ABSTRACT

Retroníquia é uma onicopatia inflamatória caracterizada pelo crescimento desordenado e empilhamento de lâminas ungueais, associados ao desequilíbrio na produção matricial de placas, que costumam se sobrepor. Este quadro pode estar associado a trauma, evoluindo com reação inflamatória junto à dobra ungueal proximal e formação de tecido de granulação. Relatamos o caso de um paciente com retroníquia no hálux esquerdo, submetido a tratamento cirúrgico após falhas de respostas terapêuticas a tratamentos clínicos prévios. A abordagem cirúrgica levou à avulsão das lâminas ungueais sobrepostas e à exérese de volumosos tecidos de granulação, com adequada evolução no pós-operatório


Retronychia is an inflammatory onychopathy characterized by the disordered growth and stacking of nail plates, associated with an imbalance in the matrix production of plaques, which tend to overlap. This condition may be associated with trauma, evolving with an inflammatory reaction along the proximal nail fold and granulation tissue formation. We report the case of a patient with retronychia in the left hallux, submitted to surgical treatment after failure of therapeutic responses with previous clinical treatments. The surgical approach led to the avulsion of the overlapping nail plates and the excision of voluminous granulation tissues, achieving adequate postoperative evolution.

ABSTRACT

Objective@#Conebeam CT (CBCT) was used to measure the palatine between the maxillary first and second molars. The proximal and distal palatal widths of the maxillary first and second molar and the palatal mucosal thickness and bone tissue thickness when microscrew implant anchorage nail were implanted at different angles provided a reference for the clinical selection of microscrew implant placement.@* Methods@#The image data of 90 adult patients were selected as the research object, and the jaw bone was reconstructed by scanning. In maxillary palatine, selection of distances at 12 mm, 14 mm, 16 mm, and 18 mm from the palatal apex of maxillary first molar between the maxillary first and second molar were used as measurement, measured the proximal and distal palatal widths of maxillary first and second molar and the palatal mucosal thickness and bone tissue thickness when microscrew implant anchorage nails were implanted at 30 °, 45 °, 60 °, and 90 °. SPSS 26.0 software was used for one-way ANOVA and LSD pair comparison. @*Results@#The larger the angle of the microscrew implant anchorage nail was, the smaller the proximal and distal medial widths between the maxillary first and second molar, and the difference was statistically significant (P < 0.05). Compared with the 90° direction, the proximal and distal medial widths of the microscrew implant anchorage nail were larger in the 60° direction. The greater the angle of implantation, the smaller the mucosal thickness and the greater the bone tissue thickness, and the results showed a significant difference (P < 0.001). Compared with the direction of 30° and 45°, the mucosal thickness at the direction of 60° was smaller, and the bone tissue thickness was larger. The higher the position of the microscrew implant anchorage nail, the greater the width of the proximal and distal medial, and the difference was statistically significant (P < 0.05). Compared with the positions 12 and 14 mm from the palatal tip, the proximal and distal medial widths of the microscrew implant anchorage nail were larger. The higher the implant position was, the greater the mucosal thickness and the smaller the bone tissue thickness. The results showed a significant difference (P < 0.001). Compared with the position of 18 mm from the palatal tip of the maxillary first molar, the mucosal thickness was smaller and the bone tissue thickness was larger.@*Conclusion@#It is most appropriate to implant microscrew implant anchorage nail at least 10 mm in length in the direction of 60° at the palatal apex 16 mm from the maxillary first molar in palatine between the first and second molar.

ABSTRACT

El síndrome de la uña verde o cloroniquia corresponde a la infección por Pseudomonas aeruginosa de una lámina ungueal dañada en pacientes con algún factor de riesgo identificable, siendo los más frecuentes la inmunosupresión, el ambiente húmedo constante y la patología ungueal preexistente. Su diagnóstico es relativamente sencillo si se logra observar la tríada característica de coloración verdosa de la lámina ungueal, paroniquia proximal crónica y onicolisis distal; en casos de duda diagnóstica se puede enviar una muestra de la uña afectada para cultivos o estudio histopatológico. El pilar de su tratamiento corresponde al uso de antibióticos tópicos o sistémicos en conjunto con medidas generales que protejan de la humedad. Es muy importante enfatizar la prevención de esta patología en el personal de salud, especialmente en el contexto del lavado de manos frecuente y riguroso implementado durante la pandemia COVID-19, ya que existen reportes de transmisión nosocomial de P. aeruginosa por profesionales de la salud con infección ungueal.(AU)


Green nail syndrome or chloronychia is the infection of a damaged nail plate by Pseudomonas aeruginosa in a patient with an identifiable risk factor; the most frequently described are immunosuppression, a persistent moist environment and preexisting nail disease. Its diagnosis is relatively simple if the characteristic triad of green discoloration of the nail plate, chronic proximal paronychia and distal onycholysis can be observed, in cases of doubt a sample of the affected nail can be sent for cultures or histopathology. The cornerstone of treatment is the use of topical or systemic antibiotics along with measures to protect the nail from moisture. Prevention of this disease must be emphasized in health care personnel, especially in the context of frequent and rigorous handwashing practices implemented during the COVID-19 pandemic, since there are reports of nosocomial transmission of P. aeruginosaby health care professionals with nail infection.(AU)

ABSTRACT

The aim of this study was to evaluate the association of oral parafunctions with the presence of signs and symptoms of craniomandibular disorder in children with cleft lip and palate (CLP). A cross-sectional study was performed in which one hundred and eighty-eight children with CLP and absence of associated syndromes or malformations were investigated. During clinical examination, the presence of wear facets and dental occlusion were observed and palpation was performed in the temporomandibular joint region (TMJ) and orofacial musculature . The children and their guardians were interviewed regarding the presence of oral parafunctional habits (bruxism, the act of biting the lips and/or cheeks, nail biting, sucking of fingers and pacifiers) and signs and symptoms of craniomandibular dysfunction (headache, ear and/or neckache, tiredness or crack in the TMJ during mouth opening and chewing movements). The data were analyzed by means of absolute and relative frequency measurements, and bivariate analysis using Pearson's chi-square test and likelihood ratio test were performed, considering the significance level of 5%. A higher prevalence of cleft lip and palate type (76.0%) and the presence of malocclusion (61.7%) was observed, highlighting the anterior crossbite (58.7%) and midline deviation (48.9%). There was a higher occurrence of teeth grinding (40.4%), onychophagy (28.7%) and biting lips and/or cheeks (28.7%). Onychophagia was associated with headache (p <0.05) and with pain or cracking during mouth opening (p <0.05). It was concluded that parafunctional oral habits may be associated with signs and symptoms of craniomandibular disorder in children with cleft lip and palate.


O objetivo do estudo foi avaliar a associação de parafunções orais com sinais e sintomas da disfunção craniomandibular em crianças com fissuras labiopalatinas (FLP). Um estudo transversal foi realizado, no qual cento e oitenta e oito crianças com FLP e ausência de síndromes ou malformações associadas, foram investigadas. Durante exame clínico, a presença de facetas de desgaste e a oclusão dentária foram observadas e foi realizada a palpação na região da articulação temporomandibular (ATM) e musculatura orofacial. As crianças e seus responsáveis foram entrevistados com relação à presença de hábitos orais parafuncionais (bruxismo, ato de morder os lábios e/ou bochechas, onicofagia, sucção de dedos e de chupeta) e sinais e sintomas de disfunção craniomandibular (cefaléia, ouvido, dor, cansaço ou estalo na ATM durante movimentos de abertura bucal e de mastigação). Os dados foram analisados por meio de medidas de frequência absoluta e relativa e a análise bivariada foi realizada por meio dos testes do Qui-quadrado de Pearson (χ2) e a Razão de verossimilhança, considerando o nível de significância de 5%. Uma maior prevalência das fissuras envolvendo lábio e palato (76,0%) e presença de maloclusão (61,7%) foi observada, com destaque para mordida cruzada anterior (58,7%) e desvio de linha média (48,9%). Houve uma maior ocorrência do ato de ranger os dentes (40,4%), da onicofagia (28,7%) e do hábito de morder lábios e/ou bochechas (28,7%). A onicofagia foi associada à cefaléia (p<0,05) e à dor ou estalo durante abertura bucal (p<0,05). Conclui-se que hábitos orais parafuncionais podem estar associados a presença de sinais e sintomas da disfunção craniomandibular em crianças com FLP.

ABSTRACT

PURPOSE@#In the surgical treatment of paediatric forearm fractures, plate-screw and titanium elastic nails are used. During the transformation of ligamento-osseous structures from adolescence form into adult form, more stable fixation is required. The aim of this study was to evaluate the results of locked intramedullary nail fixation in adolescent forearm fractures.@*METHODS@#A retrospective examination was made on 36 adolescent patients who underwent surgery with locked intramedullary nail fixation due to a forearm fracture. The included patients were in the adolescent age group (12-17 years), did not meet conservative follow-up criteria and had unstable fractures (>10° angulation and 18 years or 15 years had prolonged time to union ([11.1 ± 1.8] weeks). There were no non-unions, re-fractures or infections. No complications were observed during implant removal. None of the patients had sensorial radial nerve injury or tendon damage.@*CONCLUSION@#The locked intramedullary nailing technique, which is minimally invasive and provides biological fixation, was found to be successful and safe in the treatment of adolescent forearm fractures.

ABSTRACT

Objective:To investigate dermoscopic manifestations and features of melanonychia.Methods:A retrospective analysis was carried out on dermoscopic images of 4 common types of melanonychia collected in Department of Dermatology, Xijing Hospital, the Fourth Military Medical University from January 2016 to July 2020.Results:A total of 266 cases of melanonychia were collected, including 64 (24.1%) of subungual melanoma, 52 (19.5%) of nail matrix nevi, 89 (33.5%) of subungual hemorrhage, and 61 (22.9%) of onychomycosis. Subungual melanoma and nail matrix nevi mostly occurred in the fingernails. To be specific, subungual melanoma most frequently occurred in the thumbnails (62.8%) , while nail matrix nevi mostly involved the 2 nd - 5 th fingernails (73.9%) . Subungual hemorrhage and onychomycosis mostly occurred in the toenails, and there were 51 (57.3%) cases of subungual hemorrhage of the toenails and 46 (75.4%) cases of onychomycosis of the toenails. Subungual melanoma mostly occurred in patients aged over 40 years (49 cases, 76.8%) , while the other 3 types of melanonychia mostly affected patients aged under 40 years. Dermoscopic manifestations of subungual melanoma mainly included regular longitudinal bands (35 cases, 54.7%) or irregular bands (25 cases, 39.0%) whose width was greater than 3 mm in 87.5% cases, Hutchinson sign (36 cases, 56.3%) , and ruptures (15 cases, 23.4%) which mainly were black-brown in color; dermoscopic manifestations of nail matrix nevi mainly were a single regular pigmented band (52 cases, 100%) whose width was less than 3 mm in 36 (69.2%) cases, and Hutchinson sign (26 cases, 50%) , while no ruptures were observed in nail matrix nevus lesions; subungual hemorrhage dermoscopically manifested as diffuse macules (74 cases, 83.1%) , and globular dark red or black hemorrhagic structures were observed in 85 (95.5%) cases; fungal melanonychia was dermoscopically characterized by irregular dark brown longitudinal bands (54 cases, 88.5%) . Conclusions:Subungual melanoma was dermoscopically characterized by regular longitudinal bands with a width of greater than 3 mm, nail matrix nevi by regular longitudinal bands, subungual hemorrhage by diffuse macules, and onychomycosis by irregular longitudinal bands. Dermatoscopy can be used to identify melanonychia lesions and provide a basis for auxiliary diagnosis of subungual melanoma.

ABSTRACT

In recent years, some progress has been made in the diagnosis and treatment of nail diseases, but there are still many challenges, such as longitudinal melanonychia, rare nail unit-specific tumors and nail dystrophy. Longitudinal melanonychia may develop into melanoma. Besides, biopsy and surgery are triggering factors for acral melanoma, so it is important to decide whether to operate and how to apply operating principles in clinic. In addition, the diagnosis and treatment should be based on patients′ age, clinical evaluation results, dermoscopic findings and pathological examinations, so as to avoid missed diagnosis of malignant melanonychia and deformities from treatment of benign melanonychia as far as possible. There are few summaries of clinical manifestations and pathological features of rare nail unit-specific tumors, and their diagnosis is difficult. In particular, onychocytic carcinoma and onycholemmal carcinoma are malignant tumors with great harm, so this article focuses on the two kinds of tumors to remind clinicians to avoid missed diagnoses. The etiology of nail dystrophy is complex. Nail dystrophy caused by inflammatory diseases can be treated with topical or systemic drugs, while various nail deformities caused by genetic factors, toe deformities, improper walking posture, mechanical injuries, and chronic inflammation of the nail groove are in need of physical or surgical correction. This article gives insight into challenges and strategies for the diagnosis and treatment of the above nail diseases.

ABSTRACT

Objective:To evaluate the efficacy of complete nail plate avulsion in the treatment of retronychia.Methods:From June 2018 to November 2019, 5 patients with retronychia (5 toes) were collected from the Department of Dermatology, Shanghai Ninth People′s Hospital, Shanghai JiaoTong University School of Medicine, and treated with complete nail plate avulsion. In some cases, redundant skin tissues at the distal end of the great toe were removed. After the surgery, artificial nails were placed on the surface of the nail bed followed by the suturing.Results:In the 5 patients, the neonatal nail plate gradually grew over the nail bed, and pain was completely relieved. Within the follow-up of 6-12 months, the nail plates of the 5 patients all returned to normal.Conclusion:Complete nail plate avulsion is effective for the treatment of retronychia, and worthy of clinical promotion.

ABSTRACT

Objective:To compare the efficacy between Multiloc humeral intramedullary nail system (Multiloc) and proximal humerus internal locking system (PHILOS) in the treatment of adult proximal humeral fractures.Methods:A retrospective analysis was conducted of the 83 adult patients with proximal humeral fracture who had been treated at Trauma Center, The Second People's Hospital of Changzhou from August 2018 to March 2021. They were 33 males and 50 females, with 45 left sides and 38 right sides injured. By the Neer classification, there were 48 two-part, 22 three-part and 13 four-part fractures. The patients were assigned into 2 groups according to different treatments: an observation group ( n=41) receiving treatment by Multiloc and a control group ( n=42) receiving treatment by PHILOS. The 2 groups were compared in terms of humeral neck shaft angles and visual analogue scale (VAS) pain scores preoperation and one month postoperation, Neer shoulder function score at the last follow-up, and incidence of adverse reactions. Results:The preoperative general data showed no statistically significant differences between the 2 groups, indicating the groups were comparable ( P>0.05). The humeral neck shaft angle (127.4°±3.6°) was recovered significantly better and the VAS pain score (1.3±0.3) was significantly lower in the observation group than in the control group (129.6°±4.5°,2.1±0.3) one month after operation ( P<0.05). The excellent to good rate by Neer score at the last follow-up (90.24%, 37/41) was significantly higher and the incidence of adverse reactions (2.44%) significantly lower in the observation group than in the control group (71.43%, 30/42 and (19.05%, 8/42) ( P<0.05). Conclusion:In the treatment of adult proximal humeral fractures, compared with PHILOS, the Multiloc system is more effective in improving shoulder joint function, promoting shoulder motion recovery and reducing pain.

ABSTRACT

Objective:To compare the efficacy of minimally invasive percutaneous pedicle screw fixation combined with injured vertebra bone grafting (PPSF+BG) and simple percutaneous pedicle screw fixation (PPSF) in the treatment of single segmental thoracolumbar compression fracture.Methods:The data were analyzed retrospectively of the 56 patients who had undergone PPSE at Department of Spine Surgery, Wuhan Puren Hospital from February 2017 to May 2019. Of them, 29 were treated by PPSF+BG [17 males and 12 females with an age of (50.6±8.4) years] and 27 by simple PPSF [13 males and 14 females with an age of (49.3±8.2) years]. The 2 groups were compared in terms of operation time, intraoperative blood loss, hospital stay and incidence of complications. The height of anterior edge of injured vertebra, cobb angle of injured kyphosis, visual analogue scale (VAS) and Oswestry disability index (ODI) at postoperative 1, 6 and 12 months were also compared between the 2 groups.Results:There was no significant difference in the preoperative general data between the 2 groups, showing they were comparable ( P>0.05). All of them were followed up for more than 12 months. There was no significant difference between the 2 groups in operation time, intraoperative blood loss, hospital stay or incidence of complications ( P>0.05). There was no significant difference between the 2 groups either in the height of anterior edge of injured vertebra, cobb angle of injured kyphosis or ODI score at 1 or 6 months after operation ( P>0.05). At 12 months after operation, PPSF+BG group had a significantly greater height of injured vertebra [(19.5±0.9) mm], a significantly smaller cobb angle of kyphosis (7.1°±0.5°) and a significantly lower ODI score (11.1±2.9) than PPSF group [(18.2±1.3) mm, 8.1°±0.5° and 19.5±1.6] ( P<0.05). At postoperative 6 and 12 months, the VAS scores in PPSF+BG group were significantly lower than those in PPSF group ( P<0.05). In all the patients, the postoperative height of anterior edge of injured vertebra, cobb angle of injured kyphosis, VAS and ODI scores were significantly improved than the preoperative values ( P<0.05). Conclusion:Although both minimally invasive percutaneous pedicle screw fixation combined with bone grafting and simple percutaneous pedicle screw fixation can achieve good therapeutic outcomes for single segmental thoracolumbar compression fractures, the former may be superior in effectively promoting rapid recovery of the patients and improving the quality of life of the patients after operation.

ABSTRACT

Objective:To compare the efficacy between intramedullary nailing (IMN) and minimally invasive percutaneous pate oteosynthesis (MIPPO) in the treatment of distal tibial fractures.Methods:China National Knowledge Infrastructure (CNKI), Wanfang Database, Chinese Biomedical Literature Database, Pubmed, Embase, Cochrane, and Web of Science databases were searched by computer for publications on IMN and MIPPO in the treatment of distal tibial fractures published in official journals at home and abroad from January 2010 to August 2020. The studies included were evaluated by 2 authors using the Cochrane collaboration’s tool for assessing risk of bias. The main extraction indexes were operation time, union time, superficial infection, deep infection, malunion, delayed union or nonunion, and soft tissue irritation. Review Manager 5.3 software was used for data analysis.Results:A total of 7 studies with 653 patients were included, with 325 in the IMN group and 328 in the MIPPO group. Meta analysis showed the following: operation time in the IMN group was significantly shorter than that in the MIPPO group ( MD=-10.75, 95% CI:-19.92~-1.58, P=0.02); superficial infection rate in the IMN group was significantly lower than that in the MIPPO group ( RR=0.58, 95% CI: 0.39~0.88, P=0.01); fracture malunion rate in the IMN group was significantly higher than that in the MIPPO group ( RR=1.87, 95% CI: 1.15~3.04, P=0.01). Concerning soft tissue irritation, incidence of anterior knee pain in the IMN group was significantly higher than that in the MIPPO group ( RR=16.98, 95% CI: 3.30~87.34, P=0.0007) while incidence of soft tissue irritation at the fracture site in the IMN group was significantly lower than that in the MIPPO group ( RR=0.13, 95% CI: 0.04~0.40, P=0.0004). There were no significant differences between the 2 groups in fracture healing time, deep infection rate, delayed union rate or nonunion rate ( P>0.05). Conclusions:Although both IMN and MIPPO are fine treatments of distal tibial fractures, IMN may be superior in prevention of superficial tissue infection but prone to anterior knee pain while MIPPO may be superior in prevention of malunion but prone to soft tissue irritation at the fracture site. Therefore, MIPPO is suggested in cases with fine pretibial soft tissues while IMN is used to reduce soft tissue infection otherwise.

ABSTRACT

Objective:To investigate the clinical effect of long-stem hemiarthroplasty in the treatment of unstable intertrochanteric fracture in elderly patients with severe osteoporosis.Methods:A retrospective analysis was performed on 48 elderly patients with unstable intertrochanteric fractures of the femur with severe osteoporosis in Liaocheng People′s Hospital from April 2017 to April 2019.Twenty three patients received long-stem hemiarthroplasty (LHA group). Twenty five patients were treated with proximal femoral nail anti-rotation (PFNA) (PFNA group). PFNA group was used as the control group.The operative time, intraoperative blood loss, perioperative blood transfusion volume, number of intraoperative fluoroscopy, weight-bearing time after operation, the incidence of postoperative complications, hospitalization time, and Harris hip score of 1, 3, 6, 12 months after surgery, to investigate the efficacy of the application of long-stem hemiarthroplasty.Results:In LHA group, 23 patients were followed up for (18.6±3.9) (range from 12.0 to 26.0) months, and 25 patients in the PFNA group were followed up for (17.8±3.3)(range from 12.0 to 24.0) months.There was no significant difference in follow-up time between the two groups ( Z=-0.552, P=0.581). The operation time of LHA Group (60 (55, 73) h) was longer than that of PFNA Group (55 (50, 60) h). The intraoperative blood loss in LHA Group ((179.35±63.47) mL) was more than that in PFNA Group ((122.80±49.03) mL). The number of fluoroscopy in LHA Group (2 (2, 2) times)was less than that in PFNA Group (16 (14.5, 19.5) times). The time of weight bearing in LHA Group (4 (3, 5) d) was earlier than that in PFNA Group (33 (30, 36) d), and the differences were statistically significant ( Z=2.459, t=3.470, Z=6.216, Z=5.959; all P<0.05). There were no significant differences in perioperative blood transfusion, hospital stay and postoperative complications between the two groups (all P>0.05). Harris hip function score was significantly higher in LHA Group ((76.70±5.96), (82.13±6.38), (85.96±7.16), (88.78±7.67) points) and PFNA Group ((63.80±3.46), (71.56±2.55), (81.60±3.38), (88.08±4.83) points) increased gradually with the increase of follow-up time ( Fintra-group=432.557, Pintra-group<0.001), and the score reached the highest 12 months after operation.Harris hip function score of LHA group was higher than that of PFNA group( Finter-group=25.437, Pinter-group<0.001). There was interaction effect between follow-up time point and operation mode( Finteraction=53.464, Pinteraction<0.001). Conclusion:For the elderly patients with unstable intertrochanteric fracture with severe osteoporosis, the application of lengthened stem hemiarthroplasty can get out of bed early, reduce the complications of bed rest, reduce the number of intraoperative fluoroscopy, and recover the function of hip joint earlier and better with satisfactory results.

ABSTRACT

OBJECTIVE: The most commonly used intramedullary fixation systems for the treatment of elderly intertrochanteric fractures include the proximal femoral anti-rotation intramedullary nail (PFNA), the proximal femoral anti-rotation intramedullary nail of Asian (PFNA-II) and interlocking intramedullary nail for proximal femur (Inter-TAN), but the clinical effect of the three in the treatment of A2 and A3 type intertrochanteric fractures is still controversial. Meta-analysis was used to compare the clinical efficacy of Inter-TAN, PFNA, and PFNA-II in the treatment of unstable intertrochanteric fractures in the elderly. METHODS: A computer was used to search databases such as Cochrane, Embase, PubMed, Sinomed, CNKI, Wanfang, and VIP to collect and compare the literatures of Inter-TAN, PFNA, and PFNA-II in the treatment of elderly unstable intertrochanteric fractures. The search period was from the establishment of the database to December 2019. Two reviewers independently read the screening literature, extracted data and evaluated the quality. Meta-analysis was performed using RevMan5.3 software. RESULTS: (1) A total of eight studies were included, with 1 349 patients, including two randomized controlled studies and six cohort studies. The evidence level was ≥ III. (2) Meta-analysis showed that the operation time and intraoperative fluoroscopy time were longer, and intraoperative blood loss was more in the Inter-TAN group than those of the PFNA-II group [MD=-16.60, 95%CI (-23.22,-9.99), P 0.05). There was no significant difference in tip-apex distance, length of hospital stay, and Harris score of Inter-TAN group compared with PFNA group and PFNA-II group (P > 0.05). The incidence of postoperative screw cut-out in the Inter-TAN group was less than in the PFNA group and the PFNA-II group [OR=6.47, 95%CI(2.79, 15.00), P 0.05). CONCLUSION: For patients with osteoporosis and poor stability, Inter-TAN can provide better stability and reduce postoperative complications. For patients with poor general conditions and greater surgical risk, PFNA-II internal fixation can be selected.

ABSTRACT

BACKGROUND: Tubular bone fractures of limbs are common in traumatic orthopedics, among which anatomic intramedullary nailing has been gradually applied in clinical treatment in recent years, and has achieved good curative effect. OBJECTIVE: To summarize the application characteristics, advantages and development direction of anatomic intramedullary nailing in tubular bone fractures of limbs. METHODS: PubMed, Web of science, CNKI, Wanfang and VIP were searched for articles published from January 1900 to May 2020. The key words were “tubular bone, anatomic intramedullary nail, ulna, radius, humerus, femur, tibia, fibula” in Chinese and English. Totally 379 articles were initially examined, and 34 were finally included for review and analysis according to inclusion and exclusion criteria. RESULTS AND CONCLUSION: (1) The development history and application characteristics of anatomic intramedullary nailing in tubular bone of limbs were introduced in this paper, which was considered to have a broad clinical prospect. (2) Intramedullary nailing is gradually replacing external fixation in the treatment of tubular bone fracture, and anatomical intramedullary nailing will become the first choice of treatment. (3) Anatomic intramedullary nailing provides a better choice for intramedullary fixation of tubular bones of limbs and reduces the occurrence of related complications because its main nailing structure is more in line with the unique design of tubular bone marrow cavity of human body and the combination of distal and proximal screws with the main nailing to provide stronger holding force and anti-rotation ability. (4) The anatomic intramedullary nails have been applied in foreign countries and later in China. For example, the ZNN anatomic intramedullary nails produced by Zimmer Company in the United States are mostly used in the treatment of lower limb tubular bone fractures. In China, the anatomic intramedullary nails have just been introduced into the treatment of hip fractures (intertrochanteric and subtrochanteric fractures) and are rarely used in the treatment of tibial shaft fractures. (5) In the future, the new generation of anatomic intramedullary nails will combine biological detection, information sensing and other technologies more efficiently, so as to realize the technology and intelligence of materials.

ABSTRACT

@#A bent intramedullary (IM) nail becomes challenging and technically demanding to the orthopaedic surgeon for nail extraction. A broken nail can be easily removed through the fracture site. However, a bent nail has to be broken before it can be removed. Several studies and case reports outline the strategies and techniques for removing a bent IM nail. However, there is a paucity of guidelines and standard protocol describing the best and inexpensive strategy. We report a case where two years following surgery for intramedullary nailing of the right femur, the IM mail was bent following secondary trauma. We used a technique based on the principles of an ability to fully cut the nail and extract it in two pieces by using a Jumbo cutter which is available in the orthopaedic armamentarium. This technique is simple yet economical, with the likelihood of causing less soft tissue damage and thermal necrosis.

ABSTRACT

@#Introduction: Both short and long PFNA are employed to treat intertrochanteric fractures. Controversy exists in the choice between the two nails as each implant has specific characteristics and theoretical advantages. This retrospective study seeks to examine the operative complication rates and clinical outcomes of short versus long (Proximal Femoral Nail Antirotation) PFNA in the treatment of intertrochanteric fractures. Materials and methods: Between July 2011 and February 2015, 155 patients underwent PFNA insertion. The decision on whether to use a short or long PFNA nail, locked or unlocked, was determined by the attending operating surgeon. Visual Analogue Pain Score (VAS) Harris Hip Scores (HHS), Short-form 36 Health Questionnaire (SF-36) and Parker Mobility Scores (PMS) were collected at six weeks, six months and one year post-operatively. Results: A total of 137 (88.4%) patients were successfully followed-up. Forty-two (30.7%) patients received a short PFNA. The patients were similar in baseline characteristics of age, gender, and comorbidities. Operative time was significantly longer in the short PFNA group (62 ±17 mins) versus the long PFNA group (56±17). While the patients in both groups achieved improvement in all outcome measures, there was no significant difference between the groups in terms of HHS (61.0 ±16.0 vs 63.0 ±16.8, p=0.443), PMS (2.3±1.5 vs 2.7±2.1, p=0.545) and VAS (1.7±2.9 vs 1.8 ±2.2 p=0.454). There were 3 (7.1%) and 7 (7.4%) complications in the short versus long PFNA group, respectively. Conclusion: Both short and long PFNA had similar clinical outcomes and complication rates in the treatment of intertrochanteric fractures in an Asian population.

ABSTRACT

OBJETIVOS: Mostrar resultados, complicaciones y lecciones aprendidas utilizando el clavo intramedular magnético (IML, Intramedullary Magnetic Lengthener) en un grupo de pacientes sometidos a alargamiento óseo. PACIENTES Y MÉTODOS: Entre enero 2017 y diciembre 2019, 9 pacientes (15 segmentos), edad entre 15 y 39 años, fueron sometidos a alargamiento óseo con IML: 5 pacientes tuvieron alargamiento femoral bilateral por talla baja, 1 paciente se sometió a alargamiento de Piernas bilateral por Tibia vara y acortamiento mesomélico y 3 recibieron alargamientos femorales unilaterales por discrepancia de longitud de extremidades. Todos fueron operados por el mismo cirujano, con técnica standard. Se indicó kinesiterapia al menos 5 veces por semana durante la fase de distracción. RESULTADOS: En todos se logró el objetivo de alargamiento planteado. No hubo complicaciones intra ni postoperatorias graves (TVP, TEP, Embolia grasa), ni fallas del sistema distractor. Un paciente desarrolló contracturas articulares de ambas rodillas por no adhesión a Kinesiterapia. Ninguno requirió aporte de injerto óseo, sin embargo en 2 pacientes de alargamiento de Fémur bilateral, se presentó deformidad en varo, que hizo necesario recambio a clavo convencional y un paciente desarrolló una parálisis transitoria del Nervio Peroneo común. CONCLUSIONES: El advenimiento de los IML significó un gran avance en el campo de la osteogénesis por distracción, sin embargo, aún se trata de un procedimiento complejo, que debe ser planificado cuidadosamente para minimizar los riesgos y complicaciones. Una selección meticulosa del paciente y la evaluación física y psicológica previa, son fundamentales para el éxito del procedimiento. Los casos bilaterales requieren de un seguimiento cercano, por el riesgo de falla del implante.


objective: We show our results, complications and lessons learned using the Intramedullary Magnetic Lengthener (IML) in a group of patients who were subjected to bone lengthening. PATIENTS AND METHODS: Between January 2017 and December 2019, 9 patients (15 segments), aged between 15 and 39 years, underwent bone lengthening with IML: 5 patients had bilateral femoral lengthening due to short stature, 1 patient had bilateral leg lengthening due to Tibia vara and mesomelic shortening and 3 had unilateral femoral lengthening for limb length discrepancy. All were operated by the same surgeon, with standard technique. Physical therapy was indicated at least 5 times per week during the distraction phase. RESULTS: In every case, the proposed lengthening amount was achieved. There were no serious intraoperative or postoperative complications (DVT, Pulmonary Embolism, Fat Embolism), nor failures of the distractor system. One patient developed knee joint contracture due to non-adherence to Physical therapy. None required bone grafting, however, in 2 patients with bilateral Femur, a varus deformity appeared, which required nail exchange with a conventional trauma nail. One case developed a transit common Peroneal Nerve palsy. CONCLUSIONS: IMLs represent a great advance in the bone lengthening realm, however, it is still a complex procedure, which must be carefully planned to minimize risks and complications. Meticulous patient selection and prior physical and psychological evaluation are essential to the success of the procedure. Bilateral cases need a closer follow up, because implant failure is a potential risk.
