Why this expert

A declared special interest, not an incidental one

The DRUJ is among the areas Professor Warwick is known for

The distal radioulnar joint is one of Professor Warwick's stated special interests and one of the areas in which he publishes. He is first author of Indications and early to mid-term results of ulnar head replacement in the Annals of the Royal College of Surgeons of England, and first author of published correspondence on the Sauvé-Kapandji and Darrach procedures for DRUJ dysfunction following Colles' fracture.

He is also a co-author of the 2026 systematic review of prosthetic arthroplasty of the distal radioulnar joint in the Journal of Hand Surgery (European Volume), and contributed to the NICE review of total DRUJ replacement.

Ulnar-sided wrist pain is among the harder areas to opine on credibly, because presentation is variable and imaging is often equivocal. An opinion from someone who operates on these problems weekly carries weight a general orthopaedic opinion does not.

Scope

What the report can address

Three questions are addressed in every report: whether the treatment chosen fell within the range a reasonable hand surgeon would have offered, whether a complication reflects a recognised risk or a departure from acceptable practice, and what is attributable to the natural history of the condition rather than to the treatment given. Beyond those, the report addresses the issues pleaded, and states a range of opinion where one genuinely exists.

Clinical negligence

Whether ulnar-sided wrist pathology was reasonably identified and investigated, or whether persistent symptoms were attributed to soft tissue injury without adequate assessment.

Whether the procedure selected, whether Darrach, Sauvé-Kapandji, ulnar head replacement or soft tissue reconstruction, fell within the range a reasonable surgeon would adopt.

Causation

Whether DRUJ instability or degeneration is attributable to the index injury, to a malunited distal radius fracture, or to pre-existing change.

Where the literature does not support a confident conclusion either way, the report says so plainly rather than overstating the position.

Condition, prognosis and quantum

Forearm rotation, grip strength, instability and pain on loading, and the effect on work and daily activities.

The likelihood of further surgery, the durability of any prosthesis, and reasonable costings for future treatment.
