Fracture in Humeroradial Synostosis: Description of Two Clinical Cases.

Synostosis is a generic term to indicate the union of two originally separated bones. At the elbow, humeroradial or longitudinal synostosis causes significant disability, which varies depending on hand function, elbow positioning, adjacent joints mobility and contralateral limb function. It is estimated that, to date, a little more than 150 patients have been described with this deformity, which is more common in subjects with deficient ulnar formation or affected by conditions such as Antley-Bixler and Hermann syndromes. The lack of the elbow joint, with the formation of a longer bone due to humerus-radius fusion, results in stiffness. As such, it is assumed that fractures in this topography are not uncommon. However, since synostosis is rare, this lesion was only described twice in the literature. We report two patients with a fracture of the single bone formed by a humeroradial synostosis and Bayne type-IV ulnar formation failure. Both patients were treated surgically with success. We emphasize the need for adequate treatment to not compromise the daily activities of patients who are adapted to their deformity, thus avoiding worsening the function of a previously affected limb.

Intramedullary Fixation with Cannulated Screw After Resection of Enchondroma in the Hand: Technique Description and Case Series.

Purpose: Enchondromas are primary, benign bone neoplasms that arise from intramedullary proliferation of hyaline cartilage cells. Slow and progressive in growth, enchondromas can lead to bone destruction, deformities, and fractures. The treatment of enchondromas remains controversial. We hereby describe the technique for bone fixation using headless intramedullary screws (HISs) after enchondroma resection in the long bones of the hand. Methods: From January 2018 to June 2021, all patients treated with HISs after the resection of enchondroma of the hand were retrospectively assessed and included in the study. The series comprised four patients with a minimum postoperative follow-up period of 12 months. Postoperative functional results were measured according to Takigawa criteria and postoperative radiographic results were graded according to the Tordai system. Results: After tumor resection and screw fixation, one patient had autologous bone grafting from the iliac crest, and another had the defect filled with calcium phosphate cement. All patients were followed up for at least 12 months, and the mean healing time of the pathologic fracture was 5 weeks. There were neither complications related to the procedure nor the need for a second surgery. Conclusions: We describe the technique of intramedullary headless screws for bone fixation after enchondroma resection in the long bones of the hand, as well as the excellent functional, cosmetic, and radiographic results of four patients treated with the technique presented herewith. Type of study/level of evidence: Therapeutic IV.

Resumo Sinostose é um termo genérico utilizado para indicar a união de dois ossos originalmente separados. No cotovelo, a sinostose rádio-umeral ou longitudinal causa importante incapacidade, que varia a depender da função da mão, da posição do cotovelo, da mobilidade das articulações adjacentes e da função do membro contralateral. Estima-se que um pouco mais de 150 pacientes foram descritos até hoje com essa deformidade, sendo mais frequente em portadores de deficiência de formação ulnar ou podendo fazer parte de síndromes como de Antley-Bixler e de Hermann. Devidoàrigidezcausadapelaausênciadaarticulaçãodocotovelo,queresultana formação de um osso mais longo com a fusão do úmero no rádio, presume-se que fratura nessa topografia não seja incomum. No entanto, pela raridade dessa patologia, tal lesão apresenta apenas duas descrições prévias na literatura. Relatamos os casos de dois pacientes com fratura do osso único formado pela sinostose entre o úmero e o rádio portadores de falha de formação ulnar do tipo IV de Bayne. Ambos os pacientes foram tratados de forma cirúrgica e evoluíram bem. Salientamos a necessidade do tratamento adequado para não comprometer as atividades da vida de um paciente já adaptado à deformidade, evitando piorar a função de um membro já alterado.

Intramedullary fixation of refractory metacarpal stress fracture in a professional boxer.

Metacarpal stress fractures, although rare in the general population, are not uncommon in high performance athletes and may be seen in individuals with chronic pain associated with sports activity and with no history of acute trauma. Stress fracture fixation in skeletal long bones with different methods and implants have been discussed in the literature, both for patients who had conservative treatment failure and prophylactically. We describe the use of intramedullary cannulated screw fixation for the treatment of a 26-year-old professional boxer who complained of hand pain and swelling with 18 months evolution. After 30 days of post-operative evolution, the patient had no pain on palpation of the metacarpal base and, after three months, he was back to boxing. This is a level V evidence study. Written informed consent was obtained from the patient for publication of this case report and accompanying images.

The Flexor Carpi Radialis Portal for Arthroscopy-Assisted Reduction of the Dorsal Ulnar Fragment in Distal Radius Fractures.

Background The importance of the dorsal ulnar fragment (DUF) for stability and articular congruence of the radius is widely recognized, and standard surgical techniques often fail to ensure its reduction. Description of Technique We describe a modification of volar wrist portals for arthroscopic management of the DUF of the distal radius. It is made in an outside-in fashion in line with the flexor carpi radialis (FCR) approach for the distal radius. Through this volar portal, we achieve wide and direct visualization of the DUF, with the advantage of protecting important anatomic structures such as the FCR tendon, the radial artery, and the median nerve; all protected with the previously made volar approach for the distal radius. In addition, easy manipulation and reduction of the DUF is obtained with instrumentation through standard dorsal portals. Patients and Methods We performed this procedure in 23 patients with distal radius fractures (DRF) with displaced DUF. Results Early and late postoperative evaluation demonstrated intraoperative reduction maintenance and adequate range of motion, compatible with the usual findings of standard volar plating, with the benefit of anatomic reduction of the DUF. Conclusion With our technique, volar plating associated with arthroscopy-assisted dorsal fragment specific fixation with dorsal standard and the FCR portals permits optimal surgical treatment of most DRFs.

Bilobed Flap in Hand Clinodactyly Reconstruction: Technique Description and Result Appraisal.

Objective Clinodactyly is a congenital hand deformity that is characterized by coronal angular deviation and may occur in thumbs or fingers. Surgical treatment is indicated for severe angulations. Among the described techniques, one of the options consists of bone alignment by wedge-shaped addition osteotomy of the anomalous phalanx. Such alignment maneuver creates a problem in skin cover, along with soft-tissue tension at the concave aspect of the deformity. Hence, some sort of skin flap is required for the adequate operative wound closure. We aim to demonstrate the aforementioned technique and to assess the results of bilobed flap in the treatment of hand clinodactyly. Methods Retrospective study conducted between January 2008 and January 2015. Five patients were included in the study, including nine operated digits. Surgical indication consisted of angular deviations ˃ 30 o . Neither patients with thumb deformities nor those with deformities associated to syndromes were excluded from the study. We assessed the functional and cosmetic outcomes of the technique, as well as complications and the satisfaction rates of the family. Results All patients had satisfactory functional and cosmetic results, with a mean skin healing of 18.6 days. Among nine operated digits, only one of the patients presented vascular compromise at the distal portion of the first flap lobe, albeit without necrosis or the need for any additional procedure. Patients were followed up on a minimum of 12-month interval. No deformity recurred during the observation period. Conclusion Bilobed flap for the treatment of hand clinodactyly is a good option for skin cover after the osteotomy.

Resumo Objetivo A clinodactilia é uma deformidade congênita da mão, caracterizada por desvio angular coronal, podendo ocorrer em polegares ou dedos. O tratamento cirúrgico é indicado para angulações severas. Dentre as técnicas descritas, uma das opções consiste no alinhamento ósseo, através de osteotomia em cunha de adição da falange anômala. Essa manobra de alinhamento gera uma dificuldade de cobertura cutânea, juntamente com a tensão das partes moles no lado côncavo da deformidade. Sendo assim, algum tipo de retalho cutâneo é necessário para o fechamento adequado da ferida cirúrgica. Objetivamos demonstrar a técnica citada e avaliar os resultados do retalho bilobado no tratamento das clinodactilias da mão. Métodos Estudo retrospectivo entre janeiro de 2008 e janeiro de 2015. Foram incluídos cinco pacientes no estudo, nove dedos foram submetidos à cirurgia. Tiveram indicação cirúrgica os pacientes com desvios angulares nos dedos acima de 30 graus. Não foram excluídos do estudo os pacientes com deformidades no polegar, nem aqueles com deformidades associadas a síndromes. Foram avaliados os resultados funcionais e estéticos com o uso desta técnica, assim como as complicações e o grau de satisfação dos familiares. Resultados Todos os pacientes apresentaram resultados funcionais e estéticos satisfatórios, com cicatrização cutânea média de 18,6 dias. Entre os nove dedos submetidos à cirurgia, apenas um dos pacientes apresentou comprometimento vascular na porção distal do primeiro lobo do retalho, porém sem necrose ou necessidade de qualquer procedimento adicional. Os pacientes foram acompanhados durante um intervalo mínimo de 12 meses. Nenhuma deformidade ocorreu durante o período de observação. Conclusão O uso do retalho bilobado no tratamento das clinodactilias da mão é uma boa opção para cobertura cutânea após a realização de osteotomia.

Volar Wrist Ganglion Originating at the Dorsal Scapholunate Ligament - A Report of Two Patients.

Ganglion cysts are common wrist lesions and, in about 20% of patients, they appear on a volar and radial location. Volar ganglions typically arise from the volar radiocarpal joint in the interval between the radioscaphocapitate (RSC) and the long radiolunate (LRL) ligaments. We report two patients with volar and radial ganglion cysts that originated at the dorsum of the scapholunate (SL) ligament. This may lead to inadequate treatment with a risk of recurrence. Level of Evidence: Level V (Therapeutic).

Intramedullary Fixation with Headless Screws versus Bouquet in Unstable Metacarpal Neck Fractures in Active Patients: A Randomized Study.

Objeticve To compare the range of motion (ROM), return-to-work time, visual analogue score (VAS), disability of the arm, shoulder, and hand (QuickDASH), and radiographic outcomes of two methods of definitive internal fixation in active patients with boxer's fractures, operated in the first week. Methods This was a prospective, randomized trial, in which 50 patients, with a mean age range of 18 to 40 years old, were randomized and treated to definitive intramedullary fixation using 2 headless screws ( n = 20) or bouquet (2 or 3 Kirschner wires) ( n = 20). The patients were assessed on return-to-work time, ROM, patient reported QuickDASH outcome, VAS, and radiographic evaluation at 6 months. Results At 6 months, there were no differences between the two groups in terms of ROM, postoperative pain (VAS), or QuickDASH score. The overall complication rate was 4.76% in the screw group, compared with 5% in the bouquet-fixation group. Conclusions In the treatment of the active patients with unstable boxer's fractures, headless screws and bouquet fixation proved to be a safe and reliable treatment. The outcomes were similar in both groups.

The outcomes were similar in both groups.

Resumo Objetivo Comparar a amplitude de movimento (ADM), o tempo de retorno de trabalho, a pontuação na escala visual analógica (EVA), o escore no questionário abreviado incapacidade do braço, ombro e mão (QuickDASH, na sigla em inglês) e os resultados radiográficos de dois métodos de fixação interna definitiva em pacientes ativos com fraturas do boxer; operados na primeira semana. Métodos Este foi um ensaio prospectivo randomizado, no qual 50 pacientes, com idade mediana na faixa de 18 a 40 anos, foram randomizados e tratados com fixação intramedular definitiva utilizando 2 parafusos de compressão (n = 20) ou buquê (2 ou 3 fios de Kirschner) (n = 20). Os pacientes foram avaliados em relação ao tempo de retorno ao trabalho, à ADM, ao desfecho relatado pelo paciente no questionário QuickDASH, à EVA e à avaliação radiográfica aos 6 meses. Resultados Aos 6 meses, não houve diferenças entre os 2 grupos em termos de ADM, dor pós-operatória (EVA) ou escore no QuickDASH. A taxa global de complicações foi de 4,76% no grupo de fixação com parafusos, em comparação com 5% no grupo de fixação com a técnica do buquê. Conclusões Parafusos de compressão e fixação com buquês provaram ser tratamentos seguros e confiáveis para pacientes ativos com fraturas instáveis. Os resultados foram semelhantes nos dois grupos.

Bridging versus Nonbridging Dynamic External Fixation of Unstable Distal Radius Fractures in the Elderly with Polytrauma: A Randomized Study.

Background Despite the high prevalence of unstable distal radius fractures (DRFs), there is no consensus regarding the optimal method and treatment timing, especially for elderly patients with multiple associated injuries. Purpose This study aimed to compare the grip strength achieved with two different methods for definitive dynamic external fixation of DRFs in elderly patients with polytrauma operated on within the first 24 hours. Methods In this prospective randomized trial, 35 patients were assigned to undergo definitive external dynamic fixation of DRFs using the nonbridging (group A) or bridging (group B) method. The grip strength, range of motion (ROM), Disabilities of the Arm, Shoulder and Hand (QuickDASH) outcome measure, visual analog scale (VAS) score for pain, and radiographic characteristics were evaluated at 6 and 12 months. Results At 12 months, no significant between-group difference was observed with respect to grip strength. All patients showed results in the third or fourth quartiles. The mean ROMs were 96.94 and 96.38% and the mean QuickDASH scores were 3.53 and 3.85 in groups A and B, respectively. The VAS scores were 1.60 and 1.85 in groups A and B, respectively. The overall complication rates were 13.3 and 15% in groups A and B, respectively. Initial fracture reduction was maintained in 86.67 and 95% of the patients in groups A and B, respectively. Conclusions Both bridging and nonbridging external definitive dynamic fixation proved safe and reliable for the treatment of unstable DRFs in elderly patients with polytrauma. The grip strength results in both groups predicted the restoration of ability in elderly patients to perform activities of daily living independently.

Reconstruction of Radioscaphocapitate Ligament in Treatment of Ulnar Translation.

Background This article measures the life quality, clinical, and functional outcomes of a patient who had undergone reconstruction of the radioscaphocapitate ligament (RSL), using brachioradialis tendon in the treatment of ulnar translation of the carpus. Case Description We present a 36-year-old man with ulnar translation in his left, nondominant wrist, after fall accident. Reconstruction of the RSL was performed. One year later, the patient experienced good evaluation. Wrist flexion was 70 degrees, extension was 60 degrees, radial deviation was 20 degrees, and ulnar deviation was 30 degrees. Forearm pronation was 85 degrees and supination was 90 degrees and digit motion was full. Disabilities of the Arm, Shoulder and Hand score of 5, Visual Analog Scale of 0, and grip strength of 82% were obtained compared with the unaffected side. Wrist radiographic aspects showed radiocarpal joint congruency. The period of fixator treatment was 8 weeks. Good stability and joint congruency of the radiocarpal joint were obtained. Good radiographic, clinical, and functional results were obtained improving the quality of life of the patient. Literature Review The treatment of ulnar translation is difficult and complicated. There is no consensus to the overall management. As there is still a lack of long-term results, the indications for surgery, various surgical options, and the type of intervention have been a matter of controversy in the literature. Would radiocarpal joint be stable when reconstruction of the RSL using brachioradialis tendon was obtained? Is it possible to reduce an ulnar translation with this technique? Clinical Relevance We would like to suggest that the radiocarpal ligament reconstruction will improve the outcome. We believe that this technique will make the wrist more stable and functional. We agree that the best time to perform the corrections is early. The authors prefer to first reconstruct the RSL and then the radiocarpal ligament suture or radioscapholunate arthrodesis.

Ligamentous reconstruction of the interosseous membrane of the forearm in the treatment of instability of the distal radioulnar joint.

OBJECTIVES: To measure the quality of life and clinical outcomes of patients treated with interosseous membrane (IOM) ligament reconstruction of the forearm, using the brachioradialis (BR), and describe a new surgical technique for the treatment of joint instability of the distal radioulnar joint (DRUJ). METHODS: From January 2013 to September 2016, 24 patients with longitudinal injury of the distal radioulnar joint DRUJ were submitted to surgical treatment with a reconstruction procedure of the distal portion of the interosseous membrane or distal oblique band (DOB). The clinical-functional and radiographic parameters were analyzed and complications and time of return to work were described. RESULTS: The follow-up time was 20 months (6-36). The ROM averaged 167.92° (93.29% of the normal side). VAS was 2/10 (1-6). DASH was 5.63/100 (1-18). The time to return to work was 7.37 months (3-12). As to complications, one patient had an unstable DRUJ, and was submitted to a new reconstruction by the Brian-Adams technique months. Currently, he has evolved with improved function, and has returned to his professional activities. Three other patients developed problems around the transverse K-wire and were treated with its removal, all of whom are doing well. CONCLUSION: The new approach presented in this study is safe and effective in the treatment of longitudinal instability of the DRUJ, since it has low rate of complications, as well as satisfactory radiographic, clinical, and functional results. It allows return to social and professional activities, and increases the quality of life of these patients.

Ulnar Lengthening/Reconstruction of Interosseous Membrane in Treatment of Osteochondroma.

BACKGROUND: We aim to measure the quality of life and clinical and functional outcomes of a patient who had undergone ligament reconstruction of the forearm interosseous membrane, using brachioradialis tendon more ulna distraction osteogenesis in treatment with multiple cartilaginous exostosis. CASE DESCRIPTION: We present a 11-year-old boy with congenital deformity in his right, dominant forearm,Type IIb by Masada classification. Distraction of the ulna, resection of exostosis, and reconstruction of the distal part of the interosseous membrane was performed. One year later, the patient experienced good evaluation. Wrist flexion was 70 degrees, extension was 60 degrees, radial deviation was 20 degrees, and ulnar deviation was 30 degrees. Forearm pronation was 60 degrees and supination was 90 degrees. Elbow flexion was 120 degrees, extension was -5 degrees, and digit motion was full. DASH score of 5, VAS of 0, and grip strength of 92% compared to the unaffected side were obtained. Forearm radiographic aspects showed healing of the distraction, articular congruency, the distal radioulnar joint (DRUJ), and radiocapitellum joint. The distraction distance was 28 mm, the distraction period was 67 days, the consolidation period was 96 days, and the period of fixator treatment was 92 days. The distraction speed was 0.5 mm/day. Good stability and joint congruency of the DRUJ and elbow were obtained. Good radiographic, clinical, and functional results were obtained improving the life quality of that patient. LITERATURE REVIEW: The treatment of forearm deformities is difficult and complicated. There is no consensus to the overall management. As there is still a lack of long-term results, the indications for surgery, various surgical options, and the timing of the intervention have been a matter of controversy in the literature. Would DRUJ be stable when ulnar lengthening is combined with excision of exostosis? Is it possible to reduce the radial head with this technique? CLINICAL RELEVANCE: We would like to suggest an interosseous membrane (distal oblique band) reconstruction to improve this treatment. We believe this suggestion could maintain DRUJ and elbow more stable and functional. We agree that the best time to perform the corrections is early and gradually. We prefer to correct the ulna, radius, DRUJ and elbow in many steps than in only one procedure.

Dorsal capsulodesis associated with arthoscopy-assisted scapholunate ligament reconstruction using a palmaris longus tendon graft.

OBJECTIVES: To measure the quality of life, the time to work return, and clinical, functional, and radiographic parameters of patients treated with dorsal capsulodesis associated with scapholunate (SL) reconstruction, assisted by arthroscopy. METHODS: From January 2015 to September 2016, 14 adult patients with SL dissociation underwent surgical treatment with the SL reconstruction procedure assisted by arthroscopy, using the new technique proposed in this study. All patients were assessed by the occupational therapy department at regular intervals after surgery and performed the same sequence of rehabilitation. The parameters analyzed were: range of motion (ROM), Disability of the Arm, Shoulder, and Hand (DASH), visual analog scale (VAS), and radiographic analysis to visualize the pre- and postoperative SL gap and the pre- and postoperative dorsal intercalated segment instability (DISI) deformity the. The complications and the time to return to work activities were described. RESULTS: The follow-up time was 12 months (3-17). The ROM averaged 321° (96.9% of the normal side). VAS was 1.79/10 (1-6). DASH was 6.50/100 (1-30). The time to work return work was 4.42 months (2-17). As for complications, one patient developed SLAC, and underwent four-corner fusion one year after ligament reconstruction. Currently, he has experienced pain relief, with a functional range of motion of the wrist, and has not yet returned to professional activities.The preoperative SL gap was 4.29 mm (2-7); in the postoperative period, it was 1.79 mm (1-4). The DISI deformity was present in ten patients with SL angle > 70° (preoperative) and it was corrected after surgery, in all patients. SLAC stage I was identified in a patient. Arthroscopy was performed in all cases. The SL instability was classified as Geissler grade III in four cases and as grade IV in ten cases. CONCLUSION: The new approach (dorsal capsulodesis associated with SL reconstruction, assisted by arthroscopy) presented in this study is safe and effective in the treatment of SL dissociation, since it offers satisfactory clinical, radiographic and functional results, showing low rates of complications. For patients, it allows the return to their social and professional activities, and increases their life quality.

MÉTODOS: De janeiro de 2015 a setembro de 2016, 14 pacientes, esqueleticamente maduros, adultos, com dissociação escafolunar (SL), foram submetidos ao tratamento cirúrgico com o procedimento de reconstrução do ligamento escafossemilunar assistido por artroscopia com a nova técnica proposta neste estudo. Todos os pacientes foram avaliados pelo setor de terapia ocupacional em intervalos regulares de pós-operatório e fizeram a mesma sequência de reabilitação. Os parâmetros analisados foram: arco de movimento (ADM), Disability Arm, Shoulder and Hand (Dash), escala visual analógica (EVA) e análise radiográfica pré e pós-operatória para visualizar o espaço escafolunar (sinal de Terry-Thomas) e deformidade em Dorsal Intercalated Segment Instability (DISI) pré e pós-operatória. Descrição das complicações e o tempo de retorno ao trabalho. RESULTADOS: O tempo de seguimento foi de 12 meses [3-17]. O ADM foi em média 321,07° (96,9% do lado normal). O valor da avaliação subjetiva da dor (VAS) foi 1,79/10 [1-6]. A mensuração da qualidade de vida pelo Dash foi de 6,50/100 [1-30]. O tempo de retorno ao trabalho foi de 4,42 meses [2-17]. Quanto às complicações, uma paciente evoluiu com SLAC e foi submetida à artrodese dos quatro cantos um ano após a reconstrução ligamentar. Evoluiu com melhoria da dor e está com o ADM do punho funcional, mas ainda não retornou às atividades profissionais. O intervalo do SL (gap) pré-operatório foi de 4,29 mm [2-7] e o pós-operatório foi de 1,79 mm [1-4]. A deformidade DISI estava presente em dez pacientes, com um ângulo SL acima de 70° (pré-operatório), e foi corrigida após a cirurgia em todos os pacientes. SLAC estágio I foi identificado em um paciente. A artroscopia foi feita em todos os casos. A instabilidade SL foi classificada como um grau Geissler III em quatro casos e grau IV em dez casos. CONCLUSÃO: A nova abordagem (capsulodese dorsal associada à reconstrução ligamentar escafossemilunar assistida por artroscopia) apresentada neste estudo é segura e eficaz no tratamento da dissociação escafolunar, já que apresenta resultados radiográficos, clínicos e funcionais satisfatórios, demonstra baixas taxas de complicações, permite o retorno às atividades sociais e profissionais e aumenta a qualidade de vida desses pacientes.

Dorsal capsulodesis associated with arthoscopy-assisted scapholunate ligament reconstruction using a palmaris longus tendon graft / Capsulodese dorsal associada à reconstrução assistida por artroscopia do ligamento escafossemilunar com enxerto do tendão do músculo palmar longo

ABSTRACT OBJECTIVES: To measure the quality of life, the time to work return, and clinical, functional, and radiographic parameters of patients treated with dorsal capsulodesis associated with scapholunate (SL) reconstruction, assisted by arthroscopy. METHODS: From January 2015 to September 2016, 14 adult patients with SL dissociation underwent surgical treatment with the SL reconstruction procedure assisted by arthroscopy, using the new technique proposed in this study. All patients were assessed by the occupational therapy department at regular intervals after surgery and performed the same sequence of rehabilitation. The parameters analyzed were: range of motion (ROM), Disability of the Arm, Shoulder, and Hand (DASH), visual analog scale (VAS), and radiographic analysis to visualize the pre- and postoperative SL gap and the pre- and postoperative dorsal intercalated segment instability (DISI) deformity the. The complications and the time to return to work activities were described. RESULTS: The follow-up time was 12 months (3-17). The ROM averaged 321° (96.9% of the normal side). VAS was 1.79/10 (1-6). DASH was 6.50/100 (1-30). The time to work return work was 4.42 months (2-17). As for complications, one patient developed SLAC, and underwent four-corner fusion one year after ligament reconstruction. Currently, he has experienced pain relief, with a functional range of motion of the wrist, and has not yet returned to professional activities. The preoperative SL gap was 4.29 mm (2-7); in the postoperative period, it was 1.79 mm (1-4). The DISI deformity was present in ten patients with SL angle > 70° (preoperative) and it was corrected after surgery, in all patients. SLAC stage I was identified in a patient. Arthroscopy was performed in all cases. The SL instability was classified as Geissler grade III in four cases and as grade IV in ten cases. CONCLUSION: The new approach (dorsal capsulodesis associated with SL reconstruction, assisted by arthroscopy) presented in this study is safe and effective in the treatment of SL dissociation, since it offers satisfactory clinical, radiographic and functional results, showing low rates of complications. For patients, it allows the return to their social and professional activities, and increases their life quality.

RESUMO OBJETIVOS: Mensurar a qualidade de vida, o tempo de retorno ao trabalho, os resultados clínicos, funcionais e radiográficos dos pacientes submetidos à capsulodese dorsal associada à reconstrução ligamentar escafossemilunar assistida por artroscopia. MÉTODOS: De janeiro de 2015 a setembro de 2016, 14 pacientes, esqueleticamente maduros, adultos, com dissociação escafolunar (SL), foram submetidos ao tratamento cirúrgico com o procedimento de reconstrução do ligamento escafossemilunar assistido por artroscopia com a nova técnica proposta neste estudo. Todos os pacientes foram avaliados pelo setor de terapia ocupacional em intervalos regulares de pós-operatório e fizeram a mesma sequência de reabilitação. Os parâmetros analisados foram: arco de movimento (ADM), Disability Arm, Shoulder and Hand (Dash), escala visual analógica (EVA) e análise radiográfica pré e pós-operatória para visualizar o espaço escafolunar (sinal de Terry-Thomas) e deformidade em Dorsal Intercalated Segment Instability (DISI) pré e pós-operatória. Descrição das complicações e o tempo de retorno ao trabalho. RESULTADOS: O tempo de seguimento foi de 12 meses [3-17]. O ADM foi em média 321,07° (96,9% do lado normal). O valor da avaliação subjetiva da dor (VAS) foi 1,79/10 [1-6]. A mensuração da qualidade de vida pelo Dash foi de 6,50/100 [1-30]. O tempo de retorno ao trabalho foi de 4,42 meses [2-17].

Randomized clinical trial between proximal row carpectomy and the four-corner fusion for patients with stage II SNAC.

OBJECTIVE: To compare the outcomes of patients with stage II SNAC submitted to surgical treatment by proximal row carpectomy (PRC) or four-corner fusion (FCF). METHOD: Twenty-seven patients aged 18-59 years (mean 37.52 years) were included. Thirteen patients underwent PRC in Group A, and 14 underwent FCF of the wrist in Group B. Evaluations were made before and after surgery with follow-up between 45 and 73 months. Range of motion (ROM); pain assessment with a visual analog scale (VAS); grip strength; disability of the arm, shoulder, and hand (DASH); and return to work were evaluated. RESULTS: Group A patients had 68.5% and Group B patients, 58.01% of the ROM of the contralateral side. The VAS score was 2.3 in Group A and 2.9 in Group B. Grip strength was 78.67% and 65.42%, respectively, relative to the side not affected. The DASH score was 11 for PRC and 13 for FCF. In Group A, 9/13 (69.23%) and in Group B, 8/14 (57.14%) patients are currently working. Complications were symptomatic osteoarthritis in the mid-carpal joint in Group A and loosening of a screw in Group B. CONCLUSION: The clinical and functional results do not present statistically significant differences for both analyzed methods.

OBJETIVOS: Comparar os resultados clínicos e funcionais dos pacientes com diagnóstico de Scaphoid Non Union Advanced Colapse (SNAC), no estágio II, submetidos à ressecção da fileira proximal do carpo ou à artrodese dos quatro cantos. MÉTODO: Foram incluídos no estudo 27 pacientes, com média de 37,52 anos (18-59). Treze foram submetidos à carpectomia proximal no Grupo A e 14 à artrodese dos quatro cantos no Grupo B. O seguimento médio foi de 45 a 73 meses. Foram avaliados os arcos de movimento, a dor, a força de preensão palmar, o Disability Arm Shoulder Hand (DASH) escore e o retorno ao trabalho. RESULTADOS: No Grupo A os pacientes apresentaram 68,5% do arco de movimento no lado não afetado e no Grupo B, 58,01%. Na avaliação subjetiva da dor (VAS), obtivemos 2,3 no Grupo A e 2,9 no Grupo B. A força de preensão palmar foi de 78,67% no Grupo A do lado não acometido e de 65,42% no Grupo B. O DASH escore no Grupo A foi 11 e no Grupo B, 13. Quanto ao trabalho, 69,23% (9/13) dos pacientes no Grupo A e 57,14% (8/14) no Grupo B retornaram a alguma atividade laboral. A taxa de complicações no Grupo A foi de (1/13) e no Grupo B, de 7,1% (1/14). CONCLUSÕES: Os resultados clínico-funcionais estudados não apresentam diferenças estatísticas para os dois métodos analisados.
