Mid-term Follow-Up after Closed Reduction in Developmental Dysplastic Hips

PURPOSE

Closed reduction and subsequent spica casting is the gold standard for treatment of unstable or dislocated developmental dysplastic hips (DDHs). There are few data on mid-term results after treatment of DDH, especially on closed reduction.

METHODS

Thirty-one consecutive patients with unstable or dislocated hips (n = 36) that were treated by fluoroscopic, contrast agent-supported closed reduction and spica casting were included and evaluated clinically and radiologically 2 and 5 years after treatment.

RESULTS

After 2 and 5 years, there were no significant differences between healthy and successfully treated hips that were detectable with respect to acetabular coverage (AC) angle, center-edge angle, and clinical stability of the hip. There was a significant difference at the 2-year follow-up between healthy hips and hips that needed to undergo secondary open reduction surgery (n = 4) with respect to the AC angle (p < 0.001).

CONCLUSION

Closed reduction in DDHs results in acceptable clinical and radiological results in the mid-term follow-up. It remains unclear why some patients with subsequent sonographically matured hips show secondary deterioration and recurrence of dysplasia.

The risk analysis of perioperative complications of cementless hip arthroplasty in octogenarians

INTRODUCTION

Hip arthroplasty is exposed to demographic change as patients age. Analysis of risk factors for surgical treatment decisions in the group of ≥ 80-year-old patients is crucial. Healthcare systems in developed countries are being tested medically and financially by the ageing population. Therefore, this study analysed the perioperative complications of cementless primary hip arthroplasty in octogenarians and compared them with patients aged ≤ 60 years.

METHODS

A retrospective data analysis of the year 2017 was done in a maximum care hospital of General Orthopaedic Surgery. Patients aged ≥ 80 years or ≤ 60 years with primary cementless hip arthroplasty were included. The outcome of interest was surgery-related and systemic complications, the development of haemoglobin and the incidence of blood transfusion after cementless primary hip arthroplasty in octogenarians during the hospitalisation and the follow-up treatment. Chi-square tests and Fischer's exact test were used for nominal variables. The two-factorial variance analysis-mixed model was used for Hb analyses and the Welch test for group comparison for metric parameters.

RESULTS

There was a significantly increased incidence of systemic complications during hospitalisation in the ≥ 80-year-old patients (phi 0.26; Std. Ri - 0.8 (A), 2.2 (B); p = 0.007), as well as a significantly increased rate of blood transfusions (phi 0.403; Std. Ri - 1.3 (A), 3.2 (B); p = < 0.001). No clustered pre-existing conditions in the ≥ 80-year-old patients pointed out a significant association with the incidence of systemic complications. Surgery-related complications showed no significant difference during hospitalisation and follow-up treatment.

CONCLUSION

The study reveals that primary cementless hip prosthesis implantation is a safe procedure without increased incidence of surgery-related complications. Increased attention should be paid to interdisciplinary preoperative optimisation (adjustment of blood pressure, blood transfusions, if necessary, safe exclusion of urinary tract infections) and postoperative care of octogenarians (tight laboratory examinations, geriatric co-attendance).

Total hip arthroplasty in patients with severe hip dysplasia and congenital pubic diastasis: report of two cases

Background

Congenital bladder exstrophy is a rare malformation which is often associated with pubic diastasis and hip dysplasia. We reported the case two patients who underwent total hip arthroplasty (THA) due to advanced osteoarthritis combined with large congenital pubic diastasis (> 10 cm).

Case presentation

The first patient, a 39 years old woman with a pubic diastase and severe hip dysplasia on both sides was treated with a primary two-staged bilateral THA. Both hips were treated with a cementless osteoconductive cup (TM, Zimmer-Biomet) and a cementless stem (Alloclassic SL, Zimmer-Biomet). A 10° elevated rim liner of the cup was used in order to avoid dislocation. The main problem was represented by the fixation of the cup, given the retroverted acetabulum along with the elevated rotation centre due to the dysplastic hips. In the case two, a 52 years woman presented dysplastic osteoarthritis of the left hip. A conventional hemispherical cup (Alloclassic-Allofit, Zimmer-Biomet) was placed in the retroverted acetabulum combined with a cementless stem (Fitmore A, Zimmer-Biomet) attached at the metaphyseal proximal femur bone.

Conclusion

Our results suggest that THA may be a good strategy to manage advanced hip osteoarthritis in patients with dysplasia and congenital pubic diastasis.

AMIC for traumatic focal osteochondral defect of the talar shoulder: a 5 years follow-up prospective cohort study

BACKGROUND

Autologous Matrix-Induced Chondrogenesis (AMIC) is addressed to osteochondral defects of the talus. However, evidence concerning the midterm efficacy and safety of AMIC are limited. This study assessed reliability and feasibility of AMIC at 60 months follow-up. We hypothesize that AMIC leads to good clinical outcome at midterm follow-up.

METHODS

Surgeries were approached with an arthrotomy via malleolar osteotomy. A resorbable porcine I/III collagen membrane (Chondro-Gide®, Geistlich Pharma AG, Wolhusen, Switzerland) was used. Patients were followed at 24 and 60 months. The primary outcome of interest was to analyse the Foot Function Index (FFI), and the subscale hindfoot of the American Orthopaedic Foot and Ankle Score (AOFAS). Complications such as failure, revision surgeries, graft delamination, and hypertrophy were also recorded. The secondary outcome of interest was to investigate the association between the clinical outcome and patient characteristics at admission.

RESULTS

Data from 19 patients were included. The mean age at admission was 47.3 ± 13.2 years, and the mean BMI 24.1 ± 4.9 kg/m². 53% (10 of 19 patients) were female. At a mean of 66.2 ± 11.6 months, the FFI decreased at 24-months follow-up of 22.5% (P = 0.003) and of further 1.3% (P = 0.8) at 60-months follow-up. AOFAS increased at 24-months follow-up of 17.2% (P = 0.003) and of further 3.4 (P = 0.2) at 60-months follow-up. There were two symptomatic recurrences within the follow-up in two patients. There was evidence of a strong positive association between FFI and AOFAS at baseline and the same scores last follow-up (P = 0.001 and P = 0.0002, respectively).

CONCLUSION

AMIC enhanced with cancellous bone graft demonstrated efficacy and feasibility for osteochondral defects of the talus at five years follow-up. The greatest improvement was evidenced within the first two years. These results suggest that clinical outcome is influenced by the preoperative status of the ankle. High quality studies involving a larger sample size are required to detect seldom complications and identify prognostic factors leading to better clinical outcome.

Rupture of plantar fascia: Current standard of therapy: A systematic literature review

BACKGROUND

The aim of the present systematic literature review is to give an overview of ruptures of the plantar fascia. For this purpose, a detailed description of the patient collective is provided. However, the focus of this analysis is based on the current therapy concepts. Based on the results the authors propose a standardized therapy concept.

MATERIAL AND METHODS

A systematic literature review was performed using the PubMed database using the terms: ("rupture plantar fascia" OR "plantar fascia tear" OR "rupture plantar aponeurosis"). All articles published in the PubMed database until 07.11.2018 were included. The articles were evaluated with regard to three research question: (1) Which patients are affected by a rupture of the plantar fascia? (2) Which therapy concept was used to treat rupture of the plantar fascia? And (3) which result was achieved and how was this measured?

RESULTS

A total of 78 studies were identified, of which the full text of 17 were analysed. 12 publications were cases reports, 5 studies were retrospective analyses. Data from 124 patients could be included. The average age of patients was 39.6 years. In 63.2% (n = 12) of the studies, patients with a high level of athletic activity or even professional athletes were analyzed. 94.4% of all patients were treated conservatively. The average duration of immobilization in a rigid walker was 2.6 weeks. In the majority of cases, pain-adapted weight-bearing was allowed in the rigid walker.

CONCLUSION

There are few available studies concerning the rupture of plantar fascia. The quality of data is poor. The maximum duration of immobilization of 3 weeks in a rigid walker with pain-adapted weight-bearing appears to be the most applied therapy concept. Further studies are needed to evaluate the efficacy of the therapy and to optimize the therapy concept.

MRI in patients with Haglund's deformity and its influence on therapy

INTRODUCTION

Heel pain is one of the common reasons why patients consult orthopaedic surgeons in an outpatient setting. The dorsal heel pain is often caused by a Haglund's deformity which is an exostosis of the posterior superior calcaneus. It often leads to Haglund's syndrome with calcaneal bursitis and Achilles tendinosis. This study aims to investigate the roll of MRI in diagnosis of Haglund's syndrome and its influence on therapy.

MATERIALS AND METHODS

We retrospectively analysed data of 45 patients which clinically and radiologically confirmed Haglund's deformity. Patients were divided into two groups that either did not receive MRI (MRI_0) or received MRI (MRI_1). To evaluate the significance, Fisher´s test was used. A statistical significance was assumed at p < 0.05.

RESULTS

The average age was 57.0 years. There was no significant difference in therapy comparing the groups MRI_0 and MRI_1. Haglund's syndrome was detected in 86.7% of all patients with Haglund's deformity.

CONCLUSION

MRI does not influence the therapy of patients with Haglund's deformity. Therefore, the resources of this cost-intensive and limited type of investigation should be used elsewhere. In cases of atypical heel pain, the MRI might be useful.

Changes of gait patterns and muscle activity after intraarticular treatment of patients with osteoarthritis of the knee: a prospective, randomised, doubleblind study

Evaluation of gait performance and muscle activity patterns as well as clinical efficacy and safety after intraarticular injections with hyaluronan (Ostenil) compared with triamcinolone (Volon A10) injections in patients with knee osteoarthritis. This was a prospective, randomised, double-blind clinical trial evaluating the influence of five injections of hyaluronan or triamcinolone on gait pattern and muscle activity. For the clinical evaluation visual analogue scale, Lequesne index, and Knee Society Score were used. Quality of life was estimated with the SF-36. The definitive analysis was performed on the population who received all five injections and were examined in the two follow-up visits. Fifteen patients were treated with triamcinolone and 20 with hyaluronan. Significant improvement could be demonstrated for pain scale and clinical scores in both groups. Gait patterns showed significant differences only for Knee Abduction Moment (p=0.007) in the hyaluronan group and for Maximum Vertical Force 1 and 2 between the both groups in the follow up visit (p=0.018) (p=0.019). In both groups there was no significant difference regarding to muscle activity. Quality of life showed no changes in all visits between the groups. Hyaluronan was not superior to triamcinolone. The results suggest that treatment with hyaluronan can reduce pain and improve knee function. A significant short term improvement in gait and muscle activity patterns, however, was not observed, in either hyaluronan or triamcinolone.

High- versus low-energy extracorporeal shock wave therapy of rotator cuff tendinopathy: a prospective, randomised, controlled study

A prospective, controlled, randomised trial was performed to compare the effect of high-energy extracorporeal shock wave therapy (ESWT) versus low-energy ESWT in treatment of rotator cuff tendinopathy. Forty adult patients were included in the study. Patients in the intervention group received 6000 impulses of high-energy (ED+ 0.78 mJ/mm2) in 3 sessions under local anaesthesia. Patients in the control group received 6000 impulses of a low-energy ESWT (ED+ 0.33 mJ/mm2) under local anaesthesia. Follow-up examinations were performed 12 weeks and one year after treatment by an independent observer. An increase in function and a reduction of pain were found in both groups (p < 0.001). Although the improvement in Constant score was greater in the high-energy group compared to the low-energy group, statistical analyses showed no significant difference between the groups with respect to all parameters studied (Constant score/pain/subjective improvement) after 12 weeks and one year follow-up. No statistically significant differences were found between the results of high-energy and low-energy ESWT of rotator cuff tendinopathy.

[Arthroscopically-assisted combined anterior and posterior cruciate ligament reconstruction]

BACKGROUND

The best treatment of a combined rupture of the anterior and posterior cruciate ligaments is still unclear.

METHODS

Nine patients with unilateral traumatic ruptures of both the anterior and posterior cruciate ligaments were treated by arthroscopically-assisted simultaneous reconstruction. The operation was done using hamstring tendon and patellar tendon autografts, an average of 235 days (range 52-567) after the initial trauma. Patients were followed up for an average of 37 months (range 24-58) after surgery. For this retrospective cohort study, we used the Lysholm knee score, the Tegner activity score, and the SF-36 questionnaire as a means of assessment.

RESULTS

The evaluation at follow-up showed an average score of 74 points on the Lysholm scale. Using the IKDC evaluation, four patients could be placed in group B and five patients in group C. A significant increase, from 1.9 points before trauma to 5.0 points at follow-up, was observed on the Tegner activity score. Comparing the operated with the healthy knees, with respect to stability and isokinetic muscle strength, we noted significantly better scores in the healthy knees. Using the SF-36 questionnaire, patients showed a reduced level of physical well-being.

CONCLUSION

The treated patients were able to carry out their activities of everyday life. However, none of them returned to their preinjury activity level.
