Effectiveness of corticosteroid and 5% dextrose versus USG-guided ozone injections in patients with carpal tunnel syndrome: Three blind randomized studies

Various median nerve anatomical variations have been reported in the literature.One of these is the bifid median nerve.Due to its relatively higher cross-sectional area, it can facilitate compression of the median nerve in the carpal tunnel.Therefore, bifid median nerve is relatively common in patients with CTS.Some studies have shown that the bifid median nerve has an effect on surgical failure in the treatment of carpal tunnel syndrome.Apart from surgical treatment, perineural injection with corticosteroids is a treatment method that has been used for a long time in the treatment of mild and moderate carpal tunnel syndrome.It is controversial whether bifid median nerve has a negative effect on treatment effectiveness.When looking at the literature, there is no previous study on this subject.With the introduction of ultrasound into our daily practice, the frequency of ultrasound-guided perineural injections has increased.Ultrasound allowed us to see variations in the median nerve before injection.The aim of the study is to compare the effectiveness of steroid injection in patients with CTS with bifid median nerve and patients with CTS with non-variant median nerve.It is also to investigate whether this anatomical variation has a negative effect on the treatment.

The aim of the study is to evaluate the prevalence of bifid median nerve in patients diagnosed with carpal tunnel syndrome (CTS) and whether it has a higher prevalence in CTS patients than in asymptomatic individuals, and to evaluate the characteristics of the bifid median nerve found and whether median nerve variations are predisposing factors in the development of CTS.

Stroke, one of the most important causes of disability and death in the world, is an acute focal deficit of the central system caused by vascular origin such as cerebral infarction, intracerebral haemorrhage and subarachnoid haemorrhage. Hemiplegic shoulder pain, which is one of the most common complications after stroke, is an important problem affecting extremity rehabilitation. Although there are many factors thought to cause haemiplegic shoulder pain, there is still controversy about its treatment. Although there are many treatment strategies for this complication such as analgesics, antispasmotics, local corticosteroid injections, suprascapular nerve blockade, physical therapy modalities and exercise therapy, sometimes very resistant cases are also seen. For the treatment of persistent haemiplegic shoulder pain unresponsive to conventional treatment modalities, intra-articular injection of corticosteroids into the shoulder joint is commonly used, but its palliative effect has only a relatively short duration.Corticosteroids may also have adverse effects such as allergic reactions, rash, hyperglycaemia, menstrual disorders and adrenal suppression. Suprascapular nerve block is another option to relieve haemiplegic shoulder pain. The suprascapular nerve provides 70% of the sensory innervation of the shoulder joint. Thus, blocking pain transmission through the SS provides effective control of haemiplegic shoulder pain. However, the efficacy of suprascapular nerve block varies according to the study population and depends on the therapeutic modality to which it is compared. In addition, the effect of suprascapular nerve blockade may be limited due to the short duration of action of local anaesthetic agents. Neurolysis may cause permanent paralysis of the supraspinatus and infraspinatus muscles. For this reason, a deconstructive method is not preferred. Pulse RF applications, which is a non-deconstructive, neuromodulatory method, may be preferred in this regard. So far, there are very few studies investigating the efficacy of intra-articular steroid injection, suprascapular block and pulse RF in hemiplegic shoulder pain separately, but there is no study investigating the efficacy of Pulse RF treatment against other treatment methods together. In this study, investigator's aim was to compare the efficacy of suprascapular pulse radiofrequency against USG-guided suprascapular nerve block and intra-articular steroid injections in hemiplegic shoulder pain.

Radiofrequency (RF) application is a treatment method that temporarily blocks pain transmission in the nerve where the application is made, through the heat emitted by radio waves. Genicular nerve ablation with RF has recently become a promising treatment option for the treatment of chronic knee pain. These methods are based on the principle that interfering with the sensory nerve fibers of a painful structure can relieve pain and restore function. Their targets are sensory nerves located on the periosteum before entering the knee joint capsule. The knee joint is innervated by a complex nerve network called genicular nerves, which are articular branches of many nerves such as the femoral, tibial, peroneal, saphenous and obturator nerves. Some of the genicular nerves can be easily localized. The intermedius genicular nerve carries the sensation of subpatellar pain. The intermedius genicular nerve is located under the vastus intermedius muscle, anterior to the distal femoral shaft, just above the bony cortex. Targeting sensory nerves in addition to standard procedures and improving target identification using ultrasound guidance may increase treatment success. The aim of this study is to investigate the effect of ultrasound-guided genicular nerve radiofrequency therapy on pain and knee function by targeting only the traditional 3 genicular nerves and the intermedius genicular nerve in addition to the traditional genicular nerves in advanced gonarthrosis patients with prominent anterior knee pain.
