ASL Roma E Polo Ospedaliero “Villa Betania” Ortopedia e Traumatologia Unità Operativa Chirurgia della Mano Endoscopic carpal tunnel release: fourteen years’ experience with the MENON technique ALFREDO DELL’UOMO M.D. 44° Congresso Nazionale Mano with Japanese Soc. - Milano, 13 ottobre 2006
The major thrust for endoscopic carpal tunnel release (E.C.T.R.), is based on the hypothesis that by selectively transecting T. C. ligament the post-op morbidity can be minimized allowing early return to A.D.L.
F.E.S.S.H. Fourth Congress 1997 E.C.T.R. by Menon single portal technique: clinical & M.R.I evaluation after 160 cases clinical & M.R.I evaluation after 160 cases A.Dell’Uomo, M. Mastantuono B.Congresso Europeo Chirurgia della Mano
M.R.I. measurements of the morphological changes after E.C.T.R. show that the volume increase parallels that open C.T.R. Follow-up show that the volume Increase is long lasting POST PRE
COMPLICATIONS “Sindrome del tunnel carpale” Verduci 2002- Springer Verlag 2006 Prof. P. Bedeschi Persistence of sintoma Recurrence of sintoma Appearance of new sintoma - “skin scar” - “pillar pain” - neurological - vascular - etc
Personal complications 6 Neuroapraxia 3° digital nerve +/- communicating branch ulnar nerve 18 Hypotenar-pillar pain 1 Superficial arch injury 3 Second surgery
Second surgery 1.Incomplete release –neuroapraxia 3° NEUROLYSIS complete relief 2. Incomplete release –abundant scarring NEUROLYSIS no improvement 3. Partial lesion of third digital nerve NEUROLYSIS + DIRECT REPAIR improvement
Complcations of endoscopic and open carpal tunnel release A.K.Palmer – Journal of Hand Surgery (1999) Questionnaries to 1253 members of the American Society for Surgery of the Hand “… report ONLY on complications that they had themselves treated surgically”.
NEUROLOGICAL COMPLICATIONS (5 YEARS) LACERATIONS: MEDIAN NERVE ULNAR NERVE DIGITAL NERVE E.C.T.R. 265 O.C.T.R. 230 “The data support the conclusion that carpal tunnel release, be it endoscopic or open is not a safe and simple procedure”
FINAL CONSIDERATIONS E.C.T.R. with the Menon technique is a reliable alternative treatment to open release Based on the data available, E.C.T.R. has less morbidity in the post-op period, than traditional release Surgeons unfamiliar with arthroscopic techniques may find the procedure tecnically demanding T.C.L. can be adequate and safely sectioned, with high success rate and very few complications If visualization is inadequate the surgeon must be prepared to performe an open release and should not risk injury to neurovascolar structures
