Middle cingulate cortex function contributes to response to non-steroidal anti-inflammatory drug in cervical spondylosis patients: a preliminary resting-state fMRI study.

BACKGROUND AND OBJECTIVE: Cervical spondylosis (CS) is often accompanied by persistent cervical pain, and psychological complications including depression and anxiety, which aggravate pain. Past studies have revealed brain alterations in chronic pain patients. However, the cortical mechanism for NSAID (non-steroidal anti-inflammatory drug) responders relative to non-responders is still lacking. Therefore, we aimed to investigate the brain functional differences between responders to NSAID relative to non-responders using amplitude of low-frequency fluctuation (ALFF) and dynamic functional connectivity variance (DFCV). To our knowledge, our study is the first to investigate the DFCV in CS patients. MATERIALS AND METHODS: We first explored the differences in psychological inventories in CS patients who respond to NSAID vs non-responders. The voxel-wise ALFF was calculated and compared between CS patients and healthy controls. The ALFF within the resultant clusters were extracted and compared between responders and non-responders. DFCV among the resulting clusters was compared in responders vs non-responders. RESULTS: We found that (1) compared to responders, non-responders exhibited higher levels of anxiety and depression; (2) relative to healthy controls, CS patients exhibited altered ALFF within the middle cingulate cortice (MCC), cerebellum, and middle frontal gyrus (MFG); (3) moreover, compared with responders, non-responders exhibited lower ALFF within MCC; furthermore, non-responders also exhibited increased DFCV between MCC and cerebellum, and between MCC and MFG. CONCLUSION: Our data indicate that psychological comorbidities (e.g., anxiety) influence response to NSAID in CS patients. Relative to NSAID responders, non-responders had altered MCC function, which may be associated with anxiety in CS patients.

Management of Complex Open Tibial Plateau Fracture: A Case Report on the Application of Locked Plate External Fixation Technique during Bone Callus Formation stage to Replace transarticular External Fixation.

Transarticular external fixation is primarily used for open fractures involving the joint. However, its biggest drawback is the potential forjoint dysfunction. The article reports a successful case with complex open tibial plateau fracture treated using locked plate external fixation technique during bone callus formation stage to replace transarticular external fixation. We present a case of a 55-year-old male who sustained a complex open fracture of the tibial plateau. In addition, he also suffered from multiple rib fractures, a fibula fracture, a clavicle fracture, hemorrhagic shock, and lung contusion. The patient has occurred tibial bone infection after undergoing open reduction and transarticular external fixation for fracture management. Our team skillfully applied locked plate external fixation technique during bone callus formation stage to replace transarticular external fixation. Ultimately, the approach not only successfully controls infection and achieves fracture healing but also preserves knee joint function after five years of follow-up. In conclusion,the application of locked plate external fixation technique during bone callus formation stage to replace transarticular external fixation is a valuable approach that orthopedic clinicians should consider and learn from when managing complex intra-articular fractures.

Limb Fractures Treated With the Novel Plate Osteosynthesis Application Technique: Second to Minimally Invasive Plates osteosynthesis.

BACKGROUND: The main aim of this article was to propose a new concept of minimally invasive surgery for treating limb fractures, named as second to minimally invasive plates osteosynthesis (STMIPO). METHODS: We have described the STMIPO technique in a step-wise and standardized manner based on our findings from a study involving six patients treated at our institution. All patients with fracture achieved satisfactory outcomes. RESULTS: Ours clinical trials have shown that the STMIPO technique can be successfully applied in various limb fractures, including fibula fractures, tibial fractures, femur fractures, humerus fractures, ulna fractures, and radius fractures. All fracture patients achieved satisfactory outcomes. CONCLUSION: As a new minimally invasive technology, the STMIPO technique can serve as an alternative solution for fractures that are difficult to reduce with minimally invasive plates osteosynthesis (MIPO).

Treatment of bilateral Posterior Tibial Compartment Syndrome using a Novel Surgical Approach: A Case Report of the Posterior Approach.

Osteofascial compartment syndrome is a serious surgical emergency that requires prompt diagnosis and treatment. It presents a challenge for surgeons due to its high disability rate and difficult management. Early fasciotomy decompression is crucial in preventing severe complications. Classic fasciotomy approaches for tibial osteofascial compartment syndrome include double-incision and single-incision techniques.This paper presents a case of a 24-year-old female with bilateral tibial posterior compartment syndrome resulting from prolonged squatting after alcohol intoxication, which is a relatively rare mechanism. We employed an innovative posterior approach to manage the patient with tibial posterior compartment syndrome. Ultimately, we successfully preserved the patient's legs and achieved a good functional recovery.The paper reported a rare case with bilateral posterior tibial compartment syndrome resulting from squatting for 10 hours after alcohol intoxication. The patient achieved favorable outcomes in lower limb function following treatment with a new fasciotomy approach, the posterior approach.The new approach for treating posterior tibial compartment syndrome can serve as a valuable reference for surgeons.

Application of Oblique Lateral Interbody Fusion in Treatment of Lumbar Spinal Tuberculosis in Adults.

OBJECTIVE: The purpose of the present paper was to evaluate the safety and clinical efficacy of mini-open retroperitoneal oblique lumbar interbody fusion (OLIF) for the treatment of lumbar spinal tuberculosis. METHODS: A total of 115 patients who suffered from lumbar spinal tuberculosis from June 2014 to December 2017 were included in this research. A total of 59 patients underwent OLIF and percutaneous pedicle screw fixation (OLIF group) and 56 patients underwent the anterior-only approach (anterior-only group). All patients were followed up for at least 24 months. Operation time, blood loss, and rate of complications were used to assess the safety of these two techniques. The visual analog scale (VAS) and the Oswestry disability index (ODI) were used to evaluate the relief of neurological and functional symptoms. The erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were measured to investigate the activity and recurrence of spinal tuberculosis. The Cobb angle, the sagittal vertical axis of the spine (SVA), the pelvic tilt (PT), the sacral slope (SS), the pelvic incidence (PI), and postoperative Frankel classification were also used to assess the efficiency of the spine deformity correction and the recovery of long-term neurological function. RESULTS: Most patients were successfully treated with OLIF and the anterior-only technique and attained satisfactory clinical efficiency during the 24-month follow-up period. In the perioperative period, the mean operative time (154.68 ± 23.64 min, P < 0.001), the mean blood loss (110.57 ± 87.67 mL, P < 0.001), and the mean hospital stay (9.55 ± 3.62 days, P < 0.001) of the OLIF group were all significantly lower than in the anterior-only group (172.49 ± 25.67 min, 458.56 ± 114.89 mL, and 14.89 ± 3.89 days, respectively). A total of 10 patients (16.95%) experienced complications in the OLIF group, including neurological injury, segmental artery and iliac vein lacerations, peritoneal injury, instrument failure, and infection of incisions; this rate of complications was lower than in the anterior-only group (37.50%, P = 0.013). Regard to spinal deformity correction, the Cobb angle (9.42° ± 1.72°, P = 0.032), the SVA (2.23 ± 1.07 cm, P = 0.041), the PT (14.26° ± 2.37°, P = 0.037), and the SS (39.49° ± 2.17°, P = 0.042) of the OLIF group at last follow-up were all significantly different when compared to the anterior-only group (14.75° ± 2.13°, 3.48 ± 0.76 cm, 18.58° ± 1.45°, and 36.78° ± 1.96°, respectively). The VAS and the ODI of the OLIF group at 1 week postoperatively (3.15 ± 0.48, 21.85 ± 3.78, P = 0.032, 0.037) and at the last follow-up (2.12 ± 0.35, 16.70 ± 5.25, P = 0.043, 0.035) were both lower than for the anterior-only group (5.18 ± 0.56, 29.83 ± 5.42 and 3.67 ± 0.62, 20.68 ± 6.23). The Frankel classification was improved for both OLIF and anterior-only patients; however, there were 35 cases (59.32%) classified as Frankel grade E in the OLIF group and 22 cases (39.29%, P = 0.021) in the anterior-only group CONCLUSION: The OLIF surgical technique for single lumbar (L2 -L5 ) spinal tuberculosis is less invasive, has lower complication rates, and is more efficient than the anterior-only approach. However, the long-term effects of this surgical technique still need to be explored.
