Objective To measure the anatomical parameters related to lumbar unilateral transverse process-pedicle percutaneous vertebral augmentation, and to assess the feasibility and safety of the approach. Methods A total of 300 lumbar vertebral bodies of 60 patients were randomly selected, and vertebral augmentation were simulated 600 times on X-ray and CT image with unilateral conventional transpedicle approach (control group) and unilateral transverse process-pedicle approach (experimental group). The distance between the entry point and the midline of the vertebral body, the puncture inner inclination angle, the safe range of the puncture inner inclination angle, and the puncture success rate were measured and compared between the left and right with the same approach, and between the two approaches. Results The distance between the entry point and the midline gradually increased from L1 to L5 on both sides in the 2 groups. In the control group, the right sides distance of L1 and L2 was much longer than the left sides, and the right sides distance of L1, L2, and L5 was much longer than the left sides in the experimental group (P<0.05); the distance of the experimental group between the entry point and the midline was much longer than the control group regardless of the sides from L1 to L5 (P<0.05). In the experimental group, the right maximum inner inclination angle from L1 to L5, the right middle inner inclination angle from L1 to L5, and the right minimum inner inclination angle from L1, L2, L4, L5 were significantly larger than the left side (P<0.05). The maximum inner inclination angle and the middle inner inclination angle presented increased tendency, the tendency of minimum inner inclination angle was ambiguous, however, the all inner inclination angles were much larger than those in control group among the different lumbar levels(P<0.05). There was no significant difference of the safe range of the puncture inner inclination angle between 2 sides in 2 groups at L1 to L5 (P<0.05); the safe range angle in experimental group at L5 was significantly smaller than that in control group (P<0.05). The difference in total puncture success rate of all lumbar levels was significant between the experimental group and the control group (χ2=172.252, P=0.000); the puncture success rates of the experimental group were higher than those in the control group form L1 to L4 (P<0.05), but no significant difference was found in the puncture success rate between 2 groups at L5 (P>0.05). Conclusion Compared with the unilateral conventional transpedicle approach, the entry point of the unilateral transverse process-pedicle approach is localized outside, the puncture inclination angle is wider, and the puncture success rate is higher. It shows that the unilateral transverse process-pedicle approach is safer and more reliable than the unilateral conventional transpedicle approach.
Objective To investigate a new surgical approach for presacral lesion by double door via S3- 5. Methods From June 2007 to January 2008, 5 female patients (56-84 years old) with presacral lesion were treated. One patient had straining feel ing in anus, 2 patients had difficult defecation and bloody stool and 2 patients had no symptoms. Digital rectal examination revealed rectal tumor in 2 cases and anus examination of presacral tumor showed no abnormal ity in 3 cases. B-ultrasound, CT and MRI examination displayed presacral tumor in 3 cases and rectumal tumor in 2 cases. The size ofthe lesions was 4 cm × 3 cm × 3 cm - 20 cm × 15 cm × 13 cm. The disease course was 12-50 days (average 18 days). All 5 patients received total resection of tumor through the surgical approach featured by double door via S3-5. Results The operations were successful in all the 5 patients, and no severe presacral venous hemorrhage, rectal injury, direct injury of pelvic nerve and structure damage of pelvic bottom occured during operation. The approach exposure time was 12-28 minutes (average 20 minutes) and the blood loss for approach was 30-130 mL (average 80 mL); and the operation time was 80-120 minutes (average 105 minutes) and the blood loss during operation was 100-350 mL (average 280 mL). All incision healed by first intention. Pathological examination of resected tissue after operation revealed presacral teratoma in 1 case, dermoid cyst in 1 case, spindle cell tumor in 1 case and rectal tubiform villus adenoma in 2 cases. All the patients suffered from perineal hypoesthesia to various degrees after operation, which were recovered to the normal 6 months later, and X-ray films showed bone union occurred in all the cases. No gatism occured. During the followed-up period of 6-13 months, no sacrum defect, pelvic instabil ity and sacroil iitis was observed in the 5 cases. B-ultrasound, CT and MRI examination showed no recurrence of tumor. Conclusion The approach of double door via S3-5 is a simple and safe surgical procedure featured by a good surgical exposure with less bleeding, short operative time, no sacrum defect, no severe sacral nerve damage, and early postoperative convalescence.
ObjectiveTo analyze the clinical outcomes of extended thymectomy for myasthenia gravis (MG) patients under different surgical approaches, and to determine the factors affecting the prognosis of MG. MethodsThe MG patients who underwent extended thymectomy from January 2014 to March 2021 in our hospital were retrospectively collected. According to the surgical approach, they were divided into a subxiphoid group and an intercostal group, and the perioperative results and prognosis were compared between the two groups. A “good outcome” was defined as complete stable remission (CSR), pharmacological remission (PR) or minimal manifestations state (MMS); a “poor outcome” was defined as outcomes worse than MMS. Univariate and multivariate logistic regression analyses were performed to assess the factors associated with the good outcomes. ResultsA total of 187 MG patients were included in the study, including 82 males and 105 females, with a median age of 50 (36, 60) years. There were 134 patients in the intercostal group and 53 patients in the subxiphoid group. Compared with the intercostal group, although the operation time of the subxiphoid group was longer [200.0 (172.0, 232.0) min vs. 141.0 (118.0, 169.0) min, P<0.001], the intraoperative blood loss was less [10.0 (10.0, 20.0) mL vs. 20.0 (10.0, 50.0) mL, P<0.001], the postoperative hospital stay was shorter [3.0 (2.5, 4.0) d vs. 5.0 (3.0, 7.0) d, P<0.001], and the incidence of complications was lower [1 (1.9%) vs. 26 (19.4%), P=0.001]. A total of 159 (85.0%) patients were followed up for a median period of 46 (13, 99) months, with a good outcome rate of 90.6% and CSR rate of 33.3%. There were no statistical differences in PR, MMS or overall good outcome rates between the two groups (P>0.05). Multivariate logistic analysis showed that age≤50 years was an independent predictor for "good outcome" of MG patients. ConclusionExtended thymectomy via subxiphoid for MG is a safe, feasible and effective surgical approach.
Objective To discuss the optimal approach to treat suprascapular nerve compression syndrome. Methods From January 2000 to June 2003, 8 cases of suprascapular nerve compression syndrome were treated by surgical intervention to cut the transverse scapular ligament through posterior approach. Of the 8 patients, there were 2 males and 6 females (age ranged from 21 to 53) with duration of 6 months to 3 years. The change of symptom, muscle power, and muscle atrophy after operation were observed. Results One week after operation, pain around the scapular disappeared, muscle power of supraspinatus and infraspinatus muscles recovered to normal. One, 6, 12 and 16 months after the operation, the patients were followed up. No recurrence was observed. Muscle atrophy didn’t recover.Conclusion To treat suprascapular nerve compression syndrome with operation through posterior approach is easy to operate. When the suprascapular nerve is entrapped in scapular notch, this approach is a good choice.
Objective To summarize the development of endoscopic thyroid surgery and expound the advantages and disadvantages. Method Reviewed the domestic and foreign literatures on different ways of endoscopic thyroid surgery. Results Gagner tried accomplish subtotal parathyroidectomy with endoscope at the first time in 1996. And then, Hüscher improved the endoscope technology and applied on thyroidectomy in 1997. Henceforth, endoscopic thyroid surgery had developed rapidly, from small neck incision surgery, such as endoscopic assisted small neck incision thyroidectomy, to traceless neck surgery, such as thoraco mammary approach, areola approach, axillary approach, retroauricular approach, combined approach, etc., to traceless body surface skin surgery in recent years, such as natural cavity oral approach. Completed endoscopic surgery makes the incision scar hide or even disappear, which had attracted the attention and learning of thyroid specialist clinicians all over the world. The choice of patients was more and more broad and diverse, and all kinds of approaches had different advantages and disadvantages.Conclusions The advantages, disadvantages, indications and contraindications of various endoscopic approaches are different. According to the location differences of individual thyroid masses and the requirements for aesthetics, the most appropriate endoscopic thyroid approach is selected to achieve the optimal solution of manual approach.
From Jan. 1991 to Jan. 1994, 11 cases ofdifferent hip lesions with flexon contracture deformity were treated by combination of SmithPeterson and WatsonJones incisions in replacement of hip joint. All of them were followed-up for 1 to 3 years (an average of 1.9 years). According to pain, joint function, the excellent and good results were rated at 90.9%. This showed that from using the combined incisions, the hip joint was very well exposed, and release of hip flexion contracture could be acomplished in the same time. Bleeding fromoperation was reduced and the procedure was simple.

ObjectiveTo compare the clinical results of throacolumbar fractures treated through Wiltse paraspinal approach and conventional posterior approach. MethodsSeventy-six cases of single segmental thoracolumbar fractures (Type A) were treated by posterior reduction and pedicle screw instrumentation from January 2011 to January 2013. Thirty-five cases were treated through Wiltse paraspinal approach (group A), including 27 males and 8 females with an average age of 39.7 years. Forty-one cases were treated through conventional posterior approach (group B), including 30 males and 11 females with an average age of 41.6 years. The data including incision length, operation time, intraoperative blood loss, postoperative volume of drainage, the anterior vertebral height, Cobb angle and complications were compared between the two groups. ResultsAll operations were finished successfully. The incision length, operation time, intraoperative blood loss and postoperative volume of drainage were (8.3±1.9) cm, (74.0±21.9) min, (125.0 ±46.7) mL, and (51.0±42.6) mL respectively in group A, and (10.7±2.8) cm, (97.0±18.2) min, (245.0±56.1) mL, and (190.0±72.3) mL in group B respectively. There was significant difference between the two groups (P<0.05). The restoration of anterior vertebral height and the correction of Cobb angle were well maintained in both groups. The difference was statistically significant before and after treatment (P<0.05), but there was no significant difference between the two groups (P>0.05). There was no difference in the complication rate between the two groups (P>0.05). ConclusionCompared with conventional posterior approach, Wiltse paraspinal approach has the advantage of shorter operation time, less trauma and blood loss. It is a better option for the treatment of throacolumbar fractures.
Objective To review the research on different surgical approaches and MRI evaluation of total hip arthroplasty (THA), to clarify the possible muscle damage caused by different approaches, and to help clinicians avoid intraoperative muscle damage and identify the causes of certain muscle-related complications after operation. MethodsThe research literature on different surgical approaches and MRI evaluation of THA at home and abroad was extensively reviewed to summarize the MRI performance of the posterior approach, modified direct lateral approach, direct anterior approach, and minimally invasive anterolateral approach (also called Orthopadische Chirurgie Munchen approach). Results The traditional posterior approach mainly damages the short external rotator muscle group and increases the incidence of postoperative dislocation; the piriformis-keeping posterior approach significantly improves the quality of the pyriformis tendon in the postoperative period, but it may lead to damage to the intrapelvic portion of the piriformis muscle. The modified direct lateral approach mainly damages the gluteus medius muscle, which increases the risk of postoperative claudication. The direct anterior approach mainly damages the vastus tensoris muscle and may result in damage to the short external rotator muscle group and the muscles around the incision. The minimally invasive anterolateral approach primarily damages the superior gluteal nerve, which subsequently leads to denervation of the broad fascial tensor fasciae latae, and this approach may also result in injury to the gluteus medius and gluteus minimus muscles. The muscle damage status significantly affects prognosis, and the minimally invasive approach is more suitable for elderly patients. ConclusionMRI can clarify the different types of muscle damage caused by different surgical approaches. Minimally invasive approaches can reduce muscle damage and improve postoperative function compared with traditional approaches, and can benefit elderly patients more, but due to the small field, forcing to expand the surgical field will lead to unintended muscle damage and reduce postoperative function.
