IntroductionPosterolateral-approached total hip arthroplasty (PLTHA) is followed by moderate to severe postoperative pain. Suprainguinal fascia iliaca compartment block (SFICB) has been proposed as a promising analgesia technique.MethodsData from 86 patients scheduled for PLTHA with spinal anesthesia were analyzed in this prospective randomized controlled trial. Patients were randomly divided into two groups of 43 patients each. As opposed to the control group (group C), ropivacaine group (group R) received additional SFICB using 40 mL of 0.375% ropivacaine. As primary endpoint, blind observers noted total morphine consumption at postoperative 48 hours. Secondary endpoints were pain at rest and mobilization on 0–10 Numeric Rating Scale (rest and dynamic NRS) at fixed time points (1 hour and 6 hours after surgery, and at day 1 and day 2 at 8:00, 13:00 and 18:00 hours), walking performance at day 1 and day 2; postoperative complications including morphine-related side effects or orthostatic intolerance symptoms such as dizziness, nausea, blurred vision or vasovagal syncope.ResultsA 48-hour morphine consumption (mg; median (IQR)) was significantly lower in group R than in group C (11 (8.5–15.5)) vs 26 (21–33.5), p<0001), as well as incidence of morphine-related side effects such as nausea at day 1 (p=0.04) and day 2 (p<0.01). Rest and dynamic NRS were globally significantly lower in group R than in group C (p<0.01). Group R showed less orthostatic intolerance at day 1 (p<0.001) and day 2 (p<0.01) and better functional walking performance at day 1 (<0.001) and day 2 (<0.001).DiscussionIn PLTHA, SFICB provides opioid sparing, improved postoperative pain control, and enhanced functional recovery.Trial registration numberNCT04574479.

BackgroundSevere obstructive sleep apnea (sOSA) and preoperative hypoxemia are risk factors of postoperative complications. Patients exhibiting the combination of both factors are probably at higher perioperative risk. Four scores (STOP-Bang, P-SAP, OSA50, and DES-OSA) are currently used to detect OSA patients preoperatively. This study compared their ability to specifically detect hypoxemic sOSA patients.MethodsOne hundred and fifty-nine patients scheduled for an overnight polysomnography (PSG) were prospectively enrolled. The ability of the four scores to predict the occurrence of hypoxemic episodes in sOSA patients was compared using sensitivity (Se), specificity (Sp), Youden Index, Cohen kappa coefficient, and the area under ROC curve (AUROC) analyses.ResultsOSA50 elicited the highest Se [95% CI] at detecting hypoxemic sOSA patients (1 [0.89–1]) and was significantly more sensitive than STOP-Bang in that respect. DES-OSA was significantly more specific (0.58 [0.49–0.66]) than the three other scores. The Youden Index of DES-OSA (1.45 [1.33–1.58]) was significantly higher than those of STOP-Bang, P-SAP, and OSA50. The AUROC of DES-OSA (0.8 [0.71–0.89]) was significantly the largest. The highest Kappa value was obtained for DES-OSA (0.33 [0.21–0.45]) and was significantly higher than those of STOP-Bang, and OSA50.ConclusionsIn our population, DES-OSA appears to be more effective than the three other scores to specifically detect hypoxemic sOSA patients. However prospective studies are needed to confirm these findings in a perioperative setting.Clinical trial registrationClinicalTrials.gov: NCT02050685.

A 78-year-old female presented with dislocation of a dual mobility hip prosthesis. On standard radiographs after closed reduction, the hip prosthesis appeared to be properly reduced, but clinically the hip was unstable. A Computed Tomography showed a round foreign body, that was in fact a dislocation of the intra-prosthetic implant. This was confirmed intra-operatively during revision surgery. Intra-prosthetic dislocation is a specific complication of dual mobility system. Classically, it's a late complication, linked to the wear of retention area of the polyethylene insert. In this case report we describe an unusual reason of intra-prosthetic dislocation caused by a reduction maneuver of a dislocated dual mobility total hip prosthesis, which to our knowledge has never been documented with Computed Tomography imagery and intra operative pictures. The aim of this article is to analyse the advantages and complications of this implant and to establish recommendations. Dealing with an intra-prosthetic dislocation of a dual mobility hip prosthesis, we recommend attempting a reduction under general anesthesia to avoid mechanical complications. In case of persistent instability after reduction, we recommend performing a Computed Tomography scan.

Rationale:Heptadactylia is a rare congenital disorder from the polydactyly family. Polydactyly is generally classified into 3 major groups: preaxial (medial ray), postaxial (lateral ray), and central polydactyly. Most common cases are related to preaxial or postaxial polydactyly. The rarity of central polydactyly can be explained in 3 ways. First, central polydactyly with duplication appearing on metatarsal is pretty uncommon. Second, the duplication appears isolated on the foot. Polydactyly is mostly associated with other physical defects or others duplications. Last, the duplication of the digital rays does not appear once but twice concerning all the digital rays and makes 7 functional toes appear. We describe this malformation with supporting iconography and radiography as well as its surgical management and functional results.Patient concerns:We analyzed an original case of isolated heptadactylia on the foot of a 14-month-old girl. The supernumerary toes made it impossible for the child to wear standard shoes and her parents were worried about this problem.Diagnoses:Clinical foot examination and radiographs revealed the presence of 7 complete rays. Every toe was composed of phalanx and metatarsal ray. There was no other congenital deformity.Interventions:Decision was made to resect the second and third rays (the two most misaligned toes in our consideration). The first stage of surgery was the ray resection and the second stage was the reconstruction of the intermetatarsal ligament to achieve a good functional and cosmetic results.Outcomes:After wound healing, the child was able to walk alone while wearing normal shoes.Lessons:We demonstrated that treatment of foot polydactyly requires careful preoperative assessment, including radiographs and photography. A good clinical evaluation of the medial polydactyly improves type-specific recognition which may enhance the accuracy of surgical treatment. Polydactyly is frequently associated with other malformations. We recommend performing a general clinical examination to exclude concomitant malformations. We recommend surgical treatment around the onset of walking.
