Shoulder Arthrodesis in14 Dogs

Abstract

Shoulder arthrodesis in dogs results in acceptable limb function and should be considered for the management of debilitating shoulder pathology despite a high incidence of complications. Application of the SOP plate to aid shoulder arthrodesis warrants further study.

Bilateral shoulder arthrodesis in a Pekinese using three-dimensional printed patient-specific osteotomy and reduction guides

“…Additional significant reductions in operative time resulted from the guided osteotomy planes and the automatic, and maintained, reduction afforded by the reduction guide. The String-of-Pearls plate has been previously described for shoulder arthrodesis, but had the drawbacks of greater bulk than the locking compression plate / malleable locking plate in this small patient, and smaller core diameter of the locked screws (1).…”

“…Arthrodesis has been reported as a salvage technique for the management of a number of conditions affecting the shoulder including acute luxation, chronic instability, articular fracture, pain associated with osteoarthritis, dysplasia, osteochondromatosis, and proximal focal humeral deficiency (1)(2)(3)(4). Clinical outcomes have been described as good or excellent in over 85% of cases, although potentially catastrophic complications including infection and implant failure are reported (1,2,5,6).…”

Clinical outcomes have been described as good or excellent in over 85% of cases, although potentially catastrophic complications including infection and implant failure are reported (1,2,5,6). The risk of such adverse events may, at least in part, be increased by the specific challenges inherent to shoulder arthrodesis, including the relative paucity of proximal bone stock, the requirement for significant multiplanar plate contouring, and the difficulty of achieving optimal humerus-scapula alignment in all three planes.…”

Although the bio-mechanical advantages of locking implants and double plating are beneficial in this context, shoulder arthrodesis remains a technically challenging procedure (1).…”

Shoulder joint hemiarthroplasty for treatment of a severe osteochondritis dissecans lesion in a dog

“…However, proximity of the osteochondritis dissecans lesion to the caudal distal articular cartilage border may present challenges in achieving adequate stability of the grafted osteochondral cores, and the harvesting of large quantities of osteochondral material from a non-pathologic donor joint for osteochondral autograft transfer procedures remains a potential concern (8,9). Shoulder arthrodesis has been described in dogs as a salvage procedure for chronic osteoarthritis, chronic medial instability, comminuted glenoid fracture, traumatic luxation, biceps brachii tendinopathy and proximal humeral focal deficiency, but complications are not uncommon and some loss of function may be anticipated (10)(11)(12). Humeral head resurfacing using a hemiarthroplasty prosthesis in humans is well described and has been reported in an experimental canine model, but to the authors' knowledge has not been previously documented in clinical canine cases (13)(14)(15).…”
