RESUMO
<p><b>OBJECTIVE</b>To investigate the clincial effects and feasibility of anterior thoracoscopically assisted surgery (TAS) with posterior one-stage total en block spondylectomy(TES) for thoracic spinal tumour.</p><p><b>METHODS</b>From October 2014 to January 2016, 4 patients with thoracic spinal tumour were treated by anterior thoracoscopically assisted surgery with posterior one-stage total en block spondylectomy. There were 2 males and 2 females, aged 16, 35, 46, 60 years. Courses of disease were 1, 4, 6, 9 months. The tumor occurred at T₄, T₆, T₁₃₀ segment in 1 case respectively, at double T7/T8 segments in 1 case. Preoperative visual analogue scores(VAS) were 4, 5, 6, 8 points. Frankel grade of neurologic function was grade B in 2, D in 1, and E in 1. SF-36 quality of life scores were 38, 65, 35, 29 points, including 2 cases of primary spinal tumors, 2 cases of metastatic spinal tumors. According to the classification of Tomita, 1 case was type III, 2 cases were type IV, 1 case was type VI. And according to the WBB staging, 4-9/ABCD was in 2 cases, 5-8/ABC compliated with 1-3 was in 1 case, 6-7/ABC was in 1 case. Surgical procedure: With lateral position, the thoracoscope channel was inserted. The involved intervertebral vessels and corresponding intercostal vessels were ligated, while the prevertebral large vessels were completely separated and protected. The front halves of superior and inferior involved vertebral discs were removed. Then the patients were changed to prone position, posterior one-stage total en block spondylectomy, titanium cage bone graft (allograft bone), pedicle screw fixation were performed.</p><p><b>RESULTS</b>All of the operations were successful and the patients were followed up for 34, 10, 11, 12 months. Pleural effusion occurred in 1 case after operation, and pleural closed drainage was done. All incisions got primary healing; and all patients showed significant pain relief (<0.005), with the VAS score decreasing to 2(2 cases) and 3(2 cases) scores, 2 months after surgery. No nerve functional injury aggravated. SF-36 quality of life score obviously improved with postoperative scores for 88, 92, 71, 80 at 3 months after operation. No recurrent vertebral tumor, internal fixation lossening or breakage was found at follow-up points of 3, 6, 12 months. One patient with lung cancer died of multiple organ failure at 11 months after operation.</p><p><b>CONCLUSIONS</b>With anterior TAS, vertebral anterior vessels, intervertebral blood vessels, intercostal vessels were successfully separated or ligated, intraoperative bleeding was effectively controlled, lung and esophagus were effectively protected, and the tumor received wide excision. Anterior TAS and one-stage posterior TES could significantly reduce the surgical trauma and the risk of surgery.</p>
RESUMO
<p><b>OBJECTIVE</b>To explore clinical outcomes of retrograde interlocked intramedullary nailing with tibia bone graft fusion in treating end-stage ankle arthritis.</p><p><b>METHODS</b>From November 2014 to April 2016, 22 patients with end-stage ankle arthritis were treated with retrograde interlocked intramedullary nailing with tibia bone graft fusion, including 9 males and 13 females aged from 30 to 65 years old with an average of 48.5 years old. Seven patients had obvious varus deformity, and other 15 patients' appearance were normal. Operative time, blood loss, fracture healing time and complications were observed and compared, AOFAS and VAS score were applied for evaluate ankle joint function and pain degree before operation and 9 months after operation.</p><p><b>RESULTS</b>All patients were followed up from 12 to 24 months with an average of 18.6 months. The incision were healed at stage I , and no complications occurred. Operative time ranged from 80 to 120 min with an average of 90 min;blood loss ranged from 15 to 50 ml with an average of 30 ml;fracture healing time was from 10 to 18 weeks with an average of 14 weeks. AOFAS score at 9 months after operation was 88.00±3.45, while 54.82±2.98 before operation, and there was statistical significance; 8 cases obtained excellent results, 12 good and 2 moderate. There was significant difference in VAS score between preoperative(3.96±1.27) and 9 months after operation(9.37±0.55).</p><p><b>CONCLUSIONS</b>Retrograde interlocked intramedullary nailing with tibia bone graft fusion for the treatment of end-stage ankle arthritis has advantages of stable fixation, less trauma, less blood loss, bone union and rapid recovery of function, and could relieve pain obviously.</p>
RESUMO
Madelung deformity is a rare deformity of forearm and wrist caused by growth disorders of distal radius ulnar and palmar epiphyseal. Current studies showed that its incidence mainly associated with trauma, epiphyseal developmental abnormalities, nutritional disorders and genetic deletion or mutation. The early clinical presentation is not typical, in middle and late time, wrist deformity and weak can appear. Plain film considered as the main means of diagnosis is often lack of early diagnosis significance. Although wrist joint magnetic resonance imaging showing early soft tissue and skeletal abnormalities were used for the early diagnosis of the disease, current domestic study in magnetic resonance imaging of this deformity is less. According to the size of the distal ulnar inclination angle and palm angle, this deformity can be divided into different types. The patients with severe deformity and symptoms usually need surgical intervention including ulna revision and osteotomy of the distal radius at present. Although the two operation can achieve good clinical results, the surgical trauma, infection and postoperative risk of joint activities are more.
