Huge Intraosseous Tibial Haemangioma Managed with Embolisation, Excision and Fibular Ilizarov Reconstruction: A Case Report.

AIM: Our aim is to report the successful treatment of an intraosseous haemangioma of tibia with an atypical presentation through a multidisciplinary approach of preoperative embolisation, a subtotal resection of the tibia and subsequent reconstruction with the Ilizarov medial fibular translation technique. BACKGROUND: En bloc excision is the treatment of choice for large tumours of the tibia. However, there is no single recommended method for the reconstruction of the resulting bony defect. CASE: A 22-year-old female presented with a massive intraosseous haemangioma of the entire tibia. Sequential, multimodal treatment consisted of (1) preembolisation, (2) en bloc resection and (3) reconstruction of the extensive skeletal defect via the Ilizarov method of fibular medialisation. Radiologic union occurred at 6 months and graft hypertrophy at 22 months. At 45 months, the patient was fully weight-bearing without need for an assistive device. CONCLUSION: Resection and reconstruction of a large intraosseous haemangioma of the tibia can be treated successfully using a well-planned sequential management of embolisation, resection and Ilizarov fibular grafting. SIGNIFICANCE: This report highlights the successful management of an unusually extensive and difficult tumour through appropriate and meticulous perioperative multidisciplinary planning, execution and follow-up.

Giant cell tumor of the small bones of the foot.

AIMS: This study aims to determine whether giant cell tumor of bone of the foot (GCTB-F) is more aggressive than GCTB at other sites using data from a single institution. PATIENTS AND METHODS: We reviewed all patients with GCTB seen by our Unit from 1993 to 2012. Patients with GCTB-F were compared with all other patients with GCTB in terms of demographics and presentation. This group of GCTB-F was then compared with patients with GCTB of the appendicular skeleton (GCTB-AS) in terms of treatment and oncologic outcome at follow-up of at least 2 years. RESULTS AND CONCLUSION: There were seven patients with GCTB-F (2.6%), most consulted over 12 months after symptoms. Compared to other GCTB ( n = 262), a bigger proportion of patients (28.5%) presented as recurrent lesions. All seven patients were classified as Campanacci III but none had lung metastasis at presentation or on follow-up. Compared to the group of 124 GCTB-AS, no GCTB-F patient received intralesional surgery. The 14% recurrence rate can be explained by contaminated non-intralesional surgery due to the advanced presentation and the technically challenging architecture of the foot. It would seem the aggressive tag of GCTB-F is not due to aggressive biologic behavior but to a combination of delayed presentation, delayed diagnosis, and difficult surgery.

The relationship of the posterior interosseous nerve to the supinator muscle in the dorsal approach to the proximal radius: A descriptive and quantitative anatomic study of Filipino cadavers

@#<p style="text-align: justify;"><strong>BACKGROUND AND OBJECTIVE:</strong>The posterior interosseous nerve (PIN) is vulnerable to injury in the dorsal approach to the proximal radius. The goal of this study is to describe the quantitative relationship of the PIN to the supinator muscle in the context of anatomic landmarks. Knowledge of superficial landmarks related to the PIN would hopefully minimize iatrogenic injury to the posterior interosseous nerve.<br /><strong>METHODS:</strong> 12 cadavers (22 forearms) were dissected and analyzed. The length of the supinator muscle was determined. The oblique distances of the PIN entry and exit points to the proximal and distal borders of the supinator muscle as well as their perpendicular distances to the lateral epicondyle-Lister's tubercle (LE-LT) reference line were measured and recorded. The number of PIN branches inside the supinator substance was recorded. Mean and median values were determined and subjected to statistical analysis.<br /><strong>RESULTS:</strong> Mean supinator length was 5 centimeters. Ninety-one percent of the cadaveric forearms had PIN branches inside the supinator muscle substance. Twelve of the 22 forearms (55%) had 2 branches. The mean oblique distances of the PIN from the lateral epicondyle to the entry and exit points in the proximal and distal borders of the supinator muscle was 3.52 and 7.31 centimeters, respectively. The mean perpendicular distances of the PIN from LE-LT reference line to the entry and exit points in the proximal and distal borders of the supinator muscle was 1.13 and 1.26 centimeters, respectively. An imaginary danger-zone 4 centimeters wide overlying the LE-LT reference line depicts the possible area where the PIN and its branches may most likely be located.<br /><strong>CONCLUSION:</strong> The dorsal approach to the proximal radius may allow a safe exposure without causing iatrogenic injury to the posterior interosseous nerve through the use of superficial anatomic landmarks and reference lines in combination with mean measurements from our study.</p>

The prognostic value of pathologic fractures in patients with high-grade classic osteosarcoma

Pathologic fracture in osteosarcoma has traditionally been associated with a poor prognosis and is an immediate indication for amputation of the affected extremity. This concept has been questioned and remains an area of debate, especially because advances in osteosarcoma treatment have today resulted in better survival and limb salvage rates. It is the objectives of this paper to analyze the survival and limb salvage rate of osteosarcoma patients presenting with pathologic fractures and compare these with the population of osteosarcoma patients without pathologic fractures. Over a 15-year period (1993-2008), these were 84 patients presenting with non-metastatic high-grade classic osteosarcoma of the extremities (Enneking Stage IIB) who received complete treatment from the University of the Philippines-Musculoskeletal Tumor (UP-MuST) Unit and who had a follow up of at least 2 years. Ten of these 84 patients had pathologic fractures prior to surgery. Their overall survival was 50%, similar to the 50.38% overall survival of the entire group of 84 osteosarcoma patients. Limb salvage rate was 60%, similar to the 59% rate of patients without pathologic fractures. This study shows that contrary to traditional teaching, overall survival for this subset of osteosarcoma patients with pathologic fractures is acceptable at 50% and is equal to that of the entire group of osteosarcoma patients. At the same time, successful limb salvage surgery is possible despite the presence of a pathologic fracture, especially in patients with good response to chemotherapy.

Vascularized proximal fibular epiphyseal transfer for shoulder reconstruction after tumor resection

We present a case of an 8-year-old girl with a high grade osteogenic sarcoma of the proximal humerus treated with wide resection and vascularized proximal humerus treated with wide resection and vascularized proximal fibular epiphyseal transfer. At 5 years after reconstruction, the patient is tumor free and had a Musculoskeletal Tumor Score of 26/30 or 86.7%. The functional outcomes in terms of shoulder range of motion and pain were good. Complications include transient peroneal nerve palsy and mild valgus instability of the knee.

Osteosarcoma in the preadolescent Filipino patient

Objective. Classic high-grade osteosarcoma is uncommon in preadolescents (less than or equal to 10 years of age). The possibilities of clinicopathologic differences from the typical adolescent osteosarcoma patient have been raised. We sought to compare the presentation, treatment and survival of this subgroup of patients with published rates in order to determine if there is a need to use a treatment regimen different from that for regular adolescent osteosarcoma patients. Methods. Records of the University of the Philippines-Musculoskeletal Tumor Unit (UP-MuST) over a 15-year period (1993-2008) were reviewed and data collected on patients 10 years and younger with biopsy-proven classic high-grade intramedullary osteosarcoma who underwent complete treatment by the Unit. Demographics and survival rates were then compared with published rates for preadolescent and regular adolescent osteosarcoma cases. Results. There were fourteen patients; (6M:8F; age: 4-10 years). The most common presentation was a painful mass in the distal femur (8); the tumors most commonly had osteoblastic histology (12). Treatment consisted of neoadjuvant chemotherapy, wide surgical excision through ablation (9) or limb-saving surgery (5), and postoperative chemotherapy. There was a good histologic response (over 90% tumor necrosis) in four patients. Seven patients are ANED (alive no evidence of disease) 25 to 186 months after diagnosis. Five-year survival estimate is 52%, compared to a dismal 5 to 10% 15 years ago. Conclusion. Clinicopathologic presentation, clinical course, and overall survival in this subgroup of patients are comparable with published results for both preadolescent and adolescent osteosarcoma patients. There is no need to alter the present treatment regimen for this group of young patients.

Osteosarcoma of the spine- A dilemma in diagnosis and management

Osteosarcoma of the spine accounts for 1 to 3 percent of osteosarcoma. When this afflication of the spine occurs, it is often fraught with diagnostic dilemmas and treatment challenges.OBJECTIVE: This manuscript reports on the cases reported over a 15- year period from the UP Musculoskeletal Tumor Unit. Only 2 of the 3 cases were available for review.RESULTS: Both patients were initially misdiagnosed. This delay in diagnosis led to a delay in instituting appropriate chemotheraphy inevitable causing poor outcomes of treatment.CONCLUSION: This report highlights the dilemma of treating a difficult site. Spinal osteosarcoma presents with numerous diagnostics and management obstacles. Unless clinician awareness is improved and these treatment options become available to patients, prognosis will not improve.
