OBJECTIVE: To assess the risk of glove perforation during common maneuvers or events in trauma-related orthopedic surgical procedures. METHODS: Four investigators executed six high-risk maneuvers in a simulated laboratory setting. Alternative techniques were also performed for most maneuvers. Glove integrity was examined by two standard methods of fluid leak testing. The rates of perforation were compared between techniques using Chi-squared and Fisher's exact tests...

We present a novel three Revolute-Revolute-Spherical (3RRS) wearable fingertip device for the rendering of stiffness information. It is composed of a static upper body and a mobile end-effector. The upper body is located on the nail side of the finger, supporting three small servo motors, and the mobile end-effector is in contact with the finger pulp. The two parts are connected by three articulated legs, actuated by the motors. The end-effector can move toward the user's fingertip and rotate it to simulate contacts with arbitrarily-oriented surfaces...

BACKGROUND: Although the method has been used widely, one of the greatest challenges for intramedullary nailing is to position the distal locking screw. A new technology, the electromagnetic navigation system, is a radiation-free way to locate the position of the drill bit and provide 3-dimensional real-time feedback of location and orientation of the drill bit relative to the locking holes. The purpose of our study was to evaluate the reliability and efficiency of the free-hand technique compared to the new electromagnetic navigation system...

"Aabis" is a school-aged boy from a predominantly conservative Muslim nation who presented to a tertiary developmental-behavioral pediatric (DBP) clinic to seek "expert opinion" for significant social and learning difficulties in the context of a history of frequent falling and "clumsiness." He was seen by a psychiatrist in his home country, who ordered an electroencephalogram and "brain map" (both normal), and received occupational and physical therapies. Frequent tantrums and intense emotional reactions to minor events-revealed to be related to a history of repeated physical beatings from groups of his "friends"-prompted referral to the DBP clinic...

Pertrochanteric fractures in elderly patients represent a major health issue. The available surgical options are fixation with extramedullary devices, intramedullary nailing, and arthroplasty. Intramedullary nailing for hip fractures has become more popular in recent years. Advantages of intramedullary nailing for hip fracture fixation include a more efficient load transfer due to the proximity of the implant to the medial calcar, less implant strain and shorter lever arm because of its closer positioning to the mechanical axis of the femur, significantly less soft tissue disruption and periosteal stripping of the femoral cortex, shorter operative time and hospital stay, fewer blood transfusions, better postoperative walking ability, and lower rates of leg-length discrepancy...

PURPOSE: To introduce the concept of fracture reduction with positive medial cortical support and its clinical and radiological correlation in geriatric unstable pertrochanteric fractures. METHODS: A retrospective analysis of 127 patients (32 men and 95 women, with mean age 78.7 years) with AO/OTA 31A2.2 and 2.3 hip fractures treated with cephalomedullary nail (PFNA-II or Gamma-3) between July 2010 and June 2013 was performed. They were classified into three groups according the grade of medial cortical support in postoperative fracture reduction (positive, neutral, and negative)...

OBJECTIVES: To compare the free-hand (FH) technique of placing interlocking screws to a commercially available electromagnetic (EM) targeting system in terms of operating time, radiation dose, and accuracy of screw placement. METHODS: Between September 2011 and July 2012, we prospectively randomized 100 consecutive femur shaft fractures in 99 patients requiring intramedullary nails to either FH using fluoroscopy (n = 43) or EM targeting (n = 38; Sureshot). SETTING: Single Level 1 University Hospital Trauma Center...

BACKGROUND: In 1969, Kolipp and Hoffmann isolated Trichophyton (T.) thuringiense spec. nov. Koch when they performed their thesis dealing with the distribution and epidemiology of dermatophytes and keratinophilic fungi in mice and other small mammals. At that time, T. thuringiense was detected as saprophytic fungus of the skin of different mice species (e.g. Mus musculus) both in rural and urban settings in the area of Thuringia in Germany. There were no further reports on this dermatophyte species until now, neither in animals, nor in man...

BACKGROUND: Distal interlocking screw insertion in intramedullary nailing of long-bone fracture is a challenging task for orthopedic surgeons. It is difficult particularly when the surgeon is in his learning stage or when image intensifier is not available. We describe a radiation-free technique of distal interlocking screw insertion which is easy and practicable. MATERIALS AND METHODS: In this technique, a same length nail is placed over the skin (outer nail) and through its distal-most screw hole, a 3...

OBJECTIVE: Greater stability in intramedullary osteosynthesis using angle-stable fixation with intramedullary nails and proximal locking screws. A novel screw-and-sleeve system (ASLS®, Synthes GmbH, Oberdorf, Switzerland) is applied using normal cannulated nails. Decisions can be made intraoperatively. INDICATIONS: This technology widens the range of indications for intramedullary nailing: The smaller and less stable the fragment requiring fixation, the greater the indication for angular stable fixation of the proximal and/or distal fragment...

BACKGROUND: During the last decades, intramedullary nailing has become the standard treatment for diaphyseal fractures of long bones. Numerous innovative techniques and devices have been proposed to simplify distal locking. Each has its own limitations and, as a result, the fluoroscopy-dependent "free-hand technique" remains the most popular method. However, radiation exposure to the patient and operating room staff remains a concern. METHODS: Before the development of a new radiation-independent, nail-mounted targeting system, we mathematically analyzed the aiming accuracy that such a system has to achieve...

Removing a broken guide wire is difficult and challenging. This article reports a method that was used to successfully remove a broken guide wire in 3 patients who underwent operative treatment for intertrochanteric fractures of the femur. Under general anesthesia, the first patient was placed on the orthopedic fracture table, and closed reduction of the hip fracture was performed under the image intensifier. A 2-mm non-threaded pin was used in the center of the femoral neck, and the amount of reaming required was determined...

Blood pressure saggy? Cardiac output low? Oliguria? Increasing acidosis? Peripheries a bit cool? Poor cardiac history? No problem. Just start some dobutamine and watch the numbers improve. And if the patient happens to die, that is their fault. Or is it? Catecholamines are long-established drugs that have never undergone formal testing of long-term outcomes and safety. Their use requires re-evaluation in the light of a wide range of deleterious actions and retrospective studies suggesting harm.

Successful penetration of bone is dependent on several factors, including bone quality, drill bit and pin design, and drilling technique. Wires are also used in bone drilling, and the tip configuration can affect the efficiency of bone penetration. Incorrect use of drill bits, pins, and wires may result in complications such as thermal necrosis and hardware breakage.

BACKGROUND: Extracting broken segments of intramedullay nails from long bones can be an operative challenge, particularly from the distal end. We report a case series where a simple and reproducible technique of extracting broken femoral cannulated nails using a ball-tipped guide wire is described. This closed technique involves no additional equipment or instruments. MATERIALS AND METHODS: Eight patients who underwent the described method were included in the study...

OBJECTIVES: In 2004, we modified our technique for the stabilization of femoral shaft fractures so that all fractures were stabilized using a reconstruction nail with proximal locking screws oriented into the femoral head. The rationale for this was twofold: first, potentially "missed" associated femoral neck fractures would be stabilized. Second, hip fractures that might occur later in life above the intramedullary nail might be avoided. The purpose of this study therefore was to determine whether there were any risks to patients treated for femoral shaft fractures with antegrade nails using cephalomedullary proximal locking screws...
