Summary
The reverse-flow sural fasciocutaneous flap is an effective treatment for complex lower limb lesions, showing an 87.5% success rate. This method offers a viable alternative for wound coverage, with complications linked to patient comorbidities.
Area of Science:
- Plastic Surgery
- Reconstructive Surgery
- Orthopedic Surgery
Background:
- Complex lower limb lesions present significant reconstructive challenges.
- The reverse-flow sural fasciocutaneous flap is a potential reconstructive option.
Purpose of the Study:
- To evaluate the efficacy and outcomes of the reverse-flow sural fasciocutaneous flap for covering distal lower limb lesions.
Main Methods:
- Retrospective analysis of 24 patients undergoing reverse-flow sural fasciocutaneous flap reconstruction.
- Inclusion criteria: traumatic injuries, sports injuries, and tumor resections in the distal third of the lower limb.
Main Results:
- A total of 24 patients (16 male, 8 female; age 6-75) were analyzed.
- Successful flap healing occurred in 87.5% (21/24) of cases.
- Complications, including partial or total flap necrosis, were associated with comorbidities (diabetes, hypertension, smoking) and not the learning curve or lesion characteristics.
Conclusions:
- The reverse-flow sural fasciocutaneous flap demonstrates a high success rate (87.5%) for complex lower limb lesions.
- It is a clinically relevant and effective reconstructive alternative.
- Comorbidity management is crucial for optimizing outcomes.

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

The human body consists of an intricate network of veins responsible for the crucial task of blood drainage from the lower limbs. These veins can be categorized into two main types: deep veins and superficial veins.
Formed by the union of the medial and lateral plantar veins, the posterior tibial vein, rising through the calf muscle, assimilates the fibular vein. The anterior tibial vein, a superior extension of the foot's dorsalis pedis vein, merges with the posterior tibial vein at the...

The human circulatory system, a marvel of biological engineering, is a complex network of vessels that transport blood throughout the body. Among these, the veins responsible for carrying blood from the upper limbs are divided into two categories: deep and superficial.
The deep venous system is primarily composed of the ulnar and radial veins. The ulnar vein, which drains the fingers through the superficial palmar venous arches, and the radial vein, which serves the palms via the deep palmar...

The subclavian artery transitions into the axillary artery as it exits the chest and enters the axillary region. This artery is critical for supplying blood to the shoulder area, including the head of the humerus, through the humeral circumflex arteries. As the vessel continues into the upper arm or brachium, it becomes the brachial artery. This artery plays a key role in vascularizing the brachial region and bifurcates at the elbow into several branches. These branches include the deep...

01:10Reconstruction of Signal using Interpolation

Signal processing techniques are essential for accurately converting continuous signals to digital formats and vice versa. When a continuous signal is sampled with a period T, the resulting sampled signal exhibits replicas of the original spectrum in the frequency domain, spaced at intervals equal to the sampling frequency. To handle this sampled signal, a zero-order hold method can be applied, which creates a piecewise constant signal by retaining each sample's value until the next...

01:15Bones of the Upper Limb: Ulna
4.2K
The ulna and radius are parallel bones of the antebrachium or the forearm. The ulna lies medially and consists of a bony tip called the olecranon process at its proximal end. This hook-like projection articulates with the olecranon fossa of the humerus and forms the "hinged" ulnohumeral part of the elbow joint. This joint facilitates forearm extension and flexion while preventing its hyperextension. Similarly, the coronoid process, another bony projection on the proximal/anterior side...
