background lesions in peripheral nerves are highly prevalent in the upper extremity. the present study compares different tendon transfer surgeries in patients with radial nerve palsy. methods fifty patients with radial nerve palsy were randomly selected among patients who referred to tehran 15th khordad hospital during 2006-2011. they were divided into two groups of 17 and 33 subjects. single ...

results in 41 of 186 (22%) hands, the palmaris longus tendon was absent and absence of the fifth flexor digitorum tendon was noted in eight (4.30 %). the median surface area in the hands without palmaris longus was meaningfully lower than the hands with it (p = 0.025), while the difference in the median surface area was not statistically significant with regard to presence of the fifth flexor d...

Closed tenotomy was used to treat triggering of the fingers and thumb in 54 patients. In 56 digits the method was successful; in seven it was a simple matter to proceed to open tenotomy. With experience, the closed procedure can be completed within minutes without risk of damaging the digital nerves.

A new type of in vivo tissue engineering system for tendon repair in situ after cut or crush of a flexor tendon is described. The system is based on the topographical reaction, alignment, migration and perhaps proliferation of tendon cells on micrometrically grooved substrates made in a biodegradable polymer. Macrophage trapping in the structure may also help to prevent inflammation. Tendon dam...

Regaining satisfactory digital function after flexor tendon laceration and repair within the digit has long been one of the most difficult problems in hand surgery. Until the 1960s it was universally recommended that tendons divided in the digit (then referred to as “no man’s land”) should not be repaired. Bunnell taught that “it is better to remove the tendons entirely from the finger and graf...
