Injury To The Posterior Horn Of The Lateral Meniscus From A Misplaced Tibial Tunnel For Anterior Cruciate Ligament Reconstruction: A Case Report, Amar S Vadhera, Jonathan S Lee, Harsh Singh, Safa Gursoy, Kyle N Kunze, Nikhil N Verma, Jorge Chahla

Department of Orthopaedic Surgery Faculty Papers

BACKGROUND Posterior meniscal root avulsions can cause meniscal extrusion, joint space narrowing, and progressive knee arthritis. Iatrogenic posterior meniscal root avulsions after malpositioning of the transtibial tunnels during anterior cruciate ligament (ACL) reconstruction can account for poor long-term outcomes seen in some patients following ACL reconstruction. Therefore, correct transtibial tunnel placement during ACL reconstruction is essential to avoid iatrogenic meniscal damage. CASE REPORT A 32-year-old man presented with 1 year of right knee pain and instability following a non-contact twisting injury sustained while playing soccer. An ACL tear with no meniscal involvement was diagnosed at an outside institution. A double-bundle …

Household Transmission Of Group A Streptococcus Necrotizing Fasciitis., Michael Markowitz, Stephanie Kwan, Jonas Matzon

Department of Orthopaedic Surgery Faculty Papers

A healthy 40-year-old woman was diagnosed with necrotizing fasciitis 2 days after her husband's death from the same infectious process. Prompt identification and immediate surgical intervention prevented a similar result in this patient. Additional investigation into both patients' medical records found the inciting organism to be group A streptococcus. Although the exact mechanism of inoculation is unknown, the spread of this infection within a household prompts the question of whether antibiotic prophylaxis should be given among close contacts in future cases of necrotizing fasciitis.

Department of Neurology Faculty Papers

Degenerative cervical myelopathy (DCM) is the most common cause of spinal cord dysfunction in adults. Its prevalence is increasing as a result of population aging. The diagnosis of DCM is often delayed or overlooked, resulting in secondary neurologic morbidity. The natural course of DCM typically presents as a gradual neurological deterioration, with symptoms ranging from muscle weakness to complete paralysis, with variable degrees of sensory deficits and sphincter dysfunction. Magnetic resonance imaging (MRI) and electrophysiological studies allow the assessment of spinal cord function and its structural damage to determine treatment and clinical outcomes. All patients with signs and symptoms consistent …

A Standardized Comparison Of Peri-Operative Complications After Minimally Invasive Esophagectomy: Ivor Lewis Versus Mckeown., Andrew M. Brown, Michael J. Pucci, Adam C. Berger, Talar Tatarian, Nathaniel R. Evans Iii, Ernest L. Rosato, Francesco Palazzo

Department of Surgery Faculty Papers

BACKGROUND: While our institutional approach to esophageal resection for cancer has traditionally favored a minimally invasive (MI) 3-hole, McKeown esophagectomy (MIE 3-hole) during the last five years several factors has determined a shift in our practice with an increasing number of minimally invasive Ivor Lewis (MIE IL) resections being performed. We compared peri-operative outcomes of the two procedures, hypothesizing that MIE IL would be less morbid in the peri-operative setting compared to MIE 3-hole.

METHODS: Our institution's IRB-approved esophageal database was queried to identify all patients who underwent totally MI esophagectomy (MIE IL vs. MIE 3-hole) from June 2011 to …
