“…In a comparative study of six absorbable and four non-degradable sutures implanted circumferentially under the skin of rats, silk lost 55% of its tensile strength and 16% of its elastic modulus 6 weeks postimplantation [57] (Table 6). In a rat model with subcutaneous implantation, silk fibers lost 29% of their tensile strength at 10 days, 73% at 30 days and 83% 70 days post-implantation (Table 7) [45].…”

Silk from the silkworm, Bombyx mori, has been used as biomedical suture material for centuries. The unique mechanical properties of these fibers provided important clinical repair options for many applications. During the past 20 years, some biocompatibility problems have been reported for silkworm silk; however, contamination from residual sericin (glue-like proteins) was the likely cause. More recent studies with well-defined silkworm silk fibers and films suggest that the core silk fibroin fibers exhibit comparable biocompatibility in vitro and in vivo with other commonly used biomaterials such as polylactic acid and collagen. Furthermore, the unique mechanical properties of the silk fibers, the diversity of side chain chemistries for 'decoration' with growth and adhesion factors, and the ability to genetically tailor the protein provide additional rationale for the exploration of this family of fibrous proteins for biomaterial applications. For example, in designing scaffolds for tissue engineering these properties are particularly relevant and recent results with bone and ligament formation in vitro support the potential role for this biomaterial in future applications. To date, studies with silks to address biomaterial and matrix scaffold needs have focused on silkworm silk. With the diversity of silk-like fibrous proteins from spiders and insects, a range of native or bioengineered variants can be expected for application to a diverse set of clinical needs. r

Three patients with malignant bone tumors of the proximal femur underwent implantation of an endoprosthesis with reconstruction of the joint capsule and hip abductors using artificial mesh.Résumé 3 patients opérés pour tumeur maligne de l'extrêmité proximale du fémur ont eu l'implantation d'une endo-prothèse avec reconstruction de la capsule articulaire et des abducteurs par un filet synthétique.

“…The first stage starts from the day of the operation to the day of the cast removal (four weeks). During this period, the full tensile strength of the reinforcement suture protects the repair [3,5,20]. Thus, isometric quadriceps exercises are instituted and walking in plaster is allowed as tolerated.…”

“…During this period, the reinforcement suture has lost its tensile strength [5]; thereby, the recommended biomechanical loading [1,4,17,18] is possible. A programme of straight leg rising and active flexion exercise is instituted.…”

The reported complications of the repaired patellar tendon have been attributed to the influence of the mechanical environment on the healing process. This study postulates that the healing complications can be minimised through tension regulation at the suture line using an absorbable reinforcement device. Twelve patients with fresh patellar tendon rupture were included in the study. They were prospectively followed up for an average period of 45 months. The patients resumed their pre-injury activities at an average of 6.1 months. The active knee movement averaged 0-154.6°compared to 0-156.7°in the contralateral knee. Radiologically no patella alta, patella baja or degenerative changes in the patellofemoral joints were noted. The results support use of the absorbable reinforcement device for tension regulation at the suture line.
