In clinical settings, elderly individuals commonly experience comminuted fractures, primarily due to their reduced levels of physical activity, which can lead to the loss of proteins, calcium, minerals, and moisture in the bones. This reduces bone strength and density, and if they have osteoporosis, bones can easily break into pieces when subjected to external force. Therefore, it is crucial to apply proper treatment methods promptly after a comminuted fracture occurs. This can involve manual reduction, external fixation, or surgical treatment such as open reduction and internal fixation. Postoperatively, treatments like electrotherapy and physical therapy, along with oral calcium supplements and bone-healing medications, can facilitate recovery. Nutritionally, it is beneficial to consume foods rich in proteins and calcium to aid in the healing of fractures.

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.

How long does it take to walk normally after a comminuted patellar fracture?

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.

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.

Is a comminuted patellar fracture serious?

Patellar comminuted fractures are usually quite severe because once the patella is shattered, it can no longer guarantee a smooth cartilage surface. Moreover, the more severe the fragmentation, the harder it is to restore smoothness. If the smooth surface is not well restored, certain conditions can arise. The first is post-traumatic arthritis, the second is patellar chondromalacia, and the third is patellofemoral arthritis. Therefore, patellar comminuted fractures usually require open reduction and internal fixation surgery. In this surgery, it is crucial to align the cartilage surface of the patella as accurately as possible, making the joint surface as smooth as possible, and then fasten it securely with wire loops or tension bands. If the patellar fragmentation is particularly severe, and it's impossible to restore the integrity of the cartilage surface, it may be considered to remove the patella. If feasible, a prosthetic patella can be installed. If not, the ligaments and joint should be repaired, and then functional exercises should begin three to four weeks post-surgery, although this method of surgery typically results in weakness in extending the knee on the affected side.
