Reconstruction of traumatic lumbar hernias: A case report

BACKROUND

Traumatic lumbar hernias are not common hernias that are encountered by general or plastic surgery teams, however it is important to understand the anatomy of the hernia in order to be able to correct the flank defect. In our patient, the oblique muscles were sheared off the iliac crest periosteum, however the attachments to the ribs and spine were maintained. We were able to successfully place a pre-peritoneal polypropylene mesh which was secured to the musculature, and re-approximate the oblique muscles to the iliac crest using Mitek QUICKANCHOR® sutures. Our case study has been reported in line with the SCARE criteria ([8] Agha et al., 2016).

CASE REPORT

The subject in our case was a 47-year-old gentleman who was involved in a motor vehicle accident, and sustained a traumatic lumbar hernia due to the 3-point seatbelt he was wearing. He was transported via ambulance to our trauma center.

CONCLUSION

Understanding the anatomy and mechanism of injury is the key to reconstructing traumatic lumber hernias. Although not required, mesh reinforcement has significantly reduced the recurrence of all hernias. This is the simplest and most effective way, in our opinion, to return the flank muscles to their native position while providing mesh reinforcement.

Anatomy of medial plantar superficial branch artery perforators: Facilitation of medial plantar superficial branch artery perforator (MPAP) flap harvesting and design for finger pulp reconstruction

BACKGROUND

Medial plantar artery perforator (MPAP) flap was proposed as proper option for finger pulp reconstruction. To provide the previously unavailable vessel information required for this small flap design, this study aimed to gather all necessary anatomy of MPA, MPAP, and their territories of blood supply to apply in clinical MPAP flap reconstruction minimizing perforator injury.

METHODS

Dissection of 30 Thai cadaveric feet for visualizing superficial branch of MPA and its perforators (MPAP) using acrylic dye cannulation were performed. Diameter, length, number of branches, course, distributing areas of these vessels, and also their areas of blood supply were recorded in relation to specified landmarks, eg, C-MTH line; medial calcaneal tuberosity to plantar side of the first metatarsal head and S point; emerging point of superficial branch of MPA from deep fasciae into subcutaneous layer.

RESULTS

Average diameter of MPA at its origin and total length are 1.63 ± 0.3 and 52.8 ± 16.1 mm, respectively. It provides 1-3 perforators, with an average size and length of 0.36 ± 0.11 and 23.2 ± 5.47 mm, respectively. Its distribution is mostly in the posteromedial quadrant within 50 and 30 mm from the midpoint of C-MTH line and the S point, respectively. The estimated perforator flap area is 2.5 cm × 1.5 cm and 4.5 cm × 2.5 cm for single and double perforators, respectively.

CONCLUSIONS

MPAP flap was proved as another ideal option for finger pulp reconstruction. Its limitation is small size of perforators but this can be overcome by using MPA for microsurgical anastomosis instead.
