Aims. Radiostereometric analysis (RSA) allows an extremely accurate
measurement of early micromotion of components following arthroplasty. . Patients and Methods. In this study, RSA was used to measure the migration of 11 partially
cemented fluted pegged glenoid components in patients with osteoarthritis
who underwent total shoulder arthroplasty using an improved surgical
technique (seven men, four women, mean age 68). Patients were evaluated
clinically using the American Shoulder and Elbow Surgeons (ASES)
and Constant-Murley scores and by CT scans two years post-operatively. . Results. There were two patterns of migration, the first showing little,
if any, migration and the second showing rotation by >
6° as early
as three months post-operatively. At two years, these two groups
could be confirmed on CT scans, one with osseointegration around
the central peg, and the second with
The Mathys Affinis Short is the most frequently used stemless total shoulder prosthesis in the UK. The purpose of this prospective cohort study is to report the survivorship, clinical, and radiological outcomes of the first independent series of the Affinis Short prosthesis. From January 2011 to January 2019, a total of 141 Affinis Short prostheses were implanted in 127 patients by a single surgeon. Mean age at time of surgery was 68 (44 to 89). Minimum one year and maximum eight year follow-up (mean 3.7 years) was analyzed using the Oxford Shoulder Score (OSS) at latest follow-up. Kaplan-Meier survivorship analysis was performed with implant revision as the endpoint. Most recently performed radiographs were reviewed for component radiolucent lines (RLLs) and proximal humeral migration.Aims
Methods
The Walch Type C dysplastic glenoid is characterized by excessive
retroversion. This anatomical study describes its morphology. A total of 29 shoulders with a dysplastic glenoid were analyzed.
CT was used to measure retroversion, inclination, height, width,
radius-of-curvature, surface area, depth, subluxation of the humeral
head and the Goutallier classification of fatty infiltration. The
severity of dysplasia and deficiency of the posterior rim of the
glenoid were recorded.Aims
Patients and Methods
We retrospectively evaluated the clinical and
radiological outcomes of a consecutive cohort of patients aged >
70 years with a displaced fracture of the olecranon, which was treated
non-operatively with early mobilisation. We identified 28 such patients
(27 women) with a mean age of 82 years (71 to 91). The elbow was
initially immobilised in an above elbow cast in 90° of flexion of
the elbow for a mean of five days. The cast was then replaced by
a sling. Active mobilisation was encouraged as tolerated. No formal
rehabilitation was undertaken. At a mean follow-up of 16 months
(12 to 26), the mean ranges of flexion and extension were 140° and
15° respectively. On a visual analogue scale of 1 (no pain) to 10,
the mean pain score was 1 (0 to 8). Of the original 28 patients
22 developed nonunion, but no patients required surgical treatment. We conclude that non-operative functional treatment of displaced
olecranon fractures in the elderly gives good results and a high
rate of satisfaction. Cite this article:
