Proximally based sural adipose-cutaneous/scar flap in elimination of ulcerous scar soft-tissue defect over the achilles tendon and posterior heel region: a new approach

Repair of Small-Size Wound With Achilles Tendon Exposure With Proximal Pedicled Cutaneous Neurovascular Flap

OBJECTIVE

To investigate the clinical outcomes associated with repairing of small-sized wounds of Achilles tendon exposure with proximal pedicled cutaneous neurovascular flap in the dorsolateral foot.

METHODS

After thorough debridement, 16 cases with small-sized wounds of Achilles tendon exposure were repaired by proximal pedicled cutaneous neurovascular flap of the dorsolateral foot, and their clinical outcomes were observed.

RESULTS

All the flaps in the 16 cases survived completely, excluding the marginal part necrosis in 1 case, and all the wounds were healed. The 2-point discrimination of the flaps was 14.53 ± 1.55 mm (range, 12-17 mm) in patients without sural nerve injury after 3 to 18 months follow-up. No discomfort was felt in wearing normal shoes by all the 16 patients.

CONCLUSIONS

It is reasonable to repair the small-sized wounds of Achilles tendon exposure with proximal pedicled cutaneous neurovascular flap of dorsolateral foot due to its effective repair of the wound, relatively uncomplicated surgery, and had satisfactory healing recovery.

Long-Term Clinical and Functional Outcomes of Distally Based Sural Artery Flap: A Retrospective Case Series

Background

Reconstruction of soft tissue defects around the lower leg, foot and ankle is a challenge for orthopedic surgeons. These defects commonly occur as a result of trauma, infection and tumor excision. Sural artery neurovascular island flap is a relatively thin, pliable and insensate flap with minimum donor-site morbidity and acceptable aesthetic outcome.

Methods

A retrospective analysis of a case series was conducted, all operated by a single surgeon over a period of 25 years from July 1996 to February 2020. Data were collected through a structured proforma; the variables included were as follows: demographic data, mechanism of injury, defect site and size, size of flap, hospital stay, complications, outcome of flap and functional status of limb. Data analysis was performed by using SPSS version 25.0.

Results

We included 89 patients out of 106, with 92 distally based sural artery flaps. The flap coverage was divided in two groups: group I for leg (n=41) and group II for foot (n=51). The mean flap dimension in leg was 9.98 ± 2.2 cm and 12.15 ± 3 cm in foot. Postoperatively functional outcomes were assessed using a self-designed tool and graded as excellent in 79 cases (leg=38; foot=41), good in 10 cases (leg=2; foot=8), fair in 3 cases (leg=1; foot=2) and poor in zero cases. All flaps survived uneventfully.

Conclusion

The reverse sural artery flap is versatile and reliable, and can be performed easily with good knowledge and using a microsurgical technique. It is useful for the reconstruction of soft tissue defects around the lower third of the leg, dorsum of the foot, malleoli and hind foot. The functional range of motion of the ankle is not compromised because of the flap's supple and pliable nature. The reverse sural artery flap is ideal for the coverage of the foot, ankle and lower one third of the leg. This flap is insensate and not suitable for the weight-bearing area of the heel.

Soft-tissue defects of the Achilles tendon region: Management and reconstructive ladder. Review of the literature

INTRODUCTION

Defects of the Achilles tendon region represent a challenge for reconstructive surgeons. Several options are available but there is still no reconstructive ladder for this specific and tricky area. An up-to-date reconstructive ladder according to local and general conditions is proposed based on our multicentre experience and an extensive review of the English literature on PubMed.

MATERIALS AND METHODS

An extensive review of the English literature was performed on PubMed using the following key-words: "Achilles region", "heel", "soft-tissue reconstruction", "flaps", "grafts" and "dermal substitutes".

RESULTS

A total of 69 complete papers were selected, covering the last thirty years' literature. Although most of the studies were based on limited case-series, local and general conditions were always reported. A comprehensive reconstructive ladder of all the available reconstructive techniques for the Achilles region has been created based on our personal multicentre experience and the results of the literature review.

CONCLUSIONS

The reconstructive ladder is a concept that is still a mainstay in plastic surgery and guides decisions in the repair strategy for soft tissue defects. The optimal solution, according to the experience of the surgeon and the wishes of the patient, is the one that implies less sacrifice of the donor site. Perforator flaps should be the first-line option for small-to-moderate defects; the distally-based sural flap is the most reported for moderate-to-large defects of the Achilles region, and free flaps should be reserved mainly for complex and wide reconstructions.

Flap decisions and options in soft tissue coverage of the lower limb

THE LOWER EXTREMITIES OF THE HUMAN BODY ARE MORE COMMONLY KNOWN AS THE HUMAN LEGS, INCORPORATING: the foot, the lower or anatomical leg, the thigh and the hip or gluteal region. The human lower limb plays a simpler role than that of the upper limb. Whereas the arm allows interaction of the surrounding environment, the legs' primary goals are support and to allow upright ambulation. Essentially, this means that reconstruction of the leg is less complex than that required in restoring functionality of the upper limb. In terms of reconstruction, the primary goals are based on the preservation of life and limb, and the restoration of form and function. This paper aims to review current and past thoughts on reconstruction of the lower limb, discussing in particular the options in terms of soft tissue coverage. This paper does not aim to review the emergency management of open fractures, or the therapy alternatives to chronic wounds or malignancies of the lower limb, but purely assess the requirements that should be reviewed on reconstructing a defect of the lower limb. A summary of flap options are considered, with literature support, in regard to donor and recipient region, particularly as flap coverage is regarded as the cornerstone of soft tissue coverage of the lower limb.
