A partial biceps rupture may not appear dramatic at first glance, but without proper management, it can lead to long-term functional limitations in the upper limb. This injury refers to an incomplete tear of muscle or tendon fibers, most commonly involving the long head of the biceps tendon, which plays a key role in elbow flexion and forearm supination.
Injury typically occurs due to sudden forceful movements, overload, or incorrect exercise technique. The main symptom is a sharp, sudden pain in the front of the shoulder or elbow, sometimes accompanied by bruising or mild swelling. Unlike a full rupture, there is usually no visible deformity, and the tendon remains partially intact.
Acute Phase Care (First Days)
In the first hours to days after injury, the focus is on reducing pain and swelling:
- Application of ice
- Resting the arm
- Elastic bandage or brace
- Pain relief medication may be used short-term in case of severe discomfort
Early Rehabilitation (Days 2–7)
Once the acute symptoms settle (typically within 2–3 days), rehabilitation begins. The initial goals are:
- Maintaining range of motion in the shoulder and elbow
- Preventing muscle atrophy
- Gently activating the biceps in pain-free ranges
By day 7, the patient usually begins:
- Assisted mobilization of the shoulder and elbow with a therapist
- Isometric exercises (muscle activation without movement)
- Shoulder stabilization and soft tissue release techniques
- Modalities like TENS to reduce pain and promote healing
Patient Progress at 14 Days
After two weeks of consistent physical therapy, our patient showed significant improvement, as there were no complications during recovery. The observed outcomes included:
- Pain intensity dropped from an initial 6–8/10 to 1–2/10 with regular movements
- Range of motion in the shoulder and elbow recovered to 80–90%, without pain
- Biceps strength remained slightly reduced (by about 20–30% compared to the healthy side), but the patient could perform daily activities without issues
- Swelling and bruising resolved, with no remaining tenderness
- The patient became increasingly aware of movement limits and learned how to safely use the affected arm
Day 14 marked a key turning point — shifting from protective measures to an active rehabilitation phase. We began:
- Functional shoulder stability exercises
- Coordination training between scapular and arm muscles
- Light biceps strengthening with low resistance
- Patient education on avoiding risky movements and how to safely return to routine and athletic activities
Even with a partial tendon injury, targeted rehab can bring significant improvement within just two weeks. In this case, pain decreased, movement improved, and the patient returned to normal daily function.
The key to success was:
- Early initiation of therapy
- A personalized rehabilitation plan
- Patient motivation and cooperation throughout the process
