Remodeling or also known as maturation phase is the fourth and final phase in wound healing and lasts from 21 days up to 2 years. In this final and longest phase, collagen synthesis is ongoing in order to strengthen the tissue. Remodeling occurs as wound continues to contract and fibers are being reorganized.
During which phase of the healing process do phagocytic cells clean up the area?
Inflammation
The second phase of wound healing is called the Inflammatory Phase. It involves phagocytic cells that release reactive oxygen species, lasting for up to seven days in acute wounds and longer in chronic wounds.
Which of the following is the final stage of wound healing?
The last stage of wound healing is the maturation stage, sometimes called the remodeling stage. The goal of this stage is to strengthen the repair.
Which cells lay down extra bone formation over a fracture?
What is the remodeling phase of a scar?
The third phase of healing consists of remodeling, which begins two to three weeks after the onset of the lesion and can last for one year or more. The core aim of the remodeling stage is to achieve the maximum tensile strength through reorganization, degradation, and resynthesis of the extracellular matrix.

Frequently Asked Questions
What cells help our bones remodel and heal fractures?
Bone fractures heal through the action of skeletal progenitor cells: stem cells that are partially specialized, but can still develop into several different types of cells.
What is the remodeling phase of bone healing?
The remodeling stage starts around 6 weeks after the injury. In this stage, regular bone replaces the hard callus. If you saw an X-ray of the healing bone, it would look uneven. But over the next few months, the bone is reshaped so that it goes back to looking the way it did before the injury.
What are the stages of bone Remodelling?
The remodelling cycle occurs within the basic multicellular unit and comprises five co-ordinated steps; activation, resorption, reversal, formation and termination. These steps occur simultaneously but asynchronously at multiple different locations within the skeleton.
What are the 4 steps of bone remodeling in order?
- Hematoma formation.
- Granulation tissue formation.
- Bony callus formation.
- Bone remodeling.
What happens after bone remodeling?
The remodeling stage starts around 6 weeks after the injury. In this stage, regular bone replaces the hard callus. If you saw an X-ray of the healing bone, it would look uneven. But over the next few months, the bone is reshaped so that it goes back to looking the way it did before the injury.
What is the correct order of events for bone remodeling?
There are five phases in the bone remodeling process: ACTIVATION, RESORPTION, REVERSAL, FORMATION, and QUIESCENCE. The total process takes about 4 to 8 months, and occurs continually throughout our lives.
What are the 5 stages of bone remodeling?
The remodelling cycle occurs within the basic multicellular unit and comprises five co-ordinated steps; activation, resorption, reversal, formation and termination. These steps occur simultaneously but asynchronously at multiple different locations within the skeleton.
How long does it take for a bone stress reaction to heal?
These include how long you have had your symptoms, the location of the bone injury or fracture, your previous activity levels and other factors that are specific to you. However, as a general guideline, bone can take up to 6 weeks to heal. The majority of people get back to sport or their activities within 10-16 weeks.
FAQ
- How long does it take for bone remodeling to occur?
About 4 to 8 months
About 20% of all bone tissue is replaced annually by the remodeling process. There are five phases in the bone remodeling process: ACTIVATION, RESORPTION, REVERSAL, FORMATION, and QUIESCENCE. The total process takes about 4 to 8 months, and occurs continually throughout our lives.
- Do bones remodel after stress?
- The shape of bone changes as a result of bone remodeling corresponding to physical circumstances such as mechanical stress. The tissue which receives the loaded mechanical stress most efficiently is bone matrix. Recent studies revealed the function of osteocytes as mechanosensors in the early stage of bone remodeling.
- What happens when stress is applied to a bone?
Stress fractures often result from increasing the amount or intensity of an activity too quickly. Bone adapts gradually to increased loads through remodeling, a normal process that speeds up when the load on the bone increases. During remodeling, bone tissue is destroyed (resorption), then rebuilt.
- How do I know if my stress fracture is healing?
- After you can walk without pain—which indicates the bone has healed completely—you can likely return gradually to the activity that caused the stress fracture. The exact length of time it takes the bone to heal may depend on the severity and location of the stress fracture and your overall health.
- What happens in the remodeling stage of bone healing?
The Remodeling Stage
In this stage, regular bone replaces the hard callus. If you saw an X-ray of the healing bone, it would look uneven. But over the next few months, the bone is reshaped so that it goes back to looking the way it did before the injury.
- What is the process of bone remodeling repair?
The remodeling cycle consists of three consecutive phases: resorption, during which osteoclasts digest old bone; reversal, when mononuclear cells appear on the bone surface; and formation, when osteoblasts lay down new bone until the resorbed bone is completely replaced.
- What are the events of bone healing?
There are four stages in the repair of a broken bone: 1) the formation of hematoma at the break, 2) the formation of a fibrocartilaginous callus, 3) the formation of a bony callus, and 4) remodeling and addition of compact bone.
- What is the timeline of bone remodeling?
About 20% of all bone tissue is replaced annually by the remodeling process. There are five phases in the bone remodeling process: ACTIVATION, RESORPTION, REVERSAL, FORMATION, and QUIESCENCE. The total process takes about 4 to 8 months, and occurs continually throughout our lives.
Which of the following phases of healing features a realignment or remodeling of scar tissues?
| What are the 4 stages of bone healing and remodeling? | Following the fracture, secondary healing begins, which consists of four steps:
|
| What are the 5 stages of bone growth? | 30.2A: Stages of Bone Development
|
| What are the steps of bone remodelling? | The remodeling cycle consists of three consecutive phases: resorption, during which osteoclasts digest old bone; reversal, when mononuclear cells appear on the bone surface; and formation, when osteoblasts lay down new bone until the resorbed bone is completely replaced. |
| What changes does a bone go through when healing? | The bone healing process has three overlapping stages: inflammation, bone production and bone remodeling. |
| What to expect when a broken bone is healing? | Over the next 4-21 days, you get a soft callus around the broken bone. This is when a substance called collagen moves in and slowly replaces the blood clot. The callus is stiffer than a clot, but not as strong as bone. That's part of the reason you get a cast -- it holds the healing bone in place. |
| What are the 4 stages of bone healing? | Following the fracture, secondary healing begins, which consists of four steps:
|
| How do you tell if a fracture is healing? | The signs that a broken bone is healing are often typically an improvement in mobility and a decrease in pain. While the progress may not be consistent, each week should be an improvement from the previous. But the signs that your broken bone is not healing properly may be less clear cut. |
| What factors can cause bone atrophy? | A lifelong lack of calcium plays a role in the development of osteoporosis. Low calcium intake contributes to diminished bone density, early bone loss and an increased risk of fractures. Eating disorders. Severely restricting food intake and being underweight weakens bone in both men and women. |
- What factors affect bone remodeling?
Besides systemic hormonal regulation, other growth factors, such as IGFs, TGF-β, FGFs, EGF, WNTs, and BMPs, also play a significant role in regulation of physiological bone remodeling.
- Which of the following factors influence bone remodeling?
- Bone growth factors affect the process of bone remodeling. These factors include insulin-like growth factors I and II, transforming growth factor beta, fibroblast growth factor, platelet-derived growth factor, and bone morphogenetic proteins.
- What is unlikely to affect bone remodeling?
- glucagon. Glucagon's main action is to increase blood glucose levels by triggering the breakdown of glycogen in the liver; it does not affect bone remodeling.
- What happens during bone atrophy?
Also known as bone atrophy, a reduction in bone density due to the excessively fast breakdown of the bone substance and structure is a characteristic of this disease. This makes the bones more susceptible to fractures and can affect the entire skeleton. Osteoporosis is the most common bone disease in advanced age.
- What are the 4 stages of bone healing or remodeling?
- Following the fracture, secondary healing begins, which consists of four steps:
- Hematoma formation.
- Granulation tissue formation.
- Bony callus formation.
- Bone remodeling.
- Following the fracture, secondary healing begins, which consists of four steps:
- What is the development of bone healing?
- The reparative stage starts within about a week of the injury. A soft callus (a type of soft bone) replaces the blood clot that formed in the inflammatory stage. The callus holds the bone together, but isn't strong enough for the body part to be used. Over the next few weeks, the soft callus becomes harder.
- What is the first stage in the healing of a bone fracture?
Stage 1: Immediately following trauma, the first stage of fracture healing is blood clotting (haematoma formation) and inflammation, which begin within the fracture site. Stage 2: Repair phase, the granulation tissue is replaced by soft (cartilaginous) and then hard callus of woven bone at the fracture site.
- What are the steps of bone remodeling in order?
The remodeling cycle consists of three consecutive phases: resorption, during which osteoclasts digest old bone; reversal, when mononuclear cells appear on the bone surface; and formation, when osteoblasts lay down new bone until the resorbed bone is completely replaced.
