Endoscopic Release of Master Knot of Henry

Introduction: Internal snapping hip syndrome (ISHS) is caused by the iliopsoas tendon snapping over either the iliopectineal ridge or the anterior femoral head. Excellent results are achieved only with activity modification, rest, and stretching the iliopsoas muscle. The literature favors iliopsoas tendon release if conservative therapy fails. There is little evidence about the gold standard of this condition. Objective: Describe clinical results, complicactions and recurrence rate of arthroscopic treatment of ISHS. Methods: We included all patients who failed conservative treatment and were treated with arthroscopy for ISHS between March 2012 and March 2018. Patients with less than 2 years of follow up and previous surgery on the hip were excluded. We performed Ilizariturri´s technique with a transcapsular endoscopic release in central compartment. We registered modified Harris hip score (MHHS), Hip outcome score activity of daily living (EHOSDL), patients satisfaction, recurrence rate and complications. Results: Eight patients were included. Average follow up was 36 months (range 24-60 months). MMHS improved from preoperative average score of 70 (range 62-72) to postoperative average of 93 (range 92 to 96). Average EHOSDL improvement was 30% (from 55% preoperative to 85% postoperative). All patients had excellent results. Average patient satisfaction was 8 (range 7-9). We had no recurrence or complications. Conclusion: Arthroscopic treatment of ISHS allowed us to obtain very good clinical results with no complications or recurrences with a minimum 2 years follow up.

Tunnel Syndrome

Carpal tunnel syndrome is conventionally treated by open and endoscopic release surgeries in which transecting the transverse carpal ligament (TCL) relieves mechanical insults around the median nerve. The TCL release surgeries yield an increase in the tunnel cross-sectional area particularly within the volar aspect of the tunnel, the arch area, where the median nerve is located. As a result of increased arch area, post-operative follow-up studies using MRI confirmed a significant volar migration of the median nerve [1]. However, transecting the TCL compromises critical biomechanical roles of the carpal tunnel [2], and therefore, it is imperative to investigate an alternative method for treating carpal tunnel syndrome patients while preserving the TCL. Li et al. suggested that increasing the TCL length and narrowing the carpal arch width (CAW) as potential alternatives for increasing the arch area [3]. However, the data from their application of palmarly directed forces to the TCL from inside of the tunnel showed that the TCL length remained relatively constant while the carpal bones were mobilized to increase the arch area [3]. The purpose of this study was to investigate the relationship between CAW narrowing and the TCL-formed arch area by experimental and geometrical modeling.
