Objective To evaluate the effect of anterolateral approach in treating thoracolumbar disc protrusion. Methods From May 2004 to May 2008, 11 patients with thoracolumbar disc protrusion (T10-L3) underwent discectomy, autologous il iac bone graft, and internal fixation via anterolateral approach. There were 9 males and 2 females aged 26-57 years old (average 42.8 years old). The course of disease was 1 week-11 years (average 2.7 years). Nine patients showed the lower l imbs weakness, 8 had sensory disturbance, 6 presented with lumbodorsal pain, 5 had the lower l imb pain, 4 presentedwith sphincter muscle disturbance, 3 suffered from foot drop, and 5 had a history of lower back injury. X-ray, CT, and MRI test showed that 9 cases had the single-segmental protrusion, 2 cases had double-segmental protrusion, 2 cases were accompanied with ossification of the thoracic vertebra yellow l igament, 2 cases were combined with ossification of the vertebra posterior longitudinal l igament, and 1 was compl icated with Scheuermann disease. Preoperatively, the intervertebral height was (7.2 ± 1.3) mm and JOA score was 6.4 ± 2.8. Results The time of operation was 2.5-5.5 hours (average 3.5 hours); the blood loss during operation was 500-1 200 mL (average 750 mL). During operation, intraoperative pleural tear occurred in 1 patient, peritoneal tear in 1 patient, and dural laceration in 1 patient. Repairing was performed intraoperative and preventive suction drainage was used for 3-5 days. No postoperative hydropneumothorax and cerebrospinal fluid leakage occurred. All incisions healed by first intention. No postoperative compl ications of nerve system occurred. All the patients were followed up for 1-4 years (average 2.4 years). X-ray films showed that all the patients achieved bony fusion without the occurrence breakage and loosening of titanium plate and screw 6-9 months after operation. Three cases displayed subtle scol iosis (10-15°) without influence on spinal equil ibration. The intervertebral height increased to (12.3 ± 1.5) mm 2 weeks after operation, indicating there was a significant difference compared with preoperative value (P lt; 0.05). The intervertebral height 1 year after operation when the bony fusion was reached decreased to (7.5 ± 1.2) mm, indicating there was no significant difference compared to the preoperative value (P gt; 0.05). The JOA score increased to 7.6 ± 3.2 at 1 year after operation, indicating there was a significant difference compared with preoperative value (P lt; 0.05). The symptoms and signs of all the patients were improved to various degrees after operation. According to improvement rate evaluation system proposed by Hirabayashi t al., 4 cases were graded as excellent, 6 as good, 1 as fair, and the excellent and good rate was 90.9%. Conclusion Treating thoracolumbar disc protrusion via anterolateral approach is safe and effective.
ObjectiveTo investigate the effectiveness of Tang’s arthroscopy approach in treatment of anterior and posterior ankle impingement syndrome.MethodsBetween August 2010 and September 2017, 92 patients with anterior and posterior ankle impingement syndrome were retrospectively analyzed. There were 58 patients were treated with Tang’s arthroscopy approach under floating decubitus (group A) and 34 patients were treated with standard anterior and posterior approaches (group B). There was no significant difference in gender, age, body mass index, side, disease duration, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score, and preoperative visual analogue scale (VAS) score between the two groups (P>0.05).The operation time, AOFAS score, VAS score, and Roles-Maudsley score were recorded to evaluated the pain and function of the ankle, and patient subjective satisfaction. The X-ray film and MRI at 12 months were used to observe the ankle impingement.ResultsMedian operation time of group A was 50.5 minutes ［95%CI (49.3, 54.6)］, which was significantly shorter than that of group B ［88.5 minutes, 95%CI (76.5, 92.8)］ (Z=−4.685, P=0.000). All incisions in group A healed by first intention; while the incisions of 2 cases in group B delayed healed after debridement. The follow-up time of group A was (54.7±18.8) months, while that of group B was (55.4±17.9) months, and there was no significant difference between the two groups (t=−0.178, P=0.859). The lateral X-ray films at 12 months showed that the talus process was removed incompletely in 2 cases (3.4%) of group A and 1 case (2.9%) of group B. There was no significant difference in the incidence between the two groups (χ2=0.014, P=0.699). At last follow-up, the AOFAS scores were 83.1±6.6 in group A and 85.2±6.4 in group B; the VAS scores were 1.3±1.1 in group A and 1.6±1.0 in group B. The AOFAS and VAS scores at last follow-up were superior to preoperative ones (P<0.05), but there was no significant difference between the two groups (P>0.05). The median subjective satisfaction score of group A was 2.0 ［95%(1.4, 1.7)］, which was better than that of group B ［2.0, 95%(1.6, 2.2)］ (Z=−2.480, P=0.013).ConclusionArthroscopic treatment of anterior and posterior ankle impingement syndrome through Tang’s approach can shorten the operation time, simplify the procedures, and obtain good effectiveness and patient satisfaction.
Objective To investigate the assembl ing and cl inical appl ication of the video output system util izing teaching sight glass of surgical microscope. Methods Between June 2009 and April 2010, 10 patients with craniocervical junction malformation were treated by the method of transoral-transpharyngeal approach with the microscope and videooutput system under the direct vision. There were 6 males and 4 females with an average age of 32 years (range, 13-52 years). Three cases had the history of injury and 7 cases had no history of definite injury. The disease duration was from 10 months to 12 years (median, 5 years). The main cl inical symptoms were brevicoll is or torticoll is; 2 patients had malformation appearance and 4 patients had occi put-cervical pain. The physical examination showed that all patients had the symptoms that upper cervical cord was damaged; the imaging examination showed that all patients had basilar invagination, atlantoaxial dislocation, and ossification. Before and after operations, the functions of nerve were evaluated by Japanese Orthopaedic Association (JOA) scoring, the improvement rate was calculated to evaluate the efficacy. Results By the video output system assembly, 15.1 mill ion pixels high-definition images could be collected and reached 1 920 × 1 080 pixels video camera, so assistants or medical students could watch the cl inical operation directly. All patients had no neural injury or cerebrospinal fluid leakage during operation. Basilar invagination and atlantoaxial dislocation were corrected. Infection at incision occurred in 1 patient; other incisions healed by first intention without early compl ication. All patients were followed up 6-16 months (mean, 13.5 months). The average JOA score was increased from 10.2 preoperatively to 15.5 at 6 months postoperatively with an improvement rate of 77.9%. At 12 months after operation, bony fusions were achieved. Conclusion The miscroscope and video output system can improve the effectiveness of the original surgical microscope. It makes visual fields much clearer and operations more accuratewith a few compl ications.
ObjectiveTo investigate the effectiveness of modified Stoppa approach with medial wall spring plate (MWSP) for involving quadrilateral of acetabulum fracture. MethodsBetween March 2008 and September 2013, 38 patients with involving quadrilateral of acetabulum fracture were treated, including of 23 males and 15 females with an average age of 36.08 years (range, 19-56 years). The causes included traffic accidents injury (21 cases), crash injury of heavy object (10 cases), and falling injury from height (7 cases). The interval of injury and admission was 3 hours to 2 days (mean, 11 hours). There were 12 cases of anterior column fracture (type D), 5 cases of transverse fractures (type E), 8 cases of T shaped fractures (type H), 6 cases of anterior column fracture with posterior transverse fractures (type I), and 7 cases of double column fractures (type J) according to Letournel-Judet classification. Based on fracture types, MWSP was used to fix fracture by modified Stoppa approach in 19 cases or combined with the ilioinguinal approach in 10 cases or combined with Kocher-Langenbeck approach in 9 cases. The operation time, blood loss, and complications were recorded. The effectiveness of reduction and the hip function were evaluated according to Matta score system and Merled' Aubigne and Postel score system. ResultsThe operation time was 85-210 minutes (mean, 130 minutes).The intra-operative blood loss was 450-900 mL (mean, 650 mL). There were 1 case of vascular avulsion, and 1 case of bladder injury during operation; there were 8 cases of venous thrombosis and 2 cases of fat liquefaction of incision after operation. Screw was implanted into the articular joint in 1 case on CT after operation. Matta X-ray assessment showed anatomical reduction in 9 cases, satisfactory reduction in 24 cases, and unsatisfactory reduction in 5 cases, and the satisfaction rate of reduction was 86.84%. Three patients had limb shorting of 0.8-1.0 cm when compared with normal limb. All patients were followed up for 7 to 18 months with an average of 10 months. Fractures healed well within 13-16 weeks with an average of 14 weeks. At 1 year after operation, the results were excellent in 9 cases, good in 21 cases, general in 5 cases, and poor in 3 cases, and the excellent and good rate was 78.95% according to the Merled'Aubigne and Postel hip score standards. ConclusionInvolving quadrilateral of acetabulum fracture can be fixed with MWSP by modified Stoppa approach or combined with other approaches to obtain good exposure, less invasion, satisfactory reduction, stable fixation, and low complications.

Objective To explore the effectiveness of unilateral percutaneous vertebroplasty (PVP) through mild side and severe side approaches in the treatment of elderly osteoporotic vertebral compression fracture (OVCF). Methods The clinical data of 100 patients with OVCF with symptoms on one side who were admitted between June 2020 and June 2021 and met the selection criteria were retrospectively analyzed. The patients were divided into the severe side approach group (group A) and the mild side approach group (group B) according to the cement puncture access during PVP, with 50 cases in each group. There was no significant difference between the two groups in terms of general information such as gender composition, age, body mass index, bone density, damaged segments, disease duration, and chronic comorbidities (P>0.05). The lateral margin height of the vertebral body on the operated side in group B was significantly higher than that of group A (P<0.001). The pain level and spinal motor function were evaluated using the pain visual analogue scale (VAS) score and Oswestry disability index (ODI) before operation, at 1 day, 1 month, 3 months, and 12 months after operation in both groups, respectively. Results No intraoperative or postoperative complications such as bone cement allergy, fever, incision infection, and transient hypotension occurred in both groups. Four cases of bone cement leakage occurred in group A (3 cases of intervertebral leakage and 1 case of paravertebral leakage), and 6 cases of bone cement leakage occurred in group B (4 cases of intervertebral leakage, 1 case of paravertebral leakage, and 1 case of spinal canal leakage), and none of them had neurological symptoms. Patients in both groups were followed up 12-16 months, with a mean of 13.3 months. All fractures healed and the healing time ranged from 2 to 4 months, with a mean of 2.9 months. The patients had no complication related to infection, adjacent vertebral fracture, or vascular embolism during follow-up. At 3 months postoperatively, the lateral margin height of the vertebral body on the operated side in groups A and B were improved when compared with preoperative ones, and the difference between pre- and post-operative lateral margin height of the vertebral body in group A was higher than that in group B, all showing significant differences (P<0.001). The VAS scores and ODI in both groups improved significantly at all postoperative time points when compared with those before operation, and further improved with time after operation (P<0.05). The differences in VAS scores and ODI between the two groups before operation were not significant (P>0.05); VAS scores and ODI in group A were significantly better than those in group B at 1 day, 1 month, and 3 months after operation (P<0.05), but no significant difference was found between the two groups at 12 months after operation (P>0.05). Conclusion Patients with OVCF have more severe compression on the more symptomatic side of the vertebral body, and patients with PVP have better pain relief and better functional recovery when cement is injected through the severe symptomatic side.
