OBJECTIVE In this study, the authors aimed to describe a new technique of sacroiliac joint (SIJ) fusion using a robotic navigation guidance system and to document clinical results with patient-reported visual analog scale (VAS) scores. METHODS Patients diagnosed with SIJ dysfunction were surgically treated using 2 hydroxyapatite (HA)–coated, threaded screws with the aid of the robotic navigation system. In a total of 36 patients, 51 SIJs were fused during the study period. Patients’ VAS scores were used to determine clinical improvement in pain. Postoperative imaging at routine intervals during the follow-up period was also performed for assessment of radiological fusion. In addition, complication events were recorded, including reoperations. RESULTS All 36 patients had successful fusion evidenced by both CT and clinical assessment at the final follow-up. Two patients underwent reoperation because of screw loosening. The mean preoperative VAS score was 7.2 ± 1.1, and the mean 12-month postoperative VAS score was 1.6 ± 1.46. This difference was statistically significant (p < 0.05) and demonstrated a substantial clinical improvement in pain. CONCLUSIONS Robotic navigation–assisted SIJ fusion using 2 HA-coated, threaded screws placed across the joint was an acceptable technique that demonstrated reliable clinical results with a significant improvement in patient-reported VAS pain scores.

ABSTRACTPlantar fasciitis is a disorder caused by inflammation of the insertion point of the plantar fascia over the medial tubercle of the calcaneus. Foot orthotics are used to treat plantar fasciitis. Heel pads medialise the centre of force, whereas medial arch supporting insoles lateralise the force. We assessed the clinical results of the treatment of plantar fasciitis with silicone heel pads and medial arch-supported silicone insoles.We retrospectively reviewed 75 patients with heel pain. A total of 35 patients in the first group were treated with medial arch supporting insoles, and 40 patients in the second group were treated with heel pads. The patients were evaluated with the Visual Analogue Scale (VAS) and the Foot and Ankle Ability Measure (FAAM) at the first and last examinations.The mean VAS score in the first group was 8.6±1,2 (6-10); the FAAM daily activity score was 66.2±16 (41.2-95.0), and the sporting activity score was 45.4±24,4 (0.1-81) before treatment. At the last follow-up in this group, the mean VAS score was 5.3±1,5 (0-9); the FAAM daily activity score was 83,0±15,1 (55,9-100), and the sporting activity score was 73,5±26,2 (25-100). The mean VAS score in the second group was 8,6±0,9 (7-10); the FAAM daily activity score was 66.4±17 (41.4-95.2), and the sporting activity score was 45.8±24,2 (0.8-81, 3) before the treatment. At the last follow-up in this group, the mean VAS score was 5.5±1,2 (0-9); the FAAM daily activity score was 83.4±14,9 (60, 2-100), and the sporting activity score was 73.8±26 (28-100).There was no significant difference in the clinical results of both groups. The force distribution by the use of silicone heel pads and medial arch-supported silicone insoles had no effect on the clinical results of the treatment of plantar fasciitis.

Background: Both the percutaneous technique with arthroscopic assistance, also known as arthroscopic Broström (AB), and the arthroscopic all-inside ligament repair (AI) are widely used to treat chronic lateral ankle instability. The aim of this study was to compare the clinical outcomes of these 2 arthroscopic stabilizing techniques. Methods: Thirty-nine consecutive patients were arthroscopically treated for chronic ankle instability by 2 different surgeons. The AB group comprised 20 patients with a mean age of 30.2 (range, 18-42) years and a mean follow-up of 19.6 (range, 12-28) months. The AI group comprised 19 patients with a mean age of 30.9 (range, 18-46) years and mean follow-up of 20.7 (range, 13-32) months. Functional outcomes using the American Orthopaedic Foot & Ankle Society (AOFAS) hindfoot score and visual analog pain scale (VAS) were assessed pre- and postoperatively. Range of motion (ROM) and complications were recorded. Results: In both groups the AOFAS and VAS scores significantly improved compared with preoperative values ( P < .001) with no difference ( P > .1) between groups. In the AB group the mean AOFAS score improved from 67 (range, 44-87) to 92 (range, 76-100) and the mean VAS score from 6.4 (range, 3-10) to 1.2 (range, 0-3). In the AI group the mean AOFAS score changed from 60 (range, 32-87) to 93 (range, 76-100) and the mean VAS score from 6.1 (range, 4-10) to 0.8 (range, 0-3). At the final follow-up 8 complications (40%) were recorded in the AB group. In the AI group 1 complication (5.3%) was observed ( P < .05). Conclusion: Both the AB and AI techniques are suitable surgical options to treat chronic ankle instability providing excellent clinical results. However, the AB had a higher overall complication rate than the AI group, particularly involving a painful restriction of ankle plantarflexion and neuritis of the superficial peroneal nerve. Level of Evidence: Level III, retrospective comparative study.

Object The goal of this report was to describe the authors' initial experiences with an adjustable gravity-assisted valve (GAV) called the ProGAV in treating childhood hydrocephalus. Methods The ProGAV was implanted in 53 children (29 boys and 24 girls, median age 7.3 years) with hydrocephalus of various origins. The ProGAV consists of a differential-pressure unit with adjustable opening pressures and a gravitational unit with a fixed opening pressure. Results The mean follow-up period was 15.2 months (range 6–44 months). The authors did not observe any valve-related complications. Four infections (7.5%) occurred, warranting the removal of the shunt. In 19 children, the opening pressure was changed at least once during the follow-up period, for underdrainage in 10, overdrainage in 8, and shunt weaning in 1, with substantial clinical improvement in 18 children. Overall, good clinical results were obtained in 47 (88.7%) of the 53 valve placements. Conclusions With an overall success rate of 88.7%, the first experiences with the ProGAV in childhood hydrocephalus are promising and justify its further use in the pediatric population.

Category: Trauma Introduction/Purpose: Calcaneal fracture is the most common fracture in hindfoot. The treatment is challenging, because of various patterns of fractures and high complication rates which leads to high level of dysfunction and low satisfaction of the patients. There are many previous studies reporting various methods about treatment of calcaneal malunion, such as subtalar arthrodesis, corrective osteotomy and corrective osteotomy with subtalar arthrodesis. However, there are no mid-term clinical results reporting about lateral ostectomy and sliding osteotomy, which is called calcaneal reconstruction. The purpose of this study is to evaluate the mid-term clinical and radiologic results of calcaneal reconstruction in the patients who have chronic complications after calcaneal fracture. Methods: Between January 2009 to May 2014, 196 patients (257 feet) were treated by calcaneal fracture. 34 patients (37 feet) underwent calcaneal reconstruction because of the dysfunction and the pain caused by malunion. Inclusion criteria were those whom underwent calcaneal reconstruction and able to be followed up at least 4 years postoperatively. The patients who had severe subtalar arthritis or whom underwent subtalar arthrodesis or simple bone resection were excluded. We reviewed 10 patients (10 feet) postoperatively and at mid-term follow up. Radiologic results including Böhler angle, calcaneal pitch, talocalcaneal height, talar inclination, talocalcaneal angle, talo-1st metatarsal angle, calcaneal width were measured and clinical results including AOFAS Ankle-Hindfoot scale and VAS score were checked preoperative, postoperatively and at the last follow up. The satisfaction of the patient was checked by survey. Results: The mean interval between the first operation and reconstructive operation was 16.6 months. The mean follow-up period after calcaneal reconstruction was 67.1 months. The most common symptom of the patient were pain on the inferior aspect of the lateral malleolus (4 patients) and heel area (3 patients). After calcaneal reconstruction, all the mean values of talocalcaneal height, calcaneal pitch, and Böhler angle were improved, which was statistically significant, respectively. In the postoperative period, 3 patients were very satisfied, 5 were satisfied, and 2 were not satisfied. The results maintained till mid-term follow up. Also, AOFAS and VAS score were improved comparing pre-reconstruction and mid-term follow up. Although the pain did not completely resolved, most of the patients were satisfied postoperatively. Conclusion: In patients without severe subtalar arthritis, the known main causes of the pain in calcaneal malunion are the loss of calcaneal height and hindfoot widening rather than subtalar arthritis. Our results showed signigficant clinical and radiological results by calcaneal reconstruction. And the outcome maintained till mid-term follow up. Calcaneal reconstruction can be a good choice for chronic pain which is caused by malunion of calcaneal fracture without severe subtalar arthritis.

Background: The usefulness of radial osteotomy for older patients remains unclear. The purpose of this study was to compare the clinical and radiological outcomes of radial osteotomy with volar locking plate between younger and older patients with Kienböck disease stages II to IIIB. Methods: This was a retrospective comparative study of 21 consecutive patients treated at our department. Lichtman’s classification was used for staging, and four patients had stage II, six patients had stage IIIA, and 11 patients had stage IIIB disease. We divided them into two groups to compare the radiological and clinical results between younger (younger than 40 years) and older patients. The mean follow-up periods in the younger and older groups were 4 and 3.6 years, respectively. For radiological assessment, we evaluated the carpal height ratio (CHR), Stahl index, and union of the fractured lunate. For clinical assessment, we examined the range of motion of the wrist, grip strength, numeric rating scale (NRS) for pain, and the patient-reported Hand20 score preoperatively and at the final follow-up. Results: There were 12 patients in the younger group with a mean age of 23 years (range, 12–37 years), and 9 in the older group with a mean age of 56 years (range, 40–74 years). There were no intra- and post-operative complications in either group. Radiological improvement, including CHR, Stahl index, and union of the fractured lunate, was more common in the younger group than in the older one, as was the case for clinical improvement. However, even in the older group, significant clinical improvement, including the range of motion of the wrist, NRS for pain, and the Hand20 score, was seen postoperatively. Conclusions: Radial osteotomy appears to be a safe and reliable option in older symptomatic patients with Kienböck disease stages II to IIIB.

Abstract Background Although the Nirschl technique was introduced approximately 40 years ago, only limited information is available about the long-term results, especially concerning extensor power changes after surgery. The purpose of this study was to investigate long-term clinical results of surgical treatment of lateral epicondylitis using the modified Nirschl technique. The main outcome variable was muscle strength for wrist extension because the extensor origin was not reattached after removal of the degenerative extensor tendon. Methods Data from 99 patients who underwent surgical lateral epicondylitis treatment between 2007 to 2012 were included in the study. The mean follow-up period was 8.5 years (5 to 10, ± 1.1 years) and the mean age at surgery was 44.8 years (32 to 70, ± 9.8 years). The surgeries were performed using the modified Nirschl method and did not include extensor origin reattachment. Outcome measurements included the Visual Analogue Scale (VAS) score, Disabilities of the Arm, Shoulder and Hand (DASH) score, the MAYO elbow performance score, and Nirschl and Pettrone’s grades. Wrist extension and grip strength were analyzed using a digital handgrip dynamometer (microFET2TM system) and JAMA hand dynamometer. Results Mean time required to return to work was 2.4 months after surgery. At the last follow-up after surgery, the mean VAS score had significantly improved, from 4.9 to 1.1. Mean MAYO elbow performance scores significantly improved, from 64 to 90, and mean DASH scores improved from 50 to 13. The Nirschl and Pettrone’s grades were 80% rated as ‘excellent’ and 16% rated as ‘good’. After adjusting for power differences between the dominant and non-dominant arms, the difference between wrist extensor power of the operated elbow and the non-operated opposite elbow at the final follow-up was not statistically significant. No patients complained about wrist extension weakness. Conclusion Although reattachment of the extensor origin was not performed during the modified Nirschl surgical technique, there was no significant weakness in wrist extension power and the long-term follow-up revealed favorable clinical results. Level of evidence Level IV (case series). Retrospective study.

Objectives: Medial patellofemoral ligament reconstruction (MPFLR) using allograft tissue has several potential benefits including the absence of donor site morbidity, ability to predict graft parameters, and decreased operative time. The purpose of this study was to evaluate the outcomes of patients following MPFLR with allograft. Our hypothesis was that there would be a low rate of recurrent instability, and excellent clinical outcomes reported. Methods: A retrospective review of athletes who underwent MPFL Reconstruction, with a minimum of 12-month follow-up was performed. Recurrent instability (including re-dislocation and subluxation), Visual Analogue Scale (VAS) score, Kujala score, satisfaction, and whether they would undergo the same surgery again, were evaluated. Results: Overall, follow up was attained for 131 patients with 141 knees (73.4%). The mean patient age of 25.0 years, 67.4% females, and mean time to follow-up was 46.8 months (12-111). At final follow up, the mean VAS score was 1.4 ± 2.0, the mean Kujala score was 84.8 ± 15.6, the mean satisfaction score was 84% ± 26.0, and 117 (83.0%) would undergo the same procedure again if required. There was 17 (12.0%) patients that had recurrent instability, with 2 being re-dislocations (1.4%). A further procedure was performed in 14 patients (9.9%). There were no intra-operative complications in our series. Conclusions: There was a low rate of recurrent instability following MPFLR with allograft, with excellent patient reported outcomes, and a low complication rate.

Objective: Percutaneous endoscopic transforaminal lumbar discectomy (PETLD) can be performed by using foraminal, intervertebral, and suprapedicular routes. The aim of this study was to assess clinical results of three different routes of PETLD.Methods: One hundred and eleven patients who underwent PETLD between January 2016 and October 2016 were included in this study. PETLD was performed using the foraminal (group A), intervertebral (group B), and suprapedicular (group C) routes in 32, 46, and 33 patients, respectively. Outcomes were evaluated using the visual analogue scale (VAS), Oswestry Disability Index (ODI), and MacNab criteria.Results: Seventy-one men and 40 were women (mean age 53.33 ± 14.12 years). The mean follow-up period was 6.44 ± 3.26 months. The preoperative VAS score decreased significantly (P < 0.01) in all 3 groups, but the postoperative VAS score was higher for the foraminal route than the intervertebral (P<0.001) and suprapedicular routes (P< 0.001). Excellent outcome grade according to MacNab criteria was less in foraminal route (18.7%) than in intervertebral (52.2%) and suprapedicular (56.7%) routes. ODI improved significantly (P< 0.01) in all 3 groups.Conclusion: All 3 routes of PETLD resulted in good to excellent clinical results. Nevertheless, the postoperative VAS score was higher for the foraminal route than the intervertebral and suprapedicular routes, probably because of the neurologic characteristics of the disk location. The surgeon should consider this problem to alleviate pain postoperatively and to better counsel the patient before surgery.

ObjectiveTo compare problems reported in the five EQ-5D-3L dimensions and EQ VAS scores at baseline and at 1-year follow-up among different patient groups and specific diagnoses in 11 National Quality Registers (NQRs) and to compare these with the general population.DesignLongitudinal, descriptive study.Participants2 66 241 patients from 11 NQRs and 49 169 participants from the general population were included in the study.Primary and secondary outcome measuresProportions of problems reported in the five EQ-5D-3L dimensions, EQ VAS scores of participants’ own health and proportions of participants and mean/median EQ VAS score in the Paretian Classification of Health Change (PCHC) categories.ResultsIn most of the included registers, and the general population, problems with pain/discomfort were the most frequently reported at baseline and at 1-year follow-up. Mean EQ VAS score (SD) ranged from 45.2 (22.4) among disc hernia patients to 88.1 (15.3) in wrist and hand fracture patients at baseline. They ranged from 48.9 (20.9) in pulmonary fibrosis patients to 83.3 (17.4) in wrist and hand fracture patients at follow-up. The improved category of PCHC, improvement in at least one dimension without deterioration in any other, accounted for the highest proportion in several diagnoses, corresponding with highest improvement in mean EQ VAS score.ConclusionsThe study documented self-reported health of several different patient groups using the EQ-5D-3L in comparing with the general population. This demonstrated the important role of patient-reported outcomes in routine clinical care, to assess and follow-up health status and progress within different groups of patients. The EQ-5D-3L descriptive system and EQ VAS have an important role in providing a ‘common denominator’, allowing comparisons across NQRs and specific diagnoses.Trial registration numberClinicalTrials.gov (NCT04359628).

Object In the modern era, stereotactic radiosurgery is an important part of the multidisciplinary and multimodality approach used to treat dural carotid-cavernous fistulas (DCCFs). Based on the ease of performance of techniques to fuse cerebral angiography studies with MR images or CT scans during the radiosurgical procedure, the Gamma Knife and XKnife are 2 of the most popular radiosurgical instruments for patients with DCCF. In this study, the authors compared the efficacy, neurological results, and complications associated with these 2 radiosurgical devices when used for DCCF. Methods Records for 41 patients with DCCF (15 treated using the XKnife and 26 with Gamma Knife surgery [GKS]) were retrieved from a radiosurgical database encompassing the period of September 2000 to August 2008. Among these patients, at least 2 consecutive MR imaging or MR angiography studies obtained after radiosurgery were available for determining radiological outcome of the fistula. All patients received regular follow-up to evaluate the neurological and ophthalmological function at an interval of 1–3 months. The symptomatology, obliteration rate, radiation dose, instrument accuracy, and adverse effects were determined for each group and compared between 2 groups. The data were analyzed using the Student t-test. Results The mean age of the patients was 63 ± 2.6 years, and the mean follow-up period was 63.1 ± 4.4 months (mean ± SD). Thirty-seven patients (90%) achieved an obliteration of the DCCF (93% in the XKnife cohort and 88% for the GKS cohort). In 34 of 40 patients (85%) with chemosis and proptosis of the eyes, these symptoms were resolved after treatment (4 had residual fistula and 2 had arterializations of sclera). All 5 patients with high intraocular pressure demonstrated clinical improvement. Ten (71%) of 14 patients with cranial nerve palsy demonstrated improvement following radiosurgery. Significant discrepancies of treatment modalities existed between the XKnife and GKS groups, such as radiation volume, conformity index, number of isocenters, instrument accuracy, peripheral isodose line, and maximum dosage. The XKnife delivered significantly higher radiation dosage to the lens, optic nerve, optic chiasm, bilateral temporal lobe, and brainstem. Few adverse events occurred, but included 1 patient with optic neuritis (GKS group), 1 intracranial hemorrhage (XKnife group), 1 brainstem edema (XKnife), and 3 temporal lobe radiation edemas (XKnife). Conclusions Radiosurgery affords a substantial chance of radiological and clinical improvement in patients with DCCFs. The Gamma Knife and XKnife demonstrated similar efficacy in the obliteration of DCCFs. However, a slightly higher incidence of complications occurred in the XKnife group.
