Treatment of wrist dorsal ganglion cyst. Randomized clinical trial.

INTERVENTION: C04.182.867 D06.472.040 D09.947.875.359.448 E04.237.890 The aspiration group: 68 patients with dorsal arthrosynovial cyst, local anesthesia with lidocaine will be performed and after aspiration of the cyst with a 40x12mm needle and after dressing, follow‐up will be at 1, 3, 6 and 12 months. The Aspiration and Infiltration group with corticosteroids (methylpredinisone 40mg / 2ml: 68 patients with dorsal arthrosynovial cyst of the wrist confirmed by ultrasound, local anesthesia with lidocaine will be performed and after aspiration of the cyst with 40x12mm needle and then infiltration of 1 to 2 ml of methylpredinisone 40mg / 2ml and after dressing, follow‐up will be at 1, 3, 6 and 12 months.The Aspiration and infiltration and infiltration group with 75% hypertonic glucose: 68 patients with dorsal arthrosynovial cyst of the wrist confirmed by ultrasound, local anesthesia with lidocaine and after aspiration of the cyst with a 40x12mm needle and then infiltration of 1 to 2 ml of 75% hypertonic glucose and after dressing, follow‐up will be at 1, 3, 6 and 12 months CONDITION: M00‐M99 Other bursal cyst : The problem to be studied will be the dorsal synovial cyst of the wrist, it will be performed in healthy patients with dorsal arthrosynovial cyst confirmed by ultrasound, and without previous treatment PRIMARY OUTCOME: Comparatively assess which group had a higher cure rate, simple aspiration group, aspiration group with corticosteroid infiltration (methylpredinisone 40mg / 2ml) or aspiration and infiltration with 75% hypertonic glucose after 1 year of follow‐up. SECONDARY OUTCOME: Ascertain the side effects of each treatment in the study: .this evaluation will be carried out through questions to the patient such as edema, pain and hyperemia and also through physical examination of the skin and skin necrosis or hypochromia will be evaluated. Functional analysis of the hand and wrist in relation to the treatment groups, the functional questionnaire will be carried out through the Brief Michigan Questionaire, the grip strength will be performed through the average force by the JAMMAR dynamometer, the pain will be assessed by the visual analog scale (VAS) ) which is numbered from 1 to 10 and lastly the range of motion of the wrist through a goniometer INCLUSION CRITERIA: Female and male patients without any previous treatment; wrist ultrasonography confirming the diagnosis of dorsal wrist ganglion cyst.
