Objective: Pain relief and improvement of hand function by ganglion cyst resection and/or creation of a dorsal capsular window with partial synovectomy. In the case of visible ganglion cysts consideration of aesthetic aspects., Indications: Visible and occult persisting dorsal wrist ganglion cysts, recurrent ganglion cyst after open or arthroscopic resection and intraosseous ganglion cyst with an extraosseous portion., Contraindications: Recent skin lesion of the wrist., Surgical Technique: Standard setting for wrist arthroscopy. Portals: radiocarpal 3‑4 and 6R, midcarpal radial (RMC) and midcarpal ulnar (UMC) portals. Start with arthroscopy in 3‑4 portal. If there is insufficient visualization of the dorsal capsular fold, change the arthroscope to the 6R portal. From here a tangential view onto the dorsal capsule at the level of the scapholunate (SL) ligament can be obtained. If a large ganglion overlying the 3‑4 portal or the RMC portal is present, UMC portals are primarily used. Intra-articular visualization of ganglion structures should always be attempted, especially for occult ganglion cysts. If the radiocarpal findings are inconspicuous, midcarpal arthroscopy from the UMC portal is performed to visualize the dorsal capsule at the SL ligament. Depending on the main localization of the visible alterations, ganglion or thickening of the capsule, a dorsal capsular window is created at the level of the SL ligament either radiocarpal or midcarpal or overlying both joints. Complete resection of the ganglion is controlled by palpation. Use of a 2.4 mm arthroscope with 30° angle of vision and 2.5 mm shaver (aggressive cutter). Low-suction drainage and soft padded dressing. An arthroscope with 70° angle of vision enables an even better view onto the dorsal capsule., Postoperative Management: Immediate wrist mobilization, avoidance of excessive loading for 3 weeks. Physiotherapy is necessary if wrist flexion is not regained 3  weeks postoperatively., Results: From 2007 to 2010 a total of 92 wrists from 88 patients were treated by arthroscopic ganglion cyst resection, 44 % for occult and 17 % for recurrent ganglia. At a mean follow-up of 78 % after 29.5 months a high patient satisfaction of 90 % was achieved. The only complication was a complex regional pain syndrome (CRPS) in one patient. The recurrence rate was 12.5 %.

Purpose: To review the clinical outcomes of treatment for adult wrist ganglions and to conduct a meta-analysis comparing the 2 most common options: open surgical excision and aspiration., Methods: The review methodology was registered with PROSPERO. We performed a systematic search of MEDLINE and EMBASE for articles published between 1990 and 2013. Included studies reported treatment outcomes of adult wrist ganglions. Two independent reviewers performed screening and data extraction. We evaluated the methodological quality of randomized controlled trials (RCT) and cohort studies using the Cochrane Handbook for Systematic Reviews and the Newcastle-Ottawa Scale, respectively; Grading of Recommendations, Assessment, Development, and Evaluation was used to evaluate the quality of evidence., Results: A total of 753 abstracts were identified and screened; 112 full-text articles were reviewed and 35 studies (including 2,239 ganglions) met inclusion criteria for data extraction and qualitative synthesis. Six studies met criteria for meta-analysis, including 2 RCTs and 4 cohort studies. In RCTs surgical excision was associated with a 76% reduction in recurrence compared with aspiration. Randomized controlled trial quality was moderate. In cohort studies surgical excision was associated with a 58% reduction in recurrence compared with aspiration. Cohort study quality was very low. In cohort studies aspiration was not associated with a significant reduction in recurrence compared with reassurance. Across all studies mean recurrence for arthroscopic surgical excision (studies, 11; ganglions, 512), open surgical excision (studies, 14; ganglions, 809), and aspiration (studies, 12; ganglions, 489) was 6%, 21%, and 59%, respectively. Mean complication rate for arthroscopic surgical excision (studies, 6; ganglions, 221), open surgical excision (studies, 6; ganglions, 341), and aspiration (studies, 3; ganglions, 134) was 4%, 14%, and 3%, respectively., Conclusions: Open surgical excision offers significantly lower chance of recurrence compared with aspiration in the treatment of wrist ganglions. Arthroscopic excision has yielded promising outcomes but data from comparative trials are limited and have not demonstrated its superiority. Further RCTs are needed to increase confidence in the estimate of effect and to compare complications and recovery., Type of Study/level of Evidence: Therapeutic I., (Copyright © 2015 American Society for Surgery of the Hand.

In arthroscopic wrist surgery, the resection of dorsal wrist ganglia has become a well accepted practice. As advantages for the minimally invasive procedure the low complication rate and low postoperative morbidity, less postoperative pain and faster recovery over open techniques are discussed. The possibility to assess accompanying joint pathology is considered as another advantage. The importance of identifying a so-called ganglion cyst stalk seems to have been overstated. Regarding the technique, the main discussion points are the size and localisation of the capsular window and the necessity of additional midcarpal arthroscopy. The possibility and results of treatment of recurrent ganglion cysts are still controversial. Our own experience and that of some authors are positive. Hardly mentioned in the literature is the treatment of occult dorsal wrist ganglia and its results, which is considered as very successful by the authors., (© Georg Thieme Verlag KG Stuttgart · New York.)

Most patients with symptoms related to the carpal tunnel have idiopathic median nerve compression. Imaging has little role in the care of most cases because steroid injection, therapeutic ultrasound, and surgery have established roles. However, cases with atypical presentation, mass lesions, synovitis, or failed carpal tunnel surgery will benefit from imaging. In this article we review the anatomy of the carpal tunnel, the diseases affecting this region, and then discuss the use of conventional radiographs, computed tomography, ultrasound, and magnetic resonance imaging (MRI), outlining the strengths and weaknesses of each method while listing the signs of disease. We conclude that both ultrasound examination and MRI are powerful and often complementary techniques., (Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.)

A case of multifocal and recurrent ganglion cysts is described. An 11-year-old boy was referred because of symptomatic cystic masses in the extremities since the age of 2 years. Over the years, he had experienced intermittent appearance of these lesions, which were associated with pain, but without any systemic manifestations. Magnetic resonance imaging (MRI) showed cystic lesions with synovio-capsular thickening along the temporomandibular joints (TMJ), atlanto-axial synovial articulation, and tendons and joints of the right wrist and hand. Histopathological examination of one lesion showed anastomosing fibro-connective tissue surrounded by a wall of smooth muscle and fibrous connective tissue, findings that were consistent with ganglion cyst. The early onset of the disease, as well as the involvement of multiple and unusual sites, including the TMJ, implies a genetic susceptibility to these lesions that we refer to as 'cystic ganglionosis'.

Objective: The purpose of our study was to determine if preoperative MRI can differentiate between occult ganglion and synovitis in the chronic painful wrist., Conclusion: MRI is accurate in preoperatively distinguishing between ganglion and synovitis in the setting of chronic dorsal wrist pain. Four main criteria were useful: margin, shape, internal structure, and enhancement after administration of contrast material, with shape and internal structure being most helpful.

We report an abnormal muscle on the radial aspect of the wrist, which presented clinically as a ganglion and radial wrist pain. Existence of muscles in the first compartment has been accounted earlier, however its atypical presentation advocates its inclusion in the differential diagnosis of a dorso-radial ganglion and wrist pain.

Magnetic resonance imaging (MRI) was performed on the wrists of 103 asymptomatic volunteers. The images were evaluated independently by two musculoskeletal radiologists and one orthopaedic surgeon. Wrist ganglia were identified in 53 out of the 103 wrists. The average long and short axes measurements were 8 mm (range 3-22) and 3 mm (range 2-10), respectively. Seventy per cent of the ganglia originated from the palmar capsule in the region of the interval between the radioscaphocapitate ligament and the long radiolunate ligament. Fourteen per cent of the ganglia were dorsal and originated from the dorsal, distal fibres of the scapholunate ligament. Two ganglia had surrounding soft tissue oedema and one had an associated intraosseous component. Unlike previous surgical and pathological series, our study showed that palmar wrist ganglia are more common than dorsal wrist ganglia. The vast majority of these asymptomatic ganglia occur without associated ligamentous disruption, soft tissue oedema or intraosseous communication.

The wrist is a complex structure with an extensive differential diagnosis for a presenting mass. However, the vast majority of hand and wrist masses are benign, and many of these have a distinctive radiographic appearance. In this article, the imaging characteristics of the most common entities are reviewed with particular attention to magnetic resonance appearance. The 3 most common hand and wrist lesions include ganglion cysts, giant cell tumors of the tendon sheath, and hemangiomas. Other common lesions that can be diagnosed radiographically include lipomas, neural sheath tumors, infection and inflammation, and variant soft-tissue or bony structures. The appearance of the fibrolipomatous hamartoma will also be demonstrated because this is a radiographically distinctive, though rare, lesion.

Ganglions occur commonly in the wrist and arise from the radiocarpal and intercarpal joints. Although ganglions present commonly as masses on the dorsal or volar surface of the wrist, ganglions from wrist joints appear rarely at other locations in the hand. We report 2 cases of ganglions arising from wrist joints that presented as painless masses in the center of the palm without signs or symptoms of median or ulnar nerve compression. Surgical treatment required extensile exposure to trace the proximal stalks to their joints of origin. Knowledge of the possibility that a painless mass in the palm could be a ganglion arising from a joint in the wrist allows proper presurgical planning and informed consent.
