Two-Stage Revision Protocol in Multidrug Resistant Periprosthetic Infection Following Total Hip Arthroplasty Using a Long Interval Between Stages

We retrospectively reviewed the medical records of 31 patients with periprosthetic hip infections attempting to evaluate the outcome of a two-stage revision protocol characterized by prolonged interim period (mean = 9.2 months, range 8-12 months) prior to the final re-implantation. In 3 cases (9.6%) the 1st stage was repeated after a mean period of 12.3 weeks due to relapse of infection. Five spacer dislocations occurred, not affecting the final clinical outcome after reimplantation, as evaluated by the Harris Hip Score. No protrusions or additional acetabular bone loss was noticed. Our proposed protocol is a simple, safe, efficient and reproducible treatment approach that may be successfully utilized predominantly when dealing with multidrug resistant pathogens.

Differences in Outcomes According to the Primary Treatment Options Chosen by Patients With Carpal Tunnel Syndrome and negative neurophysiological studies: Conservative Versus Operative Treatment. Do we need neurophysiological studies?

The purpose of this study is to compare the outcomes of conservative versus operative treatment in patients with a positive history and clinical findings forCarpal Tunnel Syndrome (CTS) and negative nerve conduction studies (NCS). A cohort of 126 consecutive patients (34 males, 92 females) with mean age of 48 years old, positive history and clinical findings for CTS but negative NCS was studied. The mean duration of symptoms was 9.1 months.  Group I (94 patients) underwent conservative treatment, whereas group II (32 patients) underwent mini open carpal tunnel release. The clinical diagnosis was based on the Harrington criteria. Patients were evaluated at baseline and at 12-months follow-up using the Boston Carpal Tunnel Questionnaire (BCTQ) and the Disabilities of the Arm, Shoulder and Hand (DASH) instrument. At baseline, group I had lower BCTQ and DASH scores, compared to the respective scores of group II. At the final 12-month follow-up, patients in group I had higher BTCQ scores. Post-treatment, group II showed significant improvement of BTCQ score (p< 0.001) and DASH score (p<0.05).The additional value of NCS is limited  when there is strong clinical suspicion
