Talus Fractures: An Update on Current Concepts in Surgical Management.

Talus fractures can be challenging injuries to treat because of complex talar shape, an abundance of articular cartilage, a potentially unforgiving soft-tissue envelope, and an easily injured blood supply. In addition, the spectra of energy involved, soft-tissue injury, and the fracture pattern are wide. Temporizing treatment is sometimes required, including débridement of open fractures, reduction of dislocations, and occasionally spanning external fixation. Definitive treatment first requires an understanding of the fracture pattern, including location and fracture line orientation. Multiple options for surgical exposure exist and are selected based on the fracture pattern and condition of the soft tissues. Newer fixation techniques, including the use of fixed-angle and minifragment implants, are useful in achieving stable fixation.

Update on imaging of the discoid meniscus.

Discoid menisci represent a range of morphological meniscal variants, most commonly involving the lateral meniscus. Clinical presentation ranges from an asymptomatic incidental finding to snapping, pain, swelling and reduced range of knee movement. Symptomatic presentation of discoid menisci is usually due to meniscal tears and instability resulting from abnormal meniscal morphology and ultrastructure, with absent peri-meniscal ligamentous and meniscocapsular attachments characteristic of the Wrisberg sub-type. This article reviews the current classification systems of discoid menisci, gross morphological characteristics of each sub-type and ultrastructure. Clinical presentation, arthroscopic findings and indirect radiological diagnostic criteria are described, as are the MRI findings of normal and pathological discoid menisci. Current concepts of surgical management and outcomes of the discoid meniscus are also briefly discussed.

Fractures of the proximal ulna: current concepts in surgical management.

Fractures of the proximal ulna range from simple olecranon fractures to complex Monteggia fractures or Monteggia-like lesions involving damage to stabilizing key structures of the elbow (i.e. coronoid process, radial head, collateral ligament complex).In complex fracture patterns a computerized tomography scan is essential to properly assess the injury severity.Exact preoperative planning for the surgical approach is vital to adequately address all fracture parts (base coronoid fragments first).The management of olecranon fractures primarily comprises tension-band wiring in simple fractures as a valid treatment option, but modern plate techniques, especially in comminuted or osteoporotic fracture types, can reduce implant failure and potential implant-related soft tissue irritation.For Monteggia injuries, the accurate anatomical restoration of ulnar alignment and dimensions is crucial to adjust the radiocapitellar joint.Caution is advised if the anteromedial facet (anatomical insertion of the medial collateral ligament) of the coronoid process is affected, to avoid posteromedial instability.Radial head reconstruction or replacement is essential in Monteggia-like lesions to restore normal elbow function.The postoperative rehabilitation programme should involve active elbow motion exercises without limitations as early as possible following surgery to avoid joint stiffness.Cite this article: EFORT Open Rev 2019;4:1-9.

Review of Past Reports and Current Concepts of Surgical Management for Craniosynostosis.

The purposes of surgery for craniosynostosis are to release increased intracranial pressure and to normalize cranial shape. The procedure was developed from a simple strip craniectomy in practice which ranged from the removal of the fused suture before the 1960s to total calvarial remodeling after 1970s and later methods of the 1990s, such as distraction and its modifications. According to its history, craniofacial surgeons might be changing their procedures with more effective, than less invasive ways. Since the late 1990s, when the distraction was applied to the craniofacial surgery, the gradual expansion, in particular of the anterior cranium, common in Japan, has long been controversial until the Caucasians accepted its use for the posterior cranium. Currently, the method may revert to the old procedure because a more sophisticated and better morphological result can be obtained depending on the types of deformity, even if a little more invasive maneuver is required. In other words, if treatment can be performed in optimal time, the procedures that were developed in the last half a century should be altered to each condition.

Prognostic Benefit of Surgical Management of Renal Cell Carcinoma Invading the Inferior Vena Cava.

Renal cell carcinoma (RCC) accounts for approximately 3% of adult malignancies and 90-95% of neoplasms arising from the kidney. One of the unique features of RCC is the tumor thrombus formation that migrates into the venous system including renal vein (RV) and inferior vena cava (IVC). Only 10% of patients with RCC present with the classic triad of flank pain, hematuria and defined mass, while 25-30% of affected patients are asymptomatic. Signs of para-neoplastic syndrome such as hypercalcemia, hypertension, anemia, cachexia and increased erythrocyte sedimentation rate (ESR) are often apparent. Extension of tumor thrombus into the venous system is depicted by radiological examinations, such as contrast enhanced Computed Tomography (CT), Magnetic Resonance Imaging (MRI) and vena cavography. The level of the thrombus is mostly determined according to the Mayo classification. Despite recent research on the therapeutic strategies against advanced RCC, surgical resection appears the only potentially curative approach. Aggressive surgical management including nephrectomy with thrombectomy is currently the standard therapeutic approach for RCC patients with tumor thrombus extending to the RV or the IVC. Pre-surgical down-staging with the use of molecular targeted therapy has also been proposed. Alternative therapies, such as radio- and chemotherapy proved insufficient. The aim of this review is to evaluate the results of surgical treatment for RCC invading IVC with special reference to the extent of its histological spread. Review of recent world literature was accomplished to provide an update on the current concepts of surgical management of the disease.

Mesenteric ischemia: Pathogenesis and challenging diagnostic and therapeutic modalities.

Mesenteric ischemia (MI) is an uncommon medical condition with high mortality rates. ΜΙ includes inadequate blood supply, inflammatory injury and eventually necrosis of the bowel wall. The disease can be divided into acute and chronic MI (CMI), with the first being subdivided into four categories. Therefore, acute MI (AMI) can occur as a result of arterial embolism, arterial thrombosis, mesenteric venous thrombosis and non-occlusive causes. Bowel damage is in proportion to the mesenteric blood flow decrease and may vary from minimum lesions, due to reversible ischemia, to transmural injury, with subsequent necrosis and perforation. CMI is associated to diffuse atherosclerotic disease in more than 95% of cases, with all major mesenteric arteries presenting stenosis or occlusion. Because of a lack of specific signs or due to its sometime quiet presentation, this condition is frequently diagnosed only at an advanced stage. Computed tomography (CT) imaging and CT angiography contribute to differential diagnosis and management of AMI. Angiography is also the criterion standard for CMI, with mesenteric duplex ultrasonography and magnetic resonance angiography also being of great importance. Therapeutic approach of MI includes both medical and surgical treatment. Surgical procedures include restoration of the blood flow with arteriotomy, endarterectomy or anterograde bypass, while resection of necrotic bowel is always implemented. The aim of this review was to evaluate the results of surgical treatment for MI and to present the recent literature in order to provide an update on the current concepts of surgical management of the disease. Mesh words selected include MI, diagnostic approach and therapeutic management.

Current concepts in surgical management of pediatric lung and chest wall diseases

The management of pediatric lung and chest wall diseases has changed dramatically in the last decade because of the application of minimally invasive surgical techniques. This review will try to highlight some of the more significant recent contributions. Most of the papers quoted will show that the application of minimally invasive surgery to the treatment of common problems such as empyema, pneumothorax, and lung biopsy has significantly altered our treatment algorithms, because of decreased morbidity and improved outcomes compared to standard surgical or medical treatment plans. This has also been true for pediatric chest wall deformities, which previously were treated in only the most severe cases and thought to be mostly cosmetic in nature. More recent reports now show statistically significant improvements in cardio-pulmonary physiology as well as quality of life. The application of less invasive surgical procedures for lung and chest wall diseases has warranted earlier intervention, with better outcomes, and less morbidity than previously used techniques. A clear understanding of these techniques and their benefits is important for the referring and treating physician as previously used treatment protocols may no longer provide the best patient care.

Current Concepts of Surgical Management of Deformities of the Lower Extremities in Cerebral Palsy

In cerebral palsy, principles involved in proper selection of orthopedic management of the lower limbs include diagnosis, timing, goals, degree of involvement, linkage, kinetic electromyography, retention of neonatal automatisms, and dynamic versus fixed deformity, as well as the physical plant and professional skills. Specific lower extremity problems in the hip, knee, ankle, and foot must be analyzed and management for each should be approached on a rational basis. Unsolved enigmatic problems of etiology, pathways of neonatal automatisms that impose abnormal posturing, neurophysiologic mechanisms of spasticity, athetosis, rigidity and ataxia, pathogenesis of contracture, linkage biomechanics, and the neurologic, including the biomechanical effects of surgical intervention, require special research programs.

Sweat gland carcinoma: current concepts of surgical management

• In three new cases of sweat gland carcinoma that we observed within recent years, the sites were the axilla, back, and arm. Axillary lymph node dissections were performed in two of the patients and the nodes were normal. Preoperative diagnoses were hydroadenitis, squamous cell carcinoma of the skin, and pyogenic granuloma. In one patient who was followed up for four years, there has been no recurrence; the follow-up period for the other two has been short. Sweat gland carcinoma is an uncommon neoplasm that occurs mostly in the older age groups. It may be very slow growing and is extremely difficult to diagnose preoperatively. Lymph node metastases are frequent and overall survival is poor. Prognosis is related to histologic cell type and presence or absence of lymph node metastases. Treatment by wide local excision of the lesion and primary regional node dissection is recommended. ( Arch Surg 111:884-885, 1976)
