为何建议进行此手术

Mater Private Hospital Rockhampton 的上肢外科医生 Kieran Hirpara 医生会从适合您病情的最微创方案开始。患者通常由其全科医生(GP)转诊至我们的诊所;如果理疗师建议您就诊,您仍需获得全科医生的转诊才能符合 Medicare 报销资格。在您的预约就诊中,我们会采集病史,检查您的肩部,并在必要时安排影像学检查,以查明导致您疼痛的原因。

此手术会切除锁骨远端的一小块骨头,位于锁骨与肩胛骨上端相接的关节处。我们通常在非手术治疗(如活动调整和物理治疗)未能缓解疼痛,且该关节出现磨损或损伤时建议进行此手术。该手术适用于肩部稳定且维持锁骨位置的韧带完整的患者。手术旨在缓解疼痛并改善肩部的活动与功能。

术前

在您的手术之前,我们将确认影像学检查(如X光、MRI或超声)显示了导致您疼痛的原因,并有助于制定手术方案。手术当天,您需要在手术时间前七小时停止进食和饮水。我们要求七小时而非六小时,以便如果手术室排班提前结束,我们可以将您的手术提前安排。您的外科医生会告诉您哪些常规药物需要停用,哪些需要继续服用,因此请携带一份您服用的所有药物的书面清单,包括任何抗凝药物。请安排他人在术后开车送您回家,因为您将无法自行驾驶。请穿着宽松、舒适且易于穿脱的衣物。如果您有其他健康状况,可能需要进行血液检查或由麻醉师进行评估。

手术当天

您将抵达医院的手术入院单元,在此办理入院手续并进行术前准备。术前您将与麻醉师会面并讨论手术方案。本手术在全身麻醉联合区域神经阻滞下进行。麻醉师将在术前与您会面,并详细说明这两部分麻醉方案。

随后,您将被带入手术室进行手术。术后,您将在复苏区苏醒,护士会在此监护您直至麻醉消退。待生命体征平稳后,根据手术类型及恢复情况,您将被转入病房或直接回家。

手术内容

这是一种微创手术。您的外科医生会在肩部周围做几个小切口,包括后侧的一个,并将一个小摄像头插入体内,以便在屏幕上观察关节。通过这些小切口,医生会从锁骨远端切除约 5 毫米的骨骼,切除量刚好足以使粗糙、磨损的表面不再相互摩擦。医生会小心地切除受控量的骨骼,因为切除过多可能会削弱锁骨并导致关节不稳定。

固定锁骨位置的韧带将保持原样。您的外科医生在操作过程中还会检查并保护关节上方的软组织。

骨骼切除后,小切口将以缝合方式关闭,并覆盖敷料。

术后

大多数患者在此手术后需在医院过夜,但部分患者可能当天即可出院。您将在恢复区苏醒,随后转入病房,护士会密切观察您的情况并根据需要为您镇痛。您的手臂将佩戴简易吊带以提供舒适感;清洗和进行锻炼时需取下吊带。回家后最初的24小时内,应有人陪同您。我们通常保留敷料约10天;除非我们告知您,否则请勿在此之前自行拆除。我们会在复诊时为您更换或拆除敷料。您从第一天起即可在家中活动,但动作需轻柔。您至少六周内不得驾驶;一旦外科医生允许您驾驶(通常在六周复查时),请参阅上肢手术后驾驶。

恢复

在最初几天,您的肩部会感到疼痛和肿胀,手术室中实施的神经阻滞麻醉效果会逐渐消退。止痛、休息和冰敷有助于缓解这些症状。随着肿胀消退,不适感通常会在最初的一两周内逐渐减轻。

您的手臂会佩戴一个简单的吊带以提供舒适感。在洗澡和进行锻炼时,您需要取下吊带。物理治疗师最初会指导您进行轻柔的活动,随后随着肩部的恢复情况,逐步增加强度直至恢复正常使用。从第一天起,您就可以在家中走动,但动作要轻柔。在早期,直立睡眠或用枕头支撑通常更舒适,许多人最初发现在椅子或躺椅上睡觉更容易。

日常任务需要稍作规划。起初,您无法用手术侧手臂提起重物,在肩部活动更加自如之前,您需要在穿衣和洗头等方面寻求帮助。一旦肿胀消退且活动能力恢复,日常活动会逐周变得更容易。驾驶恢复较晚:您至少六周内不能驾驶,一旦外科医生在通常的六周复查时为您解除限制,请参阅上肢手术后的驾驶。返回工作的时间取决于您的工作性质,外科医生会与您详细讨论此事。

每个人的恢复情况各不相同。您的时间表可能有所不同,外科医生和物理治疗师将在整个过程中为您提供指导。

可能出现的问题

大多数患者恢复良好,但偶尔也可能出现问题。您的外科医生和医疗团队会密切监测您的状况,以便尽早发现任何问题。

最常见的问题是疼痛未能缓解。如果切除的骨骼略多或略少,就可能出现这种情况。您可能会注意到肩部顶端在最初几周后持续存在深层酸痛,或者在手臂横过身体时出现卡顿感。如果疼痛未按预期缓解,请在复诊时告知医生。

有时,锁骨末端可能会重新生长。如果发生这种情况,粗糙的表面可能会再次相互摩擦,导致疼痛复发。您会注意到与最初促使您接受手术相同类型的酸痛。如果这种情况听起来很熟悉,请在随访时告知我们。

切除过多的骨骼,或干扰固定锁骨的韧带,可能导致关节不稳定。您可能会感觉到锁骨在皮肤下移动、发出咔哒声或移位,或者感觉肩部不够稳固。如果您之前曾有过锁骨与肩胛骨分离的损伤,这一点尤为重要。在手术前,请告诉您的外科医生任何此类既往损伤,因为这可能会改变治疗方案。

较少见的情况下,还可能出现其他问题。这些包括感染、僵硬、骨折、关节自行融合,以及一种称为复杂区域疼痛综合征的持续性疼痛状况。感染的迹象包括伤口周围扩散的红肿、肿胀加剧或发热。如果您注意到这些症状,请立即致电诊所。关节在微创手术后也可能脱位,这会导致突然的疼痛和肩部形状可见的变化。如果发生这种情况,请立即寻求紧急护理。

本页上的并发症表列出了典型的发生率,如果您想了解具体数据,可以参考该表。

何时联系我们

如果您出现发热,伤口发红或渗出液情况加重,或疼痛突然比预期明显加剧,请立即致电诊所。如果您的小腿出现肿胀或疼痛,出现呼吸困难,或手臂无法感知或活动,请前往急诊。这些症状需要立即检查。如果您感觉有任何异常但不确定,请致电我们。我们更希望尽早了解情况。

Evidence & references

This is the clinical evidence summary written for health professionals. It is technical, and it lists the research this page was built from. You do not need to read it to understand your treatment or to make a decision about it.

Overview

  • In appropriately selected patients, open or arthroscopic distal clavicle resection is necessary to relieve symptoms [9].
  • A well-performed distal clavicle excision will likely perform better than a poorly performed one, regardless of whether an open or arthroscopic approach is chosen [1].
  • Arthroscopic and open distal clavicle excisions both provide significant pain reduction at 1 year with no significant difference in outcome measures between groups, except for VAS pain score improvement [10].
  • Arthroscopic distal clavicle resection has provided more 'good or excellent' results than has the open procedure, but is comprised of low-level evidence [2].
  • Among patients undergoing distal clavicle excision for acromioclavicular joint pathology, those having an arthroscopic procedure, specifically through the direct approach, can expect a faster return to activities while obtaining similar long-term outcomes compared with the open procedure [3].
  • Simple excision of the outer end of the clavicle has yielded satisfactory results in patients with complete dislocation and subluxation of the acromioclavicular joint, with no residual upward displacement disturbing the patients [4].
  • Excision of the outer end of the clavicle is preferred for old dislocations, while open reduction and internal fixation are not recommended due to complications and poor functional results [16].
  • Incomplete excision and regrowth of the distal clavicle are the most common causes of revision [6].
  • Although distal clavicle excision with 2.5 mm of bone was successful in many specimens, a 5 mm resection guaranteed no bone-to-bone abutment [11].
  • The use of intraoperative ultrasound and cannulated dilators allows surgeons to perform distal clavicle excisions in a more efficient, reproducible and safer manner [7].
  • Regardless of the technique chosen for distal clavicle resection, portal placement remains paramount in both facilitating surgery and avoiding injury to adjacent extra-articular structures [8].

Anatomy & Pathophysiology

Bony Anatomy

  • The clavicle is the first bone to ossify, occurring in the fifth week of gestation [35].
  • The clavicle is the only long bone to ossify by intramembranous ossification [35].
  • The medial (sternal) epiphysis of the clavicle is the last ossification center to fuse, occurring at age 20 to 25 years [35].
  • The primary blood supply to the clavicle is periosteal, and no nutrient artery is present [35].
  • The scapula has only one true diarthrodial articulation, the acromioclavicular (AC) joint [35].
  • The scapula is attached to the axial skeleton by the acromioclavicular (AC) and sternoclavicular (SC) joints [34].
  • The scapula is separated from the chest wall by thin gliding fibro-fatty tissue, allowing smooth excursion over the chest wall [34].
  • The scapular spine is an osseous ridge that separates the supraspinatus and infraspinatus fossae [35].
  • The acromion has three ossification centers: the metacromion (base), the mesoacromion (middle), and the preacromion (tip) [35].
  • Failure of fusion of the acromial ossification centers results in os acromiale [35].
  • The subchondral bone of the glenoid is relatively flat, with articular concavity augmented by cartilage and a circumferential labrum [35].
  • The glenoid averages 5° of retroversion in relation to the axis of the scapular body [35].
  • The coracoid process serves as the origin for the coracobrachialis muscle and the short head of the biceps tendon [35].
  • The pectoralis minor muscle inserts onto the medial coracoid process [35].

Ligaments and Joint Stability

  • The AC joint is a small diarthrodial joint with an interposed fibrocartilaginous disk [35].
  • The superior and posterior AC ligaments are the primary stabilizers to anterior and posterior (horizontal) translation of the clavicle [35].
  • The coracoclavicular ligaments (conoid: medial; trapezoid: lateral) are the primary stabilizers to superior (vertical) translation of the distal clavicle [35].
  • The superior shoulder suspensory complex (SSSC) provides a stable connection between the scapula and the axial skeleton [35].
  • The SSSC is composed of the glenoid, the coracoid process, the coracoclavicular ligaments, the distal clavicle, the AC joint, and the acromion [35].
  • The superior strut of the SSSC comprises the middle clavicle [35].
  • The inferior strut of the SSSC comprises the lateral scapular border and spine of the scapula [35].
  • The trapezoid and conoid ligaments have unique functions in normal shoulder kinematics due to their anatomic attachments [47].
  • Kinematic changes associated with AC joint dislocation can be a potential source of pain and dysfunction in the shoulder [48].
  • Scapular and clavicular kinematics are affected in AC separation models [50].

Pathophysiology and Injury Patterns

  • A type I AC injury is an isolated sprain of the AC ligaments with no clinical deformity and normal radiographs [87].
  • A type II AC injury consists of a complete tear of the AC ligaments and a sprain of the CC ligaments [87].
  • In a type II AC injury, the radiograph shows a more vertical translation of the CC interval (<25%) compared with that of the uninjured shoulder [87].
  • The normal coracoclavicular distance measures approximately 1.1 to 1.3 cm [87].
  • Injury to the AC ligaments in type II injuries causes AP instability of the AC joint, resulting in an increase of 3.6 mm in anterior and 6.4 mm in posterior translation [87].
  • In most patients, the horizontal instability present in type II injuries remains asymptomatic, but long-term problems with AC joint pain are not uncommon [87].
  • A type III AC injury involves dislocation secondary to complete disruption of the AC and CC ligaments [87].
  • A type III AC injury creates increased vertical translation of the CC distance (25% to 100%) compared with that of the uninjured shoulder [87].
  • Type I and II acromioclavicular joint disruptions impair long-term shoulder function in about half of patients 10 years after injury [63].
  • Fractures of the clavicle distal to the coracoclavicular ligament have a reputation for failing to unite when treated with methods similar to other clavicle fractures, such as a figure-of-eight bandage or a Billington yoke [28].
  • Distal clavicle excision (Mumford procedure) must be reserved for patients in whom the CC ligaments are intact and there is no concomitant instability [12].
  • When horizontal or vertical instability exists, results of distal clavicle excision are compromised because the technique does not address instability and may accentuate it [12].

Classification

  • Fractures of the clavicle are divided into three groups: Group I (middle third), Group II (distal to the coracoclavicular ligament), and Group III (proximal end) [28].
  • Fractures of the clavicle distal to the coracoclavicular ligament are classified by Neer into two types [28].
  • Multiple classifications for lateral end of clavicle fractures exist, including those of Allman, Craig, and Neer [73].
  • Robinson classified clavicular injuries and defined the lateral one-fifth of the clavicle as Type 3 [73].
  • The Rockwood classification defines Type I as 0% to <10% superior displacement of the distal clavicle [83].
  • The Rockwood classification defines Type II as 10% to ≤25% superior displacement of the distal clavicle [83].
  • The Rockwood classification defines Type III as >25% to ≤100% superior displacement of the distal clavicle [83].
  • The Rockwood classification defines Type V as >100% superior displacement of the distal clavicle compared with the contralateral side [83].
  • A new classification of AC joint instability defines Group 1 as a coracoclavicular distance difference (CCD) ≤30% compared with the contralateral side [83].
  • A new classification of AC joint instability defines Group 2 as a coracoclavicular distance difference (CCD) >30% compared with the contralateral side [83].
  • Group 1 in the new AC joint instability classification includes all Rockwood type I, type II, and borderline low-grade type III patients [83].
  • Group 2 in the new AC joint instability classification represents high-grade AC joint dislocations, including all Rockwood type V patients and the majority of Rockwood type III patients [83].
  • The Rockwood Type IV AC injury includes disruption of AC ligaments, disruption of coracoclavicular ligaments, and posterior translation of the clavicle [31].

Clinical Presentation

  • Patients with displacement greater than 100% of the thickness of the distal clavicle had poorer postoperative clinical outcomes [5].
  • Horizontal instability of the clavicle is evident with distal clavicle resection of greater than 10 mm [14].
  • Methods to diagnose both superior and posterior translation of the clavicle need further debate [22].
  • Clinical examination and surgical treatment should address anatomic restoration of individual structures to optimize the mechanical capability of the claviscapular segment [23].

Investigations

Imaging and Diagnostic Assessment

  • Standardized plain films are almost always sufficient to garner the information needed for shoulder care, and the temptation to "overimage" should be resisted [19].
  • The purpose of imaging the shoulder is to help establish the diagnosis, determine the severity of the pathoanatomy, assist in surgical planning, and enable the surgeon to illustrate the condition of the shoulder to the patient [19].
  • At least two X-ray views should be obtained for shoulder imaging: an anteroposterior in the plane of the glenoid and an axillary projection with the arm in abduction [42].
  • Weighted stress radiographs significantly increased the measured elevation of the clavicle and the coracoclavicular distance compared with non-weighted views [89].

Intraoperative Imaging and Technique

  • Intraoperative use of ultrasound and cannulated dilators allows surgeons to perform distal clavicle excisions in a more efficient, reproducible, and safer manner [7].

Resection Parameters and Biomechanics

  • A 5-mm distal clavicle resection guaranteed no abutment but decreased joint stiffness [29].

Treatment

Indications and Contraindications

  • Distal clavicle excision must be reserved for patients in whom the coracoclavicular ligaments are intact and there is no concomitant instability [12].
  • Clavicular resection reliably produced significant improvement in patients with persistent pain or posttraumatic arthritis [15].

Comparative Outcomes: Open vs. Arthroscopic

  • Both the direct superior approach and the indirect subacromial approach to the arthroscopic distal clavicle resection result in successful clinical outcome with clinically insignificant difference at final follow-up [57].

Surgical Technique and Biomechanics

  • The slight increase in the in situ graft force only in the posterosuperior and posterior direction after distal clavicle excision suggests only a marginal protective role of the acromioclavicular articulation [81].

Historical and Alternative Procedures

  • Simple excision of the outer end of the clavicle has yielded satisfactory results in patients with complete dislocation and subluxation, with no residual upward displacement disturbing the patients [4].
  • The new operative procedure described in 1972 combines resection arthroplasty with fixation of the clavicle in an anatomical position [13].

Complications

  • Persistent pain is the most common complication of distal clavicle resection, potentially resulting from over- or under-resection [78].
  • Incomplete resection can occur due to poor visualization [78].
  • To prevent under-resection, the acromioclavicular joint should be viewed via an anterior and lateral portal [78].
  • Overexuberant resection of the clavicle or disruption of the acromioclavicular and coracoclavicular ligamentous system can result in iatrogenic instability of the acromioclavicular joint [78].
  • Posterior translation of the acromioclavicular joint is increased by 32% after a distal clavicle resection with an acromioclavicular capsular incision [78].
  • Acromioclavicular joint resection alone should be cautioned in patients with prior acromioclavicular joint instability injuries, as prior capsular or ligamentous disruption may lead to greater instability after resection [78].
  • In cases of prior instability, acromioclavicular resection combined with acromioclavicular ligament reconstruction may be needed [78].
  • Posterior translation can be reduced to 13% if the distal clavicle resection is completed with a coracoacromial ligament augmentation procedure [78].
  • Postoperative iatrogenic instability may require revision surgery or coracoclavicular ligament reconstruction [78].
  • Other complications of distal clavicle resection include infection, stiffness, fracture, spontaneous fusion, and complex regional pain syndrome [78].
  • A 5 mm resection guaranteed no bone-to-bone abutment in a cadaver model, whereas 2.5 mm resection was successful in many specimens [11].
  • Portal placement remains paramount in facilitating surgery and avoiding injury to adjacent extra-articular structures regardless of the technique chosen for distal clavicle resection [8].

Contraindications and Selection Factors

  • When horizontal or vertical instability exists, results are compromised because the technique does not address instability and may accentuate it [12].

Outcomes and Efficacy

  • Arthroscopic distal clavicle resection has provided more 'good or excellent' results than the open procedure, but is comprised of low-level evidence [2].
  • Patients undergoing arthroscopic distal clavicle excision through the direct approach can expect a faster return to activities while obtaining similar long-term outcomes compared with the open procedure [3].
  • In carefully selected patients with isolated acromioclavicular joint pathology, arthroscopic distal clavicle excision results in statistically and clinically significant improvements in range of motion and patient-reported outcome measures [17].
  • Simple excision of the outer end of the clavicle has yielded satisfactory results with no residual upward displacement disturbing the patients [4].

Incidence and Demographics

  • 10 of 894 (1.1%) rotator cuff repairs underwent subsequent distal clavicle resection [30].
  • Older patients and females were more likely to experience postoperative complications requiring reoperations, including revision acromioclavicular joint reconstruction, distal clavicle excision, and irrigation and debridement [96].

Recovery

  • Arthroscopic distal clavicle excision through the direct approach allows for a faster return to activities compared with the open procedure [3].
  • More than 90% of patients manage to return to driving within 4 weeks following arthroscopic subacromial decompression and acromioclavicular joint excision [59].
  • More than 90% of patients manage to return to work within 6 weeks following arthroscopic subacromial decompression and acromioclavicular joint excision [59].
  • Partial claviculectomy offers rapid return to function for chronic symptomatic injuries [24].
