Bilayer repair technique with mesh in petit lumbar hernia

Background: Reconstruction of the nose can be difficult due to its complex anatomical features. In 1989, Zitelli described a modified version of the bilobed flap design technique using 45° and 90° angles to improve nasal reconstructions. While the bilobed flap is still frequently referenced in scholarly literature, there seems to be inconsistency in preoperative flap design; these deviations can lead to suboptimal outcomes. The authors aim to illustrate the variability in bilobed flap execution and provide guidelines in preoperative design to improve consistency. Methods: A geometrically-based approach was used to characterize the inconsistency of bilobed repair technique. The pre-operative design images from fifteen scholarly articles were analyzed via a series of measurements and computations to quantify the angle of rotation and dimensions for the primary and secondary lobes. The “Error Quotient” was a calculated ratio that objectively measured the extent to which a bilobed design deviated from Zitelli’s specifications. Results: There was a noticeable variability in the design of both the primary and secondary lobes. Bilobed designs with smaller angles of rotation, particularly of the first lobe, were associated with higher Error Quotients and greater amounts of deviation from Zitelli’s design. Designs with the smallest Error Quotients had a primary lobe rotation that approached 45°. Conclusion: Consistency of application of the bilobed flap should be established to allow for optimal results, particularly with emphasis on design of the primary lobe. This can be accomplished by including a disposable protractor and marker in their sterile kit to measure a 45° rotation.

Organ Systems

Congenital lumbar hernias are uncommonly seen in the pediatric age group, with only about 60 cases reported in the literature. It is usually accompanied by a multitude of congenital anomalies involving different organ systems of the body. For instance, it may involve the ribs, spine, muscles, and the kidneys. Herein, we report a case of congenital lumbar hernia in an 8-month-old boy who underwent an operative repair using a mesh with an uneventful outcome.

Repair Technique

Abstract Background Some unusual rotator cuff (RC) tears are located in more proximal tendinous portions, with substantial remnant tissue attached to the footprint. The two options for surgical repair are sacrificing or preserving the remnant tissue. We introduce a surgical repair technique that preserves as much of the remnant footprint as possible. Surgical technique A double-loaded suture anchor is inserted into the subchondral bone at the medial portion of the RC footprint; the lateral remnant tissue is preserved. Each strand is shuttled and repassed through the medial portion of the tendon in a mattress fashion using a suture hook device. Then, multiple no. 1 PDS sutures are passed through the medial and lateral stumps and left untied. Strands from the suture anchor are first tied in a double mattress fashion. Then, the repair is completed by tying the remaining no. 1 PDS sutures. Conclusions We propose a remnant-preserving RC repair technique for transtendinous RC tears with sufficient tissue remaining within the RC footprint. This technique appears advantageous in terms of re-establishing an environment that promotes tendon healing after repair.

Residual Strains

This paper presents microstructural, hardness and residual strain information for solid-state welds in creep-resistant Cr-Mo steel, made using the new local damage repair technique offered by friction taper stud welding (FTSW). The technique is suitable for making single welds to repair, for example, localised creep damage but can also be extended to deal with planar defects through the use of overlapping welds. Neutron diffraction was used to measure residual strains at a number of positions along a series of 5 overlapping FTS welds.
