Case Report: Bionic Reconstruction in an Adult With Obstetric Brachial Plexus Injury

Introduction: Many adults who had a severe Narakas IV obstetric brachial plexus injury (OBPI) suffer from extensive impairments in daily living due to limited hand-arm function. The dramatic loss of axonal support at this very early age of development often render the entire extremity a biologic wasteland and reconstructive methods and therapies often fail to recover any functional hand use. In this scenario bionic reconstruction, including an elective amputation and a subsequent prosthetic fitting, may enable functional improvement in adults suffering from the consequences of such severe brachial plexus injuries. We here describe our experience in treating such patients and lay out the surgical rational and rehabilitation protocol exemplified in one patient.Case Presentation/Methods: A 27-year-old adult with a unilateral OBPI contacted our center. He presented with globally diminished function of the affected upper extremity with minimal hand activity, resulting in an inability to perform various tasks of daily living. No biological reconstructive efforts were available to restore meaningful hand function. An interdisciplinary evaluation, including a psychosocial assessment, was used to assess eligibility for bionic reconstruction. Before the amputation and after the prosthetic fitting functional assessments and self-reported questionnaires were performed.Results: One month after the amputation and de-rotation osteotomy of the humerus the patient was fitted with a myoelectric prosthesis. At the 1.5 year-follow-up assessment, the patient presented with a distinct improvement of function: the ARAT improved from 12 to 20 points, SHAP score improved from 8 to 29, and the DASH value improved from 50 to 11.7. The average wearing times of the prosthesis were 5 to 6 h per day (on 4–5 days a week).Discussion: The options for adults suffering from the consequences of severe OBPIs to improve function are limited. In selected patients in whom the neurological deficit is so severe that biologic hand function is unsatisfactory, an elective amputation and subsequent restoration of the hand with mechatronic means may be an option. The follow-up results indicate that this concept can indeed lead to solid hand function and independence in daily activities after amputation, subsequent prosthetic fitting, and rehabilitation.

The Effects of Virtual Reality on Upper Extremity in Patients with Obstetric Brachial Plexus Injury

The present study aimed to examine the effects of playing Nintendo Wii games on upper extremity functions compared with conventional physiotherapy, in children with obstetric brachial plexus injury (OBPI). Twenty-two patients with brachial plexus injuries were enrolled. The patients were divided into two groups by simple randomization. The control group (conventional physiotherapy group [CTG]: n = 11) received conventional physiotherapy for 6 weeks (40 minutes per day, for 4 days per week). The study group, called Nintendo Wii group (NWG; n = 11), received conventional physiotherapy as well as tennis, baseball, and boxing games with Nintendo Wii on days when there was no physical therapy. The upper extremity range of motion (ROM) was evaluated using a digital goniometer, motor function was assessed using the Active Movement Scale (AMS), and shoulder functions were assessed with the Mallet Scoring System (MSS). Virtual reality treatment had a positive effect on shoulder flexion, forearm pronation, wrist flexion, ROM, and functionality (p < 0.05). There was a significant improvement in shoulder abduction and shoulder external rotation in the CTG (p < 0.05). There was no significant difference in the MSS values of either groups (p > 0.05). As per the AMS, in the NWG, the shoulder internal rotation increased significantly (p < 0.05). Nintendo Wii treatment used in addition to conventional physiotherapy may be effective in increasing upper extremity functions in children with OBPI. Clinical Trials Number NCT04605601.

Evidence that nerve surgery improves functional outcome for obstetric brachial plexus injury

The majority of children with obstetric brachial plexus injury show some degree of spontaneous recovery. This review explores the available evidence for the use surgical brachial plexus repair to improve outcome. So far, no randomized trial has been performed to evaluate the usefulness of nerve repair. The evidence level of studies comparing surgical treatment with non-surgical treatment is Level IV at best. The studies on natural history that are used for comparison with surgical series are also, unfortunately, of too low quality. Among experts, however, the general agreement is that nerve reconstruction is indicated when spontaneous recovery is absent or severely delayed at specific time points. A major obstacle in comparing or pooling obstetric brachial plexus injury patient series, either surgical or non-surgical, is the use of many different outcome measures. A requirement for multicentre studies is consensus on how to assess and report outcome, both concerning motor performance and functional evaluation.

Effect of augmented biofeedback for improvement of range of motion and upper extremity functionality in obstetric brachial plexus injury: a randomised control trial

Background/Aims The loss of mobility and functional activities of the upper limb are the main longstanding complications of obstetric brachial plexus injury. The aim of this study was to investigate the effect of the augmented biofeedback system in conjunction with traditional physical therapy on the range of motion and functional activities in children with obstetric brachial plexus injury. Methods A total of 45 children aged from 6 to 10 years with obstetric brachial plexus injury were assigned into two groups. The control group received a traditional physical therapy programme, and the study group received the same programme with augmented biofeedback for 6 weeks. The main outcome parameters were the upper limb active range of motion, Mallet scale and Active Movement scale. Results The children in the study group showed greater significant improvement in all measured parameters compared with those in the control group. Conclusions Adding augmented biofeedback to the physical therapy programme provided greater improvement in upper limb mobility and functional activities for children with obstetric brachial plexus injury children.
