Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The size of the sample was determined by the preliminary statistical study conducted using the NCSS-PASS 12 program, and will consist of 84 patients.
Patients will be randomly allocated to one of two groups. Local platelet rich plasma (PRP) injection in the first group (n = 42) and local steroid injection in the second group (n = 42) will be performed once into the carpal tunnel. PRP will be obtained by centrifugation of autologous anticoagulated whole blood. 6.43 mg of betamethasone dipropionate and 2.63 mg of betamethasone sodium phosphate will be administered as local steroids. Both groups will be recommended a resting splint for use in the day time when possible and at night time. Clinical and electrophysiological evaluations of all patients will be performed by a researcher who is blinded to the treatment received by the patient. The electrophysiological and clinical evaluations of the patients will be done by the same investigator before and after the 1st and 3rd months of therapy. At one and three month follow up, Symptom severity and functional capacity will be assessed using the Boston Carpal Tunnel Syndrome Questionnaire. The hand grip strength of the patients will be assessed using a Jamar hand dynamometer ( (Baseline hydraulic hand dynomometer, Irvington, NY, USA) and the finger holding power by pinchmeter. Conventional motor and sensory nerve conduction studies will be applied as electrodiagnostic studies.

Platelet rich plasma (PRP) -T lab PRP kit
A single 1ml PRP extract injection will be will be injected into the carpal tunnel of the wrist in which a diagnosis of carpel tunnel syndrome has been established. A 23 gauge needle will used to perform the injection through the distal wrist creased into the carpal tunnel. performed once into the carpal tunnel in the wrist . PRP will be obtained by centrifugation of autologous anticoagulated whole blood.
Local platelet rich plasma (PRP) injection-T-Lab PRP kit
Platelet rich plasma (PRP) will be obtained by centrifugation of autologous anticoagulated whole blood. 1 ml PRP extract will be injected into the carpel tunnel (of the side with a diagnosis of carpel tunnel syndrome) via the distal wrist line using 23 gauge needle.
Diprospan ®, Schering Plough
A single steroid injection (1 ml Diprospan ®, Schering Plough containing 6.43 mg of betamethasone dipropionate and 2.63 mg of betamethasone sodium phosphate) will be injected into the carpal tunnel of the wrist in which a diagnosis of carpel tunnel syndrome has been established. A 23 gauge needle will used to perform the injection through the distal wrist creased into the carpal tunnel.
Local steroid injection-Diprospan ®, Schering Plough
The local steroid injection ((1 ml Diprospan ®, Schering Plough containing 6.43 mg of betamethasone dipropionate and 2.63 mg of betamethasone sodium phosphate) will be performed once into the carpal tunnel.1 ml Diprospan ®, Schering Plough extract will be injected by using 23 gauge needle from the distal wrist line through the carpal tunnel only once.
