Elbow Joint Contracture — When the Arm Won't Fully Straighten
Table of Contents
An elbow that neither extends nor flexes
Elbow contracture is a condition in which the joint's range of motion (ROM) falls short of normal. A normal elbow moves from full extension (0 degrees) to full flexion (about 140–150 degrees), but with contracture this range is markedly reduced. The functional ROM needed for daily life is flexion of 30–130 degrees, and once even this range is lost, basic activities such as eating, washing the face, and combing the hair become difficult.
Causes of joint contracture
Elbow contracture mostly develops after trauma. Fracture, dislocation, and prolonged immobilization after surgery are the most common causes, but it can also follow chronic arthritis or burns.
- Joint capsule contracture: The joint capsule thickens and becomes fibrotic, restricting joint motion.
- Muscle and tendon shortening: Surrounding muscles and tendons shorten, reducing both active and passive ROM.
- Heterotopic ossification: Abnormal bone forms within muscle tissue after trauma, mechanically blocking joint motion.
Korean medicine treatment: synergy of chuna and needle-knife therapy
Chuna manipulation (joint mobilization) gradually expands the range of the joint capsule, while needle-knife therapy releases adhered and fibrotic soft tissue. Combining the two treatments addresses both causes of joint contracture — capsular restriction and soft-tissue adhesion — at the same time.
- Chuna joint mobilization: Graded joint movements (Grade I–IV mobilization) to stretch the joint capsule
- Needle-knife therapy: Precisely releases adhesions and fibrotic tissue to restore tissue gliding
- Acupuncture and moxibustion: Relieves muscle tension and promotes blood flow, maximizing treatment effect
- Exercise therapy: Active exercises to maintain and expand the ROM gained from treatment
Consistent treatment is essential
Joint contracture cannot be resolved with one or two sessions. Treatment 2–3 times per week must continue for several weeks, gradually expanding ROM. Faithfully performing home exercises between sessions determines the final outcome.
