RESUMO
BACKGROUND: To present the outcomes of arthroscopic electrothermal shrinkage for partial scapholunate (SL) ligament tears, isolated or with associated triangular fibrocartilage complex (TFCC) injuries. METHODS: A prospective study of 20 patients with symptomatic instability of SL ligament (14 of them also with TFCC wrist injuries) treated with arthroscopic electrothermal shrinkage was conducted using a monopolar radiofrequency probe. No patient showed radiologic signs of static dissociation (mean SL interval 2.2 ± 0.6 mm; mean SL angle 41.4° ± 6.7°) before surgery. All patients underwent follow-up at our clinic regularly for an average of 50.6 months (range 29-80 months). RESULTS: The modified Mayo wrist score improved from a mean of 59 ± 17.1 points preoperatively to 88.3 ± 16.2 points at the final follow-up. At the final clinical examination, a painful Watson scaphoid shift test was found in 3 patients (15%). The mean flexion-extension arc was unchanged (132° ± 19°), and mean grip strength improved 12 kg. No patient showed radiologic signs of arthritis or instability after surgery (mean SL interval 1.9 ± 0.7 mm; mean SL angle 42.7° ± 7.3°). Of the 14 patients with combined TFCC injuries, 3 patients continued complaining of ulnar-sided point tenderness. At the end of the follow-up, 80% of the subjects were satisfied or very satisfied. CONCLUSIONS: SL ligament and TFCC electrothermal shrinkage effectively provided pain relief and grip strength increase for most of the patients treated. LEVEL OF EVIDENCE: Level IV.

Small-cell anaplastic carcinoma of the colon is a very infrequent tumour (less than 1% of all colorectal neoplasms). Thirty-two cases have been described in the international literature up to 1992. A case, in a 54 year-old patient who underwent successful resection is presented. The importance of this tumour is due to its great aggressivity, and its great tendency to produce early hematogenous and lymph node metastases. It implies a bad prognosis and a survival of around 0% at one year. Because of these facts, treatment must include, beside surgical resection, an aggressive systemic protocol.
