Abstract

Because of the known tendency for early redislocation following open reduction, we developed surgical methods for shortening the ligamentum teres to improve immediate postoperative stability when performing medial approach open reduction (MAOR) for the management of developmental dysplasia of the hip. Between 2004 and 2014, 32 patients with dysplasia of the hip were managed by MAOR with partial excision and plication of ligamentum teres. The patients were followed up for an average of 6.9 years. At the final follow-up, clinical outcomes achieved were categorized as excellent and good in 39 (39/40; 97.5%) hips. At the latest follow-up, 97.5% (39 hips) were classified as good or excellent on the basis of the Severin classification (Severin grade 1 or 2). In conclusion, this series of MAOR, in which ligamentum teres partial excision and plication was utilized, we found stable reduction in all hips. On the basis of these positive results, we recommend this method for children treated with MAOR.

Level of evidence: IV, case series.

Surgical technique

The approach is similar to that described by Weinstein and Ponseti [10]. A 3 cm incision is made parallel to and 1 cm distal to the groin crease, centered on the adductor longus. The tendon of the adductor longus is divided, close to the pubic tubercle, and allowed to retract. The anterior branch of the obturator nerve is then identified and traced between the adductor brevis and the pectineus. When this interval is developed, the medial circumflex vessels can be identified and protected by gentle retraction. The psoas tendon is divided at its insertion to the lesser trochanter, and the capsule is opened in a T-fashion. Care was taken to ensure that the long limb of the T continued beneath the vessels as far as the synovial reflection. The ligamentum teres is identified and retracted, the bulk of the pulvinar is cleared, and the limbus is everted if necessary. The femoral head is then delivered into the acetabulum and the ligamentum teres is divided into two halves. One half is excised and the other half is sutured side-to-side by 1.00 vicryl sutures (Fig. 1). The incision is closed in layers. Bilateral cases were operated in the same sitting. A double hip spica is applied with the hips flexed 100° and abducted 40°–60°, for 12 weeks, changed under general anesthesia after 6 weeks. Plain radiographs confirmed the quality of the reduction.

Tiktaalik roseae

  TIKTAALIK ROSEAE The first truly tetrapod animal (Limbed tetrapods) is recognized as the lobe-finned fish Tiktaalik roseae (clade Elpistostegalia), discovered in rocks aged about 375 Ma (2006DaeschlerEB_JenkinsJrFA; 2008ShubinN; 2017ShubinN). Discoveries in recent years have allowed us to place the taxa of early tetrapodomorphs in the following order: Tinirau, Eusthenopteron, Megalichthys, Panderichthys, Qikiqtania, Tiktaalik, Elpistostege, Parmastega, Ventastega, Acanthostega, Elginerpeton, Ymeria, Ichthyostega (2022StewartTA_ShubinNH).

Homo ergaster

  HOMO ERGASTER The Homo ergaster species lived in Africa 1.8 million years ago and was alive until 600,000 years ago, likely becoming the ancestor of Homo erectus in Asia, Homo neanderthalensis in Europe, and Homo sapiens in Africa (1995CachelS_HarrisJ; 2005KleinR). Homo ergaster is occasionally equated with Homo erectus in publications (2013TattersallI). The most complete Homo ergaster skeleton belongs to an adolescent named "Turkana Boy" (KNM-WT 15000). The young man was between 8 and 12 years old (2010GravesRR_CunninghamDL; 2019BergmanJ). The age of this individual's remains is believed to be 1.6 million years (2007TattersallI).

[In Russian]  Chapter 10. THE ARK AND THE CAVE The Book of Genesis does not specify where Noah lived before the flood, but it is plausible his home was in the "land of Nod." To save his family and terrestrial animals, Noah builds an ark measuring "three hundred cubits" long, "fifty cubits" wide, and "thirty cubits" high, coated with pitch inside and out. The vessel has three decks, a pyramidal roof, a side door, and a window, likely at the top. Noah loads his wife, three sons with their wives, and representatives of birds, reptiles, and "clean and unclean cattle." The text lists some "passengers": Noah’s sons, Shem, Ham, and Japheth, and mentions "beasts," "cattle," "creeping things," "flying creatures,"...

1878MarshallJ

  Fragments from the book Marshall J. Anatomy for artists (1878). The author discusses the anatomy and briefly the role of the ligamentum capitis femoris (LCF): «… checks adduction of the thigh, or a sinking down of the pelvis upon the opposite side, and, possibly, also limits the reciprocal, horizontal rotatory movements of the femur and the pelvis on each other» .   Quote p. 65 The head of the femur is almost entirely received into the acetabulum, a deep socket of the hip-bone, thus forming the largest and most complete ball-and- socket joint in the body. At a point on the inner side of the head of the femur, a little below and also behind its centre, is a small rough, bifid , depression, for the attachment of the ligamentum teres of the hip-joint. Opposite this point, the head of the bone is, however, more prominent than elsewhere, and corresponds with a non- articular depressed portion of the acetabulum.   Quote p. 68 The ligamentum teres, which is attached by one en...
