o Posterior and multidirectional instability represent a spectrum of disease encompassing posterior instability with
dislocation, posterior unidirectional instability with recurrent posterior subluxation, bidirectional instability with
posterior and inferior subluxation, and multidirectional instability with global laxity.
o Nonoperative approaches are the mainstay of treatment for most cases.
o History and physical examination, especially examination under anesthesia, are critical to selecting the proper diagnosis
and treatment, as imaging studies are often nondiagnostic.
o Arthroscopic approaches allow a thorough evaluation of
intra-articular pathology and a pathology-specific treatment approach.
o Arthroscopic treatment allows the surgeon to address labral tears, capsular laxity, capsular tears, and the rotator interval.
o Open procedures may be preferred in cases of bone loss and in certain revision cases.

Posterior and multidirectional shoulder instability represent a spectrum of disease from posterior instability
with dislocation to posterior unidirectional instability with recurrent posterior subluxation, bidirectional instability
with posterior and inferior laxity, and multidirectional instability with global laxity. Posterior instability is
uncommon, representing approximately 5% of all glenohumeral instability. However, more subtle cases of posterior
subluxation or multidirectional instability are likely often undiagnosed. Classically, these patterns of instability
have been treated with an open surgical approach
(1). However, arthroscopic techniques have progressed to the point where they are an excellent option for treating
these conditions. This chapter will review the diagnosis and treatment of posterior and multidirectional instability
with an emphasis on arthroscopic surgical techniques.

o 肩关节的向后和多向不稳定可发展为一系列的疾病,包括:向后脱位型不稳定症、频发的向后单一方向半脱位不稳定症、

向后下方半脱位型双向不稳定症、全球松弛的多方向不稳定症。

o 大多数情况下,非手术疗法是现行的主要治疗手段。
o 鉴于成像观察通常无法进行诊断,病史检查和身体检查(尤其是麻醉下的身体检查)对于明确诊断和选择合适的治疗方法相当关键。
o 应用关节镜技术可以全面评估关节内病理和针对该病理所采取的具体治疗方法。
o 骨科医生可以利用关节镜明确诊断出盂唇撕裂、关节囊松弛、关节囊破裂和肩袖间隙。
o 对于出现骨块缺失和一些需进行手术修正的案例,可首选开放式手术进行治疗。

肩关节的向后和多向不稳定可发展为一系列的疾病,从向后脱位型不稳定到频发的向后单一方向半脱位不稳定、后下方松弛的双向不稳定、

以及全球松弛的多方向不稳定。肩关节向后不稳定不常见,大约占所有盂肱处不稳定症的5%。然而,有一些更加隐匿的关节向后半脱位或

多向不稳定的情况常无法被确诊出来。治疗此类关节不稳定症的惯用方法为开放性外科手术(1)。但是,关节镜技术已经发展成为有效治

疗此类不稳定症的一个很好的治疗手段。本章将回顾肩关节多向和向后不稳定症的诊断和治疗,着重介绍关节镜外科技术。
