ObjectiveTo compare the effectiveness between modified ilioinguinal approach combined with Kocher-Langenbeck (K-L) approach and Stoppa approach combined with K-L approach for the treatment of complicated acetabular fractures.MethodsBetween May 2011 and May 2016, Sixty-two patients with complicated acetabular fractures were treated with operation via combined anterior and posterior approaches. Thirty-four cases (group A) were treated with modified ilioinguinal approach combined with K-L approach, and 28 cases (group B) were treated with Stoppa approach combined with K-L approach. There was no significant difference in gender, age, injury causes, the type of fracture, time from injury to operation, and associated injury between 2 groups (P>0.05). The operation time, intraoperative blood loss, and hospitalization time were recorded. X-ray film was performed to evaluate the fracture reduction according to the Matta reduction criteria and observe the fracture healing, osteoarthritis, and heterotopic ossification. Clinical results were evaluated according to the grading system of modified d’Aubigne and Postel.ResultsThere was no significant difference in operation time, intraoperative blood loss, and hospitalization time between 2 groups (P>0.05). Postoperative incision fat liquefaction occurred in 2 cases in group A and group B respectively, and deep vein thrombosis of lower extremity occurred in 1 case in group A. No iatrogenic injury was found in 2 groups. Fifty-six patients were followed up after operation. Thirty patients in group A were followed up 12-48 months (mean, 31.8 months). Twenty-six patients in group B were followed up 12-46 months (mean, 30.2 months). At 12 months after operation, according to the grading system of modified d’Aubigne and Postel, the hip function was rated as excellent in 9 cases, good in 16 cases, fair in 3 cases, and poor in 2 cases, with the excellent and good rate of 83.3% in group A; the hip function was rated as excellent in 7 cases, good in 14 cases, fair in 2 cases, and poor in 3 cases, with the excellent and good rate of 80.8% in group B. There was no significant difference in the hip function between 2 groups (Z=0.353, P=0.724). The X-ray films showed that there were 23 cases of anatomical reduction, 6 cases of satisfactory reduction, and 1 case of unsatisfactory reduction in group A, and 20 cases, 5 cases, and 1 case in group B, respectively. There was no significant difference in the results of fracture reduction between 2 groups (Z=0.011, P=0.991). Fracture healing was observed in both groups. There was no significant difference in fracture healing time between 2 groups (t=0.775, P=0.106). During follow-up, 5 cases of osteoarthritis changes, 2 cases of heterotopic ossification, and 2 cases of avascular necrosis of femoral head occurred in group A, and 4 cases, 2 cases, and 1 case in group B, respectively. The difference between 2 groups was not significant (P>0.05).ConclusionAccording to the location and type of fracture, making a choice between the modified anterior approach and Stoppa approach, and then combined with K-L approach for treatment of complicated acetabular fracture, can obtain satisfactory effectiveness.
ObjectiveTo explore the surgical treatment strategy of the vertebral " shell” after thoracolumbar fracture, and provide clinical reference for the intervention and treatment of " shell”.MethodsBetween June 2015 and January 2017, 53 patients with high risk of vertebral " shell” after thoracolumbar fracture surgery were enrolled in a prospective study according to the selection criteria. All patients were randomly divided into two groups according to the order of treatment, 27 cases in the treatment group were treated with short-segment fixation combined with vertebral reconstruction, 26 cases in the control group were treated with short-segment fixation. There was no significant difference in gender, age, injury cause, Denis classification, fracture segment, the degree of injured vertebra compression, bone mineral density, and American Spinal Cord Injury Association (ASIA) classification between the two groups (P>0.05). The degree of injured vertebra compression, visual analogue scale (VAS) score, and Oswestry disability index (ODI) score at preoperation, immediate after operation, and last follow-up were calculated and compared between the two groups. The " shell” phenomenon and surgery complications were observed at the same time.ResultsAll patients were followed up 12-18 months with an average of 14.4 months. There were 5 cases of " shell” phenomenon in the treatment group and 4 cases of nonunion at last follow-up, 23 cases of " shell” phenomenon in the control group and 19 cases of nonunion at last follow-up; there was a significant difference between the two groups (P<0.05). In the treatment group, 1 case had incision fat liquefaction and 4 cases had bone cement leakage; in the control group, 2 cases had screw loosening and 1 case had unilateral connecting rod rupture; there was no significant difference in the incidence of complications between the two groups (χ2=0.504, P=0.478). The degree of injured vertebra compression, VAS score, and ODI score were significantly improved in both groups at immediate after operation and last follow-up (P<0.05). There was no significant difference in the degree of injured vertebra compression between the two groups at immediate after operation (P>0.05), but which was significantly higher in the control group than that in the treatment group at last follow-up (P<0.05). Except that the ODI score of the control group was significantly higher than that of the treatment group at last follow-up (P<0.05), there was no significant difference in VAS score and ODI score between the two groups at the other time points (P>0.05).ConclusionThe treatment of thoracolumbar fracture with short-segment fixation combined with injured vertebral reconstruction can effectively prevent the " shell” phenomenon, which is conducive to maintaining the height of injured vertebral and improving the long-term function. The effectiveness is satisfactory.
ObjectiveTo investigate the effectiveness of two surgical approaches in the treatment of type Ⅳ Pipkin fracture.MethodsThe clinical data of 15 patients with type Ⅳ Pipkin fracture treated surgically between July 2013 and June 2018 were retrospectively analyzed. According to different surgical approaches, they were divided into group A (8 cases, using K-L posterior approach) and group B (7 cases, using greater trochanter osteotomy approach). There was no significant difference in gender, age, cause of injury, and interval from injury to operation between the two groups (P>0.05). The incision length, operation time, intraoperative blood loss, hospital stay, fracture healing time, and complications of the two groups were recorded. Hip joint function recovery was evaluated according to Thompson-Epstein functional evaluation system.ResultsAll the 15 patients were followed up 1-5 years, with an average of 2.5 years. There was no significant difference in operation time between the two groups (t=14.681, P=0.100); the incision length, intraoperative blood loss, and fracture healing time in group A were all greater than those in group B, and the hospital stay was shorter than that in group B, showing significant differences (P<0.05). In group A, 1 patient presented hip pain, clasthenia, and limited mobility after operation, 1 patient presented ossifying myositis, 1 patient presented osteonecrosis of the femoral head, 1 patient presented fat liquefaction of incision, and 1 patient presented sciatica, with a complication incidence of 62.5%. Postoperative hip pain occurred in 1 patient and ossifying myositis in 2 patients in group B, with a complication incidence of 42.9%. There was no significant difference in the incidence of complications between the two groups (χ2=−0.735, P=0.462). At last follow-up, according to Thompson-Epstein functional evaluation system, the results in group A were excellent in 3 cases, good in 2 cases, fair in 2 cases, and poor in 1 case, with an excellent and good rate of 62.5%; in group B, the results were excellent in 4 cases, good in 2 cases, and fair in 1 case, and the excellent and good rate was 85.7%. There was no significant difference in good and fair rate between the two groups (χ2=−0.990, P=0.322).ConclusionK-L posterior approach is more convenient in the fracture treatment during operation, but it has greater trauma, greater vascular damage, and more blood loss. The greater trochanter osteotomy approach can better protect the blood supply of femoral head, shorten the operation time, reduce intraoperative blood loss, and reduce postoperative complications. It is an ideal way in the surgical treatment of type Ⅳ Pipkin fracture.
ObjectiveTo increase the advantage and decrease the disadvantage of posterior approach for uniportal video-assisted thoracic surgery (VATS) right upper lobectomy.MethodsData of 97 consecutive patients who received uniportal VATS right upper lobectomy using posterior approach in the semiprone position were retrospectively analyzed from Dec, 2014 to Dec, 2017. There were 41 males and 56 females at age of 26–79 (57.8±10.6) years. The hilar structure was cut from posterior to anterior one by one. The mediastinal lymph nodes were dissected if lung cancer was diagnosed.ResultsNinety three of 97 patients were successfully completed with uniportal VATS right upper lobectomy using posterior approach, 3 of them were completed with posterior approach combined with anterior approach, and 1 of them needed thoracotomy. The mean operative time was 76–192 (127.0±32.0) min. The thoracic drainage time was 2–20 (3.4±2.7) d. The postoperative length of hospital stay was 3–23 (5.4±3.1) d. There were postoperative complications in 7 patients and no postoperative mortality.ConclusionPosterior approach for uniportal video-assisted thoracic surgery right upper lobectomy is safe and feasible, which can decrease the fatigue of both the surgeon and the assistant. It also provides with better exposure of posterior mediastinum, less dragging lung, and less interference of the instruments and help keep the clear surgical field. In complicated cases, posterior approach could combine with anterior approach to complete the VATS lobectomy.
Objective To explore the effectiveness and related issues in the treatment of multiple segments of thoracolumbar tuberculosis through posterior unilateral debridement with bone graft and internal fixation. Methods The clinical data of 29 patients with multiple segments of thoracolumbar tuberculosis who met the selection criteria were retrospective analyzed between January 2012 and July 2015. There were 17 males and 12 females, with age of 21-62 years (mean, 37.4 years). Lesions contained 3-8 vertebral segments, including 3 segments in 6 cases, 4-6 segments in 17 cases, and 7-8 segments in 6 cases. The center lesions located at thoracic spine in 8 cases, lumbar spine in 10 cases, and thoracolumbar segment in 6 cases, and thoracic lumbar skip lesions in 5 cases. The complications included vertebral abscess in 7 cases, psoas major abscess in 6 cases, sacral spine muscle abscess in 7 cases, iliac fossa and the buttocks abscess in 1 case, spinal canal abscess in 2 cases. Preoperative neurological function was assessed according to the American Spinal Injury Association (ASIA) classification: 1 case of grade B, 3 cases of grade C, 8 cases of grade D, and 17 cases of grade E. The disease duration was 6-48 months (mean, 19.3 months). All the patients were treated with posterior unilateral transpedicular or transarticular debridement with bone graft fusion and internal fixation under general anesthesia. Pre- and post-operative visual analogue scale (VAS) score, Oswestry disability index (ODI), and sagittal Cobb angle were recorded and compared. Bridwell classification standard was used to evaluate bone graft fusion. According to the number and the center of the lesion, the necessity to placement of titanium mesh cage was analyzed. Results All the patients were followed up 18-30 months (mean, 24 months). Cerebrospinal fluid leakage occurred in 3 cases, intercostal neuralgia in 2 cases, wound unhealed and fistula formation in 1 case, and ofiliac fossa abscess recurred in 1 case, and all recovered after symptomatic treatment. During follow-up, no fracture or loosing of internal fixation was found and all the lesions were cured at last follow-up. According to Bridwell classification standard, bone graft achieved bony fusion during 4-9 months after operation. The VAS score, ODI, and Cobb angle at immediate after operation and at last follow-up were significantly improved when compared with preoperative ones (P<0.05). At last follow-up, the neural function of all patients improved significantly when compared with preoperative one (Z= –3.101, P=0.002). The ratio of no placement of titanium mesh cage was significantly higher in patients with more than 6 lesion segments (6/6, 100%) than in patients with less than 6 lesion segments (4/23, 17.4%) (χ2=14.374, P=0.000). And the ratio of placement of titanium mesh cage was not significantly different between the patients with the different locations of center focus (χ2=0.294, P=0.863). Conclusion For treating multiple segments of thoracolumbar tuberculosis, the method of posterior unilateral debridement with bone graft and internal fixation can decrease the damage of posterior spinal structures and surgical trauma.
ObjectiveTo explore the safety and feasibility of the uncinate-process-first superior mesenteric artery (SMA) right posterior approach in laparoscopic pancreaticoduodenectomy (LPD).

The operative time was (366±51) min, the intraoperative blood loss was (140±42) mL, and the postoperative hospital stay was (11±2) days. All the postoperative pathological findings reached R0 resection. None of the 5 patients suffered from biliary leakage, bleeding, or gastrointestinal empties, and 2 patients suffered from biochemical fistula, the postoperative follow-up time was (7±2) months, and there was no recurrence during the follow-up period. ConclusionThe uncinate-process-first SMA right posterior approach is a safe and feasible surgical approach, especially for tumors with no obvious vascular invasion and diameter ≤2 cm.
ObjectiveTo investigate the surgical outcome of combined posterior and anterior approaches for the resection of thoracolumbar spinal canal huge dumbbell-shaped tumor. MethodsBetween January 2009 and March 2015, 12 patients with thoracolumbar spinal canal huge dumbbell-shaped tumor were treated by posterior approach and anterolateral approach through diaphragmatic crura and thoracoabdominal incision for complete resection. There were 9 males and 3 females, with an average age of 45 years (range, 30-65 years). The disease duration was 8-64 weeks (mean, 12.7 weeks). The tumor was located at T12, L1 in 6 cases, at L1, 2 in 5 cases, and at L2, 3 in 1 case. The tumor size ranged from 4.3 cm×4.0 cm×3.5 cm to 7.5 cm×6.3 cm×6.0 cm. According to tumor outside the spinal involvement scope and site and based on the typing of Eden, 5 cases were rated as type b, 2 cases as type d, 4 cases as type e, and 1 case as type f in the transverse direction; two segments were involved in 8 cases, and more than two segments in 4 cases. The degree of tumor excision, tumor recurrence, and the spine stability were observed during follow-up. The verbal rating scale (VRS) was used to evaluate pain improvement. ResultsThe average surgical time was 170 minutes (range, 150- 230 minutes); the average intraoperative blood loss was 350 mL (range, 270-600 mL). All incisions healed by first intention, and no thoracic cavity infection and other operation related complication occurred. Of 12 cases, 10 were histologically confirmed as schwannoma, and 2 as neurofibroma. The patients were followed up 6 months to 6 years (mean, 31 months). Neurological symptoms were significantly improved in all patients, without lower back soreness. The thoracolumbar X-ray film and MRI showed no tumor residue. No tumor recurrence, internal fixator loosening, scoliosis, and other complications were observed during follow-up. VRS at last follow-up was significantly improved to grade 0 (10 cases) or grade I (2 cases ) from preoperative grade I (2 cases), grade II (8 cases), and grade III (2 cases) (Z= —3.217, P=0.001). ConclusionCombined posterior approach and anterolateral approach through diaphragmatic crura and thoracoabdominal incision for complete resection of thoracolumbar spinal canal huge dumbbell-shaped tumor is feasible and safe, and can protect the stability of thoracolumbar spine and paraspinal muscle function. It can obtain satisfactory clinical result to use this method for treating the complex type of thoracolumbar spinal canal dumbbell-shaped tumor.
ObjectiveTo explore the therapeutic effect of gasless endoscopic thyroidectomy via axillary posterior approach for unilateral papillary thyroid microcarcinoma. MethodsThe clinicopathologic data of patients with unilateral papillary thyroid microcarcinoma who were treated by gasless endoscopic thyroidectomy via axillary posterior approach (observation group) or breast approach (control group) in the Xuzhou Central Hospital from January 2020 to February 2022 were collected. The operation time, accidental intraoperative bleeding, exposure time of recurrent laryngeal nerve, number of lymph node dissection, total hospital stay, and postoperative complications such as superior laryngeal nerve injury, cough due to drinking, temporary hoarseness, transient hypocalcemia, tunnel hematoma, and neck discomfort were compared between the two groups. Meanwhile, the cosmetic effects of the two groups were evaluated. ResultsA total of 87 patients who met the study conditions were enrolled in this study, including 47 cases in the observation group and 40 cases in the control group. There were no statistical differences in the baseline data such as gende, age, maximum tumor diameter, location of tumor, etc. between the two groups (P>0.05). Compared with the control group, the exposure time of recurrent laryngeal nerve was shorter (P<0.001) and the number of lymph node dissection was more (P=0.034), but the accidental intraoperative bleeding during operation was more (P=0.015) in the observation group. There were no statistical differences in the operation time and total hospital stay between the two groups (P>0.05). There were no superior laryngeal nerve injury and cough due to drinking in the two groups after operation, and there were no statistical differences between the two groups in the terms of postoperative temporary hoarseness, transient hypocalcemia, and tunnel hematoma (P>0.05), but it was found that the incidence of postoperative neck discomfort in the observation group was lower than that in the control group (P=0.043), and the postoperative cosmetic satisfaction score was also higher than that in the control group (P<0.001). ConclusionsFrom the results of this study, gasless endoscopic thyroidectomy via axillary posterior approach for unilateral papillary thyroid microcarcinoma is safe and feasible. It can quickly expose the recurrent laryngeal nerve and greatly improve the efficiency of lymph node dissection, as well as the cosmetic effect is better.
ObjectiveTo evaluate the effectiveness and safty of posterior popliteal fossa S-shaped incision with double-window approach for the treatment of posterior column of tibial plateau fractures.MethodsA retrospective analysis was made on the clinical data of 13 patients with complex tibial plateau fractures involving both posteromedial and posterolateral columns between May 2015 and July 2017. There were 9 males and 4 females, aged 33-64 years (mean, 46.5 years). The causes of injury included traffic accident in 5 cases, falling from height in 2 cases, falling from electric bicycle in 4 cases, and falling because of skiing in 2 cases. The preoperative range of motion of the affected knees was (35.1±9.2)°. The time from injury to surgery was 7-19 days (mean, 13.3 days). All patients underwent a posterior popliteal fossa S-shaped incision through the window of medial heads of gastrocnemius muscle (medial window) and the window between medial and lateral head of gastrocnemius muscle (popliteal fossa window) approaches. After a good visual control of fracture reduction, both posteromedial and posterolateral columns of tibial plateau fractures were fixed with buttress plate respectively. Bone union, limb alignment, articular surface, and range of motion were estimated after operation. The American Hospital for Special Surgery (HSS) score was used to evaluate functional outcomes of knees.ResultsAfter operation, 1 patient had fat liquefaction and dehiscence of incision, which healed after expanding the wound; the other patients’ incisions healed by first intention, and no vascular or nerve injury occurred during operation. All the 13 patients were followed up 12-18 months (mean, 16 months). The X-ray films showed that all patients obtained good fracture unions, the fracture healing time was 14-22 weeks (mean, 18 weeks). At 12 months after operation, the articular surface was smooth without collapse, and the knee range of motion was (109.5±13.6)°, showing significant difference when compared with preoperative value (t=18.879, P=0.000). No complication of infection, re-displacement of fracture, or secondary varus/valgus deformity was observed during follow-up. The HSS score was 82-96 (mean, 89.6) at 12 months after operation, with the result of excellent in 10 cases and good in 3 cases.ConclusionThe posterior column fracture of tibial plateau involving both posteromedial and posterolateral columns treated by double-window approach through posterior popliteal fossa S-shaped incision is safe and effective, with satisfactory results and good recovery of knee joint function.
Objective To explore the advantage of reconstruction belt for treating complicated acetabular fracture by combined anterior and posterior approaches through the comparison with reconstruction plate. Methods A retrospective analysis was made on the clinical data of 39 patients with acetabular fractures who met the selection criteria. After open reduction by combined anterior and posterior approaches was performed, fracture was fixed by reconstruction belt in 20 cases (trial group), and by reconstruction plate in 19 cases (control group). There was no significant difference in gender, age, cause of injury, time from injury to hospital, type of fracture, and preoperative visual analogue scale (VAS) score between 2 groups (P > 0.05). The number of plate shaping, plate shaping time, operation time, bleeding amount, perspective times, VAS score, modified Merled’Aubigne-Postel hip score, and related complications were recorded and compared. According to Matta standard, the fracture displacement was measured to evaluate the fracture reduction and fracture healing. Results The number of plate shaping, plate shaping time, operation time, bleeding amount, and perspective times in the trial group were significantly less than those in the control group (P < 0.05). The patients were followed up 12-29 months (mean, 21.1 months) in the trial group, and 12-27 months (mean, 20.5 months) in the control group. The VAS score was significantly lower at 7 days and 6 months after operation than at pre-operation, and at 6 months than at 7 days in 2 groups (P < 0.05), but difference was not significant between 2 groups (P > 0.05). At 6 months after operation, the Merled’Aubigne-Postel score of hip function in the trial group was 15.950±1.504, showing no significant difference when compared with the control group (15.895±1.629) (t= -0.110, P=0.913). The fracture displacement was (0.750±1.070) mm in the trial group and was (0.842±1.068) mm in the control group, showing no significant difference (t= -0.269, P=0.789). The X-ray films showed that all fractures healed in 2 groups. The healing time was (16.10±2.07) weeks in the trial group and was (15.84±2.14) weeks in the control group, showing no significant difference (t =0.382, P=0.075). Conclusion Reconstruction belt for complicated acetabular fracture by combined anterior and posterior approaches has similar effectiveness to reconstruction plate, but the number of plate shaping, plate shaping time, and perspective times are fewer.
