Costal cartilage resection for the treatment of slipping rib syndrome (Cyriax syndrome) in adults

A Review of Slipping Rib Syndrome: Diagnostic and Treatment Updates to a Rare and Challenging Problem

Slipping rib syndrome (SRS) is a disorder that occurs when one or more of the eighth through tenth ribs become abnormally mobile. SRS is a poorly understood condition leading to a significant delay in diagnosis and therapeutic management. History and a physical exam are usually sufficient for a diagnosis of SRS. The utility of dynamic ultrasounds has also been studied as a useful diagnostic tool. Multiple surgical techniques for SRS have been described within the literature. Cartilage rib excision (CRE) has been the most common technique utilized. However, the literature has shown a high rate of recurrence and associated risks with the procedure. More recently, minimally invasive rib fixation and costal cartilage excision with vertical rib plating have been shown as successful and safe alternative techniques. This may be an effective, alternative approach to CRE in adult and pediatric populations with SRS.

Redefining the costal margin: A pilot study

BACKGROUND

Classical teaching of rib anatomy contends that the false ribs (7th to 10th) fuse anteriorly to form the costal margin of the chest. Slipped rib syndrome consists of false rib subluxation into the thorax with symptomatic impingement of the intercostal nerve. We sought to determine the incidence of this anatomic finding through anatomic study of the costal margin.

METHODS

Cadavers were evaluated for mobility and attachment of the ninth and tenth ribs. Experienced anatomists and chest wall surgeons conducted a standardized dissection and assessed rib tip mobility using predefined criteria. Videos of dissections were submitted to a single investigator who reviewed the findings.

RESULTS

Costal margins of 40 cadavers (45% male) were evaluated bilaterally. The average age was 83 years ± 11 years. The ninth rib was found to be attached to the eighth rib 100% of the time by an interchondral cartilaginous attachment along the body of the eighth and ninth ribs. Internal subluxation was noted in 19% (15 of 80), and the tip of the rib was mobile in 86% (69 of 80) evaluations. The tenth rib was attached to the ninth rib in 18%(14/80). A "floating" 10th rib was noted in 59% (47 of 80) of specimens. Subluxation was noted in 33% (26 of 60). Half of the ribs that subluxed moved medially to the ninth rib and half moved externally. An upwardly hooked tip was noted in 10% (8 of 80). Ribs with a hooked tip subluxed in 63% (5 of 8), and all of these ribs (5 of 5) moved to the interior of the chest ( p = 0.020).

CONCLUSION

The ninth rib is commonly attached to the eighth rib, but the tenth rib is often not attached to the ninth rib. Most commonly, the tenth rib is a "floating" rib. Internal subluxation of the tenth rib as well as the presence of a hooked tip may predispose individuals to the development of "slipped rib syndrome."

Slipping rib syndrome: A clinical and dynamic-sonographic entity. A serial cases report

BACKGROUND

Slipping rib syndrome (SRS) consists of false or floating rib hypermobility, which can force the ribs to come into contact with each other.

OBJECTIVE

We aimed to examine each case by dynamic ultrasound to determine their ultrasound characteristics and analyze the clinical features of patients with SRS in order to better manage and follow them up.

METHODS

Retrospectively, we collected 14 case series presenting to SRS between June 2016 and September 2018. The diagnosis was clinical and confirmed by dynamic ultrasound maneuvers.

RESULTS

The mean age was 35.00 ± 10.66 years and 64.29% was male. The pain mechanism was caused by repetitive movements or a traumatic event. Dynamic ultrasound was considered a very useful tool for the diagnosis. Different conservative treatments were applied in most cases. Eco-guided infiltration was also an option.

CONCLUSIONS

SRS should initially be based on a clinic suspicion in order to achieve a correct diagnosis and management. It is an underdiagnosed syndrome, so these case series contribute to our knowledge regarding this syndrome.

Vertical rib plating for the treatment of slipping rib syndrome

BACKGROUND

Slipping rib syndrome (SRS) is a painful condition of hypermobile, detached lower costal cartilages impinging the intercostal nerves. While surgical resection of the cartilaginous rib is reported as definitive treatment, recurrent symptoms are common. We describe the addition of vertical bioabsorbable rib plating to decrease recurrence.

METHODS

An IRB-approved (#17-098), single institution, retrospective chart review was performed for patients who presented with SRS from 2009 to 2019 at a single institution. Descriptive statistics were used to compare patients with and without bioabsorbable vertical plating.

RESULTS

A total of 85 patients (71.8% female, mean age 17.7 years) underwent evaluation for SRS. Of the 70 who underwent surgery solely for SRS, 29 (41%) underwent vertical rib plating at initial surgery while 41 (58.6%) did not. Recurrent symptoms developed in 7 (17.1%) unplated patients, while only 1 (3.4%) plated patient had recurrent SRS (which occurred after a motor vehicle crash) (p = 0.0116). Of the 8 with recurrent symptoms, 3 underwent vertical plating at a subsequent operation.

CONCLUSION

Rate of recurrent symptoms after cartilage resection alone for SRS was 17.1%. The addition of vertical rib plating with bioabsorbable plates decreased recurrent symptoms and improved outcomes.

Sports Medicine-Related Breast and Chest Conditions-Update of Current Literature

ABSTRACT

This article reviews the most up-to-date evidence-based recommendations pertaining to breast and upper chest conditions, specifically for the sports medicine physician. Because of the unique circumstances of the team physician, they can see a wide breadth of pathology. Athletes may not have a primary care physician and may prefer to present to their team physician for breast and upper chest conditions. It is often more comfortable and convenient for athletes to seek treatment in the team setting. Therefore, it is important that the medical professional be aware of not only common pathology but also of that which is rarer. Any delay in evaluation can result in unnecessary morbidity and lead to complications or extended time lost from sport. Consequently, it also is important to facilitate an atmosphere encouraging early presentation and workup.
