OBJECTIVE: To introduce a surgical approach for reconstruction of nail folds in congenital complete syndactyly release. METHODS: A narrow flap and a broad flap were raised on the common distal phalanx to cover the denuded nail-edge in 30 fingers of 15 cases whose webs were separated. RESULTS: All of the flaps were successfully transferred and survived. The reconstructed nail folds had satisfied figure in 21 out of 30 fingers. The nail folds in the other 9 fingers, covered by a broad flap in 2 fingers and by a narrow flap in 7 fingers, were a little smaller than normal. All of the 30 fingers had normal fullness of pulp and no twisty nails. CONCLUSION: The reconstruction of nail folds by double pulp flap can be performed with a one-stage technique, and the outcome is satisfactory, which make it as a good surgical approach to reconstruct nail folds in congenital complete syndactyly release.
Objective To assess the influence of different digestive tract reconstruction on the blood glucose of gastric antral cancer patients with type 2 diabetes. Methods The clinical data of 51 cases of gastric antral cancer with type 2 diabetes treated radical surgery in this hospital from January 2006 to January 2012 were analyzed retrospectively. The patients were divided into three groups according to the different digestive tract reconstruction methods：BillrothⅠ anastomosis group （n=14）， BillrothⅡ anastomosis group （n=28）， and Roux-en-Y anastomosis group （n=9）. The indexes were analyzed and compared among three groups：① The levels of fast blood glucose （FBG） and 2h postprandial blood glucose （PG2h） were detected before operation and on 1 month and 6 months after the operation；② The level of glycated hemoglobin （HbA1c） was detected before operation and 6 months after the operation；③ The diabetes control was observed. Results The FBG and PG2h levels in the BillrothⅠ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those detected before the operation （P＞0.05）. The FBG and PG2h levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group detected on 1 month and 6 months after the operation were significantly lower than those before the operation respectively （P＜0.05）. The FBG and PG2h levels in the BillrothⅡ anastomosis group detected on 1 month and 6 months after the operation were not statistically different from those in the Roux-en-Y anastomosis group respectively （P＞0.05）， but which were markedly lower than those in the BillrothⅠ anastomosis group， the differences were statistically significant （P＜0.05）. The HbA1c levels in the BillrothⅠ anastomosis group detected before the operation and on 6 months after the operation were not statistically different from each other （P＞0.05）. The HbA1c levels in the BillrothⅡ anastomosis group and Roux-en-Y anastomosis group detected on 6 months after the operation were markedly lower than those before the operation and the difference was statistically significant （P＜0.05）. On 6 months after the operation， the HbA1c levels in the BillrothⅡanastomosis group and Roux-en-Y anastomosis group were markedly lower than those in the BillrothⅠ anastomosis group and the differences were statistically significant （P＜0.05）；the HbA1c level was not statistically different between the BillrothⅡ anastomosis group and the Roux-en-Y anastomosis group （P＞0.05）. The total curative effects in the BillrothⅡ anastomosis and Roux-en-Y anastomosis groups were significantly better than those in the BillrothⅠ anastomosis group （P＜0.05）. Conclusion According to our limited clinical data， BillrothⅡ anastomosis and Roux-en-Y anastomosis for gastric antral cancer patients with type 2 diabetes may be the best surgical approach.
With the developing of three-dimensional (3D) printing technology, it is widely used in the treatment of bone tumors in the clinical orthopedics. Because of the great individual differences in the location of bone tumor, resection and reconstruction are difficult. Based on 3D printing technology, the 3D models can be prepared to show the anatomical part of the disease, so that the surgeons can create a patient-specific operational plans based on better understand the local conditions. At the same time, preoperative simulation can also be carried out for complex operations and patient-specific prostheses can be further designed and prepared according to the location and size of tumor, which may have more advantages in adaptability. In this paper, the domestic and international research progress of 3D printing technology in the treatment of limb bone tumors in recent years were reviewed and summarized.
ObjectiveTo explore the clinical outcomes of acetabular revision using a metal reconstruction cage. MethodsBetween October 2006 and October 2013, 16 patients (16 hips) underwent acetabular revision with a metal reconstruction cage. There were 4 males and 12 females, with the mean age of 62.7 years (range, 49-78 years). The time from total hip arthroplasty to revision was 3-15 years (mean, 8.2 years). The causes for revision were aseptic acetabular loosening in 15 cases, and femoral periprosthetic fracture (Vancouver type B3) in 1 case. According to the American Academy of Orthopaedic Surgeons (AAOS) classification, there were 12 cases of type III and 4 cases of type IV; according to the Paprosky classification, there were 12 cases of type IIIA and 4 cases of type IIIB. Harris score was used for hip function evaluation, and visual analogue scale (VAS) for pain in the thigh. X-ray films were taken for imaging evaluation. ResultsHealing of incision by first intention was obtained in all patients. Deep venous thrombosis occurred in 1 patient, and was cured after anticoagulation therapy. No complications of infection, neurovascular injury, and prosthetic dislocation were found. Sixteen patients were followed up 6.8 years on average (range, 2-9 years). The Harris score was significantly increased from preoperative 42.44±4.66 to 91.88±3.28 at last follow-up (t=–106.30, P=0.00). Two patients had mild pain in the thigh, but pain disappeared at 1 year after operation. At immediate after operation, the abduction angle was 37-54° (mean, 42.9°). The distance between acetabular rotation centre and teardrop line was (33.67±12.19) mm for preoperative value and was (20.67±9.63) mm for postoperative value, showing significant difference (t=–9.60, P=0.00). The distance between acetabular rotation centre and lateral teardrop was (34.98±12.30) mm for preoperative value and was (40.04±6.61) mm for postoperative value, showing significant difference (t=–3.15, P=0.00). X-ray film results showed bony fusion at the osteotomy sites at 4 to 12 months after operation. No continuous radiolucent line, prosthetic dislocation, or osteolysis was found, and bony ingrowth was observed in all patients. No patient received re-revision due to prosthetic loosening. ConclusionThe metal reconstruction cage for acetabular revision can achieve good effectiveness for patients with serious bone defect.
Objective To study diagnosis, treatment and rebuilding of scrotum gangrene. Methods From January 1992 to September 2004, 15 patients with scrotum gangrene were treated and their clinical data were analysed.Their ages ranged from 23 to80 years. The results of bacterial culture were positive for wound sample in 14 cases and for blood in 1 case. All the patients underwent surgical treatment including incision,aggressive debridement,drainage,irrigation and antibiotic therapy. Two patients accepted hyperbaric oxygen therapy. All the patients received scrotum rebuilding by transfer of skin flap, skin grafting and suturation and orchectomy was given in 2 elder patients. Results All the patients received healing by first intention after 21 to 34 days.There was no death. Aftera follow-up of 1 to 3 years, the appearance of scotum was satisfactory and no orchiatrophy occurred. Thirteen patients with testicles had normal sexual function. Conclusion After a definite diagnosis,early aggressive debridement,broad-spectrum antibiotics and sufficient local drainage should be used. If available,hyperbaric oxygen therapy may be used to promote healing of tissue wound. Scrotum should be rebuilt based on different conditions.
【Abstract】ObjectiveTo evaluate the value of MR imaging with a contrast-enhanced multi-phasic isotropic volumetric interpolated breath-hold examination (VIBE) in diagnosis of primary liver carcinoma. MethodsThirty-two consecutive patients with surgical-pathologically confirmed 42 foci of primary carcinoma of liver underwent comprehensive MR examination of the upper abdomen, routine two-dimensional (2D) T1WI and T2WI images were acquired before administration of Gd-DTPA for contrast enhancement. Then, contrast-enhanced multi-phasic VIBE was acquired followed by 2D T1WI images. The lesion appearances on hepatic arterial, portal venous and equilibrium phases of VIBE sequence were carefully observed along with delineation of hepatic arterial and portal venous structures. The lesion detection rates and lesion characterization ability were compared among various MR sequences. Results33(78.6%), 30(71.4%), 38(90.5%) and 42(100%) foci were displayed respectively on T2WI, non-enhanced T1WI, enhanced T1WI and enhanced 3D-VIBE images (P＜0.05). The hepatic arterial anatomy of 30 patients （93.8%） and the portal venous structure of 31 patients （96.9%） were clearly depicted on enhanced 3D-VIBE images. Using MIP and MPR reconstruction techniques, the feeding arteries of 14 foci and draining vein of 12 foci were clearly displayed.ConclusionHigh-quality 3D-VIBE images are not only better than 2D images in lesion detection and characterization for primary liver carcinoma, but also able to provide much more information about hepatic vascular anatomy.
OBJECTIVE: To observe the strength of thigh muscles after reconstruction of anterior cruciate ligament by autogenous bone-patellar tendon-bone graft. METHODS: Twenty-three patients, 9 males and 14 females, were followed up one year after reconstruction of the anterior cruciate ligament with autogenous bone-patellar tendon-bone graft. Through arthroscope, no intra-articular derangement was found. The strengths of isometric and isotonic contractions of the quadri ceps and the hamstrings muscles of the affected and contralateral thighs were recorded. RESULTS: The donor side for autogenous bone-patellar tendon-bone graft showed significant decrease (P lt; 0.01), but no effect on that of the hamstrings muscle(P gt; 0.05). CONCLUSION: To reconstruct the anterior cruciate ligament, harvest of the bone-patellar tendon-bone graft as a reparative material may markedly lower the strength of the quadriceps femoris muscle.
