Scapholunate Ligament Tear

The scapholunate ligament connects two small carpal bones, scaphoid and lunate, in the wrist joint. Scapholunate Ligament Tear is a common injury that occurs when the scaphoid and lunate do not move together as they normally do. The scaphoid bends forward whereas the lunate bends backwards, forming a gap between the two bones.

A Scapholunate Ligament Tear can range from a mild sprain to severe tear in the ligaments. It can also be accompanied by a scaphoid fracture or lunate dislocation. Based on severity, Scapholunate Ligament Tear can be divided into four categories:

  • Pre-dynamic injury: Partial tear of the ligament
  • Dynamic Injury: Ligament gets stretched beyond capacity and the surrounding ligaments may also be injured
  • Static Injury: Complete tear of the ligament with prominent gap between lunate and scaphoid
  • Scapholunate Advanced Collapse (SLAC) Injury: Not seeking timely treatment for a Scapholunate Ligament Tear can lead to this complication

Causes Of Scapholunate Ligament Tear

  • Accident or trauma due to a fall

Diagnosis Of Scapholunate Ligament Tear

  • The hand surgeon may conduct a physical examination of the affected wrist
  • He may evaluate the symptoms being experienced by the patient
  • X-ray may be done to get a clear picture of the bone structure
  • Stress tests may be conducted to check the grip strength

Treatment For Scapholunate Ligament Tear

The treatment options for a Scapholunate Ligament Tear may depend on the severity of the condition.

Non-surgical treatment

  • A splint or cast may be helpful in treating partial injury that has not caused any instability of the scapholunate joint
  • Taking a prescribed course of non-steroidal anti-inflammatory medications may provide relief from pain and swelling
  • Specific hand and wrist exercises may also help to improve the condition

Surgical treatment

Surgical treatment options may include arthroscopic debridement and thermal shrinkage of the ligament. Stitches may be used to repair the ruptured ligament and bones may be held together by inserting temporary internal wires. A splint or cast may be recommended for a few weeks post-surgery
