Vascularized fibular epiphyseal transfer for proximal humeral reconstruction in children with a primary sarcoma of bone

Aims Preserving growth following limb-salvage surgery of the upper limb in children remains a challenge. Vascularized autografts may provide rapid biological incorporation with the potential for growth and longevity. In this study, we aimed to describe the outcomes following proximal humeral reconstruction with a vascularized fibular epiphyseal transfer in children with a primary sarcoma of bone. We also aimed to quantify the hypertrophy of the graft and the annual growth, and to determine the functional outcomes of the neoglenofibular joint. Patients and Methods We retrospectively analyzed 11 patients who underwent this procedure for a primary bone tumour of the proximal humerus between 2004 and 2015. Six had Ewing’s sarcoma and five had osteosarcoma. Their mean age at the time of surgery was five years (two to eight). The mean follow-up was 5.2 years (1 to 12.2). Results The overall survival at five and ten years was 91% (confidence interval (CI) 95% 75% to 100%). At the time of the final review, ten patients were alive. One with local recurrence and metastasis died one-year post-operatively. Complications included seven fractures, four transient nerve palsies, and two patients developed avascular necrosis of the graft. All the fractures presented within the first postoperative year and united with conservative management. One patient had two further operations for a slipped fibular epiphysis of the autograft, and a hemi-epiphysiodesis for lateral tibial physeal arrest. Hypertrophy and axial growth were evident in nine patients who did not have avascular necrosis of the graft. The mean hypertrophy index was 65% (55% to 82%), and the mean growth was 4.6 mm per annum (2.4 to 7.6) in these nine grafts. At final follow-up, the mean modified functional Musculoskeletal Tumour Society score was 77% (63% to 83%) and the mean Toronto Extremity Salvage Score (TESS) was 84% (65% to 94%). Conclusion Vascularized fibular epiphyseal transfer preserves function and growth in young children following excision of the proximal humerus for a malignant bone tumour. Function compares favourably to other limb-salvage procedures in children. Longer term analysis is required to determine if this technique proves to be durable into adulthood.

Abstract Purpose The purpose of this study was to introduce the surgical technique and functional outcome of joint-sparing limb salvage surgery with metaphyseal osteotomy by dependent design of three-dimensional printed prothesis for children with osteosarcoma in distal femur.Methods Between 2012 to 2019, we performed twelve joint sparing limb salvage surgeries (JSLSS) with metaphyseal osteotomy for the children of osteosarcoma in the distal femur with our dependent design of 3D-printed guided plate and prothesis. The clinical assessment including resection margin, limb-length discrepancy, orthopaedic complications and functional outcome would be analyzed.Results The mean operation time for JSLSS was 107.6 minutes and the average blood loss was 194.5ml with the dependent design of 3D-printed prosthesis. With the assistance of guide plate, the mean margin of the osteosarcoma from the epiphyseal plate was 1.6 cm and the mean limb-length discrepancy was 2.2 cm with maximum follow-up period of seven years (mean 45.3 months, range 12-84 months). All the patients could bend their knee through >90° flexion, achieved similar results for ROMs in 6DOF during gait compared with normal data of Chinese knees, and the mean MSTS score was 94.7 for the patients with JSLSS. One patient had a superficial infection and there was one patient of local recurrence happened during the follow-up with the necrosis rate less than 90% by preoperative chemotherapy. None aseptic loosening happened in distal femur for the patients in this group with dependent design of 3D-printed prosthesis.Conclusion Joint-sparing limb salvage surgery by metaphyseal osteotomy with the dependent design of 3D-printed prosthesis and guide plate would be a good choice for the children with osteosarcoma in distal femur.

We have investigated the role of drug-eluting stents on patency rates after treatment of focal infrapopliteal lesions in patients with intermittent claudication and critical limb ischemia. Reports indicate that drug-eluting stents reduce the risk of restenosis after percutaneous infrapopliteal artery revascularization. A Pub Med, EMBASE, Cochrane database review search of non-randomized studies investigating patency rates, target lesion revascularisation rates, limb salvage rates and mortality rates in an up to 3-year follow-up period after drug-eluting stent placement was conducted. In addition, preliminary results of randomized studies comparing drug-eluting stents with bare-metal stents and plain balloon angioplasty in treatment of focal infrapopliteal lesions were included in this review. A total of 1039 patients from 10 non-randomized and randomized studies were included. Most commonly used drug-eluting stents were sirolimus-eluting. The mean follow-up period was 12.6 (range 8 - 24). The mean 1-year primary patency rate was 86 ± 5 %. The mean target lesion revascularization rate and limb salvage rate was 9.9 ± 5 % and 96.6 %±4 %, respectively. Results from non-randomized and preliminary results from prospective, randomized trials show a significant advantage for drug-eluting stents in comparison to plain balloon angioplasty and bare-metal stents concerning target lesion patency and in parts target lesion revascularisation. No trial reveals an advantage for drug-eluting stents with regard to limb salvage and mortality.

Purpose.In all patients treated at the Centre for Bone and Soft Tissue Sarcomas of Aarhus the functional outcome is prospectively evaluated by use of the Enneking system for the functional evaluation after surgical treatment of tumours of the musculoskeletal system. This system has been accepted by the Musculoskeletal Tumour Society and the International Symposium on Limb Salvage.Patients/methods.In the present study the functional outcome after limb-salvage surgery (89 patients) and amputation (58 patients) was compared. In the limb-salvage group the treatment was surgery alone in 50% and surgery combined with either radiotherapy in 39% or chemotherapy in 11%. Inclusion criteria were: Deep seated extremity sarcomas, age >14 years, more than 1 year post-treatment follow-up time and alive at the end of the study. Median age was 49 years (range 14–88 years). Median tumour diameter was 8 cm (range 1–20 cm), median follow-up time was 4.8 years (range 1–11 years). Wilcoxon andχ2-tests were used for statistical analyses.Results.The two groups were comparable according to age, sex, size of tumour, type of tumour, location of tumour, as well as post-treatment follow-up time. The functional scores were significantly higher after limb-salvage surgery as compared to amputation, the median scores being 85 and 47, respectively (p<0.001). A similar difference was observed if the Enneking scores were subdivided into general health-related scores and extremity-related scores. No association was found between functional scores and the following factors by use of univariate analysis: size of tumour, radiation therapy, localization of tumour and surgical margin.Discussion.We conclude that this study indicates that limb-salvage surgery is associated with a better functional outcome than that observed after amputation. However, whether this also indicates a difference in quality of life needs further studies.

Aims Limb salvage for pelvic sarcomas involving the acetabulum is a major surgical challenge. There remains no consensus about what is the optimum type of reconstruction after resection of the tumour. The aim of this study was to evaluate the surgical outcomes in these patients according to the methods of periacetabular reconstruction. Methods The study involved a consecutive series of 122 patients with a periacetabular bone sarcoma who underwent limb-salvage surgery involving a custom-made prosthesis in 65 (53%), an ice-cream cone prosthesis in 21 (17%), an extracorporeal irradiated autograft in 18 (15%), and nonskeletal reconstruction in 18 (15%). Results The rates of major complications necessitating further surgery were 62%, 24%, 56%, and 17% for custom-made prostheses, ice-cream cone prostheses, irradiated autografts and nonskeletal reconstructions, respectively (p = 0.001). The ten-year cumulative incidence of failure of the reconstruction was 19%, 9%, 33%, and 0%, respectively. The major cause of failure was deep infection (11%), followed by local recurrence (6%). The mean functional Musculoskeletal Tumour Society (MSTS) scores were 59%, 74%, 64%, and 72%, respectively. The scores were significantly lower in patients with major complications than in those without complications (mean 52% (SD 20%) vs 74% (SD 19%); p < 0.001). For periacetabular resections involving the ilium, the mean score was the highest with custom-made prostheses (82% (SD 10%)) in patients without any major complication; however, nonskeletal reconstruction resulted in the highest mean scores (78% (SD 12%)) in patients who had major complications. For periacetabular resections not involving the ilium, significantly higher mean scores were obtained with ice-cream cone prostheses (79% (SD 17%); p = 0.031). Conclusion Functional outcome following periacetabular reconstruction is closely associated with the occurrence of complications requiring further surgery. For tumours treated with periacetabular and iliac resection, skeletal reconstruction may result in the best outcomes in the absence of complications, whereas nonskeletal reconstruction is a reasonable option if the risk of complications is high. For tumours requiring periacetabular resection without the ilium, reconstruction using an ice-cream cone prosthesis supported by antibiotic-laden cement is a reliable option.

Fixation Techniques

The valgus-impacted (VI) 4-part fractures are a subset of fractures of the proximal humerus with a unique anatomic configuration characterized by a relatively lower incidence of avascular necrosis after operative intervention. We systematically reviewed clinical studies assessing the benefits and harms of least possible fixation techniques (LPFT) for this unique fracture type. Such information would be potentially helpful in developing an evidence-based approach in the management of these complex injuries. We performed analytic searches of PubMed, Embase, Web of Science, Google Scholar and the Cochrane Library, restricting it to the years 1991-2014. Included studies had to describe outcomes and complications after primary osteosynthesis with any type of LPFT apart from plate-screws and intramedullary nailing. Eligibility criteria were also included English language, more than 5 cases, minimum follow up of one year and report of clinical outcome using at least one relevant score (Constant, Neer or ASES). Based on 292 database hits we identified 12 eligible studies including 190 four-part valgus impacted fractures in 188 patients. All eligible studies were case series composed of min 8 to max 45 patients per study. The gender distribution was 60% (112) female and 40% (76) male. The average age of the patients at the time of injury was 54.5 years. In 8/12 studies an open reduction was used for fracture fixation using different surgical techniques including KW, cerclage wires, cannulated screws and osteosutures. Closed reduction and percutaneous fixation was used in 4 studies. Mean follow-up time ranged from 24 to 69 months. A good functional outcome (constant score >80) was reported in 9/12 studies. The most common complication was avascular necrosis of the humeral head with an overall incidence of 11% (range, 0-26.3%). Total avascular necrosis (AVN) was found in 15/188 patients (7.9%) and was more common in percutaneous techniques and partial AVN in 6/188 (3.1%) being more common in open techniques. The overall re-operation rate was very low (3.7%). Insufficient study designs cannot provide definite treatment recommendations and quantitative data synthesis of outcome. In general, LPFT for 4-part VI fractures leads to satisfactory outcomes with low incidence of complications. A considerable risk of biases can be attributed to fracture classification, proper radiological control, mean age of patients, mixed types of fixation methods, nonage adjusted clinical scoring and small follow up periods. These factors are discussed in detail. Level of evidence: systematic review of literature (level IV) as most of the studies were level IV.

Aim: To evaluate the effect of phacoemulsification with intraocular lens implantation in eyes with pre-existing trabeculectomy.Methods: This prospective single-center clinical study evaluated intraocular pressure in 60 eyes of 60 patients who underwent phacoemulsification and implantation of a foldable intraocular lens after a previous successful trabeculectomy. Patients who had a trabeculectomy more than one year prior to the study were included. Intraocular pressure, number of antiglaucoma medications, bleb appearance, and visual acuity were recorded preoperatively, and at each follow-up examination and 12 months after phacoemulsification.Results: The mean intraocular pressure before phacoemulsification was 12.42 mmHg (SD, 4.60 mmHg), which increased to 14.98 mmHg (SD, 4.18 mmHg), 14.47 mmHg (SD, 3.58 mmHg), 15.44 mmHg (SD, 3.60 mmHg), and 15.71 mmHg (SD, 3.47 mmHg) after one, three, six, and 12 months, respectively. At each follow-up visit, the mean IOP was significantly higher than the preoperative value (p < 0.001, p = 0.015, p ≤ 0.001, and p = 0.001 at month one, three, six, and 12, respectively). The mean preoperative best-corrected visual acuity was 0.98 logMAR (SD, 0.44 logMAR) and the mean postoperative best-corrected visual acuity at 12 months was 0.20 logMAR (SD, 0.21 logMAR) [p = 0.0001]. The mean preoperative number of antiglaucoma medications used was 0.57 (SD, 0.63), which increased to 0.65 (SD, 0.63 ), 0.70 (SD, 0.72 ) 0.68, (SD, 0.70), and 0.67 (SD, 0.77 ) at one, three, six, and 12 months, respectively, but there were no statistically significant differences. Bleb size decreased clinically after phacoemulsification. Nineteen of 60 eyes (32%) developed fibrosis of bleb with decreased bleb size.Conclusion: Phacoemulsification with intraocular lens implantation significantly increased intraocular pressure and increased the number of antiglaucoma medications in eyes with pre-existing functioning filtering blebs.

Aims 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. Patients and Methods 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). Results At final follow-up, the mean Musculoskeletal Tumor Society Score of 22 evaluable patients was 94% (73 to 100). Eight major complications, five fractures (21.7%), and three nonunions (13%) were seen in seven patients (30.4%). Revision-free survival was 72.3% at five, ten, and 15 years, with fracture and nonunion needing surgery as failure endpoints. Overall survival, with removal of allograft or amputation as failure endpoints, was 94.4% at five, ten, and 15 years. Discussion There were no complications needing surgical revision after five years had elapsed from surgery, suggesting that the mechanical strength of the implant improves with time, thereby decreasing the risk of complications. In young patients with an intercalary bone tumour of the femur, combining a VFG and massive allograft may result in a reconstruction that lasts a lifetime.
