In total, 38 patients with cystic dorsal wrist tumours managed with surgical excision were prospectively followed up for 2 years. Tissue was examined histologically after primary surgery and at recurrence. Two distinct tissue types were found: ganglion cyst and synovial cyst., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: As health care costs in the United States continue to rise, there is increasing attention on cost-saving measures. One area of investigation is the utility of pathologic examination of specimens from routine procedures with a suspected benign pathology. We assessed the utility and cost of routine pathologic analysis for wrist ganglion cyst excision., Methods: A retrospective cohort study of all wrist ganglion cyst excisions performed by seven hand surgeons was conducted from 2015 to 2019 at Penn State Hershey Medical Center. Preoperative and intraoperative diagnoses, pathologic diagnosis, and pathology cost were assessed., Results: A total of 407 patients underwent ganglion cyst excision, with 318 (78.1%) specimens sent for pathologic review. Of the 318, 317 (99.6%) specimens were concordant with the preoperative or intraoperative diagnosis of ganglion cyst. One specimen (0.3%) resulted as a benign cystic vascular malformation. The charge per specimen was $258, totaling $81,786 spent confirming benign pathology that was clinically correctly diagnosed by the operating surgeon in 99.6% of cases., Conclusions: Routine pathologic analysis is not indicated in cases in which surgeons have a high clinical suspicion for ganglion cyst based on preoperative and intraoperative findings. Pathologic review should be reserved for cases with atypical presentations or intraoperative findings., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Objectives: This study aims to evaluate the distribution and prevalence of pediatric hand tumors and tumor-like lesions according to age and gender., Patients and Methods: We retrospectively examined the details of hospital records of 646 patients who were operated for hand mass between January 2009 and January 2019 and whose pathological diagnosis was established in the same hospital. A total of 54 patients (18 males, 36 females; mean age 12.07 years; range, 3 month to 17 years) under 18 years of age who had been operated for the wrist or hand mass were included in the study., Results: Out of 54 tumors, 53 were benign (98%) and one was malignant (2%). There were 42 soft tissue tumors (78%) and 12 bone tumors (22%). The most common soft tissue mass was ganglion cyst (n=12). Six out of 12 ganglion cysts were on the dorsal side of hand or wrist and six were on the volar side. The distribution of the tumors according to gender was not statistically significant (p=0.73). We had two recurrences: one patient with giant cell tumor of the tendon sheath and one with palmar fibromatosis., Conclusion: Pediatric hand/wrist masses are mostly benign tumorous conditions. The location of the pathologies may be different from the adults. Diagnosis of the tumor should be established carefully clinically and radiologically while malignant tumors should be kept in mind by both pediatricians and orthopedic surgeons.

Superficial radial intraneural ganglion cysts are rare. Only nine previous cases have been described. We provide two examples with a wrist joint connection and review the literature to provide further support for the unifying articular (synovial) theory for the pathogenesis and treatment of intraneural ganglia.

Objective: The presence of findings at wrist MRI that may mimic disease is a diagnostic problem. The purpose of this study is to examine the occurrence of bone marrow changes resembling edema, joint fluid, and ganglion cysts over time, in a cohort of healthy children., Materials and Methods: Seventy-four of 89 healthy children included in a study of normal MRI findings of the wrists were reexamined after a period of 4 years, using the same 1.5-T MRI technique-namely, a coronal T1-weighted and a T2-weighted fat-saturated sequence. A history of handedness, diseases, and sports activity was noted., Results: Bone marrow edema or edemalike changes were seen in 29 of 74 (39.2%) wrists in 2013 as compared with 35 of 72 (48.6%) wrists in 2009 (p = 0.153), all in different locations. Changes were found in central parts of the bone, on both sides of a joint, or near bony depressions. Fifty percent of all subjects had at least one fluid pocket greater than or equal to 2 mm. The location was unchanged in 47% of the joints. In 24% of the individuals, at least one ganglion cyst was seen. Six ganglion cysts present on the first scan were not seen on the follow-up scan, and 11 new ganglion cysts had appeared., Conclusion: Awareness of normal MRI appearances of the growing skeleton is crucial when interpreting MRI of children, and such findings must not be interpreted as pathologic abnormalities.

Background: The majority of published literature on ganglion cysts in children has been from a surgical perspective, with no dedicated radiologic study yet performed., Objective: Our aim was to assess the magnetic resonance (MR) imaging appearance of ganglion cysts in a series of paediatric MR wrist examinations., Materials and Methods: Ninety-seven consecutive paediatric MR wrist examinations were retrospectively reviewed for the presence of ganglion cysts. Only those studies with wrist ganglia were included. Cysts were assessed for location, size, internal characteristics and secondary effect(s)., Results: Forty-one ganglion cysts (2-32 mm in size) were seen in 35/97 (36%) patients (24 female, 11 male), mean age: 13 years 11 months (range: 6 years 3 months-18 years). The majority were palmar (63.4%) with the remainder dorsal. Of the cysts, 43.9% were related to a wrist ligament(s), 36.6% to a joint and 17.1% to the triangular fibrocartilage complex. Of the patients, 91.4% had wrist symptoms: pain (n=29, 82.9%), swelling (n=7, 20%) and/or palpable mass (n=4, 11.4%); 71.4% patients had significant additional wrist abnormalities., Conclusion: Ganglion cysts were frequently found in children referred for wrist MRI.

Ganglion cysts, soft-tissue masses that commonly occur about the wrist, are often excised without imaging or biopsy. In this article, we report a series of incompletely excised soft-tissue sarcomas about the wrist and offer an algorithm for their evaluation. We describe a series of 4 consecutive patients who each presented after incomplete resection of a soft-tissue sarcoma mistakenly diagnosed as a ganglion cyst. We also retrospectively review the cases of 7 patients with incompletely excised sarcomas of the wrist. Three of the 4 patients with sarcomas mistaken for ganglion cysts did not have prior magnetic resonance imaging (MRI), 3 of the 4 did not have an attempted aspiration, and all 4 did not have transillumination. Common atypical characteristics included ulna-based lesions (3/4), symptoms for less than 6 months (3/4), and no appreciable fluctuation in size (3/4). Functional outcomes for all patients were poor because of multiple surgical procedures, re-excisions requiring flaps, and need for additional adjuvant therapies. Dorsal wrist masses with atypical characteristics should be approached with caution. Transillumination and aspiration are 2 accessible, cost-efficient methods for evaluating these masses. If either test is abnormal, an MRI should be performed.

Purpose: Wrist ganglions are the most common soft tissue tumors of the hand and wrist and can occur at any age. Their etiology remains controversial. A high prevalence of associated intrinsic ligamentous lesions has been described. We hypothesized that painful wrist ganglions are an indicator of an underlying joint abnormality, particularly of lesions of the triangular fibrocartilage complex (TFCC). The aim of our study was to prospectively determine the prevalence of associated TFCC lesions in patients with painful wrist ganglions., Methods: Forty-six patients (35 women, 11 men; mean age, 36 ± 11 y; range, 18-57 y) with painful wrist ganglions (20 radiopalmar and 26 dorsal) had surgery from January 2008 to June 2010. There were 18 primary and 28 recurrent ganglions. Clinical examinations, pain score evaluations, disabilities in daily life evaluations, plain radiographs, and magnetic resonance imaging were obtained before arthroscopic resection. Concomitant intrinsic lesions of the wrist were assessed with magnetic resonance imaging and re-evaluated by arthroscopy., Results: All ganglions were successfully resected. Overall, arthroscopy identified 22 TFCC lesions (48%) and 2 intracarpal ligament lesions. The TFCC perforations were more commonly associated with radiopalmar ganglions with a positive ulnocarpal stress test result and with recurrent radiopalmar ganglions. At 1-year follow-up, all patients were meaningfully improved in terms of pain and disabilities in daily life., Conclusions: Arthroscopy allows for the simultaneous treatment of ganglions and other pathologies. Therefore, arthroscopy should be contemplated as the primary treatment option for patients with painful ganglions of the wrist if they are in a radiopalmar location with a positive ulnocarpal stress test and for patients with recurrent radiopalmar ganglions, which are also highly associated with TFCC abnormalities., Type of Study/level of Evidence: Therapeutic IV., (Copyright © 2012 American Society for Surgery of the Hand.

Objectives: The aim of this study was to assess the results of surgical treatment of patients who had complaints of chronic wrist pain and were diagnosed as having an occult dorsal scapholunate interosseous ganglion, despite the presence of a normal x-ray and absence of trauma., Methods: Thirteen wrists of 12 patients (2 males, 10 females; mean age 28 years; range 21 to 41 years) were treated with surgical excision for ganglia originating from the dorsal scapholunate interosseous ligament. Involvement was on the right side in six patients, and on the left in five patients, with one patient having bilateral involvement. None of the patients had a history of trauma, except two with a history of fall. All the patients had complaints of wrist pain that occurred during work and subsided at rest. The mean duration of wrist pain was 23 months (range 6 to 60 months). All the patients received conservative treatment previously with wrist splints and non-steroidal anti-inflammatory drugs. Finger extension test was positive and magnetic resonance imaging of the wrist showed ganglion in all the patients. Functional results were evaluated by the Mayo Clinic wrist pain assessment scores after a mean follow-up of 35 months (range 25 to 49 months)., Results: Complaints of wrist pain improved dramatically in all the patients. Scores of the Mayo Clinic wrist pain assessment were excellent in seven patients (53.9%), good in five patients (38.5%), and moderate in one patient (7.7%). All the patients returned to work without any limitation of wrist movements. No recurrences were seen during the follow-up period., Conclusion: Occult ganglia originating from the scapholunate ligament should be remembered in patients with dorsal scapholunate joint tenderness and pain unresponsive to conservative treatment and with a positive finger extension test.

Ganglion cysts of the hand and wrist occur most frequently during the second through fourth decade and women are more frequently affected than men. Ganglion cysts may arise in any location in the hand and wrist but are usually adjacent to joins or tendons and sometimes bones. Patients often present with a history of an asymptomatic mass and many patients seek the advice of a physician because of the cosmetic appearance of the cyst. Observation is acceptable in most instances. Indication for operative treatment includes pain, interference with activity, nerve compression and ulceration of the mucous cysts.
