OBJECTIVE: To review hearing results after implantation of a self-crimping stapes prosthesis. STUDY DESIGN AND SETTING: Analysis of hearing results in patients implanted with a self-crimping stapes prosthesis at two academic hospitals from 2000 to 2004. RESULTS: Seventy-nine ears were divided into short-term and intermediate follow-up groups. The mean postoperative air-bone gap (ABG), preoperative minus postoperative ABG, and preoperative minus postoperative bone conduction values were 5.7, 21.4, and 4.1 dB, respectively, for the short-term group, and 6.3, 22.3, and 4.7dB, respectively, for the intermediate group. The ABG was <10 dB in 88 percent of the short-term group and in 79 percent of the intermediate group. CONCLUSIONS: The self-crimping Nitinol stapes prosthesis provides excellent short-term and intermediate postoperative hearing results, and may overcome the limitations of stapes prostheses requiring manual crimping. SIGNIFICANCE: This paper provides evidence for the use of a self-crimping Nitinol stapes prosthesis, which may simplify hearing restoration surgery for stapes fixation.

Aim: To check the short-term tonometric results of SLT in the treatment of primary glaucoma at the open angle and in charge of ocular hypertonias in Togolese people. Methods: A retrospective study was carried out in an ophthalmology center. The first 130 eyes of 72 patients benefited from the SLT laser procedure. The tonometric controls work object focus on follow-up at 1, 3, and 6 months post laser treatment. Results: 130 eyes of 72 patients were collected. The average age of the patients was 49.74 years (± 17.45) and the ages vary between 10 and 85 years. The average IOP of the laser before the laser (J0) was (24.99 ± 8.41) mm Hg. The mean IOP at the post-laser control at 1 month was (18.79 ± 3.73) mm Hg. The average IOP for the post-laser control at 3 months was (18.44 ± 3.81) mm Hg. The mean IOP at the post-laser control at 6 months was (18.13 ± 3.63) mm Hg. The percentage reduction in intraocular pressure compared to IOP was pretreated from 20.2% to 1 month; 22.1% at 3 months; and 23.3% at 6 months. In 1 month, 49.2% of the eyes we treated showed a reduction in IOP of less than 20% compared to IOP pretreatment. After 3 months and 6 months, it was 55.4% higher. Also, 52.3% have a PIO reduction percentage which is greater than or equal to 20% compared to pre-treatment IOP. Discussion: Selective laser trabeculoplasty, most especially, is interesting in ocular hypertonies. Treatment of over 180 ° allows one patient out of two to have a pressure reduction that is greater than or equal to 20%. Conclusion: The SLT presents a significant advantage for our glaucomatous patients.

A prospective randomized study of femoral stem fixation comparing Boneloc and Simplex cements was carried out. A collarless double-tapered femoral component was used in all cases. The material consisted of 94 patients representing 97 THRs (3 bilateral cases). Their mean age was 76 years (range 58-88). Clinico-radiographic follow-ups were carried out after 3 months, 12 months and 2 to 3 years. The mean follow up time was 2.5 years. Clinically there was no difference between the groups. Radiolucencies at the bone-cement interface and metal-cement interface, cement cracks, and subsidence of the femoral component were compared. No significant differences could be proven between the fixation patterns of the bone cements during this short-term follow-up.

Objective: To evaluate the long-term safety and efficacy of the Clip coupler attached to the stapes head in patients with unilateral congenital aural atresia (CAA). Methods: This single-center retrospective study included 16 Mandarin-speaking patients who had unilateral microtia accompanied by CAA. All patients were divided into two groups: the short-term follow-up group (n = 9) and the long-term follow-up group (n = 7). The floating mass transducer of the Vibrant Soundbridge (VSB) was positioned in the stapes head by the Clip coupler. The safety of the VSB was investigated by comparing preoperative and postoperative bone-conduction (BC) thresholds as well as by complications. The effectiveness was evaluated by functional gain (FG), word recognition score (WRS), speech reception threshold (SRT) and signal-to-noise ratio (SNR). Results: Pre- and post-operative BC thresholds were no different in all patients. And no complications developed. VSB-aided thresholds in the free-field had improved significantly in both short- and long-term follow-up groups. The improvements of WRS were observed in two groups. The monosyllabic VSB-aided WRS in the long-term follow-up group was significantly higher than that in the short-term follow-up group. When speech was from the impaired ear and noise presented to the side of normal ear (SVSBNCL), lower SNRs were found in two groups after VSB implantation. However, there was no statistical difference in aided SNR between the two groups at SVSBNCL status. Conclusions: Our results show that the FMT connected to the stapes head is a secure and useful device for patients with unilateral CHL/MHL, not only in terms of improved hearing thresholds, but also improved speech intelligibility in quiet and noisy environments.

Category: Ankle Arthritis Introduction/Purpose: Problems associated with mid- to long-term total ankle arthroplasty (TAA) include loosening and sinking of the talus implant. These problems arise due to a lack of stability compared with artificial joints such as knees and hips. In Japan, aluminum ceramic talus implants have been developed and are reported to result in good treatment outcomes. Here we investigated and report the treatment outcomes for combined TAA (cTAA), in which TAA is combined with a talus implant during the initial procedure. Methods: We assessed 15 cases involving 16 feet that underwent cTAA for which follow-up was available for at least 6 months. These cases comprised five feet with stage IIIb osteoarthritis and nine feet with stage IV osteoarthritis according to the Takakura classification as well as two feet with talus necrosis. The mean patient age was 73.5 years, and the mean follow-up period was 9.1 months. The talus implant was completely customized for all cases, and TNK Ankle (Kyocera, Japan) tibial components were used. Assessments were performed before and after surgery using the Japanese Society for Surgery of the Foot scale (JSSF scale) for physician-led objective evaluation and the Japanese Orthopaedic Association/Japanese Society for Surgery of the Foot and Self- Administered Foot Evaluation Questionnaire (SAFE-Q) subscales for patient-reported subjective evaluation. The validity and reliability of the JSSF scale and SAFE-Q have been verified by metering psychological verification. Scores were compared using paired t-tests. Results: The mean JSSF score improved significantly from 46.7 points preoperatively to 85.3 points postoperatively. For the SAFE-Q, pain and pain-related scores improved significantly from 40.5 points preoperatively to 75.8 points postoperatively (p < 0.001), physical function and daily lifestyle status improved significantly from 41.1 points preoperatively to 72.9 points postoperatively (p < 0.001), social lifestyle function improved significantly from 37.8 points preoperatively to 76.4 points postoperatively (p < 0.001), and overall sense of health improved significantly from 51.7 preoperatively to 80.7 postoperatively (p < 0.001). Shoe-related results improved from 50.0 points preoperatively to 69.4 points postoperatively (p = 0.038). Only one postoperative complication was noted, which was a case of deep wound infection. Conclusion: Short-term outcomes for cTAA were mostly good in our study population. The findings suggest that talus implants could be used as a treatment option for cases involving severe deformities, crushed talus injuries, and bone defects in which the use of TAA had previously been difficult, which can be handled with cTAA. These findings reveal new possibilities for expanded indications going forward. However, as these were short-term treatment outcomes, further follow-up is required in future studies.

The aim of this study was to evaluate the hearing results of ossiculoplasty in canal wall down tympanoplasty in one stage middle-ear cholesteatoma surgery.We carried out a retrospective review of a consecutive series of 142 cases which had undergone type two or three canal wall down tympanoplasty with ossicular reconstruction, between January 1995 and December 2002, due to chronic otitis media with cholesteatoma.Pre-operative audiometric testing revealed a mean air conduction pure tone average (PTA) of 50.97 dB and a mean bone conduction PTA of 22.14 dB. The mean post-operative result for air conduction PTA was 37.62 and for bone conduction PTA was 23.37 dB. The mean pre- and post-operative air–bone gaps (ABGs) were 28.83 and 13.94 dB, respectively, with a gain of 14.89 dB. Almost 62.67 per cent of patients closed their ABGs to within 20 dB.Our functional results are comparable with those of other authors. In the present study, we show that hearing improvement is possible following cholesteatoma surgery with canal wall down tympanoplasty and ossicular chain reconstruction.

The Mayo Conservative Hip femoral prosthesis has been designed to optimise proximal femoral loading as well as preserving proximal femoral bone stock. Between October 2003 and May 2006, 42 patients (49 hips) underwent total hip replacement (THR) using the Mayo Conservative Hip femoral component. The mean age at operation was 57.8 years (range 44 to 74) and the mean clinical follow up was 3.1 years (range 2.3 to 4.7 years). The aim of our study was to review the short term results of this unorthodox femoral component. We found that 18%° of stems were malaligned ≥ 5° and the prevalence of intra-operative femoral fracture was 4%. We feel this prosthesis is difficult to implant and has an unacceptable fracture rate.

Object The treatment of tethered cord syndromes in adults is discussed regarding the natural history and surgical indications. The author analyzes data obtained in patients who were diagnosed with a tethered cord in adulthood and either underwent surgical or conservative therapy between 1991 and 2009. Methods Since 1991, data obtained in 2515 patients with spinal cord pathologies were entered into the spinal cord database, and prospective follow-up was performed through outpatient visits and questionnaires. Of the 2515 patients, 85 adults with a tethered cord syndrome formed the basis of this study. The tethering effect was caused either by a split cord malformation, a thick filum terminale, a conus medullaris lipoma with extradural extension, or various combinations of these mechanisms. The mean age of the patients was 46 ± 13 years (range 23–74 years) and the mean follow-up duration was 61 ± 62 months. Two groups were distinguished based on the absence (Group A, 43 patients) or presence (Group B, 42 patients) of an associated lipoma or dysraphic cyst (that is, dermoid, epidermoid, or neurenteric cyst). Surgery was recommended for patients with symptoms only. Short-term results were determined within 3 months of surgery, whereas long-term outcomes (clinical recurrences) were evaluated using Kaplan-Meier statistics. Results For all patients, pain was the most common major complaint. Severe neurological deficits were rare. In Group A, 20 of 43 patients underwent surgery, whereas in Group B 23 of 42 patients underwent surgery. Among individuals who did not undergo surgery, 17 patients refused surgery and 25 patients underwent recommended conservative treatment. Short-term postoperative results indicated a significant improvement of pain and a stabilization of neurological symptoms. Long-term results showed a good prognosis in patients in whom first-time (that is, nonrevision) surgery achieved successful untethering, with a 10-year rate of neurological stabilization in 89% of Group A and a 10-year rate of neurological stabilization in 81% of Group B patients. The benefit of secondary operations in Group B was limited, with eventual clinical deterioration occurring in all patients within 10 years. For patients treated conservatively, follow-up information could be obtained in 33 of 42 patients. Twenty-eight patients remained in stable clinical condition. Only 5 of the conservatively treated patients experienced clinical deterioration over time; in 4 of these individuals with deterioration, surgery had been recommended but was refused by the patient. The clinical recurrence rate in all conservatively treated patients was 21% after 10 years. With a recommendation for surgery this figure rose to 47% within 5 years. Conclusions Surgery in adult patients with a tethered cord syndrome should be reserved for those with symptoms. In surgically treated patients, pain relief can often be achieved, and long-term neurological stabilization tends to persist more often than it does in conservatively treated patients. A conservative approach is warranted, however, in adult patients without neurological deficits. Revision surgery in patients with complex dysraphic lesions should be performed in exceptional cases only.

Hearing levels of 174 patients (213 ears operated on) with otosclerosis undergoing stapedectomy were analyzed. All patients had followup of 10 years or more, the mean follow-up period being 13.4 years. Eighty-seven ears (41%) underwent posterior crus stapedectomy, and in the remaining 126 ears (59%) a prosthesis was inserted. Large fenestra technique was used in all cases. In the long run, both air conduction and bone conduction thresholds of ears operated on showed remarkable deterioration from the best values obtained 6 to 12 months postoperatively. Ten years after surgery both air conduction and bone conduction thresholds of ears operated on were significantly worse than those of normal controls. At 10 years, 70 percent of the ears operated on had hearing levels (at 0.5 to 2.0 kHz) of 30 dB or better and 88 percent had 40 dB or better. At the last follow-up examination, in 90% of the patients the better hearing ear had a hearing level of 40 dB or better. In 90% of patients with bilateral otosclerosis who had operations in only one ear, the ear operated on had better hearing function than the opposite ear that had not been operated on.

Abstract Background The ACR/EULAR recommendations endorse the use of glucocorticoids (GCs) for rheumatoid arthritis (RA) patients’ flares and as a bridge to a DMARD. However, the recommendation of low dose short-term monotherapy with (GCs) remains open to the discretion of the clinician. The aim of this study was to assess whether a short-term use of low dose prednisone monotherapy was effective in inducing remission in newly diagnosed RA patients. Methods A retrospective analysis of patients newly diagnosed with RA at a Community Health Center in North Dakota was performed based on the ACR/EULAR RA classification criteria. Demographic and clinical data were abstracted from patients’ medical charts. Patients treated with (< 10 mg/day) of prednisone up to 6 months were included. Response to prednisone was analyzed according to pre- and post-treatment DAS28-ESR score and EULAR response criteria. Results Data on 201 patients were analyzed. The mean prednisone dose was 8 mg/day (range: 5–10; SD = 1.2) and the mean treatment duration was 42.2 days (12–177; 16.9). Disease severity significantly improved from baseline to follow-up for: tender joint count (8.6 ± 4.8 vs. 1.5 ± 3.3; P < 0.001), swollen joint count (6.2 ± 5.0 vs. 1.4 ± 3.0; P < 0.001), and visual analog pain score (4.8 ± 2.6 vs. 2.1 ± 2.5; P < 0.001). DAS28-ESR disease severity significantly improved from baseline to follow-up: (5.1 ± 1.2 vs. 2.7 ± 1.3; P < 0.001). Per EULAR response criteria, 69.7% of patients showed good response to treatment and 20.4% showed moderate response. 54.2% of patients reached remission. Conclusion Short-term use of low dose prednisone monotherapy induced disease remission and improved clinical severity of RA in the majority of newly diagnosed patients.

Abstract Purpose This prospective cohort study reports on a new technique, namely precise safety decompression via double percutaneous lumbar foraminoplasty (DPLF) and percutaneous endoscopic lumbar decompression (PELD) for lateral lumbar spinal canal (LLSC) stenosis, and its short-term clinical outcomes.Methods The study analyzed 69 patients with single-level LLSC stenosis simultaneously occurring in both zones 1 and 2 (defined as retrodiscal space and upper bony lateral recess respectively by new LLSC classification) who underwent DPLF–PELD from November 2018 to April 2019. Clinical outcomes were evaluated according to preoperative, three months postoperatively, and last follow-up, via leg pain/low back pain (LBP) visual analog scale (VAS) scores, Oswestry disability index (ODI) scores, and the Macnab criteria. The postoperative MRI and CT were used to confirm the complete decompression, and flexion-extension x-rays at the last follow-up were used to observe lumbar stability.Results All patients successfully underwent DPLF–PELD, and the stenosis was completely decompressed, confirmed by postoperative MRI and CT. The mean follow-up duration was 13 months (range: 8–17 months). The mean preoperative leg pain VAS score is 7.05 ± 1.04 (range 5–9), which decreased to 1.03 ± 0.79(range: 0–3) at three months postoperatively and to 0.75 ± 0.63 (range: 0–2) by the last follow-up visit(p < 0.05). The mean preoperative ODI was 69.8 ± 9.05 (range: 52–85), which decreased to 20.3 ± 5.52 (range: 10–35) at the third month postoperatively and to 19.6 ± 5.21 (range: 10–34) by the final follow-up visit(p < 0.05). The satisfactory (excellent or good) results were 94.2%. There was one patient with aggravated symptoms, which were relieved after an open surgery. Two patients had a dural tear, and two patients suffered postoperative LBP. No recurrence or segmental instability was observed at the final follow-up.Conclusion DPLF–PELD could be a good alternative for the treatment of LLSC stenosis patients whose stenosis occurred in both zones 1 and 2.Trial registration Chinese Clinical Trial Registry (ChiCTR1800019551).
