Shoulder Arthrodesis

Shoulder arthrodesis with a reconstruction plate

“…However, Barton asserted that a direct correlation does not exist between a fixed angle of the shoulder joint and pain of the muscles supporting the shoulder, and that excessive abduction and internal rotation should be avoided, but some variation in the position of arthrodesis appears to be permissible [2]. The optimal position for shoulder joint fixation remains controversial; however, many researchers agree that some degree of abduction and flexion and a greater internal rotation are necessary [5]. In our study, the shoulder was fixed in a standard position at which the hand could reach the mouth and groin; this position was mainly 15°abduction, 15°f lexion and 40°internal rotation.…”

“…Further, the former reduces skin irritation since there are relatively few protrusions of the implant [15]. Clare et al recommended the use of a reconstruction plate in routine cases, but preferred the use of a DCP in obese patients weighing more than 100 kg [5] (Table 3).…”

“…After tumour resection, shoulder arthrodesis can be a more appropriate alternative than amputation from the viewpoint of aesthetics and function in cases where arthroplasty is not feasible due to the bone deficit in the proximal humerus and severely damaged surrounding soft tissue [4,5,22]. Cheng and Gebhardt reported a high patient satisfaction rate in all patients undergoing shoulder arthrodesis after malignant bone tumour resection.…”

Arthroscopic Glenohumeral Arthrodesis With O-Arm Navigation

“…The shoulder is held in a position of 30 of flexion, 20 of abduction, and 40 of internal rotation to mimic the previous position of the arm and the desired position for glenohumeral arthrodesis. 1 With the arm held in the appropriate position, 3 to 4 guidewires for 6.5-mm cannulated screws are percutaneously inserted from the humeral head into the glenoid and from the acromion to the humeral head 8 with the guidance of intraoperative computer-assisted navigation (Fig 4) and under direct arthroscopic visualization. Anatomic landmarks are used to avoid injury to the neurovascular structures, particularly the axillary nerve laterally.…”

“…Traditionally, the procedure has been performed in an open manner with screw and/or plate fixation. [1][2][3] Arthroscopic glenohumeral arthrodesis has been described in a few cases. [4][5][6][7] An arthroscopic approach to arthrodesis allows complete visualization so that accurate acromiohumeral and glenohumeral decortication can be performed while minimizing invasiveness.…”
