The effect of surgical timing on the outcome of patients with neck of femur fracture.
To investigate the effect of surgical timing (in hours versus after hours and weekdays versus weekends) on the outcome of patients with neck of femur fracture. ⋯ There was no difference in the rates of adverse events between patients who had surgery during hours and weekdays with those who had surgery after hours or weekends. The careful selection of patients with appropriate hospital staff, resources and adequate theatre access, surgery during after hours and weekends may be safely considered to prevent a delay in surgical treatment for patient with neck of femur fracture.

Gap-balancing technique combined with patient-specific instrumentation in TKA.
Combining patient-specific instrumentation (PSI) with a balancer device in total knee arthroplasty (TKA) to achieve functional femoral rotational alignment is a novel technique. The primary goal of this study was to introduce a new method to combine PSI with a gap-balancing technique and to determine the impact of the technique on rotation of the femoral component. ⋯ PSI was with the gap-balancing technique was successfully used without affecting anatomical alignment. With the balancer device, PSI can be used more widely than techniques based solely on landmarks, as the soft-tissue tension can be taken into account, thus virtually eliminating flexion instabilities.

Platelet-rich plasma did not improve early healing of medial collateral ligament in rats.
The medial collateral ligament (MCL) is the most frequently injured ligament of the knee. Platelet-rich plasma (PRP) is a relatively new treatment option developed to enhance the healing response after injury to different tissue types. This study aimed at investigating whether the addition of PRP to MCL tears in rats would alter healing both biomechanically and histologically. ⋯ The addition of PRP to a healing MCL did not improve any of the outcome measures in this model.

Sonographical parameters of the finger pulley system in healthy adults.
To establish normative values of tendon to bone distances (TBDs) to evaluate the A2 and A4 annular pulley integrity, we hypothesized that these values correlate with gender, athletic exercise, occupation, individual's age and body height. ⋯ Establishing normative values will help to detect injured pulleys more precisely and examination should be performed both in resting position and active forced flexion.

Radial nerve location at the posterior aspect of the humerus: an anatomic study of 100 specimens.
Radial neuropathy represents a devastating complication in a posterior approach to the distal humerus. This study aimed to propose "safe zones" regarding the radial nerve (RN) location at the posterior aspect of the humerus to minimize the risk of iatrogenic injury. ⋯ We present the OF as an osseous landmark to reduce the risk of iatrogenic radial neuropathy. HL and TW can be reliably used to estimate the RN location. The consistent "safe zones" of the RN in relation to the OF are 10.5 cm at the medial edge, 9 cm at the center and 7.5 cm at the lateral edge of the posterior aspect of the humeral shaft.
