Post-traumatic intercostal and diaphragm hernias following a sneezing episode.

Trauma and sneeze-induced or cough-induced intercostal and diaphragm hernias are both rare phenomena, especially in combination. Management of these hernias is not well described, and there is no good evidence to guide operative management. Here we describe a rare presentation of coexisting intercostal and diaphragm hernias and surgical management with primary repair via a thoracotomy.

Use of a Capture-Guidance Surgical Instrument to Minimize Muscle Stripping During Nuss Repair of Pectus Excavatum.

Background: Pectus excavatum is an anomaly of chest wall development in which anterior ribs curve inward and the sternum is displaced toward the vertebral column. The Nuss procedure is a minimally invasive technique in which one or more metal bars are implanted to brace the sternum in a corrected position. Over time, the chest wall remodels into an anatomically corrected shape and the bar(s) are removed at a later date. During the procedure, passage of an introducer instrument and then the repair bar(s) may shear the intercostal muscles from the adjacent ribs. This creates larger than necessary defects in the chest wall, improper or unstable bar placement, and inadequate repair. Instrument Design: We report a new surgical instrument for guiding the introducer through the contralateral chest wall. This capture-guidance instrument (CGI) redirects and channels forces to keep the introducer true while preventing muscle stripping during passage of the introducer and repair bar(s). Instrument Use: The CGI has been piloted at two pectus centers with a notable decrease in intercostal muscle stripping. Conclusion: The CGI addresses the problem of shear and intercostal muscle stripping during traversal of the chest as part of Nuss repair of pectus excavatum.

Unifying classification for transdiaphragmatic intercostal hernia and other costal margin injuries.

OBJECTIVES: Taxonomy of injuries involving the costal margin is poorly described and surgical management varies. These injuries, though commonly caused by trauma, may also occur spontaneously, in association with coughing or sneezing, and can be severe. Our goal was to describe our experience using sequential segmental analysis of computed tomographic (CT) scans to perform accurate assessment of injuries around the costal margin. We propose a unifying classification for transdiaphragmatic intercostal hernia and other injuries involving the costal margin. We identify the essential components and favoured techniques of surgical repair. METHODS: Patients presenting with injuries to the diaphragm or to the costal margin or with chest wall herniation were included in the study. We performed sequential segmental analysis of CT scans, assessing individual injury patterns to the costal margin, diaphragm and intercostal muscles, to create 7 distinct logical categories of injuries. Management was tailored to each category, adapted to the individual case when required. Patients with simple traumatic diaphragmatic rupture were considered separately, to allow an estimation of the relative incidence of injuries to the costal margin compared to those of the diaphragm alone. RESULTS: We identified 38 patients. Of these, 19 had injuries involving the costal margin and/or intercostal muscles (group 1). Sixteen patients in group 1 underwent surgery, 2 of whom had undergone prior surgery, with 4 requiring a novel double-layer mesh technique. Nineteen patients (group 2) with diaphragmatic rupture alone had a standard repair. CONCLUSIONS: Sequential analysis of CT scans of the costal margin, diaphragm and intercostal muscles defines accurately the categories of injury. We propose a 'Sheffield classification' in order to guide the clinical team to the most appropriate surgical repair. A variety of surgical techniques may be required, including a single- or double-layer mesh reinforcement and plate and screw fixation.

Decreased Hip Internal Rotation Increases the Risk of Back and Abdominal Muscle Injuries in Professional Baseball Players: Analysis of 258 Player-seasons.

INTRODUCTION: The relationship of hip range of motion (ROM) to shoulder, elbow, abdominal, and back injuries remains undefined. METHODS: We assessed hip ROM on players reporting to Major League Spring Training for an organization over six seasons (2010 to 2015). Hip ROM was correlated with player abdominal, back, shoulder, and elbow injury status for those seasons using multivariate binomial logistic regression analysis. RESULTS: A total of 258 player-seasons (129 pitchers and 129 position players) resulted in 20 back and 35 abdominal injuries across all players and 28 elbow and 25 shoulder injuries in pitchers. Hip ROM did not correlate with shoulder or elbow injuries. Hip internal rotation deficit of 5° correlated with core injury (odds ratio [OR], 1.40; P = 0.024 for pitchers; OR, 1.35; P = 0.026 for position players) and back injury (OR, 1.160; P = 0.022 for pitchers). DISCUSSION: Hip internal rotation deficits were predictive of back and abdominal injuries but not shoulder or elbow injury.

Diaphragmatic and intercostal muscle tear after an episode of violent sneezing: spontaneous diaphragmatic injury.

Spontaneous diaphragmatic injuries are rare, accounting for approximately 1% of all diaphragmatic injuries. We report a case of a 69-year-old male with a concurrent lower respiratory tract infection who sustained diaphragmatic and intercostal muscle injuries after an episode of violent sneezing. To our knowledge, this is the first reported case of spontaneous diaphragmatic injury after sneezing.

Postpneumonectomy cavity herniation through an intercostal space.

Mediastinal shift is common after pneumonectomy and herniation of the remaining lung into the opposite hemithorax has consequently been reported. In this case, we present the herniation of the pneumonectomy cavity contained by the calcified pleura through an intercostal space, in a patient who has undergone a left pneumonectomy 47 years previously. We repaired the intercostal muscular defect using a Mersuture mesh. The patient did well and there was no postoperative pain.

Dose response effect of cement dust on respiratory muscles competence in cement mill workers.

Electromyography (EMG) of respiratory muscles is a reliable method of assessing the ventilatory muscle function, but still its use has not been fully utilized to determine the occupational and environmental hazards on respiratory muscles. Therefore, EMG of intercostal muscles was performed to determine the dose response effect of cement dust on respiratory muscles competence. Matched cross-sectional study of EMG in 50 non-smoking cement mill workers with an age range of 20 - 60 years, who worked without the benefit of cement dust control ventilation or respiratory protective devices. EMG was performed by using surface electrodes and chart recorder. Significant reduction was observed in number of peaks (p < 0.0005), maximum peak amplitude (p < 0.0005), peak-to-peak amplitude (p < 0.0005) and duration of response (p < 0.0005) in cement mill workers compared to their matched control. Cement dust impairs the intercostal muscle competence and stratification of results shows a dose-effect of years of exposure in cement mill.

Rib impingement in first class cricketers: case reports of two patients who underwent rib resection.

Two first class cricket bowlers presented with costoiliac pain secondary to rib impingement. In both patients, conservative management of the injury had failed to improve symptoms. Surgical resection of the affected rib was undertaken. At follow up, both patients had made a good recovery and had returned to competitive cricket.
