Effect of physiological posterolateral rotatory laxity on early results of posterior cruciate ligament reconstruction with posterolateral corner reconstruction.

Background: The purpose of this study was to evaluate the influence of physiological posterolateral rotatory laxity on posterior cruciate ligament (PCL) reconstruction in terms of posterior stability and clinical outcomes.

Methods: We retrospectively reviewed the records of sixty-five patients who had undergone arthroscopic PCL reconstruction with simultaneous reconstruction of the posterolateral corner from March 2004 to April 2009. Patients were categorized into three groups according to the amount of tibial external rotation at 90° of knee flexion on the uninjured side: Group 1 (<40°; n = 26), Group 2 (between 40° and 50°; n = 21), and Group 3 (>50°; n = 18).

Evaluation of shoulder disorders by 2-[F-18]-fluoro-2-deoxy-D-glucose positron emission tomography and computed tomography.

Background: Although fluorine-18-fluorodeoxyglucose (FDG) positron emission tomography (PET) has a limitation for localizing anatomical structures, combining it with computed tomography (CT) has made it more efficient for overcoming such limitations. This study aims to evaluate the efficacy of PET/CT for evaluating diseases of the shoulder.

Methods: Retrospective examination was performed on 25 patients who underwent FDG-PET/CT scanning.

The effectiveness of ultrasonography-guided suprascapular nerve block for perishoulder pain.

This study analyzed the effectiveness of suprascapular nerve block under ultrasonographic guidance in patients with perishoulder pain. Patients with perishoulder pain were enrolled in the study and were randomly divided into 2 groups. In the first group of 25 patients (12 men and 13 women), nerve block was applied under ultrasonographic guidance.

Life-threatening posterior circumflex humeral artery injury secondary to fracture-dislocation of the proximal humerus.

Proximal humeral fractures account for 4% to 5% of all fractures, and most of these are minimally displaced and less prone to neurovascular injuries. This article presents a case of a 65-year-old man who injured the posterior circumflex humeral artery following a fracture dislocation of the proximal humerus leading to a life-threatening hemorrhagic complication during surgical fixation of the dislocated proximal humeral fracture. Preoperative vital signs were normal.

Sonographic probe induced tenderness for lateral epicondylitis: an accurate technique to confirm the location of the lesion.

The purpose of this study is to evaluate the hypothesis that ultrasonographic probe-induced tenderness is a useful adjunct to the simple sonography in confirming the location of the pathology within the extensor carpi radialis brevis tendon in patients with lateral epicondylitis of the elbow. We conducted a case controlled study by evaluating 27 consecutive patients in the age group of 37-59 years (median 44) who had typical symptoms of lateral epicondylitis and a visual analogue score of more than 4 and evaluating a same number of asymptomatic healthy volunteers in the age group of 37-59 years (median 43) by means of ultrasound examination of the lateral elbow in a period of 5 months from 2007 to 2008. When we identified sonographic anechoic or hypoechoic lesions within the common extensor tendon we compressed it with the ultrasound probe to elicit tenderness so as to confirm the site of lesion within the affected tendon.

Upper airway compromise by extravasated fluid: a rare complication after arthroscopic repair of atrophic cuff tear.

During arthroscopic procedures, leakage of irrigation fluid into surrounding tissue planes is a frequently noticed phenomenon usually clinically asymptomatic and resolving within 12 hours postoperatively. Although rare, this fluid may produce life-threatening complications such as airway compromise. This article describes a case of upper airway obstruction in a 60-year-old man undergoing arthroscopic repair for an atrophic rotator cuff tear.
