Early results of ceramic/ceramic fist metatarsophalangeal joint replacement

We set out to evaluate the early outcome of ceramic on ceramic (MOJE) prosthesis in the treatment of hallux rigidus. Between March 2000 and November 2003, 13 patients (14 implants), were treated using the ceramic/ceramic prosthesis. These patients have been followed for an average of 24.46 months. The American Orthopaedic Foot Association scoring system (AOFAS) was used to assess the patients before and after surgery. The average AOFAS score significantly increased from 43.07 pre-operatively to 95.28 post-operatively (P = 0.0001). At 6 months, 12 patients had no pain. The total range of dorsiflexion and plantarflexion improved to greater than 75° in 10 patients. Audible squeaking of the prosthesis, which improved between 3 and 6 months, was noted in 12 patients.The early results are encouraging with good functional outcome. Long-term follow-up is required to assess the durability of the ceramic/ceramic press fit prosthesis.

An early comparison of clinical and mechanical aspects of hybrid and uncemented hip resurfacing

Hip resurfacing is a popular operation for hip joint arthritis. It has been performed using hybrid and uncemented components. We aim to compare the two techniques functionally and mechanically over a 2 year post-operative period. We studied anteroposterior (AP) radiographs from 30 patients who had undergone hybrid hip resurfacing and 30 patients who had undergone uncemented hip resurfacing using the transgluteal approach to the hip. We measured the acetabular offset, femoral offset, stem/shaft angle, medialization of the cup, head/neck ratio, cup height, leg length and the implant seating pre-operatively, immediately post-operatively, 1 and 2 years post-operatively. Harris Hip Scores were performed pre-operatively and at 1 year post-operatively. There was no significant loss of offset and no femoral neck thinning at 2 years post-operatively with no loss of leg length. We note a smaller femoral offset and a reduction on average of 2.87 mm in seating of the femoral cap in the uncemented group when compared to the hybrid group at the 1 year postoperative review. Thus, we attribute to movement of the femoral component in the first year postoperatively, and as such restoration of the femoral offset to the pre-operative level. Both groups showed an equal significant improvement in the Harris Hip Scores at the 1 year postoperative period when compared to the pre-operative score. We conclude that uncemented hip resurfacing is statistically as good as the hybrid hip resurfacing, with a stable uncemented femoral component relying on biological cancellous fixation rather than cement fixation. We also note that in both groups, no evidence of neck thinning was noted at the 2 year postoperative period.     

Does the MONARC transobturator suburethral sling cause post-operative voiding dysfunction? A prospective study

The aim of this study was to compare pre-operative and post-operative voiding parameters following insertion of the MONARC transobturator tape (TOT), for treating women with urodynamic stress incontinence. This prospective observational study was conducted at a tertiary referral urogynaecology unit, in North Queensland, involving 83 women who were prospectively assessed pre-operatively and at 6–8 weeks following the procedure. Information collected included patient demographics, concomitant surgery, pre-operative and post-operative symptomatology (using validated questionnaires), and pre-operative and post-operative urodynamic parameters. Parameters used to assess voiding function included symptoms of voiding difficulty (incomplete emptying and irritative symptoms) as well as objective parameters including maximum flow rate (Q_max), adjusted maximum flow rate (Q_maxadj) using the Liverpool nomogram (LN), maximal urethral pressure, and post-void residual (PVR). Pre-operative average Q_max was 23.7 ml/s compared to 21.1 ml/s post-operatively (p=0.064). When the Q_max was adjusted for voided volume using the LN, Q_maxadj was seen to decrease significantly from 26 ml/s to 18 ml/s (p<0.05). Women with PVR>50 ml did not differ significantly pre-operatively and post-operatively, 5/83(6%) vs 7/83 (8.4%) (p=0.75). The number of women with a flow rate <10th centile on LN was 22 (26.5%) pre-operatively vs 29 (34.9%) post-operatively (p=0.21). One (1.2%) post-operatively had voiding dysfunction diagnosed by an abnormal voiding pattern (p=0.728), which was not statistically significant. Objective voiding dysfunction as determined by adjusted flow rates <10th centile LN and >50 ml PVR was seen in four women (4.8%). Adjusted free flow rates are significantly reduced following insertion of the MONARC TOT, as are some symptoms related to voiding dysfunction. Despite this, satisfaction rates remain high with observed voiding dysfunction or objective measures of voiding dysfunction showing no statistical change in the short term. Long-term follow-up is planned at 1 year.     

The effect of psychological status on pain and surgical outcome in patients requiring arthroscopic subacromial decompression

Background

We prospectively investigated the association between pre-operative psychological status and early post-operative shoulder pain and function in patients requiring arthroscopic subacromial decompression for impingement syndrome.

Methods

A consecutive series of patients in 2009/10 completed questionnaires 2?weeks pre-operatively and three and 6?weeks post-operatively that assessed psychological state, shoulder function and pain. The hospital anxiety and depression scale, the oxford shoulder score and a pain visual analogue scale assessed psychological status, shoulder function and shoulder pain, respectively.

Results

Thirty-one patients participated (21 women; 10 men; mean age 54.6?years; age range 21–89?years). Pre-operative anxiety was significantly associated with pre-operative shoulder pain (P?<?0.05). Pre-operative psychological status did not correlate with post-operative shoulder pain or function. Greater pre-operative anxiety and depression were significantly associated with post-operative psychological distress (P?<?0.05). Overall shoulder pain, function and psychological state improved significantly during the study (P?<?0.05) regardless of pre-operative psychological status.

Conclusion

Despite pre-operative associations between anxiety and shoulder pain, there were no associations between pre-operative psychological status and post-operative outcomes. There may be no justification for assessing psychological state in cases of ‘uncomplicated’ impingement syndromes requiring arthroscopic subacromial decompression. Abnormal pre-operative psychological status is not a justifiable reason for delaying or denying this effective operation.     

Proximal oblique-domed osteotomy of the first metatarsal for the treatment of hallux valgus associate with flat foot: effect to the correction of the longitudinal arch of the foot

Introduction Flat foot and/or metatarsal primus varus are the major causes of hallux valgus, and it is important to correct these deformities in order to prevent the recurrence of this condition. We demonstrate the clinical and radiological assessment of the correction of hallux valgus, metatarsal primus varus, and flat foot after proximal oblique-domed osteotomy of the metatarsus with distal soft tissue reconstruction. Materials and methods Twenty-seven feet of 22 patients with moderate or severe hallux valgus who had undergone proximal oblique-domed osteotomy were studied. After the adductor hallucis tendon was cut at the attachment of the proximal phalanx and at the sesamoid bone, the osteotomy was performed 3 cm dorsal-distal to the metatarsocuneiform joint to transfer distal fragment approximately 5 mm in the plantar direction, and rotated laterally decreasing the first–second intermetatarsal angle to 5 degrees. Results The mean AOFAS score was 54.1 ± 2.8 points at pre-operation and 92.8 ± 4.8 points at the most recent follow-up (P < 0.0001). Significant improvement was seen between the hallux valgus angle (P < 0.0001), first–second intermetatarsal angle (P < 0.0001), first–fifth intermetatarsal angle (P < 0.0001), talar pitch (P = 0.0032), and calcaneal plantar angle (P = 0.0327) before surgery and at one year after surgery. The average improvement of the talar pitch and calcaneal plantar angle was 2.6 ± 1.4 and 2.4 ± 1.5 degrees, respectively. Conclusion This study suggest that proximal oblique-domed osteotomy of the metatarsal as a surgical procedure for the treatment of moderate or severe hallux valgus with flat foot can be recommended to correct the longitudinal arch of the foot and the first–second intermetatarsal angle.

The long-term patient focused outcomes of the Keller's arthroplasty for the treatment of hallux rigidus

BackgroundThe Keller arthroplasty has been used to treat painful conditions of the first MTP joint for over 100 years. More recently the procedure has fallen out of favour, due to a high incidence of transfer metatarsalgia and poor function of the first MTP joint post-operatively.ObjectiveThis study sought to review the place for Keller arthroplasty in the management of hallux rigidus by considering outcomes from the patient's perspective.MethodsFrom 1997 to 2005, 104 patients (131 feet) underwent a Keller excisional arthroplasty for the treatment of hallux rigidus. All subjects were classed as grade III on the Hattrup and Johnson scale of joint classification and had a primary complaint of painful hallux rigidus. The American orthopaedic foot and ankle scale was applied pre-operatively and post-operatively.Thirty-two participants (42 feet) were available for a final review (6 male feet and 34 female feet). The range of follow up was 36–154 months with a mean average follow up of 92 months (7.6 years). The age range at the time of surgery was 42–78 years with a mean average age of 62 years at surgery and 69 years and eight months at review.ResultsSeventy-six percent of participants were completely satisfied, 21.5% satisfied with reservations and 2.5% were dissatisfied. High levels of satisfaction were recorded for pain relief, activity levels and overall patient satisfaction. Ninety-five percent of participants reported their symptoms were improved at long-term follow up compared to pre operatively; however 9.5% of the group complained of transfer metatarsalgia. Nineteen percent of participants, all female, were not happy with the cosmetic appearance of their foot. The mean pre-operative AOFAS clinical rating scale scores was 38. At final follow up the mean score was 89.ConclusionThe Keller excisional arthroplasty is a simple reliable procedure for the treatment of severe hallux rigidus. Furthermore, it is effective in achieving pain-free movement of the first MTP joint, but carries a risk of creating transfer metatarsalgia. For nearly 20% of participants post-operative cosmetic appearance was disappointing.     

When should quality of life be measured after radical cystectomy?

AIM: In this prospective study our aim was to establish the time it takes cystectomized patients' to adapt to their new health status. MATERIALS AND METHOD: A total of 68 patients, having radical cystectomy for bladder cancer (64 males and 4 females) were enrolled in the study. The mean age of the group was 55.4 +/- 8.0 years (range 38-70 years). Continent urinary diversion was applied to 17 while the rest had incontinent urinary diversions. There was no statistical difference between those who had continent and incontinent diversions in regard to pre-operative stage. All patients were given a Beck's Depression Inventory (BDI), an EORTC-QLQ C-30 Version 2 (European Organization for Research on Treatment of Cancer Quality of Life Questionnaire C-30 Version 2) quality of life measurement scale pre-operatively, and post-operatively 3, 6, 12 and >12 months (every 6 months). Log-rank and Student's t-test was used for statistical analysis of the results. RESULTS: The mean follow-up of the study group was 27.7 +/- 7.3 months (range 12-46 months). Five patients at the first 3rd-month control, seven at the 6th-month control and eight at the 12th-month control did not appear for interview, but their available results were also included in the overall assessment. The mean functional score of the study group, evaluated by QLQ C-30, was 80 +/- 25.4 pre-operatively. There is dramatic decrease at the 3rd-month control (56.9 +/- 25.1; p < 0.01). The overall functional score after 12 months (80 +/- 20) is back to the pre-operative value. The mean symptom score of the group pre-operatively was 29.5 +/- 16.7, which showed similar results at 3 and 6 months post-operatively of 29.8 +/- 16.7 and 30.6 +/- 19.4, respectively (p > 0.05). At the 12th-month and thereafter the symptom scores of the patients decreased significantly in comparison to both the pre-operative and the post-operative 3-6 months (23.4 +/- 13.7 and 21.8 +/- 18.5, respectively; p < 0.01 for all). The self-rating general health status of this group was lowest pre-operatively with a mean of 49.8 +/- 26.5. Interestingly, there was a statistically significant increase in the general health status assessment of the patients even at the early post-operative period of 3 months (61.4 +/- 17.2; p < 0.01). The increase in the well-being of the patients increased linearly until the 12th-month control and stabilized thereafter. There was a 23% pre-operative depression rate, which comes down to 16% at the 12th-month control. The peak depression scores suggesting depression are observed at the 3rd-month controls. There is a gradual decrease in depression score starting from the 6th-month controls and all reach minimum scores after 12 months. Ninety-six percent of the study group showed scores even lower than the pre-operative ones. The mean pre-operative and post-operative 12th-month control scores were 11.5 +/- 7.7, and 8.1 +/- 6.8, respectively (p < 0.01). CONCLUSION: Both psychological and health-related quality of life measures come to baseline values and stabilize after the 12th-month period, suggesting that the time frame for the adaptation of patients is 12 months in patients undergoing radical cystectomy surgery. Therefore, we believe it is better to perform any quality of life assessment as an end-point criterion for comparison of treatment modalities in radical cystectomy patients after 12 months.

目的评价经后外侧人路行距下关节撑开植骨融合术治疗陈旧性跟骨骨折畸形愈合的临床疗效。方法回顾性研究自2009-03-2012—10收洽的采用后外侧人路距下关节撑开植骨融合术治疗且获得完整随访的27例陈旧性跟骨骨折畸形愈合患者。定期随访观察术后切口愈合、骨折愈合及内固定情况,比较手术前后距骨跟骨角、距骨第1跖骨角、美国足踝外科协会（AOFAS）踝与后足评分。结果27例术后获平均20（12～36）个月随访,切口均一期愈合,无皮缘坏死、切口感染及内固定物、跟骨骨质外露发生。术后4～6个月X线片显示27例融合处均骨性愈合。距骨跟骨角由术前平均（15．8±3．0）°改善至术后平均（24．8±1．9）°,距骨第1跖骨角由术前平均（16．9±3.2）°改善至术后平均（5．6±1．9）°,AOFAS评分由术前平均（33．9±7．9）分提高至术后平均（84．9±7．5）分,差异均有统计学意义（P〈0．05）。结论跟骨后外侧人路可清楚显露距下关节,能在直视下对距下关节面进行彻底清理,撑开植骨矫正跟骨内、外翻畸形,恢复足弓,矫正或减轻跟骨骨折畸形愈合的主要病理改变,有效地改善症状,减少切口并发症,临床疗效满意。     

The prevalence of depressive symptoms before and after surgery and its association with disability in patients undergoing lumbar spinal fusion

Purpose

The aim of this study was to evaluate the prevalence of depressive symptoms and disability pre-operatively, at 3 months and at 1 year after lumbar spine fusion surgery.

Methods

Data was extracted from a dedicated lumbar spine fusion register, giving 232 patients (mean age 62 years, 158 females) who had undergone instrumented lumbar spine fusion. The frequency of depressive symptoms and disability was evaluated using the Depression Scale (DEPS) and Oswestry Disability Index (ODI).

Results

Depressive symptoms were found in 34, 13, and 15 % of the patients pre-operatively, at 3 months and at 1 year after surgery, respectively. The mean DEPS score decreased from 16.2 to 8.6 (p < 0.001) in patients who had depressive symptoms pre-operatively, and from 6.1 to 3.8 (p < 0.001) in those patients without pre-operative depressive symptoms. The mean ODI values pre-operatively, at 3 months and at 1 year after surgery were 53, 30, and 23, respectively, in patients with pre-operative depressive symptoms and 41, 23, and 20 in those patients without pre-operative depressive symptoms. The differences between the groups were statistically significant at all time points (p < 0.001).

Conclusions

One-third of our patients with chronic back pain undergoing spinal fusion had depressive symptoms pre-operatively. The prevalence of depressive symptoms decreased after surgery. Although disability remained higher in those patients who had reported depressive symptoms pre-operatively, disability did decrease significantly in both groups post-operatively. Thus, there is no need to exclude depressive patients from operation, but screening measures and appropriate treatment practises throughout both pre-operative and post-operative periods are encouraged.     

踝关节骨折畸形愈合的重建手术

Abstract：

Objective To summarize the clinical outcomes of reconstruction of malunited ankle fractures.Methods From January 2006 to October 2009,23 malunited ankle fractures were treated in our department.All deformities were evaluated individually based on pre-operatively X-ray and CT scan.Varying degrees of fibular shortening or rotational deformity were found in all patients,with 4 cases of varus or valgus deformity,and 5 of a widen syndesmosis.Then different reconstructive techniques were chosen according to the type of malunion:a lengthening fibular osteotomy was performed in patients with fibular shortening or rotational deformity;an opening or closing wedge osteotomy was chosen correspondingly in patients with varus or valgus deformity;functional fusion of syndesmosis was performed in cases of widen syndesmosis.The postoperative follow-up included standard radiography to evaluate bone union;relative complications were also recorded and functional outcome were assessed with American Orthopedic Foot Ankle Society (AOFAS)ankle-hindfoot scores.Results Twenty-one patients were followed up with an average period of 36 months (12-58 months).There were no complications of infection,implant failure,nonunion or malunion.Solid union with a favorable alignment was obtained at an average of 12 weeks (10-14 weeks).The mean pre-operative AOFAS ankle-hindfoot score was 28 (15-39).While the score increased to 82 (70-94) one year after operations.But 2 patients underwent ankle arthrodesis correspondingly 18 months and 24 months post-operatively due to severely post-traumatic arthritis.Conclusion An early realignment reconstruction of the length and rotation of fibula and the congruity of ankle mortise may improve the ankle function and slow down the development of post-traumatic arthritis for patients who suffered from malunited ankle fractures.     

Balloon kyphoplasty in the treatment of metastatic disease of the spine: a 2-year prospective evaluation

There is currently little data on the longer term efficacy and safety of balloon kyphoplasty (BKP) in patients with metastatic vertebral compression fractures (VCFs). To prospectively assess the long-term efficacy and safety of BKP in treating thoracic and lumbar spinal metastatic fractures that result in pain or instability. Sixty-five patients (37 men, mean age: 66 years) underwent 99 BKP procedures. Patient-related outcomes of pain visual analogue scale (VAS) and Oswestry Disability Index were assessed pre- and post-operatively and after 3, 6, 12 and 24 months. Correction of vertebral height and kyphotic deformity were assessed by radiographic measurements. Mean pain VAS and Oswestry Disability Index significantly improved from pre- to post-treatment (P < 0.0001), this improvement being sustained up to 24-month follow up. A gain in height restoration and a reduction of the post-operative kyphotic angle were seen post-operatively and at 3 months although these radiographic outcomes returned to pre-operative levels at 12 months. BKP was associated with a rate of cement leakage and incidence vertebral fracture of 12 and 8%, respectively. No symptomatic cement leaks or serious adverse events were seen during the 24 months of follow up. BKP is a minimally invasive procedure that provides immediate and long-term pain relief and improvement in functional ability in selected patients with metastatic VCFs. The procedure appears to have good long-term safety.     

Chevron osteotomy in hallux valgus. Ten-year results of 112 cases

The Chevron osteotomy was described in 1976. There have, however, been only short- to mid-term follow-up reviews, often with small numbers of patients. We looked at 112 feet (73 patients) with a minimum follow-up of ten years following Chevron osteotomy with a distal soft-tissue procedure. Clinical evaluation was calculated using the hallux score of the American Orthopedic Foot and Ankle Society (AOFAS). For 47 feet (30 patients), the results were compared with those from an interim follow-up of 5.6 years. The AOFAS-score improved from a pre-operative mean of 46.5 points to a mean of 88.8 points after a mean of 12.7 years. The first metatarsophalangeal (MTP) angle showed a mean pre-operative value of 27.6 degrees and was improved to 14.0 degrees. The first intermetatarsal (IM) angle improved from a pre-operative mean value of 13.8 degrees to 8.7 degrees. The mean pre-operative grade of sesamoid subluxation was 1.7 on a scale from 0 to 3 and improved to 1.2. Measured on a scale from 0 to 3, arthritis of the first MTP joint progressed from a mean of 0.8 to 1.7. Comparing the results in patients younger and older than 50 years, the Chevron osteotomy performed equally in both age groups. Analysing the subgroup of 47 feet with a post-operative follow-up of both 5.6 and 12.7 years, the AOFAS pain and the overall score showed a further improvement between both follow-up evaluations. The MTP angle, first IM angle and sesamoid position remained unchanged. The progression of arthritis of the first MTP joint between 5.6 and 12.7 years post-operatively was statistically significant. Only one patient required a revision procedure due to painful recurrence of the deformity. Excellent clinical results following Chevron osteotomy not only proved to be consistent, but showed further improvement over a longer follow-up period. The mean radiographic angles were constant without recurrence of the deformity. So far, the statistically significant progression of first MTP joint arthritis has not affected the clinical result, but this needs further observation.     

Three-dimensional displacement after a medializing calcaneal osteotomy in relation to the osteotomy angle and hindfoot alignment

BackgroundA medializing calcaneal osteotomy is frequently performed to correct adult-acquired flatfoot deformities, but there is lack of data on the associated three-dimensional variables defining the final correction. The aim of this study was to assess the correlation between the pre-operative hindfoot valgus deformity and calcaneal osteotomy angles and the post-operative calcaneal displacement.MethodsWeight-bearing CT scans obtained pre- and post-operatively were retrospectively analyzed for sixteen patients. Corresponding three-dimensional bone models were used to measure valgus deformity pre- and post-operatively, inclination of the osteotomy and displacement of the calcaneus. Linear regression was conducted to assess the relationship between these measurements.ResultsOn average, the hindfoot valgus changed from 13.1° (±4.6) pre-operatively to 5.7° (±4.3) post-operatively. A mean inferior displacement of 3.2 mm (±1.3) was observed along the osteotomy with a mean inclination of 54.6° (±5.6), 80.5° (±10.7), −13.7° (±15.7) in the axial, sagittal and coronal planes, respectively. A statistically significant positive relationship (p < .05, R² = 0.6) was found between the pre-operative valgus, the axial osteotomy inclination, and the inferior displacement.ConclusionsThis study shows that the degree of pre-operative hindfoot valgus and the axial osteotomy angle are predictive factors for the amount of post-operative inferior displacement of the calcaneus. These findings demonstrate the added value of a computer-based pre-operative planning in clinical practice.Level of evidence II Prospective comparative study.     

Sinonasal outcomes associated with the use of BioGlue® in endoscopic transsphenoidal pituitary surgery

Concerns have been raised in the neurosurgical literature regarding the use of BioGlue®, a tissue sealant initially developed for cardiothoracic surgery, due to reports of an increased incidence of infection, wound breakdown, and CSF fistulae. The aim of this study was to determine if the use of BioGlue® in skull base repair impacts on the sinonasal outcomes and the incidence of post-operative infection following endoscopic pituitary surgery. SNOT-22 questionnaires were completed pre-operatively, and at 6, 12, and 24 weeks post-operatively by 50 patients. Pre- and post-operative MRI scans were reviewed and assessed for evidence of post-operative sinusitis. Patient records were consulted to ascertain the incidence of post-operative infection. Repeated measures ANOVA and Wilcoxon signed rank test were used for data analysis. Statistical analysis revealed a significant difference in the mean SNOT-22 scores across the four time intervals (F(1.605, 78.642)?=?9.180, p?=?0.001). This difference was powered by a deterioration at 6 weeks that recovered completely by 12 weeks. The mean SNOT-22 score in the study cohort at 24 weeks was 16.84/110 (range 0–57,?±?2.04) which was lower than the mean pre-operative score and is consistent with mild rhinosinusitis. There were no cases of post-operative meningitis and 1/50 (2%) case of post-operative sinusitis in this cohort. The use of BioGlue® in endoscopic endonasal pituitary surgery does not appear to lead to significant sinonasal morbidity. Previous concerns about the use of BioGlue® in transcranial procedures may not apply to extradural application of this tissue sealant in endoscopic transnasal surgery.
