- Abstract
Introduction: Previous studies have highlighted the association between insurance status and poor outcomes after surgical treatment of sarcomas in the United States.1-3 It is unclear how much of this disparity is mediated by confounding factors such as medical comorbidities and socioeconomic status and how much can be explained by barriers to care caused by insurance status., Methods: Surveillance, Epidemiology, and End Results-Medicare linkage data were procured for 7,056 patients undergoing treatment for bone and soft-tissue sarcomas in the extremities diagnosed between 2006 and 2013. A Cox proportional hazards model was used to assess the relative contributions of insurance status, medical comorbidities, tumor factors, treatment characteristics, and other demographic factors (race, household income, education level, and urban/rural status) to overall survival., Results: Patients with Medicaid insurance had a 28% higher mortality rate over the period studied, compared with patients with private insurance (hazard ratio, 1.28; 95% confidence interval, 1.03 to 1.60, P = 0.026), even when accounting for all other confounding variables. The 28% higher mortality rate associated with having Medicaid insurance was equivalent to being approximately 10 years older at the time of diagnosis or having a Charlson comorbidity index of 4 rather than zero (hazard ratio, 1.27)., Discussion: Insurance status is an independent predictor of mortality from sarcoma, with 28% higher mortality in those with pre-expansion Medicaid.4,5 This association between insurance status and higher mortality held true even when accounting for numerous other confounding factors. Additional study is necessary into the mechanism for this healthcare disparity for the uninsured and underinsured, as well as strategies to resolve this inequality., (Copyright © 2022 by the American Academy of Orthopaedic Surgeons.)

- Abstract
Background: A giant cell tumor is a benign locally aggressive tumor commonly seen in the distal radius with reported recurrence rates higher than tumors at other sites. The dilemma for the treating surgeon is deciding whether intralesional treatment is adequate compared with resection of the primary tumor for oncologic and functional outcomes. More information would be helpful to guide shared decision-making., Questions/purposes: We asked: (1) How will validated functional scores, ROM, and strength differ between resection versus intralesional excision for a giant cell tumor of the distal radius? (2) How will recurrence rate and reoperation differ between these types of treatments? (3) What are the complications resulting in reoperation after intralesional excision and resection procedures? (4) Is there a difference in functional outcome in treating a primary versus recurrent giant cell tumor with a resection arthrodesis?, Methods: Between 1985 and 2008, 39 patients (39 wrists) were treated for primary giant cell tumor of the distal radius at two academic centers. Twenty patients underwent primary intralesional excision, typically in cases where bony architecture and cortical thickness were preserved, 15 underwent resection with radiocarpal arthrodesis, and four had resection with osteoarticular allograft. Resection regardless of reconstruction type was favored in cases with marked cortical expansion. A specific evaluation for purposes of the study with radiographs, ROM, grip strength, and pain and functional scores was performed at a minimum of 1 year for 21 patients (54%) and an additional 11 patients (28%) were available only by phone. We also assessed reoperations for recurrence and other complications via chart review., Results: With the numbers available, there were no differences in pain or functional scores or grip strength between groups; however, there was greater supination in the intralesional excision group (p=0.037). Tumors recurred in six of 17 wrists after intralesional excision and none of the 15 after en bloc resection (p=0.030). There was no relationship between tumor grade and recurrence. There were 12 reoperations in eight of 17 patients in the intralesional excision group but only one of 11 patients (p=0.049) who underwent resection arthrodesis with distal radius allograft had a reoperation. There were no differences in functional scores whether resection arthrodesis was performed as the primary procedure or to treat recurrence after intralesional excision., Conclusions: Resection for giant cell tumor of the distal radius with distal radius allograft arthrodesis showed a lower recurrence rate, lower reoperation rate, and no apparent differences in functional outcome compared with joint salvage with intralesional excision. Because an arthrodesis for recurrence after intralesional procedures seems to function well, we believe that intralesional excision is reasonable to consider for initial treatment, but the patient should be informed about the relative benefits and risks of both options during the shared decision-making process. Because arthrodesis after recurrence functions similar to the initial resection and arthrodesis, an initial treatment with curettage remains a viable, and likely the standard, mode of treatment for most giant cell tumors of the distal radius unless there is extensive bone loss., Level of Evidence: Level III, therapeutic study.

- Abstract
Background: Complications are frequent with osteoarticular allografts, and their long-term survivorship in the distal femur is unclear. Thus, the benefits of osteoarticular allografting remain controversial., Questions/purposes: We therefore determined the frequency of complications in osteoarticular allografts of the distal femur relative to their potential long-term survival., Methods: We retrospectively reviewed 26 patients who had osteoarticular allograft reconstruction of the distal femur after resection of a malignant or aggressive benign tumor of bone. The minimum followup was 15 months (average, 156 months; range, 15-283 months) for all patients and 98 months (average, 191 months; range, 98-283 months) for the surviving patients., Results: At last followup, 16 of the 26 original allografts were still in place. The overall 5-year and 10-year allograft survival rates were 69% and 63%, respectively. The 5-year and 10-year survival rates of the joint surface were 79% and 65%, respectively. Eleven patients retained their original osteoarticular allograft without a resurfacing procedure, and nine had been converted to allograft-prosthetic composites. Five patients were converted to megaprostheses and one had an amputation for local recurrence. At last followup, 25 of 26 patients retained a functional limb., Conclusions: Osteoarticular allograft reconstructions of the distal femur can provide long term survival and restore function but the risk of complications and their physical and monetary costs for patients are not trivial. Lacking the benefit of improved soft tissue attachments inherent in other anatomic sites, we believe this option is most appropriate for restoring bone stock in young patients with expectations of long-term survival.

- Abstract
The optimal treatment of giant cell tumors of the pelvis and sacrum is controversial. Our current patient series was combined with cases identified in a review of the literature published in the past 50 years, yielding a combined group of 239 lesions for study. Recurrence rates were 49% for patients who had radiation therapy alone, 47% for patients who had surgery with intralesional margins, 46% for patients who had surgery with intralesional margins and radiation therapy, and 0% for patients who had surgery with wide margins. Six percent of patients had benign lung metastases develop, 2% of patients had secondary malignancies, 2% of patients died in the perioperative period, and less than 1% of patients had multicentricity. Radiation-induced sarcoma developed in 11% of patients who received radiation for primary or recurrent lesions. Larger doses of radiation therapy did not decrease the rate of local recurrence. Recurrence after surgery and radiation was not lower than after either treatment alone. Local recurrence was more likely in the patients with sacral tumors (48%) than in the patients with pelvic tumors (34%). Disease status was worse in the patients with sacral lesions (23% died of disease) than in the patients with pelvic lesions (6% died of disease).

- Abstract
We analyzed chondrosarcomas of bone to assess whether Grade 2 tumors are more appropriately grouped with Grade 1 chondrosarcomas or Grade 3 and dedifferentiated chondrosarcomas (Musculoskeletal Tumor Society Stage I or Stage II). A retrospective chart review identified 109 patients who presented with nonmetastatic chondrosarcoma. Data were gathered on each tumor's histologic grade, extent (intracompartmental versus extracompartmental), resection margin status, and site (axial versus appendicular). The cohort included 60 males and 49 females with a mean age of 50 years. Forty tumors were located in the axial skeleton and the remainder were distributed throughout the appendicular skeleton. Fifty-three tumors were Grade 1, 40 tumors were Grade 2, eight tumors were Grade 3, and eight tumors were dedifferentiated. Statistical analysis established grade as the only significant variable for this group of patients; extracompartmental tumor spread also correlated with outcome, but not independent of the grade. Margin status and site were not statistically significant with respect to outcome. Chi-square analysis also established that Grade 2 tumors are grouped more appropriately with the Grade 1 chondrosarcomas as Musculoskeletal Tumor Society Stage I neoplasms. These data should be considered when developing the surgical plan, particularly for patients with Grade 2 appendicular chondrosarcomas.

- Abstract
For giant cell tumors of bone, does radiotherapy provide a safe and effective treatment? This retrospective review includes 24 patients with 26 histologically diagnosed tumors treated with megavoltage radiotherapy between March 1972 and July 1996. Of the 10 recurrent tumors, five had an intralesional resection, two had a biopsy, and three had no biopsy before radiotherapy. Of the 16 previously untreated tumors, one was irradiated after a marginal resection, five after an intracapsular resection, and 10 after biopsy alone. The total doses ranged from 35 to 55 Gy (median, 43 Gy) in fractions of 1.67 to 2.33 Gy per day. Twenty of 26 tumors (77%) were controlled locally. All of the local recurrences occurred within the irradiated field. Five of six patients with local recurrence were treated successfully with additional surgery. Salvage surgery after local recurrence required amputation of an extremity in three patients and a total knee replacement in one patient. The ultimate local control rate was 96% with one patient alive with progressive disease. Lung metastases in one patient were treated successfully with surgery, chemotherapy, and radiotherapy. In one patient a radiation-induced sarcoma developed 22 years after treatment. The authors conclude that radiation therapy is a safe and effective treatment option for benign giant cell tumors of bone. A total dose greater than 40 Gy is the only variable found to significantly influence local control.

- Abstract
The results of treatment of 28 patients with Stage IE primary lymphoma of bone were evaluated. Nine patients were treated with curative intent with irradiation alone and 19 patients received radiotherapy combined with adjuvant chemotherapy. Local control was 100%. The 10-year freedom-from-relapse rate was 53%; all relapses were distant metastases, and the median time to failure was 1 year. All patients with relapses succumbed to their disease. The 10-year cause-specific survival rate was 48%. The 10-year survival rate was 53%. Multivariate analysis of survival suggested that pathologic fracture before treatment, age greater than 60 years, no aggressive chemotherapy, and lesions that were not in long bones may influence these end points. Two patients (7%) sustained moderate or severe late toxicity. Although the likelihood of local control after treatment of Stage IE primary lymphoma of bone is very high with radiotherapy, more effective systemic regimens are needed. A significant proportion of patients with this disease die of distant metastases, despite the use of what are considered standard doxorubicin-based chemotherapy regimens.

- Abstract
Three patients initially diagnosed with benign giant cell tumors of bone who had lung metastases develop were treated with whole-lung radiotherapy as part of the therapeutic treatment of their distant disease. External beam therapy to 16 Gy in 10 fractions was delivered to the whole lung, with a boost of 35 to 45 Gy to sites of gross metastatic disease. One patient's lung metastases progressed after treatment, and the patient soon died. The two other patients were long-term survivors (7.5 years and 13 years) with complete resolution of detectable disease. One of the two patients required two additional courses of local radiation to metastatic sites. The authors therefore recommend whole lung radiotherapy to 16 Gy with an additional boost to 35 to 45 Gy to gross disease as an option for patients with pulmonary metastases who are poor surgical candidates, who refuse thoracic surgery, whose disease is technically unresectable, or whose disease recurs or progresses after surgery or chemotherapy.

- Abstract
The goal of the current study was to analyze the oncologic results and wound complications in patients with soft tissue sarcomas treated with preoperative radiation therapy and en bloc resection. A standard protocol of preoperative radiotherapy was administered followed by en bloc resection in 209 patients. The protocol included needle or incisional biopsy, prospective staging, a consistent dose of radiotherapy, standardized prospective evaluation of surgical margins, and long-term followup. The target radiotherapy dose was 50.4 cGy. Twenty-nine patients had low-grade lesions, and 180 had high-grade lesions. The mean followup was 55 months. The significant wound complication rate was 22% (moderate 14%, major 7%, and amputation 1%). Wound complications were significantly higher in patients with lower extremity lesions when compared with patients with upper extremity or axial lesions, and in patients with lesions larger than 5 cm. The local recurrence rate was 11% in patients who did not have prior surgery, and 37% in patients who had prior surgery at an outside institution (17% overall). Local recurrence was increased significantly in patients who had prior surgery. At latest followup, 78 patients (47%) were continuously disease-free, six (4%) were alive with no evidence of disease, nine (5%) were alive with disease, 63 (38%) died of disease, and 11 (7%) died of another cause. The 2- and 5-year disease-specific survival rates were 77% and 67%, respectively. Overall survival was 56%. A significant decrease in survival was seen in patients who had a local recurrence, and in patients with high-grade lesions. Preoperative radiotherapy can be given safely with a wound complication rate not significantly higher than that reported for other forms of radiotherapy delivery. Local recurrence tends to be higher if surgical intervention is done before tertiary center referral. Distant disease continues to be the cause of the high mortality in these patients.

- Abstract
One hundred eight patients with low-grade soft tissue sarcoma treated at the authors' institution from 1984 to 1999 were reviewed retrospectively. Low-grade sarcomas were defined as those designated as Grade I of III or Grade I or II of IV. Patients who presented with recurrent tumors or who had multiple procedures at outside institutions were excluded. The patient's gender, age at diagnosis, histologic diagnosis, site and depth of primary involvement, and specimen size at resection were noted. Involvement of periosteum, bone, and neurovascular structures also was recorded. The decision to use radiation therapy was made case-by-case. Indications for preoperative radiation therapy included tumor adjacent to the neurovascular bundle or bone where a marginal surgical margin was anticipated. Indications for postoperative radiation therapy included followup resection of an unsuspected malignancy. Patients were evaluated according to treatment rendered. Sixty-six patients were treated with surgery alone, whereas 42 patients had excision of the tumor in conjunction with radiation therapy. The overall local control rate was 97.2% (105 of 108). There were no statistically significant differences in local recurrence, wound complication, fibrosis, or survival between the two groups. Patients treated with radiation therapy had an increased incidence of postoperative lymphedema. Kaplan-Meier 10-year survival rates were approximately 90% for both groups.

- Abstract
The current study was done to assess the oncologic outcomes after inadvertent intraoperative contamination in the treatment of musculoskeletal sarcomas, to determine the prognostic significance of these events. Forty-three patients with malignant lesions and either positive margins or intraoperative tumor penetration are included in the study. There were 12 bone lesions and 31 soft tissue lesions. The final margin was intracapsular in 11 patients, contaminated marginal in 13 patients, and contaminated wide in 19 patients. Thirty-two patients received radiation therapy with doses from 4560 to 7000 cGy. The mean followup was 69 months (range, 24-179 months). In patients in whom the surgical margin was contaminated, additional tissue was removed with the goal being to obtain tumor-free surgical margins. Local recurrence occurred in four of 32 patients (12.5%) with no gross residual tumor. There was a significant difference in the recurrence rate between a wide (0 of 19) versus a marginal or intracapsular margin (nine of 24) based on the final surgical margin. High-grade lesions were more likely to recur than low-grade lesions, and soft tissue lesions were more likely to recur than bone lesions. Similar to previous reports, treatment of inadvertent contamination with reexcision and irrigation of the wound results in a similar recurrence rate to cases without contamination. Efforts should be made to achieve a wide final margin. Adjuvant therapies should be used whenever feasible.

- Abstract
Since 1969, 144 patients with previously untreated Ewing's sarcoma of bone were entered in prospective protocols at the University of Florida. From 1969 through 1981, three institutional protocols were used, and some patients were entered into the First Intergroup Ewing's Sarcoma Study. Starting in 1982, an attempt was made to intensify treatment, with patients divided according to their primary tumor size into standard-risk (< or = 8 cm in maximum diameter) and high-risk groups. Patients with metastases at diagnosis also were considered high risk. The standard-risk protocols (Number 1 and Number 2 specified treatment with chemotherapy considered to be standard for the era; the patients who were high risk had standard chemotherapy followed by end-intensification. Treatment for patients with metastases at diagnosis was intensified additionally in 1993 with a protocol (high-risk protocol Number 5) specifically designed just for these patients. The absolute survival rate of all patients treated before 1982 was 50% at 5 years for patients without metastases at diagnosis and 18% for patients with metastases. Patients with small primary lesions had a better survival rate than patients with large primary lesions. After 1982, the 5-year survival rate for patients treated on the standard-risk protocols was 53% (1985-1998), whereas for high-risk protocols the 5-year survival rate was 63%. Survival rates were better for younger patients at diagnosis and for patients who responded well to induction chemotherapy, indicating that future trials may need to tailor therapy based on the response to induction chemotherapy.

- Abstract
Although continuous infusion of local anesthetic through nerve sheath catheters provides excellent pain control after amputation, the influence of this technique on the incidence of phantom limb pain is controversial. The current retrospective study examined the influence of continuous nerve sheath catheter analgesia and primary anesthetic technique (general or regional anesthesia) on the incidence of phantom limb pain. After institutional review board approval, data were gathered on patients who had amputation from 1990 to 1999. Medical records were reviewed to determine the level of and indication for amputation, age at time of amputation, current disease status, date of diagnosis and surgery, and primary anesthetic technique. Six months after amputation, preoperative pain, phantom limb sensations, and phantom limb pain were assessed using a verbal scale ranging from 0 (no pain) to 10 (worst pain) and methods of pain control also were evaluated. Thirty-nine patients completed the study. The incidence of phantom limb pain (visual analog scale score > or = 3) was 67% and was lower than the historic incidence (80%) before the use of this analgesia technique. Incidence of phantom limb pain was higher for patients requiring proximal versus distal amputations. The primary anesthetic technique (general versus regional) did not affect the incidence of phantom limb pain. Long-term followup showed that the incidence of phantom limb pain in patients receiving continuous nerve sheath catheter infusion is lower than previously reported for patients who had amputation for oncologic indications.

- Abstract
Twenty pathologic fractures occurred in 285 patients with soft tissue tumors that were treated with radiation therapy and surgery. Twelve of these fractures occurred in 11 patients from a subpopulation of 163 patients with 168 soft tissue tumors of the thigh (155 soft tissue sarcomas and 13 aggressive fibromatosis). The fractures occurred at a mean of 40.5 months after treatment and were not associated with significant trauma. Risk factors associated with the development of fracture included tumor location within the anterior compartment of the thigh, extensive surgical periosteal stripping, and a marginal or intralesional margin of resection. The dose, timing, and fractionation of radiation therapy were not related to the risk of fracture. A high rate of complications was seen with this series, including fracture nonunion (45%) and deep infection (20%). Prophylactic intramedullary fixation of the femur should be considered for patients undergoing resection of large tumors in the anterior compartment of the thigh requiring extensive periosteal stripping and adjuvant radiation therapy.

- Abstract
Vascular reconstruction and limb salvage surgery has been the authors' preferred approach when malignancy involves major vessels of the extremities. Treatment of 16 patients involved resection, with vascular grafting in 14 patients and rotationplasty in two patients. The major vessels were surrounded by tumor in six patients, nearly encased in three patients, invaded by tumor in four patients, and widely contaminated by intralesional surgery in three patients. The tumor stage included one Stage IB, 12 Stage IIB, two Stage IIIB sarcomas, and one multiply recurrent carcinoma. The largest average tumor dimension was 9.5 cm, and the length of grafting was 14 cm. Major nerves were sacrificed in eight (50%) patients, flaps or muscle transfers were done in seven (44%), chemotherapy was administered in nine (56%), radiation therapy was used in four (25%), and pulmonary metastasectomy was done in two (12%). At a mean followup of 56 months, 50% (eight of 16) of patients were alive without disease. Local recurrence was 12% (two of 16 patients), and infection was 12% (two of 16 patients). Limb salvage was achieved in 88% (14 of 16 patients), and functional status was judged good or excellent in 81% (13 of 16 patients). The complication rate observed in this subset of patients is significant, yet local control and the incidence of major complications was acceptable. Results observed from this series and data gathered from the literature clearly indicate that patients can avoid amputation, despite malignant involvement of major vessels to their extremities.

- Abstract
Two cases are presented in which an allograft was inserted to salvage a previous allograft bone reconstruction that had followed resection for osteosarcoma. In each instance an allograft-allograft junction was created and, with time, healed. In the first case, a fracture of a distal femoral osteoarticular allograft was salvaged by adding a second allograft and a total knee arthroplasty. This construct preserved the majority of the allograft and allowed rapid rehabilitation. In the second case, an allograft arthrodesis of the knee was salvaged after fracture by replacing the distal portion of the fractured allograft with a new allograft. Again, an allograft-allograft junction was created and healed within 6 months. Allograft fractures pose challenging reconstructive problems. In these two cases, the addition of more allograft facilitated continued limb salvage and function.

- Abstract
Osteoid osteoma is a benign bone tumor. Patients usually require surgical treatment for reliable pain relief. Difficulties with intraoperative localization of the tumor and anatomic locations that carry a high morbidity with en bloc resection complicate open surgery. Various methods have been developed to lessen the invasiveness of surgery including computed tomography-guided percutaneous radiofrequency thermal ablation. Eleven patients in three different centers were evaluated and diagnosed with osteoid osteoma based on typical histories, physical examinations, and imaging studies. All patients were treated with computed tomography-guided percutaneous radiofrequency thermal ablation after medical treatment failed. Excellent pain relief was reported in 10 patients. One patient suffered recurrence of a femoral neck lesion despite an initial 7-month period without pain. Patients were given a questionnaire to quantify the effectiveness of percutaneous radiofrequency ablation in terms of pain relief and return to function. The current study shows that percutaneous radiofrequency thermal ablation provides reliable, excellent pain relief and early return to function with minimal morbidity as compared with traditional open techniques. The authors suggest that this technique be used for all patients with extraspinal osteoid osteomas that are not immediately adjacent to neurovascular structures.

- Abstract
Intraoperative evaluation of bone marrow margins by frozen section analysis is a common practice in the surgical treatment of osteogenic sarcoma. The purpose of this study was to assess the clinical use of intraoperative marrow margin evaluation to rule out occult intramedullary tumor extension in osteosarcoma surgery. One hundred twenty-eight consecutive patients with high grade osteosarcoma diagnosed between 1988 and 1996 (Group 1) were reviewed retrospectively and compared with 92 consecutive patients treated from 1979 to 1984 (Group 2). Eighty-five patients in Group 1 met the inclusion criteria of having high grade intramedullary lesions of the long bones observed on preoperative magnetic resonance imaging evaluation of the lesion and intraoperative frozen section analysis of the bone marrow margin. Thirty-three patients in Group 2 met the same inclusion criteria with the exception of having preoperative magnetic resonance imaging. Ninety-two marrow margins in Group 1 and 33 marrow margins in Group 2 were evaluated by frozen section. All 92 marrow margins in patients in Group 1 were negative by frozen section analysis and permanent histologic analysis. Of the 33 marrow margins in patients in Group 2, three (9.1%) were reported positive for tumor. Of these, one was found to be a false positive result on permanent pathologic examination. In addition, one false negative frozen section result was found, which was positive for tumor on permanent pathologic examination. The difference in true positive results of marrow margins between Group 1 and Group 2 was statistically significant. Intraoperative marrow margin evaluation by frozen section is not mandatory with modern imaging techniques. Preoperative evaluation of tumor extent using magnetic resonance imaging and intraoperative evaluation of the specimen by the pathologist (done by bivalving the specimen) are reliable methods to ensure adequate surgical margins in most cases of conventional osteosarcoma of the long bones.

- Abstract
Arthrodesis of the knee may be indicated for the reconstruction after resection of tumor around the knee. Since the introduction of this technique, resection arthrodesis using segmental autogenous grafts has been the principal method of reconstruction. From August 1967 to February 1985, 73 patients underwent resection arthrodesis using autogenous grafts. All procedures were performed for malignant or potentially malignant lesions. Ten-year followup was available on 40 patients. The reconstructive procedure was performed using an intramedullary rod and hemicortical femoral or tibial grafts with a single autogenous nonvascularized fibula or with dual nonvascularized fibulae. Despite a high surgical complication rate, the majority of patients achieved successful limb salvage. Independent ambulation was achieved by 86% of the patients. A Musculoskeletal Tumor Society functional evaluation in 32 available patients at a mean of 17 years showed the majority of patients functioning satisfactorily. Long-term followup of these patients shows continued durability of the reconstruction and a persistent high level of function and patient satisfaction. Resection arthrodesis using massive autogenous grafts should continue to be in the armamentarium of the orthopaedic oncologist.

- Abstract
A technique of computed tomography with intravenous contrast has proven useful in the differentiation between osteoid osteoma and other similar appearing lucent lesions of bone in 6 cases. The clinical evaluation of benign appearing radiolucent lesions of long bones has been greatly improved by the use of modern imaging techniques. The differential diagnosis often is narrowed to osteoid osteoma and osteomyelitis based on plain radiographs, computed tomography, or magnetic resonance imaging. The enhancement of the lucent center of the lesion was plotted against time. The rapid uptake of contrast medium by the osteoid osteoma was in sharp contrast to the much slower enhancement in osteomyelitis. The establishment of a preoperative diagnosis enabled the surgeon to excise the lesion without a biopsy. Histologic review verified the preoperative diagnosis in all cases.

- Abstract
A review of 33 patients who underwent proximal femoral resection for primary bone tumor and reconstruction with an allograft-prosthesis composite or a megaprosthesis is presented to consider the relative merits of the 2 procedures. Clinical function, reconstruction survival, and associated complications were analyzed. Eighteen composites in 16 patients and 18 megaprosthesis in 17 patients were analyzed. Infection in the composite group and instability in the megaprosthesis group were the common causes of failure and removal of reconstructions. The average functional evaluation in 14 surviving patients with composites was 87% of normal. In 10 surviving patients with megaprostheses, the average function was 80% when complications were avoided. Survival analysis of the patients with reconstructions showed a 10 year survival of 76% for the patients with composites and 58% for those with megaprostheses. Both composite and megaprosthetic reconstruction of the proximal femur seem to function equally well from the perspective of function and survival because no statistically significant difference could be shown by this review.

- Abstract
Giant cell tumor of bone accounts for 4% to 5% of primary bone tumors in the United States. Multicentric giant cell tumors occur in < 1% of all patients with giant cell tumors, and only 43 patients with multicentric giant cell tumor have been reported on in the literature. This series presents 3 additional cases of multicentric giant cell tumor, includes updated data for 2 patients previously reported on in the literature, and reviews 24 cases previously reported on in detail in the literature. The mechanism by which giant cell tumor involves multiple locations is not known. Multicentric giant cell tumor, in contrast to unifocal giant cell tumor, has a tendency to involve the hands, feet, and metaphysis/diaphysis of long bones and to occur in a slightly younger population. In 15 of the 29 patients reviewed, a second lesion did not develop for > 2 years after their initial presentation. Eighteen of those 29 patients had > 2 sites of tumor involvement, 1 of whom had 11 lesions. Two of the 5 patients in the authors' series presented with a spectrum of disease activity, with latent, active, and aggressive lesions present throughout the observation period.
