RESUMEN

Osteomyelitis of the phalanx caused by Candida species are rare. A 49-year-old female patient was admitted to an external center with a splinter injury of the third phalanx of the middle finger of her left hand about 45 days ago. She was referred to our clinic with persistent pain and discharge, despite four-week antibiotherapy. Debridement and curettage were performed and partial excision of the distal phalanx at an appropriate level was done. Her complaints gradually resolved postoperatively with prescribed antibiotics for the pathogen identified as Candida lusitaniae based on the intraoperative cultures. At her three-month follow-up visit, treatment yielded near-excellent results. To the best of our knowledge, this is the first case of osteomyelitis of the distal phalanx caused by Candida lusitaniae in the literature, highlighting the importance of definitive diagnosis and pathogen-specific treatment, rather than empirical treatment, to achieve favorable results with cure.

RESUMEN

INTRODUCTION: Soft-tissue mallet finger occurs due to loss of terminal extensor tendon secondary to rupture of distal phalanx. Although using noninvasive splints for 6-8 weeks is the gold standard for conservative treatment of closed soft-tissue mallet injuries, patient compliance is an important factor impacting on patient outcomes. In this study, we used a single Kirschner Wire (K-W) to fix the distal interphalangeal (DIP) joint in extension in those patients failed to comply with routine splinting. MATERIALS AND METHODS: In this prospective study, 190 patients with Doyle type 1 closed soft-tissue mallet finger deformity were included in four groups between 2011 and 2015. These groups were determined according to treatment modalities. Patients in the first group were treated with a finger splint (n = 109). Patients in the second group first received a finger splint and then K-W was applied due to lack of adequate compliance (n = 23). Patients in the third group were treated with K-W only (n = 47), and the fourth group did not accept surgical treatment nor conservative treatment (n = 11). After 20 weeks of follow up, we evaluated the results with functional measurements according to Crawford criteria and patient satisfaction. Additionally, the mid-term outcome was assessed with a follow-up at 2 years. RESULTS: At 20th week postoperatively, average DIP extension lag was 6 degrees (0-30) for the first group, 6.1 degrees (0-30) for the second group, 3.8 degrees (0-25) for the third group, and 17.3 degrees (7-30) for the fourth group. Total patient satisfaction was 85%, which was considered excellent or good. Swan neck deformity was observed in 11% of patients. Osteomyelitis and KW related complications were not observed. There were no statistically significant differences between short-term and mid-term results. CONCLUSION: Internal fixation via K-W may be a suitable treatment option compared to splint therapy for management of closed soft-tissue mallet finger in noncompliant patients. Using this treatment approach, the success rate for patients could satisfactorily be improved.

RESUMEN

BACKGROUND: The most common implant options for the metacarpophalangeal joint arthroplasty include silicone, pyrocarbon and metal-polyethylene. A systematic review of outcomes of silicone and pyrocarbon implants was conducted; however, a similar exercise for metal-polyethylene implants revealed a scarcity of published results and lack of long-term follow-up studies. The aim of the present work is to test the hypothesis that the magnitude of metacarpophalangeal joint cyclic loads generates stress and strain behaviour, which leads to long-term reduced risk of metal-polyethylene component loosening. METHODS: This study was performed using synthetic metacarpals and proximal phalanges to experimentally predict the cortex strain behaviour for both intact and implanted states. Finite element models were developed to assess the structural behaviour of cancellous-bone and metal-polyethylene components; these models were validated by comparing cortex strains predictions against the measurements. FINDINGS: Cortex strains in the implanted metacarpophalangeal joint presented a significant reduction in relation to the intact joint; the exception was the dorsal side of the phalanx, which presents a significant strain increase. Cancellous-bone at proximal dorsal region of phalanx reveals a three to fourfold strain increase as compared to the intact condition. Interpretation The use of metal-polyethylene implant changes the strain behaviour of the metacarpophalangeal joint yielding the risk of cancellous-bone fatigue failure due to overload in proximal phalanx; this risk is more important than the risk of bone-resorption due to the strain-shielding effect. By limiting the loads magnitude over the joint after arthroplasty, it may contribute to the prevention of implant loosening.

RESUMEN

INTRODUCTION/AIM: Arthrodesis of the proximal interphalangeal joint of the finger is a common procedure for the treatment of osteoarthritis. The aim of this biomechanical study was to compare the primary stability of one, respectively, two compression wires to intraosseous wiring and tension band wiring for the arthrodesis. MATERIALS AND METHODS: The stability of the arthrodesis was tested by applying flexion (n = 11) and extension (n = 10) force with 10° bending. Arthrodesis was achieved by one, respectively, two crossed compression wires and intraosseous wiring. In a control group (n = 11) tension band wiring was tested to 10° flexion and extension as well. RESULTS: Mean values for flexion bending for intraosseous wiring were 10.94 N, for one compression wire 12.82 N, for tension band wiring 17.95 N, and for two crossed compression wires 20.42 N. Mean values for extension bending were 9.71 N for intraosseous wiring, 13.63 N for one compression wire, 21.43 N for tension band wiring and 22.56 N for two crossed compression wires. CONCLUSION: The primary stability of the compression wires was statistically significant superior to intraosseous wiring. In comparison to tension band wiring which showed an intermediate stability. The application of a compression wire could be considered for further clinical testing in the arthrodesis of interphalangeal joints.

RESUMEN

A 50-year-old woman with an 8-year history of diffuse systemic sclerosis, a form of scleroderma, was referred by her rheumatologist to physical therapy for decreased finger range of motion (ROM) and pain that adversely affected her dexterity and ability to perform activities of daily living. To determine whether joint mobilization would be appropriate for this patient, posterior-to-anterior and modified lateral radiographs of both hands were requested by the physical therapist. Images showed significant bone loss in the distal phalanges of both thumbs and in the left third and fourth digits, and calcinosis in the tips of both thumbs. Because metacarpophalangeal and interphalangeal joint spaces appeared normal, except for a slight narrowing of the right fifth distal interphalangeal joint, joint mobilization, which would have been contraindicated by bone or joint destruction, was considered appropriate to help increase ROM.

RESUMEN

INTRODUCTION: Replacement of the metacarpo-phalangeal joints (MCPJ) with silastic Swanson's implants can help decrease pain, stiffness and allow for improved function in rheumatoid arthritis (RA). There is a lack of patient reported outcome measure (PROM) studies assessing the efficacy of this procedure in RA. The aim of this study was to report any change in function, pain, stiffness and satisfaction following the Swanson MCPJ replacement using patient reported outcomes in a rheumatoid population. METHODS: The combined results of 64 RA patients (71 hands) with 284 Swanson MCPJ arthroplasties (mean follow-up: 75.85 months) were assessed using the validated M-SACRAH questionnaire and a separate satisfaction questionnaire. Radiographic evaluation was performed to insure correct alignment of the hinged prosthesis postoperatively. No attempt was made to identify other predictors, radiologically or clinically. Data analysed in the study was interpreted in the context of the number of hands and survivorship was defined as implant fracture, loosening or revision. RESULTS: The mean total functional outcome score improved by 46.2% and the total pain outcome improved by 60.2%. The total stiffness outcome improved by 56.9% postoperatively and the results obtained from the satisfaction questions revealed that 73.2% of patients would retrospectively elect to have the procedure again. We report two postoperative complications in this group of superficial wound infections. Radiographically, all MCPJs showed improved alignment, however five patients reported worsening pain, four patients reported increased stiffness and four reported reduced function postoperatively. There was one re-operation of a 5th MCPJ Swanson's, which did not require implant exchange and one implant was revised. Implant survivorship was 98.6%. CONCLUSIONS: Patient satisfaction and functional surrogate markers were overall favourable. Our results support the continued use of Swanson silastic arthoplasty in advanced RA.

RESUMEN

Objectives. We evaluated the results of digital lengthening by distraction and second-stage bone graft. Methods. We treated finger deficiency of 201 digits in 104 patients (68 males, 36 females) by digital distraction and second-stage bone graft. The distraction was performed with a rate of 1 mm/day (for the first ten days) and 0.5 mm/day followed by using a self-designed bilateral tubal-helical external fixator. The mean follow-up period was 42 months (range 6 to 60 months). Results. The mean lengthening was 29.2 mm (range 25 to 40 mm) and 18.7 mm (range 12 to 32 mm) for metacarpal bones and phalanges, respectively. The mean elongation rate was 174.4% (range 145% to 202%) and 184.8% (range 115% to 283%) for metacarpal bones and phalanges, respectively. The static two-point discriminations and SpO2 showed no significant differences before and after distraction. Four complications were observed (two skin ruptures and two phalangeal splitting). No pin tract infection or tendon rupture showed. Digital lengthening improved functions of the hand. Conclusion. Digital distraction and second-stage bone graft is an effective method to compensate disabilities caused by lack of finger length. It could be an alternative plan for patients with thumb deficiency instead of toe-to-thumb transplant and patients with finger deficiency instead of ray resection.

RESUMEN

CONTEXT: Various predictors have been used to predict diabetic patients who are likely to have increased ventilatory hours and an increased length of stay (LOS) in the Intensive Care Unit (ICU) as well as in the hospital after undergoing coronary artery bypass grafting (CABG) surgery, for example, glycosylated hemoglobin (HbA1c). The authors propose a simple bed-side test, i.e., the prayer sign to predict increased ventilatory hours and increased length of ICU and hospital stay. AIMS: The aim of the present study was to assess whether any association exists between a positive prayer sign and increased ventilatory hours, length of ICU and hospital stay after CABG surgery in diabetic patients. SETTINGS AND DESIGN: This prospective observational study was conducted in a 650-bedded tertiary cardiac center. SUBJECTS AND METHODS: A total of 501 diabetic patients were recruited in the study over a period of 1 year. Group P consisted of 121 patients with prayer sign positive, whereas Group N consisted of 380 patients with prayer sign negative. HbA1c levels, ventilatory hours, LOS in the postoperative ICU and hospital were compared. STATISTICAL ANALYSIS USED: Unpaired Student's t-test was used to compare the data. RESULTS: The mean HbA1c levels in Group P were 8.01 ± 2.28% as compared to 6.52 ± 2.46% in Group N (P < 0.0001). The mean ventilatory hours in Group P were 9.52 ± 6.46 h, and in Group N were 7.42 ± 8.01 h (P = 0.013). Whereas, the mean length of ICU stay and hospital stay in Group P was 156.42 ± 32.66 h (6.51 ± 1.36 days) and 197.36 ± 32.46 h (8.22 ± 1.35 days), respectively, it was 121.12 ± 29.48 h (5.04 ± 1.22 days) and 178.52 ± 28.52 h (7.43 ± 1.18 days) in Group N (P < 0.0001). CONCLUSIONS: A positive prayer sign is a useful bedside test for predicting increased ventilatory hours and increased length of ICU and hospital stay after CABG surgery.

RESUMEN

Background: Closed reduction with percutaneous Kirschner wires (K-wires) is the most minimally invasive surgical option for stabilizing phalanx fractures. This study examines the effect of K-wire placement on proximal interphalangeal (PIP) joint motion. Methods: PIP joint flexion was measured in the digits of 4 fresh-frozen cadaver hands after placing a suture loop through the flexor tendons and placing tension on the flexors via a mechanical scale. The load necessary to flex the PIP joint to 90° or to maximum flexion was recorded. The load was removed and K-wires were inserted in 3 locations about the metacarpophalangeal joint (MPJ): through the extensor tendon and across the MPJ, adjacent to the extensor tendon insertion site and across the MPJ, and through the sagittal band and into the base of the proximal phalanx (P1). The load on the tendons was reapplied, and angles of PIP joint flexion were recorded for each of the 3 conditions. Results: The mean angle of PIP joint flexion prior to K-wire insertion was 87°, and the mean load applied was 241 g. The angles of flexion were 53° when the K-wire was placed through the extensor tendon, 70° when the K-wire was placed adjacent to the tendon, and 75° when the K-wire was placed into the base of P1 by going through the sagittal band, midway between the volar plate and the extensor tendon. Conclusions: K-wires placed remote from the extensor tendon create less of an immediate tether to PIP joint flexion than those placed through or adjacent to the extensor tendon.

RESUMEN

PURPOSE: To test the effectiveness of static and dynamic orthoses using them as an exclusive treatment for proximal interphalangeal (PIP) joint flexion contracture compared with other hand therapy conservative treatments described in the literature. METHODS: 60 patients who used orthoses were compared with a control group that received other hand therapy treatments. Clinical assessments were measured before the experiment and 3 months after and included active PIP joint extension and function. RESULTS: A significant improvement in the extension active range of motion at the PIP joint in the second measurement was found in both groups, but it was significantly greater in the experimental group. Improvement in function (Disabilities of the Arm, Shoulder, and Hand score) between the first and second assessment was similar in the control and experimental groups. CONCLUSIONS: Using night progressive static and daily dynamic orthoses as an exclusive treatment during the proliferative phase led to significant improvements in the PIP joint active extension, but the improvement did not correlate with increased function as perceived by the patient. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic I.

RESUMEN

Patients with bisphosphonate-related osteonecrosis of the jaws (BRONJ) who received intravenous or oral bisphosphonates (BP) were selected for determination of their bone microarchitecture as a risk predictor of BRONJ development. The diagnosis of BRONJ was made based on clinical and radiographic findings. The control group consisted of healthy patients. All patients underwent quantitative and qualitative ultrasound measurements of bone at the hand phalanges carried out using the DBM Sonic BP. Ultrasound bone profile index (UBPI), amplitude-dependent speed of sound (AD-SoS), bone biophysics profile (BBP), and bone transmission time (BTT) were measured. The BRONJ group consisted of 17 patients (62 ± 4.24; range: 45-82); 10 (58.8%) were male and seven (41.1%) were female, of whom 11 (64.7%) suffered from multiple myeloma, three (17.6%) from osteoporosis, one (5.8%) from prostate cancer, one (5.8%) from kidney cancer, and one (5.8%) from leukemia. Fourteen (82.3%) of them received intravenous BP whereas three (17.6%) received oral BP. Nine (9/17; 52.9%) patients developed bone exposure: two in the maxilla and seven in the mandible. Regarding quantitative parameters, Ad-SoS was low in the BRONJ group, but not significant. The UBPI score was significantly reduced in BRONJ patients with exposed bone when compared to controls (0.47 ± 0.12 vs. 0.70 ± 0.15; p = 0.004). The present study demonstrated that quantitative ultrasound was able to show bone microarchitecture alterations in BRONJ patients, and suggests that these analyses may be an important tool for early detection of bone degeneration associated with BRONJ.

RESUMEN

UNLABELLED: Computed digital absorptiometry is a low-cost and low-radiation technique for rapid measurement of phalangeal bone mineral mass. We implement and evaluate this technique on a slot-scanning radiography system. Results, based on measurements of excised phalangeal bones, indicate that the technique has potential for use in clinical assessment of osteoporosis. INTRODUCTION: The current gold standard method for bone assessment in the diagnosis of osteoporosis requires specialised and expensive machines, highly trained personnel to conduct the examination and is available only at specialist centres. The technique, termed dual-energy X-ray absorptiometry (DXA), involves taking a bone mineral density measurement at the femur or lumbar spine. Measurements of bone at peripheral sites such as the phalanges using DXA and other techniques have been shown to have potential use in the diagnosis of osteoporosis. Computed digital absorptiometry (CDA) is a low-cost, low-radiation radiographic technique for assessing phalangeal bone mineral mass. It uses an aluminium step wedge as a calibration device to compute bone mineral mass in units of equivalent aluminium thickness. In this study, we assess the feasibility of using CDA on a slot-scanning radiography system for measuring phalangeal bone mineral mass. METHODS: We implement and evaluate fully automated computed digital absorptiometry (CDA) of the middle phalanx of the middle finger on a slot-scanning radiography system. RESULTS: The ash weight of incinerated bones was measured and shown to have a correlation of 0.92 with CDA-derived bone mineral mass. CDA measurements had a coefficient of variation of 0.26%, indicating high precision. CONCLUSION: We conclude, based on these results, that CDA on a slot-scanning radiography machine may be useful for clinical assessment of osteoporosis.

RESUMEN

BACKGROUND: The aim of this study was to investigate retrospectively if soft tissue injuries have an impact on the functional results of surgically treated intra-articular fractures of the base of the middle phalanx. PATIENTS AND METHODS: From 1/2007 to 4/2010 we operated on 27 patients with intra-articular fractures of the base of the middle phalanx with pins, screws or external fixation analogous to Suzuki. 5 patients were excluded. 13 patients had no significant soft tissue injury (kWTV group), 9 patients had significant soft tissue damage including open fractures, skin lesions or/and severe soft tissue swelling (WTV group). Postoperative function and complications were analysed based on total active range of motion (TAM) and range of motion of the proximal interphalangeal joint (PIP-ROM) with regard to the Larsen score and clinical data. RESULTS: Fractures with soft tissue injuries had a significantly worse TAM outcome (p=0.04) than fractures without soft tissue injury (kWTV group: TAM 197.1°; WTV group TAM 231.2°) even if the functional results regarding the Larsen classification were excellent or good in both groups (kWTV 100%, WTV 88.9%). There were no significant differences regarding PIP-ROM of both groups. CONCLUSION: Soft tissue injuries have a negative impact on the functional results of surgical treated intra-articular fractures of the base of the middle phalanx. The influence on PIP-ROM might be less. Other factors might play a considerable role for PIP-ROM. With an adequate operative treatment most intra-articular middle phalanx fractures show good to excellent functional -results.

RESUMEN

This study estimated the prevalence of bone pathologies in a cohort of HIV-infected women in comparison with a cohort of HIV-negative women. Bone mineral density was measured by phalangeal quantitative ultrasound (AD-SoS: amplitude- dependent speed of sound; UBPI: ultrasound bone profile index). Risk of fracture, expressed by UBPI, was considered for value <0.39. Comparisons between groups and multivariate analyses were carried out using an ANOVA model. Correlations were evaluated using the Pearson correlation coefficient. Osteopenia and osteoporosis were present in 34.4% and 2% of patients, respectively. UBPI was pathologic in 5.7%. In a multivariate linear regression model significant correlations were found between AD-SoS z-score, duration of HIV-infection and BMI value. We also compared our cohort with 499 HIV-negative women as a historical control group of healthy subjects. AdSoS (2100 versus 2070 m/s) and UBPI (0.89 versus 0.74) were lower in HIV-infected women (p<0.001). Significant differences were also found in T-score values (p = 0.0013). These data show a high prevalence of bone diseases in women with HIV infection, correlated with duration of HIV-infection and BMI values. This non-invasive technique opens up new interesting perspectives, suggesting a possible use for bone mass screening in HIV-infected women.

RESUMEN

INTRODUCTION: Mallet fractures are avulsions of the terminal extensor tendon from the base of the distal phalangeal bone with a bony fragment. Surgical treatment, which provides accurate anatomical reduction and rigid fixation, is recommended for mallet fractures with involvement of more than one third of the base of the distal phalangeal bone. Various surgical methods have been reported, but there is still no standard treatment modality. The purpose of this investigation was to assess the results of our modified tenodesis method for mallet fractures. MATERIALS AND METHODS: Using our method, the dorsal fracture fragment was reduced and fixed to the main part of the distal phalangeal bone by 2 stitches of "figure-of-eight" 4-0 Prolene sutures. We reviewed 12 consecutive patients with 13 mallet fractures treated with our modified tenodesis method between January 2009 and March 2012. This retrospective study was composed of 7 male and 5 female patients, with a mean age of 35.7 years (range, 25-56 years). All patients underwent surgical treatment and sequent 3-week finger splinting. Patient follow-up lasted 3 to 6 months, with a mean period of 5.2 months. RESULTS: The modified tenodesis method allowed accurate anatomical reconstruction of the injured extensor mechanism. Grading by Crawford criteria showed that the outcome was "excellent" in 8 of 13 digits and "good" in 5 of 13 digits. The follow-up hand x-rays also revealed congruent joint surfaces of distal interphalangeal joints with no evidence of joint space narrowing. No wound complications were encountered, and all the patients returned to normal activities without any disability. CONCLUSIONS: The modified tenodesis method is simple and effective to provide accurate anatomical reduction and fixation for treatment of type I mallet fractures. No device penetration of the small bony fragment or pinning through the distal interphalangeal joint is required, and the surgical complication rate is low. We recommend this treatment modality for all but chronic cases.

RESUMEN

LEARNING OBJECTIVES: After reading this article, the participant should be able to: 1. Describe the concept of early protected movement with Kirschner-wired finger fractures to the hand therapist. 2. Choose the most appropriate method of fracture fixation to achieve the goal of a full range of motion. 3. Describe the methods of treatment available for the most common fractures and dislocations of the hand. BACKGROUND: The main goal of treatment of hand and finger fractures and dislocations is to attain a full range of wrist and nonscissoring finger motion after the treatment is accomplished. This CME article consists of literature review, illustrations, movies, and an online CME examination to bring the participant recent available information on the topic. METHODS: The authors reviewed literature regarding the most current treatment strategies for common hand and finger fractures and dislocations. Films were created to illustrate operative and rehabilitation methods used to treat these problems. A series of multiple-choice questions, answers, discussions, and references were written and are provided online so that the participant can receive the full benefit of this review. RESULTS: Many treatment options are available, from buddy and Coban taping to closed reduction with immobilization; percutaneous pins or screws; and open reduction with pins, screws, or plates. Knowledge of all available options is important because all can be used to achieve the goal of treatment in the shortest time possible. The commonly used methods of treatment are reviewed and illustrated. CONCLUSIONS: Management of common hand and finger fractures and dislocations includes the need to focus on achieving a full range of motion after treatment. A balance of fracture reduction with minimal dissection and early protected movement will achieve the goal.

RESUMEN

Corrective osteotomies are often utilised to treat finger deformities that may occur due to a phalangeal malunion. Rotational or angular malalignment, in addition to shortening of the digit may negatively affect hand function and be aesthetically displeasing. Thorough preoperative examination of the malunion and its associated deformities is crucial in determining the type of osteotomy technique to be used. Osteotomies can create bony defects that need to be filled with bone graft or some type of graft substitute. We describe an opening wedge osteotomy with local cancellous bone graft combined with dual plating to treat a dorsal angular deformity in a proximal phalangeal malunion.
