Inside-out Medial Meniscal Repair: Improved Surgical Exposure With a Sub-semimembranosus Approach.

Arthrosc Tech 2021 Feb 16;10(2):e507-e517. Epub 2021 Jan 16.

Department of Orthopaedic Surgery, Washington University School of Medicine, St Louis, Missouri, U.S.A.

Inside-out meniscal repair is considered the gold standard for reparable tears of the medial and lateral menisci despite the recent popularity of all-inside devices. Accurate suture passage is required to perform a stable repair as well as to prevent inadvertent neurovascular injury from the suture needles. Placement of a deep soft-tissue retractor is necessary to identify and retrieve these needles prior to tying the sutures. Read More

A Murine Model of Ischemic Retinal Injury Induced by Transient Bilateral Common Carotid Artery Occlusion.

J Vis Exp 2020 11 12(165). Epub 2020 Nov 12.

Laboratory of Photobiology, Keio University School of Medicine; Department of Ophthalmology, Keio University School of Medicine;

Diverse vascular diseases such as diabetic retinopathy, occlusion of retinal veins or arteries and ocular ischemic syndrome can lead to retinal ischemia. To investigate pathological mechanisms of retinal ischemia, relevant experimental models need to be developed. Anatomically, a main retinal blood supplying vessel is the ophthalmic artery (OpA) and OpA originates from the internal carotid artery of the common carotid artery (CCA). Read More

Capsulorrhaphy using suture anchors in open reduction of developmental dislocation of hip: technical note.

J Pediatr Orthop B 2021 Mar;30(2):150-153

Barts and London School of Medicine and Dentistry, Queen Mary University of London, London, UK.

We describe a new technique of using titanium alloy anchors to perform internally rotating capsulorrhaphy during open reduction and stabilization procedure and obliteration of pseudoacetabulum when one exists. We routinely use anterior approach via bikini incision (modified Smith-Peterson approach) to perform open reduction and internally rotating capsulorrhaphy. We describe the technique of using barbed titanium alloy anchors preloaded with nonabsorbable sutures and two needles, to accomplish a secure and easy capsulorrhaphy, in selected cases. Read More

Anatomic relationship of the sural nerve when performing Achilles tendon repair using the percutaneous Achilles repair system, a cadaveric study.

Foot Ankle Surg 2020 Jun 7. Epub 2020 Jun 7.

Valley Hospital Medical Center, Department of Orthopedic Surgery, 620 Shadow Lane, Las Vegas, NV, 89106, United States.

Background: Minimally invasive techniques for Achilles tendon repair are increasing due to reports of similar rerupture rates using open and percutaneous techniques with fewer wound complications and quicker recovery with percutaneous methods. The goal of this study was to investigate quantitatively the relationship and risk of injury to the sural nerve during Achilles tendon repair when using the Percutaneous Achilles Repair System (PARS) (Arthrex®, Naples, FL), by recording the distance between the passed needles and the sural nerve as well identifying any direct violation of the nerve with needle passage or nerve entrapment within the suture after the jig was removed. The hypothesis of the study is that the PARS technique can be performed safely and without significant risk of injury to the sural nerve. Read More

Vasoepididymostomy: an insight into current practice patterns.

Transl Androl Urol 2019 Dec;8(6):728-735

Scott Department of Urology, Baylor College of Medicine, Houston, TX, USA.

Background: Vasectomy reversal (VR) is a specialized procedure currently offered by an increasing number of medical practitioners. One method of VR, vasoepididymostomy (VE), is considered the most challenging microsurgical technique within the field of reproductive urology. We surveyed reproductive urologists to assess current practice patterns regarding both intra-operative and post-operative considerations surrounding VE, with the hypothesis being that more experienced surgeons may have different practice patterns than less experienced surgeons.

Editorial Commentary: Caveat Medicus-Beware of Meniscal Repair.

Authors:
Mark D Miller

Arthroscopy 2020 02;36(2):499-500

University of Virginia.

Perform meniscal repair with care and beware! Because of the well-known adverse consequences of meniscectomy, especially in the lateral compartment, meniscal repair should be considered for every meniscal tear even if it requires pushing the envelope. Nevertheless, the surgeon must be keenly aware of neuromuscular risks associated with this technique. For the posterior horn of the lateral meniscus, extreme caution must be exercised, particularly in younger and presumably smaller female patients. Read More

Department of Surgical and Perioperative Sciences, Division of Surgery, Umeå University, Sunderby Research Unit, Umeå, Sweden.

Our aim was to determine if a newly designed Najar needle holder (NNH) shortens the time for novices to improve advanced laparoscopy (AL) techniques (suturing/knot tying), compared with a conventional macro needle holder (MNH) in a simulator. Furthermore, we aimed to validate a new video scoring system determining AL skills. Forty-six medical students performed identical surgical tasks in a prospective, crossover study evaluating AL skills (NNH vs MNH). Read More

Double Row-Equivalent PASTA Repair Technique.

Arthrosc Tech 2019 Aug 1;8(8):e905-e910. Epub 2019 Aug 1.

Department of Orthopaedic Surgery, Tulane University School of Medicine, New Orleans, Louisiana, U.S.A.

Articular surface partial rotator cuff tendon tears are a common source of shoulder pain and dysfunction, and there is no consensus regarding the optimal arthroscopic treatment. Commonly accepted techniques, such as transtendinous repair or tear takedown with primary repair, may violate healthy tendon tissue and increase the suture anchor density. In this note, we describe an outside-in double row-equivalent technique for repair of partial articular-sided rotator cuff tears. Read More

Sutureless intrascleral fixation of intraocular lens through self-sealing sclerotomy wounds using haptic externalization and reinternalization technique.

J Cataract Refract Surg 2019 10;45(10):1367-1371

McGill University, Montreal, Quebec, Canada. Electronic address:

In eyes with absent or insufficient capsule support, three-piece posterior chamber intraocular lens (PC IOL) may be fixed to the sclera. Previous techniques involve the use of sutures, flaps, glue, needles, trocars, or intrascleral tunnels to fixate the distal tips of the haptics intrasclerally. Herein we describe a modified technique for the sutureless scleral fixation of a standard 3-piece PC IOL using self-sealing sclerotomies created with a crescent blade and a 20-gauge microvitreoretinal blade, and then reinserting the haptics to leave the tips inside the vitreous cavity.

World J Surg 2020 01;44(1):95-99

Department of Surgery, Skåne University Hospital, University of Lund, Jan Waldenströms gata 5, 205 02, Malmö, Sweden.

Introduction: A laparotomy is commonly required to gain abdominal access. A safe standardized access and closure technique is warranted to minimize abdominal wall complications like wound infections, burst abdomen and incisional hernias. Stitches are recommended to be small and placed tightly, obtaining a suture length-to-incision length (SL/WL) ratio of ≥ 4:1. Read More
