If the surgery is performed without any issues, you can start normal knee flexion and extension exercises about three days after the surgery. Then, about a week later, you can begin walking with the aid of crutches. At six weeks post-surgery, you should return to the hospital for a follow-up. If there is continuous callus formation along the fracture line, you can walk normally. However, you need to be cautious at this time, as the fracture healing is not very solid, and it is best to avoid vigorous activities. Activities like running and jumping should be postponed until about three months later. Therefore, for patellar comminuted fractures, you can generally walk normally between six to twelve weeks after the surgery.

Is a pelvic comminuted fracture serious?

For comminuted pelvic fractures, the condition is very serious, demonstrating that the external force involved was quite significant. It causes a disruption in the continuity and integrity of the bone. The patient will exhibit localized pain and swelling, and restricted movement in the affected area. Pressing on the area will produce a distinct bone crepitus or feel, and there might be extensive subcutaneous bruising. For comminuted pelvic fractures, the primary treatment is usually surgical. It is essential to conduct thorough preoperative examinations to exclude any surgical contraindications, and then proceed with the open reduction and internal fixation surgery under general anesthesia.

Sequelae of comminuted fracture of the humerus

Regarding the sequelae of comminuted fractures of the humerus, in clinical practice, if treatment for humerus comminuted fractures is proactive and patients diligently engage in functional exercises without any nerve damage, most patients will not experience any sequelae. However, if treatment is improper, a series of sequelae can often occur, mainly reflected in the following aspects: First, if there is accompanying nerve damage that is very severe, it can cause patients to experience sensory disturbances or motor function impairments. Second, poor repositioning of comminuted fractures can lead to nonunion or malunion of the fracture, affecting normal functions of the patient. Third, long-term immobilization in the later stages can cause joint stiffness. When patients eventually start exercising, fear of pain may lead to insufficient exercise, resulting in very poor joint mobility, thereby affecting normal functions.

Will a comminuted patella fracture cause limping?

Patellar comminuted fractures, as long as treated promptly and correctly, and if the surgery poses no issues, generally heal in about six months, thereby not causing any significant impact. Thus, there's no need to worry about limping. Limping usually means that when walking, one leg appears longer than the other. Under what circumstances can limping occur? If the difference in leg length is within one centimeter, it's imperceptible and won't have any effect. If the difference exceeds two centimeters, then there is a noticeable tilt in the lower limbs, and only then can limping be observed during walking; however, even if limping occurs, it is not severe. It just means that while walking, there is a tilt towards the shorter side. After treatment, patellar comminuted fractures have a complete chance of healing and once healed properly, it's almost like before the injury. Even in severe cases where the fracture is critically fragmented and requires removal, even without patellar replacement, by reinforcing the patellar tendon, it typically does not result in limping. It only impacts the strength in knee extension, possibly creating a mild impediment compared to the other side, and might make walking appear slightly abnormal, but it definitely does not lead to limping. Hence, patellar comminuted fractures do not result in limping.

Can a pelvic comminuted fracture cause paralysis?

A pelvic fracture generally includes avulsion fractures, in which the pelvis remains stable, while other types of fractures tend to be comminuted fractures. Whether paralysis occurs following such a fracture depends on whether there is nerve damage. If there is no significant nerve damage, paralysis is generally unlikely; however, if the fracture is accompanied by nerve damage, such as damage to the sacral nerves causing numbness and limited mobility, it may significantly impact function, especially of the lower limbs. Therefore, it is advised to seek treatment in the orthopedic department of a reputable hospital if a pelvic fracture occurs.

How long will it take for a comminuted ankle fracture to heal?

Hello! You're asking how long it takes for a comminuted ankle fracture to heal. Generally, the healing time for a comminuted fracture in the ankle is about three months. Depending on your specific condition, you may need to have an X-ray to confirm if your ankle fracture has achieved bony union. If bony union has been achieved, you can then appropriately begin weight-bearing activities to promote blood circulation in the lower limbs and restore joint mobility. However, if the X-ray shows that bony union has not been achieved, it is absolutely crucial not to bear weight. Premature weight-bearing can cause the fracture ends to break again and shift, potentially necessitating a second surgery. So, generally speaking, the healing time for non-comminuted ankle fractures is also about three months, but it is essential to check the final X-ray to see if the fracture has healed.
