The consensus is that bipolar hemiarthroplasty (BHA) in allograft-prosthesis composite (APC) reconstruction of the proximal femur following primary tumour resection provides more stability than total hip arthroplasty (THA). However, no comparative study has been performed. In this study, we have compared the outcome and complication rates of these two methods. In a retrospective study, 57 patients who underwent APC reconstruction of proximal femur following the primary tumour resection, either using BHA (29) or THA (28), were included. Functional outcome was assessed using the Musculoskeletal Tumour Society (MSTS) scoring system and Harris Hip Score (HHS). Postoperative complications of the two techniques were also compared.Aims
Methods
We aimed to examine the long-term mechanical survivorship, describe the modes of all-cause failure, and identify risk factors for mechanical failure of all-polyethylene tibial components in endoprosthetic reconstruction. This is a retrospective database review of consecutive endoprosthetic reconstructions performed for oncological indications between 1980 and 2019. Patients with all-polyethylene tibial components were isolated and analyzed for revision for mechanical failure. Outcomes included survival of the all-polyethylene tibial component, revision surgery categorized according to the Henderson Failure Mode Classification, and complications and functional outcome, as assessed by the Musculoskeletal Tumor Society (MSTS) score at the final follow-up.Aims
Methods
The aims of this study were to analyse the long-term outcome
of vascularised fibular graft (VFG) reconstruction after tumour
resection and to evaluate the usefulness of the method. We retrospectively reviewed 49 patients who had undergone resection
of a sarcoma and reconstruction using a VFG between 1988 and 2015.
Their mean follow-up was 98 months (5 to 317). Reconstruction was
with an osteochondral graft (n = 13), intercalary graft (n = 12),
inlay graft (n = 4), or resection arthrodesis (n = 20). We analysed
the oncological and functional outcome, and the rate of bony union
and complications.Aims
Patients and Methods
Pigmented villonodular synovitis (PVNS) is a
rare benign disease of the synovium of joints and tendon sheaths, which
may be locally aggressive. We present 18 patients with diffuse-type
PVNS of the foot and ankle followed for a mean of 5.1 years (2 to
11.8). There were seven men and 11 women, with a mean age of 42
years (18 to 73). A total of 13 patients underwent open or arthroscopic
synovectomy, without post-operative radiotherapy. One had surgery
at the referring unit before presentation with residual tibiotalar
PVNS. The four patients who were managed non-operatively remain
symptomatically controlled and under clinical and radiological surveillance.
At final follow-up the mean Musculoskeletal Tumour Society score
was 93.8% (95% confidence interval (CI) 85 to 100), the mean Toronto
Extremity Salvage Score was 92 (95% CI 82 to 100) and the mean American
Academy of Orthopaedic Surgeons foot and ankle score was 89 (95%
CI 79 to 100). The lesion in the patient with residual PVNS resolved radiologically
without further intervention six years after surgery. Targeted synovectomy
without adjuvant radiotherapy can result in excellent outcomes,
without recurrence. Asymptomatic patients can be successfully managed
non-operatively. This is the first series to report clinical outcome
scores for patients with diffuse-type PVNS of the foot and ankle. Cite this article:
The aim of this study was to explore the prognostic factors for postoperative neurological recovery and survival in patients with complete paralysis due to neoplastic epidural spinal cord compression. The medical records of 135 patients with complete paralysis due to neoplastic cord compression were retrospectively reviewed. Potential factors including the timing of surgery, muscular tone, and tumour characteristics were analyzed in relation to neurological recovery using logistical regression analysis. The association between neurological recovery and survival was analyzed using a Cox model. A nomogram was formulated to predict recovery.Aims
Patients and Methods
To assess complications and failure mechanisms of osteoarticular
allograft reconstructions for primary bone tumours. We retrospectively evaluated 38 patients (28 men, 74%) who were
treated at our institution with osteoarticular allograft reconstruction
between 1989 and 2010. Median age was 19 years (interquartile range
14 to 32). Median follow-up was 19.5 years (95% confidence interval
(CI) 13.0 to 26.1) when 26 patients (68%) were alive. In addition, we
systematically searched the literature for clinical studies on osteoarticular
allografts, finding 31 studies suitable for analysis. Results of
papers that reported on one site exclusively were pooled for comparison.Aims
Patients and Methods
The February 2014 Oncology Roundup360 looks at: suspicious lesions; limb salvage in pelvic sarcomas; does infection affect oncological survival?; cancer patient pathways; radiological arthritis with cement augmentation in GCT; and post-chemotherapy increase in tumour volume as a predictor of poor prognosis.
Total Of the 54 patients who underwent TES for a primary tumour between
1993 and 2010, 19 died and four were lost to follow-up. In January
2012, a questionnaire was sent to the 31 surviving patients. This
included the short form-36 to assess HRQoL and questions about the
current condition of their disease, activities of daily living (ADL)
and surgery. The response rate was high at 83.9% (26/31 patients).
We found that most patients were satisfied and maintained good performance
of their ADLs. The mental health status and social roles of the HRQoL scores
were nearly equivalent to those of healthy individuals, regardless
of the time since surgery. There was significant impairment of physical
health in the early post-operative years, but this usually returned
to normal approximately three years after surgery. Cite this article:
Aims
Patients and Methods
The ageing population and an increase in both
the incidence and prevalence of cancer pose a healthcare challenge, some
of which is borne by the orthopaedic community in the form of osteoporotic
fractures and metastatic bone disease. In recent years there has
been an increasing understanding of the pathways involved in bone
metabolism relevant to osteoporosis and metastases in bone. Newer
therapies may aid the management of these problems. One group of
drugs, the antibody mediated anti-resorptive therapies (AMARTs)
use antibodies to block bone resorption pathways. This review seeks
to present a synopsis of the guidelines, pharmacology and potential pathophysiology
of AMARTs and other new anti-resorptive drugs. We evaluate the literature relating to AMARTs and new anti-resorptives
with special attention on those approved for use in clinical practice. Denosumab, a monoclonal antibody against Receptor Activator for
Nuclear Factor Kappa-B Ligand. It is the first AMART approved by
the National Institute for Health and Clinical Excellence and the
US Food and Drug Administration. Other novel anti-resorptives awaiting
approval for clinical use include Odanacatib. Denosumab is indicated for the treatment of osteoporosis and
prevention of the complications of bone metastases. Recent evidence
suggests, however, that denosumab may have an adverse event profile
similar to bisphosphonates, including atypical femoral fractures.
It is, therefore, essential that orthopaedic surgeons are conversant
with these medications and their safe usage. Take home message: Denosumab has important orthopaedic indications
and has been shown to significantly reduce patient morbidity in
osteoporosis and metastatic bone disease. Cite this article:
We retrospectively studied 14 patients with proximal and diaphyseal tumours and disappearing bone (Gorham’s) disease of the humerus treated with wide resection and reconstruction using an allograft-resurfacing composite (ARC). There were ten women and four men, with a mean age of 35 years (8 to 69). At a mean follow-up of 25 months (10 to 89), two patients had a fracture of the allograft. In one of these it was revised with a similar ARC and in the other with an intercalary prosthesis. A further patient had an infection and a fracture of the allograft that was revised with a megaprosthesis. In all patients with an ARC, healing of the ARC-host bone interface was observed. One patient had failure of the locking mechanism of the total elbow replacement. The mean post-operative Musculoskeletal Tumor Society score for the upper extremity was 77% (46.7% to 86.7%), which represents good and excellent results; one patient had a poor result (46.7%). In the short term ARC effectively relieves pain and restores shoulder function in patients with wide resection of the proximal humerus. Fracture and infection remain significant complications.
The December 2012 Trauma Roundup360 looks at: more is not always better, especially when its chemotherapy; new hope for skeletal metastasis; biopsy tracts; intra-operative imaging of sarcomas; curettage with adjuvant therapy; amputation and distal tibial osteosarcoma; and diaphyseal tibial tumours.
Bone loss secondary to primary or metastatic lesions of the proximal humerus remains a challenging surgical problem. Options include preservation of the joint with stabilisation using internal fixation or resection of the tumour with prosthetic replacement. Resection of the proximal humerus often includes the greater tuberosity and adjacent diaphysis, which may result in poor function secondary to loss of the rotator cuff and/or deltoid function. Preservation of the joint with internal fixation may reduce the time in hospital and peri-operative morbidity compared with joint replacement, and result in a better functional outcome. We included 32 patients with pathological fractures of the proximal humerus in this study. Functional and radiological assessments were performed. At a mean follow-up of 17.6 months (8 to 61) there was no radiological evidence of failure of fixation. The mean revised musculoskeletal Tumour Society functional score was 94.6% (86% to 99%). There was recurrent tumour requiring further surgery in four patients (12.5%). Of the 22 patients who were employed prior to presentation all returned to work without restrictions. The use of a locking plate combined with augmentation with cement extends the indications for salvage of the proximal humerus with good function in patients with pathological and impending pathological fractures.
The sacrum is frequently invaded by a pelvic tumour. The aim
of this study was to review our experience of treating this group
of patients and to identify the feasibility of a new surgical classification
in the management of these tumours. We reviewed 141 patients who, between 2005 and 2014, had undergone
surgical excision of a pelvic tumour with invasion of the sacrum. In a new classification, pelvisacral (Ps) I, II, and III resections
refer to a sagittal osteotomy through the ipsilateral wing of the
sacrum, through the sacral midline, or lateral to the contralateral
sacral foramina, respectively. A Ps a resection describes a pelvic
osteotomy through the ilium and a Ps b resection describes a concurrent
resection of the acetabulum with osteotomies performed through the
pubis and ischium or the pubic symphysis. Within each type, surgical
approaches were standardized to guide resection of the tumour.Aims
Patients and Methods
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:
The primary aim of this study was to determine the effect of
the duration of symptoms (DOS) prior to diagnosis on the overall
survival in patients with a primary bone sarcoma. In a retrospective analysis of a sarcoma database at a single
institution between 1990 and 2014, we identified 1446 patients with
non-metastatic and 346 with metastatic bone sarcoma. Low-grade types
of tumour were excluded. Our data included the demographics of the
patients, the characteristics of the tumour, and the survival outcome
of patients. Cox proportional hazards analysis and Kaplan–Meier
survival analysis were performed, and the survivorship of the non-metastatic
and metastatic cohorts were compared.Aims
