Background: Scoliosis is a common deformity in patients with neuromuscular disorders which usually necessitates surgical correction. Patients with neuromuscular scoliosis are characterized by increased incidence of associated medical co-morbidities and higher postoperative complication rate; therefore, these patients are often managed with a wide multidisciplinary care team. Postoperative fever is a frequent complication after surgery which is often routinely investigated using different workup tests to rule out infection.

Background: Children with neuromuscular disorders have a significant chance of developing scoliosis and/or hip dislocation during childhood and adolescence and often undergo surgical reconstruction. Because of their high rate of medical comorbidities, these patients are at higher risk of postoperative complications and are therefore often comanaged, along with orthopaedics, by pediatric medicine and critical care teams. Fever during the postoperative stay is a frequent occurrence and often prompts extensive diagnostic workup which increases the cost and burden on the health system but have unclear effects on the care of the patient.

Simultaneous occurrence of tibial tubercle fracture and patellar tendon avulsion with double-hit injury of the knee extensor mechanism is an extremely rare condition. However, they become more frequent due to increased participation in sports and high-energy recreational activities at younger age. It represents a frequently missed diagnosis; therefore, high index of suspicion is required for the diagnosis of such injuries to avoid delays in the treatment which would lead to possible suboptimal functional outcome.

Study Design: Retrospective study.

Objective: The aim of this study was to evaluate the long-term clinical and radiological outcomes of the use of bone marrow mesenchymal stem cell concentrate obtained with selective cell retention technology using Cellect with a particular collagen scaffold, Healos for posterolateral spinal fusion.

Summary Of Background Data: With the increasing rate of spinal fusion, the problem of pseudarthrosis, which contributes to recurrent pain with patient disability, is considered to be the most common cause of revision lumbar spine surgery.

Study Design Prospective study. Objective The aim of this study was to evaluate the clinical and radiologic results of using free vascularized fibular graft (FVFG) for anterior reconstruction of the cervical spine following with varying levels of corpectomy. Methods Ten patients underwent anterior cervical reconstruction using an FVFG after cervical corpectomy augmented with internal instrumentation.

Introduction: Repair of peripheral nerve injuries is an intensive area of challenge and research in modern reconstructive microsurgery. Intensive research is being carried out to develop effective alternatives to the standard nerve autografting, avoiding its drawbacks. The aim of the study was to evaluate the effectiveness of a newly designed mechanical device for the reconstruction of the sciatic nerve in rats in comparison to nerve autografting and to assess the pain during the period of distraction neurogenesis.

There is great variability among microsurgeons as regards the use of prophylactic anticoagulant after revascularization and this is probably due to lack of comparative data. Also, there has been much debate regarding the benefit of anti-thrombotic therapies versus the risk of complications such as systemic bleeding and hematoma formation. To evaluate the effectiveness of postoperative low molecular weight heparin (LMWH) as a prophylactic anticoagulant therapy after microsurgical repair of the femoral artery and vein in rats.

Arthroscopic-assisted surgery of the trapeziometacarpal (TMC) joint has been described before for the treatment of TMC joint arthritis including, debridement, partial or total trapezectomy, and interpositional arthroplasty, but its use for fusion is not reported. TMC joint arthroscopy is a novel technique for arthrodesis which aims to maintain joint stability and strength. We have successfully used this technique to perform fusion of the TMC joint.
