“…Češće se javlja kod muškaraca, a učestalost u suvremenim populacijama iznosi između 1% i 15% (Resnick 2002;Boehm 2005). Kao uzrok nastanka os acromiale navode se mehanički stres i trauma te genetički čimbenici (Case et al 2006). Istraživanja su pokazala da je rizik od nastanka os acromiale veći u osoba koje su tijekom života obavljale naporne fizičke aktivnosti čiji su pokreti uključivali ponavljajuće podizanje ruku.…”

“…It is more frequent in men, appearing in modern populations with frequencies between 1% and 15% (Resnick 2002;Boehm 2005). Os acromiale is caused by mechanical stress and trauma, as well as genetic factors (Case et al 2006). Research has indicated that the risk of developing os acromiale is greater in individuals who were involved in strenuous physical activities that required repetitive arm rising during their lifetime.…”

Arthroscopic excision of unstable <i>os </i><i>acromiale</i> associated with impingement syndrome: a case report

The acromial apophysis develops from four separate centers of ossification : pre -acromion, meso-acromion, meta-acromion, and basi -acromion (1). Complete union of all centers may occur by the age of 25 years (2). Os acromiale is a failure of union of the acromial apophysis of the scapula, with a reported incidence ranging from 1% to 18.2% (1,3,4). Bilateral involvement is found in 33.3 -62% of cases. It is thought to be an anatomical variant of the scapula and rarely causes shoulder pain.Although os acromiale is usually identified incidentally on plain axillary radiograph of the shoulders, shoulder pain has been reported in the literature (5 -10). Conservative treatment with muscle strengthening, stretching, anti-inflammatory medications, and steroid injections is the first option for symptomatic os acromiale. However, surgical treatment may be required if conservative treatment fails. Several surgical treatments, including excision by open or arthroscopic procedure, arthroscopic acromioplasty, and internal fixation with or without bone graft, have been described with mixed clinical outcomes (5-10). The optimal surgical option is therefore controversial.We present a case of unstable os acromiale in an elderly patient who was diagnosed with an impingement syndrome with intact rotator cuff. Unstable os acromiale was identified during arthroscopic examination. Retrospective review of the preoperative magnetic resonance imaging (MRI) and computed tomography (CT) arthrogram showed os acromiale between the meso-acromion and meta-acromion. Arthroscopic excision resolved the pain and improved the shoulder functions. Based on this case report, we recommend that clinicians include this pathology in the differential diagnosis of impingement syndrome of the shoulder. CASE REPORTA 73 -year -old, right-hand dominant woman presented with a 2 -month history of pain in the left shoulder with no history of trauma. The pain was described to be moderate in severity and was associated with active flexion and abduction, but not at rest. Physical examination showed that she had no limited range of motion, with active forward flexion to 170! , abduction to 170! , external rotation to 70! , and internal rotation up to the eighth thoracic spine with the arm on the side. Passive range of motion findings was the same as those during active range of motion. Neer's impingement sign was positive. Plain radiographs at that time were interpreted by the orthopedic surgeon as mild arthritic change in the glenohumeral joint (Fig. 1).The patient underwent physical therapy for 6 months, which failed to relieve the shoulder pain. Arthroscopic subacromial decompression was then planned. Moderate -grade chondrosis was noted in both the humeral head and glenoid surface of the glenohumeral joint. The long head of the biceps and the articular surface of the rotator cuff were normal. During examination of the subacromial bursa, abnormal mobility of the anterolateral acromion was seen. Retrospective review of the CT scan and MRI revealed the presence of os...
