Background: Giant cell tumor of the tendon sheath is the most common form of giant cell tumors and is the second most common soft tissue tumor of the hand region after ganglion cyst. Magnetic resonance imaging is the diagnostic tool of choice for both diagnosis and treatment planning. The current standard treatment of choice is simple excision. The main concern about the treatment is related to the high recurrence rates. Besides incomplete excision, there is no consensus concerning the effect of other risk factors on recurrence. The literature lacks detailed reports on surgical excision of these tumors with a standardized surgical treatment and an appropriate patient follow up. The aim of this study was to investigate the recurrence rate and the associated recurrence risk factors for giant cell tumor of tendon sheath of the hand following a standardized treatment. Methods: The records of patients treated for giant cell tumor of tendon sheath of the hand treated by the same hand surgeon were evaluated retrospectively. The features obtained from preoperative magnetic resonance imaging, final physical examination, patients' age and sex, anatomical site of the tumor, relationship of the tumor with bone, joint or neurovascular structures, bone invasion, recurrence after surgery and complications like skin necrosis, digital neuropathy or limitation in range of motion were documented. Chi-square test was used to compare categorical variables. Results: Fifty patient were included in the study. The average follow-up time was 84 months. Three recurrences (6%) were recorded. The only significant risk factor for the recurrence was tumor adjacency to the interphalangeal joints of the fingers other than thumb. No major or minor complications were encountered in the postoperative period. Conclusion: With adequate surgical exposure and meticulous dissection provided by the magnification loupes, we were able demonstrate one of the lowest recurrence rates in the literature. Well-designed studies combining the recurrence rates of several hand surgery centers implementing a standardized treatment are needed to better demonstrate the associated risk factors for recurrence.
Proper selection of distal fusion level is important in order to prevent DJK after SK surgery. According to this study, it is not necessary to extend the fusion down to the SSV. Fusion to FLV is sufficient and saves a level.
Introduction: Meniscal cysts very often cause meniscal tears and especially when it is peripheral, some of the healthy parts of meniscus might be needlessly sacrificed. In particular conditions, extraarticular approaches might save some menisci. In the present study, we evaluated the conditions which required using the extraarticular approach in addition to the arthroscopic procedure, to maximally preserve the meniscus.
Methods: Eight patients with perimeniscal cysts were evaluated retrospectively. One cyst was localized within the medial meniscus and seven in the lateral meniscus. The mean age was 36.13 (range; 19–63) years, mean follow-up time, 27.3 (range; 12–47) months. Patients were evaluated by using a Visual Analogue Score (VAS) to measure pain relief and “Lysholm score” to measure functional improvement. In all patients except one, in which the cystic cavity was connected with the joint at the periphery of the meniscus, the cyst was drained from the intraarticular opening. When the cyst was too large (three cases) and in one case where a large amount of meniscus was preserved for reasons mentioned above, additional extraarticular drainage was carried out.
Results: The mean preoperative and postoperative VAS were 6 (range; 2–8) and 1.55 (range; 0–3) (p = 0.00058) and Lysholm scores were 64.75 (range; 48–86) and 93.11 (range; 80–100) (p = 0.0014), respectively.
Discussion: In cysts, which have very limited or no connection with the joint on the most peripheral region of the meniscus and/or are larger than the meniscus height, extraarticular drainage of the cyst might produce unnecessary meniscal loss and function. In the extraarticular drainage, scrapping the walls of the cyst, while inspecting with an arthroscope, reduces recurrence of the cyst.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
