17.3 Chiropractic Adjustive Technique: Lumbar, Pelvic, Costal, and Extremity

17.3 Chiropractic Adjustive Technique: Lumbar, Pelvic, Costal, and Extremity

Quick Answer: Lumbar and pelvic work dominates many clinical encounters and a large share of Part II technique items. Master side-posture blocking, understand pelvic listings as setup guides, know when SI and hip pathology mimics lumbar pain, and apply the same contraindication framework to extremity joints.

Lumbar Spine: Setup and Line of Drive

The lumbar spine tolerates HVLA well in healthy patients, but disc, stenosis, and cauda equina risks make screening essential before any thrust.

Side-Posture Lumbar Adjustment

The most tested lumbar setup is side-posture with pelvic and shoulder blocks:

• Patient lies on the side with the superior leg flexed (hip and knee flexed) to open lumbar facets on the side to be adjusted.
• Inferior shoulder rolls forward; doctor's contact hand targets the mammillary process or transverse process of the fixated segment.
• Stabilizing hand (often on patient's ASIS or shoulder) maintains segmental pre-stress.
• Line of drive is typically posterior-anterior with a rotational component matching the restriction (e.g., PS spinous or PL lamina contacts for rotational restrictions).

Pre-stress rotates the patient slightly toward or away from the doctor to engage the target segment before the thrust. Vignettes asking which leg position opens L4–L5 on the right typically involve flexing the superior leg on the left side-lying position to adjust the right lumbar facets.

Prone and Supine Lumbar Alternatives

• Prone push move — Doctor stands beside table, contact on spinous or transverse process, stabilization via thigh or ilium.
• Supine lumbopelvic drop — Table drop piece assists with less manual force; useful for larger patients or when reducing HVLA amplitude.
• Flexion-distraction (Cox) — Slow rhythmic traction-flexion; preferred with disc herniation without progressive neurologic deficit, stenosis, or acute radiculopathy where HVLA is relatively contraindicated.

Lumbar Indications

• Segmental hypomobility with mechanical low back pain
• Sacroiliac dysfunction as part of a lumbopelvic complex (after ruling out inflammatory arthropathy)
• Muscular guarding secondary to facet restriction

Lumbar Contraindications

Absolute:

• Cauda equina syndrome (saddle anesthesia, urinary retention or incontinence, bilateral leg weakness) — emergency referral, no manipulation
• Acute fracture or dislocation
• Progressive neurologic deficit from disc herniation or stenosis
• Spinal infection or malignancy
• Abdominal aortic aneurysm suspected (pulsatile mass, at-risk profile)

Relative:

• Large disc herniation with radiculopathy — prefer flexion-distraction, mobilization, or referral; avoid rotational HVLA toward the herniation
• Severe central stenosis — avoid extension-heavy thrusts
• Osteoporosis — reduce force, consider drop or instrument methods
• Pregnancy — modify positioning and force; Webster and gentle pelvic balancing may be appropriate after training

Pelvic and Sacral Technique

Pelvic analysis uses landmark palpation (ASIS, PSIS, iliac crest, sacral base, apex) and motion tests (Gillet/Stork, seated flexion, prone leg check in some systems). Listings describe ilium position relative to the sacrum:

Sacral listings (e.g., base posterior, apex deviated) guide sacral adjustment contacts. Part II rarely requires memorizing every Gonstead listing code, but you must know that listings inform setup direction, not replace clinical reasoning.

Sacroiliac inflammation from ankylosing spondylitis or sepsis is not a simple fixation—manipulation may be contraindicated. Hip osteoarthritis and referred pain must be differentiated from primary SI dysfunction.

Costal (Rib) Technique

Rib restrictions present as sharp pleuritic-type pain, pain with deep breathing, or interscapular aching. Palpate costovertebral and costotransverse angles for tenderness and asymmetry.

Setup Principles

• Prone — Doctor contacts rib angle with stabilizing hand on adjacent spinous process; thrust direction respects rib bucket-handle vs. pump-handle mechanics.
• Supine — Patient arm positioned overhead or crossed to pre-stress the rib; contact on shaft or angle with stabilization at the sternum or adjacent rib.
• Seated — Useful for upper ribs; scapular stabilization limits compensatory thoracic motion.

Costal Contraindications

Absolute: Acute rib fracture, suspected malignancy, unresolved cardiac or pulmonary pathology causing chest pain.

Relative: Osteoporosis, costochondritis (gentle methods), recent thoracic surgery.

Costal adjusting without clearing cardiac causes of chest pain is a frequent board error—always correlate with history and vital signs when appropriate.

Extremity Adjustive Technique

Extremity manipulation restores joint play in shoulders, elbows, wrists, hips, knees, ankles, and feet. The same framework applies:

1. History and mechanism — Fall on outstretched hand, twisting knee injury, repetitive overuse.
2. Inspection and palpation — Swelling, deformity, warmth.
3. Stress tests and imaging when fracture, dislocation, or ligament rupture is suspected.
4. Setup with traction or compression pre-stress aligned to joint anatomy (e.g., long-axis distraction for ankle mortise, shoulder distraction with scapular stabilization).

Extremity Indications

• Joint fixation without instability
• Adhesive capsulitis phase-appropriate care (avoid aggressive manipulation in acute inflammatory phase)
• Ankle subluxation/fixation post-sprain after fracture ruled out

Extremity Contraindications

Absolute: Fracture, dislocation, septic arthritis, vascular injury, acute complete ligament rupture requiring surgical repair.

Relative: Moderate osteoarthritis (gentle mobilization), hemophilia, anticoagulation, hypermobility syndromes (avoid thrusting into unstable ranges).

Documentation Across Regions

Record each region treated, listing or segment identified, patient position, technique type, and negative screening for red flags when lumbar or pelvic HVLA is performed. If care is deferred due to contraindication, document referral rationale—that answer choice is often correct on Part II case-management items paired with technique vignettes.
