Clinical outcomes of gingivoperiosteoplasty for unilateral cleft lip and palate performed in early childhood.

Conventional gingivoperiosteoplasty (GPP) performed during infancy adversely affects maxillary development. However, the outcomes of this procedure in early childhood have rarely been reported. Therefore, we examined the postoperative outcomes of GPP conducted in patients aged 1.5 years with unilateral cleft lip and palate (UCLP). This study included 87 non-syndromic patients with complete UCLP who had undergone early two-stage palatoplasty during the 1999-2004 period. The protocol comprised soft palate plasty at 1 year of age and hard palate closure at 1.5 years of age. In the GPP group (n = 34), we introduced the GPP procedure during hard palate closure; in the non-GPP group (n = 53), the labial side of the alveolar cleft remained intact. We examined computed tomography images taken at 8 years of age to observe bone formation at the alveolar cleft site. We also conducted cephalometric analysis to examine maxillary development at 12 years of age. Bone bridges at the alveolar cleft site were observed in 92% and 5.6% of the GPP and non-GPP groups, respectively. Moreover, 56% of the GPP group did not require secondary alveolar bone grafting (sABG), whereas all the patients in the non-GPP group underwent sABG. No statistically significant differences were noted in the maxillary anteroposterior length (GPP: 45.5 ± 3.7 mm, non-GPP: 45.9 ± 3.5 mm, p = 0.67) and sella-nasion-point A angle (GPP: 75.6 ± 4.5°, non-GPP: 73.8 ± 12.6°, p = 0.49). This study's findings suggest that GPP performed at 1.5 years of age minimises the necessity of sABG and does not exert a negative influence on maxillofacial development.

Arthroscopic matched osteoplasty of the radial head for painful radiocapitellar osteoarthritis: surgical technique and case series.

Background: Radiocapitellar arthritis can cause pain, loss of motion, and impaired elbow function. Current surgical treatment options are limited. We have developed an original and simple surgical technique to address this, called arthroscopic matched osteoplasty of the radial head (AMOR). In AMOR, the radial head is partially resected and recontoured to match the capitellum and decompress the degenerate radiocapitellar articulation while preserving the ulnohumeral articulation where the cartilage is usually well preserved. Methods: Indications and the surgical technique of the AMOR procedure are described. A retrospective observational service evaluation study was conducted from electronic patient records. Collected clinical outcomes included range of motion, pain level, subjective functional score, and general satisfaction with the results of the procedure. The radiographic outcome was radiocapitellar joint space. Results: Between 2017 and 2021, eight consecutive patients underwent AMOR as part of an arthroscopic osteocapsular arthroplasty procedure. Radiographically, the mean radiocapitellar joint space improved from an average of 1.7 mm to 4.6 mm. Clinically, the mean pain score decreased from 8/10 to 3/10. Six of the eight patients (75%) were satisfied with their results. In two cases, initial improvement following surgery lasted less than 1 year, and one of these patients underwent total elbow arthroplasty for painful ulnohumeral osteoarthritis. There were no complications of surgery recorded. Conclusions: AMOR is a safe treatment option for painful radiocapitellar osteoarthritis and can be incorporated as an "add-on" procedure by surgeons performing elbow osteocapsular arthroplasty. Level of evidence: IV.

Soft Tissue Retraction Maneuver in Cone Beam Computed Tomography Prior to Crown-Lengthening Procedure-A Technical Note.

Background: An accurate determination of the biological width and the relationship of the cemento-enamel junction with the border of the alveolar bone is crucial during a clinical crown-lengthening (CCL) procedure. The aim of this study was to present a technical note about the retraction techniques in cone beam computed tomography (CBCT) prior to CCL, highlighting the significant enhancement in procedural accuracy and predictability that these techniques offer. Methods: Clinical and radiological examinations should be performed before a CCL procedure. It is necessary to determine the length of the tooth crowns, the periodontal pockets' depth, and the phenotype of the gingiva. The ideal CBCT examination should be performed with soft tissue retraction. This can be achieved using retractors or cotton rolls. Results: Retraction of the lips, cheeks, and tongue allows one to assess the marginal gingiva, the cemento-enamel junction, and the alveolar bone. A detailed plan of the CCL procedure, which involves retraction, ensures both the aesthetic appeal and the achievement of a newly defined gingival zenith, enhancing the overall visual harmony. Conclusions: Compared with conventional radiographic imaging, the soft tissue retraction maneuver in CBCT prior to CCL surgery offers an effective approach to the evaluation and diagnosis of soft and hard tissue. This is because of the detailed planning of the aesthetic CCL procedure. Such an approach leads to superior aesthetic outcomes in dentistry, contributing to the advancement of aesthetic dentistry through a harmonious blend of art and science.

Clinical Efficacy of Percutaneous Osteoplasty Under Fluoroscopy and Cone-Beam CT Guidance for Painful Sternal Metastases: A Case Series.

Background: Although percutaneous osteoplasty (POP) has been widely accepted and is now being performed for the treatment of painful bone metastases outside the spine. It is emerging as one of the most promising procedures for patients with painful bone metastasis who are unsuitable for surgery or who show resistance to radiotherapy and/or analgesic therapies. However, there are only scarce reports regarding osteoplasty in painful sternal metastases. Subjects and Method: We report four patients with sternal metastases suffered with severe pain of anterior chest wall. The original tumors included lung cancer and thyroid cancer. For the initially pain medication failing, all the four patients received POP procedure under fluoroscopic and cone-beam CT (CBCT) guidance, and obtained satisfying resolution of painful symptoms at 6-month postop follow-up. Conclusion: POP is a safe and effective treatment for pain caused by metastatic bone tumors in the sternum. In practice, however, percutaneous puncture of pathologic sternal fractures can be a challenge because of the long flat contour and the defacement by lytic tumor of bony landmarks. We find that the use of fluoroscopic and CBCT can facilitate POP for flat bone fractures with displacing the trajectory planning, needle advancement, and cement delivery in time.

Staged esthetic crown lengthening: Classification and guidelines for periodontal-restorative therapy.

OBJECTIVE: This article presents technical guidelines for perio-restorative esthetic crown lengthening, along with a discussion of the biologic rationale. A classification system is proposed to assist in treatment planning and sequencing the surgical and restorative phases. CLINICAL CONSIDERATIONS: When esthetic crown lengthening is performed as an adjunct to restorative therapy, the surgical approach must be determined by the anticipated position of the restorative margins. The removal of sufficient bone to achieve the desired clinical crown length and preserve the supracrestal gingival tissue dimensions is facilitated by the use of a surgical guide fabricated according to the design of the restorations. A staged approach allows sequencing the provisional restoration to minimize unesthetic sequelae during the healing period. Inadequate bone resection and/or alteration of the soft tissue dimensions results in delayed healing, leading to coronal gingival rebound and biologic width impingement. CONCLUSION: The identification and preservation of appropriate restorative and biologic landmarks is essential for success in pre-prosthetic esthetic crown lengthening treatment. A staged approach improves the esthetic management during the postsurgical healing and maturation period. CLINICAL SIGNIFICANCE: A restorative driven classification system for sequencing and staging adjunctive esthetic crown lengthening procedures is presented. Technical guidelines to enhance gingival margin predictability are suggested, accompanied by relevant evidence. In addition, wound healing timelines following gingival and osseous resection are provided.

Clinical efficacy and safety of microwave ablation combined with percutaneous osteoplasty for palliative treatment in pelvic osteolytic metastases.

OBJECTIVES: To evaluate the impact of microwave ablation (MWA) on pain relief, quality of life, mobility, and local tumour progression in adult patients with pelvic osteolytic bone metastasis and to test the safety of MWA. METHODS: This study retrospectively analysed the data from 20 patients with pelvic osteolytic metastases who received MWA combined with percutaneous osteoplasty (POP). The visual analogue scale (VAS), musculoskeletal tumour society system (MSTS), and Quality of Life Questionnaire-Bone Metastases 22 (QLQ-BM22) were used to evaluate the pain, limb function, and quality of life. The intraoperative and postoperative complications were recorded. The tumour recurrence and survival time were analysed during the follow-up period (range 3-26 months). RESULTS: All (n = 20) MWA and POP operations were completed successfully. Four patients (20%; 95% CI, 6%-44%) had mild bone cement leakage from surrounding tissues, and there were no obvious symptoms or serious complications. There were significant differences in VAS, MSTS, and QLQ-BM22 scores before and after the operation (P < .001). During the postoperative follow-up period, 9 patients died. The median survival time was 8 months (range 3-26 months; IQR: 4.5-13; 95% CI, 4.2-15.3 months), and the 1-year survival rate was 65% (13/20; 95% CI, 41%-85%). Tumour recurrence occurred in 4 cases (20%; 95% CI, 6%-44%) after the operation, and the median time of recurrence was 12 months (range 8-16 months; IQR: 8.25-12.75; 95% CI, 5.5-18.5 months). CONCLUSIONS: MWA combined with POP is an effective and safe treatment for pelvic osteolytic metastases. It can significantly relieve local pain, reconstruct limb function, improve patients' quality of life, and effectively control local tumour progression. ADVANCES IN KNOWLEDGE: So far, the experience of using microwave in the treatment of pelvic metastases is still limited. MWA combined with POP in the treatment of pelvic osteolytic metastases can provide significant clinical benefits in acceptable low-risk minimally invasive situations and should be provided to patients with appropriate pelvic metastases in a multidisciplinary approach.

An exchange technique in temporomandibular joint (TMJ) arthroscopy to insert a larger operative cannula to facilitate advanced procedures.

The paper describes a modification of the surgical technique for temporomandibular joint arthroscopy, using an exchange guide to replace the 2.2 mm cannula with one of 2.9 mm to better facilitate osteoplasty of the medial wall. The procedure is a simple and safe manoeuvre that reduces complications such as fluid extravasation into soft tissues, damage to the articular eminence, and bleeding into the superior joint space. Every oral and maxillofacial surgeon could benefit from this novel method, which reduces the chances of failure when exchanging the working cannulas, the potential morbidity of re-entry, and the duration of surgery.

Application of cementoplasty in patients with symptomatic benign osteopathy disease.

BACKGROUND: The optimal treatment for some symptomatic, benign osteopathy lesions is yet to be identified. PURPOSE: To investigate the clinical efficiency of cementoplasty in managing symptomatic, benign osteopathy. MATERIAL AND METHODS: Between June 2006 and January 2020, we retrospectively enrolled 31 patients (10 men, 21 women; mean age = 46.5 ± 16.6 years; age range = 20-85 years), accounting for 34 treatment sites, who underwent percutaneous osteoplasty (14 treatment sites) and percutaneous vertebroplasty (20 treatment sites) with digital subtraction angiography (DSA) or DSA combined with computed tomography (CT). All the participants experienced different degrees of clinical symptoms with benign osteopathy lesions. The technical success of the procedure and occurrence of complications were recorded. Follow-up examinations were conducted to assess the treatment outcome using the MacNab criteria. RESULTS: All the participants had a diagnosis of benign osteopathy lesions before or after the cementoplasty. Surgery was successfully completed in all patients. Cement distributions were diffuse and homogeneous, with the complication of cement leakage occurring in 17.6% (6 of 34) of the lesions. The leakage occurred in the intervertebral disc (n = 1), the intra-articular space (n = 1), and the surrounding soft tissue (n = 4). Analysis of the treatment outcome using the MacNab criteria revealed that all patients showed improvement in their clinical symptoms to some extent and in the quality of life. CONCLUSION: Cementoplasty is an effective treatment for symptomatic, benign osteopathy, with the advantage of favorable clinical outcomes, and low complication rate.

Objective To evaluate the clinical efficacy and safety of CT-guided percutaneous osteoplasty(POP)in the treatment of osteolytic metastases of the pelvis.Methods The clinical data of a total of 40 patients with pelvic osteolytic metastases,who received CT-guided POP at the Affiliated Zhongda Hospital of Southeast University between October 2011 and December 2021,were collected.Visual analogue scale(VAS)score was used to evaluate the clinical pain relief degree at one week,one month,3 months,6 months and 12 months after POP,and the joint function and the used dose of analgesic drugs were recorded.The preoperative and the postoperative 3-month,6-month and 12-month extents of the pelvic tumor destruction were compared.Based on the progression of local lesions within 12 months of follow-up,the patients were divided into controlled group and progression group.The proportion of using systemic anti-tumor therapy,the size of lesion,the amount of bone cement injected,and the cement filling ratio were compared between the two groups.Results Successful surgical procedure was accomplished for 57 lesions in 40 patients.The mean amount of bone cement injected was(4.56±2.25)mUpoint.In the 40 patients,the preoperative and the postoperative one-week,one-month and 3-month VAS score were(8.00±0.85)points,(2.05±0.96)points,(2.08±0.94)points and(2.18±0.84)points respectively,the difference in VAS score between preoperative value and postoperative one-week value was statistically significant(P＜0.01).In 37 patients,the postoperative 6-month VAS score was(2.35±0.54)points;and in 28 patients,the postoperative 12-month VAS score was(2.43±0.79)points.The differences in VAS score between postoperative one-week value and postoperative one-month,3-month,6-month,and 12-month values were not statistically significant(all P＞0.05),while the differences in VAS score between preoperative value and postoperative values were statistically significant(F=316.3,P＜0.01).The postoperative 3-month,6-month,and 12-month local control rates were 96.49％,85.19％,and 78.12％respectively,the differences between each other among the above three values were statistically significant(P=0.026).No statistically significant differences in the proportion of using systemic anti-tumor therapy,the lesion size and the amount of bone cement injected existed between the controlled group and the progression group(all P＞0.05).The cement filling ratio in the controlled group and the progression group was(81.26±9.17)％and(68.40±12.98)％respectively,and the difference between the two groups was statistically significant(P＜0.01).Conclusion For the treatment of pelvic metastases,CT-guided POP is clinically safe and effective.The injected bone cement can control the progression of local lesions for a longer time.(J Intervent Radiol,2023,32:1197-1201)

Recontorno de sorriso gengival utilizando piezocirurgia pela técnica flapless ­ relato de caso / Gengival smile contouring using piezosurgery through the flapless technique ­ case report / Contorno de sonrisa gengival mediante piezocirugía a través de la técnica flapless ­ reporte de caso

A cirurgia plástica gengival tem sido cada vez mais procurada por pacientes que se apresentam descontentes com o seu sorriso. O procedimento convencional realizado é feito através de uma elevação de retalho para exposição de tecido ósseo e subsequente a osteotomia ou osteoplastia, o qual leva a necessidade de suturas e uma recuperação mais demorada. Com o avanço da tecnologia, a técnica cirurgia Flapless, conhecida como minimamente invasiva e indolor, onde trás uma recuperação mais favorável e com resultados satisfatórios. Tem como principal indicação para pacientes com biotipo periodontal fino e intermediário, o planejamento cirúrgico deve ser feito com exames complementares, como a tomografia, para poder ser calculado a quantidade de tecido ósseo a ser removido. Após a excisão do tecido gengival sem abertura de retalho, a osteotomia/osteoplastia é feito via sulco gengival com a utilização do ultrassom piezoelétrico. Evidencias clínicas e científicas mostram que a técnica Flapless possui resultados satisfatórios em um menor espaço de tempo, sem necessidade de suturas e melhor pós-operatório.

Gingival plastic surgery has been increasingly sought after by patients who are dissatisfied with their smile. The conventional procedure performed is done through a flap elevation to expose bone tissue and subsequent osteotomy or osteoplasty, which leads to the need for sutures and a longer recovery. With the advancement of technology, the Flapless surgery technique, known as minimally invasive and painless, brings a more favorable recovery and satisfactory results. Its main indication for patients with thin and intermediate periodontal biotype, surgical planning should be done with complementary exams, such as tomography, in order to calculate the amount of bone tissue to be removed. After excision of the gingival tissue without opening a flap, the osteotomy/osteoplasty is performed via the gingival sulcus using piezoelectric ultrasound. Clinical and scientific evidence shows that the Flapless technique has satisfactory results in a shorter period of time, without the need for sutures and better postoperative period.

Percutaneous-Reinforced Osteoplasty: A Review of Emerging Treatment Strategies for Bone Interventions.

Percutaneous-reinforced osteoplasty is currently being investigated as a possible therapeutic procedure for fracture stabilization in high-risk patients, primarily in patients with bone metastases or osteoporosis. For these patients, a percutaneous approach, if structurally sound, can provide a viable method for treating bone fractures without the physiologic stress of anesthesia and open surgery. However, the low strength of fixation is a common limitation that requires further refinement in scaffold design and selection of materials, and may potentially benefit from tissue-engineering-based regenerative approaches. Scaffolds that have tissue regenerative properties and low inflammatory response promote rapid healing at the fracture site and are ideal for percutaneous applications. On the other hand, preclinical mechanical tests of fracture-repaired specimens provide key information on restoration strength and long-term stability and enable further design optimization. This review presents an overview of percutaneous-reinforced osteoplasty, emerging treatment strategies for bone repair, and basic concepts of in vitro mechanical characterization.

Does Femoral Osteoplasty Improve Long-term Clinical Outcomes and Survivorship of Hip Arthroscopy? A 15-Year Minimum Follow-up Study.

BACKGROUND: Although femoral osteoplasty is common practice in treating cam-type femoroacetabular impingement (FAI), long-term data are lacking that support the ability of this procedure to optimize outcomes and alter natural history. PURPOSE: To compare long-term clinical outcomes and survivorship of treatment for symptomatic FAI via arthroscopic correction of labral or chondral pathology with and without femoral osteoplasty. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: A retrospective cohort study was performed across 2 consecutive cohorts of patients with isolated cam-type FAI who underwent hip arthroscopic treatment of labral or chondral pathology without femoral osteoplasty (HS group) or with femoral osteoplasty (HS-OST group). These unique cohorts were established at a distinct transition time in our practice before and after adoption of femoral osteoplasty for treatment of FAI. Clinical outcomes were measured using the modified Harris Hip Score (mHHS). Kaplan-Meier analysis was used to assess for total hip arthroplasty (THA)-free and reoperation-free survivorship. RESULTS: The final HS group included 17 hips followed for 19.7 ± 1.2 years, and the final HS-OST group included 23 hips followed for 16.0 ± 0.6 years. No significant patient or morphological differences were found between groups. Compared with the HS group, the HS-OST group had significantly higher final mHHS (82.7 vs 64.7 for HS-OST vs HS, respectively; P = .002) and mHHS improvement (18.4 vs 6.1; P = .02). The HS-OST group also had significantly greater 15-year THA-free survivorship versus the HS group (78% vs 41%, respectively; P = .02) and reoperation-free survivorship (78% vs 29%; P = .003). CONCLUSION: This study demonstrated superior long-term clinical outcomes and survivorship with combined arthroscopy and femoral osteoplasty compared with hip arthroscopy alone. These long-term data strongly support the practice of femoral osteoplasty in patients with cam FAI morphologies and suggest that this treatment alters the natural history of FAI at long-term follow-up.

Combining gantry-free cone-beam computed tomography with iterative metal artefact reduction for surgical follow-up imaging of the appendicular skeleton.

PURPOSE: Post-surgical evaluation of osteosynthesis material and adjacent tissue can be challenging in both radiography and cross-sectional imaging. This study investigates the performance of a multi-purpose X-ray scanner with cone-beam CT (CBCT) function and iterative metal artefact reduction capabilities in patients after osteoplasty of the appendicular skeleton. METHOD: Eighty individuals who underwent both conventional X-ray imaging and CBCT after osteoplasty of the hand/wrist (48), elbow (14), or ankle/foot (18) with the gantry-free twin robotic system were retrospectively enrolled. Radiological reports from clinical routine for both imaging modalities were retrospectively analyzed and compared with consensus expert reading by two musculoskeletal specialists serving as the standard of reference. Findings of screw dislocation or implant loosening, fragment displacement, and delayed healing were compared between X-ray and CBCT reports using the McNemar test. RESULTS: The median dose-area-product of CBCT and X-ray scans amounted to 27.98 and 0.2 dGy*cm2, respectively. Diagnostic accuracy for screw dislocation was superior in CBCT compared to standard radiograms (98.8 % vs 83.8 %; p = 0.002). Implant loosening (98.8 % vs 86.3 %; p = 0.006), fragment displacement (98.8 % vs 85.0 %; p < 0.001), and delayed healing (97.5 % vs 88.8 %; p = 0.016) were also more reliably detected in CBCT. Employing CBCT, postoperative complications were detected with a sensitivity and specificity of at least 95.8 % and 98.1 %, compared to 33.3 % and 92.86 % in radiography. CONCLUSIONS: With superior accuracy for various osteoplasty-related complications, the CBCT scan mode of a gantry-free twin robotic X-ray system with iterative metal artefact reduction aids post-surgical assessment in the appendicular skeleton.

Percutaneous osteoplasty in long bones: Current status and assessment of outcomes.

Osteoplasty is a minimally invasive imaging-guided intervention providing mechanical stabilization, bone consolidation and pain relief in oncologic patients presenting with non-osteoblastic bone metastases or with insufficiency fractures. The intervention relies on the injection of an acrylic substance (ie, polymethylmethacrylate; PMMA) into the target bone. PMMA is very resistant to axial compressive loads but much less to bending, torsional and shearing stresses. Accordingly, from a biomechanical standpoint osteoplasty is adapted for the palliative treatment of small painful lytic bone defects located in the epiphyseal region of long bones in patients with clear surgical contraindications; or for increasing the anchoring of the osteosynthesis material into the target bone. Although pain relief is rapid and effective following osteoplasty, secondary fractures have been reported in up to 8-9% of long bone tumors undergoing such intervention; and following such event, fixation with endomedullary osteosynthetic material (eg, nailing) is not practicable any more. Accordingly, careful patients' selection is critical and should happen with a multidisciplinary approach.

Avoiding complications in percutaneous osteoplasty.

Percutaneous osteoplasty techniques include cement injection either solely performed or in combination to hardware such as cannulated screws, peek implants or other metallic hardware including micro-needles and Kirschner wires. Depending on bone and local forces applied, fracture and osseous defect characteristics as well as symptoms and operator's preference percutaneous osteoplasty techniques include cementoplasty, fixation by internal cemented screw and augmented osteoplasty. Literature data support efficacy and safety of these techniques, focusing mainly on the minimal invasive nature of these approaches along with minimum overall morbidity and mortality and an impressive pain reduction effect. Percutaneous osteoplasty techniques in the peripheral skeleton are indicated for pain palliation or for prevention of impeding pathologic fractures. Although safe, osteoplasty techniques are not without risk of complications and adverse events. Complications are classified based either upon clinical impact or timing of occurrence; complications' reviewing and grading should be performed on terms of a uniform and accurate reproducible and validated categorization system. Significant factors for avoiding complications in percutaneous osteoplasty techniques include proper training, patient- and lesion-tailored approach, high-quality imaging guidance, sterility as well as appropriate selection of technique and materials. The present article reports the possible complications of percutaneous osteoplasty techniques and reviews the prerequisites necessary for avoiding and managing these adverse events.

Image guidance in osteoplasty and fixation.

Oncology patients, particularly those with breast, colorectal, prostate, renal and pancreatic cancers, are living longer due to advances in detection, and treatment. Unfortunately, this has come with a commensurate increase in the prevalence of osseous metastases and skeletal related events approaching 100,000 new patients each year. Patients are now experiencing serious morbidity and mortality due to pathologic fractures, altered structural mechanics, and cancer related bone pain. This patient population poses challenges for conventional open surgical and/or medical management often due to disease extent, location, and, in general, poor surgical candidacy. Percutaneous techniques may also be challenging under image guidance due to limited ability to use traditional orthopedic corridors, loss of cortical landmarks with destructive lesions, and need for live image guidance. Modern angiography suites with cone beam computed tomography (CBCT) and advanced imaging applications including needle guidance, 3D fusion, tumor segmentation, and angio-CT have facilitated the development of novel minimally invasive techniques for pain palliation and stabilization. The interventional radiologist is uniquely positioned to harness these advanced imaging applications and offer effective, safe, minimally invasive treatment options to patients with neoplastic disease within the axial, and appendicular skeletons. The focus of this article is to address the technical aspects of patient preparation, positioning, advanced imaging system capabilities, guidance strategies, and pitfalls during osteoplasty and fixation procedures.

A Holistic Approach for the Identification of Success Factors in Secondary Cleft Osteoplasty.

Cleft lip and palate belong to the most frequent craniofacial anomalies. Secondary osteoplasty is usually performed between 7 and 11 years with the closure of the osseus defect by autologous bone. Due to widespread occurrence of the defect in conjunction with its social significance due to possible esthetic impairments, the outcome of treatment is of substantial interest. The success of the treatment is determined by the precise rebuilding of the dental arch using autologous bone from the iliac crest. A detailed analysis of retrospective data disclosed a lack of essential and structured information to identify success factors for fast regeneration and specify the treatment. Moreover, according to the current status, no comparable process monitoring is possible during osteoplasty due to the lack of sensory systems. Therefore, a holistic approach was developed to determine the parameters for a successful treatment via the incorporation of patient data, the treatment sequences and sensor data gained by an attachable sensor module into a developed Dental Tech Space (DTS). This approach enables heterogeneous data sets to be linked inside of DTS, archiving and analysis, and is also for future considerations of respective patient-specific treatment plans.

Increased range of motion but otherwise similar clinical outcome of arthroscopy over open osteoplasty for femoroacetabular impingement at midterm follow-up: A systematic review.

BACKGROUND: A systematic review was conducted comparing patient reported outcomes measures (PROMs), functional scores, and the rate of complications between arthroscopic and open treatment for femoroacetabular impingement (FAI) at mid-term follow-up. MATERIAL AND METHODS: This systematic review was performed according to the PRISMA guidelines. The literature search was performed in October 2020. All clinical trials treating FAI using open osteoplasty or arthroscopic surgery were considered for inclusion. Only articles reporting >12 months follow-up were included. RESULTS: Data from 97 articles (9981 procedures) were collected. At a mean 19.2 months follow-up there was no difference between the two cohorts. At a mean follow-up of 38 months, the external rotation was increased in the arthroscopic group (P < 0.0001). The modified Harris Hip Score scored greater in favour of the open osteoplasty group (P = 0.04), as did the Hip Outcome Score - Activities of Daily Living subscale (P = 0.01). At a mean 45.1 months the arthroscopic group presented greater external rotation (P < 0.0001) and SF-12 Mental (P = 0.04). The modified Harris Hip Score was greater in favour of the open osteoplasty group (P = 0.03), as was the HOS-ADL (P = 0.01). Regarding complications, the arthroscopic group experienced lower rates of subsequent revisions (P < 0.0001). CONCLUSION: Based on the significant reduction of revisions-rate and significant increase in range of motion, arthroscopy treatment for the management of FAI may be recommended.
