After a patellar fracture occurs, through immobilization or surgical treatment, it's possible to actively contract the quadriceps early on to strengthen muscle exercise and avoid muscle atrophy. Ankle pump exercises can also be performed, which are beneficial for the contraction of the calf muscles in the lower limbs, can help prevent thrombosis, and aid in the recovery of function. After the removal of external fixation or once the wound has healed, one can actively flex the knee joint. For example, by sitting at the edge of the bed with the knee naturally hanging, the knee joint can be flexed to 90 degrees. If there is difficulty in bending, one can push the healthy limb backward against the injured limb to help bend the knee joint. For exercises exceeding 90 degrees, one can lie flat on the bed, then flex the hip joint while holding the thigh of the injured limb with both hands, and allow the knee joint to naturally bend through gravity. This exercise can help restore the flexion and extension functions of the knee joint.

Post-fracture sequelae

After a fracture, the potential sequelae depend on the location of the fracture and the chosen treatment method. For example, fractures involving joint surfaces can lead to traumatic arthritis after treatment. Similarly, femur fractures can lead to the formation of lower limb thrombosis after surgery and the fracture itself. Some fractures near joints might also affect the range of joint motion after treatment. Therefore, the type of sequelae after treating a fracture depends on both the location of the fracture and the treatment approach chosen.

Nasal bone fracture, nasal septum fracture, what kind of injury is this?

What type of injury is a nasal bone fracture and a nasal septum fracture? According to the forensic appraisal regulations concerning the nasal area, there are three situations that can be identified as minor injuries and two situations that can be identified as slight injuries. The three situations for minor injuries are: first, comminuted fracture of the nasal bone; second, linear fracture of the nasal bone where the displacement is very obvious; third, nasal trauma that significantly changes the appearance and function of the nose, which can be identified as a minor injury. The two situations for slight injuries are: first, a simple, nondisplaced nasal bone fracture; second, nasal bleeding after trauma. Therefore, if a nasal bone fracture is combined with a nasal septum fracture, it should be a comminuted fracture and can be identified as a minor injury. If it is solely a nasal septum fracture, it depends on whether it is a comminuted fracture or whether the displacement is obvious. Additionally, the impact of the nasal septum fracture on nasal function must also be considered. Thus, nasal bone fractures and nasal septum fractures require specific analysis based on the details of the injury to determine the type of harm. A slight injury can definitely be determined, but whether it qualifies as a minor injury depends on the specific circumstances.

What does a fracture feel like?

The feeling of a fracture, first and foremost, the most important clinical manifestation is pain. Of course, the intensity of the pain is related to the type of fracture. Generally, incomplete fractures or greenstick fractures are not as painful, but if the fracture is displaced, comminuted, or other types, the pain is more pronounced. The second manifestation is swelling; the area of the fracture will show obvious swelling and become quite enlarged. The third is tenderness, which means that touching or pressing on the area will result in noticeable pain. Fourth, there is a significant restriction of movement in the joints adjacent to the fracture site.

Can I take calcium tablets for a fracture?

After a fracture, there are generally several stages a person will go through. These can typically be divided into the following stages: hematoma organization stage, fibrous connection stage, initial callus stage, mature callus stage, and then the remodeling stage. During these periods, the area of the bone is undergoing a metabolic process involving both osteoclasts and osteoblasts. During this metabolic process, calcium is required, and a deficiency in calcium can affect the healing of the fracture. Therefore, it is advised that patients with fractures should take calcium supplements. Along with calcium, it is also recommended to supplement with vitamin D, which can enhance bone absorption and calcium absorption, aiding in the healing of fractures. Thus, the conclusion is that fracture patients can indeed take calcium tablets.

Does a fracture hurt?

Fractures refer to the disruption of the continuity and integrity of the bone, which can lead to symptoms such as localized pain, swelling, deformity, and even limited mobility. Therefore, pain is a primary symptom of fractures. Due to the displacement of fracture ends and the irritation of nerves around the periosteum, severe pain can occur. After a fracture, it is important to immobilize the affected area to avoid exacerbating the symptoms during transportation or movement, and immobilization can also help reduce localized pain.
