Total Wrist Arthrodesis: A Preoperative Test to Predict Functional Outcomes / Artrodese total do punho: Um teste pré-operatório para prever resultados funcionais

Abstract Objective The study aims to demonstrate an evaluation method to predict the functional success of total wrist arthrodesis (TWA) and assist its indication. Methods A prospective study including ten patients submitted to (TWA) posttraumatic arthritis. Exclusion criteria were patients who lost postoperative follow-up or incomplete information in the medical record. The objective functional assessment (handgrip strength, three-point pinch, lateral pinch and pulp-pulp pinch) and the subjective functional assessment (DASH, PRWE, EVA) were evaluated in 3 different periods: (1) Before surgery without articular anesthesia, (2) Before surgery under articular anesthesia and (3) 12 weeks after the surgical procedure. Results There was an increase in handgrip strength in all three pinches measurements after pain relief, both after joint anesthesia and after the consolidation of the arthrodesis (p < 0.05). In the comparisons between the subjective evaluations (DASH, PRWE and VAS), the patients had better scores in the postoperative evaluation after 12 weeks (p < 0.05). There was no statistical difference when comparing the mean strength values found after anesthesia and after 12 weeks of TWA. Conclusion the outcomes could propose an assessment protocol for patients with indication for TWA, in which patients with good response to intra-articular anesthetic infiltration would benefit from the effects of the surgical procedure.

Resumo Objetivo O estudo tem como objetivo demonstrar um método de avaliação para predizer o sucesso funcional da artrodese total do punho (ATP) e auxiliar na sua indicação. Métodos Um estudo prospectivo incluindo dez pacientes submetidos a ATP por artrite pós-traumática. Os critérios de exclusão foram pacientes que perderam o acompanhamento pós-operatório ou informações incompletas no prontuário. A avaliação funcional objetiva (força de preensão manual, pinça de três pontos, pinça lateral e pinça polpa-a-polpa) e a avaliação funcional subjetiva (DASH, PRWE, EVA) foram avaliadas em 3 momentos diferentes: (1) Antes da cirurgia sem anestesia articular, (2) Antes da cirurgia sob anestesia articular e (3) 12 semanas após o procedimento cirúrgico. Resultados Houve aumento da força de preensão palmar nas três medidas de pinça após o alívio da dor, tanto após a anestesia articular quanto após a consolidação da artrodese (p < 0,05). Nas comparações entre as avaliações subjetivas (DASH, PRWE e VAS), os pacientes tiveram melhores escores na avaliação pós-operatória após 12 semanas (p < 0,05). Não houve diferença estatística ao comparar os valores médios de força encontrados após a anestesia e após 12 semanas de ATP.

Preliminary application of a novel distraction reductor in the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution / 中华创伤骨科杂志

Objective:To evaluate a novel distraction reductor in the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution.Methods:From January 2019 to December 2020, 27 patients with unstable distal radius fracture complicated with metaphyseal volar comminution were treated at Department of Orthopaedics, Zhoupu Hospital Affiliated to Shanghai University of Medicine & Health Sciences. They were 6 males and 21 females, with an age of (69.4±9.4) years. All fractures were unilateral and closed, involving the right side in 17 cases and the left side in 10 cases. All patients were treated by internal fixation with an anatomical locking plate through the volar approach and the novel distraction reductor was used to reduce the fracture ends. Regular imaging examinations were performed to evaluate the reduction, maintenance and union of fractures after surgery. One year after operation, the curative efficacy was assessed by evaluation of the range of wrist motion, Disabilities of the Arm, Shoulder and Hand (DASH) score, Gartland-Werley score and Bartra radiology score.Results:All the operations went on successfully with a duration of (92.3±8.9) min. All the incisions healed primarily. The follow-up time was (15.9±2.9) months. The radial height, palmar tilt, ulnar inclination and articular surface step-off immediately after operation [(11.23±1.51) mm, 12.10°±3.44°, 20.54°±3.44°, and (0.95±0.42) mm] were not significantly lost compared with those one year after operation [(11.22±1.55) mm, 12.07°±3.44°, 20.51°±3.33°, and (0.93±0.40) mm] (all P>0.05). One year after operation, the range of wrist motion was good with dorsiflexion of 59.7°±5.5°, palm flexion of 63.0°±9.1°, pronation of 66.5°±5.5°, supination of 61.2°±5.6°, radial deviation of 22.7°±4.8°, and ulnar deviation of 30.3°±6.1°; DASH score was 13.5±5.5; Bartra radiology score was 88.6±6.5, giving an excellent and good rate of 88.9% (24/27);Gartland-Werley score was 2.7±2.1, giving an excellent and good rate of 92.6% (25/27). Follow-ups observed no poor fracture healing, internal fixation failure, tendon or nerve injury or traumatic arthritis. Conclusion:In the surgical treatment of unstable distal radius fractures with metaphyseal volar comminution, the novel distraction reductor can lead to ideal reduction of displaced fractures and effectively correct the shortening caused by volar cortex comminution to achieve satisfactory functional effects in clinic.

Research progress in the diagnosis and treatment of radiocarpal fracture-dislocation / 中华创伤杂志

Radiocarpal fracture-dislocation (RFD) is a rare injury normally associated with the destruction of bones, joints and ligaments. The improper diagnosis and treatment of RFD will cause severe complications and affect the long-term function of wrist joints. The difficulties of clinical diagnosis and treatment lie in the accurate diagnosis, identification and reconstruction of the structure of specific injury. As the foreign and domestic literatures are mainly case analyses or systemic case reports rather than large-scale reports, there still lacks a systemic knowledge of the standard diagnosis and treatment of RFD clinically, thus leading to problems such as missed diagnosed or misdiagnosed, improper application of treatment methods and incomplete reconstruction. Therefore, the authors reviewed relevant literatures about the features, diagnosis and treatment of RFD, in order to provide references for the clinical diagnosis and treatment of RFD.

Conclusion Awkward postures are related to wrist pain among workers in selected 10 key industries. The related factors are wrist on hard edge, frequent wrist bending, finger pinching, fixed wrist bending, and arms over shoulders.

Use of the Triquetrum-Hamate Portal in FourCorner Wrist Fusion: A Useful Technical Trick / Uso do portal piramidal-hamato na fusão de punho de quatro cantos: Um bom truque técnico

Abstract Arthroscopy-assisted partial wrist-fusion techniques are becoming more popular nowadays. It became clearer that avoiding the violation of important ligament and tendinous structures - which is impossible when using the classic open techniques - enables a more biological approach, which is essential for faster healing and improvement in function. We describe the use of the triquetrum-hamate (TH) portal, which is seldomly applied in routine arthroscopic techniques for hand and wrist surgery, as an accessory portal to better perform anterior midcarpal debridement in four-corner fusion. This trick enables an almost complete anterior resection of the capitate and hamate chondral surfaces, increasing the subchondral osseous contact in the midcarpal joint after fixation, thus leading to higher consolidation rates.

Resumo As técnicas de fusão parcial do punho assistidas por artroscopia estão se tornando mais populares. Ficou claro que evitar a violação de importantes estruturas ligamentares e tendíneas, o que é imposssível com as técnicas abertas clássicas, permite uma abordagem mais biológica, essencial para a cicatrização mais rápida e melhora da função. Descrevemos o uso do portal piramidal-hamato (PH), raramente aplicado em técnicas artroscópicas de rotina para cirurgia de mão e punho, como portal acessório para melhor execução do desbridamento carpal medial anterior na fusão de quatro cantos. Esse truque possibilita a ressecção anterior quase completa das superfícies condrais do capitato e do hamato, o que aumenta o contato ósseo subcondral na articulação mesocárpica após a fixação e eleva as taxas de consolidação.

Types of ulnar styloid process fracture and treatment of distal radius fracture / 中华创伤骨科杂志

Objective:To investigate the effects of types of ulnar styloid process fracture on the treatment of distal radius fracture.Methods:The 80 patients were analyzed retrospectively who had been treated at The First Department of Hand Surgery, Honghui Hospital from January 2019 to January 2020 for fracture of distal radius complicated with fracture of ulnar styloid process. They were 25 males and 55 females, aged from 30 to 85 years (average, 58.6 years). According to the types of ulnar styloid process fracture, 40 patients were assigned into a Hauck type Ⅰ group and the other 40 into a Hauck type Ⅱ group. The 2 groups were compared in terms of operation, postoperative complications, hospital stay, bone union, visual analogue scale (VAS) on postoperative 1 to 3 days, and modified Mayo wrist function score, wrist range of motion and quality of life by WHOQOL-BREF at the last follow-up.Results:The 2 groups were comparable because there was no significant difference in age, gender, American Society of Anesthesiologists (ASA) rating, or time from injury to operation between them ( P>0.05). All the patients were followed up for 12 to 24 months (average, 17 months). There was no significant difference between Hauck type Ⅰ group and Hauck type Ⅱ group in operation time, intraoperative blood loss, hospital stay, rate of postoperative complications, fracture union, modified Mayo wrist function score or VAS on postoperative 1 to 3 days ( P>0.05). At the last follow-up, the palm tilt and ulnar inclination angles were 13.8°±1.9° and 21.6°±2.8° in Hauck type Ⅰ group, significantly larger than those in Hauck type Ⅱ group (11.9°±1.6° and 18.8°±2.3°) ( P<0.05). At the last follow-up, Hauck Ⅰ group scored 85.3±6.4,85.6±6.5, 84.7±6.3 and 85.0±6.7 respectively in the domains of physical health, psychology, environment and social relationships, significantly higher than those Hauck type Ⅱ group did (78.5±6.5, 78.9±6.5, 77.8±6.1 and 77.9±6.3) ( P<0.05). Conclusions:In open reduction and internal fixation for distal radius fracture, Hauck Type Ⅰ fracture of ulnar styloid process has no significant effect on the functional recovery of the wrist but Hauck Type Ⅱ fracture of ulnar styloid process may. Therefore, surgical fixation needs to be strengthened if Hauck Type Ⅱ fracture of ulnar styloid process is complicated.

Comparison of diagnostic value of ultrasound and multi-slice spiral CT in wrist joint lesions of rheumatoid arthritis / 中国医师进修杂志

Objective:To investigate the diagnostic value and imaging characteristics of ultrasound and multi-slice spiral CT in rheumatoid arthritis (RA) wrist joint lesions.Methods:The clinical data of 54 cases of RA wrist arthropathy in Jianhu Hospital Affiliated to Nantong University from December 2018 to April 2020 were analyzed. All the patients were examined by ultrasound and multi-slice spiral CT. The imaging characteristics of ultrasound and multi-slice spiral CT were analyzed, and the detection rates of synovitis, joint effusion, tenosynovitis, bone erosion and wrist joint lesions were calculated.Results:A total of 1 188 joints were examined in 54 patients with RA, including 108 wrist joints, 540 metacarpophalangeal joints and 540 proximal interphalangeal joints. There was no significant difference in the detection rate of wrist joint synovitis, joint effusion and tenosynovitis between ultrasound and CT ( P>0.05). The wrist joint lesions detection rates of ultrasound and CT were 97.2%(105/108) and 46.3% (50/108), the difference was statistically significant ( χ2 = 36.52, P<0.05). Ultrasound image features: synovitis ultrasound image showed hypoechoic joint cavity, not by joint displacement or compression image, color Doppler flow imaging (CDFI) examination could see blood flow signal;joint effusion in ultrasound image of joint effusion was strip, strip-shaped, non-uniform distribution, image was affected by joint displacement or compression, CDFI examination had no blood flow signal; bone erosion ultrasound image showed bone cortical continuous interruption or "crater" "insect erosion" like defects. CT imaging features: wrist joint space narrow, osteoporosis, some patients with scaphoid, distal radius visible bone erosion. Conclusions:The detection rate of wrist synovitis, joint effusion and tenosynovitis by ultrasound and multi-row spiral CT are similar. The multi-row spiral CT examination have a slight advantage in evaluating the joint space and bone changes. The sensitivity of wrist bone erosion and wrist joint lesions are higher than those of multi-row spiral CT, which can guide the early clinical diagnosis and treatment of RA.

Objective:To investigate the clinical efficacy of robotic navigation and percutaneous internal fixation in the treatment of fresh undisplaced scaphoid lumbar fractures.Methods:From November 2019 to October 2020, 8 patients were treated at Department of Hand Surgery, Xuzhou Renci Hospital for fresh undisplaced scaphoid lumbar fractures. There were 7 males and one female with an average age of 27.5 years (from 18 to 42 years), and 5 left and 3 right cases. Navigation by a Tianji orthopedic robot was conducted to decide the positions for implantation of percutaneous Herbert screws to fixate the fractures. The bone healing was followed up by regular X-ray and CT examinations. The functional recovery was evaluated by Mayo wrist score, grip strength, pinch strength and wrist range of motion, and the wrist pain was evaluated by visual analogue scale (VAS).Results:All the 8 patients were followed up for a mean time of 12.8 months (from 6 to 19 months). All the wounds healed by the first intention without any inflammation or infection. CT examination at 3 months postoperation found that all the fracture ends got united. At the final follow-up, the average active motions of the injured wrist were: 67.9° in flexion, 64.1° in extension, 21.2° in radial deviation and 52.2° in unlar deviation, respectively. The average grip strength was recovered to 31.3 kg, reaching up to 85.2% (from 66.7% to 100.0%) of the contralateral wrist; the average pinch force was recovered to 19.5 kg, reaching up to 89.3% (from 77.8% to 100.0%) of the contralateral wrist. At the last follow-up, the Mayo wrist function scores averaged 97.5 (from 95 to 100) and all the 8 cases were excellent. The VAS pain score of the wrist averaged 0.88 (from 0 to 2).Conclusion:In the treatment of fresh undisplaced scaphoid lumbar fractures, navigation with a Tianji orthopedic robot can be used to visualize percutaneous minimally invasive screw fixation so that accurate positioning and precise screw placement are ensured, leading to rapid rehabilitation.

Abstract Objective The objective of the present study was to evaluate the clinical and radiographic results of our series regarding ulnar shortening osteotomy, as well as to briefly review the pathology, indications and surgical options of ulnocarpal conflict. Methods We performed a retrospective analysis of consecutive patients who were treated with ulnar shortening osteotomy between January 2012 and June 2017 at our hospital. We clinically evaluated pain, articular range of motion, grip strength and functional outcomes using the quick-DASH questionnaire. We radiographically measured the pre- and postoperative ulnar variance and the shortening performed. Results We identified eight operated patients, and it was possible to evaluate seven of them. Pain decreased in this population (visual analogue scale [VAS] score changed from 7 to 2.6, p< 0.05), there was a decrease in quick-DASH (64 to 28, p< 0.05) and we found a decrease in the articular amplitude ∼ 7° for flexion (p= 0.2), and of 5.5° for supination (p= 0.3), as well as decreasing grip strength to about 86% on the contralateral side (p= 0.07). The ulnar variance changed from a mean of + 5.5 mm to - 1.1 mm (p< 0.05). Two out of 8 patients (25%) presented plaque-related symptoms and one of them underwent a new intervention to extract the material. Conclusions Ulnar shortening osteotomy is an effective surgical procedure both in the treatment of ulnocarpal conflict and in the discharge of the ulna. The results presented agreement with other results published in the literature, with good clinical and radiographic results.

Rotational Shift of Proximal Carpal Row and it's Correlation with Global Wrist Joint Laxity

Introduction: As the wrist moves to ulnar deviation, theproximal carpal row undergoes radial translation, dorsalrotation and supination. Similarly, the radial deviationinvolves ulnar translation of the proximal carpal row, its volarrotation and pronation. These combined movements of theproximal carpal row are called rotational shift of the carpus.Study aimed to quantify the rotational shift of the proximalcarpal row during ulnar or radial deviation of the wrist.Material and methods: The proposed study was a prospectivestudy conducted in the Department of Orthopedics, RMCH,Bareilly, UP comprising 100 healthy volunteers with equal sexration who never had any symptoms pertaining to their wristjoint. PA and lateral radiograph were obtained in full radialand ulnar deviation. A custom-made positioning device wasused to ensure proper placement of the hand and wrist duringthe examination.Results: In the present study, we observed that theradioscaphoid angle in radiation deviation varied from 50to 85 degree with mean of 68.96 degree. Radioulnate anglein radial deviation varied from -2 to 45 degree with mean of17.79 degree. Radioscaphoid angle in ulnar deviation variedfrom 10 to 70 degree with mean of 39.97 degree. Radioulnateangle in ulnar deviation varied from -3 to -38 degree withmean of -17.15 degree.Conclusion: Within the limitations of the present study, itcan be concluded that the ulnar deviation of the wrist is seento cause radial translation ad dorsal rotation of the proximalcarpal row. Similarly, the radial deviation was seen to causeulnar translation and volar rotation of the proximal carpal row.

The microscopic surgery can protect the blood supply, can also repair intra-articular ligament, cartilage injury, and along with all the dislocation, fracture of carpal bone fixed effectively. OBJECTIVE: To retrospectively analyze clinical effects of distal radial anatomical locking plate for complex distal radius fractures by joint arthroscopy. METHODS: Totally 19 patients with complex distal radius fractures, who were treated in the Department of Trauma and Hand Surgery, Sichuan Provincial Orthopedic Hospital from September 2016 to May 2018, were included in this study. According to AO classification, there were B2 type in 1 patient, B3 type in 2 patients, C1 type in 5 patients, C2 type in 7 patients and C3 type in 4 patients. All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. Open reduction and internal fixation with anatomical locking plate of distal radius assisted by wrist arthroscopy were used to repair the intercarpal interosseous ligaments and triangular fibrocartilage complex, and to fix the wrist fracture. At 1 year after treatment, the range of wrist motion, grip strength, radial height, palm inclination angle and ulnar angle were compared with the healthy side, and the functional evaluation was conducted with Mayo wrist score. RESULTS AND CONCLUSION: (1) Nineteen patients received postoperative follow-up. The healing time of distal radius was 5-12 months, with an average of 7 months. (2) At 1 year after surgery, no significant difference was detected in the range of wrist motion, grip strength, radial height, palm inclination angle and ulnar angle (P > 0.05). (3) The Mayo wrist score was excellent in 9 cases, good in 8 cases, and average in 2 cases, with the excellent and good rate of 90%. (4) Treatment of complex distal radius fractures with distal radial anatomical locking plate by wrist arthroscopy can accurately restore the stability of the joint, and simultaneously repair the fracture with cartilage damage and intra-articular ligament, which is conducive to early functional exercise and has a satisfactory effect.

3d printed orthopedic cast combined withzicaooil promotes the recovery of wrist joint function after distal radius fracture / 中国组织工程研究

BACKGROUND: 3D printing external fixation fixture can make individualized external fixation scheme for fracture patients and is easy to wear. Zicao oil (a Chinese traditional medicine oil) for trauma treatment has the effect of reducing swelling and removing blood stasis to assist the rehabilitation treatment of fracture. The combination of the two could benefit the rehabilitation of patients with fracture conservative treatment. OBJECTIVE: To investigate the clinical application value of the 3D printed orthopedic cast combined with Zicao oil in the treatment of distal radial fracture, hoping to provide a basis for the further study of a combined Chinese and western medicine treatment scheme for the recovery of wrist function after distal radius fractures. METHODS: Sixty-four patients with distal radial fracture were selected and randomly divided into two groups. Patients in the trial group received 3D-printed cast combined with Zicao oil treatment after manual reduction. Patients in the control group received traditional splint cast combined with Zicao oil after manual reduction. The Jakim scoring for distal radial fracture treatment, as well as pain degree, swelling degree, wrist range of motion, grasping ability and deformity degree were evaluated and compared 2 weeks after removal of external fixation in both groups. RESULTS AND CONCLUSION: (1) The excellent and good rate was 94% in the trial group and 78% in the control group. There was significant difference between the two groups (P < 0.01). (2) At 2, 4, 8 and 14 days after treatment, the scores of wrist range of motion and visual analogue scale were significantly better than those before treatment (P < 0.01). At different time points after treatment, the scores of wrist range of motion and visual analogue scale in the trial group were significantly better than those in the control group (P < 0.05). (3) The swelling degree of the trial group was better than that of the control group 2, 4, 8 and 14 days after treatment (P < 0.05). (4) The results show that 3D printed cast combined with Zicao oil is effective in the treatment of distal radius fracture, can effectively improve the function of wrist joint, reduce the pain of patients and improve the quality of rehabilitation.
