The scapula is a rare site for a primary bone tumour. Only a small number of series have studied patient outcomes after treatment. Previous studies have shown a high rate of recurrence, with functional outcomes determined by the preservation of the glenohumeral joint and deltoid. The purpose of the current study was to report the outcome of patients who had undergone tumour resection that included the scapula. We reviewed 61 patients (37 male, 24 female; mean age 42 years (SD 19)) who had undergone resection of the scapula. The most common resection was type 2 (n = 34) according to the Tikhoff-Linberg classification, or type S1A (n = 35) on the Enneking classification.Aims
Methods
Dislocation of the hip remains a major complication after periacetabular tumour resection and endoprosthetic reconstruction. The position of the acetabular component is an important modifiable factor for surgeons in determining the risk of postoperative dislocation. We investigated the significance of horizontal, vertical, and sagittal displacement of the hip centre of rotation (COR) on postoperative dislocation using a CT-based 3D model, as well as other potential risk factors for dislocation. A total of 122 patients who underwent reconstruction following resection of periacetabular tumour between January 2011 and January 2020 were studied. The risk factors for dislocation were investigated with univariate and multivariate logistic regression analysis on patient-specific, resection-specific, and reconstruction-specific variables.Aims

The aim of this study was to report the patterns of symptoms and insufficiency fractures in patients with tumour-induced osteomalacia (TIO) to allow the early diagnosis of this rare condition. The study included 33 patients with TIO who were treated between January 2000 and June 2022. The causative tumour was detected in all patients. We investigated the symptoms and evaluated the radiological patterns of insufficiency fractures of the rib, spine, and limbs.Aims
Methods
The sacroiliac joint (SIJ) is the only mechanical connection between the axial skeleton and lower limbs. Following iliosacral resection, there is debate on whether reconstruction of the joint is necessary. There is a paucity of data comparing the outcomes of patients undergoing reconstruction and those who are not formally reconstructed. A total of 60 patients (25 females, 35 males; mean age 39 years (SD 18)) undergoing iliosacral resection were reviewed. Most resections were performed for primary malignant tumours (n = 54; 90%). The mean follow-up for surviving patients was nine years (2 to 19).Aims

Aims. Instability of the hip is the most common mode of failure after
reconstruction with a proximal femoral arthroplasty (PFA) using
an endoprosthesis after excision of a tumour. Small studies report
improved stability with capsular
The aim of this study was to investigate the feasibility of application of a 3D-printed megaprosthesis with hemiarthroplasty design for defects of the distal humerus or proximal ulna following tumour resection. From June 2018 to January 2020, 13 patients with aggressive or malignant tumours involving the distal humerus (n = 8) or proximal ulna (n = 5) were treated by en bloc resection and reconstruction with a 3D-printed megaprosthesis with hemiarthroplasty, designed in our centre. In this paper, we summarize the baseline and operative data, oncological outcome, complication profiles, and functional status of these patients.Aims
Methods
Proximal femoral endoprosthetic replacements (PFEPRs) are the most common reconstruction option for osseous defects following primary and metastatic tumour resection. This study aimed to compare the rate of implant failure between PFEPRs with monopolar and bipolar hemiarthroplasties and acetabular arthroplasties, and determine the optimum articulation for revision PFEPRs. This is a retrospective review of 233 patients who underwent PFEPR. The mean age was 54.7 years (SD 18.2), and 99 (42.5%) were male. There were 90 patients with primary bone tumours (38.6%), 122 with metastatic bone disease (52.4%), and 21 with haematological malignancy (9.0%). A total of 128 patients had monopolar (54.9%), 74 had bipolar hemiarthroplasty heads (31.8%), and 31 underwent acetabular arthroplasty (13.3%).Aims
Methods
The aim of this study was to report the results of three forms of reconstruction for patients with a ditsl tibial bone tumour: an intercalary resection and reconstruction, an osteoarticular reconstruction, and arthrodesis of the ankle. A total of 73 patients with a median age of 19 years (interquartile range (IQR) 14 to 36) were included in this retrospective, multicentre study.Aims
Methods
Iliac wing (Type I) and iliosacral (Type I/IV) pelvic resections for a primary bone tumour create a large segmental defect in the pelvic ring. The management of this defect is controversial as the surgeon may choose to reconstruct it or not. When no reconstruction is undertaken, the residual ilium collapses back onto the remaining sacrum forming an iliosacral pseudarthrosis. The aim of this study was to evaluate the long-term oncological outcome, complications, and functional outcome after pelvic resection without reconstruction. Between 1989 and 2015, 32 patients underwent a Type I or Type I/IV pelvic resection without reconstruction for a primary bone tumour. There were 21 men and 11 women with a mean age of 35 years (15 to 85). The most common diagnosis was chondrosarcoma (50%, n = 16). Local recurrence-free, metastasis-free, and overall survival were assessed using the Kaplan-Meier method. Patient function was evaluated using the Musculoskeletal Tumour Society (MSTS) and Toronto Extremity Salvage Score (TESS).Aims
Methods
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
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
Methods
We analyzed the long-term outcomes of patients observed over ten years after resection en bloc and reconstruction with extracorporeal irradiated autografts 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 Musculoskeletal Tumor Society (MSTS) scoring system.Aims
Patients and Methods
The aim of this study was to evaluate the efficacy of the surgical dislocation approach and modified trapdoor procedure for the treatment of chondroblastoma of the femoral head. A total of 17 patients (ten boys, seven girls; mean age 16.4 years (11 to 26)) diagnosed with chondroblastoma of the femoral head who underwent surgical dislocation of the hip joint, modified trapdoor procedure, curettage, and bone grafting were enrolled in this study and were followed-up for a mean of 35.9 months (12 to 76). Healing and any local recurrence were assessed via clinical and radiological tests. Functional outcome was evaluated using the Musculoskeletal Tumour Society scoring system (MSTS). Patterns of bone destruction were evaluated using the Lodwick classification. Secondary osteoarthritis was classified via radiological analysis following the Kellgren–Lawrence grading system. Steinberg classification was used to evaluate osteonecrosis of the femoral head.Aims
Patients and Methods
After intercalary resection of a bone tumour from the femur,
reconstruction with a vascularized fibular graft (VFG) and massive
allograft is considered a reliable method of treatment. However,
little is known about the long-term outcome of this procedure. The
aims of this study were to determine whether the morbidity of this
procedure was comparable to that of other reconstructive techniques,
if it was possible to achieve a satisfactory functional result, and
whether biological reconstruction with a VFG and massive allograft
could achieve a durable, long-lasting reconstruction. A total of 23 patients with a mean age of 16 years (five to 40)
who had undergone resection of an intercalary bone tumour of the
femur and reconstruction with a VFG and allograft were reviewed
clinically and radiologically. The mean follow-up was 141 months
(24 to 313). The mean length of the fibular graft was 18 cm (12 to
29). Full weight-bearing without a brace was allowed after a mean
of 13 months (seven to 26).Aims
Patients and Methods
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. 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 deficit, length
of stay in hospital and rate of re-admission.Aims
Patients and Methods
Free vascularised fibular grafting has been used for the treatment
of large bony defects for more than 40 years. However, there is
little information about the risk factors for failure and whether
newer locking techniques of fixation improve the rates of union.
The purpose of this study was to compare the rates of union of free
fibular grafts fixed with locking and traditional techniques, and
to quantify the risk factors for nonunion and failure. A retrospective review involved 134 consecutive procedures over
a period of 20 years. Of these, 25 were excluded leaving 109 patients
in the study. There were 66 men and 43 women, with a mean age of
33 years (5 to 78). Most (62) were performed for oncological indications,
and the most common site (52) was the lower limb. Rate of union
was estimated using the Kaplan-Meier method and risk factors for
nonunion were assessed using Cox regression. All patients were followed
up for at least one year.Aims
Patients and Methods
We determined the efficacy of a devitalised autograft
(n = 13) and allograft (n = 16) cortical strut bone graft combined
with long-stem endoprosthetic reconstruction in the treatment of
massive tumours of the lower limb. A total of 29 patients (18 men:11
women, mean age 20.1 years (12 to 45) with a ratio of length of
resection to that of the whole prosthesis of >
50% were treated
between May 2003 and May 2012. The mean follow-up was 47 months
(15 to 132). The stem of the prosthesis was introduced through bone
graft struts filled with cement, then cemented into the residual
bone. Bone healing was achieved in 23 patients (86%). The mean Musculoskeletal
Tumour Society functional score was 85% (57 to 97). The five-year
survival rate of the endoprostheses was 81% (95% confidence intervals
67.3 to 92.3). The mean length of devitalised autografts and allografts
was 8.6 cm (5 to 15), which increased the ratio of the the length
of the stem of the prosthesis to that of the whole length of the
prosthesis from a theoretical 35% to an actual 55%. Cortical strut bone grafting and long-stem endoprosthetic reconstruction
is an option for treating massive segmental defects following resection
of a tumour in the lower limb. Patients can regain good function
with a low incidence of aseptic loosening. The strut graft and the
residual bone together serve as a satisfactory bony environment
for a revision prosthesis, if required, once union is achieved. Cite this article:
We evaluated the clinical results and complications
after extra-articular resection of the distal femur and/or proximal
tibia and reconstruction with a tumour endoprosthesis (MUTARS) in
59 patients (mean age 33 years (11 to 74)) with malignant bone or
soft-tissue tumours. According to a Kaplan–Meier analysis, limb
survival was 76% (95% confidence interval (CI) 64.1 to 88.5) after
a mean follow-up of 4.7 years (one month to 17 years). Peri-prosthetic infection
was the most common indication for subsequent amputation (eight
patients). Survival of the prosthesis without revision was 48% (95%
CI 34.8 to 62.0) at two years and 25% (95% CI 11.1 to 39.9) at five years
post-operatively. Failure of the prosthesis was due to deep infection
in 22 patients (37%), aseptic loosening in ten patients (17%), and
peri-prosthetic fracture in six patients (10%). Wear of the bearings
made a minor revision necessary in 12 patients (20%). The mean Musculoskeletal
Tumor Society score was 23 (10 to 29). An extensor lag >
10° was
noted in ten patients (17%). These results suggest that limb salvage after extra-articular
resection with a tumour prosthesis can achieve good functional results
in most patients, although the rates of complications and subsequent
amputation are higher than in patients treated with intra-articular
resection. Cite this article:
We retrospectively reviewed the outcomes of 33
consecutive patients who had undergone an extra-articular, total or
partial scapulectomy for a malignant tumour of the shoulder girdle
between 1 July 2001 and 30 September 2013. Of these, 26 had tumours
which originated in the scapula or the adjacent soft tissue and
underwent a classic Tikhoff–Linberg procedure, while seven with
tumours arising from the proximal humerus were treated with a modified
Tikhoff-Linberg operation. We used a Ligament Advanced Reinforcement
System for soft-tissue reconstruction in nine patients, but not
in the other 24. The mean Musculoskeletal Tumor Society score (MSTS) was 17.6
(95% confidence interval (CI) 15.9 to 19.4); 17.6 (95% CI 15.5 to
19.6) after the classic Tikhoff–Linberg procedure and 18.1 (95%
CI 13.8 to 22.3) after the modified Tikhoff–Linberg procedure. Patients
who had undergone a LARS soft-tissue reconstruction had a mean score
of 18.6 (95% (CI) 13.9 to 22.4) compared with 17.2 (95% CI 15.5
to 19.0) for those who did not. The Tikhoff–Linberg procedure is a useful method for wide resection
of a malignant tumour of the shoulder girdle which helps to preserve
hand and elbow function. The method of soft-tissue reconstruction
has no effect on functional outcome. Cite this article:
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.
