Purpose To compare the efficacy of intraocular pressure (IOP) control Baerveldt-350 implant with tube ligature and Ahmed valve in patients refractory glaucoma. Patients Methods Four hundred seventy glaucoma drainage device procedures from July 1995 to 2001 (6 years) were reviewed retrospectively. Thirty-two cases implantation performed medical treatment filtering procedures, without previous or cyclodestructive a minimum 1-year follow-up identified. matched case by 32 for age, race, gender,...

Intraarticular injections of corticosteroids combined with local anesthetics are commonly used for management chronic pain symptoms associated degenerative joint diseases and after arthroscopic procedures. Several studies suggest chondrotoxicity whereas others report chondroprotective cytotoxic effects on cartilage. Given the frequency use these agents, it is important to know whether they in fact toxic.We asked (1) bupivacaine triamcinolone acetonide, alone combined, were chondrotoxic...

INTRODUCTION: Endoscopic sagittal suturectomy (ESS) is commonly indicated for craniosynostois in infants, but optimal timing of surgery remains controversial with many clinicians only offering ESS before 3 months age. METHODS: A single center retrospective review patients craniosynostosis that underwent between 2009-2023 at Children’s National Medical Center was performed. Patients were stratified by age to compare outcomes and transfusion rates. Receiver operating curve (ROC) area under the...

Case: Isolated avulsion of the teres minor tendon is exceedingly uncommon and, to our knowledge, presentation and arthroscopic repair this type injury have not been described. Known musculotendinous avulsions about shoulder frequently involve supraspinatus, long head biceps, pectoralis major. Conclusion: We present case a patient with an isolated otherwise intact rotator cuff. The underwent successful rehabilitation, allowing for return pre-injury level function.

Soft tissue fluid retention is a common problem after arthroscopy, with as much 2% of patients having complications develop. A fenestrated outflow cannula has been introduced to reduce interstitial swelling. We tested the ability this design weight gain. enrolled 28 undergoing shoulder arthroscopy and randomized them into two groups using versus conventional cannulae. The group had greater gain function procedure duration than (slope = 0.542 +/- 1.160 kg/hour 0.0144 0.932 kg/hour). also...
