The functional or vital prognosis may be affected by the rare vascular accidents resulting from orthopedic operations. During a 10 year period (1970-1980), 55 vascular lesions were observed in 40 patients, and were either arterial (40 cases) or venous (15 cases) in type. Vascular injuries in 9 cases were due to spinal operations (cervical, lumbosacral or herniated disc arthrodesis), in 7 cases to shoulder operations (recurrent dislocation, excision of first rib), in 9 cases to hip surgery (prosthesis, plate and screws, fractured acetabulum), and in 15 cases to operations on the lower limbs (osteosynthesis of femur or tibia, meniscus operations, etc.). Emergency operation was necessary in 18 cases because of a hemorrhagic or ischemic syndrome, all other cases except three requiring secondary surgery for false aneurysms, arteriovenous fistulae, or residual ischemia. Four patients (10%) died, three following hip surgery, and 8 developed complications. The frequency, mechanism, diagnostic and therapy of these lesions are discussed.

Free Functional Muscle Transfer in Brachial Plexus Injury Patients With Subclavian Artery Injury Using Arteriovenous Loop Grafts.
Microsurgery

Department of Orthopaedic Surgery, Faculty of Medicine Siriraj Hospital, Mahidol University, Bangkok, Thailand.
Background: Free functional muscle transfer (FFMT) for brachial plexus injury (BPI) requires adequate donor arterial flow for successful anastomosis. However, concomitant BPI and subclavian artery injury are not uncommon. Arteriovenous (AV) loop graft is one of the methods used to extend vessels to areas with vascular depletion.

Traumatic optic neuropathy (TON) has been regarded a vision-threatening condition caused by either ocular or blunt/penetrating head trauma, which is characterized by direct or indirect TON. Injury happens during sports, vehicle accidents and mainly in military war and combat exposure. Earlier, we have demonstrated that remote ischemic post-conditioning (RIC) therapy is protective in TON, and here we report that AMPKα1 activation is crucial.

Posterior sternoclavicular joint (SCJ) dislocation is a rare but potentially life-threatening injury due to its proximity to critical mediastinal structures. Early diagnosis and prompt management are essential to prevent severe complications such as vascular or respiratory compromise. We report a case of a 23-year-old male who presented to our emergency department five days after a high-energy motor vehicle accident with isolated, closed posterior dislocation of the SCJ.

Article Synopsis
- Humans have a special ability to use tools thanks to the dexterity of their hands, but many lose this ability due to injuries or strokes, prompting further research on human hand function.
- Previous studies primarily focused on coordinated movements for reaching and grasping, but there is a gap in understanding how we manipulate complex objects.
- This study tested two hypotheses about hand synergies in manipulation compared to reaching and grasping, revealing that manipulation requires more synergies and that the specific synergies differ between the two actions, highlighting the need for more focused research to improve prosthetics and rehabilitation.
surgery for rectal cancer often presents multiple tactical and technical challenges due to factors such as the tumor's extent, limited anatomical space, proximity to the anal sphincter complex, and the use of neoadjuvant radiotherapy. These factors can significantly increase the complexity of surgery and the risk of both immediate and delayed complications, which can occur intraoperatively or postoperatively. Objective: the aim of this study was to retrospectively analyze the causes, diagnostic methods, and management of complications in patients who underwent surgery for rectal cancer.
