Ossified bifid superior transverse scapular ligament causing a double suprascapular foramen is a very rare finding. This ossified ligament reduces the suprascapular space by half of its original size. It is one of the precipitating factors of suprascapular nerve entrapment. Here we describe a double suprascapular foramen in a dry left scapula of Indian origin. There were two bony bars bridging the suprascapular notch thereby making two foramina. The bony bars were 'V' shaped with its apex attached to the lateral side of the suprascapular notch. The upper foramen was large and triangular whereas the lower foramen was small and oval. Considering the shape of the foramen and the 'V' shaped attachment of the bony bars, we conclude it to be due to the ossification of bifid superior transverse scapular ligament. A double suprascapular foramen should always be kept in mind while diagnosing and treating suprascapular nerve entrapment. Knowledge about the double suprascapular foramen would be useful to orthopaedic surgeons who perform decompression for suprascapular nerve entrapment through arthroscopy and open procedures.

Damage to the upper trunk of the brachial plexus, often caused by high-energy trauma, leads to significant functional impairment of the upper limb. This injury primarily affects the C5 and C6 roots, resulting in paralysis of muscles critical for shoulder and elbow function. If spontaneous nerve regeneration does not occur within 3-6 months post-injury, surgical intervention, including nerve transfers, is recommended to restore function.

There are insufficient studies directly comparing the superiority of suprascapular nerve block (SSNB) and intra-articular shoulder injection (IAI) techniques, which are frequently used interventional methods in treatment.

Introduction: Shoulder pain is the third leading cause of musculoskeletal complaints in primary care clinics. Its prevalence varies from 14% to 34%. Among all the structures that can cause shoulder pain, the most vulnerable to injury is the tendon of the supraspinatus muscle.

This study aimed to gather preferred reconstructive strategies from BPI surgeons for actual cases from a multicenter cohort to identify areas of agreement.
Methods: Four case files (history, physical examination, and imaging and electrodiagnostic testing results) were distributed to eight self-designated Level IV expert BPI surgeons in the United States.

Background: This study aims to investigate the efficacy of five analgesic strategies combined with conventional physiotherapy program (CPT) in managing chronic shoulder pain.
Methods: Two authors independently screened studies, extracted data using a pre-formatted chart, and assessed bias using the Cochrane Risk of Bias tool. A network meta-analysis was performed by the Stata 17.
