Does minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) influence functional outcomes and spinopelvic parameters in isthmic spondylolisthesis?

PURPOSE: We assessed the efficacy of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in patients with low-grade isthmic spondylolisthesis. METHODS: We included 24 symptomatic patients who underwent MIS-TLIF between December 2017 and December 2020. Patients were followed up clinically by the Oswestry Disability Index (ODI) and Visual Analogue Scale (VAS) for back and VAS for leg pain, as well as radiological radiographs after 6 weeks, 6 months, and at final follow-up (at least 12 months). Measured parameters included C7 sagittal vertical axis (SVA), pelvic tilt (PT), pelvic incidence (PI), sacral slope (SS), Meyerding slip grades, lumbar lordosis (LL), L1-L4 angle, L4-S1 angle, and segmental lordosis (SL) of the affected segment. The mismatch between the PI and LL was also measured. RESULTS: VAS for back, VAS for leg pain, and ODI significantly improved postoperatively (all p < 0.001). We observed significantly decreased mean values of PT and slip percentage and increased mean values of SS and LL (all p < 0.05). We observed a significant reduction in L1-L4 lordosis and a significant increase in L4-S1 lordosis. The final PT, SS, and LL (total and L1-L4) were significantly higher in group III patients (n = 15) than the values of group II patients (n = 9). None of the patients became unbalanced postoperative, and all patients had a normal matching between the PI and the LL postoperatively. CONCLUSIONS: MIS-TLIF is a safe procedure for managing low-grade isthmic spondylolisthesis with significant improvement in clinical and radiological outcomes. It can correct and maintain a proper spinopelvic alignment.

A modification of the Ponseti method for clubfoot management: a prospective comparative study.

PURPOSE: We aimed to compare our parent-based exercise programem's efficacy with the foot abduction brace (FAB) Ponseti manipulation as a retention programme. METHODS: We conducted this prospective multicentre cohort study between August 2009 and November 2019. The included children were allocated into one of two groups according to the retention protocol. The Pirani and Laaveg-Ponseti scores were used to assess the feet clinically and functionally. Radiological assessment was performed using standing anteroposterior and lateral radiographs of the feet. We assessed the parents' satisfaction and adherence to the retention method. SPSS version 25 was used for the statistical analysis. RESULTS: A total of 1265 feet in 973 children were included. Group A included 637 feet managed with FAB, while group B included 628 feet managed with our retention programme. All patients were followed up to the age of four years. At the final follow-up, Pirani scores in group A participants were excellent, good and poor in 515, 90, and 32 feet, respectivel, while in group B the scores were excellent, good and poor in 471, 110 and 44 feet, respectively. The mean total score of Laaveg-Ponseti was 87.81 (sd 19.82) in group A and 90.55 (sd 20.71) in group B (p = 0.02). Group B participants showed higher satisfaction with the treatment method (p = 0.011) and more adherence to the treatment (p = 0.013). CONCLUSION: The deformity's recurrence related to the brace's non-compliance in the Ponseti method might be reduced by substituting the brace with our home-based daily stretching exercises. LEVEL OF EVIDENCE: II.

Is the Denis Browne Splint a Myth? A Long-Term Prospective Cohort Study in Clubfoot Management using Denis Browne Splint Versus Daily Exercise Protocol.

The Ponseti technique is successful in idiopathic clubfoot management. However, the leading cause of relapse and recurrence is nonadherence to the Denis Brown bracing protocol. This necessitates more extensive soft tissue surgeries. Based on a detailed up-to-date search, we have found that no other studies provide such a modified Ponseti technique. This study is unique, as it depends on using specific stretching exercises instead of bracing during management. Between August 2009 and June 2019, a consecutive series of 194 isolated idiopathic clubfoot patients (251 feet) were included in this study. The mean follow-up was 93 months (range 72 to 146), mean 91.8 months. All patients underwent a clinical and functional assessment using the Laaveg-Ponseti score and radiological assessments. There were 132 boys (68.1%) and 62 girls (31.9%), a male-to-female ratio of 2:1. The mean age at initiation of treatment was 14.9 days. According to the Laaveg-Ponseti score, 51.7% yielded excellent results, 35.3% yielded good results, 11.55% yielded fair results, and 1.59% yielded poor results. Bracing noncompliance has been identified as a major cause for treatment failure. This presented exercise protocol not only eliminates the need for bracing and reduces the cost for the affected individuals but also provides excellent clinical and radiographic end results, comparable to the original treatment protocol using the Denis Brown brace.

Vascular injury in tubular lumbar microdiscectomy, case report and literature review.

Vascular injury in lumbar disk disease is a common complication reviewed in the literature. In our study, we reviewed the rare complication of vascular injury that occurs during lumbar microscopic tubular discectomy. The patient is a 46-year-old male, diabetic, hypertensive and a smoker who presented with a history of backache and right-sided radiculopathy to S1 dermatome for 6 weeks. Conservative measures failed, and we planned and performed microscopic tubular discectomy at the level of L5-S1. Immediately postoperatively, the patient developed acute, sharp, burning pain in the left leg, partially relieved on hip flexion, with diminished distal pulsation of dorsalis pedis, popliteal and femoral. Urgent consultation with a vascular surgeon included a computed tomography angiography which confirmed a vascular injury of the left iliac artery and vein near the bifurcation. The plan involved urgent retroperitoneal exploration of the left iliac vessels, and primary repair with synthetic graft was done with distal embolectomy to regain distal pulsation postoperatively. Further follow-up revealed that the repair was successful.
