The ability to edit DNA at the nucleotide level using clustered regularly interspaced short palindromic repeats (CRISPR) systems is a relatively new investigative tool that is revolutionizing the analysis of many aspects of human health and disease, including orthopaedic disease. CRISPR, adapted for mammalian cell genome editing from a bacterial defence system, has been shown to be a flexible, programmable, scalable, and easy-to-use gene editing tool. Recent improvements increase the functionality of CRISPR through the engineering of specific elements of CRISPR systems, the discovery of new, naturally occurring CRISPR molecules, and modifications that take CRISPR beyond gene editing to the regulation of gene transcription and the manipulation of RNA. Here, the basics of CRISPR genome editing will be reviewed, including a description of how it has transformed some aspects of molecular
This Delphi study assessed the challenges of diagnosing soft-tissue knee injuries (STKIs) in acute settings among orthopaedic healthcare stakeholders. This modified e-Delphi study consisted of three rounds and involved 32 orthopaedic healthcare stakeholders, including physiotherapists, emergency nurse practitioners, sports medicine physicians, radiologists, orthopaedic registrars, and orthopaedic consultants. The perceived importance of diagnostic components relevant to STKIs included patient and external risk factors, clinical signs and symptoms, special clinical tests, and diagnostic imaging methods. Each round required scoring and ranking various items on a ten-point Likert scale. The items were refined as each round progressed. The study produced rankings of perceived importance across the various diagnostic components.Aims

Aims. We analyzed the long-term outcomes of patients observed over ten years after resection en bloc and reconstruction with extracorporeal irradiated autografts. Patients and Methods. This retrospective study included 27 patients who underwent resection en bloc and reimplantation of an extracorporeal irradiated autograft. The mean patient age and follow-up period were 31.7 years (9 to 59) and 16.6 years (10.3 to 24.3), respectively. The most common diagnosis was osteosarcoma (n = 10), followed by chondrosarcoma (n = 6). The femur (n = 13) was the most frequently involved site, followed by the tibia (n = 7). There were inlay grafts in five patients, intercalary grafts in 15 patients, and osteoarticular grafts in seven patients. Functional outcome was evaluated with the

of deep-vein thrombosis (DVT) after the resection of a musculoskeletal
tumour. A total of 94 patients who underwent resection of a musculoskeletal
tumour between January 2003 and December 2005 were prospectively
studied. There were 42 men and 52 women with a mean age of 54.4
years (18 to 86). All patients wore intermittent pneumatic compression
devices and graduated compression stockings. Ultrasound examination
of the lower limbs was conducted to screen for DVT between the fifth

Vertebrates have adapted to life on Earth and its constant gravitational field, which exerts load on the body and influences the structure and function of tissues. While the effects of microgravity on muscle and bone homeostasis are well described, with sarcopenia and osteoporosis observed in astronauts returning from space, the effects of shorter exposures to increased gravitational fields are less well characterized. We aimed to test how hypergravity affects early cartilage and skeletal development in a zebrafish model. We exposed zebrafish to 3 g and 6 g hypergravity from three to five days post-fertilization, when key events in jaw cartilage morphogenesis occur. Following this exposure, we performed immunostaining along with a range of histological stains and transmission electron microscopy (TEM) to examine cartilage morphology and structure, atomic force microscopy (AFM) and nanoindentation experiments to investigate the cartilage material properties, and finite element modelling to map the pattern of strain and stress in the skeletal rudiments.Aims

Patients and Methods
Local recurrence along the biopsy track is a
known complication of percutaneous needle biopsy of malignant musculoskeletal
tumours. In order to completely excise the track with the tumour
its identification is essential, but this becomes increasingly difficult
over time. In an initial prospective study, 22 of 45 patients (48.8%)
identified over a three-month period, treated by resection of a
musculoskeletal tumour, had an unidentifiable biopsy site at operation,
with identification statistically more difficult after 50 days.
We therefore introduced the practice of marking the biopsy site
with India ink. In all 55 patients undergoing this procedure, the
biopsy track was identified pre-operatively (100%); this difference
was statistically significant. We recommend this technique as a
safe, easy and accurate means of ensuring adequate excision of the
biopsy track.

Patients who have limb amputation for musculoskeletal
tumours are a rare group of cancer survivors. This was a prospective
cross-sectional survey of patients from five specialist centres
for sarcoma surgery in England. Physical function, pain and quality
of life (QOL) outcomes were collected after lower extremity amputation
for bone or soft-tissue tumours to evaluate the survivorship experience
and inform service provision. Of 250 patients, 105 (42%) responded between September 2012 and
June 2013. From these, completed questionnaires were received from
100 patients with a mean age of 53.6 years (19 to 91). In total
60 (62%) were male and 37 (38%) were female (three not specified).
The diagnosis was primary bone sarcoma in 63 and soft-tissue tumour
in 37. A total of 20 tumours were located in the hip or pelvis,
31 above the knee, 32 between the knee and ankle and 17 in the ankle
or foot. In total 22 had hemipelvectomy, nine hip disarticulation,
35 transfemoral amputation, one knee disarticulation, 30 transtibial
amputation, two toe amputations and one rotationplasty. The Toronto
Extremity Salvage Score (TESS) differed by amputation level, with
poorer scores at higher levels (p <
0.001). Many reported significant
pain. In addition, TESS was negatively associated with increasing
age, and pain interference scores. QOL for Cancer Survivors was
significantly correlated with TESS (p <
0.001). This relationship appeared
driven by pain interference scores. This unprecedented national survey confirms amputation level
is linked to physical function, but not QOL or pain measures. Pain
and physical function significantly impact on QOL. These results
are helpful in managing the expectations of patients about treatment
and addressing their complex needs. Cite this article:
We compared the use of broth culture medium for
samples taken in theatre with the standard practice of placing tissue
samples in universal containers. A total of 67 consecutive patients
had standard multiple samples of deep tissue harvested at surgery
and distributed equally in theatre either to standard universal
containers or to broth culture medium. These samples were cultured
by direct and enrichment methods. The addition of broth in theatre to
standard practice led to an increase in sensitivity from 83% to
95% and an increase in negative predictive value from 77% to 91%.
Placing tissue samples directly into broth in the operating theatre
is a simple, inexpensive way to increase the sensitivity of cultures
from infected patients, and does not appear to compromise the specificity
of these cultures. Cite this article:
Resection of a primary sarcoma of the diaphysis
of a long bone creates a large defect. The biological options for reconstruction
include the use of a vascularised and non-vascularised fibular autograft. The purpose of the present study was to compare these methods
of reconstruction. Between 1985 and 2007, 53 patients (26 male and 27 female) underwent
biological reconstruction of a diaphyseal defect after resection
of a primary sarcoma. Their mean age was 20.7 years (3.6 to 62.4).
Of these, 26 (49 %) had a vascularised and 27 (51 %) a non-vascularised
fibular autograft. Either method could have been used for any patient in
the study. The mean follow-up was 52 months (12 to 259). Oncological,
surgical and functional outcome were evaluated. Kaplan–Meier analysis
was performed for graft survival with major complication as the
end point. At final follow-up, eight patients had died of disease. Primary
union was achieved in 40 patients (75%); 22 (42%) with a vascularised
fibular autograft and 18 (34%) a non-vascularised (p = 0.167). A
total of 32 patients (60%) required revision surgery. Kaplan–Meier
analysis revealed a mean survival without complication of 36 months
(0.06 to 107.3, Both groups seem to be reliable biological methods of reconstructing
a diaphyseal bone defect. Vascularised autografts require more revisions
mainly due to problems with wound healing in distal sites of tumour,
such as the foot. Cite this article:
Local treatment with phenol is often used after intralesional excision of chondroblastomas and giant-cell tumours which involve bone near joints, and has been shown to reduce the rate of recurrence. The ideal concentration of phenol is uncertain, but may be important because of the high rate of absorption and toxicity. We have studied the effectiveness of different concentrations on standard sarcoma cell lines. Our results suggest that a 5% solution of phenol is effective against dispersed single cells, and that higher concentrations give no significant advantage, but create problems due to lack of homogeneous mixing, temperature and safety.
