Abstract Background: To evaluate the clinical and radiographic outcomes after ulrasonography guided Closed reduction in the treatment of displaced transphyseal fracture of the distal Humerus (TFDH).Methods: Twenty-seven patients with displaced TFDH successfully treated by the ulrasonography guided closed reduction during January 2012 to December 2016 were retrospective reviewed. After mean follow-up of 34.88 months, the clinical and radiographic outcomes of patients were evaluated. The cubitus varus of the affected elbow were also assessed at latest follow-up.Results: The successful rate of ultrasonography guided closed reduction in the treatment of displaced TFDH was 84% (27/32). The twenty-seven patients with successful reduction were included for the following analysis. There were 20 male patients and 7 female patients included the study and the mean age at treatment was 15.39±3.10 months, seventeen fractures occurred in right side elbow and ten in left side. At the last follow-up, there were significant decreases in the elbow flexion (3°, P=0.027) and range of motion (5°, P=0.003) between the injured and uninjured elbow, respectively. Whereas no difference in elbow extension was detected (P=0.110). Flynn’s criteria assessment showed that all the patients achieved excellent or good outcomes both in the functional and cosmetic categories. The clinical and radiographic carrying angle at the last follow-up were 11.67 ± 3.11° and 10.46 ± 3.88°, respectively. And the incidence of cubitus varus after treament was 7.4% at last follow-up.Conclusion: The ultrasonography guided closed reduction in the treatment of displaced TFDH is an effective procedure, the adequate fracture reduction can be acquired with the advantages of real-time, non-radioactive, and simple utilization. With the percutaneous pining fixation, satisfactory clinical and radiographic outcomes can be achieved with low incidence of postoperative cubitus varus.

Objectives: To assess closed reduction by Baumann angle in supracondylar fractures humerus treated by closed reduction andpercutaneous pinning. Material and Methods: This prospective study of 50 patients who presented with displaced supracondylar fracture ofhumerus in children between ages 1-12 years were admitted to Orthopedic and Trauma unit of Hayatabad Medical Complex Peshawar overperiod from January 2008 to July 2009. Closed reduction and percutaneous pinning were performed under general anesthesia and postoperativereduction was assessed by Baumann angle. All patients were followed for one year. Results: Mean age of the patients was 7.02 years± 2.25 SD. Loss of Baumann angle in injured side was range from 2O to 8O. Loss of carrying angle in injured side was range from 3O to 9O. WhenBaumann angle and carrying angle of both sides were compared the mean Baumann angle loss and carrying angle loss were 5.360 ± 2.22 SDand 4.320 ± 1.52 SD respectively. Using Flynn’s criteria 36 (72%) patients out of 50 patients with carrying-angle loss considered to be excellentresults and 14(28%) good results. Neither of the patient developed cubitus varus deformit y after one year of follow-up. Conclusions: Baumannangle of the humerus is a simple and reliable measurement of closed reduction that can be used to predict final carrying angle in supracondylarhumeral fractures in children.

Background: Consensus on method of treatment of displaced supracondylar fracture of the humerus in children is still lacking. Purpose of this prospective randomized controlled study is to compare closed reduction and long arm slab application with closed reduction and percutaneous crossed Kirschner wires fixation. Materials and methods: Children of age less than 12 years presented in B.P. Koirala institute of health sciences, Dharan in one year were randomly allocated to group A and group B consisting 30 patients in each group. Closed reduction and long arm posterior slab was applied in group A and in group B, closed reduction was followed by crossed Kirschner wires fixation. Clinical and radiological evaluation of reduction was performed immediately after procedure and at the end of first week, third week, third month and sixth month. Results: The groups were matched for pre fracture characteristics and post reduction evaluation. The mean follow up period in group A was 6.9 months and in group B was 7.1 months. Closed reduction failed in two patients at the first attempt and one patient failed to retain reduction at first week in group A. 11 patients (5 in group A and 6 in group B) were lost to follow up. Range of movement, valgus, varus and carrying angle of elbow in two groups were not significantly different. The mean difference of carrying angle of affected elbow as compare to normal elbow was significant in group A (p ? 0.05). Flynn's overall rating showed 32% excellent, 36% good, 18% fair and14 % poor result in patents treated with long arm slab as compared to 58% excellent, 29% good, 13 % fair and no poor results in patients with crossed Kirschner wires fixation. Conclusion: The outcome of displaced extension type supracondylar fracture of the humerus in children, managed with closed reduction and slab application are comparable with closed reduction and crossed Kirschner wire fixation in terms of range of motion but is inferior in restoration of carrying angle. Good to excellent cosmetic and functional results are higher with crossed percutaneous Kirschner wires fixation than with slab immobilization.

Ulnar Lengthening

Abstract Background Gradual ulnar lengthening is the most commonly used procedure in the treatment of Masada type I/II deformity in patients with hereditary multiple osteochondromas. However, the treatment remains controversial for the recurrence of deformity in growing children. This study aims to evaluate the clinical and radiological outcomes of ulnar gradual lengthening in our clinic. Methods We retrospectively reviewed patients who underwent ulnar lengthening by distraction osteogenesis from June 2008 to October 2017. The carrying angle (CA) and range of motion (ROM) of the forearm and elbow were clinically assessed, and the radial articular angle (RAA) and ulnar shortening (US) were radiologically assessed before lengthening, 2 months after external frame removal, and at the last follow-up. Results The current study included 15 patients (17 forearms) with a mean age of 9.4 ± 2.3 years at the index surgery. The mean follow-up period was 4.2 ± 2.4 years. There were 9 patients (10 forearms) with Masada type I deformity and 6 patients (7 forearms) with Masada type IIb deformity. The mean amount of ulnar lengthening was 4.2 ± 1.2 cm. The mean RAA improved from 37 ± 8 to 30 ± 7° initially (p = 0.005) and relapsed to 34 ± 8° at the last follow-up (p = 0.255). There was a minimal deterioration of US yet significant improvement at the last follow-up compared to pre-op (p < 0.001). At the last follow-up, the mean forearm pronation and elbow flexion increased significantly (p < 0.001 and p = 0.013, respectively), and the mean carrying angle also improved significantly (p < 0.001). No patient with type IIb deformity achieved a concentric radial head reduction. Conclusions Gradual ulnar lengthening significantly reduces cosmetic deformity and improves function in patients with Masada type I/IIb deformity. Our results supported early ulnar lengthening for patients with a tendency of dislocation of the radial head.

Abstract Background Gradual ulnar lengthening is the most commonly used procedure in treatment of Masada type I/II deformity in patients with hereditary multiple osteochondromas. However, the treatment remains controversial for the recurrence of deformity in growing children and only slightly handicapped of daily life activities in untreated adult patients. The aim of this study was to evaluate mid-term clinical and radiological outcomes of ulnar gradual lengthening in our clinic. Methods We retrospectively reviewed patients who underwent ulnar lengthening by distraction osteogenesis from June 2008 to October 2017. Patients with less than two years of follow-up were excluded. The surgical procedures consisted of ulnar lengthening by external fixator and/or excision of the osteochondroma at the distal ulna. The carrying angle (CA) and range of motion (ROM) of the forearm and elbow were clinically assessed, and the radial articular angle (RAA) and ulnar shortening (US) were radiologically assessed before lengthening, two months after external frame removal, and at the last follow-up. Results The current study included 15 patients (17 forearms) with a mean age of 9.4 ± 2.3 years at index surgery. The mean follow-up period was 4.2 ± 2.4 years. There were 9 patients (10 forearms) with Masada type I deformity and 6 patients (7 forearms) with Masada type IIb deformity. The mean amount of ulnar lengthening was 4.2 ± 1.2 cm. The mean RAA improved from 37.3 ± 7.9° to 29.8 ± 6.5° initially (P = 0.003) and relapsed to 34.4 ± 7.6° at the last follow-up (p = 0.234). There was minimal deterioration of US yet significant improvement at the last follow-up compared to pre-op (p < 0.001). The elbow flexion and forearm pronation were improved significantly at last follow-up (p < 0.001 and p = 0.024, respectively). The mean carrying angle improved significantly from − 6.3 ± 7.4 ° preoperatively to 7.4 ± 11.1° at last follow-up (p < 0.001). Conclusions Gradual ulnar lengthening significantly reduces cosmetic deformity and improves function; it is recommended for patients with Masada type I/IIb deformity. Therefore, we advocated aggressive individual treatment protocol for patients with Masada type I/IIb deformities.

OBJECTIVEHuman acellular nerve allograft applications have increased in clinical practice, but no studies have quantified their influence on reconstruction outcomes for high-level, greater, and mixed nerves, especially the brachial plexus. The authors investigated the functional outcomes of human acellular nerve allograft reconstruction for nerve gaps in patients with brachial plexus injury (BPI) undergoing contralateral C7 (CC7) nerve root transfer to innervate the upper trunk, and they determined the independent predictors of recovery in shoulder abduction and elbow flexion.METHODSForty-five patients with partial or total BPI were eligible for this retrospective study after CC7 nerve root transfer to the upper trunk using human acellular nerve allografts. Deltoid and biceps muscle strength, degree of shoulder abduction and elbow flexion, Semmes-Weinstein monofilament test, and static two-point discrimination (S2PD) were examined according to the modified British Medical Research Council (mBMRC) scoring system, and disabilities of the arm, shoulder, and hand (DASH) were scored to establish the function of the affected upper limb. Meaningful recovery was defined as grades of M3–M5 or S3–S4 based on the scoring system. Subgroup analysis and univariate and multivariate logistic regression analyses were conducted to identify predictors of human acellular nerve allograft reconstruction.RESULTSThe mean follow-up duration and the mean human acellular nerve allograft length were 48.1 ± 10.1 months and 30.9 ± 5.9 mm, respectively. Deltoid and biceps muscle strength was grade M4 or M3 in 71.1% and 60.0% of patients. Patients in the following groups achieved a higher rate of meaningful recovery in deltoid and biceps strength, as well as lower DASH scores (p < 0.01): age < 20 years and age 20–29 years; allograft lengths ≤ 30 mm; and patients in whom the interval between injury and surgery was < 90 days. The meaningful sensory recovery rate was approximately 70% in the Semmes-Weinstein monofilament test and S2PD. According to univariate and multivariate logistic regression analyses, age, interval between injury and surgery, and allograft length significantly influenced functional outcomes.CONCLUSIONSHuman acellular nerve allografts offered safe reconstruction for 20- to 50-mm nerve gaps in procedures for CC7 nerve root transfer to repair the upper trunk after BPI. The group in which allograft lengths were ≤ 30 mm achieved better functional outcome than others, and the recommended length of allograft in this procedure was less than 30 mm. Age, interval between injury and surgery, and allograft length were independent predictors of functional outcomes after human acellular nerve allograft reconstruction.

Objective The purpose of the current study is to evaluate the clinical and radiographic outcomes at early to midterm follow-up between fresh precut cores versus hemi-condylar osteochondral allograft (OCAs) in the treatment of symptomatic osteochondral lesions. Design A retrospective review of patients who underwent an OCA was performed. Patient matching between those with OCA harvested from an allograft condyle/patella or a fresh precut allograft core was performed to generate 2 comparable groups. The cartilage at the graft site was assessed with use of a modified Magnetic Resonance Observation of Cartilage Repair Tissue (MOCART) scoring system and patient-reported outcomes were collected. Results Overall, 52 total patients who underwent OCA with either fresh precut OCA cores ( n = 26) and hemi-condylar OCA ( n = 26) were pair matched at a mean follow-up of 34.0 months (range 12 months to 99 months). The mean ages were 31.5 ± 10.7 for fresh precut cores and 30.9 ± 9.8 for hemi-condylar ( P = 0.673). Males accounted for 36.4% of the overall cohort, and the mean lesion size for fresh precut OCA core was 19.6 mm2 compared to 21.2 mm2 for whole condyle ( P = 0.178). There was no significant difference in patient-reported outcomes including Visual Analogue Scale, Knee Injury and Osteoarthritis Outcome Score for Joint Replacement, and Tegner ( P > 0.5 for each), or in MOCART score (69.2 vs. 68.3, P = 0.93). Conclusions This study found that there was no difference in patient-reported clinical outcomes or MOCART scores following OCA implantation using fresh precut OCA cores or size matched condylar grafts at early to midterm follow-up.

Aim: To compare the clinical and radiographic outcomes observed in Necrotic Immature Permanent Teeth (NIPT) after revascularization or apexification with MTA-apical plug. Methodology: PubMed/MEDLINE, Web of science and Scopus were the databases used, up to July 30th, 2017, for article research. Independent reviewers read the titles and abstracts of all reports that met inclusion/exclusion criteria: prospective or retrospective clinical studies comparing the revascularization of root canal and apexification. Clinical success of therapies, deposition and thickening of lateral dentinal walls (root width) and the continuation of root development (root length) were investigated. Bias risk of included studies was assessed using the Cochrane risk of bias. Results: From 1642 records, five papers fulfilled all inclusion criteria. Overall, 91 teeth were submitted to revascularization and 64 teeth to apexification with MTA. The mean follow-up was 23.2 months in revascularization and 21.8 in apexification. Clinical success rate was of 87.9% in the revascularization group and 90.6% in the apexification group. An increase on lateral dentinal walls thickening was observed in most revascularization cases (13%) while MTA as apical plug suggest a mild resorption of the root (1.3%). High bias risk was observed on included studies. Conclusions: Apexification with MTA-apical plug provides similar clinical success to revascularization. However, radiographic measurements showed an improvement in thickening of lateral dentinal walls in most of the revascularization cases in addition to a higher dental development. However, these results should be interpreted with caution.

Background: Several osteotomies have been described for the correction of acetabular dysplasia associated with variable outcomes. The purpose of our study was to evaluate the effect of Dega transiliac osteotomy in radiological correction of acetabular dysplasia by assessing the change in various radiological parameters from preoperative period to postoperative period and at a follow up of two years.Methods: This was a prospective observational study conducted on 35 patients of either sex, in the age range of 18 months to 8 years, presenting to the paediatric orthopaedic OPD, of Artemis Health Institute, Gurgaon, Haryana, India between January 2012 and September 2014 in whom a diagnosis of acetabular dysplasia was made. All the patients underwent Dega transiliac osteotomy and the effectiveness of this osteotomy in the correction of acetabular dysplasia was assessed by measuring various radiological parameters preoperatively, postoperatively, and at a follow up of two years. The various radiological parameters included acetabular index (AI), centre edge angle of wiberg (CEAW), reimer’s extrusion index (REI) and the shenton’s line (SL).Results: In present study sample of 35 cases, 29 had DDH, 4 were secondary to cerebral palsy and 2 had developed dysplasia following septic arthritis of the hip. The sex distribution showed 19 females and 16 male patients. All the patients underwent Dega transiliac osteotomy at a mean age of 42.94±21.68 months. The mean value of AI improved from 42.43±4.77 degrees in preoperative period to 19.86±2.45 degrees at follow up. The mean value of CEAW improved from - 32.49±21.60 degrees in preoperative period to 32.06±5.48 degrees at follow up. The mean value of REI, improved from 91.06±21.43 % in preoperative period to 0.29±1.18 % at follow up. The SL was broken in all the 35 patients preoperatively, while at follow up it was continuous in all the patients. These changes in all the four parameters were statistically highly significant (p value<0.001).Conclusions: Thus results of present study demonstrate that Dega osteotomy is a safe, effective and versatile surgical procedure for the treatment of acetabular dysplasia secondary to DDH and other disorders. Since the majority of the patients included in this study had the diagnosis of DDH, the results of this study are more representative of dysplasia associated with DDH.

Abstract Objective: To explore the clinical efficacy of treating a first metacarpal base fracture by closed reduction and percutaneous parallel K-wire interlocking fixation between the first and second metacarpals.Methods: Twenty patients treated by the above technique from October 2015 to December 2018 at our institution were retrospectively reviewed. The patients’ average age was 36 years (range, 16–61 years). Eleven patients were extra-articular fractures and nine were intra-articular fractures. The mean follow-up period was 12 months (range, 10–18 months). At the final follow-up, the functional recovery of the injured hand was assessed and compared with that of the uninjured hand.Results: All patients recovered well with no complications. In the extra-articular fracture group, the mean hand grip strength, pinch strength, and Kapandji score were 43.4 ± 7.0 kg, 9.1 ± 1.4 kg, and 9.5 ± 0.7 on the injured side and 41.7 ±6.8 kg, 8.7 ± 0.8 kg, and 9.7 ± 0.5 on the uninjured side, respectively, with no significant differences. In the intra-articular fracture group, the above indexes were 43.0 ± 6.5 kg, 9.0 ± 1.1 kg, and 9.3 ± 0.7 on the injured side and 42.1 ± 6.6 kg, 8.6 ± 1.1 kg, and 9.7 ± 0.5 on the uninjured side, respectively, also with no significant differences. The abduction and flexion-extension arc of the thumb on the injured hand were lower than those on the uninjured hand in both the extra-articular and intra-articular fracture groups, but the patients felt clinically well with respect to daily activities and strength.Conclusion: The percutaneous parallel K-wire and the interlocking fixation technique is simple, effective, and economic for first metacarpal base fractures.
