Rhomboid minor originates from the inferior end of the ligamentum nuchae and spines of the seventh cervical and first thoracic vertebrae (Standring 2016). It attaches to the medial border of the scapula at the root of the scapular spine (Standring 2016).

Atrophy of the deltoid, supraspinatus, infraspinatus and the intrinsic muscles of the hand are especially easy to detect on physical examination (Figure 12.1). Deltoid atrophy will manifest itself as loss of bulk over the shoulder. The injured shoulder may appear lower than the uninjured side. Atrophy of the supraspinatus and infraspinatus can be seen as a hollowing out of the musculature overlying the scapula with increased prominence of the scapular spine. Inspection of the hand should include inspecting the bulk of the thenar muscles as well as the interossei. The thenar musculature should form a convex surface but can become concave in cases of atrophy. Atrophy of the interossei will manifest itself as hollowing out of the spaces between the metacarpals with increased prominence of the metacarpal bones. Clawing of the ring and little fingers is indicative of intrinsic dysfunction.

A blunt trocar is introduced into the viewing portal and directed towards the infraspinatus fossa. The tissue under the spine of the scapula is swept away, feeling the curvature of the roof of scapular spine to ensure visualization. The trocar is then progressively directed towards the working portal, passing the suprascapular nerve before falling into the spinoglenoid notch.

Complex scapular fractures are operated via the Judet posterior approach in which the skin incision is made along the scapular spine and curved caudally along the medial edge of the scapular body. Then, the infraspinatus muscle is detached from the floor of the infraspinous fossa [11,23]. Therefore, we used the same approach in our study. The circumflex scapular artery, a branch of the subscapular artery, is the only structure (with accompanying veins) passing through the triangular space [12]. It then runs on the ventral surface of the infraspinatus muscle. After the mobilization of the IB-SSN, this vessel can be therefore used as a guiding structure for dissecting the ‘tunnel’ from the infraspinous fossa into the triangular space [12] (formed by teres minor and major muscles and long head of the triceps). For approaching this space, it is recommended to cut the skin between the teres muscles. Therefore, we propose to make a U-shaped skin incision for LSN – IB-SSN nerve transfer (Figure 7). In revision cases after previous orthopaedic procedure for scapular fracture performed via the Judet approach, the incision should follow the primary cut and then be prolonged caudo-laterally parallel to the scapular spine.

The patient was placed in the lateral decubitus position according to the selected site of surgical intervention. After sterilization and drapping of the skin of the upper back, counting down from seventh cervical vertebrae spine to identify the spine of the seventh thoracic vertebrae (T7). This was related to the tip of the scapular spine. A high-frequency probe of Sonosite M Turbo ultrasonography (FUJIFILM sonosite, Inc., Bothell, WA, USA) was placed across the T7 spine and the probe was moved laterally to identify the transverse process of T7. Thereafter, the probe was moved to a sagittal plane to visualize the erector spinae muscles lying underneath the trapezius muscle. A 22-gauge, 80 mm needle (Stimuplex D, B-Braun, Germany) was inserted medially in-plane relative to the ultrasound probe and directed towards the transverse process. Once the needle was underneath the anterior fascia of the erector spinae muscle (Figure 2), 1 ml normal saline was injected for hydro-dissection sign to verify the needle tip, and then a volume of 0.3–0.4 ml/kg 0.25% bupivacaine with a maximum volume of 30 ml was injected under the erector spinae muscle into the newly formed space [19].

The anterior drawer test can detect insufficiency of the anterior capsular mechanism and is best performed with the patient lying supine and the ipsilateral scapula supported by the bed. Gerber et al first described this technique with the affected shoulder held in 80° to 120° of abduction, 0° to 20° of forward flexion, and 0° to 30° degrees of external rotation. The examiner places the middle and index finger on the scapular spine and thumb on the coracoid process to control scapular motion. The other hand then grasps the patients relaxed arm at the humeral head and applies an anteromedial force toward the glenoid fossa [16]. McFarland et al recently proposed a modified technique to improve control of the scapula and ability to feel the humeral head subluxate over the glenoid rim. With the patient’s shoulder abducted 60° to 70°, the examiner’s hands grasp the humerus and the patient’s wrist – instead of the scapula and humerus – and applies an anteromedial force throughout the arm (Figure 1) [17].
