In this case report, we present the case of a 20-year-old male patient who suffered from pain in walking clinically, and in whom an extremely rare type of brachymetatarsia was diagnosed. Although distorted body image is the main reason for consulting a specialist, the patient presented because he was unable to find a proper shoe. The patient had no familial history of brachydactyly, trauma, or a genetic disorder. In this extremely rare case, the decision was made to perform shortening of the normal foot ray with a double osteotomy to the metatarsal and proximal phalanx. At the end of the follow-up period, the patient was walking pain-free and had no limitation in shoe choice.
Abstract
Background: Ideal suture technique and type in tendon repair are remain unclear. This biomechanical study aimed to assess the biomechanical characteristics of three techniques, modified Kessler (mKE), modified Krackow (mKR), and modified tension Bunnell (mtBU), in sheep Achilles’ tendon tear repair using three suture types, polypropylene, polyester, and ultra-high molecular weight polyethylene (UHMWPE) sutures, which are also compared.
Methods: Sixty-three Achilles’ tendons harvested from sheep were transversely hacked as a replacement for rupture in a standardized measure and repaired using mKE, mKR, and mtBU techniques with No. 2 polypropylene, polyester, and UHMWPE sutures. Biomechanical parameters, such as Young’s modulus, ultimate strength, and strength to the 5-mm gap were recorded for statistical analysis.
Results: The mtBU technique with UHMWPE use resulted in increased ultimate strength, strenght to 5-mm gap, Young’s modulus, and quantity of specimens with low clinical failure modes compared to other techniques with other suture materials. Furthermore, mtBU has the lowest thickness at the repair side of the tendons. This approach showed tendon failure during maximal traction testing, whereas the mKE and mKR had polyethylene and polyester suture failures.
Conclusions: The UHMWPE suture was significantly superior to the other sutures in each suture techniques in terms of strength and durability. The mtBU technique using UHMWPE suture showed better biomechanical results, implying that this repair might be more appropriate to obtain early mobilization after tendon ruptures.
