of women notice a lasting difference during heavy pulling or lifting.
Swimming, rowing, climbing and other sports that pull hard on the back come last. They are usually possible again between 3 and 6 months, once your team has cleared you. Build up slowly and keep doing your exercises; they make the biggest difference to how your shoulder feels a year from now.
Back scar care
The back scar is a horizontal or slightly diagonal line on the upper back. Your surgeon plans it so that a bra strap can hide it. In the first weeks, keep the wound clean and dry and follow the wound instructions from your team. Once the skin is fully closed, gentle massage with a plain moisturiser can make the scar softer and flatter. Some teams also advise silicone sheets or gel.
Protect the scar from the sun in the first year, as fresh scars darken easily. Numbness around the scar is normal and slowly improves. Scars are usually red or pink for months and fade over 12 to 18 months. If a scar becomes thick, raised or itchy, tell your team; there are treatments that help.
If an implant or expander was placed with the flap
The back tissue alone is often not enough for the full breast size. Many women therefore have a small implant under the flap, or first a tissue expander. With an implant, the usual implant points apply: the breast may feel firmer at first, and over the years the capsule around the implant can tighten. With an expander, the fillings start once the wounds have healed, usually a few weeks after surgery. Later, a second, smaller operation exchanges the expander for the final implant.
An implant or expander does not change the week-by-week timeline much. The rules on lifting and reaching are the same, and the drains are the same. Your team will tell you if you should wear a support bra for longer.
When to contact your care team
Fever, or redness, warmth and increasing pain around the breast or back wound.
The new breast changes colour, becomes cold, dark or very swollen.
A swelling on the back that grows fast, or a wound that leaks fluid or opens.
Drain fluid that suddenly becomes bright red, or a drain that stops working.
A painful, swollen calf, chest pain or shortness of breath; call your local emergency number.
You feel very low, anxious or unable to cope at home.

Frequently asked questions
How long does latissimus dorsi flap recovery take?
Most women stay 1 to 3 days in hospital and have drains for 7 to 14 days. Light work returns around weeks 4 to 6. Full activity, including sport, takes 3 to 6 months. The scars keep fading for 12 to 18 months.
What is the LD flap recovery time before I can go back to work?
Light or desk work is usually possible around weeks 4 to 6. Physical work that involves lifting or reaching often needs 8 to 12 weeks. Discuss your job with your surgeon, because every situation is different.
Why does my back hurt more than my chest after a lat flap?
The back is where the muscle, skin and fat were taken. That area is often the most sensitive in the first weeks, especially when lying down or turning. Good pillow support and gentle movement help. The back pain eases over the first weeks.
What is a seroma after a latissimus dorsi flap?
A seroma is a pocket of clear fluid under the skin of the back, where the muscle was removed. It is the most common issue after an LD flap. Your team can drain it in the clinic with a thin needle, sometimes more than once. Most seromas settle within a few weeks.
When can I start shoulder exercises after a latissimus dorsi flap?
Gentle shoulder and arm exercises usually start between week 2 and week 4, guided by a physiotherapist. Avoid reaching overhead and lifting for about 3 to 4 weeks. After that, you build up movement and strength step by step.
Will I lose strength in my back or arm after an LD flap?
Most women adapt well, because other shoulder muscles take over. A small number notice a lasting difference during heavy pulling or lifting, for example in rowing, climbing or competitive swimming. Physiotherapy helps you get the most out of your recovery.
When can I swim or do sport again after an LD flap?
Walking is encouraged from the first days. More demanding activity returns around weeks 8 to 12. Swimming and sports that pull hard on the back usually wait until 3 to 6 months, once your wounds are fully healed and your team has cleared you.
Does an implant or expander change LD flap recovery?
Not much. The week-by-week timeline, the drains and the rules on lifting are the same. With a tissue expander, fillings start once the wounds have healed, and a second smaller operation later exchanges the expander for the final implant.
Questions to ask your surgeon
How long do you expect my drains to stay, and who removes them?
When does my physiotherapy start, and which movements should I avoid at first?
What should I do if I notice a swelling on my back after the drains are out?
Will I have an implant or an expander with the flap, and what does that mean for my timeline?
When can I drive, return to work and go back to my sport?
