Treatment of suprascapular nerve entrapment syndrome.

Suprascapular nerve entrapment syndrome (SNES) is an often-overlooked etiology of shoulder pain and weakness. Treatment varies depending on the location and etiology of entrapment, which can be described as compressive or traction lesions. In some cases, treating the primary cause of impingement (ie. rotator cuff tear, ganglion cyst, etc.) is sufficient to relieve pressure on the nerve. In other cases where impingement is caused by dynamic microtrauma (as seen in overhead athletes and laborers), treatment is often more conservative. Conservative first-line therapy includes rehabilitation programs, nonsteroidal anti-inflammatory drugs, and lifestyle modification. Physical therapy is targeted at strengthening the rotator cuff muscles, trapezius, levator scapulae, rhomboids, serratus anterior, and deltoid muscle(s). If non-operative treatment fails to relieve suprascapular neuropathy, minimally invasive treatment options exist, such as suprascapular nerve injection, neurostimulation, cryoneurolysis, and pulsed radiofrequency. Multiple treatment modalities are often used synergistically due to variations in shoulder anatomy, physiology, pain response, and pathology as a sole therapeutic option does not seem successful for all cases. Often patients can be treated with non-invasive measures alone; however, injuries refractory to conservative treatment may require either arthroscopic or open surgery, particularly if the patient has an identifiable and reversible cause of nerve compression. Indications for invasive treatment include, but are not limited to, refractory to non-operative treatment, have a space-occupying lesion, or show severe signs and symptoms of muscle atrophy. Open decompression has fallen out of favor due to the advantages inherent in the less invasive arthroscopic approach.

Bioinductive Collagen Implant Augmentation for the Repair of Chronic Lower Extremity Tendinopathies: A Report of Two Cases.

In this report, we present two cases of refractory chronic lower extremity tendinopathies treated with collagen bioinductive implant augmentation: a 20-year-old male football player with chronic patellar tendinopathy and a 40-year-old active female with chronic proximal hamstring tendinopathy. We demonstrate that bioaugmentation may represent an effective strategy in the surgical treatment of chronic tendinopathies. Both patients were able to return to their pre-injury activity levels at an accelerated rate.

Rare presentation of bilateral thumb psoriatic arthritis treated with arthrodesis: a case report.

Psoriatic arthritis (PsA) is a seronegative inflammatory arthritis that occurs concomitantly with cutaneous manifestations and tendinous pathology that affects up to 1% of the general population. While the majority of cases are mild, nearly 20% of PsA patients will progress to severe disease manifesting as debilitating polyarticular inflammation and joint destruction. PsA is most commonly asymmetric and bilateral severe disease involving the same joints in each hand has rarely been reported in the literature. It is estimated that PsA only presents bilaterally in a quarter of patients. The recent increase in popularity and efficacy of disease-modifying anti-rheumatic drugs (DMARDs) has led to increasing rarity of such severe disease progression. We present a case of a 47-year-old male with PsA who had a unique pattern of bilateral first metacarpophalangeal (MP) and interphalangeal (IP) involvement with minimal erosion leading to significant joint pain, instability, dislocation, and loss of function. After failure of conservative treatment that included both DMARDs and non-steroidal anti-inflammatory drugs (NSAIDs), the patient opted for surgical management. The purpose of this report is to identify a rare presentation of PsA and consider the significance of MP joint arthrodesis as a viable treatment to restore functional status and improve quality of life.

Robotics in spinal surgery.

Although the da Vinci robot system has garnered much attention in the realm of surgery over the past few decades, several new surgical robotic systems have been developed for spinal surgery with varying levels of robot autonomy and surgeon-specified input. These devices are currently being considered as potential avenues for increasing the precision of any surgical intervention. The following review will attempt to provide an overview of robotics in modern spine surgery and how these devices will continue to be employed in various sectors across the field.
