This study compared the quality of reduction
and complication rate when using a standard ilioinguinal approach and
the new pararectus approach when treating acetabular fractures surgically.
All acetabular fractures that underwent fixation using either approach
between February 2005 and September 2014 were retrospectively reviewed
and the demographics of the patients, the surgical details and complications
were recorded. A total of 100 patients (69 men, 31 women; mean age 57 years,
18 to 93) who were consecutively treated were included for analysis.
The quality of reduction was assessed using standardised measurement
of the gaps and steps in the articular surface on pre- and post-operative
CT-scans. There were no significant differences in the demographics of
the patients, the surgical details or the complications between
the two approaches. A significantly better reduction of the gap,
however, was achieved with the pararectus approach (axial: p = 0.025,
coronal: p = 0.013, sagittal: p = 0.001). These data suggest that the pararectus approach is at least equal
to, or in the case of reduction of the articular gap, superior to
the ilioinguinal approach. This approach allows direct buttressing of the dome of the acetabulum
and the quadrilateral plate, which is particularly favourable in
geriatric fracture patterns. Cite this article:
Our aim was to describe the mid-term appearances of the repair
process of the Achilles tendon after tenotomy in children with a
clubfoot treated using the Ponseti method. A total of 15 children (ten boys, five girls) with idiopathic
clubfoot were evaluated at a mean of 6.8 years (5.4 to 8.1) after
complete percutaneous division of the Achilles tendon. The contour
and subjective thickness of the tendon were recorded, and superficial
defects and its strength were assessed clinically. The echogenicity,
texture, thickness, peritendinous irregularities and potential for
deformation of the tendon were evaluated by ultrasonography.Aims

The optimal management of intracapsular fractures of the femoral
neck in independently mobile patients remains open to debate. Successful
fixation obviates the limitations of arthroplasty for this group
of patients. However, with fixation failure rates as high as 30%,
the outcome of revision surgery to salvage total hip arthroplasty
(THA) must be considered. We carried out a systematic review to
compare the outcomes of salvage THA and primary THA for intracapsular
fractures of the femoral neck. We performed a Preferred Reporting Items for Systematic Reviews
and Meta-Analysis (PRISMA) compliant systematic review, using the
PubMed, EMBASE and Cochrane libraries databases. A meta-analysis
was performed where possible, and a narrative synthesis when a meta-analysis
was not possible.Aims
Patients and Methods
We investigated the effects on fracture healing of two up-regulators of inducible nitric oxide synthase (iNOS) in a rat model of an open femoral osteotomy: tadalafil, a phosphodiesterase inhibitor, and the recently reported nutraceutical, COMB-4 (consisting of L-citrulline, Paullinia cupana, ginger and muira puama), given orally for either 14 or 42 days. Unilateral femoral osteotomies were created in 58 male rats and fixed with an intramedullary compression nail. Rats were treated daily either with vehicle, tadalafil or COMB-4. Biomechanical testing of the healed fracture was performed on day 42. The volume, mineral content and bone density of the callus were measured by quantitative CT on days 14 and 42. Expression of iNOS was measured by immunohistochemistry.Objectives

Extendible endoprostheses have been available for more than 30
years and have become more sophisticated with time. The latest generation
is ‘non-invasive’ and can be lengthened with an external magnetic
force. Early results have shown a worryingly high rate of complications
such as infection. This study investigates the incidence of complications
and the need for further surgery in a cohort of patients with a
non-invasive growing endoprosthesis. Between 2003 and June 2014, 50 children (51 prostheses) had a
non-invasive growing prosthesis implanted for a primary bone sarcoma.
The minimum follow-up was 24 months for those who survived. Their
mean age was 10.4 years (6 to 14). The incidence of complications
and further surgery was documented.Aims

Femoral impaction bone grafting was first developed in 1987 using
morselised cancellous bone graft impacted into the femoral canal
in combination with a cemented, tapered, polished stem. We describe
the evolution of this technique and instrumentation since that time. Between 1987 and 2005, 705 revision total hip arthroplasties
(56 bilateral) were performed with femoral impaction grafting using
a cemented femoral stem. All surviving patients were prospectively
followed for a mean of 14.7 years (9.8 to 28.3) with no loss to
follow-up. By the time of the final review, 404 patients had died.Aims

The aim of this to study was to compare the previously unreported
long-term survival outcome of the Oxford medial unicompartmental
knee arthroplasty (UKA) performed by trainee surgeons and consultants. We therefore identified a previously unreported cohort of 1084
knees in 947 patients who had a UKA inserted for anteromedial knee
arthritis by consultants and surgeons in training, at a tertiary
arthroplasty centre and performed survival analysis on the group
with revision as the endpoint.Aims

Haematomas, drainage, and other non-infectious
wound complications following total knee replacement (TKR) have
been associated with long-term sequelae, in particular, deep infection.
However, the impact of these wound complications on clinical outcome
is unknown. This study compares results in 15 patients re-admitted
for wound complications within 90 days of TKR to 30 matched patients
who underwent uncomplicated total knee replacements. Patients with
wound complications had a mean age of 66 years (49 to 83) and mean
body mass index (BMI) of 37 (21 to 54), both similar to that of
patients without complications (mean age 65 years and mean BMI 35). Those
with complications had lower mean Knee Society function scores (46

This non-blinded randomised controlled trial compared the effect
of patient-controlled epidural analgesia (PCEA) A total of 242 patients were randomised; 20 were excluded due
to failure of spinal anaesthesia leaving 109 patients in the PCEA

We present a review of litigation claims relating
to foot and ankle surgery in the NHS in England during the 17-year period
between 1995 and 2012. A freedom of information request was made to obtain data from
the NHS litigation authority (NHSLA) relating to orthopaedic claims,
and the foot and ankle claims were reviewed. During this period of time, a total of 10 273 orthopaedic claims
were made, of which 1294 (12.6%) were related to the foot and ankle.
1036 were closed, which comprised of 1104 specific complaints. Analysis
was performed using the complaints as the denominator. The cost
of settling these claims was more than £36 million. There were 372 complaints (33.7%) involving the ankle, of which
273 (73.4%) were related to trauma. Conditions affecting the first
ray accounted for 236 (21.4%), of which 232 (98.3%) concerned elective
practice. Overall, claims due to diagnostic errors accounted for
210 (19.0%) complaints, 208 (18.8%) from alleged incompetent surgery
and 149 (13.5%) from alleged mismanagement. Our findings show that the incorrect, delayed or missed diagnosis
of conditions affecting the foot and ankle is a key area for improvement,
especially in trauma practice. Cite this article:
Resection of malignant bony tumours of the pelvis
creates large bone and soft-tissue defects, and is frequently associated
with complications such as wound dehiscence and deep infection.
We present the results of six patients in whom a rectus abdominis
myocutaneous (RAM) flap was used following resection of a malignant
tumour of the pelvis. Bony reconstruction was performed using a
constrained hip tumour prosthesis in three patients, vascularised
fibular graft in two and frozen autograft in one. At a mean follow-up
of 63 months (16 to 115), no patients had a problem with the wound. Immediate reconstruction using a RAM flap may be used after resection
of a malignant tumour of the pelvis to provide an adequate volume
of tissue to eliminate the dead space, cover the exposed bone or
implants with well-vascularised soft tissue and to reduce the risk
of complications. Cite this article:
This article presents a unified clinical theory
that links established facts about the physiology of bone and homeostasis,
with those involved in the healing of fractures and the development
of nonunion. The key to this theory is the concept that the tissue
that forms in and around a fracture should be considered a specific
functional entity. This ‘bone-healing unit’ produces a physiological
response to its biological and mechanical environment, which leads
to the normal healing of bone. This tissue responds to mechanical
forces and functions according to Wolff’s law, Perren’s strain theory
and Frost’s concept of the “mechanostat”. In response to the local
mechanical environment, the bone-healing unit normally changes with
time, producing different tissues that can tolerate various levels
of strain. The normal result is the formation of bone that bridges
the fracture – healing by callus. Nonunion occurs when the bone-healing
unit fails either due to mechanical or biological problems or a
combination of both. In clinical practice, the majority of nonunions
are due to mechanical problems with instability, resulting in too
much strain at the fracture site. In most nonunions, there is an
intact bone-healing unit. We suggest that this maintains its biological
potential to heal, but fails to function due to the mechanical conditions.
The theory predicts the healing pattern of multifragmentary fractures
and the observed morphological characteristics of different nonunions.
It suggests that the majority of nonunions will heal if the correct
mechanical environment is produced by surgery, without the need
for biological adjuncts such as autologous bone graft. Cite this article:
Depression can significantly affect quality of life and is associated
with higher rates of medical comorbidities and increased mortality
following surgery. Although depression has been linked to poorer
outcomes following orthopaedic trauma, total joint arthroplasty
and spinal surgery, we wished to examine the impact of depression
in elective total shoulder arthroplasty (TSA) as this has not been
previously explored. The United States Nationwide Inpatient Sample (NIS) was used
to identify patients undergoing elective TSA over a ten-year period.
Between 2002 and 2012, 224 060 patients underwent elective TSA.Aims

The objective of this study was to determine if the use of fascia lata as a tendon regeneration guide (placed into the tendon canal following harvesting the semitendinosus tendon) would improve the incidence of tissue regeneration and prevent fatty degeneration of the semitendinosus muscle. Bilateral semitendinosus tendons were harvested from rabbits using a tendon stripper. On the inducing graft (IG) side, the tendon canal and semitendinosus tibial attachment site were connected by the fascia lata, which was harvested at the same width as the semitendinosus tendon. On the control side, no special procedures were performed. Two groups of six rabbits were killed at post-operative weeks 4 and 8, respectively. In addition, three healthy rabbits were killed to obtain normal tissue. We evaluated the incidence of tendon tissue regeneration, cross-sectional area of the regenerated tendon tissue and proportion of fatty tissue in the semitendinosus muscle.Objectives

We performed a case–control study to compare
the rates of further surgery, revision and complications, operating time
and survival in patients who were treated with either an uncemented
hydroxyapatite-coated Corail bipolar femoral stem or a cemented
Exeter stem for a displaced intracapsular fracture of the hip. The
mean age of the patients in the uncemented group was 82.5 years
(53 to 97) and in the cemented group was 82.7 years (51 to 99) We used
propensity score matching, adjusting for age, gender and the presence
or absence of dementia and comorbidities, to produce a matched cohort
receiving an Exeter stem (n = 69) with which to compare the outcome of
patients receiving a Corail stem (n = 69). The Corail had a significantly
lower all-cause rate of further surgery (p = 0.016; odds ratio (OR)
0.18, 95% CI 0.04 to 0.84) and number of hips undergoing major further
surgery (p = 0.029; OR 0.13, 95% CI 0.01 to 1.09). The mean operating
time was significantly less for the Corail group than for the cemented Exeter
group (59 min [12 to 136] Cite this article:
