“…Although the glenohumeral joint capsule may be thickened on MRI in adhesive capsulitis, findings of amyloidosis in the shoulder may be differentiated by thickening of the substance of the rotator cuff, infiltration of fibrous tissue, and eventual rupture of the rotator cuff. Ando et al 29 proposed an MRI-based classification system for hemodialysis-related amyloidosis of the shoulder (Table 1). The diagnosis of amyloidosis is established histologically.…”

“…At a mean of 29.8 months follow-up, satisfactory pain relief was seen in 34 of 36 shoulders, with the mean Japanese Orthopaedic Surgery Association shoulder score improving from 66.4 preoperatively to 86.6 postoperatively. 30 Ando et al 29 suggested that grade 1 and 2 cases may benefit from arthroscopic synovectomy and débridement, whereas complete resections may be technically difficult in grade 3 cases. Outcomes of arthroscopic synovectomy and débridement in Ando et al grade 4 cases have not been reported, and these cases may benefit from open synovectomy and débridement and reverse total shoulder arthroplasty.…”

Amyloidosis is a disorder of misfolded proteins in human tissues, which can result in morbid cardiac and neurological disease. Historically, the utility of tissue biopsy during orthopaedic procedures to detect amyloidosis has been limited because no disease-modifying therapies were available; however, new drug therapies have recently emerged for the treatment of amyloidosis. Although these novel pharmaceuticals show promise for slowing disease progression, they are primarily effective in the early stages of amyloidosis, underscoring the importance of early diagnosis. Common orthopaedic manifestations of amyloidosis include carpal tunnel syndrome, trigger finger, spontaneous distal biceps tendon rupture, rotator cuff disease, and lumbar spinal stenosis. Carpal tunnel syndrome is frequently the earliest manifestation of amyloidosis, on average preceding a formal diagnosis of amyloidosis by over four years. By recognizing the constellation of musculoskeletal symptoms in the patient with amyloidosis, orthopaedic surgeons can play an active role in patient referral, early detection of systemic disease, and prompt initiation of disease-modifying treatment. There may be a role for selective biopsy for amyloid deposition in at-risk patients during routine orthopaedic procedures.

“…Several measurement methods have been developed to quantify the amount of humeral bone loss [17,18,23,37,39,49]. However, the accuracy and reproducibility of these methods when using diferent imaging modalities have been underinvestigated, and no consensus has been established to date [4,41,46].…”

PurposeThe aim of the current study was to compare the diagnostic precision and reliability of different methods in measuring Hill–Sachs lesions (HSLs) using MRI and CT. MethodsA total of 80 consecutive patients with a history of anterior shoulder instability were retrospectively included. The preoperative CT and MRI scans of the affected shoulders were analysed. To investigate the ability of the Franceschi grading, Calandra classification, Richards, Hall, and Rowe grading scale, Flatow percentage and “glenoid track” assessment according to Di Giacomo et al. to quantify the extent of humeral bone loss, the results of each measurement method obtained with MRI were compared with those achieved with CT. In addition, the intra‐ and inter‐rater reliabilities of each measurement method using CT and MRI were calculated and compared. ResultsA significant difference was found between CT and MRI in the determination of the Hill–Sachs interval (HSI) (p = 0.016), but not between the results of any of the other measurement techniques. With the exceptions of the Franceschi grade and Calandra classification, all measurement methods showed good or excellent intra‐ and inter‐rater reliabilities for both MRI and CT. ConclusionsWhile the determination of the HSI with MRI was more accurate, all other analysed techniques for measuring the amount of humeral bone loss showed similar diagnostic precision. With regard to the intra‐ and inter‐rater reliabilities, all measurement techniques analysed, with the exception of the Franceschi and Calandra classifications, provided good to very good reliabilities with both CT and MRI.
