[Variations in the calcaneo-fibular ligament (lig. calcaneofibulare). Application to the kinematics of the ankle].

The authors observe variations in the calcaneo-fibular ligament because this ligament controls two articulations, the talo-crural and the subtalar. This study is based on the dissection of the ankle of 20 specimens. The calcaneo-fibular ligament is reinforced by the ventral and lateral talo-calcaneus ligaments with variations. 3 types of disposition have been described. Type A: A lateral talo-calcaneal ligament reinforces the calcaneo-fibular ligament. These two ligaments are divergent on the proximal, medial, or distal part. Type B: There is an independent lateral talo-calcaneal ligament forward of the calcaneo-fibular ligament. Type C: A ventral talo-calcaneal ligament is observed, parallel to the interosseous ligament. The authors consider the consequences of variation in the lateral ligaments of the ankle for the functioning of the tibio-tarsal articulation, the subtalar articulation and the astragalo-scaphoid articulation in order to propose specific radiographic examination of the kinematics of the ankle.

Anatomic basis of a superior approach to the acetabulum with osteotomy of the ala of the ilium.

This study demonstrates the importance of a superior approach to acetabulum with intrapelvic osteotomy of the iliac ala in certain fractures of the acetabulum. This study is based on the dissection of 15 formolized and 5 frozen subjects, the surgical treatment of 17 acetabular fractures, and the performances of 2 Chiari-type osteotomies and 2 Salter-type osteotomies. We investigated the gluteus medius muscle and its pedicle in relation to the iliac ala. Landmarks for the osteotomy lines and the gluteal pedicles are defined in terms of the requirements of different surgical approaches. The superior approach for acetabular fractures was made using a skin incision of Smith-Petersen type. The underlying principle is the performance of an intrapelvic osteotomy of the iliac ala, the anterosuperior part of the ala being tilted outward and backward and pedicled on the gluteal muscles. This provides intra- and extrapelvic exposure of the acetabular walls. The advantages and drawbacks of this route of approach in surgery of the pelvic girdle are discussed in terms of the types of fracture treated and tumoral locations. The anatomic findings are illustrated from traumatology and tumoralpathology. This approach seems particularly suitable for acetabular fractures interrupting the pelvic ring.

Extensor tendon injuries. Presentation of a series of ninety-nine cases.

A series of 99 cases of injuries of the extensor system, followed in the 3 Traumatology and Orthopedics Ward (Dijon, France) is presented. Results were analyzed according to Verdan's classification. In most cases, a Jenning "barb-wire" type repair, introduced in France by Y. Allieu, was made. Early mobilization and skin tension problems are emphasized; two cases of degloving on the dorsum of the hand are presented with details. As well, a special place concerning the results of repair in the proximal interphalangeal joint must be reserved, because of the very frequent association of articular destruction and the very difficult problem s of surgical management which arise in these cases.

[Study of the vascular segmentation of the spleen].

An experimental study of the spleen segmentary vascularisation was conducted by the "injection-corrosion" technique. Most often was found the well known existence of two lobes, each being divided into two segments, separated by asvascular planes. However we stress the possibility of deviation from this schema, either by the existence of supernumerary polar arteries, or by anomalies in the distribution of segmental arteries.

[Morphological study of the muscle of Treitz (m. suspensorius duodeni)].

The differences of opinion concerning the morphology of the human suspensory muscle of the duodenum conducted the authors to perform a study upon 31 cadavers including 21 adults and 10 foetuses. In most cases they describe a single muscle arising from the duodeno-jejunal flexure and reaching the right side of the diaphragm oesophageal opening. Microscopic examination confirms that it consists of unstriped muscle fibers except cranially near from his diaphragmatic insertion where striped muscle fibers can be observed.
