Abstract Purpose The aim of this article is to present an original surgical technique for the treatment of rigid Adult Idiopathic Scoliosis (AdIS) and the results at minimum 2 years follow-up in a cohort of 40 patients. Methods We retrospectively reviewed 40 patients affected by rigid AdIS, older than 40 years and operated with a posterior one stage surgical technique summarized with the acronym Hi-PoAD, (high-density pedicle screws, Ponte osteotomies, asymmetric rods contouring, direct vertebral rotation). The demographic and surgical data were collected, and the improvement of clinical scores and radiologic parameters was obtained after surgery, at 1 and 2 years and at final follow-up, to assess deformity correction, coronal and sagittal balance and clinical outcome. Results The average follow-up was 2.9 years (range 2–3.5). Average coronal Cobb angle decreased from 65.0° ± 8.4 to 18.9° ± 3.9 (p < 0.01). Rotation sagittal angle decreased from 26.2° ± 4.4° to 12.4° ± 2.8° (p < 0.01). Mean thoracic kyphosis improved from 23.1° ± 3.6° to 36.0° ± 3.9°. SRS-22 improved form 2.9 ± 0.4 to 3.7 ± 0.6 (p < 0.01). Four early post-operative deep wound infections were observed, all healed after debridement and implant retention. No mechanical complication, junctional kyphosis, deformity progression or non-union were recorded at the last follow-up. Conclusions Hi-PoAD technique proved to be safe and effective in the treatment of rigid Adult Idiopathic Scoliosis. The reason for the success is related to the combined strategies adopted, that dissipates corrective forces over several levels, reducing mechanical stress at the screw–bone interface and optimizing corrective potential.

Abstract BACKGROUND: The optimal treatment of Lenke 5C curves in adolescent idiopathic scoliosis is still unclear. OBJECTIVE: To compare the outcomes and the spontaneous correction behavior between anterior and posterior selective fusion techniques in a large case series. METHODS: Demographic and surgical data for patients with Lenke 5C curves treated with anterior or posterior fusion were collected from July 2002 to September 2011. Clinical assessment and radiographic parameters were compared preoperatively and postoperatively and at a minimum of 2 years of follow-up. RESULTS: Fifty-three Lenke 5C adolescent idiopathic scoliosis cases with an average follow-up of 4 years (range, 2-9.6 years) were included. The clinical scores were similar between the 2 groups. Postoperative major thoracic curvature changes were similar. The minor thoracic curve demonstrated a higher spontaneous correction rate in the posterior group. At follow-up, the minor thoracic curve showed a greater loss of correction in the posterior group, and finally both groups were comparable. Surgical time, intraoperative blood loss, and complications were comparable. A total of 5 patients had a final thoracic curve larger than the preoperative degrees. CONCLUSION: Selective fusion of the major thoracolumbar/lumbar curve in Lenke 5C adolescent idiopathic scoliosis can be achieved by anterior and posterior techniques. The spontaneous correction of the unfused thoracic curve was comparable after an average of 4 years follow-up.

Category: Bunion, Midfoot/Forefoot Introduction/Purpose: Hallux valgus combines two deformities, the metatarsus varus and metatarsal internal rotation. The rotational deformity is seldom corrected during surgery, but is a known recurrence factor. Most techniques only correct the metatarsus varus (scarf, chevron, etc). We present a prospective case series using a novel metatarsal rotational osteotomy called PROMO (proximal rotational metatarsal osteotomy) which simultaneously corrects the metatarsal internal rotation and varus deformity by rotating the metatarsal through an oblique plane osteotomy. This is performed with no bone resection. Our objective was to report this new technique, preliminary results, its advantages and complications. Methods: 20 consecutive patients (17 women) with Hallux Valgus, average age 45 (25-55), were operated using this technique. The average preoperative intermetatarsal angle (IMA) was 15 degrees with an average Hallux internal malrotation of 30 degrees and a sesamoid malposition of grade V or more in all cases. Postoperatively, sesamoids position, Hallux rotation, IMA and metatarsal length were registered. They were followed for 1 year (8-14 months). The surgical technique is described, with its potential benefits and drawbacks. The radiological outcome, postoperative LEFS score, recurrence rate (IMA increase >5 degrees) and complications were registered. Results: Well positioned sesamoids (grade IV or less) were obtained in all patients postoperatively, with a complete Hallux rotational correction. Postoperative IMA was 5 degrees. achieving a complete metatarsal varus correction. No metatarsal shortening was observed whatsoever. No recurrence has been observed until final follow up. Preoperative and postoperative LEFS scores were 58 and 73 respectively. Conclusion: The PROMO has the advantage over other osteotomies that it can reliable correct, both metatarsal malrotation and varus deformities, achieving a complete deformity correction and hopefully decreasing recurrence rate. The surgical technique has been studied and refined extensively, in order to simplify it and make it reliable. Although more patients and follow-up are needed, the authors believe it is a promising surgical technique which addresses a previously not considered hallux valgus deformity component.

Abstract The aim of this study is to evaluate the results of patients underwent lateral open wedge calcaneus osteotomy with bony allograft augmentation combined with tibialis posterior and tibialis anterior tenodesis. Twenty-two patients underwent adult-acquired flatfoot deformity were retrospectively evaluated with a minimum 2-year follow-up. Radiographic preoperative and final comparison of tibio-calcaneal angle, talo–first metatarsal and calcaneal pitch angles have been performed. The Visual Analog Scale, American Orthopedic Foot and Ankle Score, the Foot and Ankle Disability Index and the Foot and Ankle Ability Measure were used for subjective and functional assessment. The instrumental range of motion has been also assessed at latest follow-up evaluation and compared with preoperative value. There was a significant improvement of final mean values of clinical scores (p < 0.001). Nineteen out of 22 (86.4%) patients resulted very satisfied or satisfied for the clinical result. There was a significant improvement of the radiographic parameters (p < 0.001). There were no differences between preoperative and final values of range of motion. One failure occurred 7 years after surgery. Adult-acquired flatfoot deformity correction demonstrated good mid-term results and low recurrence and complications rate. Level of evidence Level 4, retrospective case series.

Abstract BackgroundThe surgical technique of radius distraction for stabilization of distal radioulnar joint (DRUJ) if intraoperative DRUJ instability was found after the fixation of distal radius fracture has been previously described, but this surgical technique lacks clinical and radiographic effect in minimal 3 years follow-up. We therefore evaluated the clinical outcome and radiographic results of radius distraction in minimal 3 years follow-up.MethodsWe reviewed the case series of distal radius fracture with concomitant DRUJ instability receiving radius distraction from the senior author over a 5-year period (January 1st, 2013 to June 30th, 2017) retrospectively, and the evaluation of clinical and radiographic outcomes was performed at clinic as long-term follow-up; a total 34 patients had been evaluated.ResultsAt minimal post-operative 36 months follow-up, all cases demonstrated acceptable wrist range of motion with stable DRUJs and low NRS of wrist pain (0.6, SD 0.7) and DASH score (mean 9.1, SD 6.2), and there were no cases suffering from nonunion of distal radius. The mean ulnar variance of injured wrist and uninjured wrist were − 1.2 mm and 0.2mm, respectively (SD 1.0 and 0.6) with significant statistical difference.ConclusionsRadius distraction during volar fixation of distal radius fracture should be consider if DRUJ instability was found by the radioulnar stress test intraoperatively, and the long-term DRUJ stability could be achieved by maintenance of normal-to-negative ulnar variance, with decreased wrist pain and satisfactory function outcome.Level of EvidenceTherapeutic Level IV

Introduction: Talar fractures are uncommon injuries, whose outcome is often characterized by the onset of serious complications. The aims of the present study are: 1) to review the available evidence concerning the outcome and complications of talar neck fractures; 2) to describe the clinical results and the rate of post-op complications in a series of patients treated surgically after talar fracture-dislocations. Materials and methods: The review of the literature was performed on the Pubmed, Embase and Web of Science databases and aimed at identifying clinical trials with at least 10 patients and dealing with surgical management of talar fracture-dislocation (Hawkins grade II to IV). All the papers were analyzed to extract data concerning common complications such as non-union, mal-union, infection, osteonecrosis and osteoarthtritis. The clinical arm of this paper included 26 patients (19 men and 7 women), who underwent fixation of displaced talar fracture by cannulated screws and were retrospectively evaluated, both clinically and radiographically, at a mean 51.2 ± 23.4 months of follow-up. Results: The evaluation through the AOFAS score revelead a loss of functional performance with respect to the pre-injury status. Four patients were re-operated within final follow up, whereas the remaining 22 presented excellent results in 2 cases, good results in 4 cases, fair results in 11 cases and poor results in 5 cases. Osteoarthritis and osteonecrosis incidence were 51.9% and 25.9% respectively. Sixteen studies were included in the review and it was confirmed that the most frequent complication was post-traumatic OA, followed by osteonecrosis and mal-union. A variable range in percentage of complications described should be ascribed to the low quality of trials currently available. Conclusion: Displaced talar fracture are challenging to treat and the outcomes at middle-term are often modest. Looking at complications, the present case series and the review of literature revealed that the most common one is peritalar OA. Osteonecrosis, traditionally regarded as the most fearsome adverse event, is relevant but less frequent than OA.

ABSTRACT Objectives: To compare the outcomes of surgical treatment with lumbar fixation using nitinol rods without fusion and with standard lumbar fixation with titanium rods and interbody fusion. Methods: Treatment results of 70 patients with degenerative lumbar scoliosis aged 40 to 82 were analyzed. In all cases pedicle screws and nitinol rods with a diameter of 5.5 mm were used. Thirty patients underwent fixation at L1-S1 and 40 patients underwent fixation at L1-L5. Spinal fusion was not performed. All patients had radiography, CT and MRI performed. The results were assessed according to the Oswestry scale, SRS 22, SF 36 and VAS. The minimum follow-up period for all patients was 2.5 years. For the control group, consisting of 72 patients, pedicle fixation with titanium rods and interbody fusion in the lumbosacral region were performed. Results: The average level of deformity correction equaled 25° (10° - 38°). The analysis of X-ray and CT-scans revealed a single patient with implant instability, two patients with bone resorption around the screws and one patient with rod fractures. Functional radiography 2.5 years after surgery showed an average mobility of the lumbar spine of 21° (15° - 30°). There were no problems at the adjacent levels. Conclusions: The use of nitinol rods in spinal deformity surgery is promising. This technology is an alternative to rigid fixation. Continued gathering of clinical data and its further evaluation is necessary.

ABSTRACT Introduction: Adolescent idiopathic scoliosis is the most common type of scoliosis. A Cobb angle of 50° will progress beyond the age of spinal maturity. Surgery over bracing is advised at a Cobb angle above or equal to 50°. The aim of surgery is to bring the Cobb angle down below 50° to prevent reprogression as well as improve the quality of life. The objective of the study is to analyze the efficacy and significance in lifestyle improvement of pedicle screw-only fixation system versus the more common hybrid instrumentation system used for the surgical treatment of adolescent idiopathic scoliosis. Materials and Methods: A prospective cohort study was conducted involving two groups of patients were included in the study. One group was operated with pedicle screw-only method while the other with hybrid instrumentation system. The pre- and post-operative Cobb’s angles were taken across a follow-up of 4 years. An SRS-30 questionnaire was given in a yearly follow-up to assess the lifestyle improvement of the patient. Results: Pedicle screw-only method was significantly more effective in reducing Cobb’s angle (P = 0.0487). It was showed less loss of correction (P = 0.009) pedicle screw-only surgery was also better at reducing thoracic curves (P = 0.001). There seemed a better recovery time with pedicle screw surgery (P = 0.003). Conclusion: Pedicle screws are more effective and durable than hybrid systems at when treating adolescent idiopathic scoliosis.

Background: Various operative procedures have been reported for the treatment of Müller-Weiss disease (MWD). This study reports the midterm operative treatment results for stages II to V MWD with derotation of the talus and arthrodesis. Methods: Thirty-four patients (36 feet) with MWD were treated by talonavicular (TN) or talonavicular-cuneiform (TNC) arthrodesis in our center from 2008 to 2015. The affected feet were staged according to the Maceira staging system (stage II: 9; stage III: 10; stage IV: 9; stage V: 8). The American Orthopaedic Foot & Ankle Society (AOFAS) midfoot scale, the visual analog scale (VAS), and relative radiologic parameters were evaluated preoperatively and also during follow-up. The mean follow-up duration was 38.2 (range, 25-113 months). Results: The final follow-up showed satisfactory outcomes. Overall, the AOFAS scores improved from 41.5 (range, 20-56) to 85.3 (range, 68-100) points ( P <.001), and the VAS score decreased from 5.7 (range, 3-8) to 0.9 (range, 0-4) points ( P <.001). The Tomeno-Méary angle decreased from −6.7 (range, −26.4 to 17.7) to 0.7 (range, −5.3 to 7) degrees ( P=.001). The calcaneal pitch angle increased from 13.7 (range, 4.1-26.2) to 22.0 (range, 13.3-28.9) degrees ( P < .001). The anteroposterior (AP) talar–first metatarsal angle decreased from −15.8 (range, −30.1 to −13.7) to −7.0 (range, −25.9 to −8.9) degrees ( P < .001), and the AP talocalcaneal angle increased from 14.7 (range, 4.7-22.3) to 22.1 (range, 13.4-29.5) degrees ( P=.005). The AP talonavicular coverage angle decreased from −27.0 (range, −40.4 to −13.3) to −7.8 degrees (range, −20.7 to −1.8) degrees ( P < .001). Conclusion: The midterm results found that the TN or TNC joint fusion could achieve a favorable clinical and radiologic outcome for patients with MWD. Even for the patients with severe deformities (stages IV-V), this treatment strategy could also achieve satisfactory deformity correction and functional improvement. Intraoperative restoration of talus rotation was the key to normal alignment of the subtalar joint/TN joint. Level of Evidence: Level IV, retrospective case series.

The purpose of the study is to describe features of the surgical technique for correction of kyphotic deformity of the spine and to analyze the results of surgical treatment of juvenile kyphosis in children with the use of 3D-CT navigation.— Materials and methods. We observed 11 patientsaged 14-17 years old (2 girls and 9 boys) with kyphoticdeformity of the spine, developed on the backgroundof Scheuermann’s disease. The deformity amount aver-aged 73,9° (60 to 90°). Surgery was performed fromthe combined access, carring out discapophysectomyand corporodesis on top of kyphosis and fixing mul-tibasic corrective metal construction. For the insertionof pedicle screws we used 3D-CT navigation.— The results. After surgery kyphosis value decreasedto 32,6° (20 to 45°), the deformity correction averaged41,3° (30 to 50°). Hybrid systems were placed in 5 pa-tients, total transpedicular fixation - in 6 children.Number of fixed vertebrae with hybrid metal construc-tions averaged 14 (13 to 15), in patients with total pediclefixation - 13 (12 to 14). In all cases we observed the correct position of pedicle support elements. Postopera- tive follow-up period was from 1 year and 5 months to5 years and 4 months, on average - 3 years 5 months. The loss of the result achieved in the long-term follow- up period was observed in patients with hybrid metal constructions and averaged 7,2° (4 to 9°).— Conclusion. The use of pedicle screws for thecorrection of juvenile kyphosis in children allows forthe effective correction of the deformity, restoring thephysiological profiles of the spine, eliminating post-operative progression of curvature, and reducing thelength of metal fixation and save the result achievedin the long-term follow-up. The use of active optical3D-CT navigation allows carring out a correct inser-tion of pedicle screws in the vertebral bodies in chil-dren with juvenile kyphosis.— Keywords: Scheuermann’s disease, juvenile ky-phosis, transpedicular fixation, navigation, children,surgical treatment.

Background: Different interpositional materials have been used to prevent recurrence after gap arthroplasty in temporomandibular joint ankylosis. In this study, the temporalis superficial fascia flap was evaluated as an interpositional material after condylectomy. Materials and Methods: 9 Cases of unilateral or bilateral temporomandibular joint ankylosis were evaluated in this study with a follow-up of 12 months. The Al-khayat approach was used as the surgical technique with the inferiorly based temporalis superficial fascia flap. Results: 9 Patients (6 female and 3 male) had a preoperative maximal inter-incisal opening of 3 to 10 mm. During the last follow-up observation after surgery, patients had a maximum inter-incisal opening of 40 to 45 mm. Paresthesia or anesthesia of the temporal branch of facial nerve was absent in all cases. There were no signs of re-ankylosing in any of the patients. Conclusion: The findings of this study showed that the temporalis superficial fascia flap is a good alternative as an interpositional material in treatment of temporomandibular joint ankylosis.
