Nerve palsy is a well-described complication
following total hip arthroplasty, but is highly distressing and
disabling. A nerve palsy may cause difficulty with the post-operative
rehabilitation, and overall mobility of the patient. Nerve palsy
may result from compression and tension to the affected nerve(s)
during the course of the operation via surgical manipulation and
retractor placement, tension from limb lengthening or compression
from post-operative hematoma. In the literature, hip dysplasia,
lengthening of the leg, the use of an uncemented femoral component, and
female gender are associated with a greater risk of nerve palsy.
We examined our experience at a high-volume, tertiary care referral
centre, and found an overall incidence of 0.3% out of 39 056 primary

As adverse events related to metal on metal hip
arthroplasty have been better understood, there has been increased
interest in toxicity related to the high circulating levels of cobalt ions.
However, distinguishing true toxicity from benign elevations in
cobalt levels can be challenging. The purpose of this review is
to examine the use of cobalt alloys in total hip arthroplasty, to
review the methods of measuring circulating cobalt levels, to define
a level of cobalt which is considered pathological and to review
the pathophysiology, risk factors and treatment of cobalt toxicity.
To the best of our knowledge, there are 18 published cases where
cobalt metal ion toxicity has been attributed to the use of cobalt-chromium
alloys in hip arthroplasty. Of these cases, the great majority reported
systemic toxic reactions at serum cobalt levels more than 100 μg/L.
This review highlights some of the clinical features of cobalt toxicity,
with the goal that early awareness may decrease the risk factors
for the development of cobalt toxicity and/or reduce its severity. Take home message: Severe adverse events can arise from the release
of cobalt from metal-on-metal
Objectives. The primary aim of this study was to assess the reproducibility of the recalled preoperative Oxford Hip Score (OHS) and Oxford Knee Score (OKS) one year following
Aims. The aims of this study were to evaluate the clinical and radiological
outcomes of the Universal-2 total wrist arthroplasty (TWA) in patients
with rheumatoid arthritis. Patients and Methods. This was a retrospective review of all 95 Universal-2 TWAs which
were performed in our institution between 2003 to 2012 in patients
with rheumatoid arthritis. A total of six patients were lost to
follow-up and two died of unrelated causes. A total of ten patients
had bilateral procedures. Accordingly, 75 patients (85 TWAs) were
included in the study. There were 59 women and 16 men with a mean
age of 59 years (26 to 86). The mean follow-up was 53 months (24
to 120). Clinical assessment involved recording pain on a visual
analogue score, range of movement, grip strength, the Quick Disabilities
of the Arm, Shoulder and Hand (DASH) and Wrightington wrist scores.
Any adverse effects were documented with particular emphasis on
residual pain, limitation of movement, infection, dislocation and
the need for revision surgery. Radiographic assessment was performed pre-operatively and at
three, six and 12 months post-operatively, and annually thereafter.
Arthroplasties were assessed for distal row intercarpal fusion and
loosening. Radiolucent zones around the components were documented
according to a system developed at our institution. Results. The mean worst pain was 8.1 (3 to 10) pre-operatively and 5.4
(0 to 10) at latest follow-up (p <
0.001). Movements were preserved
with mean dorsiflexion of 29. o . (0. o. to 70. o. )
and palmar flexion of 21. o. (0. o. to 50. o. ).
The mean grip strength was 4.8 kg (1.7 to 11.5) pre-operatively
and 10 kg (0 to 28) at final follow-up (p <
0.001). The mean
QuickDASH and Wrightington wrist scores improved from 61 (16 to
91) to 46 (0 to 89) and 7.9 (1.8 to 10) to 5.7 (0 to 7.8) (p <
0.001).

Aims. For this retrospective cohort study, patients aged ≤ 30 years
(very young) who underwent total hip arthroplasty (THA) were compared
with patients aged ≥ 60 years (elderly) to evaluate the rate of
