Narrow Results

Upper extremity adventitial cystic disease is rare, but the characteristic findings of this lesion should be known to the hand surgeon and used to guide treatment. We present a case of a young adult male who developed a painless mass in his distal forearm. Diagnostic imaging workup revealed a cystic mass that extended within and encased the radial artery. Both MRI and direct intraoperative visualization confirmed the presence of a stalk connecting the intra-mural radial artery mass to the radiocarpal joint. The mass and stalk were excised en bloc with fenestration of the volar capsule to prevent recurrence. This case demonstrates a less common example of upper extremity adventitial cystic disease and supports the articular theory of origin of these lesions. When surgical excision is performed, an attempt should be made to identify and excise the articular stalk in an effort to minimize risk of recurrence.

Background: Ganglion cysts are common soft tissue masses of the hand and wrist. It is unclear why some patients pursue surgical excision and others do not. The objective of this study is to compare Patient-Reported Outcomes Measurement Information Systems (PROMIS) scores between patients with ganglion cysts undergoing surgical versus non-surgical treatment.

Methods: Patients presenting to a tertiary, academic hand clinic diagnosed with a wrist ganglion cyst, based on clinical exam, were identified. PROMIS Physical Function (PF), Pain Interference (PI), and Depression scores at the time of diagnosis were reviewed. Data were then stratified according to surgical or non-surgical intervention, with subgroup analysis of dorsal versus volar ganglions and patients that chose to trial cyst aspiration. All results were compared utilizing the appropriate statistical methods.

Results: Of 757 ganglion cyst patients, 264 underwent surgical excision and 493 were treated non-surgically. No difference was noted in PROMIS PF or Depression scores. However, the surgical cohort reported significantly increased preoperative PI scores (Table 2). A higher percentage of patients treated non-surgically received an aspiration attempt compared to those who ultimately received surgery (Table 3). Finally, patients with volar ganglion cysts had significantly increased PI and depression scores, as well as lower PF scores (Table 4).

Conclusions: Presenting PROMIS PI may indicate an increased tendency to pursue surgical treatments and aid in the identification of ganglion cyst patients who are more likely to pursue surgical excision. Further research should focus on correlating absolute differences in PROMIS values with clinical significance.

Background: This study aimed to evaluate our preliminary results and experience with the arthroscopic dorsal ligamentocapsulodesis in managing occult dorsal wrist ganglion cysts (ODGCs) associated with scapholunate (SL) instability.

Methods: All patients who underwent arthroscopic dorsal ligamentocapsulodesis due to an ODGC with concomitant SL ligament tear were retrospectively reviewed. In addition to demographic data and length of follow-up, outcomes data that included range of motion, grip strength, modified Mayo wrist score (MMWS), complications and radiographs were collected.

Results: The study included 18 patients (18 wrists; 10 female and 8 male). The mean age was 32 years (range: 19–48) and the mean follow-up was 34 months (range: 24–48). The mean preoperative extension deficit decreased from 5.5° (range: 0°–20°) to 2.7° (range: 0°–15°) at the final follow-up (p = 0.004). The mean preoperative flexion deficits decreased from 4.4° (range: 0°–15°) to 2.2° (range: 0°–10°) postoperatively (p = 0.003). The mean hand grip strength significantly increased from 27.7 kg (range: 22–36) to 38.3 kg (range: 31–46) at the final follow-up assessment (p < 0.001). The mean MMWS improved from 46 (range: 25–65) pre-operatively to 91 (range: 70–100) at the final follow-up (p = 0.0002). No major intra- or postoperative complications were observed.

Conclusions: SL instability may have an important role in the aetiology of ODGCs, and arthroscopic dorsal ligamentocapsulodesis can provide pain relief and functional improvement without recurrence at the short- to mid-term follow-up in the treatment of ODGCs.

Level of Evidence: Level IV (Therapeutic)

Intraneural ganglia are rare, benign cysts that form within the epineurium of the affected nerve. Patients present with features of compressive neuropathy, including numbness. We report a 74-year-old male patient with pain and numbness on his right thumb of 1-year duration. Magnetic resonance imaging revealed a cystic lesion with a possible scaphotrapezium-trapezoid joint connection. The articular branch was not identified during the surgery and decompression with excision of the cyst wall was done. A recurrence of the mass was noted 3 years later, but the patient was asymptomatic and no additional intervention was done. Decompression alone can relieve the symptoms of an intraneural ganglion, but excision of the articular branch may be essential in preventing its recurrence.
