The scapholunate ligament plays an important part in wrist motion and strength. If this ligament stretches, tears, or is otherwise injured, it can interfere with normal wrist function and cause significant pain and stiffness.
Prompt treatment intervention is critical in cases of scapholunate ligament injuries. The ligament won’t heal on its own and left untreated, the injury can eventually lead to arthritis.
Consulting with Dr. Jason Ko offers the best chances at treating the injury, reclaiming normal wrist function and overcoming pain. If you are experiencing discomfort, swelling or other symptoms affecting your wrist, the doctor recommends scheduling an evaluation as soon as possible. Injuries to this delicate area require a doctor with Dr. Ko’s level of experience.
Understanding Scapholunate Ligament Injuries
Ligaments are thick bands of tissue that connect two bones. The scapholunate ligament is located in the middle of the wrist, connecting the scaphoid and lunate bones. Though it is a strong ligament, it can be stretched beyond its limits or even tear.
Most scapholunate ligament injuries occur when the wrist is subjected to excessive amounts of force, such as during a fall onto an outstretched hand, or forceful bending or twisting of the wrist. In some cases, the scapholunate ligament can stretch out over time due to the effects of age, repeated strains or chronic inflammation.
Common symptoms of a scapholunate ligament injury include pain and swelling of the wrist. The wrist may also lose some of its normal strength or range of motion, or make a popping noise during movement. A scapholunate ligament injury may cause the wrist to feel warm or even tender to the touch.
To diagnose a scapholunate ligament injury, Dr. Ko performs a comprehensive evaluation of the wrist, checking its strength and movement. He will also take X-rays to get a better look at the bones; a visible gap can be seen between the scaphoid and lunate bones when the ligament holding them together is injured. Sometimes Dr. Ko orders MRIs to determine the extent of the injury.
Reconstructing the Scapholunate Ligament
Some scapholunate ligament injuries are treated with splints/casts to stabilize the wrist. Cortisone shots or anti-inflammatory medications are also commonly used to alleviate pain. However, medications do not address the root cause of the pain and limited function.
If you have sustained a moderate or severe injury, you will probably require surgery to repair or reconstruct the ligament. During surgery, Dr. Ko will reconnect the ligament to the wrist bones, or use a tendon graft to reconstruct the stretched or torn ligament. He can perform traditional “open surgery” or use the minimally invasive arthroscopic approach, depending on the nature of your injury.
Following surgery, you will likely need to work with a physical therapist to rehabilitate and strengthen your wrist. It can take several months up to a year to reclaim full or near-to-full wrist function and range of motion.
