Prevent Disease.com - Osteolysis of Clavicle - Weighlifters at Risk for Collarbone Damage
Lifting weights is one of the best ways to stay in shape and                  feel good. However, because weightlifting can put tremendous strains                  on your body, injuries can be lurking right around the corner.                  
One type of injury found in weightlifters is osteolysis of the                  distal clavicle (ODC), a condition in which the collarbone slowly                  breaks down and dissolves, causing pain, instability, and reduced                  mobility and strength. Previous research has shown that ODC occurs                  in over one-quarter of competitive weightlifters. Current research                  is showing that the condition is indeed very common in both serious                  amateur and competitive weightlifters.
In a recent study in the Journal of Sports Chiropractic and                  Rehabilitation, researchers sought to determine the odds of                  recreational weightlifters developing ODC. Twenty-nine individuals                  who had lifted weights at least two-to-three times per week for                  over six months completed a questionnaire regarding shoulder pain                  and training/ health history. X-rays of both shoulders were obtained                  and evaluated for ODC in all subjects.
ODC was diagnosed in half of all shoulders - much greater than                  would be expected in nonlifters, and nearly double the prevalence                  found in competitive weightlifters. The ODC-afflicted shoulder                  joints also exhibited gradual widening and deformation. 
Patients generally have well-developed shoulder musculature with                  full range of motion but have trouble fully horizontally adducting                  the arm without pain. Night pain is not often a complaint but                  the patient typically will have difficulty sleeping on the afffected                  side if pressure on the shoulder is increased. 
Typically, patients cannot recall a specific incident which precipitated                  their symptoms (called atraumatic osteolysis). They can have pain                  with specific orthopedic exams (i.e. rotator cuff and impingement                  tests) making the original diagnosis very difficult for non-specialists                  and general practitioners. 
Weightlifters often have the most pain while performing bench                  presses, push-ups, dips and the clean and jerk. These athletes                  generally see a regression of symptoms if these exercises are                  avoided or somewhat modified.
The occurrence of this condition does not seem to be affected                  by how often or long a person has trained. If you lift weights,                  adopt a consistent, moderate regimen, and never lift more weight                  than you're capable of lifting safely. If you do take a period                  of time off, gradually work your way back into the sport so that                  your tissues have time to rebuild.
