“…The role of the tendon sheath has received significant attention in the process of improving the effect of the repaired flexor digitorum tendon in zone II[ 16 ]. The current view is that the tendon sheath is not only the supporting tissue of the tendon but also has nutritious and auxiliary sliding effect on the tendon.…”

The adhesion of tendon and surrounding tissue is the most common complication after repairing an injured tendon. The injured flexor tendons in zone II are frequently accompanied by tendon sheath defects, which lead to poor recovery. A variety of biological and non-biological materials have been recently used for repair or as substitute for tendon sheaths to prevent tendon adhesion. However, non-biological materials, such as polyethylene films, have been used to prevent tendon adhesions by mechanical isolation. The possibility of tendon necrosis and permanent foreign body remains due to the lack of permeability and the obstruction of nutrient infiltration. The natural macromolecule amniotic membrane derived from organisms is a semi-permeable membrane with the following characteristics: smooth; without vascular, nerve, and lymphatic; and rich in matrix, cytokines, enzymes, and other active ingredients. The unique structure of this membrane makes it an ideal biomaterial. In the experiment in Henry chicken, the model of tendon sheath defect and the flexor digitorum tendon in zone II was established and randomly divided into control group, medical membrane group, and decellularized amniotic membrane group. Samples were obtained at the 2nd, 4th, 8th, and 12th week after operation. General, histological, and biomechanical tests were performed to investigate the preventive effect of repaired tendon sheath by decallularized amniotic membrane. Experimental results showed the following: the amniotic membrane group and the medical membrane group had mild inflammatory reaction and tissue edema, and nearly no adhesion was observed in the surrounding tissue; the fibroblast-like cells were distributed in layers under the light microscope; the amniotic membrane group was denser than the medical membrane group cells, and numerous fibroblasts were disorganized in the control group. Biomechanical measurements showed that the sliding distance of tendon, the total flexion angle of the toes, and the tendon maximum tensile breaking strength at the early postoperative were significantly better than in the control group. Through this experiment, the amniotic membrane, as a natural biological substitute material in the construction of tendon sheath, can effectively inhibit exogenous healing and promote endogenous healing to prevent tendon adhesion.

Aim. To trace developmental origins of surgical treatment of hammertoe deformity and determine the most commonly used methods of its correction based on the published literature analysis. Material and methods. Publications from Google search, electronic databases PubMed, Google Scholar, archives of specialized journals and other relevant sources of scientific and medical information were analyzed. Results. The article covers the developmental origins of surgical treatment of hammertoe deformity both in the historical aspect and at the current level. Attention is paid to soft tissue procedures including tendons, metatarsophalangeal joint capsule, and plantar plate. An overview of operative interventions on the bone apparatus, phalanges and metatarsal bones and the combination of these surgeries is also presented in the article. The disadvantages of the existing surgical treatments, their advantages and the ways for forthcoming research concerning the improvement of surgical care in the treatment of hammertoe deformity are identified. Conclusions. The choice of a particular method of surgical correction between the phalangeal or metatarsal level, the feasibility of combining these interventions with restoring the integrity of the plantar plate and tendon reconstruction, remains debatable. Further study on these issues is a crucial task today for choosing the optimal method of hammertoe deformity correction.

“…26 Within the past few years, surgeons have begun focusing on performing anatomic repairs of plantar plates 24,27,38,40 to treat dorsal MTP joint instability. 2,4,8,33 Plantar approaches to the plantar plate have been described 13,24 ; however, this approach is not preferred because of the extensive dissection through the plantar fat pad and flexor tendons to gain access to the plantar plate, concerns for scar formation on the plantar surface of the foot, as well as pain associated with weight bearing on a plantar incision. Instead, dorsal approaches to the plantar plate have been popularized recently as the plantar plate can be accessed through the MTP joint.…”
