Anterior/Volar (Henry’s) Approach to the Forearm
Raymond Anakwe, Scott Middleton in Trauma Vivas for the FRCS (Tr & Orth), 2017
I would extend the incision down through fat, taking care not to damage the cephalic vein, then identify the deep fascia. I would incise the deep fascia of the forearm in line with the skin incision. I would then identify the ulnar border of brachioradialis and develop the plane between it and flexor carpi radialis (FCR) distally and pronator teres proximally. Brachioradialis is the retracted laterally and pronator teres/FCR is taken medially. It may be necessary to ligate/coagulate the leash of Henry (recurrent branches of the radial artery) to mobilise the brachioradialis laterally and the radial artery medially. The superficial radial nerve runs on the underside of brachioradialis and is retracted laterally with the muscle.
Distal forearm
Sebastian Dawson-Bowling, Pramod Achan, Timothy Briggs, Manoj Ramachandran, Stephen Key, Daud Chou in Orthopaedic Trauma, 2014
A linear incision is made over the flexor carpi radialis tendon. The tendon may be retracted either radially or ulnarly. Dissection continues through the bed of the flexor carpi radialis tendon sheath, by developing the plane deep to this. Pronator quadratus is detached from its radial border and is reflected toward the ulna. Brachioradialis has a broad insertion onto the radial styloid and acts as a deforming force that may prevent accurate reduction. Complete release of brachioradialis will aid in these instances. Structures at risk are the median nerve and radial neurovascular bundle, which should be identified and protected throughout the procedure.
The Antebrachium
Gene L. Colborn, David B. Lause in Musculoskeletal Anatomy, 2009
Lateral to the tendon of the biceps, situated deeply between the brachioradialis and brachialis muscles, the radial nerve should be identified as it enters the forearm. It pierces the lateral intermuscular septum to pass from the extensor compartment into the flexor compartment. The superficial radial nerve remains deep to the brachioradialis as they pass together toward the hand. Several inches proximal to the wrist joint the superficial radial nerve emerges from beneath the tendon of the brachioradialis to begin its distribution of cutaneous branches to the radial aspect of the dorsum of the hand.

In the anatomical point of view, the elbow joint's flexion consists not only of biceps short and long head, but also by brachioradialis, brachialis, and pronator teres. In upper limb spasticity, it is ubiquitous that all of these three muscles are affected (Gharbaoui et al. 2016). Brachioradialis muscle has been shown to be the most spastic of these flexors (Keenan et al. 1990). Total isolation of biceps during evaluation is difficult, and recruitment of other muscles involvement cannot be avoided (Gharbaoui et al. 2016). Hence, sEMG recording on biceps alone might not give true value of spasticity leads to incorrect prediction (Keenan et al. 1990; Gharbaoui et al. 2016). However, this can be overcome by evaluating the reactive resistive magnitude, which gives more reliable value of spasticity, in which this resistance aids in providing subjective appreciation during traditional clinical examination (Kumar et al. 2006; Fleuren et al. 2010).

The preferred site for PA during thyroid surgery is the SCM,8–10,11–13,16–33 since it can be reached by the same approach used for thyroidectomy, it is highly vascularized and can provide an easy approach for the pocket made to receive the fragmented glands. So, the majority of papers dealing with PA reports the use of this muscle. In 3 papers14,34,35 the site for PA is not mentioned, while two authors19,36 reported the use of pectoralis muscle. The other 4 papers deal with reimplantation in peripheral sites, the brachioradialis muscle in two37,38 subcutaneous tissue of forearm in two.9,15 The last two papers, dealing with PA within subcutaneous tissue, deal with two different techniques. In one study15 the gland was fragmented as usual and then reimplanted in one or two pockets in the subcutaneous tissue, while in the other study9 described the injection technique, in which the gland was minced in saline solution and then directly injected within the subcutaneous tissue. Both series report good results, even if only in one of these15 the graft functionality has been clearly demonstrated.

The skin and subcutaneous adipose tissue were removed. The radial nerve was located in the intramuscular space of the brachialis and brachioradialis at the middle and distal segment of the humerus. To fully expose the radial nerve along the length of the upper arm, we excised it at the proximal end through the lateral muscle gap, and then split the triceps muscle and separated the radial nerve in the muscle compartment toward the distal end. Care was taken to avoid excessive dissection of adherent tissues surrounding the radial nerve, so as not to disturb the anatomical relationship between the radial nerve and the humerus. Next, an elastic guide wire (Certofix central venous catheter; B. Braun, Germany) with a diameter of 0.89 mm was fixed by suturing along the radial nerve. The dissected tissues were replaced carefully after the guide wire had been fixed (Figure 1).
