    Abstract Introduction Propionibacterium acnes infection after shoulder arthroplasty remains a source of morbidity. Determining practices amongst shoulder surgeons is the first step in developing infection-prevention best-practices. Methods A survey was sent to a shoulder fellowship alumni group to determine their arthroplasty infection prevention methods Results 74% completed the survey. Cefazolin (90%), vancomycin (50%) and clindamycin (18%) were the most commonly used antibiotics, 61% utilized more than one antibiotic. Most (76%) reported using an experience-based protocol learned during residency/fellowship. Discussion and conclusion There are no clear standards for prevention of Propionibacterium acnes infections in shoulder arthroplasty. There is a general non-scientific approach to the prevention of shoulder arthroplasty infection.

    Abstract Gait analysis using external skin markers provides scope for the study of kinematic and kinetic parameters shown on different total knee arthroplasties (TKA). Thus an appropriate methodology is of great importance for the collection and correlation of valid data. Calibration of equipment is of great importance before measurements, to assure accuracy. Force plates should be calibrated to 1080 Hz and optoelectronic cameras should use 120 Hz frequency, because of the nature of gait activity. Davis model which accurately defines the position of the markers is widely accepted and cited, for the gait analysis of TKA’s. To ensure the reproducibility of the measurement, a static trial at the anatomical position must be captured. Following, all acquisitions of dynamic data must be checked for consistency in walking speed, and abnormal gait style because of fatigue or distraction. To establish the repeatability of the measurement, this procedure must be repeated at a pre-defined number of 3–5 gait cycles. Anthropometric measurements should be combined with three-dimensional marker data from the static trial to provide positions of the joint’s center and define anatomical axes of total knee arthroplasty. Kinetic data should be normalized to bodyweight (BW) and percentage of BW and height depending on the study. External moments should also be calculated by using inverse dynamics and amplitude-normalized to body mass (Nm/kg). Gait analysis using external skin markers provides scope for the study of biomechanical parameters shown on different TKAs. Thus a standard gait analysis methodology when measuring TKA biomechanical parameters is necessary for the collection and correlation of accurate, adequate, valid and reproducible data. Further research should be done to clarify if the development of a specific kinematic model is appropriate for a more accurate definition of total knee implant joint center in measurements concerning 3D gait analysis.

    Abstract Objective Pediatric femoral shaft fractures are more commonly treated with intramedullary titanium elastic nail system (TENS). Adhering to the principles, most studies had supported excellent results with this instrumentation and attributed the variation in age, weight, immobilization protocols, technical factors like fracture pattern, reduction and complications as reasons to poor outcomes in their individual studies. Hence, we wanted to identify the potential demographic and perioperative parameters that could affect the final outcomes in this cohort. Methods A prospective (level III) study done in a single center between November 2013 and January 2017 on isolated closed femoral shaft fractures in patients of age between 6 and 15 years managed with TENS. The demographic and perioperative parameters were recorded. The patients were followed up regularly with plain radiographs. The final outcomes were computed at end of one year and recorded as poor, satisfactory and excellent as defined by Flynn criteria. Results Among the thirty patients included, mean age was 8.2 years. 80% of the patients weighing over 40 kg had satisfactory to poor outcomes. (p = 0.005). 45% of patients with proximal and distal level fractures that were long oblique spiral or comminuted types had satisfactory outcomes; however it was not statistically significant. The mean delay to surgical fixation was 5.87 days, surgical time was between 45 and 150 min and open reduction was required in about 17 cases (57%). Patients with immobilization beyond 6 weeks had satisfactory outcomes (p = 0.001). We had 5 patients with minor complications (4 bursitis and 3 superficial infections) and one major complication (chronic osteomyelitis and deep venous thrombosis) leading to satisfactory and poor outcomes respectively. Significant osseous union was noted between 6 and 11 months with 97% of patients attaining union within 9 months. Conclusions Intramedullary TENS is an excellent modality to treat femoral shaft fractures in patients of school going age. However, factors like weight of the patient >40 kg, immobilization beyond 6 weeks, minor and major complications in the perioperative period could pose risks for poor to satisfactory outcomes and should be anticipated and explained accordingly.

    Abstract Introduction The aim of this study was to calculate the wear rate of highly cross-linked polyethylene (HXLPE) and investigate long-term clinical and radiographic outcomes related to two femoral stem designs, the distal-cylindrical (DC) and distal-taper (DT) stems. Materials and methods Outcomes for the DC and DT stems were evaluated in 110 patients, who underwent total hip arthroplasty using an HXLPE socket, over a 5-year follow-up period. There were 56 hips (53 patients) in the DC group and 60 hips (57 patients) in the DT group. Clinical outcomes were measured using the Japanese Orthopaedic Association (JOA) score and radiographic changes. Polyethylene wear rate was calculated using a computer software. Results The mean follow-up period was 135.7 and 124.0 months for the DC and DT groups, respectively. Both stem designs improved hip function. On radiographic assessment, osteolysis around the tip of the stem was more frequent in the DC than in the DT group. Three cases of aseptic loosening of the stem were identified in the DC group, and no cases were identified in the DT group. The 10-year stem survival, using aseptic loosening as the primary endpoint, was 94.1% and 100% for the DC and DT groups, respectively (p = 0.06). The polyethylene wear rate was comparable for both stem groups. Conclusion Better clinical outcomes were obtained with the DT stem than with the DC stem regardless of the equivalent polyethylene wear rate for the two designs. The DC shape of the stem may increase the risk of aseptic loosening.

    Abstract We reported the longitudinal changes in serum chromium levels over a minimum of 7 years postoperatively in five men and 25 women with a mean age of 60.3 years after primary unilateral total hip arthroplasty with a Metasul metal-on-metal articulation. The serum chromium ion level showed little variation (0.6–1.2 μg/L) from 2 to 12 years postoperatively in 16/30 patients after unilateral primary Metasul metal-on-metal total hip arthroplasty. On the other hand, the serum chromium level stayed high or showed gradual elevation in 8/30 patients, even though they had well-fixed and well-functioning prostheses.

    Abstract The aim of this study is to underline the necessity of a better knowledge of pedicles anatomy in order to improve surgical treatment of spine disorders such us low back pain, spinal fractures and scholiosis. A classification of pedicles lateral tilt which could help surgeons before the application of screws during transpedicular fixation is reported. Anatomical differences in the orientiation of the pedicles of L5 and L4 have been found. For each patient that met the inclusion criteria underwent: Radiography of the lumbo-sacral region, CT examination, MRI acquisition. Patients were divided into three categories thanks to 3D direct volume rendering of CT scan. Subjects belonged to W-Type, V-Type and U-type depending on their morphometric features. The subdivision was further implemented with measurements of the distance between pedicles and adjacent nervous structures. Concerning L5, W-Type (WT) exhibited a lateral tilt of L5 larger than 36°, V-Type exhibited a lateral tilt of L5 from 30° to 36°, U-type exhibited a lateral tilt of L5 smaller than 30°. Concerning L4, WT exhibited a lateral tilt of 28.4°, VT exhibited a lateral tilt of of 25.1, UT exhibited a lateral tilt of 22.2°; we assume that the degree of lateralization of L4 depends on the one of L5. The way the screw is applied during surgical treatment is clinically relevant, thus our classification may be very useful in order to decrease surgical risk and improve conditions of patients after surgical treatment.

    초록

    Abstract Purpose There is no doubt that the best outcome achieved in Cauda equina syndrome (CES) involves surgical decompression. The controversy regarding outcome lies with timing of surgery. This study reports outcomes on a large population based series. Timing of surgery, Cauda Equina syndrome classification based on British Association of Spine Surgeons (BASS) guidelines and co-morbid illness will be assessed to evaluate influence on outcome. Materials and methods A retrospective review of all patients surgically decompressed for CES between 01/01/2008 to 01/08/2014 was conducted. Patients with ongoing symptoms were followed up for a minimum of 2 years. Cauda Equina Syndrome (CES) was classified according to the BASS criteria: CES suspicious (CESS), incomplete (CESI) and painless urinary retention (CESR). Time and symptom resolution were assessed. Results A total of 136 patients were treated for CES; 69 CESR, 22 CESI and 45 CESS. There was no statistical difference in age, sex, smoking status and alcohol status with regards to timing of surgery. No correlation between increasing co-morbidity score and poor outcome was demonstrated in any subgroup All CESR/I patients demonstrated some improvement in bowel and bladder dysfunction post-operatively. No significant difference in improved autonomic dysfunction was demonstrated in relation to timing of surgery. CES subclassification may predict outcome of non-autonomic symptoms. Statistically better outcomes were found in CESS groups with regards to post-operative lower back pain (P 0.049) and saddle paraesthesia (P 0.02). Conclusion Surgical Decompression for CES is an effective treatment that significantly improves patient symptoms including bowel and bladder dysfunction Early surgical decompression

    Abstract Purpose To identify early determinants of clinical outcome after knee cartilage repair. Methods 205 patients were evaluated before surgery and at median 14-years follow-up. Results Baseline factors predicting a good outcome were: single lesion; normal appearing cartilage surrounding the lesion; high baseline Lysholm score; short duration of symptoms; non-involvement of the patella-femoral joint; young age; and small defect. Factors predicting a poor outcome were: multiple lesions; low baseline Lysholm score; degenerative cartilage surrounding the lesion; long symptom duration; meniscal lesion; and large defect. Conclusions The choice of surgical method seem to be less important than other patients-specific predictors. Level of evidence Case series, Level IV.
