Understanding Pain in Limb-Lengthening Methods

    Pain is a complex and subjective experience that varies greatly from person to person. In the context of limb-lengthening methods, where individuals undergo surgical procedures to increase their height or correct deformities, understanding and managing pain is crucial. 

Factors Influencing Pain Perception

    The experience of pain during limb-lengthening procedures is influenced by various factors. Psychological factors such as anxiety, fear and previous pain experiences can amplify the sensation of pain. Additionally, the individual's pain tolerance, age and overall health can affect how they perceive and cope with pain. The type of surgical technique used, the extent of the procedure and the rate of lengthening also play a significant role in determining the level of pain experienced by the patient.

Psychological Factors

    Anxiety and fear can heighten the perception of pain during limb-lengthening procedures. Patients undergoing these surgeries may experience stress related to the surgical outcome, recovery process and potential complications, all of which can contribute to increased pain sensitivity. Addressing the psychological well-being of patients through counseling and psychological support can help alleviate some of the emotional factors that exacerbate pain.

Surgical Technique and Lengthening Rate

    The method and speed at which the limb is lengthened can impact the level of pain experienced by the patient. Regardless of the methods, there is pain for both the LON (Combined) and the Precice methods after the surgery and during the lengthening process. However, the pain is a little bit less with the Precice 2 method, compared to the LON (Combined) method. There are several reasons it is this way; first of all, there is an external fixator for the LON (Combined) method. This fixator is a little bit heavy and there are 4 pin nails (Schanz screw) that are inserted in the legs. These pin sites create sensitivity on the skin during the lengthening process. Because the pin sites create minimal cuts, the pain that is felt with LON (Combined) method is more than Precice 2 method. 

    There is no external fixator for the Precice 2 method, there are only intramedullary nails but there is still some pain. We should emphasize that pain is subjective and changes from one person to another based on their pain threshold. The pain that is felt right after the surgery is relieved with the strongest painkillers. The first few days after the surgery are usually when the pain is felt the most. It is possible to minimize the patient's pain with epidural catheter or pain pump applications when this pain is at its highest after surgery.

    For both methods, because the muscles, tendons, nerves and overall soft tissue lengthens 1 mm every day, the body aches accordingly. This pain decreases with the painkillers that are given by the doctor and the personalized physical therapy exercises. If the pain is intolerable during the lengthening process, the strongest painkillers are given to the patient under the doctor’s control. The pain during the lengthening process is especially felt at night, therefore, some patients have sleep problems as a side effect. If the patient’s sleep problem is severe, the doctor may give sleeping pills to the patient. Moreover, because some of the screw-turning times happen to be at night, we advise our patients to move their legs, massage them and do some exercises, so that the blood flow increases, some muscle groups are relieved and the pain is a little bit lessened.

    The pain increases for some of our patients after reaching 4 cm lengthening due to tension in some strong muscle groups and nerves. In that case, either physiotherapy sessions of the patient may be increased or some adjustments can be made to the dosage of painkillers that the patient takes with the doctor’s approval. This is valid for both the LON (Combined) and the Precice 2 methods. As we have mentioned before, the pain that the patient experiences changes from patient to patient because everyone’s pain threshold is different. Based on our patients’ feedbacks, the pain is felt more with the LON (Combined) method.

Pain Tolerance and Individual Differences

    Each individual has a unique pain tolerance level, influenced by genetic, physiological and psychological factors. Some patients may have a higher threshold for pain and require less medication, while others may be more sensitive to pain and necessitate more intensive pain management strategies. Understanding these individual differences is crucial in tailoring pain management approaches to meet the specific needs of each patient.

Current Methods of Pain Management

    Pain management in limb-lengthening procedures aims to alleviate discomfort, enhance recovery, and improve overall patient satisfaction. A multimodal approach to pain control is typically employed, combining pharmacological interventions, physical therapy and psychological support.

Pharmacological Interventions

    Medications such as nonsteroidal anti-inflammatory drugs (NSAIDs), opioids and local anesthetics are commonly used to manage pain post-surgery. NSAIDs help reduce inflammation and discomfort, while opioids provide relief from moderate to severe pain. Local anesthetics, administered through nerve blocks or catheters, target specific pain pathways, enhancing the effectiveness of pain management.

Physical Therapy

    Physical therapy plays a vital role in pain management and rehabilitation following limb-lengthening procedures. Gentle exercises, mobility training, kinesio taping, graston therapy and strengthening techniques help improve joint function, reduce stiffness and contribute to the overall well-being of the patient. According to doctors examination, doctor and physical therapists work closely with patients to create personalized treatment plans that address pain and enhance recovery outcomes.

Psychological Support

    Addressing the emotional and psychological aspects of pain is essential in comprehensive pain management. Counseling, mindfulness techniques and relaxation strategies can help patients cope with pain, reduce stress levels and improve their overall quality of life during the recovery process. Integrating psychological support into pain management protocols promotes holistic care and better patient outcomes.

Pain management involves a variety of approaches, including medication, physical therapy and other practical measures to ease discomfort. Besides these, some practical recommendations can contribute to pain relief and promote a smoother recovery process.  Here are 6 practical recommendations:

Hot and Cold Compress: Use hot and cold compresses to reduce swelling and alleviate pain around the surgical area. Consult with your medical team before applying to ensure safety and effectiveness.

Elevation of Limb: Elevate the affected limb to diminish swelling and promote blood circulation which in turn can decrease the pain.

Meditation and Relaxation Techniques: Practice mindfulness meditation, deep breathing, and relaxation techniques to manage pain and reduce anxiety.

Adequate Sleep: Ensure you are getting enough sleep as it is one of the key factors for healing and pain management.

Nutrition: Maintain a balanced diet rich in essential nutrients that support bone healing and overall recovery.

Hydration: Stay well-hydrated by drinking plenty of water throughout the day which can aid in flushing out toxins and promoting healing.

    Pain in limb-lengthening procedures is a multidimensional aspect that involves a combination of psychological and surgical factors. By understanding the various influencers of pain perception and implementing tailored pain management approaches, healthcare providers can optimize patient outcomes, promote faster recovery and improve overall satisfaction.
