Accessory Palmaris Longus: A Concise Anatomic Review With a Relevant Case Study.

Current medical literature has described many variations of the palmaris longus. One variation that is rarely seen is that of the accessory palmaris longus, which is better known in literature as the "palmaris profundus." This brief review will describe the anatomy and the developmental origins of the palmaris longus, as well as the clinical relevance of an accessory palmaris longus. We will also present a case on the accessory palmaris longus and discuss whether the accessory palmaris longus, if encountered during a routine carpal tunnel surgery, should be resected intraoperatively.

Outcomes are favorable in Asian patients undergoing deltoid-on open rotator cuff repair without acromioplasty.

BACKGROUND: To evaluate if rotator cuff repair without acromioplasty would result in improvement in outcomes without the risks associated with acromioplasty in Asian patients. METHODS: 38 primary repairs of tears of the rotator cuff were performed through a deltoid-on approach. The Simple Shoulder Test (SST) and UCLA shoulder rating scale were measured preoperatively and at 2 years post-operatively. RESULTS: There was a significant improvement in the SST 2 years post-operatively (p < 0.001). UCLA scores for pain control and function (p < 0.001) also significantly improved 2 years post-operatively. CONCLUSION: Outcomes are favorable in Asians following deltoid-on open rotator cuff repair without acromioplasty. LEVEL OF EVIDENCE: III.

Incidence of clinically significant venous thromboembolic events in Asian patients undergoing total knee arthroplasty without anticoagulation.

This study aimed to evaluate the incidence of clinically significant venous thromboembolic events (VTE) in Asian patients undergoing total knee arthroplasty (TKA) without anticoagulation. All patients who underwent TKA by a single surgeon from 2006 to 2010 in Singapore General Hospital were reviewed. Only symptomatic patients were referred for ultrasonography. Of the 531 patients reviewed, 3 patients developed symptoms of deep vein thrombosis with subsequent ultrasonographic confirmation, whereas 1 patient developed fatal pulmonary embolism without any clinical or radiologic evidence of deep vein thrombosis. Hence, the incidence of clinically significant VTE was 0.75%. Given the low incidence of clinically significant VTE, there is a need to review the current practice of routine chemoprophylaxis in Asian patients undergoing TKA.
