This study investigated the biomechanical performance of decellularized porcine superflexor tendon (pSFT) grafts of varying diameters when utilized in conjunction with contemporary ACL graft fixation systems. This aimed to produce a range of ‘off-the-shelf’ products with predictable mechanical performance, depending on the individual requirements of the patient. Decellularized pSFTs were prepared to create double-bundle grafts of 7 mm, 8 mm, and 9 mm diameter. Femoral and tibial fixation systems were simulated utilizing Arthrex suspension devices and interference screws in bovine bone, respectively. Dynamic stiffness and creep were measured, followed by ramp to failure from which linear stiffness and load at failure were measured. The mechanisms of failure were also recorded.Objectives

Re-rupture is common after primary flexor tendon repair. Characterization of the biological changes in the ruptured tendon stumps would be helpful, not only to understand the biological responses to the failed tendon repair, but also to investigate if the tendon stumps could be used as a recycling biomaterial for tendon regeneration in the secondary grafting surgery. A canine flexor tendon repair and failure model was used. Following six weeks of repair failure, the tendon stumps were analyzed and characterized as isolated tendon-derived stem cells (TDSCs).Objectives
Methods
Although gradual bone transport may permit the
restoration of large-diameter bones, complications are common owing
to the long duration of external fixation. In order to reduce such
complications, a new technique of bone transport involving the use
of an external fixator and a locking plate was devised for segmental
tibial bone defects. A total of ten patients (nine men, one woman) with a mean age
at operation of 40.4 years (16 to 64) underwent distraction osteogenesis
with a locking plate to treat previously infected post-traumatic
segmental tibial defects. The locking plate was fixed percutaneously
to bridge proximal and distal segments, and was followed by external fixation.
After docking, percutaneous screws were fixed at the transported
segment through plate holes. At the same time, bone grafting was
performed at the docking site with the external fixator removed. The mean defect size was 5.9 cm (3.8 to 9.3) and mean external
fixation index was
13.4 days/cm (11.8 to 19.5). In all cases, primary union of the
docking site and distraction callus was achieved, with an excellent
bony result. There was no recurrence of deep infection or osteomyelitis,
and with the exception of one patient with a pre-existing peroneal

Low haemoglobin (Hb) at admission has been identified as a risk factor for mortality for elderly patients with hip fractures in some studies. However, this remains controversial. This study aims to analyze the association between Hb level at admission and mortality in elderly patients with hip fracture undergoing surgery. All consecutive patients (prospective database) admitted with hip fracture operated in a tertiary hospital between 2012 and 2016 were analyzed. We collected patient characteristics, time to surgery, duration and type of surgery, comorbidities, Hb at admission, nadir of Hb after surgery, the use and amount of red blood cells (RBCs) transfusion products, postoperative complications, and death. The main outcome measures were mortality at 30 days, 90 days, 180 days, and one year after surgery.Aims
Patients and Methods
We describe the routine imaging practices of
Level 1 trauma centres for patients with severe pelvic ring fractures, and
the interobserver reliability of the classification systems of these
fractures using plain radiographs and three-dimensional (3D) CT
reconstructions. Clinical and imaging data for 187 adult patients
(139 men and 48 women, mean age 43 years (15 to 101)) with a severe
pelvic ring fracture managed at two Level 1 trauma centres between July
2007 and June 2010 were extracted. Three experienced orthopaedic
surgeons classified the plain radiographs and 3D CT reconstruction
images of 100 patients using the Tile/AO and Young–Burgess systems.
Reliability was compared using kappa statistics. A total of
115 patients (62%) had plain radiographs as well as two-dimensional
(2D) CT and 3D CT reconstructions, 52 patients (28%) had plain films
only, 12 (6.4%) had 2D and 3D CT reconstructions images only, and
eight patients (4.3%) had no available images. The plain radiograph
was limited to an anteroposterior pelvic view. Patients without
imaging, or only plain films, were more severely injured. A total
of 72 patients (39%) were imaged with a pelvic binder in
situ. Interobserver reliability for the Tile/AO (Kappa 0.10 to 0.17)
and Young–Burgess (Kappa 0.09 to 0.21) was low, and insufficient
for clinical and research purposes. Severe pelvic ring fractures are difficult to classify due to
their complexity, the increasing use of early treatment such as
with pelvic binders, and the absence of imaging altogether in important
patient sub-groups, such as those who die early of their
Revision total hip replacement (THR) for young
patients is challenging because of technical complexity and the potential
need for subsequent further revisions. We have assessed the survivorship,
functional outcome and complications of this procedure in patients
aged <
50 years through a large longitudinal series with consistent treatment
algorithms. Of 132 consecutive patients (181 hips) who underwent
revision THR, 102 patients (151 hips) with a mean age of 43 years
(22 to 50) were reviewed at a mean follow-up of 11 years (2 to 26)
post-operatively. We attempted to restore bone stock with allograft
where indicated. Using further revision for any reason as an end point,
the survival of the acetabular component was 71% (. sd. 4)
and 54% (. sd. 7) at ten- and 20 years. The survival of the
femoral component was 80% (. sd. 4) and 62% (. sd. 6)
at ten- and 20 years. Complications included 11 dislocations (6.1%),
ten periprosthetic fractures (5.5%), two deep infections (1.1%),
four sciatic nerve palsies (2.2%; three resolved without intervention,
one improved after exploration and freeing from adhesions) and one

The aim of this randomized trial was to compare the functional outcome of two different surgical approaches to the hip in patients with a femoral neck fracture treated with a hemiarthroplasty. A total of 150 patients who were treated between February 2014 and July 2017 were included. Patients were allocated to undergo hemiarthroplasty using either an anterolateral or a direct lateral approach, and were followed for 12 months. The mean age of the patients was 81 years (69 to 90), and 109 were women (73%). Functional outcome measures, assessed by a physiotherapist blinded to allocation, and patient-reported outcome measures (PROMs) were collected postoperatively at three and 12 months.Aims
Patients and Methods
In adults with brachial plexus
McFarland fractures of the medial malleolus in
children, also classified as Salter–Harris Type III and IV fractures,
are associated with a high incidence of premature growth plate arrest.
In order to identify prognostic factors for the development of complications
we reviewed 20 children with a McFarland fracture that was treated
surgically, at a mean follow-up of 8.9 years (3.5 to 17.4). Seven
children (35%) developed premature growth arrest with angular deformity.
The mean American Orthopaedic Foot and Ankle Society Ankle-Hindfoot
Scale for all patients was 98.3 (87 to 100) and the mean modified
Weber protocol was 1.15 (0 to 5). There was a significant correlation
between initial displacement (p = 0.004) and operative delay (p
= 0.007) with premature growth arrest. Both risk factors act independently
and additively, such that all children with both risk factors developed
premature arrest whereas children with no risk factor did not. We
recommend that fractures of the medial malleolus in children should
be treated by anatomical reduction and screw fixation within one
day of
Matrix metalloproteinases (MMPs), responsible
for extracellular matrix remodelling and angiogenesis, might play
a major role in the response of the growth plate to detrimental
loads that lead to overuse
The purpose of this study was to determine the functional outcome and implant survivorship of mobile-bearing total ankle arthroplasty (TAA) performed by a single surgeon. We reviewed 205 consecutive patients (210 ankles) who had undergone mobile-bearing TAA (205 patients) for osteoarthritis of the ankle between January 2005 and December 2015. Their mean follow-up was 6.4 years (2.0 to 13.4). Functional outcome was assessed using the Ankle Osteoarthritis Scale, American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, 36-Item Short-Form Health Survey (SF-36) score, visual analogue scale, and range of movement. Implant survivorship and complications were also evaluated.Aims
