1	Radial nerve palsy L C Bainbridge Hand Surgeon Derbyshire Royal Infirmary UK
2	History Sir Robert Jones 1916 PT → ECRL and B FCU → EDC III – V FCR → EIP, EDC II, EPL 1921 PT → ECRL and B FCU → EDC III – V FCR V EIP, EDC II, EPL, EPB and APL Zachary 1946 showed the problems of unstabilised wrist
3	Wrist PT → Wrist Extension is fairly accepted Force 1.2kg adequate and excursion of 5cm greater than ECRL or B However transfer to ECRL → radial deviation ECRB → some deviation √ ECU → Small moment arm Combination √
4	Fingers FCU, FCR, one or more finger flexors FCU strength 2Kg √ Exc 3.3cm (4-5 for ECR) √ FCR even worse FCU important for hand function? Boyes suggested FCR → APL and FDS IV → EPL and EIP, and FDS III → EDC
5	Thumb 2 columns diverging in axes and course Same for EDC and EPL X Scuderi’s technique of rerouting EPL radial to Listers tubercle. ? Loses retroposition Loses active wrist tenodesis
6	Standard set of Transfers PT → ECRB (Rerouted ECRL) FCU → EDC and EIP PL → EPL (rerouted)
7	Incisions
8	Elevating FCU
9	Pronator Teres
10	ECRL and B
11	FCU transfer Split FCU into 2 strips Resect 4-5cm of distal muscle Wrist in 40º of extension and fingers in full extension Resect proximal EDC
12	PL transfer Scuderi suggested bringing EPL radial to Listers tubercle outside dorsal retinaculum Better to reroute through 1^st or 2^nd compartment
13	PT Transfer Wrist in 40º of extension PT in full tension Woven through both ECRB and ECRL just distal to musculotendinous junction
14	Heavy manual worker Maintain FCU Use FDS IV → EDC II-V FCR → EIP and EPL PT → ECRB,L (PL → APL, EPB)
