STUDY DESIGN: A retrospective study. OBJECTIVE: The goal of this retrospective study was to describe the uncommon presentation of neurological deficits in patients with congenital kyphosis of the upper thoracic spine (T1-T4). SUMMARY OF BACKGROUND DATA: Congenital kyphosis is an uncommon deformity but can potentially lead to spinal cord compression and paraplegia, particularly in type I (failure of formation) deformities. Few reports have described compressive myelopathy associated with congenital kyphosis of the upper thoracic spine...

We report a case of anterior bronchogenic mediastinal cyst (ABMC) in old age patient underwent Robotic Thoracic Surgery (da Vinci Surgical System). Video-assisted thoracoscopic surgery (VATS) represents the routine approach in posterior bronchogenic mediastinal cyst, but some limitation for resection of mediastinal mass located in the anterior mediastinum has been reported. The introduction of da Vinci surgical system has overcome the surgical limits of VATS as two dimensional vision (2D) and the use of long rigid instruments with poor maneuverability in case of fine dissection...

Most cervico-mediastinal goiters are situated in the anterior mediastinal compartment, but according to the literature, 10-15 percent of them are located in the posterior mediastinum. Although most anterior mediastinal goiters can be removed by using the transcervical approach, cervico-mediastinal goiters in the posterior mediastinal may require additional extracervical incisions. We report the case of a huge cervico-mediastinal goiter extending from the neck retrotracheally to the posterior mediastinum. Surgical removal is the treatment of choice in such cases...

BACKGROUND: Prior studies have shown that the posterior cruciate ligament (PCL) may be partially resected during cruciate retaining (CR) total knee arthroplasty (TKA) using highly experienced hands and standard surgical technique; therefore, proper surgical technique is aimed at preservation and balance of the PCL during CR TKA. The central objective of this study is to evaluate the effectiveness of a simple surgical technique to prevent PCL damage during performance of a CR TKA. METHODS: Sixty embalmed cadaver specimens were randomized into 2 groups, experimental and control...

The patient was a boy of 7 years and 5 months of age, who underwent LDLT for acute liver failure at 10 months of age. HV stent placement was performed 8 months after LDLT because of intractable HV stenosis. At 7 years of age, his liver function deteriorated due to chronic rejection. The patient therefore underwent living donor liver retransplantation from his father. The HV was transected with the stent in situ. The IVC was resected due to stenosis. The pericardial cavity was opened and detached around the IVC to elongate the IVC...

BACKGROUND: Chordomas arise from remnants of the notocord and occur throughout the neuroaxis. En bloc resection of chordomas can prove especially challenging in the upper cervical spine secondary to the unique structural anatomy and intimate relationship to the vertebral arteries and spinal cord. CASE DESCRIPTION: We describe the resection of a C2-3 chordoma in a 55 year old female in two stage fashion with preservation of the vertebral arteries. First a posterior instrumented fusion and removal of the posterior elements was performed, followed by an anterior transmandibular en bloc resection with cage reconstruction with kick-plate support achievable with off-the-shelf products...

RATIONALE: The management of congenital scoliosis concentrates on early diagnosis and proper surgical treatment before the development of severe deformities. Decision making regarding the appropriate fusion levels, proper surgical treatment, and reduction amount of kyphoscoliosis is very important but difficult in the treatment of congenital scoliosis, especially in young children. PATIENT CONCERNS: We report an 11-year follow-up of revision surgery for fractional curve progression after combined anterior and posterior fusion without hemivertebra resection using pedicle screw fixation (PSF) in congenital kyphoscoliosis at age 4 years (a total 18-year follow-up)...

BACKGROUND: Acute myelopathy in the case of thoracic disc herniation (TDH) is an exceptional condition, for which the treatment is not codified. We present here the results of a standardized procedure on ten patients operated between December 2009 and December 2016 for acute myelopathy on TDH. METHOD: Our strategy consists of a cautious laminectomy without resection of the hernia on the day of admission. In the following days, a complementary thoracoscopic procedure is organized according to the neurological recovery and the nature of the hernia (calcified or fibrous)...

Gordon Preston, Toomas Anton
BACKGROUND: Plasma cell neoplasmas are a heterogenous group of neoplastic tumor lesions occurring secondary to disordered proliferation of cells from a monocyte lineage. Plasmacytoma is a rare lesion that accounts for 5% of all plasma cell neoplasms. The current recommended treatment for solitary plasmacytoma is moderate dose radiation therapy. For patients who are suffering from axial back pain, spinal instability, radiculopathy, or bowel/bladder dysfunction secondary to spinal cord compression, surgical intervention with spinal decompression and stabilization can be used as an adjuvant to radiation therapy...

Basal cell adenocarcinomas (BCACs) are rare malignant neoplasms of salivary glands, accounting for less than 1% of salivary gland tumors. Few cases of distant metastases have been reported. To our knowledge, metastases to the spine have not been previously reported in the literature. We presented an unusual case of a 50-year-old Thai male, who was diagnosed as basal cell adenocarcinoma of submandibular gland with pulmonary and cervical spine metastases with progressive myelopathy, treated with wide surgical resection of the soft tissue tumor and modified radical neck dissection, anterior cervical total corpectomy with fusion combined with posterior decompression and fusion of the cervical spine and surgical wound coverage by anterolateral thigh free tissue transfer, followed by adjuvant radiotherapy...

Talocalcaneal tarsal coalitions are a common source of foot pain, stiffness, and deformity. These coalitions are treated symptomatically with rest and periods of immobilization. When those measures fail, surgical resection is attempted. This procedure is an anatomic challenge with the consequence of leaving residual coalition. The residual coalition primarily results from difficulty with intraoperative imaging because fluoroscopy does not provide adequate detail of this area. Some investigators have recommended intraoperative computed tomography after resection with reasonable results...
