Radiotherapy is a well-known local treatment for spinal metastases. However, in the presence of postoperative systemic therapy, the efficacy of radiotherapy on local control (LC) and overall survival (OS) in patients with spinal metastases remains unknown. This study aimed to evaluate the clinical outcomes of post-surgical radiotherapy for spinal metastatic non-small-cell lung cancer (NSCLC) patients, and to identify factors correlated with LC and OS. A retrospective, single-centre review was conducted of patients with spinal metastases from NSCLC who underwent surgery followed by systemic therapy at our institution from January 2018 to September 2022. Kaplan-Meier analysis and log-rank tests were used to compare the LC and OS between groups. Associated factors for LC and OS were assessed using Cox proportional hazards regression analysis.Aims

The aim of this study was to determine the prevalence and impact of tourniquet use in patients undergoing limb salvage surgery with endoprosthetic reconstruction for a tumour around the knee. We retrieved data from the Prophylactic Antibiotic Regimens in Tumor Surgery (PARITY) trial; specifically, differences in baseline characteristics, surgical details, and postoperative functional outcomes between patients who had undergone surgery under tourniquet and those who had not. A linear regression model was created to evaluate the impact of tourniquet use on postoperative Toronto Extremity Salvage Scores (TESSs) while controlling for confounding variables. A negative-binomial regression model was constructed to explore predictors of postoperative length of stay (LOS).Aims

Iliosacral sarcoma resections have been shown to have high rates of local recurrence (LR) and poor overall survival. There is also no universal classification for the resection of pelvic sarcomas invading the sacrum. This study proposes a novel classification system and analyzes the survival and risk of recurrence, when using this system. This is a retrospective analysis of 151 patients (with median follow-up in survivors of 44 months (interquartile range 12 to 77)) who underwent hemipelvectomy with iliosacral resection at a single centre between 2007 and 2019. The proposed classification differentiates the extent of iliosacral resection and defines types S1 to S6 (S1 resection medial and parallel to the sacroiliac joint, S2 resection through the ipsilateral sacral lateral mass to the neuroforamina, S3 resection through the ipsilateral neuroforamina, S4 resection through ipsilateral the spinal canal, and S5 and S6 contralateral sacral resections). Descriptive statistics and the chi-squared test were used for categorical variables, and the Kaplan-Meier survival analysis were performed.Aims
Methods
There is insufficient evidence to support bony reconstruction of the pubis after a type III internal hemipelvectomy (resection of all or part of the pubis). In this study, we compared surgical complications, postoperative pain, and functional outcome in a series of patients who had undergone a type III internal hemipelvectomy with or without bony reconstruction. In a retrospective cohort study, 32 patients who had undergone a type III hemipelvectomy with or without allograft reconstruction (n = 15 and n = 17, respectively) were reviewed. The mean follow-up was 6.7 years (SD 3.8) for patients in the reconstruction group and 6.1 years (SD 4.0) for patients in the non-reconstruction group. Functional outcome was evaluated using the Musculoskeletal Tumor Society (MSTS) scoring system and the level of postoperative pain with a visual analogue scale (VAS).Aim

The aims of the study were to analyze differences in surgical and oncological outcomes, as well as quality of life (QoL) and function in patients with ankle sarcomas undergoing three forms of surgical treatment, minor or major limb salvage surgery (LSS), or amputation. A total of 69 patients with ankle sarcomas, treated between 1981 and 2017 at two tumour centres, were retrospectively reviewed (mean age at surgery: 46.3 years (SD 22.0); 31 females (45%)). Among these 69 patients 25 were analyzed prospectively (mean age at latest follow-up: 61.2 years (SD 20.7); 11 females (44%)), and assessed for mobility using the Prosthetic Limb Users Survey of Mobility (PLUS-M; for amputees only), the Toronto Extremity Salvage Score (TESS), and the University of California, Los Angeles (UCLA) Activity Score. Individual QoL was evaluated in these 25 patients using the five-level EuroQol five-dimension (EQ-5D-5L) and Fragebogen zur Lebenszufriedenheit/Questions on Life Satisfaction (FLZ).Aims
Methods
To investigate the benefits of denosumab in combination with nerve-sparing surgery for treatment of sacral giant cell tumours (GCTs). This is a retrospective cohort study of patients with GCT who presented between January 2011 and July 2017. Intralesional curettage was performed and patients treated from 2015 to 2017 also received denosumab therapy. The patients were divided into three groups: Cohort 1: control group (n = 36); cohort 2: adjuvant denosumab group (n = 9); and cohort 3: neo- and adjuvant-denosumab group (n = 17).Aims

The aim of this study was to describe the use of 3D-printed sacral endoprostheses to reconstruct the pelvic ring and re-establish spinopelvic stability after total We retrospectively reviewed 32 patients who underwent TES in our hospital between January 2015 and December 2017. We divided the patients into three groups on the basis of the method of reconstruction: an endoprosthesis group (n = 10); a combined reconstruction group (n = 14), who underwent non-endoprosthetic combined reconstruction, including anterior spinal column fixation; and a spinopelvic fixation (SPF) group (n = 8), who underwent only SPF. Spinopelvic stability, implant survival (IS), intraoperative haemorrhage rate, and perioperative complication rate in the endoprosthesis group were documented and compared with those of other two groups.Aims

The aims of this study were to evaluate the long-term outcome
of surgery for bone or soft-tissue metastases from renal cell carcinoma
(RCC) and to determine factors that affect prognosis. Between 1993 and 2014, 58 patients underwent surgery for bone
or soft-tissue metastases from RCC at our hospital. There were 46
men and 12 women with a mean age of 60 years (25 to 84). The mean
follow-up period was 52 months (1 to 257). The surgical sites included
the spine (33 patients), appendicular skeleton (ten patients), pelvis (eight
patients), thorax (four patients), and soft tissue (three patients).

Patients and Methods
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
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

Aims. The aim of the study was to compare measures of the quality of
life (QOL) after resection of a chordoma of the mobile spine with
the national averages in the United States and to assess which factors
influenced the QOL, symptoms of anxiety and depression, and coping
with pain post-operatively in these patients. Patients and Methods. A total of 48 consecutive patients who underwent resection of
a primary or recurrent chordoma of the mobile spine between 2000
and 2015 were included. A total of 34 patients completed a survey
at least 12 months post-operatively. The primary outcome was the
EuroQol-5 Dimensions (EQ-5D-3L) questionnaire. Secondary outcomes were
the Patient-Reported Outcome Measurement Information System (PROMIS)
anxiety, depression and pain interference questionnaires. Data which
were recorded included the indication for surgery, the region of
the tumour, the number of levels resected, the status of the surgical
margins, re-operations, complications, neurological
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
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
Children treated for osteosarcoma around the knee often have
a substantial leg-length discrepancy at skeletal maturity. The aim
of this study was to investigate the results of staged skeletal
reconstruction after a leg lengthening procedure using an external
fixator in these patients. We reviewed 11 patients who underwent staged reconstruction with
either an arthroplasty (n = 6) or an arthrodesis (n = 5). A control
group of 11 patients who had undergone wide excision and concurrent
reconstruction with an arthroplasty were matched for gender, location,
and size of tumour. We investigated the change in leg-length discrepancy,
function as assessed by the Musculoskeletal Tumor Society Scale
(MSTS) score and complications.Aims
Patients and Methods
We investigated the functional outcome in patients
who underwent reverse shoulder replacement (RSR) after removal of
a tumour of the proximal humerus. A total of 16 patients (ten women
and six men) underwent this procedure between 1998 and 2011 in our
hospital. Five patients died and one was lost to follow-up. Ten
patients were available for review at a mean follow-up of 46 months
(12 to 136). Eight patients had a primary and two patients a secondary
bone tumour. At final follow up the mean range of active movement was: abduction
78° (30° to 150°); flexion 98° (45° to 180°); external rotation
32° (10° to 60°); internal rotation 51° (10° to 80°). The mean Musculoskeletal
Tumor Society score was 77% (60% to 90%) and the mean Toronto Extremity
Salvage Score was 70% (30% to 91%). Two patients had a superficial
infection and one had a deep infection and underwent a two-stage
revision procedure. In two patients there was loosening of the RSR;
one dislocated twice. All patients had some degree of atrophy or
pseudo-atrophy of the deltoid muscle. Use of a RSR in patients with a tumour of the proximal humerus
gives acceptable results. Cite this article:
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 oncological and functional outcome
of 18 patients, whose malignant bone tumours were excised with the
assistance of navigation, and who were followed up for more than
three years. There were 11 men and seven women, with a mean age
of 31.8 years (10 to 57). There were ten operations on the pelvic
ring and eight joint-preserving limb salvage procedures. The resection
margins were free of tumour in all specimens. The tumours, which
were stage IIB in all patients, included osteosarcoma, high-grade
chondrosarcoma, Ewing’s sarcoma, malignant fibrous histiocytoma
of bone, and adamantinoma. The overall three-year survival rate
of the 18 patients was 88.9% (95% confidence interval (CI) 75.4
to 100). The three-year survival rate of the patients with pelvic malignancy
was 80.0% (95% CI 55.3 to 100), and of the patients with metaphyseal
malignancy was 100%. The event-free survival was 66.7% (95% CI 44.9
to 88.5). Local recurrence occurred in two patients, both of whom
had a pelvic malignancy. The mean Musculoskeletal Tumor Society
functional score was 26.9 points at a mean follow-up of 48.2 months
(22 to 79). We suggest that navigation can be helpful during surgery for
musculoskeletal tumours; it can maximise the accuracy of resection
and minimise the unnecessary sacrifice of normal tissue by providing
precise intra-operative three-dimensional radiological information.
The current indications for functional restoration
of extension of the knee following quadriceps resection or loss require
reappraisal. The contribution of pedicled and free functional muscle
transfer is likely to be over-emphasised in many studies, with good
functional outcomes predominantly reported only in the context of
cases with residual quadriceps function. In cases with total quadriceps
resection or loss, all forms of reconstruction perform poorly. Furthermore,
in smaller resections with loss of two or fewer components of the
quadriceps, minimal impairment of function occurs in the absence
of functional reconstruction, suggesting that functional restoration
may not be warranted. Thus there is a paradox in the current approach
to quadriceps reconstruction, in that small resections are likely
to be over-treated and large resections remain under-treated. This review suggests a shift is required in the approach and
rationale for reconstructing functional extension of the knee after
quadriceps resection or loss. A classification based on current
evidence is suggested that emphasises more clearly the indications
and rationale for functional transfers.
The aim of this study was to define the treatment
criteria for patients with recurrent chondrosarcoma. We reviewed the
data of 77 patients to examine the influence of factors such as
the intention of treatment (curative/palliative), extent of surgery,
resection margins, status of disease at the time of local recurrence
and the grade of the tumour. A total of 70 patients underwent surgery
for recurrent chondrosarcoma. In seven patients surgery was not
a viable option. Metastatic disease occurred in 41 patients, appearing
synchronously with the local recurrence in 56% of cases. For patients
without metastasis at the time of local recurrence, the overall
survival at a mean follow-up after recurrence of 67 months (0 to
289) was 74% (5 of 27) compared with 19% (13 of 50) for patients
with metastasis at or before the development of the recurrence.
Neither the type/extent of surgery, site of tumour, nor the resection margins
for the recurrent tumour significantly influenced the overall survival. . With limited survival for patients with metastatic disease at
the time of local recurrence (0% for patients with grade III and
de-differentiated chondrosarcoma), palliative treatment, including
local radiation therapy and debulking procedures, should be discussed
with the patients to avoid long hospitalisation and functional
