Anatomical variations of the subscapular pedicle and its terminal branches: an anatomical study and a reappraisal in the light of current surgical approaches.

Surg Radiol Anat 2018 Dec 13. Epub 2018 Dec 13.

Department of Plastic, Reconstructive and Aesthetic Surgery, Hôpital Européen Georges Pompidou, Assistance Publique des Hôpitaux de Paris, Université Paris Descartes, Paris V, 20 rue Leblanc, 75908, Paris Cedex 15, France.

Robot-assisted intravertebral augmentation corrects local kyphosis more effectively than a conventional fluoroscopy-guided technique.

Authors:

J Neurosurg Spine 2018 Nov 1:1-7. Epub 2018 Nov 1.

OBJECTIVEIntravertebral augmentation (IVA) is a reliable minimally invasive technique for treating Magerl type A vertebral body fractures. However, poor correction of kyphotic angulation, the risk of cement leakage, and significant exposure to radiation (for the surgeon, the operating room staff, and the patient) remain significant issues. The authors conducted a study to assess the value of robot-assisted IVA (RA-IVA) for thoracolumbar vertebral body fractures. Read More

Propeller flap reconstruction of irradiated sarcoma defects: A comparison.

J Plast Reconstr Aesthet Surg 2018 Nov 9. Epub 2018 Nov 9.

Department of Plastic and Reconstructive Surgery, St Vincent's Hospital, 41 Victoria Parade, Fitzroy VIC 3065, Australia.

Introduction: The treatment for soft tissue sarcomas has evolved to include radiotherapy, wide local excision and plastic surgical reconstruction. Goals for the reconstruction of these irradiated defects are the introduction of non-irradiated healthy tissue, tension-free closure and obliteration of potential dead space. Although many defects once required free tissue transfer for reconstruction, greater knowledge of anatomical vascular pattern has led to the increasing use of propeller perforator flaps, islanded and transposed into the defect.

Background: Selection of recipient vessels is one of the key factors for a successful microvascular reconstruction. Non-availability of primary recipient vessels in the vicinity necessitates surgeon to approach a remote second-line vascular access. Transverse cervical vessels (TCV) have been described as second-line vascular access for head-and-neck reconstructions. Read More
