Objective:To explore the clinical effect of repairing interphalangeal joint defect of hand with free transfer of part of the 2nd metatarsophalangeal joint tissue flap precisely cut with the aid of digital 3D printing technology.Methods:From December 2016 to December 2020, 7 patients with partial joint defects of proximal interphalangeal joints of fingers were treated in Department of Hand and Foot Surgery, Shunde Hospital Affiliated to Guangzhou Medical University(Foshan Shunde Lecong Hospital). Before surgery, three-dimensional data of hand and foot bones were collected, and the 3D printing model was used to simulate the operation in vitro. During the operation, the first dorsal metatarsal artery-the 2nd dorsal metatarsal artery was used as the pedicle, and the 2nd metatarsophalangeal joint composite tissue flap with a required size was harvested with the assistance of the navigation template to tranfer and repair the small joint defects of hand. All 7 cases entered follow-up at outpatient and telephone. Results:All 7 cases survived. Postoperative follow-up was 3-24(mean 9.5) months, Range of motion of the repaired interphalangeal joint was (56 ± 6)°; According to the Evaluation Standard of Thumb and Finger Reconstruction Function of the Society of Hand Surgery of the Chinese Medical Association, 2 cases were excellent, 4 cases were good, and 1 case was poor.Conclusion:Transfer of the free 2nd metatarsophalangeal joint tissue flap assisted by 3D printing technology in repair of the small joint defect of the hand can accurately harvest the tissue flap, which is clinically reliable.

Modified transfer of proximal interphalangeal joint from the second toe for reconstruction of proximal interphalangeal joint of finger / 中华显微外科杂志

Objective:To evaluate the clinical effect of the modified transfer of the proximal interphalangeal joint (PIPJ) from the second toe in the treatment of a finger PIPJ defect.Methods:A total of 13 patients with finger PIPJ defects caused by traumatic injury were enrolled from May, 2017 to March, 2020. All the PIPJ defects had primary traumatic repairs. The causes of injury: 5 patients were caused by strangulation, 4 by chainsaw, 2 by strangulation and 2 by crushing. Of which, 7 patients had index finger injury, 3 middle fingers and 3 ring fingers. The operations were carried out 3-7 months after the first stage of treatment. The grafting of the PIPJ of the second toe with modified vascular anastomosis were performed. The ipsilateral second toe was taken in 10 patients, and the contralateral second toe in 3 patients. The grafted joints all carried observation skin islands, with an area of 1.0 cm×1.5 cm-1.0 cm×2.0 cm. All the secondary bone defects in the donor site of the toe were reconstructed with iliac bone grafts, and the length of the iliac bone strips was 4.0-6.0 cm. At the same time, the island flap on the fibular side of the great toe was removed and repaired at the donor site, with an area of 1.1 cm×1.6 cm - 1.1 cm×2.1 cm. Early postoperative rehabilitation was performed. The patients were followed-up through outpatient visits, telephone and WeChat interviews.Results:All the 13 finger PIPJ and donor site island flaps survived. Bone healing were observed in all patients with the healing time in 8-12(average 10) weeks. Three patients with severe adhesion of joint and tendon were treated with secondary release. All the patients were followed-up for 10 - 18 months without degeneration of PIPJ. Active range of motion of PIPJ ranged: 45°-90° in flexion and 0°-10° in extension, the average motion activity was 66.3°. Seven patients were in excellent, 4 in good and 2 in fair, according to the function assessment proposed by the Society of Hand Surgery of Chinese Medical Association. The appearance on donor site was good and the walking was normal in the longterm follow-up. Only one linear scar was left in the ilioinguinal donor site without obvious discomfort.Conclusion:It was possible to use the modified transfer of the PIPJ from the second toe in the treatment of a finger PIPJ defect. An iliac bone graft and an island flap of the first toe transfer can preserve the appearance and function of the toes.

Value of ultrasonography in diagnosis of closed volar plate injury of proximal interphalangeal joint / 中华超声影像学杂志

Objective:To evaluate the role of high frequency ultrasonography in diagnosis of closed volar plate injury of proximal interphalangeal joint.Methods:From May 2015 to may 2021, 41 patients with acute closed volar plate injury confirmed by Department of Hand and Foot Surgery of the Provincial Hospital Affiliated to Shandong First Medical University were examined by high frequency ultrasonography. The sonographic features were analyzed and classified.Results:High frequency ultrasonography could not only clearly show the thickness, shape and echo of volar plate, but also the degree of injury and avulsion fracture of volar plate, according to which the closed volar plate injury could be divided into three types: A, B and C. Type A(13 cases): Avulsion fracture of the middle phalangeal base was found with volar plate rupture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and avulsion fracture was found at the distal end of the volar plate. Type B(11 cases): Complete rupture of the volar plate attachment of the middle phalangeal base was found without avulsion fracture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and the end of the volar plate contracted and thickened. Type C(17 cases): Tear of the volar plate was found, the sonogram showed enlarging volar plates, heterogeneous internal echo, and liquid dark area was visible in some cases. The average thickness of the three types of closed volar plate injury of the proximal interphalangeal joint measured by ultrasound was (0.33±0.05)cm, and the average thickness of the volar plate at the same position of the corresponding finger on the opposite side was (0.22±0.03)cm. There was significant difference between the two groups ( t=7.864, P=0.006). Conclusions:High frequency ultrasonography is the preferred imaging examination method for the diagnosis of closed volar plate injury in proximal interphalangeal joint, which has an important guiding significance for the selection of clinical treatment.

Modified Transosseous Wiring Technique for Neglected Fracture–Dislocation of the Proximal Interphalangeal Joint

BACKGROUND: Fracture–dislocation of the proximal interphalangeal (PIP) joint of the finger is challenging due to the high risk of stiffness. The purpose of this study is to evaluate the clinical and radiological results of a modified transosseous wiring technique for the management of chronic fracture–dislocations of the PIP joint. METHODS: Ten patients (nine men and one woman; mean age, 38.3 years; range, 21 to 69 years) with neglected fracture–dislocation of the PIP joint were included. The mean duration from injury to operation was 14.7 weeks (range, 3 to 66 weeks). The dorsolateral approach and extension block pinning were used to reduce dislocation. After thorough debridement of the scar tissues in the dorsal dead space and the fracture site, the reduction was maintained with transosseous wiring. Radiologic evaluations of bone union and arthritic changes and clinical evaluations (range of motion of the PIP joint and Disabilities of the Arm, Shoulder and Hand [DASH] score) were performed. The mean follow-up period was 12.9 months (range, 12 to 19 months). RESULTS: All patients demonstrated evidence of radiographic healing within a mean healing time of 6 weeks (range, 4 to 10 weeks); however, one had a widened gap and one had an early arthritic change. The mean range of motion in the PIP joint was 81° (range, 50° to 105°). The mean DASH score was 21.6 (range, 7.5 to 35.8). CONCLUSIONS: For chronic fracture–dislocation of the PIP joint, transosseous wiring with direct curettage and optimal bone purchase can provide satisfying outcome.

Treatment of Neglected Proximal Interphalangeal Fracture Dislocation Using a Traction Device: A Case Report

This paper reports the use of a traction device for the treatment of neglected proximal interphalangeal fracture dislocations. A 44-year-old man with a fracture dislocation of a right ring finger proximal interphalangeal joint was admitted 17 days after the injury. Closed reduction and external fixation were performed using a dynamic traction device and C-arm under a brachial plexus block. Passive range of motion exercise was started after two weeks postoperatively and active range of motion exercise was started after three weeks. The traction device was removed after five weeks. No infection occurred during the traction period. No subluxation or displacement was observed on the X-ray taken two months postoperatively. The active range of motion of the proximal interphalangeal joint was 90°. The patient was satisfied with the functional result of the treatment with the traction device. The dynamic traction device is an effective treatment for neglected fracture dislocations of the proximal interphalangeal joint of a finger.

Collagenase Clostridium Histolyticum Injection for Dupuytren Contracture: 2-Year Follow-up

BACKGROUND: Dupuytren disease is characterized by the development of palmar fibrous tissue that can lead to fixed flexion contracture (FFC) and contribute to functional loss of the involved digits. Our goal was to investigate rates of contracture resolution and recurrence in patients who underwent enzymatic fasciotomy for Dupuytren contracture consisting of collagenase clostridium histolyticum (CCH) injection followed by passive manipulation combined with splinting and home-based therapy. METHODS: We prospectively enrolled 34 patients (44 metacarpophalangeal [MCP] and 33 proximal interphalangeal [PIP] joints) treated by one orthopaedic hand surgeon between November 2010 and November 2014. On day 1, CCH was injected into a palpable fibrous cord of the involved fingers. The next day, the finger was passively extended to its maximal corrective position. FFC was measured for each joint before injection and immediately after manipulation. Patients were instructed to wear an extension splint at night and perform stretching exercises at home and were re-evaluated at 6 weeks, 4 months, 1 year, and 2 years. Resolution was defined as improvement of contracture to ≤ 5° of neutral. Recurrence was defined as an increase in FCC of ≥ 20° after treatment. RESULTS: Immediate contracture resolution occurred in 42 of 44 MCP joints (p < 0.001), improving from 50° to 1.5°, and in 14 of 33 PIP joints (p = 0.182), improving from 44° to 16°. Four joints had recurrence within 6 weeks. Of the 48 joints with minimum 4-month follow-up (mean, 26 months), 12 had recurrence at 2-year follow-up (MCP, 6; PIP, 6). At 2-year follow-up, MCP and PIP contractures measured 17° and 35.5°, respectively. Older age and multiple digit involvement were associated with higher recurrence rates. CONCLUSIONS: CCH offers a safe, nonoperative option to correct FCC in Dupuytren disease with greater success for MCP joints compared to PIP joints. There is a tendency of reoccurrence within 2 years of treatment. Further investigation is needed to determine optimal timing of repeat CCH injection to improve upon or extend the period of contracture resolution.

Three Cases of Pachydermodactyly / 대한피부과학회지

Pachydermodactyly (PDD) is a rare, benign form of digital fibromatosis that is characterized by asymptomatic soft tissue swellings on the back and side of the proximal interphalangeal joint areas of the fingers. We report three cases of young male patients who presented with bilateral swelling of the fingers. Histopathologic examination showed epidermal hyperplasia with acanthosis and hyperkeratosis. Collagen fibers in the reticular dermis were thickened and irregularly arranged, and deposition of mucin in the dermis was observed. Since pachydermodactyly usually affects adolescent males with joint swelling, it is often confused with rheumatologic diseases. Here, we report three cases diagnosed with pachydermodactyly based on clinical manifestations and histopathological examination.

Transferencia articular vascularizada: Reporte de caso / Free vascularized joint transfer: Case report

La articulación interfalángica proximal otorga la mayor contribución al arco total de movimiento digital, por lo tanto, la pérdida de movimiento normal de la articulación tiene un impacto considerable en la función y fuerza de agarre. El único método que asegura la preservación a largo plazo de la arquitectura cartilaginosa, así como una curación ósea rápida tras destrucción articular traumática o patológica es la transferencia articular vascularizada. Es definida como un trasplante articular parcial o completo con preservación o restauración inmediata del flujo de sangre. Se presenta el caso de un masculino de 20 años, con antecedente de trauma contuso-cortante en borde cubital de 3er dedo de mano izquierda zona II a quien se realiza cierre primario. Siete meses después a presentó deformidad articular e incapacidad funcional para la flexión de articulación interfalángica proximal. Se realizó procedimiento de reconstrucción articular, mediante transferencia articular vascularizada de 2° dedo del pie derecho. Posteriormente se dio seguimiento a través de consulta externa a las 2, 4, 6 y 8 semanas, 6 meses y 12 meses. A los 6 meses fue sometido a capsulotomía, liberación de placa volar, retiro de placas de osteosíntesis y adelgazamiento de isla cutánea. Se alcanzaron rangos de movimiento pasivo de extensión de 85° y activo de 70°. En base a la experiencia de nuestro centro se demuestra que el uso de transferencia articular en 2 etapas de reconstrucción, se pueden mantener rangos de movimiento tanto activo como pasivo suficiente para una adecuada función.

The proximal interphalangeal joint provides the greatest contribution to the total arc of digital movement, therefore, the loss of normal movement of the joint has a considerable impact on function and grip strength. The only method that ensures the long-term preservation of the cartilaginous architecture, as well as a rapid recovery of traumatic or pathological joint destruction, is vascularized joint transfer. It is defined as a partial or complete partial transplant with preservation or immediate restoration of blood flow. We present the case of a 20-year-old man, with a history of contusive-cutting trauma on the ulnar border of the third finger of the left hand, area II, who underwent primary closure. Seven months after the presentation of the joint and functional disability for proximal interphalangeal joint flexion. A joint reconstruction process was performed, by means of a vascularized joint transfer of the 2nd toe of the right foot. Subsequently, follow-up was carried out through the outpatient clinic at 2, 4, 6 and 8 weeks, 6 months and 12 months. At 6 months he was subjected capsulotomy, volar plate release, osteosynthesis plates removal and cutaneous island thinning. Ranges of passive movement of extension of 85° and active of 70° were reached. Based on the experience of our center, it is shown that the use of the transfer was made in 2 stages of reconstruction, the range of both active and passive movements can be maintained for an adequate function.

Clinical Results of Dynamic External Fixation for Proximal Interphalangeal Joint Fracture Dislocation

PURPOSE: We evaluated clinical outcomes after treating patients with proximal interphalangeal (PIP) joint fracture-dislocation with dynamic external fixator with which early joint motion can be undertaken to prevent joint stiffness effectively and fixate joints firmly. METHODS: Dynamic external fixators were applied for 20 fracture-dislocation of the PIP joints in 19 patients. The joints involved were 2nd PIP joint in two patients, 3rd PIP joint in three patients, 4th PIP joint in five patients, 5th PIP joint in eight patients. One patient had both 3rd and 4th PIP joint fracture-dislocation. Surgery was performed at least within four weeks. The mean age of the patients was 30.5 years (range, 15-54 years) and the mean follow-up duration was 1.85 years (range, 1-2.3 years) years. All patients were clinically and radiologically assessed on an outpatient basis after being discharged. RESULTS: At the final follow-up, the mean range of motion of PIP joints in flexion was 100.1° (flexion range, 88°-110°), the mean extension lag was 3.0° (extension range, 0°-10°), and the mean visual analogue scale score was 0.8. On anterior-posterior and lateral radiographs, congruity of the joint was satisfactory and 1 mm step off was present in three cases. CONCLUSION: We attained satisfactory clinical outcomes on the recovery of joint movement and joint congruity after treating PIP joint fracture-dislocation injury with dynamic external fixator.

Irreducible Open Dorsal Dislocation of the Proximal Interphalangeal Joint: A Case Report

Dorsal dislocation of the proximal interphalangeal joint is a common injury in the orthopedic department. In most cases, the joint is reduced simply by closed manipulation. However, in rare cases, the joint is not reducible by closed manipulation, therefore, surgery is required. We report on a case of irreducible open dorsal dislocation of the proximal interphalangeal joint which was surgically treated. Because the flexor tendon interposed between the head of the proximal phalanx and the base of the middle phalanx, we could reduce the joint only after repositioning of the flexor tendon.

Uso de férulas correctoras en la rigidez de la articulación interfalángica proximal como consencuencia de un traumatismo / Corrective splints in the stiffness of the proximal interphalangeal joint as a result of trauma

La pérdida de rango de movimiento pasivo (PROM) en las articulaciones interfalángicas de la mano es una secuela común tras lesiones traumáticas. A pesar de que el uso de férulas se ha convertido en una modalidad terapéutica ampliamente aceptada para mejorar el PROM, existe muy poca evidencia empírica que guíe en la prescripción de férulas. El presente estudio investiga el efecto del uso de férulas correctoras en contracturas en fexión de la articulación interfalángica proximal (IFP) de los dedos de la mano tras una lesión traumática. Diecisiete pacientes con una contractura en fexión de la IFP tras una lesión traumática como consecuencia de un accidente laboral participaron en este estudio experimental. Mediante un goniómetro digital se valoró el PROM de la articulación IFP de dichos pacientes y se les asignó de manera aleatoria a uno de los dos grupos de férulas. A los pacientes del grupo A se les colocó una férula de extensión dinámica de la IFP y a los del grupo B se les colocó una férula de extensión estática. El PROM de la articulación se volvió a valorar con un goniómetro en el momento en el que los pacientes recibieron el alta laboral. Los resultados indicaron mejorías signifcativas en ambos grupos en la corrección de la contractura en fexión (p<0,05). La diferencia entre los pacientes que usaron la férula dinámica frente a los que usaron la férula estática no fue estadísticamente signifcativa. Ambos tipos de férulas pueden ser recomendadas para el tratamiento de contracturas en fexión inferiores a 35º de la IFP tras una lesión traumática.

Reduced passive range of motion (PROM) of the interphalangeal joints of the hand is a common consequence after a traumatic injury.Although mobilizing splinting has become a rehabilitative approach widely accepted by therapists to improve PROM, limited empirical evidence is available to guide in its prescription. This study investigates the effect of corrective splinting on fexion contracture of the fnger proximal interphalangeal joints (PIP) after a traumatic injury of the hand. Seventeen patients with fnger fexion contracture of the PIP as a result of an industrial accident participated in the experimental study. The passive range of motion of the PIP joint was measured with a fnger goniometer and patients were randomly allocated to one of two splint programs. Subjects in group A were given dynamic extension splints, and subjects in group B were given static splints. PROM was re- assessed with a goniometer once the patient was discharged and started working again. Results indicated signifcant improvement in both groups in the correction of the fnger fexion contracture (p<0,05). Patients with dynamic fnger extension splints did not differ signifcantly from those with static splints in extension gains. Both types of splints can be recommended for fexion contractures of 35 degrees or less in the PIP joint after a traumatic injury.

Open Reduction and Internal Fixation for Intraarticular Volar Fractures of the Middle Phalanx in Proximal Interphalangeal Joint

PURPOSE: We report clinical and radiographic outcomes after internal fixation of intraarticular volar fractures of the middle phalanx base. METHODS: A retrospective review was conducted on 11 patients who had been treated with miniplate or screw for acute proximal interphalangeal joint fracture, after adjusting for the cases excluding severe comminuted or open fractures. The participants consisted of 9 males and 2 females, with average age of 43.7 years and with average follow-up period of 15.2 months. Bony union, change of articular side were examined through radiographs, and functional results were evaluated by means of the total active range of motion (TAM) and the disabilities of the arm, shoulder, and hand (DASH). RESULTS: Of 11 cases of a finger fracture, 7 cases were fixed by miniplate with screws and 4 cases by screws alone. At the final follow-up retrospection, the average range of proximal interphalangeal joint motion was 95degrees, the average TAM was 243.2degrees, and the average DASH score was 7.4. Average 2.8 months was spent from the finger fracture to bony union. There was no case of degenerative change. CONCLUSION: Open reduction and internal fixation with screws for acute intraarticular fractures of the middle phalanx base showed favorable results in our study and it could be one of recommendable treatment options.

External Dynamic Traction Device for Fracture of the Proximal Interphalangeal Joint of the Finger

PURPOSE: We evaluated the results of treatment for proximal interphalangeal joint fractures using an external dynamic traction device. MATERIALS AND METHODS: This study included nine patients with a proximal interphalangeal joint fracture. All patients were treated using an external dynamic traction device. At the mean follow-up of 10.1 months, the range of motion of the involved interphalangeal joint was measured. The clinical outcome was evaluated using Steel's scoring method. RESULTS: The average range of motion was 95degrees (range: 75degrees-110degrees). According to Steel's scoring method, three cases showed excellent results, two cases showed good results, and four cases showed fair results. CONCLUSION: The external dynamic traction device is useful and effective in treating proximal interphalangeal joint fractures. It enables reduction by ligamentotaxis and active and passive range of motion in the early stages of treatment.

Objective: There are many different techniques for finger arthrodesis our purpose is to compare the results of metarcophalangeal (MP) and proximal interphalangeal (PIP) joint arthrodesis, with tension band wire technique vs compression screw. Methods: Retrospective cohort study of patients with arthrodesis of the MP and PIP joint between 2006 and 2009, with a tension band wire technique (N = 28) and Mini-Acutrak screw (N = 29). We compared rates and times of union and the incidence of complications. Results: The union rate of the tension band group was 92.9 percent and 85.7 percent for the screw group, at 9.4 and 9.8 weeks respectively. The complications rate was 28.6 percent for tension band wire technique and 27.6 for the screw technique. The reoperation rate was 32.1 percent for the tension band wire technique and 3.6 percent for the screw group, with remove of 25 percent of the tension band. Discussion: Both surgical techniques had a similar rate of union and complications, but with significantly more re-operation to remove implants in the tension band group, which is an important factor to consider when choosing the surgical technique.

Reconstruction of Proximal Interphalangeal Joint Instability with Autogeneous Iliac Bone-Ligament-Bone Graft: A Case Report

We report the case of radial collateral ligament injury of proximal interphalangeal joint with bone defect by machinery grinder injury which was reconstructed using autogeneous iliac bone-ligament-bone graft. A heterodigital neurovascular island flap was performed to cover the skin defect. At 6 weeks follow-up, adduction stress endurance was enough to hold objects in usual life, but stiffness remained. The collateral ligament reconstruction using bone-ligament-bone graft is suggested for chronic instability or acute ligament defect of PIP joint.

Early Results of Hemicondylar Hamate Replacement Arthroplasty in Proximal Interphalangeal Fracture-Dislocation Injury

PURPOSE: We assessed early clinical and radiological results of hemicondylar hamate replacement arthroplasty in fracture-dislocation injury of the proximal interphalangeal joint. MATERIALS AND METHODS: From March 2007 to February 2008, four patients who had suffered from comminuted unstable fracture-dislocation of the proximal interphalangeal joint were treated by hemicondylar hamate replacement arthroplasty. All patients were male, and average age at operation was 21.5(range, 14~27) years. All cases showed subluxation of the proximal interphalangeal joint, and mean articular surface involvement was 50.8(range, 42.1~62.5)%. We clinically measured ROM, grip strength, pain of donor & recipient site, and radiologically assessed whether or not union, malalignment, or step-off occurred. RESULTS: Average follow-up period was 9.5(range, 6~14) months. Mean flexion contracture was 12.5 (range, 10~15)degrees in affected side and 0degrees in unaffected side. Mean further flexion was 92.5 (range, 85~100)degrees in affected side and 95.0 (range, 90~100)degrees in unaffected side. Mean VAS pain scores was 1.75 (range, 1~3) in recipient site and 1.25 (range, 0~2) in donor site. Mean grip strength was 11 (range, 8~15) lb in affected side and 14 (range, 10~17) lb in unaffected side. Union without malalignment was achieved in all cases. CONCLUSIONS: Early results of hemicondylar hamate replacement arthroplasty in the treatment of fracture-dislocation of the proximal interphalangeal joint showed satisfactory functional and radiological outcome.

Treatment of Fracture / 대한정형외과학회잡지

Pain, traumatic arthritis, joint stiffness and joint subluxation are common sequelae of fracture dislocations of the proximal interphalangeal joints of the finger. Many kinds of methods were used to treat fracture dislocation of the proximal interphalangeal joint. The prognosis is greatly influenced by the method and the time of treatment. Authors treated 4 cases of fracture dislocations of the proximal interphalangeal joint with 3 different method. For a case with small bony fragment, we used the extension block splint of McElfresh. For a old case, we used the volar plate arthroplasty mothod of Eaton. And for two cases with large bony fragment, we used the force couple splint method of Agee after open reduction and internal fixation. The results were satisfactory.

Volar Plate Arthroplasty of Proximal Interphalangeal Joint of Finger / 대한정형외과학회잡지

Pain, premature degenerative arthritis, stiffness and persisting subluxation are common sequalae of fracture dislocations of the proximal interphalangeal joints of the fingers. With disruption of greater than 40% of the volar articular surface of the middle phalanx, it is un- likely that congrous stable reduction can be achieved. And the most severe injuries are caused by longitudinal compression force, which drives the middle phalanx where the middle phalanx eventually comes to rest. Many authors had reported a variety of method for the treatment of the unstable fracture dislocation with no satisfactory results except Eaton(1980). In his ten years experience the volar plate arthroplasty for acute and chronic fracture dislocations got a good results with satisfactory range of motion and no pain on motion. Authors had been treated two cases of chronic fracture dislocations of the proximal interphalangeal joint with Eatons volar plate arthroplasty followed by good results in one year followed-up study.
