Surgical Repair for Rhomboid Major Tear: A Case Report.

Rhomboid tears are a rare type of tendon injury. Although rhomboid tears can present with periscapular pain and scapular dyskinesis, their clinical presentations and diagnostic procedures remain largely unknown. In addition, few reports are available on the surgical treatment of rhomboid tears. We report a rhomboid repair case for a complete rhomboid major tear diagnosed based on physical findings and magnetic resonance imaging (MRI). A 28-year-old man presented with right medial scapular pain that appeared after carrying a heavy box. He had right medial scapular tenderness, with worsening pain during shoulder joint elevation. The inferior pole of the right scapula was lateral compared with the left scapula, and a dent was observed on the medial scapula. Magnetic resonance imaging revealed a tear in the right rhomboid major at its insertion, with muscle retraction. Two months of conservative treatment failed to improve his symptoms; therefore, we performed a surgical repair. We created the bone holes on the medial border of the scapula and repaired the torn rhomboid major muscle to its insertion using the Krackow stitch technique. He had a satisfactory functional outcome without postoperative retearing. This case report provides new information on the clinical presentation and surgical procedure of rhomboid major tears and the first MRI finding that depicts a rhomboid tear clearly. In cases of rhomboid tears, persistent medial scapular pain and winging scapula can be clinically problematic, requiring surgery. In addition to physical findings, a periscapular MRI is useful in diagnosing rhomboid tears. The results of this case study suggest that surgical repair using locking sutures is an option for treating complete rhomboid tears with muscle retraction.
