Plexus Lumbosacralis DUO

Transition concept for the lumbosacral field, where lumbar and sacral territories meet across the pelvic rim.

Formulated for the broad transition band in which the lower lumbar segments hand over to the sacral plexus, following the surface projection across the iliac crest and the posterior pelvic rim.

Purpose

Why this formulation exists

Plexus Lumbosacralis DUO is documented as a cutaneous topical composition for the lumbar application field. This summary is maintained by the documentation team and updated with each revision of the record.

Why this record exists

Supports a structured routine across a field that is otherwise difficult to define, by anchoring the application to two reproducible bony landmarks.

Neurocutaneous region it was designed for

Lumbosacral neurocutaneous zone · Sacral neurocutaneous zone

Anatomical interface it addresses

Thoracolumbar junction and lumbar plexus projection field, extending toward the anterior thigh.

Clinical philosophy

The lumbosacral trunk carries L4 and L5 fibres into the sacral plexus. Its surface correlate is a diagonal band rather than a single dermatome, which is why the application field is described by landmarks instead of segments alone.

  • The field spans two plexus territories; document which landmark line was used so sessions remain comparable.
  • Cutaneous topical composition; the application field is defined by the treating professional.

Protocol

Application protocol

  1. Application

    Single-phase application

    1–2 applications per day

    Defined observation period

    One thin layer is applied across the documented field, following the same sequence at every session.

    Iliac crest linePosterior superior iliac spineUpper gluteal quadrantSacroiliac projection
  2. Maintenance

    Continued routine

    1–3 sessions per week

    Ongoing, reviewed periodically

    The routine is continued at a reduced cadence and reviewed with the practitioner at agreed intervals. Observations stay in the professional log so successive periods remain comparable.

Composition

Formulation architecture

The composition is documented as a map rather than a list. Every constituent is recorded with the function it carries, the reason it is present in this field, how it relates to the rest of the composition and the cutaneous topical formulation category it belongs to.

Carrier systemHumectantEmollientConditioning agentAntioxidant stabiliser
  1. 01Aqua base

    Aqua

    Carrier system

    Functional role
    Carrier phase
    Formulation purpose
    Sets the water phase that determines spreadability across a defined surface field.
    Interaction within the composition
    Holds the humectant fraction in solution and carries the emulsified lipid phase evenly over the zone.
  2. 02Glycerin

    Glycerin

    Humectant

    Functional role
    Moisture binding
    Formulation purpose
    Keeps the applied layer supple so the same field can be worked repeatedly without dryness on the skin surface.
    Interaction within the composition
    Balances the emollient fraction: the humectant governs the water phase, the emollient the lipid phase.
  3. 03Shea butter

    Butyrospermum parkii butter

    Emollient

    Functional role
    Skin-feel and occlusive body
    Formulation purpose
    Gives the texture enough body to stay on the applied zone rather than running along the hairline.
    Interaction within the composition
    Carries the lipid-soluble antioxidant fraction and slows the evaporation of the water phase.
  4. 04Panthenol

    Panthenol

    Conditioning agent

    Functional role
    Surface conditioning
    Formulation purpose
    Documented as a conditioning constituent of the cutaneous topical base; contributes to a smooth, non-tacky finish.
    Interaction within the composition
    Water-soluble; works alongside glycerin in the same phase without altering the emulsion.
  5. 05Tocopherol

    Tocopherol

    Antioxidant stabiliser

    Functional role
    Formulation stability
    Formulation purpose
    Protects the lipid fraction over the shelf life of the record so successive batches stay comparable.
    Interaction within the composition
    Dissolved in the shea fraction; stabilises the constituents it is dispersed in rather than acting on the skin.

Reading the map

Constituents are grouped by formulation category: a carrier system that governs spread, a water phase that governs feel, a lipid phase that governs stay-time, and stabilising constituents that keep successive batches comparable. Interactions describe the composition only; no physiological effect is asserted.

Cutaneous topical formulation rationale

The formulation is built for reproducible application on the documented zones: a texture that spreads thinly, a controlled sensory profile and a composition suitable for repeated professional use.
