Recovery of upper extremity function following endoscopically assisted contralateral C7 transfer for obstetrical brachial plexus injury.
Transfer of the contralateral C7 nerve for reconstruction of the brachial plexus in infants with obstetrical brachial plexus injury has rarely been reported. We developed a new endoscopy-assisted technique via the prevertebral (retroesophageal) route for the transfer of the contralateral C7 nerve in reconstruction of the brachial plexus. The reconstruction was performed in 20 infants (14 boys and six girls). Motor recovery was assessed using the Gilbert and Raimondi scales. The Narakas Sensory Grading System was used to evaluate hand sensation. The mean follow-up period was 45 months (SD 18.2). Of the 20 children, nine had contralateral C7 transfer to lower nerve roots, two had transfer to upper nerve roots and nine had transfer to both upper and lower roots. The postoperative shoulder and elbow functions were good or satisfactory according to the Gilbert classification in all children whose preoperative scores were poor. All patients with lower roots reconstruction (9) had satisfactory hand function. A total of 15 children had a Narakas score of S3. Our technique enables safe contralateral C7 transfer to the avulsed roots in severe obstetrical brachial plexus injury infants with a satisfactory functional recovery. ⋯ Level IV.

Distal transfers as a primary treatment in obstetric brachial plexus palsy: a series of 20 cases.
The purpose of this study was to examine the results of spinal accessory nerve to suprascapular nerve (with or without axillary nerve neurotization) and an Oberlin transfer as primary treatment in children with Narakas type I obstetric brachial plexus injuries, when parents refused to consent to conventional nerve trunk-/root-level reconstruction. A total of 20 children with poor shoulder abduction and no biceps antigravity function but with good hand function were treated with spinal accessory nerve to suprascapular nerve and an Oberlin transfer at a mean age of 5.8 months (SD 3.27; range 3-12.) All the patients were evaluated at a mean of 2.8 years (SD 0.8; range 1.5 to 3.8) post-operatively. Three patients were lost to follow-up. Of the remainder, 11 had grade 4+ power of elbow flexion and six patients had grade 4 power at 1 year follow-up; all had 4+ power of elbow flexion at final follow-up. At final follow-up the Mallet score was a mean of 15; (SD 4.22, range 9 to 20). Primary distal nerve transfers can give good outcomes in patients with obstetric brachial plexus injuries and may be an alternative to surgery on the nerve trunks ⋯ IV.

Controlled Clinical TrialInter- and intra-tester reliability of sensibility testing in digital nerve repair.
The aim of this study was to investigate the inter- and intra-tester reliability of the static two-point discrimination and Semmes-Weinstein monofilament tests in digital nerve repair. A total of 100 digital nerves from 67 patients were included into the study. ⋯ These tests should not be used alone in the quantitative monitoring of sensory recovery, but should be interpreted with the clinical findings. Level 3 non-randomized controlled study.

Meta AnalysisIs intramedullary nailing better than the use of volar locking plates for fractures of the distal radius? A meta-analysis of randomized controlled trials.
We conducted a meta-analysis of randomized controlled trials that compared the use of intramedullary nails and volar locking plates in distal radial fractures. PubMed, EMBASE and the Cochrane Collaboration Central database were used to find randomized controlled trials that met the eligibility criteria. Two reviewers screened the studies, extracted the data, evaluated the methodological quality and analysed the data with RevMan 5.1 software. No statistically significant differences were detected in the disability of the arm, shoulder and hand and the Gartland and Werley scores, radiographic parameters, wrist range of motion, grip strength, total complication rate and incidence of tendon rupture between the two groups. However, carpal tunnel syndrome occurred less often after intramedullary nailing. The two fixation methods achieved equal clinical, functional and radiological outcomes for primary fixation of the indicated types of distal radial fractures. ⋯ Therapeutic/LevelI.

Comparative StudyMeasurements of surgeons' exposure to ionizing radiation dose: comparison of conventional and mini C-arm fluoroscopy.
This study was performed to measure the equivalent scattered radiation dose delivered to susceptible organs while simulating orthopaedic surgery using conventional and mini C-arm fluoroscopy. In addition, shielding effects on the thyroid, thymus, and gonad, and the direct exposure delivered to the patient's hands were also compared. A conventional and mini C-arms were installed in an operating room, and a hand and an operator phantom were used to simulate a patient's hand and a surgeon. ⋯ The direct radiation dose to the hand phantom measured from the mini C-arm was significantly lower than that measured from the conventional C-arm. The results show that the equivalent scattered radiation dose to the surgeon's susceptible organs and the direct radiation dose to a patient's hand can be decreased significantly by using a mini C-arm rather than a conventional C-arm. However, protective lead garments, such as a thyroid shield and apron, should be applied to minimize radiation exposure to susceptible organs, even during use of mini C-arm fluoroscopy.
