The primary aim of this study was to determine the morbidity
of a tibial strut autograft and characterize the rate of bony union
following its use. We retrospectively assessed a series of 104 patients from a single
centre who were treated with a tibial strut autograft of > 5 cm
in length. A total of 30 had a segmental reconstruction with continuity
of bone, 27 had a segmental reconstruction without continuity of
bone, 29 had an arthrodesis and 18 had a nonunion. Donor-site morbidity
was defined as any event that required a modification of the postoperative
management. Union was assessed clinically and radiologically at
a median of 36 months (IQR, 14 to 74).Aims
Patients and Methods
The use of a noninvasive growing endoprosthesis in the management
of primary bone tumours in children is well established. However,
the efficacy of such a prosthesis in those requiring a revision
procedure has yet to be established. The aim of this series was
to present our results using extendable prostheses for the revision
of previous endoprostheses. All patients who had a noninvasive growing endoprosthesis inserted
at the time of a revision procedure were identified from our database.
A total of 21 patients (seven female patients, 14 male) with a mean
age of 20.4 years (10 to 41) at the time of revision were included.
The indications for revision were mechanical failure, trauma or infection
with a residual leg-length discrepancy. The mean follow-up was 70
months (17 to 128). The mean shortening prior to revision was 44 mm
(10 to 100). Lengthening was performed in all but one patient with
a mean lengthening of 51 mm (5 to 140).Aims
Patients and Methods
The aim of this study was to establish what happens to patients
in the long term after endoprosthetic replacement for a primary
malignant tumour of bone. We conducted a retrospective analysis of a prospectively maintained
database to identify all patients who had undergone an endoprosthetic
replacement more than 25 years ago and who were still alive. Their
outcomes were investigated with reference to their complications and
need for further surgery. A total of 230 patients were identified.
Their mean age at diagnosis was 20.7 years (five to 62). The most
common diagnosis was osteosarcoma (132). The most common site was
the distal femur (102). Aims
Patients and Methods
Dislocation rates are reportedly lower in patients requiring
proximal femoral hemiarthroplasty than for patients undergoing hip
arthroplasty for neoplasia. Without acetabular replacement, pain
due to acetabular wear necessitating revision surgery has been described.
We aimed to determine whether wear of the native acetabulum following
hemiarthroplasty necessitates revision surgery with secondary replacement
of the acetabulum after proximal femoral replacement (PFR) for tumour
reconstruction. We reviewed 100 consecutive PFRs performed between January 2003
and January 2013 without acetabular resurfacing. The procedure was
undertaken in 74 patients with metastases, for a primary bone tumour
in 20 and for myeloma in six. There were 48 male and 52 female patients,
with a mean age of 61.4 years (19 to 85) and median follow-up of
two years (interquartile range (IQR) 0.5 to 3.7 years). In total,
52 patients presented with a pathological fracture and six presented
with failed fixation of a previously instrumented pathological fracture.Aims
Patients and Methods
We present a retrospective review of patients treated with extracorporeally
irradiated allografts for primary and secondary bone tumours with
the mid- and long-term survivorship and the functional and radiographic
outcomes. A total of 113 of 116 (97.4%) patients who were treated with
extracorporeally irradiated allografts between 1996 and 2014 were
followed up. Forms of treatment included reconstructions, prostheses
and composite reconstructions, both with and without vascularised
grafts. Survivorship was determined by the Kaplan-Meier method.
Clinical outcomes were assessed using the Musculoskeletal Tumor
Society (MSTS) scoring system, the Toronto Extremity Salvage Score
(TESS) and Quality of Life-C30 (QLQ-30) measures. Radiographic outcomes
were assessed using the International Society of Limb Salvage (ISOLS)
radiographic scoring system.Aims
Patients and Methods
The purpose of this study was to review a large cohort of patients
and further assess the correlation between the histological response
to chemotherapy in patients with Ewing’s sarcoma with the overall
(OS) and event-free survival (EFS). All patients treated for Ewing’s sarcoma between 1980 and 2012
were reviewed. Of these, 293 patients without metastases at the
time of diagnosis and treated with chemotherapy and surgery were
included. Patients were grouped according to the percentage of necrosis
after chemotherapy: Group I: 0% to 50%, Group II: 51% to 99% and Group
III: 100%.Aims
Patients and Methods
Vascularised fibular grafts (VFGs ) are a valuable
surgical technique in limb salvage after resection of a tumour.
The primary objective of this multicentre study was to assess the
risk factors for failure and complications for using a VFG after
resection of a tumour. The study involved 74 consecutive patients (45 men and 29 women
with mean age of 23 years (1 to 64) from four tertiary centres for
orthopaedic oncology who underwent reconstruction using a VFG after
resection of a tumour between 1996 and 2011. There were 52 primary
and 22 secondary reconstructions. The mean follow-up was 77 months
(10 to 195). In all, 69 patients (93%) had successful limb salvage; all of
these united and 65 (88%) showed hypertrophy of the graft. The mean
time to union differed between those involving the upper (28 weeks;
12 to 96) and lower limbs (44 weeks; 12 to 250). Fracture occurred
in 11 (15%), and nonunion in 14 (19%) patients. In 35 patients (47%) at least one complication arose, with a
greater proportion in lower limb reconstructions, non-bridging osteosynthesis,
and in children. These complications resulted in revision surgery
in 26 patients (35%). VFG is a successful and durable technique for reconstruction
of a defect in bone after resection of a tumour, but is accompanied
by a significant risk of complications, that often require revision
surgery. Union was not markedly influenced by the need for chemo-
or radiotherapy, but should not be expected during chemotherapy.
Therefore, restricted weight-bearing within this period is advocated. Cite this article:
This paper aims to provide evidence-based guidance for the general orthopaedic surgeon faced with the presentation of a potential soft tissue sarcoma in an extremity.
In this cross sectional study, the impact and the efficacy of a surveillance programme for sarcomas of the extremities was analysed. All patients who had treatment with curative intent for a high-grade sarcoma and were diagnosed before 2014 were included and followed for a minimum of two years.Objectives
Methods
Non-traumatic osteonecrosis of the femoral head
is a potentially devastating condition, the prevalence of which
is increasing. Many joint-preserving forms of treatment, both medical
and surgical, have been developed in an attempt to slow or reverse
its progression, as it usually affects young patients. However, it is important to evaluate the best evidence that is
available for the many forms of treatment considering the variation
in the demographics of the patients, the methodology and the outcomes
in the studies that have been published, so that it can be used
effectively. The purpose of this review, therefore, was to provide an up-to-date,
evidence-based guide to the management, both non-operative and operative,
of non-traumatic osteonecrosis of the femoral head. Cite this article:
Deep vein thrombosis is a common complication
of immobilising the lower limb after surgery. We hypothesised that
intermittent pneumatic compression (IPC) therapy in outpatients
who had undergone surgical repair of acute ruptures of the Achilles
tendon could reduce the incidence of this problem. A total of 150 patients who had undergone surgical repair of
the Achilles tendon were randomised to either treatment with IPC
for six hours per day (n = 74) under an orthosis or treatment as
usual (n = 74) in a plaster cast without IPC. At two weeks post-operatively,
the incidence of deep vein thrombosis was assessed using blinded, double-reported
compression duplex ultrasound. At this point, IPC was discontinued
and all patients were immobilised in an orthosis for a further four
weeks. At six weeks post-operatively, a second compression duplex ultrasound
scan was performed. At two weeks, the incidence of deep vein thrombosis was 21% in
the treated group and 37% in the control group (p = 0.042). Age
over 39 years was found to be a strong risk factor for deep vein
thrombosis (odds ratio (OR) = 4.84, 95% confidence interval (CI)
2.14 to 10.96). Treatment with IPC, corrected for age differences
between groups, reduced the risk of deep vein thrombosis at the
two-week point (OR = 2.60; 95% CI 1.15 to 5.91; p =0.022). At six weeks,
the incidence of deep vein thrombosis was 52% in the treated group
and 48% in the control group (OR 0.94, 95% CI 0.49 to 1.83). IPC
appears to be an effective method of reducing the risk of deep vein
thrombosis in the early stages of post-operative immobilisation
of outpatients. Further research is necessary to elucidate whether
it can confer similar benefits over longer periods of immobilisation
and in a more heterogeneous group of patients. Cite this article:
The aim of the study was to investigate the controversial issue
of whether the pelvic ring should be reconstructed following resection
of the sarcomas of the ilium. From our database, we identified 64 patients who underwent excision
of a tumour involving the ilium between 1976 and 2015. A total of
35 underwent complete resection, of whom 24 were reconstructed with
a non-vascularised fibula graft, and four with extracorporeal irradiation
and reimplantation. A total of 29 patients had a partial resection.
The mean follow-up was 9.2 years (1.1 to 25.6). Functional outcomes
were assessed using the Toronto Extremity Salvation Score (TESS)
at final follow-up. In all, 32 patients (50%) had a chondrosarcoma.Aims
Patients and Methods
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:
Due to the complex anatomy of the pelvis, limb-sparing resections
of pelvic tumours achieving adequate surgical margins, can often
be difficult. The advent of computer navigation has improved the
precision of resection of these lesions, though there is little
evidence comparing resection with or without the assistance of navigation. Our aim was to evaluate the efficacy of navigation-assisted surgery
for the resection of pelvic bone tumours involving the posterior
ilium and sacrum. Using our prospectively updated institutional database, we conducted
a retrospective case control study of 21 patients who underwent
resection of the posterior ilium and sacrum, for the treatment of
a primary sarcoma of bone, between 1987 and 2015. The resection
was performed with the assistance of navigation in nine patients
and without navigation in 12. We assessed the accuracy of navigation-assisted
surgery, as defined by the surgical margin and how this affects
the rate of local recurrence, the disease-free survival and the
effects on peri-and post-operative morbidity. Aims
Patients and Methods
Few studies dealing with chondrosarcoma of the pelvis are currently
available. Different data about the overall survival and prognostic
factors have been published but without a detailed analysis of surgery-related complications.
We aimed to analyse the outcome of a series of pelvic chondrosarcomas
treated at a single institution, with particular attention to the
prognostic factors. Based on a competing risk model, our objective
was to identify risk factors for the development of complications. In a retrospective single-centre study, 58 chondrosarcomas (26
patients alive, 32 patients dead) of the pelvis were reviewed. The
mean follow-up was 13 years (one week to 23.1 years).Aims
Patients and Methods
Previous classification systems of failure of
limb salvage focused primarily on endoprosthetic failures and lacked sufficient
depth for the effective study of the causes of failure. In order
to address these inadequacies, the International Society of Limb
Salvage (ISOLS) formed a committee to recommend revisions of the
previous systems. The purpose of this study was to report on their
recommendations. The modifications were prepared using an earlier,
evidence-based model with subclassification based on the existing
medical literature. Subclassification for all five primary types
of failure of limb salvage following endoprosthetic reconstruction
were formulated and a complementary system was derived for the failure
of biological reconstruction. An additional classification of failure
in paediatric patients was also described. Limb salvage surgery presents a complex array of potential mechanisms
of failure, and a complete and precise classification of types of
failure is required. Earlier classification systems lacked specificity,
and the evidence-based system outlined here is designed to correct
these weaknesses and to provide a means of reporting failures of
limb salvage in order to allow the interpretation of outcome following
reconstructive surgery. Cite this article:
The aims of this retrospective study were to report the feasibility
of using 3D-printing technology for patients with a pelvic tumour
who underwent reconstruction. A total of 35 patients underwent resection of a pelvic tumour
and reconstruction using 3D-printed endoprostheses between September
2013 and December 2015. According to Enneking’s classification of
bone defects, there were three Type I lesions, 12 Type II+III lesions,
five Type I+II lesions, two Type I+II+III lesions, ten type I+II+IV
lesions and three type I+II+III+IV lesions. A total of three patients
underwent reconstruction using an iliac prosthesis, 12 using a standard
hemipelvic prosthesis and 20 using a screw-rod connected hemipelvic
prosthesis.Aims
Patients and Methods
The purpose of this study was to assess whether
the use of a joint-sparing technique such as curettage and grafting was
successful in eradicating giant cell tumours of the proximal femur,
or whether an alternative strategy was more appropriate. Between 1974 and 2012, 24 patients with a giant cell tumour of
the proximal femur were treated primarily at our hospital. Treatment
was either joint sparing or joint replacing. Joint-sparing treatment
was undertaken in ten patients by curettage with or without adjunctive
bone graft. Joint replacement was by total hip replacement in nine patients
and endoprosthetic replacement in five. All 11 patients who presented
with a pathological fracture were treated by replacement. Local recurrence occurred in five patients (21%): two were treated
by hip replacement, three by curettage and none with an endoprosthesis.
Of the ten patients treated initially by curettage, six had a successful
outcome without local recurrence and required no further surgery.
Three eventually needed a hip replacement for local recurrence and
one an endoprosthetic replacement for mechanical failure. Thus 18
patients had the affected joint replaced and only six (25%) retained
their native joint. Overall, 60% of patients without a pathological
fracture who were treated with curettage had a successful outcome. Cite this article:
