This article is chiefly limited to the routine radiographic evaluation of shoulder arthroplasties and guidelines to their interpretation. Other imaging modalities for the evaluation of joint replacements are discussed elsewhere in this issue. The basic types of shoulder reconstructions and some of the shoulder replacement designs in previous and current use at The New York Orthopedic Hospital a...

In shoulder arthroplasty, malpositioning of prostheses often leads to reduced postoperative range of motion (ROM) and complications such as impingement, loosening, and dislocation. Furthermore, the risk of impingement complications increases when reverse total prostheses are used. For this purpose a pre-operative planning system was developed that enables surgeons to perform a virtual shoulder ...

We evaluate our experience with arthroscopic interpositioning arthroplasty as a treatment of the young degenerative shoulder joint. Between 2007 and 2009 ten patients were treated with either a dermal allograft or a meniscal allograft. In seven patients the graft failed and within 13 months these were revised to a total shoulder arthroplasty. Three patients are still satisfied after 7 to 8 year...

BACKGROUND. The objective of this study is to evaluate the response of the musculoskeletal system to enzyme replacement therapy in a group of patients with Mucopolysaccharidosis (MPS). MATERIAL AND METHODS. A retrospective study was done based on records from 22 patients with different types of MPS (I, II and VI) who were treated with enzyme replacement therapy (ERT). Patient data were evaluate...

BACKGROUND The Nordic Arthroplasty Register Association was initiated in 2007, and several papers about hip and knee arthroplasty have been published. Inspired by this, we aimed to examine the feasibility of merging data from the Nordic national shoulder arthroplasty registries by defining a common minimal data set. METHODS A group of surgeons met in 2014 to discuss the feasibility of merging...
