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.

We aimed to assess the influence of ethnicity on the incidence
of heterotopic ossification (HO) after total hip arthroplasty (THA). We studied the six-month post-operative anteroposterior radiographs
of 1449 consecutive primary THAs (1324 patients) and retrospectively
graded them for the presence of HO, using the Brooker Classification. Aims
Patients and Methods
The purpose of this study was to assess the outcome
of 15 patients (mean age 13.6 years (7 to 25)) with a primary sarcoma
of the tibial diaphysis who had undergone excision of the affected
segment that was then irradiated (90 Gy) and reimplanted with an
ipsilateral vascularised fibular graft within it. The mean follow-up was 57 months (22 to 99). The mean time to
full weight-bearing was 23 weeks (9 to 57) and to complete radiological
union 42.1 weeks (33 to 55). Of the 15 patients, seven required
a further operation, four to obtain skin cover. The mean Musculoskeletal
Society Tumor Society functional score at final follow-up was 27
out of 30 once union was complete. The functional results were comparable
with those of allograft reconstruction and had a similar rate of
complication. We believe this to be a satisfactory method of biological reconstruction
of the tibial diaphysis in selected patients.
To date, all surgical techniques used for reconstruction
of the pelvic ring following supra-acetabular tumour resection produce
high complication rates. We evaluated the clinical, oncological
and functional outcomes of a cohort of 35 patients (15 men and 20
women), including 21 Ewing’s sarcomas, six chondrosarcomas, three sarcomas
not otherwise specified, one osteosarcoma, two osseous malignant
fibrous histiocytomas, one synovial cell sarcoma and one metastasis.
The mean age of the patients was 31 years (8 to 79) and the latest
follow-up was carried out at a mean of 46 months (1.9 to 139.5)
post-operatively. We undertook a functional reconstruction of the pelvic ring using
polyaxial screws and titanium rods. In 31 patients (89%) the construct
was encased in antibiotic-impregnated polymethylmethacrylate. Preservation
of the extremities was possible for all patients. The survival rate
at three years was 93.9% (95% confidence interval (CI) 77.9 to 98.4),
at five years it was 82.4% (95% CI 57.6 to 93.4). For the 21 patients
with Ewing’s sarcoma it was 95.2% (95% CI 70.7 to 99.3) and 81.5%
(95% CI 52.0 to 93.8), respectively. Wound healing problems were
observed in eight patients, deep infection in five and clinically
asymptomatic breakage of the screws in six. The five-year implant survival
was 93.3% (95% CI 57.8 to 95.7). Patients were mobilised at a mean
of 3.5 weeks (1 to 7) post-operatively. A post-operative neurological
defect occurred in 12 patients. The mean Musculoskeletal Tumor Society
score at last available follow-up was 21.2 (10 to 27). This reconstruction technique is characterised by simple and
oncologically appropriate applicability, achieving high primary
stability that allows early mobilisation, good functional results
and relatively low complication rates. Cite this article:
We evaluated the risk of late relapse and further
outcome in patients with soft-tissue sarcomas who were alive and event-free
more than five years after initial treatment. From our database
we identified 1912 patients with these pathologies treated between
1980 and 2006. Of these 1912 patients, 603 were alive and event-free
more than five years after initial treatment and we retrospectively
reviewed them. The mean age of this group was 48 years (4 to 94)
and 340 were men. The mean follow-up was 106 months (60 to 336).
Of the original cohort, 582 (97%) were alive at final follow-up.
The disease-specific survival was 96.4% (95% confidence interval
(CI) 94.4 to 98.3) at ten years and 92.9% (95% CI 89 to 96.8) at
15 years. The rate of late relapse was 6.3% (38 of 603). The ten-
and 15-year event-free rates were 93.2% (95% CI 90.8 to 95.7) and
86.1% (95% CI 80.2 to 92.1), respectively. Multivariate analysis
showed that tumour size and tumour grade remained independent predictors
of events. In spite of further treatment, 19 of the 38 patients
died of sarcoma. The three- and five-year survival rates after the
late relapse were 56.2% (95% CI 39.5 to 73.3) and 43.2% (95% CI
24.7 to 61.7), respectively, with a median survival time of 46 months.
Patients with soft-tissue sarcoma, especially if large, require
long-term follow-up, especially as they have moderate potential
to have their disease controlled. Cite this article:
Heterotopic ossification (HO) is perhaps the
single most significant obstacle to independence, functional mobility, and
return to duty for combat-injured veterans of Operation Enduring
Freedom and Operation Iraqi Freedom. Recent research into the cause(s)
of HO has been driven by a markedly higher prevalence seen in these
wounded warriors than encountered in previous wars or following
civilian trauma. To that end, research in both civilian and military
laboratories continues to shed light onto the complex mechanisms
behind HO formation, including systemic and wound specific factors,
cell lineage, and neurogenic inflammation. Of particular interest,

Wound complications are reported in up to 10% hip and knee arthroplasties and there is a proven association between wound complications and deep prosthetic infections. In this randomised controlled trial (RCT) we explore the potential benefits of a portable, single use, incisional negative pressure wound therapy dressing (iNPWTd) on wound exudate, length of stay (LOS), wound complications, dressing changes and cost-effectiveness following total hip and knee arthroplasties. A total of 220 patients undergoing elective primary total hip and knee arthroplasties were recruited into in a non-blinded RCT. For the final analysis there were 102 patients in the study group and 107 in the control group.Objectives

Cancellous allograft bone chips are commonly
used in the reconstruction of defects in bone after removal of benign tumours.
We investigated the MRI features of grafted bone chips and their
change over time, and compared them with those with recurrent tumour.
We retrospectively reviewed 66 post-operative MRIs from 34 patients
who had undergone curettage and grafting with cancellous bone chips
to fill the defect after excision of a tumour. All grafts showed
consistent features at least six months after grafting: homogeneous
intermediate or low signal intensities with or without scattered
hyperintense foci (speckled hyperintensities) on T1 images; high
signal intensities with scattered hypointense foci (speckled hypointensities)
on T2 images, and peripheral rim enhancement with or without central
heterogeneous enhancements on enhanced images. Incorporation of
the graft occurred from the periphery to the centre, and was completed
within three years. Recurrent lesions consistently showed the same signal
intensities as those of pre-operative MRIs of the primary lesions.
There were four misdiagnoses, three of which were chondroid tumours. We identified typical MRI features and clarified the incorporation
process of grafted cancellous allograft bone chips. The most important
characteristics of recurrent tumours were that they showed the same
signal intensities as the primary tumours. It might sometimes be
difficult to differentiate grafted cancellous allograft bone chips
from a recurrent chondroid tumour. Cite this article:
Surgical intervention in patients with bone metastases from breast
cancer is dependent on the estimated survival of the patient. The
purpose of this paper was to identify factors that would predict
survival so that specific decisions could be made in terms of surgical
(or non-surgical) management. The records of 113 consecutive patients (112 women) with metastatic
breast cancer were analysed for clinical, radiological, serological
and surgical outcomes. Their median age was 61 years (interquartile
range 29 to 90) and the median duration of follow-up was 1.6 years

The best method of reconstruction after resection of malignant tumours of the tibial diaphysis is unknown. In the absence of any long-term studies analysing the results of intercalary endoprosthetic replacement, we present a retrospective review of 18 patients who underwent limb salvage using a tibial diaphyseal endoprosthetic replacement following excision of a malignant bone tumour. There were ten men and eight women with a mean age of 42.5 years (16 to 76). Mean follow-up was 58.5 months (20 to 141) for all patients and 69.3 months (20 to 141) for the 12 patients still alive. Cumulative patient survival was 59% (95% confidence interval (CI) 32 to 84) at five years. Implant survival was 63% (95% CI 35 to 90) at ten years. Four patients required revision to a proximal tibial replacement at a mean follow-up of 29 months (10 to 54). Complications included metastases in five patients, aseptic loosening in four, peri-prosthetic fracture in two, infection in one and local recurrence in one. The mean Musculoskeletal Tumor Society score and the mean Toronto Extremity Salvage Score were 23 (17 to 28) and 74% (53 to 91), respectively. Although rates of complication and revision were high, custom-made tibial diaphyseal replacement following resection of malignant bone tumours enables early return to function and provides an attractive alternative to other surgical options, without apparent compromise of patient survival.
The management of open lower limb fractures in the United Kingdom
has evolved over the last ten years with the introduction of major
trauma networks (MTNs), the publication of standards of care and
the wide acceptance of a combined orthopaedic and plastic surgical approach
to management. The aims of this study were to report recent changes
in outcome of open tibial fractures following the implementation
of these changes. Data on all patients with an open tibial fracture presenting
to a major trauma centre between 2011 and 2012 were collected prospectively.
The treatment and outcomes of the 65 Gustilo Anderson Grade III
B tibial fractures were compared with historical data from the same

We performed a systematic review of the literature to determine the safety and efficacy of bone morphogenetic protein (BMP) compared with bone graft when used specifically for revision spinal fusion surgery secondary to pseudarthrosis. The MEDLINE, EMBASE and Cochrane Library databases were searched using defined search terms. The primary outcome measure was spinal fusion, assessed as success or failure in accordance with radiograph, MRI or CT scan review at 24-month follow-up. The secondary outcome measure was time to fusion.Objectives

The aim of this study was to evaluate the prognostic
and therapeutic factors which influence the oncological outcome
of parosteal osteosarcoma. A total of 80 patients with a primary parosteal osteosarcoma
were included in this retrospective study. There were 51 females
and 29 males with a mean age of 29.9 years (11 to 78). The mean follow-up was 11.2 years (1 to 40). Overall survival
was 91.8% at five years and 87.8% at ten years. Local recurrence
occurred in 14 (17.5%) patients and was associated with intralesional
surgery and a large volume of tumour. On histological examination,
80% of the local recurrences were dedifferentiated high-grade tumours.
A total of 12 (14.8%) patients developed pulmonary metastases, of
whom half had either a dedifferentiated tumour or a local recurrence.
Female gender and young age were good prognostic factors. Local
recurrence was a poor prognostic factor for survival. Medullary
involvement or the use of chemotherapy had no impact on survival. The main goal in treating a parosteal osteosarcoma must be to
achieve a wide surgical margin, as inadequate margins are associated
with local recurrence. Local recurrence has a significant negative
effect on survival, as 80% of the local recurrences are high-grade
dedifferentiated tumours, and half of these patients develop metastases. The role of chemotherapy in the treatment of parosteal osteosarcoma
is not as obvious as it is in the treatment of conventional osteosarcoma.
The mainstay of treatment is wide local excision. Cite this article:
We retrospectively reviewed 30 patients with
a diffuse-type giant-cell tumour (Dt-GCT) (previously known as pigmented
villonodular synovitis) around the knee in order to assess the influence
of the type of surgery on the functional outcome and quality of
life (QOL). Between 1980 and 2001, 15 of these tumours had been
treated primarily at our tertiary referral centre and 15 had been
referred from elsewhere with recurrent lesions. The mean follow-up was 64 months (24 to 393). Functional outcome
and QOL were assessed with range of movement and the Knee injury
and Osteoarthritis Outcome Score (KOOS), the Musculoskeletal Tumour
Society (MSTS) score, the Toronto Extremity Salvage Score (TESS)
and the SF-36 questionnaire. There was recurrence in four of 14
patients treated initially by open synovectomy. Local control was
achieved after a second operation in 13 of 14 (93%). Recurrence
occurred in 15 of 16 patients treated initially by arthroscopic
synovectomy. These patients underwent a mean of 1.8 arthroscopies
(one to eight) before open synovectomy. This achieved local control
in 8 of 15 (53%) after the first synovectomy and in 12 of 15 (80%)
after two. The functional outcome and QOL of patients who had undergone
primary arthroscopic synovectomy and its attendant subsequent surgical
procedures were compared with those who had had a primary open synovectomy
using the following measures: range of movement (114º Those who had undergone open synovectomy needed fewer subsequent
operations. Most patients who had been referred with a recurrence
had undergone an initial arthroscopic synovectomy followed by multiple
further synovectomies. At the final follow-up of eight years (2
to 32), these patients had impaired function and QOL compared with
those who had undergone open synovectomy initially. We conclude that the natural history of Dt-GCT in patients who
are treated by arthroscopic synovectomy has an unfavourable outcome,
and that primary open synovectomy should be undertaken to prevent
recurrence or residual disease. 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:
We identified eight patients of 2900 with a primary malignant bone tumour who had coexisting neurofibromatosis type 1. This was a much higher incidence than would be expected by chance. The patients had a mean age of 22.4 years (9 to 54): five were male. Two patients subsequently developed a second bone sarcoma, one of which was radiation induced. Four of the primary tumours were osteosarcomas, four were spindle-cell sarcomas and one a Ewing’s sarcoma. All the patients were treated with chemotherapy and surgery: six of the eight appear to be cured. This study suggests a possible relationship between neurofibromatosis type 1 and the development of a bone sarcoma, the increased risk being estimated at eight times that of the normal population. We recommend that further research into this possible link should be considered.
