ABSTRACT
Pectoralis major (PM) rupture is a rare injury, commonly misdiagnosed, that affects mostly young male athletes aged 20-40 years. This type of injury is typically associated with weight lifting, especially bench pressing. In an occupational medicine setting, it is extremely rare and not much reported in the literature. We present the case of a 30-year-old trauma technician male who presented with right shoulder and chest pain following a popping sensation while pushing in full momentum a patient on a gurney accidentally set on break mode. PM rupture was suspected clinically. Magnetic resonance imaging confirmed the diagnosis and revealed a complete rupture of the sternal head of PM. Surgical reconstruction was performed to restore the anatomy and functionality of the shoulder girdle.
ABSTRACT
One-hundred consecutive patients were prospectively evaluated on admission to our Brain Injury Unit for signs and symptoms of reflex sympathetic dystrophy (RSD) in the upper extremity. Patients averaged 4 months postinjury and had an average age of 29 years. Thirteen patients had clinical signs and symptoms of RSD and were then evaluated with standard radiographs and 3-phase radionuclide scintigraphy. Twelve of 13 patients had 3-phase bone scans (TPBS) consistent with RSD (12% overall incidence). RSD was present exclusively in the spastic upper extremity. There were 9 patients with hemiparesis and 3 with quadraparesis. There was a significantly higher (P < 0.01) incidence of associated upper extremity injury in the group with RSD (75%). All patients had a mean Rancho Cognitive Level of V and initial Glasgow Coma Scores less than 8. Patients who developed RSD had lower Glasgow Coma Scores than the non-RSD patients. Brain-injured patients often display agitation, hyperalgesia, disuse or neglect of the RSD-involved extremity. In addition, these patients are often cognitively unable to vocalize complaints of pain. Undiagnosed RSD in these patients can result in a significant delay in rehabilitation and possible loss of the use of an otherwise functional upper extremity.
