The aim of this study was to evaluate the accuracy of implant placement when using robotic assistance during total hip arthroplasty (THA). A total of 20 patients underwent a planned THA using preoperative CT scans and robotic-assisted software. There were nine men and 11 women (n = 20 hips) with a mean age of 60.8 years (Aims
Patients and Methods
We reviewed 508 consecutive total hip replacements in 370 patients with old developmental dysplasia of the hip, to relate the amount of leg lengthening to the incidence of nerve palsies after operation. There were eight nerve palsies (two femoral, six sciatic), two complete and six incomplete. We found no statistical correlation between the amount of lengthening and the incidence of nerve damage (p = 0.47), but in seven of the eight
The mucopolysaccharidoses (MPS) are a group of
inherited lysosomal storage disorders with clinical manifestations relevant
to the orthopaedic surgeon. Our aim was to review the recent advances
in their management and the implications for surgical practice. The current literature about MPSs is summarised, emphasising
orthopaedic complications and their management. Recent advances in the diagnosis and management of MPSs include
the recognition of slowly progressive, late presenting subtypes,
developments in life-prolonging systemic treatment and potentially
new indications for surgical treatment. The outcomes of surgery
in these patients are not yet validated and some procedures have
a high rate of complications which differ from those in patients
who do not have a MPS. The diagnosis of a MPS should be considered in adolescents or
young adults with a previously unrecognised dysplasia of the hip.
Surgeons treating patients with a MPS should report their experience
and studies should include the assessment of function and quality
of life to guide treatment. Cite this article:
To determine ten-year failure rates following 36 mm metal-on-metal
(MoM) Pinnacle total hip arthroplasty (THA), and identify predictors
of failure. We retrospectively assessed a single-centre cohort of 569 primary
36 mm MoM Pinnacle THAs (all Corail stems) followed up since 2012
according to Medicines and Healthcare Products Regulation Agency
recommendations. All-cause failure rates (all-cause revision, and
non-revised cross-sectional imaging failures) were calculated, with predictors
for failure identified using multivariable Cox regression.Aims
Patients and Methods
The aim of this study was to compare early functional and health
related quality of life outcomes (HRQoL) in patients who have undergone
total hip arthroplasty (THA) using a bone conserving short stem
femoral component and those in whom a conventional length uncemented
component was used. Outcome was assessed using a validated performance
based outcome instrument as well as patient reported outcome measures
(PROMs). We prospectively analysed 33 patients whose THA involved a contemporary
proximally porous coated tapered short stem femoral component and
53 patients with a standard conventional femoral component, at a
minimum follow-up of two years. The mean follow-up was 31.4 months
(24 to 39). Patients with poor proximal femoral bone quality were
excluded. The mean age of the patients was 66.6 years (59 to 77)
and the mean body mass index was 30.2 kg/m2 (24.1 to
41.0). Outcome was assessed using the Oxford Hip Score (OHS) and
the University College Hospital (UCH) hip score which is a validated
performance based instrument. HRQoL was assessed using the EuroQol
5D (EQ-5D).Aims

We present a minimum 20-year follow-up study of 382 cemented
Exeter Universal total hip arthroplasties (350 patients) operated
on at a mean age of 66.3 years (17 to 94). All patients received the same design of femoral component, regardless
of the original diagnosis. Previous surgery had been undertaken
for 33 hips (8.6%). During the study period 218 patients with 236
hips (62%) died, 42 hips (11%) were revised and 110 hips (29%) in
96 patients were available for review. The acetabular components
were varied and some designs are now obsolete, however they were
all cemented.Aims
Patients and Methods
The aim of this study was to evaluate the long-term clinical
and radiographic outcomes of the Birmingham Interlocking Pelvic
Osteotomy (BIPO). In this prospective study, we report the mid- to long-term clinical
outcomes of the first 100 consecutive patients (116 hips; 88 in
women, 28 in men) undergoing BIPO, reflecting the surgeon’s learning
curve. Failure was defined as conversion to hip arthroplasty. The
mean age at operation was 31 years (7 to 57). Three patients (three
hips) were lost to follow-up.Aims
Patients and Methods
A possible solution for the management of proximal femoral bone
loss is a modular femoral endoprosthesis (EPR). Although the outcome
of EPRs in tumour surgery has been well described, the outcome of
their use in revision hip surgery has received less attention. The
aim of this study was to describe the outcome of using EPR for non-neoplastic
indications. A retrospective review of 79 patients who underwent 80 EPRs for
non-neoplastic indications was performed, including the rates of
complication and survival and the mean Oxford Hip Scores (OHS),
at a mean of five years post-operatively. The mean age at the time
of surgery was 69 years (28 to 93) and the mean number of previous operations
on the hip was 2.4 (0 to 17). The most common indications for EPR
implantation were periprosthetic joint infection (PJI) (n = 40),
periprosthetic fracture (n = 12) and failed osteosynthesis of a
proximal femoral fracture or complex trauma (n = 11).Objectives
