We investigated whether strontium-enriched calcium
phosphate cement (Sr-CPC)-treated soft-tissue tendon graft results
in accelerated healing within the bone tunnel in reconstruction
of the anterior cruciate ligament (ACL). A total of 30 single-bundle

The treatment of infected nonunions is difficult.
Antibiotic cement-coated (ACC) rods provide stability as well as delivering
antibiotics. We conducted a review of 110 infected nonunions treated
with ACC rods. Patients were divided into two groups: group A (67
patients) with an infected arthrodesis, and group B (43 patients)
with an infected nonunion in a long bone. In group A, infected arthrodesis,
the success rate after the first procedure was 38/67 (57%), 29/67
(43%) required further surgery for either control of infection or
non-union. At last follow-up, five patients required amputation,

The aim of this study was to establish a reliable method for producing 3D reconstruction of sonographic callus. A cohort of ten closed tibial shaft fractures managed with intramedullary nailing underwent ultrasound scanning at two, six, and 12 weeks post-surgery. Ultrasound capture was performed using infrared tracking technology to map each image to a 3D lattice. Using echo intensity, semi-automated mapping was performed to produce an anatomical 3D representation of the fracture site. Two reviewers independently performed 3D reconstructions and kappa coefficient was used to determine agreement. A further validation study was undertaken with ten reviewers to estimate the clinical application of this imaging technique using the intraclass correlation coefficient (ICC).Aims

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)

This is a case series of prospectively gathered
data characterising the injuries, surgical treatment and outcomes
of consecutive British service personnel who underwent a unilateral
lower limb amputation following combat injury. Patients with primary,
unilateral loss of the lower limb sustained between March 2004 and
March 2010 were identified from the United Kingdom Military Trauma
Registry. Patients were asked to complete a Short-Form (SF)-36 questionnaire.
A total of 48 patients were identified: 21 had a trans-tibial amputation,
nine had a knee disarticulation and 18 had an amputation at the
trans-femoral level. The median New Injury Severity Score was 24 (mean
27.4 (9 to 75)) and the median number of procedures per residual
limb was 4 (mean 5 (2 to 11)). Minimum two-year SF-36 scores were
completed by 39 patients (81%) at a mean follow-up of 40 months
(25 to 75). The physical component of the SF-36 varied significantly
between different levels of amputation (p = 0.01). Mental component
scores did not vary between amputation levels (p = 0.114). Pain
(p = 0.332), use of prosthesis (p = 0.503), rate of re-admission
(p = 0.228) and mobility (p = 0.087) did not vary between amputation
levels. These findings illustrate the significant impact of these injuries
and the considerable surgical burden associated with their treatment.

The use of 3D printing has become increasingly popular and has been widely used in orthopaedic surgery. There has been a trend towards an increasing number of publications in this field, but existing literature incorporates limited high-quality studies, and there is a lack of reports on outcomes. The aim of this study was to perform a scoping review with Level I evidence on the application and effectiveness of 3D printing. A literature search was performed in PubMed, Embase, and Web of Science databases. The keywords used for the search criteria were ((3d print*) OR (rapid prototyp*) OR (additive manufactur*)) AND (orthopaedic). The inclusion criteria were: 1) use of 3D printing in orthopaedics, 2) randomized controlled trials, and 3) studies with participants/patients. Risk of bias was assessed with Cochrane Collaboration Tool and PEDro Score. Pooled analysis was performed.Aims
Methods
Surgical treatment of young femoral neck fractures often requires an open approach to achieve an anatomical reduction. The application of a calcar plate has recently been described to aid in femoral neck fracture reduction and to augment fixation. However, application of a plate may potentially compromise the regional vascularity of the femoral head and neck. The purpose of this study was to investigate the effect of calcar femoral neck plating on the vascularity of the femoral head and neck. A Hueter approach and capsulotomy were performed bilaterally in six cadaveric hips. In the experimental group, a one-third tubular plate was secured to the inferomedial femoral neck at 6:00 on the clockface. The contralateral hip served as a control with surgical approach and capsulotomy without fixation. Pre- and post-contrast MRI was then performed to quantify signal intensity in the femoral head and neck. Qualitative assessment of the terminal arterial branches to the femoral head, specifically the inferior retinacular artery (IRA), was also performed.Aims

The aims of this study were to develop an in vivo model of periprosthetic joint infection (PJI) in cemented hip hemiarthroplasty, and to monitor infection and biofilm formation in real-time. Sprague-Dawley rats underwent cemented hip hemiarthroplasty via the posterior approach with pre- and postoperative gait assessments. Infection with Aims

This study aims to enhance understanding of clinical and radiological consequences and involved mechanisms that led to corrosion of the Precice Stryde (Stryde) intramedullary lengthening nail in the post market surveillance era of the device. Between 2018 and 2021 more than 2,000 Stryde nails have been implanted worldwide. However, the outcome of treatment with the Stryde system is insufficiently reported. This is a retrospective single-centre study analyzing outcome of 57 consecutive lengthening procedures performed with the Stryde nail at the authors’ institution from February 2019 until November 2020. Macro- and microscopic metallographic analysis of four retrieved nails was conducted. To investigate observed corrosion at telescoping junction, scanning electron microscopy (SEM) and energy dispersive x-ray spectroscopy (EDX) were performed.Aims

Aims. Following the resection of an extensive amount of bone in the
treatment of a tumour, the residual segment may be insufficient
to accept a standard length intramedullary cemented stem. Short-stemmed
endoprostheses conceivably have an increased risk of aseptic loosening.
Extra-cortical plates have been added to minimise this risk by supplementing
fixation. The aim of this study was to investigate the survivorship
of short-stemmed endoprostheses and extra-cortical plates. Patients and Methods. The study involved 37 patients who underwent
