Outcomes of Spinal Accessory Nerve and Intercostal Nerve Transfers for Shoulder Stabilisation and Elbow Extension in Patients with C5,6,7 Root Avulsion Injury.

Background: Upper arm type brachial plexus palsy results in decreased shoulder and elbow function. Reanimation of shoulder and elbow function is beneficial in these patients. The aim of this study is to report the results of restoring the shoulder abduction and elbow extension in patients with C5,6,7 root avulsion injury by simultaneous transfer of the spinal accessory nerve for the supraspinatus muscle combined with the transferring of the sixth and seventh intercostal nerves for the serratus anterior muscle along with the third to fifth intercostal nerves to the triceps muscle. Methods: All patients who underwent the above set of nerve transfers and had at least 2 years of follow-up were included in the study. The outcome measures included the Medical Research Council (MRC) grading of motor strength of shoulder abduction and elbow extension and range of motion of shoulder abduction and shoulder external rotation. Results: The study included 10 patients with an average age of 27. The mean time from injury to surgery was 6 months and the mean follow-up period was 35 months. M4 grade shoulder abduction was restored in five patients, M3 grade in three patients and M2 grade in two. M4 grade elbow extension was achieved in four patients, M3 grade in four patients and M2 grade in two patients. The average arc of shoulder abduction and external rotation was 71° and -21°, respectively. Conclusions: The spinal accessory nerve and the sixth and seventh intercostal nerves transfer to the supraspinatus muscle and serratus anterior muscle with the third to fifth intercostal nerves transfer to the triceps muscle provided satisfactory results for both shoulder abduction and elbow extension in C5,6,7 root avulsion injury. Level of Evidence: Level IV (Therapeutic).

Hybrid Achilles Tendon Repair.

In the treatment of acute Achilles tendon rupture, recent studies demonstrate that conservative treatment with functional rehabilitation provides good results, with nearly identical postoperative rerupture rates when compared with surgical treatment. Surgical treatment is indicated in patients with particular conditions, such as patients who are young active athletes who require early return to play or those who wish to avoid the muscle atrophy associated with conservative methods. If surgery is the selected option for treatment, the postoperative complications of each type of surgery must be considered. In conventional open repair, the most common complication is soft-tissue infection due to the high tension of soft tissue affected from the bowstring of the repaired tendon being kept in the equinus position of the ankle. For percutaneous methods, sural nerve entrapment and injury are the most commonly reported complications. Other methods, including endoscopy, require technical expertise as well as special equipment. Several types of combination approaches have been explored in the literature. We describe a combined open and percutaneous technique to repair the Achilles tendon, called the hybrid Achilles tendon repair. This technique has been developed to provide a simplified and reproducible method of hybrid repair in which the complications of previous methods are avoided and which can be done without special equipment.

Fluoroscopic Technique for Open Reduction and Internal Fixation of Proximal Humeral Fracture Using the Proximal Humeral Locking Plate: Proposal of "Plate" and "Screw" Views.

Proximal humeral fractures are common injuries with increasing incidence, particularly in the aging population. Nondisplaced or minimally displaced fractures can be treated conservatively whereas surgical fixation is usually indicated in the cases of displaced fractures. Various surgical options have been used for treatment of these fractures. Good outcomes have been reported with use of the Proximal Humeral Internal Locking System (PHILOS plate; Synthes, Zuchwil, Switzerland) as the implant of choice. However many complications have been reported, including varus malalignment, excessive retroversion of the articular part of the humerus, penetration of screws, and avascular necrosis of the humeral head. Therefore, we have hypothesized that an inadequate intraoperative fluoroscopic assessment may be an important factor contributing to these complications. We have described a step-by-step intraoperative fluoroscopic setup, including the proposal of a plate and screw view, focusing on the accuracy of reduction and proper placement of the PHILOS plate to prevent the complications previously described.

Surgical Technique for Open Reduction-Internal Fixation of an Unstable Displaced 3-Part Proximal Humeral Fracture Using a Proximal Humeral Locking Plate.

The proximal humeral locking plate (PHLP) is a recently developed fixed-angle implant that is an option for open reduction-internal fixation of an unstable displaced proximal humeral fracture. Various articles have reported successful outcomes using the PHLP when compared with other implant designs. However, many complications still occur with use of the PHLP, such as avascular necrosis of the humeral articular fragment, malreduction (particularly varus malalignment), and screw penetration. These complications are related to the difficulty in fixation of this particular type of fracture, as well as ineffective surgical technique. We have therefore proposed a step-by-step surgical technique for open reduction-internal fixation of an unstable displaced 3-part proximal humeral fracture using a PHLP. This technique focuses on the precise placement of the PHLP according to the plate design, as well as an effective intraoperative assessment, to improve surgical outcomes and prevent the various complications of proximal humeral fractures.
