What is a Closed Lock?
The holiday season is a time for festive meals and special treats, but what if a condition like a closed lock, also known as lock-jaw, hinders your ability to enjoy these culinary delights? Let's delve into what a closed lock entails and how it can impact your temporomandibular joint (TMJ).
A closed lock is clinically diagnosed as a Disc Displacement Without Reduction (DDWOR). The TMJ consists of a fibrocartilaginous disc situated between the mandible (lower jaw bone) and the temporal bone (skull bone). In a healthy joint, the mandibular condyle smoothly interacts with the disc, facilitating jaw movement.
The disc is supported by connective tissue that helps maintain its position and prevents excessive forward movement of the disc. However, when this connective tissue becomes overstretched, the disc may shift forward within the joint space, resulting in a clicking sound as the condyle moves. This condition is clinically diagnosed as a Disc Displacement With Reduction, and in most cases is not painful nor does it impede on normal functioning of the jaw.
A very small percentage of people who are experiencing this disc clicking can progress to a DDWOR, where the disc obstructs the condyle from moving enough to allow the jaw to open fully. This condition may cause pain, stiffness, and a noticeable deflection of the jaw during movement. Physical therapy plays a crucial role in managing acute DDWOR by utilizing muscle release techniques, trigger point dry needling, and joint mobilizations to alleviate symptoms and restore functional movement.
The TMJ is remarkably adaptable and tissue remodeling can occur to create a "pseudo-disc" that facilitates smooth joint motion. If you suspect you are experiencing a closed lock or DDWOR, seeking professional help is essential. Trained clinicians can assist in restoring jaw mobility, alleviating discomfort, and ensuring you can savor those holiday meals without hindrance.
