Mid	This article has been rated as Mid-importance on the project's importance scale.

The pathogensis section needs work. There is no mention of the interossei which are IP joint extensors, also supplied by the ulnar nerve.

The role of lumbricals is less clear (refer 12th edition Lasts Anatomy). There role as MCP joint flexors is disputed, and if this were the case, they would likely be inactive during normal MCP joint extension, and therefore not important in maintaining IP joint extension as indicated.

Given that severity of claw hand correlates with lumbrical innervation, it is likely they are actually neutral or MCP joint extensors.

This article needs inclusion of information on interossei and and explanation of the dispute over lumbrical action. — Preceding unsigned comment added by 27.32.159.193 (talk) 22:20, 18 March 2012 (UTC)[reply]

Comment_2:

The interosseous muscles are innervated by the ulnar nerve, but their function is abduction/adduction of the fingers. It is the lumbricals that flexes the MCP joints while keeping the PIP and DIP joints extended.

Causes of Ulnar claw

I was expecting some information in this article about muscular dystrophies, leprosy, Charcot-Marie-Tooth Disease, birth defects, and burns and lesions causing ulnar nerve injury leading to the ulnar claw. But there is no mention of these. --Waqqashanafi (talk) 04:58, 28 January 2016 (UTC)[reply]

Proposed merging

I propose that this page be merged with Ulnar neuropathy. Dr G (talk) 01:40, 13 November 2016 (UTC)[reply]
