RESUMEN
PURPOSE: The aim of this study was to evaluate and compare different surgical treatment modalities for simple bone cysts (SBC) of the humerus regarding their effectiveness and recurrence rate. METHODS: In this retrospective study, patients who received surgical treatment for previously untreated primary SBCs of the humerus were analyzed. Demographic data, cyst-specific as well as treatment-specific parameters, complications, treatment failures, and recurrence rates were collected and correlated with different treatment modalities. Observed procedures were categorized as open procedure (n=20) or osteosynthesis alone (n=3). For the open procedure group, four subgroups could be defined. RESULTS: Twenty-three patients were included. The mean age at diagnosis was 11.6 ± 2.5 years, and the mean postoperative follow-up was 3.9 ± 2.6 years (range 1.0-10.3). After surgical intervention, a total of five (21.7%) patients showed at least one recurrence. Fracture occurred in three (13.0%) cases. The incidence of treatment failure was significantly higher in the curettage, allograft, adjuvants group, with five (83.3%) of six cases showing recurrence, than in the other subgroups (≤ 25.0%) including the osteosynthesis alone group (p=.024). For the open procedure group, the failure-free survival rates were 80.0% after two years and 50.4% after five years. For the three cases treated by osteosynthesis alone, no failures were observed. CONCLUSION: Open procedures showed similar failure rates except for the subgroup using curettage, allograft, and adjuvants which showed significantly higher treatment failure. Promising results were observed in the group which received solely osteosynthesis without cyst excision or filling, as no treatment failure was observed here.

An intrauterine infection during the first trimester of pregnancy can rapidly lead to bacteremia, with severe consequences for the patient. While these infections are mainly found after a miscarriage or an abortion, the diagnosis is sometimes made while the pregnancy is still in progress. The clinical history and symptoms reported by the patient lead to the suspicion of such a complication. Treatment must be rapid and based on a broad-spectrum antibiotic regimen covering Gram-negative, Gram-positive, aerobic and anaerobic bacteria. As soon as the treatment has been initiated, uterine curettage should be performed to remove the infected material, whether or not foetal cardiac activity is present at the time of diagnosis.
Une infection intra-utérine durant le premier trimestre de la grossesse peut rapidement mener à une bactériémie et avoir des conséquences sévères pour la patiente. Alors que ces infections sont principalement retrouvées après une fausse couche ou une interruption volontaire de grossesse, le diagnostic est parfois posé alors que la grossesse est évolutive. L'histoire clinique et les symptômes rapportés par la patiente permettent de suspecter une telle complication. La prise en charge doit être rapide et repose sur un traitement antibiotique à large spectre couvrant les bactéries Gram négatif, Gram positif, les aérobies et les anaérobies. Dès le traitement instauré, un curetage utérin devra être réalisé afin d'éliminer le matériel infecté, que l'activité cardiaque fÅtale soit présente ou non au moment du diagnostic.

Total ankle arthroplasty (TAA) has become a popular management option for ankle arthritis. Periprosthetic osteolysis is one of the most common causes for reoperation in TAA. A CT scan should be done in all suspected osteolysis cases to confirm location, quantify size and aid in surgical planning. These patients are often asymptomatic with limited evidence regarding appropriate management. Smaller lesions should be monitored for progression in size. Periprosthetic cysts measuring 10-15mm in all three axes should be considered for debridment and curettage with autogenous bone grafting. The authors believe that bone grafting of large asymptomatic periprosthetic cysts could prevent implant failure.

BACKGROUND AND OBJECTIVES: This multicenter retrospective series of consecutive extra-spinal aneurysmal bone cysts aims to identify risk factors for treatment failure. METHODS: Aneurysmal bone cysts treated within seven collaborating centers with over 12-months follow-up were eligible for inclusion. Survival analyses were performed to identify variables associated with recurrence using log-rank tests and Cox proportional hazard regression. RESULTS: One hundred and fifteen (M:F 60:55) patients were included. Median age at presentation was 13 years and median follow-up was 27 months. Seventy-five patients underwent surgical curettage and 27% of these required further intervention for recurrence. Of the 30 patients who underwent biopsy with limited percutaneous curettage as initial procedure, 47% required no further treatment. Patients under 13 years (log-rank p = 0.006, HR 2.3, p = 0.011) and those treated who had limited curettage (log-rank p = 0.001, HR 2.7, p = 0.002) had a higher risk of recurrence/persistence. CONCLUSIONS: There is a high risk of recurrence following surgical treatment for aneurysmal bone cysts and this risk is higher in young patients. However, the cyst heals in a substantial number of patients who have a limited curettage at the time of biopsy.

RATIONALE: Pulmonary embolism (PE) is a common cause of cardiovascular death whose major acquired risk factors include postoperative states, pregnancy, malignancy, and age. We report a case of PE that occurred after diagnostic curettage for abnormal uterine bleeding, with a medical history of adenomyosis and hysteromyoma. PATIENT CONCERNS AND DIAGNOSES: A 31-year-old Han Chinese female was referred to our hospital with menstrual disorders, increased menstrual flow, and severe anemia. After admission, the patient was treated with a blood transfusion, iron supplementation, and erythropoietin, and diagnostic curettage was performed the following day. On the first postoperative day, the patient developed pulmonary embolism with dyspnea and fever diagnosed by CT pulmonary angiography and significantly elevated D-dimer. INTERVENTIONS AND OUTCOMES: Molecular weight heparin was administered for PE for 2 weeks, dyspnea was relieved significantly after 2 days of treatment and the uterine bleeding did not increase; and gonadotropin-releasing hormone agonists were administered for adenomyosis after 1 week of anticoagulant therapy to reduce bleeding. We followed up for 6 months, and the patient had no recurrence of thrombosis and uterine bleeding had improved. CONCLUSION: We speculate that the occurrence of pulmonary embolism was closely related to adenomyosis, hysteromyoma, and curettage in this patient. Treating the presence of both menstrual bleeding and thromboembolism is challenging, and careful management is necessary to avoid therapeutic contradictions.

INTRODUCTION: The need for curettage of atypical cartilaginous tumors (ACT) is under debate. Curretage results in defects that weaken the bone potentially leading to fractures. The purpose of this study was to retrospectively determine postoperative fracture risk after curettage of chondroid tumors, including patient-specific characteristics that could influence fracture risk. METHODS: A total of 297 adult patients who underwent curettage of an ACT followed by phenolisation and augmentation were retrospectively evaluated. Explanatory variables were, sex, age, tumor size, location, augmentation type, and plate fixation. The presence of a postoperative fracture was radiologically diagnosed. Included patients had at least 90 days of follow-up. RESULTS: A total of 183 females (62%) were included and 114 males (38%), with an overall median follow-up of 3.2 years (IQR 1.6-5.2). Mean diameter of the lesions was 4.5 (SD 2.8) cm. Patients received augmentation with allograft bone (n = 259, 87%), PMMA (n = 11, 3.7%), or did not receive augmentation (n = 27, 9.1%). Overall fracture risk was 6%. Male sex (p = 0.021) and lesion size larger than 3.8 cm (p < 0.010) were risk factors for postoperative fracture. INTERPRETATION: Curettage of ACT results in an overall fracture risk of 6%, which is increased for males with larger lesions.

PURPOSE: Polymethyl-methacrylate cement (PMMA) is often used as bone defect reconstruction material after surgical removal of giant cell tumors. The purpose of this study was to investigate if the application of PMMA improves the local recurrence rates for giant cell tumors (GCT) of appendicular bone treated with intralesional curettage. METHODS: A retrospective analysis of all appendicular GTCs treated at two major Danish sarcoma centres between the 1st of January 1998 and December 31st 2013; minimum follow-up of 3.0 years (median: 8.9; 1.3-18.7 years). Kaplan-Meier survival model, log-rank and multivariate Cox regression were used to calculate and compare local recurrence rates. p-values <0.05 were considered statistically significant. RESULTS: 102 patients (M59/F43), median age 31Y (11-84) were included in this study. The overall 3-years local recurrence-rate was 19.9% (95%CI: 11.9-27.9%); 91% had occurred within 3 years. In patients treated with intralesional curettage (n = 64), the 3-years recurrence-rate was 30.6% (95%CI: 18.8-42.4%), compared to 2.6% (95%CI: 0.0-7.8%) in patients treated with wide resection or amputation (n = 38), p < .001. The 3-years recurrence-rate for patients treated with intralesional curettage and reconstruction using PMMA was 29.0% (95%CI: 12.6-45.4%) and without PMMA: 31.8% (95%CI: 15.2-48.4%), p = .83. CONCLUSION: We found that the use of PMMA for bone defect reconstruction after intralesional curettage of GTCs in the appendicular skeleton did not ensure a reduced risk of local recurrence.

This systematic review evaluates the effects of heat treatments in de novo, residual and recurrent giant cell tumors of bone (GCTB). Studies were eligible for inclusion if one of the following treatments was administered: radiofrequency ablation (RFA), microwave ablation, argon cauterization, electrocauterization and hot liquid treatment. The primary outcome was recurrence. Secondary outcomes were complications, pain, function, and quality of life. Recurrence rates for microwave ablation as an adjuvant to intralesional curettage were 0%, 4% and 10% (3 retrospective single-group studies); for argon cauterization 4%, 8% and 26% (3 cohort studies); electrocauterization 0% to 33% (8 cohort studies); and hot liquid 9.5% and 24% (2 cohort studies). Follow-up was generally ≥24 months. Data on pain, function and quality of life were scarce. Complications included infection and secondary osteoarthritis. Current evidence does not demonstrate or exclude an effect of heat treatments on recurrence in GCTB. Further research should objectify if (subgroups of) patients benefit from these treatments.

OBJECTIVES: This study aims to investigate the effect of adjuvant cryotherapy added to well-performed high-speed burr curettage on the long-term surgical outcomes of chondroblastoma cases. PATIENTS AND METHODS: Between January 2004 and December 2020, a total of 30 chondroblastoma cases (19 males, 11 females; median age: 18.6 years; range, 9 to 53 years) who were surgically treated were retrospectively analyzed. The pressurized-spray technique was performed using liquid nitrogen. Data including age, sex, radiological appearance, treatment modality, duration of follow-up, skin problems, and recurrence were recorded. All patients received adjuvant liquid nitrogen cryotherapy after extended intralesional curettage with high-speed burr. The bone cavity was filled with an autologous iliac crest bone graft, allograft, or polymethylmethacrylate (PMMA). RESULTS: The median follow-up was 54 (range, 19 to 120) months. The lesion was located around the knee in 16 (53.3%), in the shoulder in seven (23.3%), around the hip in five (16.6%), and in the ankle in two (6.6%) cases. The defect was filled with an autologous iliac crest bone graft in 28 (93.3%), an additional allograft in eight (26.7%), and PMMA in two (6.7%) cases. Local recurrence was observed in only two (6.7%) patients during follow-up. Two (6.7%) patients developed physeal growth arrest. Osteoarthritic changes were observed in two (6.7%) patients (one knee and one hip) due to the periarticular location of the tumor. Three (10%) patients had skin complications. None of the cases had a pathological fracture. CONCLUSION: A well-performed extended intralesional curettage with high-speed burr is the first and essential step in treating chondroblastoma. Adding adjuvant liquid nitrogen cryotherapy with high-speed burr can improve treatment outcomes and significantly reduce the recurrence rate of this disease.

OBJECTIVE: Giant cell tumor of bone (GCTB) is a common primary bone tumor with latent malignant tendency. GCTB is prone to occur around the knee joint, and surgery is the major treatment method. There are relatively few reports on denosumab in the treatment of recurrent GCTB around the knee joint and postoperative function evaluation of patients. This research aimed to explore the appropriate surgical options for the treatment of recurrent GCTB around the knee joint. PATIENTS AND METHODS: 19 patients with recurrent GCTB around the knee joint, who were admitted to Hospital for 3 months following denosumab treatment from January 2016 to December 2019, were included as the research subjects. The prognosis was compared between patients treated with curettage combined with polymethylmethacrylate (PMMA) and those with extensive-resection replacement of tumor prosthesis (RTP). A deep learning model of Inception-v3 combined with a Faster region-based convolutional neural network (Faster-RCNN) was constructed to classify and identify X-ray images of patients. The Musculoskeletal Tumor Society (MSTS) score, short form-36 (SF-36) score, recurrence, and the rate of complications were also analyzed during the follow-up period. RESULTS: The results showed that the Inception-v3 model trained on the low-rank sparse loss function was obviously the best for X-ray image classification, and the classification and identification effect of the Faster-RCNN model was significantly better than that of the convolutional neural network (CNN), U-Net, and Fast region-based convolutional neural network (Fast-RCNN) models. During the follow-up period, the MSTS score in the PMMA group was significantly higher than that in the RTP group (p<0.05), while there was no significant difference in the SF-36 score, recurrence, and the rate of complications (p>0.05). CONCLUSIONS: The deep learning model could improve the classification and identification of the lesion location in the X-ray images of GCTB patients. Denosumab was an effective adjuvant for recurrent GCTB, and widely extensive-resection RTP could reduce the risk of local recurrence after denosumab treatment for recurrent GCTB.

BACKGROUND: Only 3 % of osseous tumors occur in the foot. The metatarsals are the -most common site whereas the calcaneus and talus are less common sites. Because these tumors are rare, the aim of our study is to assess the functional and the oncological outcome of patients with benign hindfoot tumors managed by curettage. METHODS: The clinical and radiological data of 41 patients diagnosed with benign hindfoot tumors were retrospectively reviewed. The study included 31 males and 10 females. The average age was 23.68 (range, 5-49) years. The average follow-up period was 92.7 (range, 12-244) months. RESULTS: At the last follow-up visit, the average Musculoskeletal Tumor Society scoring system (MSTS) score was 28.12 (range, 21-30). MSTS scores were higher in patients with latent tumors (P = .028) and patients managed by simple curettage (P = .018). The recurrence rate in calcaneal tumors was higher than those in the talus. The overall complication rate was 12.2 % (5 of 41 patients). Infection and subtalar arthritis were the most common complications. CONCLUSION: Curettage of benign bone tumors of talus or calcaneus proved to be an effective method in the management of these patients. Their functional outcome is also excellent. All the complications are manageable without long term morbidity. LEVEL OF EVIDENCE: Level IV Therapeutic study.

As a locally aggressive primary benign tumor, giant cell tumor of bone (GCTB) presents a challenge to surgeons, as it often recurs regardless of surgical resection. This report describes a case of GCTB of the distal femur in a man, aged 39 years, treated with intralesional curettage through an arthroscopic approach. A 360° view of the tumor cavity can be achieved with the help of an arthroscope, which can help complete intralesional curettage and minimize possible larger approach-related complications. The result is favorable in terms of functional outcome and recurrence after 1-year follow-up.

BACKGROUND: Suction-curettage by arthroscopic shaver is the most effective treatment for bromhidrosis; however, postoperative complications require wound management and exhibit a high risk of hypertrophic scarring. We investigated factors affecting postoperative complications. METHODS: We retrospectively evaluated data for 215 patients (430 axillae) with bromhidrosis treated with suction-curettage by arthroscopic shaver between 2011 and 2019. Cases followed for less than 1 year were excluded. Complications of hematoma or seroma, epidermis decortication, skin necrosis, and infection were recorded. Multinomial logistic analysis was used to calculate odds ratios and corresponding 95% confidence intervals for the complication of the surgery, adjusting for relevant statistically significant variables. RESULTS: Complications occurred in 52 axillae (12.1%). Epidermis decortication occurred in 24 axillae (5.6%), with a significant difference for age (P < 0.001). Hematoma occurred in 10 axillae (2.3%) with a significant difference in tumescent infiltration use (P = 0.039). Skin necrosis occurred in 16 axillae (3.7%) with a significant difference for age (P = 0.001). Infection occurred in 2 axillae (0.5%). Severe scarring occurred in 15 axillae (3.5%), with complications related to more severe skin scarring (P < 0.05). CONCLUSION: Older age was a risk factor for complications. Use of tumescent infiltration resulted in good postoperative pain control and less hematoma. Patients with complications presented with more severe skin scarring, but none experienced limited range of motion after massage.

Giant cell tumor of bone (GCTB) is most often treated with intralesional curettage; however, periarticular lesions have been shown to increase risk for osteoarthritis. Additionally, the location of these lesions may occasionally preclude a joint-sparing procedure in recurrent tumors. This study sought to investigate rates of secondary arthroplasty in long-term follow-up of knee GCTB. Cases of knee GCTB treated at our institution were reviewed. Rates of recurrence and secondary arthroplasty were recorded, and Kaplan-Meier survival analyses were performed. The records of 40 patients were reviewed. Local recurrence occurred in 25% of patients. The 1-, 5-, and 10-year recurrence-free survival (RFS) probability was 87.4% (95% CI, 77.0-97.7), 72.4% (95% CI, 57.6-87.2), and 72.4% (95% CI, 57.6-87.2), respectively. Function improved after surgery with a mean preoperative MSTS score of 14.9 (standard deviation [SD] 8.4) and mean postoperative MSTS score of 25.1 (SD 5.6) (p <0.001). Three patients had evidence of radiographic osteoarthritis at the last follow-up though they did not require arthroplasty. Arthroplasty was performed as a secondary procedure in six patients. Five patients underwent arthroplasty for recurrent tumors after initial treatment with curettage and one patient underwent patellar arthroplasty for osteoarthritis after initial treatment with an allograft composite arthroplasty. Arthroplasty is performed as a secondary procedure in patients with GCTB at a relatively infrequent rate and more often for cases of recurrent disease than for osteoarthritis. Overall, patients treated for GCTB have improved functional outcomes after surgery than before. Large, multi-institutional studies may be required to assess the incidence of secondary osteoarthritis requiring arthroplasty as this was an infrequent finding in our cohort.

OBJECTIVES: To explore the effect of cesarean scar pregnancy (CSP) treatment by comparing uterine artery chemotherapy embolization (UACE) combined with dilation and curettage (D&C) with or without ultrasound guidance. METHODS: CSP patients treated with UACE combined with D&C from January 2013 to December 2020 at Shuguang Hospital, affiliated to Shanghai University of Traditional Chinese Medicine were included in this retrospective study. The patients were divided into groups A and B according to whether D&C was guided by ultrasound. RESULTS: Forty-eight patients with CSP diagnosed by transvaginal ultrasound were included in this study, whose gestational age was <8 weeks. There were no significant differences in the basic clinical characteristics of the two groups. The success rates of the 2 groups were no significant difference, 100% (27/27) in group A and 85.7% (18/21) in group B. The maximal intraoperative blood loss of group A was 100 mL and that of group B was 150 mL. There was no uterine perforation during the operation. Ultrasound guidance can shorten the D&C operation time, reduce intraoperative bleeding during D&C, and decrease the residual rate of trophoblastic tissue after D&C. CONCLUSIONS: Ultrasound guidance can improve the safety and efficiency of UACE combined with D&C in the treatment of CSP and reduce its complications. We believe it is an optimal treatment for CSP patients who do not plan to have children in the future.

BACKGROUND: Chondrosarcoma is the second most common sarcoma of bone, accounting for about 25% of primary bone tumors. Histological grading is the single most important determinant of local recurrence and metastases, where low-grade chondrosarcoma (grade 1: atypical cartilaginous lesion) is associated with 10 years survival rate 79-100%. There has been always a debate about the need for wide resection in managing low-grade chondrosarcoma, where several reports describe successful management with intra-lesional curettage and adjuvant therapy, minimizing the need for complex reconstructive procedures and improving the expected outcomes. HYPOTHESIS: Grade 1 chondrosarcoma of the appendicular skeleton can be successfully treated through extended curettage and liquid nitrogen with favorable oncological and functional outcomes. PATIENTS AND METHODS: We retrospectively assessed 113 patients with low grade chondrosarcoma in the appendicular skeleton, who were treated by extended curettage, adjuvant therapy using liquid nitrogen, reconstruction using polymethyl methacrylate and prophylactic fixation. Patients were assessed regarding incidence of recurrence, incidence of non-oncological complications and functional outcome. RESULTS: The mean follow up period was 110 months. In three patients (2.7%), local recurrence occurred. Five point three percent of the patients got non-oncological complications that were successfully managed. The mean MSTS score was 95%, with no evidence of distant metastases or disease related mortality. CONCLUSION: Grade 1 chondrosarcoma in the appendicular skeleton can be effectively treated using extended curettage, liquid nitrogen as adjuvant and cement as filler. Prophylactic fixation is required to avoid pathological fractures. When done properly, excellent functional outcome is expected. LEVEL OF EVIDENCE: IV, Case series (retrospective comparative study).

BACKGROUND AND OBJECTIVES: Chondrosarcomas in flat bones are thought to be more aggressive in their behavior, and little is known about intralesional treatment outcomes of low-grade chondrosarcoma in these locations. We tried to find the differences between patients who had low-grade chondrosarcoma in their flat bones versus those with long bone involvement with regard to (1) disease outcome, (2) functional outcome, and (3) treatment complications. METHODS: We retrospectively reviewed 44 patients with primary low-grade chondrosarcoma who were treated with intralesional curettage and cryotherapy. The patients were divided by location of tumor, group I (flat bones, seven patients) and group II (long bones, 37 patients). RESULTS: The local recurrence rate was higher in group I with 5 years disease-free survival of 80.0% in group I and 97.0% in group II (p = 0.001). All recurrent cases were noted to have initially presented with soft tissue extension (Enneking stage IB). The mean Musculoskeletal Tumor Society score at the last follow-up was 21.7 in group I and 27.9 in group II (p = 0.045). CONCLUSIONS: Intralesional curettage and cryotherapy for low-grade chondrosarcoma appear to be a safe and reasonable surgical option for patients with lesions confined to bone (Enneking stage IA). LEVEL OF EVIDENCE: Level III, retrospective cohort study. See the Guidelines for Authors for a complete description of levels of evidence.

PURPOSE: The approach to the treatment of enchondromas of the hand is varied, and there is no clear consensus on graft source, fixation, or need for intraoperative adjuvant therapy. We reviewed a cohort of patients who underwent curettage and bone grafting with cancellous allograft chips without internal fixation or adjuvant therapy and reported on postoperative range of motion (ROM) and recurrence rates. METHODS: We performed a retrospective review of patients who underwent surgical treatment for hand enchondroma over a 23-year period. We collected information on demographics and presenting enchondroma characteristics, including Takigawa classification and presence of pathologic fracture or associated syndromes. Patients were treated with open biopsy with curettage and grafting with cancellous allograft chips. Postoperative ROM, complications, and recurrences were recorded. RESULTS: Our series included 111 enchondromas in 104 patients. Seventeen of 104 patients (16%) had a diagnosis of Ollier disease. Average length of follow-up was 3.1 years. Eighty-one percent of patients achieved full ROM. Treatment of patients who presented with preoperative pathologic fracture resulted in a greater frequency of reduced postoperative ROM at 28% (9/32) compared to 15% (11/72) of those patients who did not present with preoperative pathologic fracture. Local recurrence developed in 5 of 50 (10%) patients with a minimum of 2 years of follow-up. Local recurrence occurred at higher-than-average rates in patients with giant form Takigawa classification (43%, 3/7) and Ollier disease (23%, 3/13). CONCLUSIONS: Treatment of enchondromas with biopsy, curettage, and allograft results in full ROM in 81% of patients. Patients with preoperative pathologic fracture should be advised of a greater risk of postoperative extension deficit. Recurrence remains rare and is associated with syndromic presentation and giant form lesions. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

CASE: A 9-month-old male child presented with swelling over the distal radius that was debrided, and histopathology revealed tuberculosis. Curettage left a large bony defect in the distal radius metaphysis. The defect was not surgically addressed because near-complete spontaneous filling of the defect was seen at 3 months' follow-up. The patient was given antituberculous therapy for 12 months and had excellent outcomes at 24 months' follow-up. CONCLUSION: A large bony defect secondary to tuberculosis, in the distal radius metaphysis in an infant, regenerated spontaneously without the need for bone substitutes, bone grafting, or complex microvascular procedures.

BACKGROUND: Following curettage of giant cell tumor of bone (GCTB), it is common to fill the cavity with polymethylmethacrylate (PMMA) bone cement, bone allograft, or artificial bone to maintain bone strength; however, there is a 2-14% risk of postoperative fractures. We conducted this retrospective study to clarify the risk factors for fractures after curettage for GCTB of the extremities. METHODS: This study included 284 patients with GCTBs of the extremities who underwent curettage at our institutions between 1980 and 2018 after excluding patients whose cavities were not filled with anything or who had additional plate fixation. The tumor cavity was filled with PMMA bone cement alone (n = 124), PMMA bone cement and bone allograft (n = 81), bone allograft alone (n = 63), or hydroxyapatite graft alone (n = 16). RESULTS: Fractures after curettage occurred in 10 (3.5%) patients, and the median time from the curettage to fracture was 3.5 months (interquartile range [IQR], 1.8-8.3 months). The median postoperative follow-up period was 86.5 months (IQR, 50.3-118.8 months). On univariate analysis, patients who had GCTB of the proximal or distal femur (1-year fracture-free survival, 92.5%; 95% confidence interval [CI]: 85.8-96.2) presented a higher risk for postoperative fracture than those who had GCTB at another site (100%; p = 0.0005). Patients with a pathological fracture at presentation (1-year fracture-free survival, 88.2%; 95% CI: 63.2-97.0) presented a higher risk for postoperative fracture than those without a pathological fracture at presentation (97.8%; 95% CI: 95.1-99.0; p = 0.048). Patients who received bone grafting (1-year fracture-free survival, 99.4%; 95% CI: 95.7-99.9) had a lower risk of postoperative fracture than those who did not receive bone grafting (94.4%; 95% CI: 88.7-97.3; p = 0.003). CONCLUSIONS: For GCTBs of the femur, especially those with pathological fracture at presentation, bone grafting after curettage is recommended to reduce the risk of postoperative fracture. Additional plate fixation should be considered when curettage and cement filling without bone grafting are performed in patients with GCTB of the femur. This should be specially performed for those patients with a pathological fracture at presentation.
