In the time since Letournel popularised the surgical
treatment of acetabular fractures, more than 25 years ago, there
have been many changes within the field, related to patients, surgical
technique, implants and post-operative care. However, the long-term
outcomes appear largely unchanged. Does this represent stasis or
have the advances been mitigated by other negative factors? In this
article we have attempted to document the recent changes within
the surgery of patients with a fracture involving the acetabulum,
outline contemporary management, and identify the major problem
areas where further research is most needed. Cite this article:
The August 2015 Children’s orthopaedics Roundup360 looks at: Learning the Pavlik; MRI and patellar instability; Cerebral palsy and hip dysplasia; ‘Pick your poison’: elastic nailing under the spotlight; Club feet and surgery; Donor site morbidity in vascularised fibular grafting; Cartilage biochemistry with hip dysplasia; SUFE and hip decompression: a good option?
In 1994 a cerebral palsy (CP) register and healthcare
programme was established in southern Sweden with the primary aim
of preventing dislocation of the hip in these children. The results from the first ten years were published in 2005 and
showed a decrease in the incidence of dislocation of the hip, from
8% in a historical control group of 103 children born between 1990
and 1991 to 0.5% in a group of 258 children born between 1992 and
1997. These two cohorts have now been re-evaluated and an additional
group of 431 children born between 1998 and 2007 has been added. By 1 January 2014, nine children in the control group, two in
the first study group and none in the second study group had developed
a dislocated hip (p <
0.001). The two children in the first study
group who developed a dislocated hip were too unwell to undergo
preventive surgery. Every child with a dislocated hip reported severe pain,
at least periodically, and four underwent salvage surgery. Of the
689 children in the study groups, 91 (13%) underwent preventive
surgery. A population-based hip surveillance programme enables the early
identification and preventive treatment, which can result in a significantly
lower incidence of dislocation of the hip in children with CP. Cite this article:
To investigate the bone penetration of intravenous antibiotic
prophylaxis with flucloxacillin and gentamicin during hip and knee
arthroplasty, and their efficacy against Bone samples from the femoral head, neck and acetabulum were
collected from 18 patients undergoing total hip arthroplasty (THA)
and from the femur and tibia in 21 patients during total knee arthroplasty
(TKA). The concentration of both antibiotics in the samples was
analysed using high performance liquid chromatography. Penetration
was expressed as a percentage of venous blood concentration. The
efficacy against common infecting organisms was measured against
both the minimum inhibitory concentration 50, and the more stringent epidemiological
cutoff value for resistance (ECOFF).Aims
Patients and Methods
We hypothesised that the use of computer navigation-assisted
surgery for pelvic and sacral tumours would reduce the risk of an
intralesional margin. We reviewed 31 patients (18 men and 13 women)
with a mean age of 52.9 years (13.5 to 77.2) in whom computer navigation-assisted
surgery had been carried out for a bone tumour of the pelvis or
sacrum. There were 23 primary malignant bone tumours, four metastatic
tumours and four locally advanced primary tumours of the rectum.
The registration error when using computer navigation was <
1 mm
in each case. There were no complications related to the navigation,
which allowed the preservation of sacral nerve roots (n = 13), resection
of otherwise inoperable disease (n = 4) and the avoidance of hindquarter
amputation (n = 3). The intralesional resection rate for primary
tumours of the pelvis and sacrum was 8.7% (n = 2): clear bone resection
margins were achieved in all cases. At a mean follow-up of 13.1
months (3 to 34) three patients (13%) had developed a local recurrence.
The mean time alive from diagnosis was 16.8 months (4 to 48). Computer navigation-assisted surgery is safe and has reduced
our intralesional resection rate for primary tumours of the pelvis
and sacrum. We recommend this technique as being worthy of further
consideration for this group of patients. Cite this article:
One method of femoral head preservation following avascular necrosis
(AVN) is core decompression and insertion of a tantalum rod. However,
there may be a high failure rate associated with this procedure.
The purpose of this study was to document the clinical and radiological
outcomes following total hip arthroplasty (THA) subsequent to failed
tantalum rod insertion. A total of 37 failed tantalum rods requiring total hip arthroplasty
were identified from a prospective database. There were 21 hips
in 21 patients (12 men and nine women, mean age 37 years, 18 to
53) meeting minimum two year clinical and radiographic follow-up
whose THAs were carried out between November 2002 and April 2013
(mean time between tantalum rod implantation and conversion to a
THA was 26 months, 6 to 72). These were matched by age and gender
to individuals (12 men, nine women, mean age 40 years, 18 to 58)
receiving THA for AVN without prior tantalum rod insertion.Aims
Patients and Methods
We compared the length of hospitalisation, rate
of infection, dislocation of the hip and revision, and mortality following
primary hip and knee arthroplasty for osteoarthritis in patients
with Alzheimer’s disease (n = 1064) and a matched control group
(n = 3192). The data were collected from nationwide Finnish health
registers. Patients with Alzheimer’s disease had a longer peri-operative
hospitalisation (median 13 days Cite this article:
There are several reports clarifying successful results following
open reduction using Ludloff’s medial approach for congenital (CDH)
or developmental dislocation of the hip (DDH). This study aimed
to reveal the long-term post-operative course until the period of
hip-joint maturity after the conventional surgical treatments. A long-term follow-up beyond the age of hip-joint maturity was
performed for 115 hips in 103 patients who underwent open reduction
using Ludloff’s medial approach in our hospital. The mean age at
surgery was 8.5 months (2 to 26) and the mean follow-up was 20.3
years (15 to 28). The radiological condition at full growth of the hip
joint was evaluated by Severin’s classification.Objectives
Methods
We investigated the incidence and risk factors
for the development of avascular necrosis (AVN) of the femoral head in
the course of treatment of children with cerebral palsy (CP) and
dislocation of the hip. All underwent open reduction, proximal femoral
and Dega pelvic osteotomy. The inclusion criteria were: a predominantly
spastic form of CP, dislocation of the hip (migration percentage,
MP >
80%), Gross Motor Function Classification System, (GMFCS) grade
IV to V, a primary surgical procedure and follow-up of >
one year. There were 81 consecutive children (40 girls and 41 boys) in
the study. Their mean age was nine years (3.5 to 13.8) and mean
follow-up was 5.5 years (1.6 to 15.1). Radiological evaluation included
measurement of the MP, the acetabular index (AI), the epiphyseal
shaft angle (ESA) and the pelvic femoral angle (PFA). The presence
and grade of AVN were assessed radiologically according to the Kruczynski
classification. Signs of AVN (grades I to V) were seen in 79 hips (68.7%). A
total of 23 hips (18%) were classified between grades III and V. Although open reduction of the hip combined with femoral and
Dega osteotomy is an effective form of treatment for children with
CP and dislocation of the hip, there were signs of avascular necrosis
in about two-thirds of the children. There was a strong correlation
between post-operative pain and the severity of the grade of AVN. Cite this article:
Reconstruction of the acetabulum after failed total hip arthroplasty
(THA) can be a surgical challenge in the presence of severe bone
loss. We report the long-term survival of a porous tantalum revision
acetabular component, its radiological appearance and quality of
life outcomes. We reviewed the results of 46 patients who had undergone revision
of a failed acetabular component with a Paprosky II or III bone
defect and reconstruction with a hemispherical, tantalum acetabular
component, supplementary screws and a cemented polyethylene liner.Aims
Patients and Methods
Hip arthroscopy in the setting of hip dysplasia is controversial in the orthopaedic community, as the outcome literature has been variable and inconclusive. We hypothesise that outcomes of hip arthroscopy may be diminished in the setting of hip dysplasia, but outcomes may be acceptable in milder or borderline cases of hip dysplasia. A systematic search was performed in duplicate for studies investigating the outcome of hip arthroscopy in the setting of hip dysplasia up to July 2015. Study parameters including sample size, definition of dysplasia, outcomes measures, and re-operation rates were obtained. Furthermore, the levels of evidence of studies were collected and quality assessment was performed.Objective
Methods
Using a systematic review, we investigated whether there is an
increased risk of post-operative infection in patients who have
received an intra-articular corticosteroid injection to the hip
for osteoarthritis prior to total hip arthroplasty (THA). Studies dealing with an intra-articular corticosteroid injection
to the hip and infection following subsequent THA were identified
from databases for the period between 1990 to 2013. Retrieved articles
were independently assessed for their methodological quality.Aims

The April 2014 Children’s orthopaedics Roundup360 looks at: urgent supracondylar fractures; rotational osteotomy for synostosis; predicting slip in paediatric forearm fractures; progressive lengthening of the digit is possible; treatment of SUFE with the Dunn osteotomy; and the best way to apply the eight-plate?.
This study investigated whether the use of tranexamic acid (TXA)
decreased blood loss and transfusion related cost following surface
replacement arthroplasty (SRA). A retrospective review of patients treated with TXA during a
SRA, who did not receive autologous blood (TXA group) was performed.
Two comparison groups were established; the first group comprised
of patients who donated their own blood pre-operatively (auto group)
and the second of patients who did not donate blood pre-operatively
(control). Outcomes included transfusions, post-operative haemoglobin
(Hgb), complications, and length of post-operative stay. Aims
