Phalangeal microgeodic syndrome: case report of a young woman treated with pentoxifylline.

Phalangeal microgeodic syndrome (PMS) is a rare osteolytic disorder of unknown etiology that typically affects children up to 15 years old during colder months. Transient peripheral circulatory impairment probably underlines its pathogenesis. Conservative treatment with eviction of cold exposure is often successful. We report the case of a young woman presenting with joint pain in her feet, along with toe discoloration and redness, where a diagnosis of PMS was established based on magnetic resonance imaging findings and exclusion of other differential diagnostic entities. Pharmacological treatment was deemed necessary for symptomatic relief, but a trial of calcium channel blocker (CCB) was not tolerated by the patient. The patient was then started on pentoxifylline, with significant clinical improvement.

Finite Element Analysis of the Mechanical Strength of Phalangeal Osteosynthesis Using Kirschner Wires.

Background: Kirschner wire (K-wire) fixation is widely used to repair metacarpal and phalangeal fractures. In this study, we simulated K-wire osteosynthesis of a 3-dimensional (3D) phalangeal fracture model and investigated the fixation strength at various K-wire diameters and insertion angles to clarify the optimal K-wire fixation method for phalangeal fractures. Methods: The 3D phalangeal fracture models were created by using computed tomographic (CT) images of the proximal phalanx of the middle finger in five young healthy volunteers and five elderly osteoporotic patients. Two elongated cylinders representing K-wires were inserted according to various cross-pinning methods; the wire diameters were 1.0, 1.2, 1.5 and 1.8 mm, and the wire insertion angles (i.e. the angle between the fracture line and the K-wire) were 30°, 45° and 60°. The mechanical strength of the K-wire fixed fracture model was investigated by using finite element analysis (FEA). Results: The fixation strength increased with increasing wire diameter and insertion angle. Insertion of 1.8-mm wires at 60° achieved the strongest fixation force in this series. Fixation strength was generally stronger in the younger group than the elderly group. Dispersion of stress to cortical bone was a critical factor to increase fixation strength. Conclusions: We developed a 3D phalangeal fracture model into which we inserted K-wires; using FEA, we clarified the optimal crossed K-wire fixation method for phalangeal fractures. Level of Evidence: Level V (Therapeutic).

Objective:To investigate the effect of absorbable material internal fixation in the treatment of phalanx fracture and its effect on the complications related to hypersensitive C-reactive protein (hs-CRP), interleukin-10 (IL-10), adrenocorticotropic hormone (ACTH) and foreign body reaction.Methods:The clinical data of 98 patients with phalangeal fracture in Huishan District People′s Hospital of Wuxi City from January 2018 to January 2020 were divided into absorbable group (49 cases, treated with absorbable material internal fixation) and microplate group (49 cases, treated with minimally invasive plate internal fixation). The rates of excellent and good treatment, operation conditions, serum inflammatory stress response indexes levels before and 1 d and 1 week after surgery were compared, and recovery at 3 and 6 months after surgery, the incidence of complications and the degree of treatment satisfaction were counted.Results:The rates of excellent and good treatmentin the absorbable group were higher than that in the micro plate group: 95.92%(47/49) vs. 81.63%(40/49), χ2 = 5.02, P<0.05. The duration of operation in the absorbable group was longer than that in the microplate group: (43.28 ± 12.18) min vs. (31.29 ± 11.69) min; and the duration of hospital stay, fracture healing time and recovery time were shorter than those in the microplate group: (4.09 ± 1.18) d vs. (6.89 ± 2.12) d, (4.35 ± 1.05) weeks vs. (5.69 ± 1.38) weeks, (4.89 ± 1.10) d vs. (6.20 ± 2.01) d; the differences were statistically significant ( P<0.05). The levels of serum hs-CRP, IL-10 and ACTH in absorbable group were lower than those in microplate group at 1 d and 1 week after surgery ( P<0.05). At 3 and 6 months after surgery, the range of motion of metacarpophalangeal joint in the absorbable group was greater than that in the microplate group, and the loss of grip strength of the healthy side was less than that in the microplate group ( P<0.05). The incidence of complications in absorbable group was lower than that in microplate group: 6.12%(3/49) vs. 20.41%(10/49), χ2 = 4.35, P<0.05. Conclusions:The absorbable material internal fixation can achieve good results in the treatment of phalanx fracture, the postoperative recovery is fast, the incidence of complications is lower.

Florid Reactive Periostitis of the Proximal Phalanx-Case Report and Literature Review.

Florid reactive periostitis is a benign and rare lesion that is a recurrent diagnostic problem. Its etiopathogenesis remains unknown. Florid reactive periostitis consists of a fibrotic, cartilage-producing tumor accompanied by an aggressive inflammatory periosteal and soft tissue reaction. It typically occurs in adolescents and young adults, mostly female; it often affects hand and foot bones, and it may occur in long bones. Its diagnosis remains a major challenge due to the vast possibility of differential diagnoses. Therefore, careful clinical, radiological, and pathological evaluation is required to establish a proper diagnosis. We report the case of a patient with florid reactive periostitis in the proximal phalanx of the right index finger, who underwent surgical excision with a wide margin, from the second ray to the proximal third of the second metacarpal bone, and evolved without complications, with satisfactory range of motion and strength.

[Different mini skin flaps in repairing finger soft tissue with bone defect].

OBJECTIVE: To explore surgical methods and clinical effects of three different types of mini skin flap transplantation for repairing finger soft tissue with bone defect. METHODS: Thirty-three patients with finger soft tissue or bone defect were treated from December 2014 to October 2016, including 24 males and 9 females aged from 21 to 52 years old with an average of (36.42±5.70) years old, and soft tissue defect area ranged from 1.3 cm×1.8 cm to 2.3 cm×4.2 cm. According to damage degree, nature and patients' options, 15 finger of 15 cases were adopted retrograde dorsal metacarpal artery perforators fascia flap, 10 fingers of 9 cases were treated with free foot artery descending branch wrist skin flap, 9 fingers of 9 cases were treated with free the second toe details phalanges compound flap. Survival rate, postoperative complications and finger function assessed by Dargan functional criteria at the latest follow up were observed. RESULTS: All flaps were survived, both of donor site and recipient site were without deep infected. The donor site of one patient occurred necrotic, and the distal donor site of one patient occurred surface necrotic, then healed by active dressing change. All patients were followed up from 6 to 16 months with an average of(8.34±1.28) months. Two points of finger recognition were restored between 8 and 12 mm with an average of (8.84±0.43) mm, and the appearance, texture and sensory functions of skin flap were restored. No obvious complications were observed on the donor site. According to Dargan function evaluation of finger joints, 18 patients got excellent results, 14 moderate and 1 good. CONCLUSIONS: Three kinds of mini skin flap could receive good results in repairing soft tissue of finger or bone defect. Reverse dorsal metacarpal artery perforator fascia flap is not necessary with anastomosing blood vessels and has advantages of safe, simple and high survival rate. Descending branch of superior cutaneous branch of free ulnar artery could cut multiple other perforator flaps simultaneously, and the scar is small and hidden. Dissociated the second toe combined metatarsal phalangeal flap could repair shape and function of finger to the maximum extent and donor site is hidden.

Radiographic changes of the distal phalangeal tuft of the hands in subjects with systemic sclerosis. Systematic review. / Cambios radiográficos del penacho de la falange distal de las manos en pacientes con esclerosis sistémica. Revisión sistemática.

OBJECTIVE: To determine abnormal plain radiograph findings of the distal phalanx tuft of the hand (DPTH) associated with systemic sclerosis in adults. METHODS: A systematic review was developed following the parameters of the PRISMA guidelines in databases: MEDLINE, EMBASE, BIREME, Scielo, Google Scholar and others including as primary outcomes alterations of DPTH (erosions, resorption, sclerosis and proliferation) detected by simple radiography in subjects with systemic sclerosis. The prevalence of radiographic findings was synthesized using the fixed effects model. The statistical associations were expressed in terms of relative risk or odds ratio with their respective confidence intervals and p values. RESULTS: Twenty-two observational studies were included; the prevalence of DPTH resorption was 28.3% (95% CI: 0.256-0.312; p < .001); I2=80.4%, the prevalence of calcinosis was 15.6% (95% CI: 0.113-0.210; p < .001); I2=0%. No study reported proliferation or erosions and only one study described sclerosis of DPTH in 5 individuals. CONCLUSIONS: Resorption and calcinosis of DPTH are the characteristic radiographic findings in patients with systemic sclerosis. However, new studies with greater methodological strength are needed to establish associations between these phenomena and their presence in other connective tissue diseases.

Hand Fractures

Hand fractures are the second most common fracture in the upper extremities after the distal radius, and patients with these injuries may be experienced in hand surgery clinics. On the other hand, during the treatment of hand fractures, complications can occur due to complex functions of the hand and small-sized injuries to the bone and soft tissues. This review focused on the principles of management of these fractures, including injury mechanism, evaluations and recent treatment options. Minimally invasive surgery in various types of hand fractures, including the phalanx and metacarpal bone, is preferred because early mobilization after surgery has been emphasized to reduce complications, such as stiffness.

Objective To discuss the clinical curative effect between dynamic external fixator (DEF) and hand orthosis (HO) in patients with middle phalanx pars basilaris fracture. Methods A total of 143 patients with middle phalanx pars basilaris fracture were selected from January 2015 to April 2016. The patients were divided into 2 groups according to the patients′select: DEF group (83 cases) and HO group (60 cases). The patients in DEF group were treated with DEF fixation under local nerve block anesthesia of digital root, and the patients in HO group were treated with HO fixation after manual repositioning. The fracture healing time and complications were observed. All patients were functionally trained and evaluated by total active motion (TAM). Results The patients were followed up for 8 to 16 weeks, with an average of 12 weeks. There was no statistical difference in fracture healing time between 2 groups (P＞0.05). All patients had postoperative pain, but the incidence of postoperative pain after removing DEF or HO in DEF group was significantly lower than that in HO group: 26.51% (22/83) vs. 46.67% (28/60), and there was statistical difference (P＜0.05). No redislocation or subluxation occurred after removal of external fixation in 2 groups. X-ray follow-up showed that the incidences of mild traumatic osteoarthritis, mild angulation deformity and mild lateral instability in DEF group were significantly lower than those in HO group: 6.02% (5/83) vs. 23.33% (14/60), 3.61% (3/83) vs. 33.33% (20/60) and 1.20% (1/83) vs. 26.67% (16/60), and there were statistical differences (P＜0.05). The excellent and good rate of TAM in DEF group was significantly higher than that in HO group: 83.13% (69/83) vs. 63.33% (38/60), and there was statistical difference (χ2=7.25, P＜0.01). Conclusions The clinical curative effect of DEF fixation is better than HO fixation in patients with middle phalanx pars basilaris fracture.

CONCLUSÃO: O presente estudo apresentou uma nova técnica, simples e facilmente reprodutível, para as lesões das pontas de dedos com resultados satisfatórios e baixa taxa de complicações.

Massa óssea por ultrassonografia quantitativa de falanges em jovens praticantes de karatê / Bone mass by quantitative ultrasound of finger phalanges in young karate practitioners

RESUMO Objetivo: Avaliar a massa óssea pela ultrassonografia quantitativa de falanges em jovens praticantes de karatê em relação a um grupo controle. Métodos: Amostra constituída por 162 praticantes de karatê (52 meninas) e 326 controles escolares (110 meninas) saudáveis, de 6 a 16 anos de idade, do oeste do Paraná. Foram avaliados peso, estatura, índice de massa corporal (IMC), Amplitude Dependent Speed of Sound (AD-SoS) e Bone Time Transmission (BTT), e os valores de IMC, AD-SoS e BTT transformados em escore Z. Aplicaram-se testes de Mann-Whitney, qui-quadrado ou Exato de Fisher e regressão linear múltipla, sendo significante p≤0,05. Resultados: Para ambos os sexos, os praticantes de karatê apresentaram valores superiores do escore Z do BTT comparados aos controles. Quanto à AD-SoS, as meninas do grupo de controle apresentaram valor absoluto e de escore Z superiores aos apresentados pelas praticantes de karatê do mesmo sexo. Ao avaliar a frequência relativa e absoluta de acordo com o escore Z do BTT em ambos os grupos, os meninos praticantes de karatê apresentaram maior frequência de massa óssea adequada. Nas meninas praticantes de karatê, a idade apresentou poder de explicação de 42% na variação da AD-SoS e o peso de 45% na variação do BTT. Nos meninos praticantes de karatê, a idade apresentou poder de explicação de 26% na variação da AD-SoS e a estatura 36% na variação do BTT. Conclusões: Nesse grupo de crianças e adolescentes, independentemente do sexo, os praticantes de karatê apresentaram maior massa óssea em relação ao grupo controle, sendo o BTT mais sensível para essa avaliação.

ABSTRACT Objective: To evaluate bone mass by quantitative ultrasound of the phalanges in young karate practitioners compared to a control group. Methods: Sample composed of 162 karate practitioners (52 females) and 326 healthy controls (110 females) aged 6 to 16 years old, in Western Paraná (Southern Brazil). Weight, height, BMI, amplitude-dependent speed of sound (AD-SoS) and bone transmission time (BTT) were evaluated. BMI, AD-SoS and BTT values were converted to Z scores. Mann-Whitney, chi-square or Fisher Exact tests and multiple linear regression were applied, with significance level set at p≤0.05. Results: Both genders showed higher values of BTT as Z scores when compared to control group. Females from the control group had higher AD-SoS values (m/s and Z score) compared to female karate practitioners. When relative and absolute frequencies were assessed according to BTT Z score in both groups, male karate practitioners' bone mass was shown to be adequate more frequently. In female practitioners, age and weight were independent predictors of AD-SoS (R2=0.42) and BTT (R2=0.45), respectively. Among male karate practitioners, age was related to 26% of AD-SoS variances and height was responsible for 36% of BTT variances. Conclusions: Children and adolescents who practice karate were shown to have more bone mass in comparison to the control group, regardless of gender. BTT was more sensitive for this evaluation.
