What documentation and arguments should I prepare for my CPS expert appointment to settle a negligence claim regarding a 7–8 month cast that resulted in malunion and chronic wrist dysfunction, admitted by the hospital five years after the injury?

Preparing for Your CPS Expert Appointment: Documentation and Strategy

You should compile comprehensive medical records documenting the prolonged immobilization, radiographic evidence of malunion, functional deficits, and the hospital's admission of negligence to establish causation between the 7-8 month casting period and your chronic wrist dysfunction.

Essential Documentation to Gather

Medical Records

• Complete radiographic series: Initial injury films, serial follow-up X-rays during the 7-8 month casting period, and current imaging showing malunion. The ACR guidelines specifically identify malunion evaluation as requiring assessment of alignment parameters 1.

• Hospital admission of negligence: The written acknowledgment from 5 years post-injury is your most critical document. This establishes liability directly.

• Treatment timeline: Detailed records showing the duration of immobilization, any documented concerns about alignment during follow-up, and whether secondary displacement occurred that should have prompted surgical intervention 2.

Current Functional Assessment

Obtain recent objective measurements:

• MRI without contrast to document current soft tissue pathology including tendinopathy, ligament injury, and cartilage damage 1. This imaging modality changed clinical management in 69.5% of hand/wrist cases and is particularly valuable for documenting chronic sequelae.

• Grip strength measurements compared to your uninjured side

• Range of motion documentation (flexion, extension, radial/ulnar deviation, pronation/supination)

• Patient-reported outcome measures: QuickDASH scores and visual analog scales for pain and function are standard metrics used in litigation 3

Key Arguments to Present

Negligence Framework

The case parallels documented malpractice patterns 2. A nearly identical case involved a 74-year-old with distal radius fracture treated conservatively for 9 months (7 months physiotherapy) where arbitration boards found malpractice based on:

1. Failure to recognize radiological instability criteria requiring surgical intervention
2. Continuation of conservative treatment despite secondary displacement on follow-up radiographs
3. Resulting severe deformity causing functional impairment

Specific Negligence Elements

Duration of immobilization: 7-8 months of casting is extraordinarily prolonged. Standard treatment guidelines suggest surgical fixation for fractures with post-reduction radial shortening >3mm, dorsal tilt >10°, or intra-articular displacement 4. If these criteria were met during your follow-up period, continued casting constituted treatment error.

Common litigation patterns: Analysis of 430 hand surgery malpractice claims identified distal radius fractures as the most common diagnosis (21%), with failure to diagnose/treat (34%) and improper procedure/treatment (19%) as leading allegations 5. Your case fits this established pattern.

Causation and Damages

Document specific functional limitations:

• Activities of daily living impairments
• Occupational limitations
• Pain levels (current and trajectory since injury)
• Need for future interventions (corrective osteotomy, salvage procedures)

Long-term prognosis: Malunion following prolonged conservative treatment can lead to permanent deformity, loss of grip strength, and future arthritic deformation 2. Recent evidence shows surgical correction of malunion requires complex interventions with variable outcomes 6, 7.

Critical Pitfalls to Avoid

Do not accept arguments that malunion is clinically insignificant: While some research suggests older, low-activity patients tolerate malunion 3, this does not excuse negligent treatment that caused the malunion. The hospital's admission of negligence already establishes this point.

Distinguish your case from acceptable outcomes: The 7-8 month immobilization period is the key differentiator. Standard treatment involves weeks, not months, of casting 4.

Prepare for defense arguments about activity level: If they suggest malunion doesn't affect function, counter with your specific documented functional deficits and the fact that the hospital already admitted negligence.

Settlement Positioning

Quantifiable damages include:

• Past and future medical expenses (including potential corrective surgery)
• Lost wages and diminished earning capacity
• Pain and suffering
• Permanent functional impairment

Leverage the admission of negligence: This eliminates the need to prove liability, shifting focus entirely to damages. The hospital's acknowledgment 5 years later suggests they recognized the treatment fell below standard of care.

Reference comparable settlements: Hand surgery malpractice settlements averaged $551,957, with plaintiff verdicts averaging $832,258 5. Cases involving treatment errors and resulting functional limitations form the basis for these awards.
