OBJECTIVETo investigate the reconstruction of thumb II-III degree defect by big toe wrap-around flap combined with second toe proximal interphalangeal joint.

METHODSBetween May 2004 to July 2012, 25 cases with thumbs II-III degree defects were treated. The ipsilateral big toe wrap-around flap combined with second toe proximal interphalangeal joint was designed to reconstruct the thumb defects based on the thumb size on the healthy side. The distal end of hallux was covered by flap at tibial side. The wound at the fibula side was covered by skin graft and flap. The bone defect at the second toe was filled with remnant hallux or iliac bone.

RESULTSAll the 25 reconstructed thumbs survived completely. The patients were followed up for 6-26 months without any joint degeneration. According to the finger reconstruction functional criterion publicized by China Medical Association, the finger function was assessed as excellent in 10 case, good in 11 cases, poor in 4 cases. Joint necrosis happened in 2 cases and bone malunion in 2 cases. The 4 cases received dead bone debridement and iliac bone graft. No malfunction occurred in the donor site.

CONCLUSIONSOur surgical method is a currently effective way to reconstruct II-III degree thumb defects. Satisfactory functional and cosmetic results can be achieved both in donor site and recipient site.

BACKGROUND: Total hip arthroplasty (THA) for severe developmental dysplasia of the hip (DDH) is a technically demanding procedure for arthroplasty surgeons, and it is often difficult to reduce the hip joint without soft tissue release due to severe flexion contracture. We performed two-stage THAs in irreducible hips with expected lengthening of the affected limb after THA of over 2.5 cm or with flexion contractures of greater than 30 degrees in order to place the acetabular cup in the true acetabulum and to prevent neurologic deficits associated with acute elongation of the limb. The purpose of this study is to evaluate the outcomes of cementless THA in patients with severe DDH with a special focus on the results of two-stage THA. METHODS: Retrospective clinical and radiological evaluations were done on 17 patients with Crowe type III or IV developmental DDH treated by THA. There were 14 women and 3 men with a mean age of 52.3 years. Follow-ups averaged 52 months. Six cases were treated with two-stage THA followed by surgical hip liberalization and skeletal traction for 2 weeks. RESULTS: The mean Harris hip score improved from 40.9 to 89.1, and mean leg length discrepancy (LLD) in 13 unilateral cases was reduced from 2.95 to 0.8 cm. In the patients who underwent two-stage surgery, no nerve palsy was observed, and the single one-stage patient with incomplete peroneal nerve palsy recovered fully 4 weeks postoperatively. CONCLUSIONS: The short-term clinical and radiographic outcomes of primary cementless THA for patients with Crowe type III or IV DDH were encouraging. Two-stage THA followed by skeletal traction after soft tissue release could provide alternative solutions to the minimization of limb shortenings or LLD without neurologic deficits in highly selected patients.

OBJECTIVETo study the clinical manifestations, radiologic findings, pathologic diagnosis and differential diagnosis of primary osteosarcoma in elderly patients.

METHODSTwelve cases of primary osteosarcoma occurring in patients older than 60 years were encountered during the period from 1985 to 2010. The clinical manifestations, radiologic features and pathologic findings were studied and the follow-up data were analyzed.

RESULTSThe sites of involvement included long bones (number = 7), ilium (number = 1), craniofacial bones (number = 2) and soft tissue (number = 2). Radiologic examination showed a mixture of osteosclerotic and osteolytic lesions in 10 patients, soft tissue lesions with high-density areas in 2 patients and soft tissue lesions with periosteal reaction in 8 patients. Histologically, most cases showed features of conventional osteosarcoma. There were 2 cases of malignant fibrous histiocytoma-like osteosarcoma, 2 cases of chondroblastic osteosarcoma and 1 case of well-differentiated intraosseous osteosarcoma. Immunohistochemical study played little role in pathologic diagnosis. Ten patients had undergone amputation, including one patient who had received adjuvant chemotherapy beforehand. Nine patients had follow-up information available. Three of them died of lung metastasis and 1 died of cardiovascular disease.

CONCLUSIONSPrimary osteosarcoma rarely occurs in elderly patients and can easily be missed. Correlation with clinical, radiologic and histologic features is important for arriving at a correct diagnosis.

OBJECTIVETo study the clinicopathologic features and differential diagnosis of epithelioid sarcoma-like hemangioendothelioma (ES-H).

METHODSThe clinical, radiologic and pathologic features of three cases of ES-H were analyzed.

RESULTSAll the 3 cases occurred in male adults. The age ranged from 44 to 53 years. The presentations included left neck mass, iliac pain and bilateral shoulder masses. Histologically, ES-H was composed of a mixture of spindle and epithelioid tumor cells. Transition between the two cell types was demonstrated. The tumor cells were arranged in compact sheets, vague nodules or intersecting fascicles, amongst a collagenous stroma. Central coagulative necrosis was identified in one case, reminiscent the morphology that seen in epithelioid sarcoma. There was no evidence of angiogenesis, though focal presence of intracytoplasmic vacuoles was seen in one case, as in classic examples of epithelioid hemangioendothelioma. Immunohistochemical study showed that the tumor cells expressed both epithelial (AE1/AE3, CAM5.2 and epithelial membrane antigen) and endothelial (CD31, Fli-1 and factor VIII-related antigen) markers. Two of the cases were also positive for CD34. All of the patients were treated by surgical resection. Two patients remain well at 14-month and 9-month follow up, respectively. The remaining patient had repeated local recurrences during a 6-year period.

CONCLUSIONSES-H represents a rare morphologic type of hemangioendothelioma. It has some overlapping histologic features with epithelioid sarcoma and epithelioid hemangioendothelioma. The endothelial nature of ES-H is difficult to be verified on the basis of morphologic examination alone. Confirmation of the diagnosis with immunohistochemistry is necessary. ES-H is likely related to epithelioid hemangioendothelioma and may represent a cellular spindle cell variant of epithelioid hemangioendothelioma.

OBJECTIVETo study the feasibility and authenticity of repairing alveolar defects in alveolar cleft patients with osteoinduction active material (OAM) in clinic.

METHODSTwenty-seven cases of alveolar defect chosen from clinic were divided into two groups (test group and control group). For test group (12 cases), OAM was transplanted to repair the alveolar cleft. For control group (15 cases), autogenous ilium cancellous bone were transplanted into the defect region to repair alveolar cleft. At 6 months after operation, CT and three-dimensional reconstruction were used to observe alveolar appearance, and the effect and clinical success rate of recover alveolar cleft by using different repair material were compared.

RESULTSIn the 27 cases, all the maxillary continuity was restored except two of test group and two of control group. There was no significant difference between test group and control group regarding the clinical success rate of the alveolar cleft repair (P = 1.000).

CONCLUSIONOAM was used to repair the alveolar cleft that can result in new bone formations and the burgeon of canines from the bone grafted areas. There is no significant difference between OAM and autogenous ilium cancellous bone regarding the effect of the alveolar cleft repair.

INTRODUCTIONGiant cell tumours of the bone are aggressive and potentially malignant lesions. Juxtaarticular giant cell tumours of the lower end radius are common and present a special problem of reconstruction after tumour excision. Out of the various reconstructive procedures described, non-vascularised fibular autograft has been widely used with satisfactory functional results.

MATERIALS AND METHODSTen patients with a mean age of 33.4 years, with either Campanacci grade II or III histologically proven giant cell tumours of lower end radius were treated with wide excision and reconstruction with ipsilateral non-vascularised proximal fibular autograft. Host graft junction was fixed with dynamic compression plate (DCP) in all cases. Wrist ligament reconstruction and fixation of the head of the fibula with carpal bones and distal end of the ulna using K-wires and primary cancellous iliac crest grafting at graft host junction was done in all cases.

RESULTSThe follow-up ranged from 30 to 60 months (mean, 46.8). At last follow-up, the average combined range of motion was 100.5 degrees with range varying from 60 degrees to 125 degrees. The average union time was 7 months (range, 4 to 12). Non-union occurred in 1 case. Graft resorption occurred in another case. Localised soft tissue recurrence occurred in another case after 3 years and was treated by excision. There was no case of graft fracture, metastasis, death, local recurrence or significant donor site morbidity. A total of 3 secondary procedures were required.

CONCLUSIONSEnbloc resection of giant cell tumours of the lower end radius is a widely accepted method. Reconstruction with non-vascularised fibular graft, internal fixation with DCP with primary corticocancellous bone grafting with transfixation of the fibular head and wrist ligament reconstruction minimises the problem and gives satisfactory functional results.
