Post-laminectomy spinal deformity occurs in 50% of children undergoing laminectomies for cord tumors. Kyphosis is the most frequent deformity found. The integrity of the facet joints appears to be one of the most important factors in the development of this kyphosis. More children are surviving after treatment of these tumors and a pessimistic attitude is not warranted. Observation of a progressing deformity is not acceptable treatment. When kyphosis develops, early prompt bracing must be started. For a progressive or severe kyphosis, an anterior spine fusion is indicated. This is reinforced by a posterior fusion with Harrington instrumentation. Surgical reconstruction is indicated in children recovering from extensive laminectomies but with a good prognosis.

Pediatric spinal arachnoid cysts with compressive myelopathy: single-center experience and update on surgical management.
Childs Nerv Syst

Article Synopsis
- This study evaluates the surgical outcomes for pediatric patients with primary spinal arachnoid cysts (SACs) that cause compressive myelopathy, updating classification and management approaches.
- The analysis included 17 children, revealing that cysts typically extended over 5.2 vertebral levels and were often intradural, with surgical procedures divided between laminectomy and laminoplasty; post-operative spinal deformities were infrequent, especially in the laminoplasty group.
- The findings suggest that marsupialization or microsurgical excision are effective for managing symptomatic SACs, and laminoplasty is recommended to minimize the risk of spinal deformities in growing children.

Spinal epidural hematoma (SEH) is a rare but serious condition characterized by the accumulation of blood in the spinal epidural space. As SEH progresses, it can result in permanent damage or paralysis if not treated promptly. We report three cases of SEH: one spontaneous and two traumatic.

The posterior ligamentous complex plays a pivotal role in spinal stability during complex movements, especially at the cervical vertebral level. Its disruption leads to the development of post-laminectomy kyphosis. The present case emphasizes the challenges in managing post-laminectomy kyphosis, restoring spinal alignment, and the importance of the posterior tension band as a spine stabilizer.

Background: Cervical posterior instrumentation and fusion is often performed to avoid post-laminectomy kyphosis. However, larger comparative analyses of cervical laminectomy with or without fusion are sparse.
Methods: A retrospective, two-center, comparative cohort study included patients after stand-alone dorsal laminectomy with (n = 91) or without (n = 46) additional fusion for degenerative cervical myelopathy with a median follow-up of 59 (interquartile range (IQR) 52) months.

Department of Neurosurgery, Neurosciences Centre, All India Institute of Medical Sciences, New Delhi, 110029, India.
Background: Pediatric cervical kyphosis is a distinct entity with diverse etiology (congenital, syndromic, traumatic, metabolic or neoplastic). Surgical correction in pediatric population is challenging due to their growing spine and low blood volume.
Purpose: To analyse their presentation, surgical techniques and outcome of pediatric cervical kyphosis and systematically review the pertinent literature.
