Winged scapula caused by rhomboid paralysis: a case report.

Scapular winging secondary to dorsal scapular nerve (DSN) damage is an underestimated condition. It is often caused by entrapment of the nerve due to a hypertrophic middle scalene muscle, or by stretching of the DSN during traumatic movements. The condition has also been attributed to myofascial pain syndrome of the rhomboids with entrapment of the DSN. The non-specific symptomatology reported by patients is often incorrectly diagnosed, and this can result in a high level of disability of the upper limb. A clinical case of misdiagnosed dorsal scapula entrapment is presented. Satisfactory shoulder function recovery, pain relief and reduction of disability were obtained after correct diagnosis of the condition and a comprehensive rehabilitation approach.
