“…Bankart (1938) stated that disruption and detachment of the anterior-inferior capsule from the glenoid was mainly responsible for on-going instability after shoulder dislocation. Now, the key role of the IGHL in shoulder joint stability is widely accepted (Turkel et al, 1981;Branch et al, 1995;Steinbeck et al, 1998;McMahon et al, 1999;Jobe, 2000;Levine and Flatow, 2000;McMahon et al, 2001;Urayama et al, 2001;Burkart and Debski, 2002). Therefore, many surgical procedures advocate its reconstruction to recover normal joint stability (Neer and Foster, 1980;Bigliani et al, 1994;Matsen et al, 2000;Choi and Ogilvie-Harris, 2002;Lephart et al, 2002;Gill and Zarins, 2003).…”

“…Since 1829 when the capsulolabral complex of the shoulder was first described by Flood, many reports have demonstrated its biomechanical relevance (Branch et al, 1995;Levine and Flatow, 2000;Urayama et al, 2001;Burkart and Debski, 2002;Steinbeck et al, 2003). Innervation of the shoulder joint capsule has also been widely described (Gardner, 1948;Testut, 1979;Loomer and Graham, 1989;Williams et al, 1995;Aszmann et al, 1996;Jobe, 2000;Ball et al, 2003).…”

Although the Inferior Glenohumeral Ligament (IGHL) has a well known mechanical and proprioceptive relevance in shoulder stability, the interrelation of the ligament's anatomical disposition/innervation has not actually been described previously. The purpose of the study was to determine the IGHL innervation patterns and relate them to dislocation. Forty-five embalmed and 16 fresh-frozen human cadaveric shoulders were studied. Masson's Trichrome staining detailed the intraligamentous nerve fiber arrangements. The effect on the articular nerves of an anteroinferior dislocation of the shoulder joint and the position of 60 degrees abduction and 45 degrees external rotation was studied dynamically. The axillary nerve provided IGHL innervation in 95.08% of the cases. We saw two distinct innervation patterns originating from the axillary nerve. In Type 1, one or two collaterals diverged later from the main trunk to enter the ligament. Type 2 showed innervation to the ligament provided by the posterior branch for three to four neural branches. In both cases, these branches enter the ligament near the glenoid rim and at the 7 o'clock position (right shoulder). The radial nerve (Type 3 innervation pattern) provided IGHL innervation in 3.28% of the cases. Microscopic analysis revealed wavy intraligamentous neural branches. The articular branches relaxed and separated from the capsule at the apprehension position and stayed intact after dislocation. These results showed a special predisposition to avoid possible denervation and suggested that the neural arch probably remains unaffected after most dislocations. Knowledge of the neural anatomy of the shoulder will clearly help in avoiding its injury in surgical procedures.

“…This is considered to be the reference length of the cadaveric muscles. 21 Therefore, we defined the elbow at 45 flexion, neutral forearm rotation, and neutral wrist flexion as the standard and starting position. The strain on each muscle fiber in the standard position was set as 0%.…”

“…5,12,13,20,24,25 The ABER position of the shoulder places stress on the inferior capsular pouch and anterior labroligamentous complex, which are important structures for maintaining anterior shoulder stability. 1,18,22 Placing tension on the anterior labroligamentous complex might increase the accuracy of MRI in the detection of Bankart lesions. However, little is known about MRI of Bankart lesions under tension, and quantitative comparison between the neutral, nonrotated position and ABER has not been performed.…”
