Functional and radiographic assessments of post-traumatic asymmetrical ankle osteoarthritis treatment using supramalleolar osteotomies.

PURPOSE: This study's objective is to assess the effectiveness of supramalleolar osteotomies (SMOT) in the treatment of asymmetrical ankle osteoarthritis in terms of the improvement in alignment assessed radiographically and its impact on symptoms measured by the American Orthopedic Foot and Ankle Society ankle-hindfoot score (AOFAS ankle-hindfoot score). METHODS: Twelve patients participated in this prospective observational case series study. Standing anteroposterior, true lateral, and mortise views radiographs were taken. For preoperative planning, the lateral distal tibial angle (LDTA), talar tilt (TT), talocrural angle (TCA), and anterior distal tibial angle (ADTA) were all measured. A medial opening wedge osteotomy mainly was used to treat the varus arthritis ankle. A further oblique fibular osteotomy is frequently necessary. RESULTS: The male-to-female ratio was 3:1, and the mean age of the patients was 26.25 ± 13.032 years. There were highly statistically significant differences between pre-and post-operative AOFAS ankle-hindfoot score (p < 0.001). Statistically significant differences concerning ankle range of motion (p = 0.002, < 0.001) of dorsiflexion and planter flexion were detected. Comparison between pre-and post-operative patients' radiology characteristics shows statistically significant differences concerning TT (p = 0.016) and LDTA (p = 0.046). CONCLUSION: SMOT is very effective in the treatment of post-traumatic ankle osteoarthritis and postpones ankle fusion or total ankle replacements. This surgery significantly improves functional and radiological outcomes as well as the range of motion in the ankle. Meticulous preoperative planning by radiological measurements of different angles around the ankle is considered the crucial factor in success of that operation.

Ensuring safety and sustainability of radiotherapy services during the COVID-19 pandemic in resources constrain country: An Indonesian experience.

The global COVID-19 pandemic has placed a significant burden on the healthcare sector, overwhelming health services in affected countries worldwide. As healthcare facilities reorganize their services to adapt to this challenging problem, it is important that the sustainability of essential oncology services, including radiotherapy, is maintained. This article describes the Indonesian experience in ensuring sustainability of radiotherapy services during the pandemic, highlighting various important adjustments which were made to allow radiotherapy centers nationwide to continue operating while protecting staff and patients from the risk of disease transmission. As the backlog of patients waiting to start treatment will inevitably grow, some insight on how to proactively manage this issue will also be described.

Posterior-only surgical correction of adolescent idiopathic scoliosis: an Egyptian experience.

INTRODUCTION: The aim of this prospective case series study is to document safety and effectiveness of high density pedicle screws through posterior only approach with intraoperative wake-up test in correction of adolescent idiopathic scoliosis (AIS). METHODS: Between 2011 and 2015, all surgically treated patients for AIS were followed up for a minimum of 2 years. Clinical outcomes were evaluated using scoliosis research society-22 (SRS) questionnaire. All patients were classified according to Lenke classification. Major and minor curves Cobb angle as well as sagittal parameters were measured on whole spine X-rays. All patients underwent an intra-operative wake-up test after deformity correction and a minimum of 80% metal density of implants was used. RESULTS: This study included 50 patients. The mean age at time of surgery was 16.8 years. The mean follow-up period was 38.1 months. The mean correction rate for the coronal Cobb angle of the major curve was 79.12%, while that of the minor curve was 68.9%. The mean thoracic kyphosis angle was 38.4° preoperatively, 29.76° postoperatively and 30.36° at the last follow-up. The mean SRS-22 questionnaire scores improved significantly at the last follow-up (P > 0.001). There were no neurological deficits at the wake-up test. No cases of pseudarthrosis or metal failure were encountered. CONCLUSION: This is a prospective study of at least 80% metal density pedicle screws technique and intra-operative wake-up test in Egyptian patients with AIS. It proved to be an effective and safe technique in correction of radiological parameters, with no neurological or implant related complications. It allowed excellent scoliotic and kyphotic curves correction with minimal loss of correction. On the whole it led to better quality of life.

Surgical management of isthmic spondylolisthesis with radicular pain.

Forty-six patients with low-grade isthmic spondylolisthesis (27 grade I and 19 grade II) and radicular pain underwent surgery after failure of conservative treatment for 6 months. Fusion and decompression was carried out in 23 patients (group 1) and fusion without decompression in the other 23 patients (group 2). Instrumentation was used in 16 patients who had instability and hypermobility as seen by dynamic radiography. Results were assessed functionally and radiographically and graded according to Stauffer and Coventry. The follow-up was an average of 20 (12-36) months. In group 1 there were 17 patients with excellent to good results, and in group 2, 21 patients. There was no significant statistical difference between the fusion rate in the two groups. Decompression in addition to fusion in adults with low-grade isthmic spondylolisthesis and radicular pain does not appear to improve the functional outcome.
