Popliteal artery injury is a very rare complication of anterior cruciate ligament (ACL) reconstruction. The authors experienced a case of popliteal arterial pseudoaneurysm after re-revision of ACL reconstruction using Rigidfix for femoral tunnel fixation. Pseudoaneurysm was detected in knee magnetic resonance imaging, which caused pain, limit of motion, common peroneal nerve palsy, leg swelling...

Background Extirpation of aggressive parotid or cutaneous facial tumors often involves facial nerve sacrifice and the creation of a large soft-tissue defect. We describe a method for single-stage reconstruction during radical parotidectomy to restore facial form and function without additional morbidity. Methods We conducted a review of immediate reconstruction/reanimation of radical parotidect...

Background Phrenic nerve reconstruction has been evaluated as a method of restoring functional activity and may be an effective alternative to diaphragm plication. Longer follow-up and a larger cohort for analysis are necessary to confirm the efficacy of this procedure for diaphragmatic paralysis. Methods A total of 180 patients treated with phrenic nerve reconstruction for chronic diaphragmati...

PURPOSE Glaucoma is a common ocular disease whose pathogenesis is hypothesized to involve biomechanical damage to optic nerve tissues. Here we describe a method for the construction of patient-specific models that can be used to evaluate the biomechanical environment within the optic nerve head. We validate the method using a virtual eye, and demonstrate its use in computing optic nerve head bi...

OBJECTIVE To evaluate clinician perception of voice quality, patient self-reported psychosocial impact of dysphonia, and glottic closure in patients who have undergone resection of the recurrent laryngeal nerve (RLN) and immediate operative reconstruction during thyroid surgery. STUDY DESIGN Prospective observational study. SETTING Single tertiary care hospital. SUBJECTS AND METHODS Nine ...

Background: Injury to the infrapatellar branch of the saphenous nerve (IPBSN) is common after arthroscopic ACLreconstruction with hamstring tendon autograft, as reported in up to 88% of the cases. Due to close relationshipbetween the IPBSN with pes anserine tendons insertion skin incision may sever IPBSN while harvesting gracillis andsemitendinous tendons. As the IPBSN course at the anterior of...

Peripheral nerve long gap defects are a clinical challenge in the regeneration field. Despite the wide variety of surgical techniques and therapies, autografting is the "gold standard" for peripheral nerve gap reconstruction. The pathological process of Wallerian degeneration from the time of acute injury to efficient regeneration requires several weeks. Regeneration time is critical for nerve ...

We present a case of disruption of the posterolateral corner of the knee with avulsion of the tendon of biceps femoris. Repair and reconstruction included an allogenic tendon graft to replace the posterior cruciate ligament. Surgery was followed by a complete common peroneal nerve palsy. Revision surgery revealed that the nerve had been displaced anteriorly by avulsion of the biceps tendon and ...
