Vertical rib plating for the treatment of slipping rib syndrome

Costal margin reconstruction for slipping rib syndrome: Outcomes of more than 500 cases and advancements beyond earlier sutured repair technique

Objectives

To evaluate results of sutured repair for slipping rib syndrome (SRS), identify failure points, and discuss technique modifications to improve outcomes through costal margin reconstruction (CMR).

Methods

Patients undergoing repair of SRS between February 2019 and February 2024 at an academic referral institution were retrospectively analyzed. Pain scores, quality of life, pain medication use, and reoperations were evaluated pre- and postoperatively at 1 and 6 months. In patients failing sutured repair we identified specific failure points and devised a new CMR technique to overcome them. Subsequent CMR patients were followed at 1, 6, 12, 18, and 24 months using the same outcome measures.

Results

Four hundred forty-nine patients underwent repair. Two hundred forty-one patients underwent sutured repair with revision required in 66. Median time to revision was 14 months. CMR was developed and performed in 247 patients. In CMR patients, preoperative mean pain score of 7.5 out of 10 dropped postoperatively to 4.0, 2.5, 1.9, 1.3, and 0.9 at 1, 6, 12, 18, and 24 months, respectively (P < .001). Mean quality of life of 38% improved to 73%, 83%, 88%, 93%, and 95% at the same intervals (P < .001). Preoperatively, 29% of patients chronically used opioid medications. Opioid use dropped postoperatively to 11%, 4%, 4%, 0%, and 0% at the same intervals. Use of nonopioid medications followed a similar pattern. One CMR patient required full revision.

Conclusions

SRS is a debilitating, but correctable disorder. Improved pain and quality of life, reduction in chronic opioid use, and freedom from revision surgery suggest that CMR should be considered the standard operation for SRS.

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.

Dynamic musculoskeletal ultrasound: slipping rib, muscle hernia, snapping hip, and peroneal tendon pathology

Dynamic musculoskeletal ultrasound is an important diagnostic tool that allows the practitioner to observe soft tissue structures over a range of motion and identify pathology not diagnosed on other modalities. Familiarity with this modality allows health care practitioners to appropriately refer patients for this type of examination. This article will review several indications for dynamic ultrasound imaging, including slipping rib, muscle hernia, snapping hip, and peroneal tendon pathology. The examination technique and expected findings for common pathology in each location are discussed.

Initial outcomes using cryoablation in surgical management of slipping rib syndrome

INTRODUCTION

Minimally invasive repair of pectus excavatum (MIRPE) and cartilaginous rib excision (CRE) for slipping rib syndrome (SRS) are painful procedures. Intercostal nerve cryoablation (Cryo) controls pain and decreases opioid use in MIRPE. Herein, we describe our experience with cryoablation in CRE.

METHODS

A retrospective chart review was performed of all patients undergoing CRE between 2018 and 2022. Data on demographics, clinical characteristics, operative details, and hospital course were collected.

RESULTS

A total of 98 patients underwent CRE: 68 CRE without cryo, 22 CRE + Cryo, and 8 combined MIRPE + CRE + Cryo. Ninety percent of patients underwent bioabsorbable rib plating. Patients were predominantly female (79%, 73%, 50% respectively) with median ages 17.6, 16.9, and 14.2 years respectively. CRE + Cryo patients used significantly less opioids in hospital (0.6 OME/kg [0.1,1.2]) compared to CRE without cryo (1.0 OME/kg [0.6,2.1]), p < 0.05. The median length of stay (LOS) in CRE + Cryo was 1 day [1,2] compared to 2 days in CRE without cryo [1,2], p = 0.09. MIRPE + CRE + Cryo patients used 0.6 OME/kg [0.2,8.0] with a 2 day [1,5.5] LOS. Ninety-one percent of Cryo patients had cryoablation of T9 and/or T10 intercostal nerves, with no documented abdominal wall laxity at median follow-up of 16 days. Cryo was applied extra-thoracically in CRE + cryo without thoracoscopy or lung isolation, while MIRPE + CRE + Cryo used a combination extra-/intra-thoracic cryoablation in with thoracoscopy.

CONCLUSION

Intercostal nerve cryoablation reduces opioid use and LOS in patients undergoing cartilaginous rib excision for slipping rib syndrome. Cryotherapy to as low as T10 did not result in abdominal wall laxity and can be applied extra-thoracically without the need for thoracoscopy. Ongoing prospective studies are required to assess the long-term outcomes.

Síndromes por atrapamiento del nervio intercostal y sus ramas

Musculoskeletal chest pain poses a broad differential diagnosis, among which intercostal nerve involvement stands out. Its entrapment or that of any of its branches can resemble visceral pain and therefore can easily go unnoticed. With a good examination and the use of dynamic ultrasound, the diagnostic approach can be simpler. We present a 40-year-old man evaluated in a rehabilitation department for right lower rib pain, triggered by certain movements and associated with a pectus excavatum type thoracic deformity. Using dynamic ultrasound maneuvers, he was diagnosed with neuralgia of the 7th right intercostal nerve secondary to dynamic entrapment in the context of a thoracic deformity with costal hypermobility. We describe the clinical presentation, ultrasound imaging, treatment, and evolution after treatment. In this case, we describe entrapment syndromes of the intercostal nerve and its branches, their clinical and ultrasound diagnosis, and their therapeutic approach.

Combined Excision of Costal Cartilage and Rib Plating For Slipped Rib Syndrome

Slipped rib syndrome is often underdiagnosed and can be a source of significant discomfort and frustration for patients. Multiple conservative treatment approaches and surgical procedures have been described in the literature without a definitive standard. We present a case report utilizing two surgical techniques. This includes the excision of the affected costal cartilage in conjunction with placement of bioabsorbable rib plates. This technique could reduce the risk of recurrence as well as restore normal chest wall structure and function.
