This post looks at denervation of the Axillary Nerve in Quadrilateral Space Syndrome and Axillary nerve damage post shoulder dislocation both of which are less common causes of denervation around the shoulder Quadrilateral space syndrome (QSS) is a rare disorder characterized by axillary nerve and posterior humeral circumﬂex artery (PHCA) compression within the quadrilateral space, ﬁrst described by Cahill and Palmer in 1983 [1-5]. Cahill originally described four distinct features of QSS: (1) diffus
Diagnosis is clinical with point tenderness over the quadrilateral space and possible presence of teres minor atrophy. MRI studies may show axillary nerve compression. Treatment involves a course of NSAIDs, activity modification and physical therapy with surgical decompression indicated in refectory cases MRI is an indispensable tool for the evaluation of rotator cuff and labral pathology at the shoulder. It is equally effective in diagnosing other surgically correctable causes of shoulder pain, which may clinically mimic a rotator cuff tear. Quadrilateral space syndrome results from axillary nerve compression, most commonly caused by. Quadrilateral Space Syndrome. Quadrilateral space syndrome involves compression of the axillary nerve and/or the posterior circumflex artery within the quadrilateral space. This space is defined by the teres minor superiorly, long head of the triceps medially, humerus laterally, and teres major inferiorly. (MRI) may demonstrate a space. Magnetic resonance imaging (MRI) confirmed the dilated PCHA without any other space-occupying lesion . Quadrilateral space syndrome (QSS) with axillary nerve entrapment was suspected. US-guided diagnostic axillary nerve block using 2 mL 1% xylocaine was performed . She had immediate partial pain relief after the injection and later on reported.
The axillary nerve was visualized entering the quadrilateral space which, although, was severely narrowed secondary to the large osteophyte. The patient's clinical symptoms and MRI findings were consistent with quadrilateral space syndrome The axillary neurovascular bundle within the quadrilateral space can be defined on oblique sagittal T1-weighted images. In quadrilateral space syndrome, MRI may show signal alteration or atrophy of the teres minor muscle with or without involvement of the deltoid muscle (Figure 5) [ Quadrilateral space syndrome is a rare disorder characterized by compression of the axillary nerve and posterior humeral circumflex artery within the quadrilateral space 1). The quadrilateral space is located posterior and inferior to the glenohumeral joint and contains the axillary nerve and posterior humeral circumflex artery Quadrilateral space syndrome (QSS) is compression of the axillary nerve and posterior humeral circumflex artery as they pass through this space. This is a vary rare condition, but should be suspected in athletes with the symptoms below . Sometimes the symptoms are caused by the compression of an artery in the same area. Quadrilateral space syndrome usually happens from overuse, especially with overhead sports like throwing and swimming

This article illustrates the common denervation syndromes that involve the shoulder girdle: Parsonage-Turner syndrome, quadrilateral space syndrome, and suprascapular neuropathy. By demonstrating the exact muscles involved and spared, MRI non-invasively identifies the level of nerve insult in the neuraxis Introduction. Ultrasound (US) is a largely available, cost-effective and innocuous technique to assess the brachial plexus. US can be considered as an alternative to Magnetic Resonance Imaging (MRI) in all clinical settings in which MRI is contraindicated, not readily available or in case of claustrophobia .US can be used for the assessment of the brachial plexus in case of trauma, tumours.
SUMMARY: With advancement in 3D imaging, better fat-suppression techniques, and superior coil designs for MR imaging and the increasing availability and use of 3T magnets, the visualization of the complexity of the brachial plexus has become facile. The relevant imaging findings are described for normal and pathologic conditions of the brachial plexus Hypothenar hammer syndrome with a thrombosed ulnar artery aneurysm and the pathognomonic corkscrew appearance of the superficial ulnar artery. The thrombosed aneurysm and the diseased portion of the ulnar artery were subsequently resected (4a). An interposition vein graft was placed between the distal ulnar artery and the superficial. Quadrilateral space syndrome is seen in overhead sports that require repetitive throwing actions. This represents a chronic compression syndrome of the axillary nerve (24). This syndrome develops due to the close proximity of the teres minor to the quadrilateral space. Teres minor forms the superior margin of the quadrilateral space

It is not uncommon for the diagnosis of quadrilateral space syndrome to be suggested by an MRI performed to examine for other causes. In a prospective investigation, isolated teres minor atrophy was identified in 12 out of 217 patients (5.5%) who underwent consecutive shoulder MRI examinations over a 3-month period of time Compression of the neurovascular bundle within this space, termed the quadrilateral space syndrome by Cahill and Palmer in 1983, can occur from anomalous fibrous bands, traumatic scarring, mass lesions, glenolabral cysts, large humeral head osteophytes, and/or muscle hypertrophy [47-51] Axillary neuropathies are due to traumatic injuries, traction injuries, quadrilateral space syndrome, and brachial neuritis (also called neuralgic amyotrophy or Parsonage-Turner syndrome).  An anterior dislocation and forced abduction of the shoulder joint appear to be common causes of axillary nerve injury in young people ^ a b Cothran, R. Lee; Helms, Clyde (2005-03-01). Quadrilateral space syndrome: incidence of imaging findings in a population referred for MRI of the shoulder Neuralgic amyotrophy (NA), also known as Parsonage-Turner syndrome, is characterised by sudden pain attacks, followed by patchy muscle paresis in the upper extremity. Recent reports have shown that incidence is much higher than previously assumed and that the majority of patients never achieve full recovery. Traditionally, the diagnosis was mainly based on clinical observations and treatment.

Although the teres minor has received little attention in the literature, it is an important component of shoulder function. Most reports of the teres minor are described only as traumatic injuries to the musculotendinous unit or as neurologic lesions of the posterior branch of the axillary nerve in quadrilateral space syndrome This is the wiki of Quadrilateral space syndrome. Cause Diagnosis. Diagnosis is usually suspected by clinical history and confirmed by MRI, in which edema of the teres minor is seen, with variable involvement of the deltoid.The circumflex humeral artery may also be compressed. Before the advent of MRI, compression of this vessel on angiography used to be the mechanism of diagnosis, although. circumflex artery. Fibrous bands, cysts of the glenoid labrum, lipoma or dilated veins can occupy the quadrilateral space pathologically.

These can present as an impingement syndrome with pain on overhead activity . In quadrilateral space syndrome, the contents within the quadrangular space are compressed, leading to vague symptoms of shoulder pain and teres minor denervation [4,8]. Diagnosis is confirmed using MRI to observe the denervation changes on the teres minor Quadrangular (or quadrilateral) space syndrome (QSS) can occur secondary to various compressive pathologies. Although the incidence of such pathologies is rare, QSS has a known predilection for subgroups of athletic populations and can often suffer misdiagnosis or are clinically under-appreciated Quadrilateral space syndrome (QSS) is a rare condition where the axillary nerve of PHCA are compressed within the quadrilateral space. This compression is most commonly due to the development of fibrous bands or increased muscle size and bulk (hypertrophy) of the muscles that form the boundaries of the quadrilateral space.
