Outcomes After Flexor Tendon Repair Combined With the Application of Human Amniotic Membrane Allograft

ABSTRACTStronger flexor tendon repairs facilitate early active motion therapy protocols. Core sutures using looped suture material provide 1 ½ to twice the strength of Kessler′s technique (with four strand and six strand Tsuge technique respectively). The technique is well-described and uses preformed looped sutures (supramid). This is not available in many countries and we describe a technique whereby looped sutures can be introduced in flexor tendon repair by the use of 23 G hypodermic needle and conventional 4.0 or 5.0 sutures. This is an alternative when the custom made preformed sutures are not available. This can be practiced in zone 3 to zone 5 repairs. Technical difficulties limit its use in zone 2 repairs.

No Man's Land

The methods used by Buck-Gramcko, Kleinert and Tsuge in evaluating the functional results of flexor tendon repair were each applied to assess the functional outcome in sixty-seven fingers where both tendons had been severed in “no man's land”. The method of Buck-Gramcko gave the highest rating, and the three methods showed evident differences in the results of evaluation after surgery. The study suggests a need for one standard method of measurement and recording, if a comparison of results after flexor tendon repair is to be of value. We found that the method of Buck-Gramcko incorporated the most essential features in the functional evaluation.

Repair Techniques

Multiple-strand repair techniques are commonly used to repair cut flexor tendons to achieve initial biomechanical strength. Looped sutures achieve multiple strands with fewer passes and less technical complexity. Their biomechanical performance in comparison with an equivalent repair using a single-stranded suture is uncertain. This study examined the mechanical properties of double-stranded loops of 3-0 and 4-0 braided polyester (Ticron) and polypropylene monofilament (Prolene). Double loops were generally less than twice the strength of a single loop. Ticron and Prolene had the same strengths, but Ticron was stiffer. The 4-0 double loops had significantly higher stiffness than 3-0 single loops. Increasing the size of sutures had a larger relative effect on strength than using a double-stranded suture. However, a double-strand loop had a larger effect on increasing stiffness than using a single suture of a larger equivalent size. Looped suture repairs should be compared with standard techniques using a thicker single suture.
