Emergent Management of Traumatic Posterior Sternoclavicular Joint Dislocation: A Case Report and Literature Review.

Sternoclavicular joint (SCJ) dislocation is a rare but serious orthopedic injury. Posterior dislocations are more concerning due to the SCJ's proximity to visceral structures such as the trachea, esophagus, subclavian vessels, and brachial plexus. Due to the potential long-term sequelae of missed diagnosis, clinical suspicion should be high when a patient presents with a compression-type injury to the shoulder girdle and pain or deformity to the SCJ.

Real time eye blink noise removal from EEG signals using morphological component analysis.

This paper presents a method of removing the noise caused by eye blinks from an electroencephalogram (EEG) signal in real time based on morphological component analysis (MCA). This method sparsely represents both the eye blink and the EEG signal basis matrices using a Short Time Fourier Transform (STFT). This approach has two main advantages: 1) fast computation of the estimation of the signal coefficients using the basis pursuit algorithm 2) less memory requirement.

Complications and vascular salvage of free-tissue transfers to the extremities.

Complications were examined in 122 free flaps to lower and upper extremities in 104 patients, and vascular salvage was examined in 182 free flaps to lower and upper extremities in 158 patients. All patients were treated by the same surgeon. The overall survival rate of flaps was 96 percent.

Venous flaps in digital revascularization and replantation.

This is a report on 15 patients who underwent replantation/revascularization of a single digit with a substantial dorsal soft tissue defect. The dorsal defect was covered with a venous flap, a free flap that has only venous inflow and outflow. Postoperatively, the venous flaps were warm, pink, and appeared to exhibit a blanch and refill phenomenon, clinically resembling capillary filling.

Posterior shoulder approach.

A posterior shoulder surgical approach combines the subperiosteal detachment of the deltoid from the scapular spine, described by McWhorter, with a lateral extension to include the lateral deltoid splitting of Codman. The glenohumeral joint is superiorly approached between the supraspinatus and infraspinatus tendons, or inferiorly between the infraspinatus and teres minor tendons. This approach was used in 42 shoulders with rotator cuff tears or posterior instability without complications of infection, failure of deltoid healing, or compromise of suprascapular or axillary nerves.

External fixators for wrist fractures: a biomechanical and clinical study.

The rigidity of four external fixators for the wrist was determined by using the Instron universal testing instrument. Using the equivalent stiffness index, the small A.O.
