Objective To review the progress of surgical treatment for the thoracolumbar spinal tuberculosis. Methods The related literature of surgical treatment for the thoracolumbar spinal tuberculosis was reviewed and analyzed from the aspects such as surgical approach, fixed segments, fusion ranges, bone graft, and bone graft material research progress. Results Most scholars prefer anterior or combined posterior approach for surgical treatment of thoracic and lumbar tuberculosis because it possessed advantage of precise effectiveness. In recent years, a simple posterior surgery achieved satisfactory effectiveness. The fixation segments are mainly composed of short segments or intervertebral fixation. The interbody fusion is better for the bone graft fusion range and manner, and the bone graft materials is most satisfied with autologous iliac Cage or titanium Cage filled with autologous cancellous bone. Conclusion The perfect strategy for treating the thoracolumbar spinal tuberculosis has not yet been developed, and the personalized therapy for different patients warrants further study.
ObjectiveTo compare the clinical and radiographic results between primary total knee arthroplasty (TKA) via mini-subvastus or conventional approach through a prospective randomized controlled study.MethodsNinety-four patients (104 knees) undergoing primary TKA between January 2011 and April 2012 were evaluated and randomly divided into 2 groups. Forty-six patients (52 knees) underwent TKA via conventional approach (conventional approach group), and 48 patients (52 knees) underwent TKA via mini-subvastus approach (mini-subvastus approach group). In these patients, 45 cases (51 knees) in conventional approach group and 45 cases (49 knees) in mini-subvastus approach group were followed up and recruited in the final analysis. There was no significant difference in age, gender, body mass index, sides, osteoarthritis grading, American Knee Society Score (KSS), Hospital for Special Surgery (HSS) score, visual analogue scale (VAS), range of motion (ROM) of knee between 2 groups (P>0.05). The clinical indexes were recorded and analyzed, including the operation time, length of incision, total blood loss, blood transfusion after operation, hospital stay time, the time of performing straight leg raise, incision condition, VAS score, ROM of knee, HSS score, and KSS score, hip-knee-ankle angle (HKA), femoral anatomic axis and the femoral prosthesis joint angle (femoral angle), tibia anatomic axis and tibial prosthesis joint angle (tibial angle), femoral prosthesis flexion angle (FPFA), and posterior slope angle (PSA) of the tibial plateau.ResultsAll patients were followed up. The average follow-up time was 66.4 months (range, 60.0-72.5 months) in conventional approach group and 65.6 months (range, 60.0-71.2 months) in mini-subvastus approach group. Compared with the conventional approach group, the incision of mini-subvastus approach group shortened, the operation time prolonged, and the time when patients started straight leg raise exercises was earlier; showing significant differences between 2 groups (P<0.05). There was no significant difference in hospital stay time, total blood loss, and numbers of blood transfusion between 2 groups (P>0.05). The complication rate was 8.2% (4/49) in mini-subvastus approach group and 0 in conventional approach group, showing no significant difference between 2 groups (P=0.054). At 1 and 3 days, the VAS and the ROM of knee in mini-subvastus approach group were significantly better than those in conventional approach group (P<0.05); but there was no significant difference in above indexes between 2 groups at 14 day (P>0.05). There was no significant difference in HSS and KSS scores between 2 groups at the 1, 3, 6, 12 months and 3, 5 years (P>0.05). X-ray film showed no aseptic loosening in all cases. There was no significant difference in the measured values and incidence of abnormal patient of HKA, femoral angle, tibial angle, FPFA, and PSA at last follow-up between 2 groups (P>0.05).ConclusionTKA via mini-subvastus approach is helpful to the early function recovery of knee, but the long-term effectiveness is consistent with TKA via conventional approach. As the limited exposure, TKA via mini-subvastus spproach may has high risk of operative complications.
ObjectiveTo compare the effectiveness between paratricipital approach and chevron olecranon V osteotomy approach for the treatment of type C3 (AO/OTA) distal humeral fractures and investigate the details of operation.MethodsBetween April 2010 and September 2016, 36 type C3 (AO/OTA) distal humeral fractures were treated with open reduction and bicolumnar orthogonal locking plating fixation by paratricipital approach and chevron olecranon V osteotomy approach respectively. The patients were divided into 2 groups by approach, there were 17 cases in paratricipital group (group A) and the bicolumns and distal humeral joint surface were exposed by traction of triceps and olecranon, and the distal humeral joint surface of the 19 cases in chevron olecranon V osteotomy group (group B) were exposed by osteotomy of the olecranon and reversing of triceps. There was no significant difference in gender, age, dominant side, interval between injury and surgery, causes of injury between 2 groups (P>0.05). Patients were followed up, the postoperative range of motion of elbow joint, strength, pain, and stability in 2 groups were documented and compared; the elbow joint function was evaluated according to Mayo elbow performance score (MEPS).ResultsThe operation time of group A [(115.0±10.4) minutes] was less than that of group B [(121.0±12.3) minutes], but there was no significant difference (t=–1.580, P=0.123). All patients in 2 groups got over 1 year follow-up and there was no significant difference of the follow-up time between 2 groups (t=–0.843, P=0.405). There was 1 case of heterotopic ossification in each group; 1 case of incision infection in group A and 1 case of incision superficial infection in group B, and were cured after 2 weeks of intravenous antibiotics administration. There was no other operative complications in the 2 groups. At 3 months after operation, all the distal humerus healed. At last follow-up, the elbow flexion extension range of groups A and B were (102.0±12.6)° and (99.5±10.1)° respectively, showing no significant difference (t=–0.681, P=0.501). The MEPS scores of groups A and B were 82.9±7.3 and 81.3±7.2 respectively, showing no significant difference (t=0.670, P=0.507); and the evaluation grade also showed no significant difference between 2 groups (Z=–0.442, P=0.659).ConclusionBy paratricipital approach and proper traction of the olecranon, the distal humeral articular surface can be exposed in the operation of type C3 distal humeral fractures, followed with same stable fixation after reduction, the effectiveness is equal to by chevron olecranon V osteotomy approach.
ObjectiveTo evaluate the long-term effectiveness of patients received surgical treatment under the guidance of “West China Classification” of desmoid-type fibromatosis (DTF) in the shoulder girdle.MethodsThe clinical data of 32 patients with DTF in the shoulder girdle admitted between June 2003 and December 2016 were retrospectively analyzed, including 14 males and 18 females, aged 14-56 years with an average age of 36.8 years. The maximum diameter of the tumor was 7-19 cm, with an average of 11.1 cm. According to the “West China Classification” of DTF in the shoulder girdle, there were 4 cases of region Ⅰ, 3 cases of region Ⅱ, 6 cases of region Ⅲ, 3 cases of region Ⅳ, 5 cases of regions Ⅰ+Ⅱ, 5 cases of regions Ⅱ+Ⅲ, and 6 cases of regions Ⅰ+Ⅱ+Ⅲ. In addition, the involvement of blood vessels and nerves was also taken into consideration for choosing a surgical approach. Finally, 12 cases were operated via anteroposterior approach (group A), 14 via posterior approach (group B), and 6 via combined anterior-posterior approach (group C). The 1993 Musculoskeletal Tumor Society (MSTS93) score (including pain, limb function, satisfaction, hand position, hand flexibility, and lifting ability), Japanese Orthopedic Association (JOA) score, range of motion (ROM) of shoulder joint (including flexion, extension, abduction, and adduction), and complications of patients in the 3 groups were recorded and compared.ResultsAll the 32 patients were followed up 30-190 months, with an average of 94.6 months. At last follow-up, complications occurred in 5 cases (15.6%), including 2 cases (16.6%) in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. There was no significant difference in the incidence of complications among the 3 groups (P=1.000). Tumor recurrence occurred in 5 (15.6%) cases, including 1 (8.3%) case in group A, 2 (14.3%) in group B, and 1 (16.6%) in group C. No significant difference was found in the recurrence rate among the 3 groups (P=1.000). At last follow-up, MSTS93 score of pain, limb function, satisfaction, hand flexibility, and hand position in groups A and B were significantly better than those in group C (P<0.05), even though no significant difference existed between group A and group B (P>0.05). The lifting ability score in group C was significantly lower than in group A (P<0.05), and no significant difference was found between other groups (P>0.05). The JOA score and flexion, extension, abduction, and adduction activities of shoulder in groups A and B were significantly better than those in group C (P<0.05). The extension activity in group A was significantly better than that in group B (P<0.05), the flexion activity in group B was significantly better than that in group A (P<0.05). There was no significant difference in other indexes between groups A and B (P>0.05).ConclusionTaking a rational approach to fully expose and completely remove the tumor is the key point of surgical treatment for patients with DTF in the shoulder girdle. At the same time, preservation of vital structures and reconstruction of soft tissues should also be taken into consideration. Overall, surgical treatment under the guidance of “West China Classification” of DTF in the shoulder girdle has achieved satisfactory long-term effectiveness.
ObjectiveTo compare the short-term effectiveness and safety of unipedicular versus bipedicular percutaneous kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF) with posterior wall broken.MethodsThe clinical data of 68 patients with OVCF with posterior wall broken and without posterior ligament complex injury and spinal cord nerve injury between June 2013 and December 2018 were retrospectively analyzed. According to the different operative approaches, the patients were divided into two groups: group A (36 cases received PKP via bilateral pedicle puncture) and group B (32 cases received PKP via unilateral pedicle paracentesis). There was no significant difference between the two groups in gender, age, fracture vertebra distribution, time from injury to operation, preoperative pain visual analogue scale (VAS) score, Oswestry disability index (ODI), and height of injured vertebra (P>0.05). The operation time, intraoperative fluoroscopy times, and bone cement volume were recorded and compared between the two groups. The VAS score and ODI score were used to evaluate the effectiveness before operation, at 1 day and 6 months after operation; the height of injured vertebra was measured on the lateral X-ray film, and the recovery height of injured vertebra at 1 day after operation and the loss height of injured vertebra at 6 months after operation were calculated; the intraoperative and postoperative complications of the two groups were recorded.ResultsThe operation time, intraoperative fluoroscopy times, and bone cement volume of group B were significantly less than those of group A (P<0.05). All patients were followed up 10-35 months, with an average of 18 months. During the operation, there were 2 cases (5.56%) of cement leakage in group A and 9 cases (28.13%) in group B, showing significant difference (χ2=4.808, P=0.028). There was no adverse reactions of bone cement, iatrogenic spinal cord injury, infection of puncture port, or other complications in the two groups. During the follow-up period, there were 3 cases (8.3%) of adjacent vertebral fractures in group A and 2 cases (6.3%) in group B, showing no significant difference between the two groups (χ2=0.027, P=0.869). The height of injured vertebra of the two groups at 1 day and 6 months after operation were significantly improved when compared with preoperative ones (P<0.05). There was no significant difference in the height of injured vertebrae and the recovery height of injured vertebra at 1 day after operation between the two groups (P>0.05). However, at 6 months after operation, the height of injured vertebra in group B was significantly lower than that in group A (P<0.05), and the loss height of injured vertebra in group B was significantly higher than that in group A (P<0.05). The VAS score and ODI score at 1 day and 6 months after operation were significantly improved when compared with preoperative ones in both groups (P<0.05), but there was no significant difference between the two groups (P>0.05).ConclusionBoth bipedicular and unipedicular PKP can obtain satisfactory effectiveness for the treatment of OVCF with posterior wall broken, but the former may have advantages of lower cement leakage rate and less height loss.
ObjectiveTo investigate the effectiveness of treatment of locked lower cervical fracture and dislocation with anterior cervical fusion and internal fixation combined with the release of the interlocking facet through the Luschka joint and anterior lamina space.MethodsTwelve patients with lower cervical interlocking fracture and dislocation were analyzed retrospectively between January 2013 and June 2015. There were 7 males and 5 females, aged 25-59 years with an average age of 38.4 years. The disease duration was 9.6 hours to 100 days with an average of 7.3 days. There were 8 cases of unilateral locking and 4 cases of bilateral locking; 4 cases of old injury and 8 cases of fresh injury. The injured segments were 2 cases of C3, 4, 5 cases of C4, 5, 3 cases of C5, 6, and 2 cases of C6, 7. According to Meyerding classification, there were 9 cases of grade Ⅰ and 3 cases of grade Ⅱ. According to the functional classification of American Spinal Injury Association (ASIA), there were 2 cases of grade C, 6 cases of grade D, and 4 cases of grade E. The interlocking facet was released through the Luschka joint and anterior lamina space, and the anterior cervical fusion and internal fixation were used to treat the fracture and dislocation of the lower cervical spine. The recovery of spinal cord function was judged by the functional classification of ASIA; visual analogue scale (VAS) score, neck disability index (NDI) score, modified Japanese Orthopaedic Association (m-JOA) score were used to evaluate the clinical efficacy; the Cobb angle of fusion segment were observed by X-ray film. The intervertebral bone graft fusion was evaluated at 6 months after operation.ResultsThe average operation time was 78.30 minutes, the average intraoperative blood loss was 167.30 mL, and the average postoperative drainage volume was 58.12 mL. No blood transfusion was given during or after operation. During the operation, there was no accidental injury of large blood vessels, esophagus, and trachea; no laryngo edema, dysphagia, hoarseness, and cerebrospinal fluid leakage occurred after operation; no spinal cord injury or nerve root injury aggravated; the incision healed by first intention, and no infection occurred. All 12 cases were followed up 15-20 months, with an average of 16.5 months. The symptoms and function of the nerve injury were significantly improved when compared with that before operation. Re-examination of the cervical spine X-ray film at 6 months after operation showed that the Cage or bone graft was not displaced or broken, the screw was not loosened or detached, and the intervertebral graft fusion rate was up to 100%. At last follow-up, the ASIA grade, Cobb angle of fusion segment, neck pain VAS score, m-JOA score, and NDI score were significantly improved when compared with preoperative one (P<0.05).ConclusionThe effectiveness of treatment of locked lower cervical fracture and dislocation with anterior cervical fusion and internal fixation combined with the release of the interlocking facet through the Luschka joint and anterior lamina space is clear, which not only can make the injured segment get satisfactory reduction, immediate stability and reconstruction, and full decompression, but also can effectively prevent the secondary injury of spinal cord.
ObjectiveTo investigate the effectiveness of the extended Carlson approach in the treatment of lateral femoral condylar Hoffa fractures.MethodsThe clinical data of 17 patients with lateral femoral condyle Hoffa fractures between September 2012 and January 2019 were retrospectively analyzed. There were 10 males and 7 females, with a mean age of 43 years (range, 32-68 years). Fractures were caused by traffic accident in 9 cases, by falling from height in 6 cases, and by the other mechanism in 2 cases. According to the Letenneur’s classification, there were 8 cases of typeⅠ, 6 cases of type Ⅱ, and 3 cases of type Ⅲ. The mean time from injury to operation was 7 days (range, 3-32 days). All patients were treated with extended Carlson approach. Patients with Letenneur types Ⅰ and Ⅲ were fixed by a posterior antigliding plate combined with headless compression screws from anteroposterior direction, and patients with Letenneur typeⅡ were fixed by headless compression screws from anteroposterior direction. The anteroposterior and lateral X-ray films, CT and three-dimensional reconstruction of the knee joint were taken after operation to assess fracture healing and position of the internal fixators. The knee function was evaluated according to Letenneur’s functional assessment system.ResultsAll patients were followed up 13-28 months (mean, 15 months). All the incisions healed by first intention, and no complication such as fracture redisplacement, fracture nonunion, internal fixator fracture, and common peroneal nerve injury occurred. The mean time of fracture healing was 18 weeks (range, 16-32 weeks). At last follow-up, according to Letenneur’s functional assessment system, the knee function was excellent in 12 cases and good in 5 cases, with an excellent and good rate of 100%.ConclusionThe extended Carlson approach for the treatment of lateral femoral condylar Hoffa fractures has the advantages of clear exposure, easy reduction and fixation, high fracture healing rate, few complications, and good recovery of knee joint function.
ObjectiveTo review the research progress of different surgical approaches in the treatment of acetabular both-column fractures.MethodsThe domestic and foreign related research literature on surgical approaches for acetabular both-column fractures was extensively consulted. The anatomical characteristics, exposure ranges, advantages, disadvantages, and indications of various common surgical approaches for both-column fractures were mainly summarized.ResultsThe ilioinguinal approach is more suitable for both-column fractures if the anterior column fracture is complicated or combined with the anterior wall fracture while the posterior column fracture is simple and stable. The modified Stoppa approach or the lateral (para) rectus abdominal approach is the preferred choice when both-column fractures are combined with a quadrilateral fracture or femoral head dislocation. What’s more, the Kocher-Langenbeck approach is required when the posterior column fractures are complicated or combined with posterior wall fractures. In addition, the simultaneous ilioinguinal and Kocher-Langenbeck approaches are the first choices when the both-column fractures possessing extremely severe and obvious displacement.ConclusionThe reasonable choice of surgical approach is extremely important for acetabular both-column fractures. Each surgical approach has its advantages and limitations. It is necessary to take the precise reposition of the acetabular joint surface as the principle, and comprehensively judge the fracture types and severity of anterior column, posterior column, and square area, and then select the optimal surgical approach for surgical treatment.
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.
ObjectiveTo summarize the advantages and disadvantages of different surgical approaches in thyroidectomy using the da Vinci robotic surgical system. MethodThe relevant to articles about da Vinci robotic thyroidectomy via different surgical approaches at home and abroad were retrieved and reviewed. ResultsThe robot-assisted transaxillary thyroidectomy had a definite curative effect and was a mature technology. The bilateral axillary-breast approach thyroidectomy had a wide range of applications and was suitable for beginners. The robotic retroauricular approach thyroidectomy had great advantages in the dissection of lateral cervical lymph nodes. The transoral robotic thyroidectomy was a surgical approach that conformed to the minimally invasive concept. Conclusions Da Vinci robotic thyroidectomy via different surgical approaches has its corresponding application scope and advantages. Clinical surgeons should choose an optimal surgical approach according to the tumor location, size and number of patients and the advantages of the operator, so as to achieve the therapeutic effect of radical cure of tumors and reduction of injury.
