The ulna is an extremely rare location for primary bone tumours of the elbow in paediatrics. Although several reconstruction options are available, the optimal reconstruction method is still unknown due to the rarity of proximal ulna tumours. In this study, we report the outcomes of osteoarticular ulna allograft for the reconstruction of proximal ulna tumours. Medical profiles of 13 patients, who between March 2004 and November 2021 underwent osteoarticular ulna allograft reconstruction after the resection of the proximal ulna tumour, were retrospectively reviewed. The outcomes were measured clinically by the assessment of elbow range of motion (ROM), stability, and function, and radiologically by the assessment of allograft-host junction union, recurrence, and joint degeneration. The elbow function was assessed objectively by the Musculoskeletal Tumor Society (MSTS) score and subjectively by the Toronto Extremity Salvage Score (TESS) and Mayo Elbow Performance Score (MEPS) questionnaire.Aims
Methods
Surgical site infection (SSI) after soft-tissue sarcoma (STS) resection is a serious complication. The purpose of this retrospective study was to investigate the risk factors for SSI after STS resection, and to develop a nomogram that allows patient-specific risk assessment. A total of 547 patients with STS who underwent tumour resection between 2005 and 2021 were divided into a development cohort and a validation cohort. In the development cohort of 402 patients, the least absolute shrinkage and selection operator (LASSO) regression model was used to screen possible risk factors of SSI. To select risk factors and construct the prediction nomogram, multivariate logistic regression was used. The predictive power of the nomogram was evaluated by receiver operating curve (ROC) analysis in the validation cohort of 145 patients.Aims

Between June 2005 and March 2008, 14 patients with a Campanacci grade-3 giant-cell tumour of the distal radius were treated by en bloc resection and reconstruction by ulnar translocation with arthrodesis of the wrist. The mean length of radius resected was 7.9 cm (5.5 to 15). All the patients were followed to bony union and 12 were available at a mean follow-up of 26 months (10 to 49). The mean time to union was four months (3 to 7) at the ulnocarpal junction and five months (3 to 8) at the ulnoradial junction. All except one patient had an excellent range of pronation and supination. The remaining patient developed a radio-ulnar synostosis. The mean Musculoskeletal Tumor Society score was 26 (87%, range 20 to 28). Three patients had a soft-tissue recurrence, but with no bony involvement. They underwent a further excision and are currently well and free from disease. Ulnar translocation provides a local vascularised bone graft to reconstruct the defect left after excision of the distal radius for giant cell tumour. It avoids the need for a microvascular procedure while retaining rotation of the
We present a retrospective study of patients suffering from a variety of benign tumours in whom external fixators were used to treat deformity and limb-length discrepancy, and for the reconstruction of bone defects. A total of 43 limbs in 31 patients (12 male and 19 female) with a mean age of 14 years (2 to 54) were treated. The diagnosis was Ollier’s disease in 12 limbs, fibrous dysplasia in 11, osteochondroma in eight, giant cell tumour in five, osteofibrous dysplasia in five and non-ossifying fibroma in two. The lesions were treated in the tibia in 19 limbs, in the femur in 16, and in the
Aneurysmal bone cysts (ABCs) are locally aggressive lesions typically found in the long bones of children and adolescents. A variety of management strategies have been reported to be effective in the treatment of these lesions. The purpose of this review was to assess the effectiveness of current strategies for the management of primary ABCs of the long bones. A systematic review of the published literature was performed to identify all articles relating to the management of primary ABCs. Studies required a minimum 12-month follow-up and case series reporting on under ten participants were not included.Aims
Methods
The aim of this study was to assess orthopaedic oncologic patient morbidity resulting from COVID-19 related institutional delays and surgical shutdowns during the first wave of the pandemic in New York, USA. A single-centre retrospective observational study was conducted of all orthopaedic oncologic patients undergoing surgical evaluation from March to June 2020. Patients were prioritized as level 0-IV, 0 being elective and IV being emergent. Only priority levels 0 to III were included. Delay duration was measured in days and resulting morbidities were categorized into seven groups: prolonged pain/disability; unplanned preoperative radiation and/or chemotherapy; local tumour progression; increased systemic disease; missed opportunity for surgery due to progression of disease/lost to follow up; delay in diagnosis; and no morbidity.Aims

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 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
In patients with a tumour affecting the distal
ulna it is difficult to preserve the function of the wrist following extensive
local resection. We report the outcome of 12 patients (nine female,
three male) who underwent excision of the distal ulna without local
soft-tissue reconstruction. In six patients, an aggressive benign
tumour was present and six had a malignant tumour. At a mean follow-up
of 64 months (15 to 132) the mean Musculoskeletal Tumour score was
64% (40% to 93%) and the mean DASH score was 35 (10 to 80). The
radiological appearances were satisfactory in most patients. Local
recurrence occurred in one patient with benign disease and two with
malignant disease. The functional outcome was thus satisfactory
at a mean follow-up in excess of five years, with a relatively low
rate of complications. The authors conclude that complex reconstructive
soft-tissue procedures may not be needed in these patients. Cite this article:
Myxofibrosarcomas (MFSs) are malignant soft-tissue sarcomas characteristically
presenting as painless slowly growing masses in the extremities.
Locally infiltrative growth means that the risk of local recurrence
is high. We reviewed our experience to make recommendations about
resection strategies and the role of the multidisciplinary team
in the management of these tumours. Patients with a primary or recurrent MFS who were treated surgically
in our unit between 1997 and 2012 were included in the study. Clinical
records and imaging were reviewed. A total of 50 patients with a
median age of 68.4 years (interquartile range 61.6 to 81.8) were
included. There were 35 men; 49 underwent surgery in our unit.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:
We evaluated the oncological and functional outcome of 27 patients who had limb salvage for a soft-tissue sarcoma of the foot or ankle between 1992 and 2007, with a mean follow-up of 7.5 years (1.05 to 16.2). There were 12 men and 15 women, with a mean age at presentation of 47 years (12 to 84). Referrals came from other hospitals for 16 patients who had previous biopsy or unplanned excision, and 11 presented de novo. There were 18 tumours located in the foot and nine around the ankle. Synovial sarcoma was the most frequent histological diagnosis. Excision was performed in all cases, with 16 patients requiring plastic surgical reconstruction with 13 free and three local flaps. Adjuvant treatment was undertaken in 20 patients, 18 with radiotherapy and two by chemotherapy. Limb salvage was successful in 26 of the 27 patients. There have been two local recurrences and two mesenchymal metastases. Four patients have died of their sarcoma and two of other causes. Function was evaluated with the Toronto Extremity Salvage Score and a mean overall score of 89.40 (52.1 to 100) was obtained. A questionnaire revealed that all surviving patients are able to wear normal shoes and none require a walking aid. Limb salvage can achieve good oncological and functional results with additional treatment.
We have reviewed five adult patients treated with endoprosthetic reconstruction of the proximal radius following resection of non-traumatic lesions. The patients had a mean age of 33.4 years (20 to 60) at the time of surgery and the mean follow-up was 7.6 years (0.8 to 16). Following surgery, all elbows were clinically stable and there was 100% survivorship of the prosthesis. Evaluation of function was assessed clinically and by the Mayo Elbow Performance Score, achieving a mean of 86% (70 to 100). Results at medium-term follow-up are encouraging with regards to elbow stability, implant survivorship and functional outcome.
The aim of this study was to determine whether
the high-sensitivity modified Glasgow prognostic score (Hs-mGPS) could
predict the disease-specific survival and oncological outcome in
adult patients with non-metastatic soft-tissue sarcoma before treatment.
A total of 139 patients treated between 2001 and 2012 were retrospectively reviewed.
The Hs-mGPS varied between 0 and 2. Patients with a score of 2 had
a poorer disease-specific survival than patients with a score of
0 (p <
0.001). The estimated five-year rate of disease-specific
survival for those with a score of 2 was 0%, compared with 85.4%
(95% CI 77.3 to 93.5) for those with a score of 0. Those with a
score of 2 also had a poorer disease-specific survival than those
with a score of 1 (75.3%, 95% CI 55.8 to 94.8; p <
0.001). Patients
with a score of 2 also had a poorer event-free rate than those with
a score of 0 (p <
0.001). Those with a score of 2 also had a
poorer event-free survival than did those with a score of 1 (p =
0.03). A multivariate analysis showed that the Hs-mGPS remained
an independent predictor of survival and recurrence. The Hs-mGPS
could be a useful prognostic marker in patients with a soft-tissue
sarcoma. Cite this article:
Several techniques have been described to reconstruct a mobile wrist joint after resection of the distal radius for tumour. We reviewed our experience of using an osteo-articular allograft to do this in 17 patients with a mean follow-up of 58.9 months (28 to 119). The mean range of movement at the wrist was 56° flexion, 58° extension, 84° supination and 80° pronation. The mean ISOLS-MSTS score was 86% (63% to 97%) and the mean patient-rated wrist evaluation score was 16.5 (3 to 34). There was no local recurrence or distant metastases. The procedure failed in one patient with a fracture of the graft and an arthrodesis was finally required. Union was achieved at the host-graft interface in all except two cases. No patient reported more than modest non-disabling pain and six reported no pain at all. Radiographs showed early degenerative changes at the radiocarpal joint in every patient. A functional pain-free wrist can be restored with an osteo-articular allograft after resection of the distal radius for bone tumour, thereby avoiding the donor site morbidity associated with an autograft. These results may deteriorate with time.
Rarely, the extent of a malignant bone tumour
may necessitate resection of the complete humerus to achieve adequate
oncological clearance. We present our experience with reconstruction
in such cases using a total humeral endoprosthesis (THER) in 20
patients (12 male and eight female) with a mean age of 22 years
(6 to 59). We assessed the complications, the oncological and functional
outcomes and implant survival. Surgery was performed between June
2001 and October 2009. The diagnosis included osteosarcoma in nine,
Ewing’s sarcoma in eight and chondrosarcoma in three. One patient
was lost to follow-up. The mean follow-up was 41 months (10 to 120)
for all patients and 56 months (25 to 120) in survivors. There were
five local recurrences (26.3%) and 11 patients were alive at time
of last follow-up, with overall survival for all patients being
52% (95% confidence interval (CI) 23.8 to 74) at five years. The
mean Musculoskeletal Tumor Society score for the survivors was 22
(73%; 16 to 23). The implant survival was 95% (95% CI 69.5 to 99.3)
at five years. The use of a THER in the treatment of malignant tumours of bone
is oncologically safe; it gives consistent and predictable results
with low rates of complication.
Giant cell tumours (GCTs) of the small bones
of the hands and feet are rare. Small case series have been published but
there is no consensus about ideal treatment. We performed a systematic
review, initially screening 775 titles, and included 12 papers comprising
91 patients with GCT of the small bones of the hands and feet. The
rate of recurrence across these publications was found to be 72%
(18 of 25) in those treated with isolated curettage, 13% (2 of 15)
in those treated with curettage plus adjuvants, 15% (6 of 41) in
those treated by resection and 10% (1 of 10) in those treated by
amputation. We then retrospectively analysed 30 patients treated for GCT
of the small bones of the hands and feet between 1987 and 2010 in
five specialised centres. The primary treatment was curettage in
six, curettage with adjuvants (phenol or liquid nitrogen with or
without polymethylmethacrylate (PMMA)) in 18 and resection in six.
We evaluated the rate of complications and recurrence as well as
the factors that influenced their functional outcome. At a mean follow-up of 7.9 years (2 to 26) the rate of recurrence
was 50% (n = 3) in those patients treated with isolated curettage,
22% (n = 4) in those treated with curettage plus adjuvants and 17%
(n = 1) in those treated with resection (p = 0.404). The only complication
was pain in one patient, which resolved after surgical removal of remnants
of PMMA. We could not identify any individual factors associated
with a higher rate of complications or recurrence. The mean post-operative
Musculoskeletal Tumor Society scores were slightly higher after
intra-lesional treatment including isolated curettage and curettage
plus adjuvants (29 (20 to 30)) compared with resection (25 (15 to
30)) (p = 0.091). Repeated curettage with adjuvants eventually resulted
in the cure for all patients and is therefore a reasonable treatment
for both primary and recurrent GCT of the small bones of the hands
and feet. Cite this article:
We evaluated the construct validity of the Musculoskeletal Tumour Society rating scale (Enneking score) as a functional measure for patients with sarcoma involving the upper limb. We compared the Enneking score by examining the correlation between two patient-derived outcome measures, the Disability of the Arm, Shoulder, and Hand (DASH) questionnaire and the Medical Outcomes Study Short Form-36 (SF-36) as indicators of functional status in 40 patients with malignant or aggressive benign bone and soft-tissue tumours of the upper limb who had undergone surgical treatment. The frequency distributions were similar among the three scoring systems. As for the validity, Spearman’s rank correlation coefficient of the Enneking score to the DASH questionnaire was −0.79 and that of the Enneking to the SF-36 subscales ranged from 0.38 to 0.60. Despite being a measure from the surgeon’s perspective, the Enneking score was shown to be a valid indicator of physical disability in patients with malignant or aggressive benign tumours of the upper limb and reflected their opinion.
In our database of 7935 patients referred for investigation of a soft-tissue mass, only 100 were found to have a soft-tissue metastasis (1.3%). Our aim was to define the clinical features of such patients and to identify the site of their primary tumour. The most common presentation was a painful lump, deep to the fascia, ranging between 2 cm and 35 cm (mean 8.3 cm) with 78% of the lumps located deep to the fascia. The mean age of the patients at presentation was 64 years (22 to 84) and there were almost equal numbers of men and women. Of 53 patients with a history of malignancy, 52 had metastases from the same primary (lung in 12, melanoma in ten, kidney in nine, gastrointestinal track in four, breast in five, bladder in four, and others in eight). The other 47 had no history of malignancy and the metastasis was the first presentation. The primary sites in these cases were the lung in 19, gastro-intestinal track in four, kidney in two, melanoma in nine, other in three, and unknown (despite investigations) in ten. There was no correlation between the site of the metastases and the primary tumour. Of the 7935 patients, 516 had a history of malignancy. Of these, only 10% had a soft-tissue metastasis, 29% had a benign diagnosis, 55% a soft-tissue sarcoma and 6% another malignancy. Patients with soft-tissue metastases have similar clinical features to those with soft-tissue sarcomas and should be considered for assessment at appropriate diagnostic centres for patients with suspicious soft-tissue lumps.
We describe a consecutive series of five patients with bone or soft-tissue sarcomas of the elbow and intra-articular extension treated by complex soft tissue, allograft bone and prosthetic joint replacement after wide extra-articular
