Adhesive capsulitis of the shoulder, also known as frozen shoulder, is a condition characterised by thickening and contraction of the shoulder joint capsule and surrounding synovium. Adhesive capsulitis can rarely affect other sites such as the ankle .

粘連性肩關(guān)節(jié)囊炎 ，也稱凍結(jié)肩,，其特征是肩關(guān)節(jié)囊和周圍滑膜的增厚和攣縮,。粘連性關(guān)節(jié)囊炎很少影響其他部位，如踝關(guān)節(jié),。

Epidemiology

The incidence in the general population is thought to be 3-5%. Adhesive capsulitis typically affects women in the 5th to 6th decades of life, although patients with co-morbidities such as diabetes may develop the condition at earlier ages. The incidence in patients with diabetes is reported to be 2 to 4 times higher than in the general population.

流行病學(xué)

一般人群的發(fā)病率為3-5％,。粘連性關(guān)節(jié)囊炎通常見于50-60歲的女性，患有糖尿病等并發(fā)癥的患者發(fā)病年齡可能會提前,。糖尿病患者的發(fā)病率高于普通人群的2?4倍,。

Clinical presentation

Adhesive capsulitis presentation can be broken into three distinct stages:

• freezing: painful stage 

• patients may not present during this stage because they think that eventually, the pain will resolve if self-treated.

• as the symptoms progress, pain worsens and both active and passive range of motion (ROM) becomes more restricted

• this can eventually result in the patient seeking medical consultation

• typically lasts between 3 and 9 months and is characterised by an acute synovitis of the glenohumeral joint

• frozen: transitional stage

• most patients will progress to the second stage

• during this stage, shoulder pain does not necessarily worsen

• because of pain at end ROM, use of the arm may be limited causing muscular disuse

• can last between 4 to 12 months

• the common capsular pattern of limitation has historically been described as diminishing motions with external shoulder rotation being the most limited, followed closely by shoulder flexion, and internal rotation

• there eventually becomes a point in the frozen stage that pain does not occur at the end of ROM

• thawing stage

• begins when ROM begins to improve

• lasts anywhere from 12 to 42 months and is defined by a gradual return of shoulder mobility

臨床癥狀：

粘連性關(guān)節(jié)囊炎分為三個階段：

凝結(jié)期：疼痛期

• 患者在這個階段可能不會出現(xiàn)，因為他們認(rèn)為最終,，如果自我治療,，疼痛就會解決。

• 隨著癥狀的進(jìn)展,，疼痛惡化,，主動和被動的運(yùn)動范圍（ROM）變得更加受限制

• 這可能最終導(dǎo)致病人尋求醫(yī)療咨詢

• 通常持續(xù)3至9個月，其特征是盂肱關(guān)節(jié)的急性滑膜炎

凍結(jié)期：過渡期

• 大多數(shù)患者將進(jìn)入此階段

• 在這個階段,，疼痛并不一定會惡化

• 由于運(yùn)動時的疼痛,，手臂功能可能會受到限制，導(dǎo)致肌肉廢用

• 可持續(xù)4至12個月

• 常見的限制模式歷史上被描述為減少運(yùn)動,，外肩旋轉(zhuǎn)是最受限的,，其次是肩部屈曲和內(nèi)旋

• 最終在慢性期運(yùn)動受限成為一個點(diǎn)，在運(yùn)動范圍結(jié)束時不會發(fā)生疼痛

解凍期

• 開始時運(yùn)動范圍開始改善

• 持續(xù)12至42個月,，肩關(guān)節(jié)運(yùn)動逐步恢復(fù)

Pathology

Adhesive capsulitis is divided into two main types: 

• primary or idiopathic

• absence of preceding trauma

• secondary 

• major or minor repetitive trauma

• shoulder or thoracic surgery

• endocrine, e.g. diabetes, hyperthyroidism 

• rheumatological conditions

病理

粘連性關(guān)節(jié)囊炎分為兩大類：

原發(fā)性或特發(fā)性

•   無外傷病史

繼發(fā)性

• 重大或輕微的重復(fù)創(chuàng)傷

• 肩部或胸部手術(shù)

• 內(nèi)分泌,，例如糖尿病,，甲狀腺功能亢進(jìn)

• 風(fēng)濕病

Radiographic features

MRI/MR arthrography

• normal inferior glenohumeral ligament measures <4 mm and is best seen on coronal oblique images at the mid glenoid level; in adhesive capsulitis, the axillary recess may show thickening ≥1.3 cm

• joint capsule thickening 

• abnormal soft tissue thickening within the rotator interval with signal alteration

• abnormal soft tissue encasing the biceps anchor

• variable enhancement of the capsule and synovium within the axillary recess and rotator interval

Other MR arthrography features include

• thickening of the coracohumeral ligament (CHL) 

• subcoracoid triangle sign 

影像學(xué)表現(xiàn)

MRI / MRI關(guān)節(jié)造影

• 正常下盂肱韌帶測量值<4毫米，在斜冠位上關(guān)節(jié)囊中間層面顯示最好,；在粘連性關(guān)節(jié)囊炎患者中,，腋隱窩軟組織增厚≥1.3厘米

• 關(guān)節(jié)囊增厚

• 肩袖間隙異常軟組織增厚伴信號異常

• 異常軟組織包繞肱二頭肌腱

• 增強(qiáng)后腋隱窩和肩袖間隙的關(guān)節(jié)囊或滑囊強(qiáng)化

其他MR關(guān)節(jié)造影包括

• 喙肱韌帶（CHL）增厚

• 喙突下三角征

• 腋囊正常容量15-18ml，本病小于10ml,，多數(shù)小于5ml（文獻(xiàn)上）

Treatment and prognosis

Adhesive capsulitis is typically a self-limiting disease that improves over 1-2 years. Treatment options include:

• physiotherapy

• corticosteroid injections

• glenohumeral hydrodilatation

• closed manipulation under anaesthesia

• arthroscopic capsular release with lysis of adhesions
