Traumatic hemipelvectomy is rarely observed because very few patients have survived from the initial trauma. We describe one male child who survived from this massive trauma with a good functional outcome. The boy was 28 months old when he was accidentally struck by a truck. He had severe open trauma of the pelvis and hemorrhage of the left lower limb. Amputation of the left hemipelvis, colostomy, cystostomy and removal of the left avulsed testicle were performed. Once healing had been achieved, he was transferred to our Department of Physical Medicine and Rehabilitation and rehabilitative management was begun, including prosthetic measurement and psychologic intervention for the patient and his parents. For 13 years of long-term follow-up, his prosthesis was readjusted annually. Now he is a 16-year-old middle school student. He is functioning remarkably well with a prosthesis. The psychologic report shows that he is emotionally stable and has good scholastic performance. Although hemipelvectomy appears to be a radical procedure in children, the potential for rehabilitation in a group of children before body image has developed appears to be unexpectedly good.

The treatment of malignant tumors of the pelvic bone has been considered difficult. Many authors have reported lower rates of patients survival and high rates of complications after treatment of the malignant bone tumors of the pelvis. The size of the tumors often much greater than in other sites. Surgical resection and reconstruction often are more complex, based on the proximity of neurovascular structures. Resection of the tumor varies widely in size, type and location of the lesion. After resection of the tumor, reconstruction restoring anatomy of the pelvis and hip, maintaining the limb length and retaining function of the hip joint are challenging procedures. Reconstructions depend on extent and types of resection, type I(iliac). type II(periacetabular) and type III(pubic or ischial) and combined resection. Although limb salvage procedures are advisable in most of patients, there are times when external hemipelvectomy should be considered the treatment of choice. If surgical margin is not safe, or if major neurovascular structures are sacrificed for the wide resection, and consequently residual limbs are functionless, external hemipelvectomy should be considered. Once limb salvage surgery with resection is chosen as the most appropriate treatment for the patient, careful decision should be made whether reconstruction is necessary and what type of reconstruction is necessary. Most of type I resection could be reconstructed with sacroiliac arthrodesis with a recycled autograft or allograft. The vascularized bone graft may be augmented. Type II resections could be reconstructed with saddle prosthesis or recycled autograft with prosthesis composite. Type III resections are usually not necessary for reconstruction due to little functional impairment. However, most of type I, II combined resection and type I, II, III combined resection are almost impossible to solid reconstruction, and are not advisable to reconstruction. At times, it is appropriate to leave patients with a pseudarthrosis. Reconstruction should be individualized by types and extent of resection.

We report a case of hemipelvectomy, which was successfully treated with custom-molded supportive seating and a cosmetic prosthesis. A 32-year-old woman with a history of right traumatic hemipelvectomy, 24 years ago, visited our outpatient clinic for proper prosthetic rehabilitation. After injury, she was not able to use functional prostheses because of persistent skin problems of the hemipelvectomy site. She was able to perform all activities of daily living independently, but had to rely on crutch walking and was not able to sit on an even surface for longer periods of time. With the molded supportive seating the patient was able to perform outdoor activities for up to 10 hours. This case shows an approach in amputee rehabilitation, in which the ultimate goal of prosthetic fitting is not independent walking, but the improvement of independence and hence the improvement of quality of life.

OBJECTIVETo discuss the resection of tumors, reconstruction of defects.

METHODSSixty-one patients with tumors in ileum were treated surgically in People's Hospital from July 1998 to July 2004. The series comprised 38 males and 23 females with an average age of 43 years old (range from 12 to 78 years old). According to Enneking staging system, 36 cases had lesions in region I, 17 cases in region I and II, and 8 cases in region I and IV. After tumor resected, posterior fixation system of spine was applied to reconstruct the integrality of pelvic ring in series of region I cases. The four pedicle screws were implanted in the lumbar and sacrum superiorly, pubis and ischium inferiorly. For children patients, bone graft or bone cement and Steinmann's pins internal fixation was applied to reconstruct the pelvis.

RESULTSAmong all the 61 cases, 48 cases followed up from 16 months to 6 years. Thirty-three cases were survived and had no local recurrence or metastasis. Fifteen cases were dead. Oncology result: local recurrence were found in 19.4% patients with region I resection (7/36), the resection level was close to acetabulum (in order to reserve the acetabulum), and it might be the reason of recurrence. 35.3% of patients (6/17) with region I and II resection had local recurrence, the recurrence maybe related to residual tumor after curettage. 50.0% of the patients (4/8) with region I and IV resection had local recurrence, the tumor residual in sacrum might be the reason of recurrence. Functional result: all of the 36 cases received region I resection regained normal walking function. The hip joint function was normal in 17 cases received tumor curettage, bone cement or hip joint replacement.

CONCLUSIONSThe posterior fixation system of spine can be used to reconstruct the integrality of pelvic ring after resection of iliac tumors. Simple reconstruction is more favorable for child patients. Allograft or self-ileum can be implanted in the space of sacral wing and residual ileum, and the bone graft is fixed with compressional screw.

PURPOSE: It is generally accepted that bony reconstruction after type III (pubic) internal pelvectomy is not necessary. However, technical problems in type III resection, functional outcome according to the extent of resection, and the usefulness of synthetic material to decrease the risk of hernia has not been well addressed. MATERIALS AND METHODS: Fifteen patients who underwent type III internal pelvectomy were extracted and the pathologic diagnosis, Enneking's stage, location of tumor and size, operation time, amount of transfusion, surgical margin, local recurrence, distant metastasis, and functional outcomes were analyzed according to the extent of resection. RESULTS: Pathologic diagnosis was chondrosarcoma in 9, Ewing's sarcoma in 3, metastatic carcinoma in 2, and osteosarcoma in 1 patient. There were 4 patients with local recurrence and one with concomitant lung metastasis. Average Musculoskeletal Tumor Society functional score was 26.7. According to the extent of resection, functional score of 7 cases with unilateral both rami (6) or ischium (1) resection was 26, 4 cases with unilateral both rami and partial contralateral pubic ramus resection was 25, and 4 cases with unilateral both rami including ischium was 24. Two patients had tumor related complication. One patient with a huge intrapelvic tumor aroused at the symphysis pubis showed urethral invasion at presentation, therefore, urethral resection and permanent suprapubic cystostomy was inevitable. The other patient with bilateral pubic ramus involvement by tumor showed caudal displacement of the uterus after pregnancy (4 years after primary resection). She underwent Caesearian section for delivery. CONCLUSION: Regardless of the extent of pubic bone resection, functional outcome was similar. The risk of abdominal or pelvic organ hernia was minimal even without the use of artificial material for soft tissue reconstruction; however, when the extent of resection crosses the symphysis pubis, selective application of an additional procedure to reinforce the pelvic floor may be considered.

OBJECTIVESTo investigate the clinical outcome of consecutive pelvic osteosarcoma treated with surgery and chemotherapy in a single institution, and to discuss the surgical strategy, resection and reconstruction.

METHODSTwenty-one consecutive cases with pelvic osteosarcoma underwent surgical procedures between June 2000 and June 2009. There were 12 male and 9 female with a mean age of 32 years. According to Enneking and Dunham pelvic classification system, type Iwas 3 cases, type I+IV 3 cases, type I+II 4 cases, type II+III 4 cases, type I+II+III 1 case, type III 1 case, and type I+II+IV 5 cases. Among the 21 cases, 19 were diagnosed as classical osteosarcoma and 2 were diagnosed as low-grade pathologically. All the tumors were stage IIB. All the patients received en-bloc resection with 13 wide resection and 8 marginal resection. Thirteen patients underwent modular hemi-pelvic endoprosthesis reconstruction, and 5 patients underwent rod-screw system reconstruction combined with autograft. Two patients received hemipelvectomy and one type III patients had resection without reconstruction. The mean follow-up period was 30.3 months (range, 6.0-87.0).

RESULTSThirteen patients out of 21 survived after treatment. The overall survival rate was 61.9%, and 23.8% patients were alive without disease. The estimated 5-year survival rate was 44.2% based on Kaplan-Meier curve. The local recurrence rate was 28.6%, among which 4 cases were type II resection, 1 was type I resection, 1 was type I+IV resection.No local relapse was found on the hemipelvectomy and type III resection cases. The local recurrence rate after wide resection was 23.1%, and 37.5% for marginal resection.Nine patients had lung metastases and one patient was found bone and lymph node metastases. The MSTS 93 function score was 20.6 ± 5.4 for 13 patients, and 22.5 ± 2.1 for rod-screw reconstruction cases. The function score was 17.7 ± 5.5 for hemi-pelvic prosthetic reconstruction.

CONCLUSIONLimb salvage procedures could be performed on most pelvic osteosarcoma cases, and satisfying function outcome could be achieved with proper reconstruction, however, the overall survival is still lower compared with those in extremities.

OBJECTIVETo discuss the resection of tumors, reconstruction of defects and the postoperative complications.

METHODSThirty-one patients with tumors around acetabular were treated surgically in People's Hospital between July 1997 and July 2003. The series comprised 19 males and 12 females. Twelve patients were diagnosed with chondrosarcoma, 1 with Ewing sarcoma, 3 with osteosarcoma, 1 with lymphoma, 1 with carcinosarcoma, 1 with malignant fibrohistiocytoma (MFH), 2 with myeloma, 9 with giant cell tumor (GCT), 1 with aneurysmal bone cyst. Among 31 patients with peri-acetabular tumors, 8 were reconstructed with hemi-pelvic prosthesis, 7 with saddle prosthesis, 6 with cauterized tumor bone and total hip arthroplasty, 10 with total hip replacement after curettage of lesion and cemented.

RESULTSAmong 21 patients who underwent tumor resection and reconstruction in region II, 6 had local relapse. Two of 3 patients with osteosarcoma were dead. Five of 12 patients with chondrosarcoma were free of disease. Twenty-one patients with acetabular reconstruction after resection of lesions in region II could sit and stand normally and walked with a cane, several of which even had normal gait.

CONCLUSIONAllograft or pelvic prosthesis can be used to reconstruct the acetabulum after resection of tumors. We must pay more attention on the following points in the surgical treatment of periacetabular tumors: (1) Extensively resect tumors as far as possible; (2) Be acquainted with advantages and disadvantages of different reconstructive methods of acetabulum to prevent the complications; (3) The reconstructed acetabulum is unstable, so the patients must stand with a cane to protect the reconstructed hip joint; (4) Prevent wound necrosis and infection; (5) Surgical treatment of pelvic tumors would easily result in poor wound healing especially in the patients receiving chemotherapy or radiotherapy because of extensive soft tissue stripping. The destroyed soft tissue caused by chemotherapy or radiotherapy may increase the great tissue tension after implantation of allograft. And the factors of poor blood supply and hematoma in the wound theoretically increase the chance of infection.
