Publication Metadata only Elbow joint proprioceptive sense in total arm-type brachial plexus injured patients after neurotization: A preliminary study(2014-01-01) Therdsak Homsreprasert; Roongsak Limthongthang; Torpon Vathana; Saichol Wongtrakul; Panupan Songcharoen; Mahidol Universityof proprioceptive sensation in brachial plexus injured patients after neurotization. Objective: To study elbow joint position sense or proprioceptive sense in total arm-type brachial plexus injured patients after neurotization. Material and Method: The present study...-type brachial plexus injured patients after neurotization, the latter seven of whom experienced recovery of motor power of biceps to at least MRC III. All patients were examined using the CONTREX dynamometer to assess elbow joint position sensePublication Metadata only End-to-side neurorrhaphy to restore elbow flexion in brachial plexus injury(2016-11-01) Roongsak Limthongthang; Torpon Vathana; Saichol Wongtrakul; Panupan Songcharoen; Mahidol University© 2016, Medical Association of Thailand. All rights reserved. Background: End-to-side (ETS) neurorrhaphy is a controversial technique that is used for nerve transfer to achieve functional recovery. The advantage of this technique is the safety of donor nerve function. In this study, patients with extended upper-arm brachial plexus injury and significant hand weakness that did not meet the clinical criteria for end-to-end nerve transfer (Oberlin transfer) were treated by ETS neurorrhaphy to achieve biceps muscle reinnervation. Objective: To evaluate the outcome of ETS for biceps muscle reinnervation in brachial plexus injury patients. Material and Method: Thirteen patients with complete upper-arm and incomplete lower-arm brachial plexus injuries were treated by ETS of the motor branch of the biceps muscle to the ulnar or median nerves using the epineurial window technique. Results: Motor recovery was observed in nine of 13 patients. Good results were achieved in six patients who attained biceps motor power ≥ M3. No additional neurological deficits of the ulnar or median nerves were identified after the surgery. Conclusion: End-to-side neurorrhaphy is a viable treatment option for restoration of biceps muscle function if conventional end-to-end nerve transfer cannot be performed.Publication Metadata only Adult brachial plexus injury.

Lee Osterman; Mahidol University; Thomas Jefferson University Hospitalrecovery and surgery may be needed. Detailed preoperative evaluation is recommended for localization of the lesions. The treatment of upper arm type injury comprises restoration of elbow flexion and shoulder control. Good functional results may be achieved... after multiple nerve transfers. The treatment of total arm type includes hand function reconstruction, in addition to shoulder and elbow treatment. Current options for hand function reconstruction include functioning free muscle transfers and nervePublication Metadata only Management of brachial plexus injury in adults(2008-01-01) Panupan Songcharoen; Mahidol Universityavulsion. In general, the results regarding restoration of shoulder and elbow function are good but reinnervation of the forearm muscles is less than safisfactory in respect to restoration of hand function.

Spinner; Mahidol University; Mayo ClinicA strategy that uses the selective combination of neurotizations can yield a moderate degree of shoulder and elbow control. Even though some wrist and finger movement can occasionally be achieved by the current methods of neurotization, the results
