Observational Study
Predictors of falls in recreational snowboard jumping: An observational study.
Jumping is popular in the sport of snowboarding. Epidemiological research has shown an increased risk of injury associated with this activity. Falls are common when jumping and although there is a logical connection between falling and injury occurrence, thus far little attention has been given to factors involved in the jumping-fall relationship. The current study aimed to add to the current knowledge base by identifying predictors of falling during intentional snowboard jumping within terrain park facilities. ⋯ It is likely that jumping will remain popular in snowboarding and thus research efforts should focus on minimising the risk of injury associated with this skill. Reducing the overall incidence of falling, identified in the current study to be high, is a potential area for improvement. The potential for fall risk reduction through technique and decision making changes provides justification for further research in this area.

The aim of this study was to present a modified Murray and Schwarz 2.5-mm Kirschner wire (K-wire) intramedullary (IM) technique for fixation of displaced midshaft clavicle fractures (DMCF), and to compare the differences in treatment outcome of two-part (Robinson 2B.1) and multifragmentary (Robinson 2B.2) DMCF. ⋯ Intramedullary clavicle fixation with a 2.5-mm K-wire is a safe surgical technique. 2B.1 injuries treated with 2.5-mm IM K-wire fixation have relatively improved outcome compared with displaced 2B.2 fractures for both non-union and reoperation rates. There were no occurrences of implant migration with either 2B.1 or 2B.2 injuries, and a non-significant difference in implant irritation was documented with IM K-fixation. The non-union rate with K-wire IM fixation of 2B.1 injuries concords with the published results of other IM devices and thus this technique should be added to the surgeon's armamentarium when considering surgical treatment of such injuries.

Major lower limb amputation significantly increases the energy cost of walking for patients. Complications such as osteomyelitis may require further surgery, and can lead to shortening of the stump. In these cases, the aim should be to treat infection without shortening the limb further. We present a series of patients with established osteomyelitis of the amputation stump, managed using a modified Lautenbach technique. ⋯ We believe that this case series is the largest so far published regarding this modification of the Lautenbach Procedure. This operation treats infection effectively without further loss of bone length, and no patients so far have developed significant complications.

Evaluate the results of treatment of subtrochanteric fracture with interlocked intramedullary nail and describe a technical for accurate and secure verification of distal locking position when we do surgery without arc-C. ⋯ Although this series consists in a few numbers of patients, we recommend the placement of interlocked intramedullary nail (Closs-MB Bioimpianti® and Orthosintese®) in subtrochanteric fractures. This device allows placement of distal locking through the insertion frame with safety and precision, even in surgery rooms without arc-C. The guide-wire stopping method allows the verification of distal locking in an objective, accurate, safe and reproducible way.

Comparative Study
MIPO of proximal humerus fractures through an anterolateral acromial approach. Is the axillary nerve at risk?
It is known that shoulder surgery may cause iatrogenic injury to the axillary nerve as a serious complication, but there is little evidence to indicate whether the axillary nerve is at risk of injury during an anterolateral acromial approach for minimally-invasive plate osteosynthesis (MIPO) of proximal humerus fractures. We hypothesised that this surgical method is safe for the axillary nerve and would preserve it from iatrogenic injury. ⋯ These results confirmed safety of this surgical method in the preservation of axillary nerve from iatrogenic injury, but the course of the axillary nerve must be kept in mind.
