- Efficacy and Safety of Oberlin's Procedure in the Treatment of Brachial Plexus Birth Palsy(2012) SIQUEIRA, Mario G.; SOCOLOVSKY, Mariano; HEISE, Carlos Otto; MARTINS, Roberto S.; MASI, Gilda DiBACKGROUND: In brachial plexus injuries, when there are no available roots to use as a source for graft reconstruction, nerve transfers emerge as an elective technique. For this purpose, transfer of an ulnar nerve fascicle to the biceps motor branch (Oberlin's procedure) is often used. Despite the high rate of good to excellent results in adults, this technique is seldom used in children. OBJECTIVE: To evaluate the efficacy and safety of Oberlin's procedure in the surgical treatment of brachial plexus birth palsy. METHODS: Striving to restore elbow flexion, we performed Oberlin's procedure in 17 infants with brachial plexus birth palsy. After follow-up of at least 19 months, primary outcomes were the strength of elbow flexion (modified British Medical Research Council Scale), hand function measured using Al-Qattan's Scale, and comparative x-rays of both hands to detect altered growth. RESULTS: Good to excellent results related to biceps contraction were obtained in 14 patients (82.3%) (3/MRC3, 11/MRC4). The preoperative Al-Qattan Scale score for the hand was maintained at final follow-up. Comparing the treated and normal limb, no difference was observed in hand development by x-ray. CONCLUSION: Oberlin's procedure is an effective and safe option for the surgical treatment of upper brachial plexus birth palsy.
- Surgical treatment of typical peripheral schwannomas: the risk of new postoperative deficits(2013) SIQUEIRA, Mario G.; SOCOLOVSKY, Mariano; MARTINS, Roberto S.; ROBLA-COSTALES, Javier; MASI, Gilda Di; HEISE, Carlos Otto; COSAMALON, Jose GarciaAlthough peripheral schwannomas can be resected without postoperative neurological complications, surgeons must anticipate the possibility that new neurological deficits could develop. In order to evaluate the risk of neurological complications in the surgical treatment of these tumours, we performed a retrospective review of cases involving schwannomas in the extremities, as well as an analysis of the related literature. We reviewed a combined series of 72 schwannomas from the extremities presenting for surgical excision. Meticulous analysis of the files was undertaken, searching for pre-operative findings that could be more frequent in patients with surgical complications. The incidence, severity, and transitory nature of post-operative complications in our series was observed and compared against the literature. Eleven patients (15.2 %) developed new neurological deficits after surgery: sensory disturbance in seven cases, motor weakness in three, and a single wound hematoma. Most of these complications were temporary. Statistical analysis demonstrated a positive relationship between the presence of complications and both patient age under 50 years (p = 0.02) and tumours greater than 3 cm in greatest diameter (p = 0.02). Although relatively infrequent, the potential for novel post-operative deficits after the surgical treatment of peripheral schwannomas does exist and should be included during pre-operative counseling.
