Scapula winging is an uncommon condition but one which may be underdiagnosed. Four patients with scapula winging referred to a sports injury clinic are presented. None of the patients was aware of any trauma and a traction injury to the long thoracic nerve is proposed as the aetiology of this condition. These case reports emphasize the importance of excluding winging of the scapula in patients who present to sports injury clinics with shoulder pain.
