RESUMO
BACKGROUND: Ulnar-sided wrist pain might be caused by a lesion of the triangular fibrocartilage complex (TFCC). Patients with TFCC lesion may show an instability of the distal radioulnar joint (DRUJ). Before arthroscopic assessment, conservative therapy using a brace or splint may result in alleviation of symptoms. The results of our previous study showed that patients with a traumatic TFCC lesion and instability of the DRUJ had the smallest weight-bearing capacity and had the largest increase in application of the wrist brace (WristWidget). PURPOSE: In this prospective study, we wanted to test if the weight-bearing capacity with and without the wrist brace can be used as a diagnostic tool to differentiate between patients with traumatic TFCC lesion and instability of the DRUJ. We tested if patients with traumatic TFCC lesion and instability of the DRUJ (1) have a lower weight-bearing capacity and (2) show a higher increase of weight-bearing capacity after application of a wrist brace compared to all other types of injury. STUDY DESIGN: This was a prospective cohort study. METHODS: Forty-eight patients presented to an outpatient clinic with suspected TFCC lesion. We measured the dynamic weight-bearing capacity of both hands with and without the wrist brace (WristWidget) by letting the patients lean on an analog scale with extended arm and wrist. The stability of the DRUJ was assessed by clinical examination by a hand surgeon preoperatively and intraoperatively. Forty-five patients received an arthroscopy and were included in the analysis. During arthroscopy, the surgeon determined if there was a traumatic TFCC lesion and DRUJ instability. Patients with a traumatic lesion of the TFCC and DRUJ instability were compared to all other cases. We used the t-test for normally distributed values, Mann-Whitney U test for nonnormally distributed values, and the Chi-square test for categorical variables, respectively Fisher's exact if the expected cell count was less than five. RESULTS: Patients with a traumatic TFCC lesion and DRUJ instability had a higher weight-bearing capacity (22.8 kg) than all other cases (13.8 kg; p < 0.01). This is in contrast to our previous study, in which patients with a traumatic lesion of the TFCC had the tendency to show lower values of weight-bearing capacity than those with a degenerative lesion. While the wrist brace was worn, the relative gain was not significantly lower in patients with traumatic TFCC lesions and DRUJ instability compared to all other cases (21% vs 54%, p = 0.16). All included cases showed the same absolute increase of about 4 kg in weight-bearing capacity with the wrist brace (p = 0.93) CONCLUSIONS: The weight-bearing test cannot be used to identify patients with traumatic TFCC lesion and DRUJ instability among those with suspected TFCC lesion. The results of our previous study could be confirmed that the weight-bearing capacity on the injured side was higher with brace than without.

BACKGROUND: American football is known for its high risk of injury, especially in the professional field. Although the number of players in the German football league (GFL) has risen in recent years, data concerning the injury rates of German amateur players in American football are scarce. OBJECTIVE: Analysis of the injury rates in league games and training sessions in amateur football according to playing positions and body region. MATERIAL AND METHODS: Injuries of 123 American football players in a club playing in the second GFL (first and second team) were prospectively recorded over a period of 4 seasons (2014-2018). A complete history of injuries was obtained from 72 players. The injuries were classified using the Orchard sports injury classification system 10.1 (OSICS 10.1). The injury rates were calculated per 1000 athlete exposures (AE) for training as well as for league games with respect to the playing position and for each body region. RESULTS: Overall 142 injuries were recorded. On average there were 35.5 injuries per season and 1.9 injuries per player. Of the injuries 54.7% occurred during training and 46.1% during games. The risk of injury was significantly increased during league games (15.6⯱ 16.3) compared to training (3.1⯱ 2.7, pâ¯< 0.0001). While wide receivers and cornerbacks had the highest overall injury rates, running backs had the highest injury risk during games (pâ¯= 0.046). Injuries to knees (27.3%) and shoulders (20.1%) were the most frequent. The shoulder was the body region injured most frequently during games (pâ¯= 0.002). Regarding the injury pattern, distorsions (30.9%) and contusions (22.5%) occurred more often compared to fractures (12.6%) and dislocations (16.1%). Concussion only contributed to 2.9% of the injuries. CONCLUSION: American football is a contact sport with high injury rates even in the German amateur field, especially during league games. Regarding body regions, shoulders and knees were predominantly affected while regarding the playing position, wide receivers and cornerbacks were particularly jeopardized. Therefore, a continuous close medical supervision during games and an intensive position-specific training seem to be necessary even in the amateur field in order to reduce the injury rate.

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.

INTRODUCTION: Ulnocarpal impaction syndrome is a common cause of chronic ulnar-sided wrist pain. The distal ulnar shortening osteotomy addresses the often present positive ulnar variance and therefore relieves the excessive load on the ulnocarpal joint. In the present study, the results of a technique that uses an ulnodorsal approach with a compression device and a transverse osteotomy are presented and compared to other techniques. MATERIALS AND METHODS: This retrospective study includes 92 wrists with an ulnocarpal impaction syndrome, which were treated with an ulnar shortening osteotomy. The mean duration of postoperative follow-up was 50 months. RESULTS: The mean ulnar variance was 2.17 ± 1.56 mm preoperatively and after the ulnar shortening osteotomy -1.36 ± 1.67 mm (p < 0.05). Radiological consolidation of the osteotomy could be shown in 91 wrists 6 months postoperatively. Patients rated the preoperative pain level at a VAS 7.9 ± 1.7 which decreased to a of VAS 2.4 ± 2.5 (p < 0.05). 19 patients complained of mechanical irritation. There was no neurological irritation. CONCLUSION: It could be shown that the distal ulnar shortening osteotomy by a transverse osteotomy using a compression device and an ulnodorsal approach has a low complication rate. It is comparable to the oblique osteotomy in effectiveness and safety.

PURPOSE: The wrist is involved early in rheumatoid arthritis and is often severely affected. A stable wrist is crucial to good hand function, which often necessitates a fusion. One of the most commonly used techniques in rheumatoid patients is the Mannerfelt arthrodesis. In this retrospective study the outcome and the patient's subjective satisfaction are presented and compared to other techniques. Also the influence of the position of the wrist following a fusion procedure is analysed. METHODS: Thirty-four wrists were retrospectively analysed using radiological measurements, functional scores such as the Disabilities of the Arm, Shoulder and Hand (DASH) and a pain assessment. The objective function of the hand with the fused wrist was assessed. RESULTS: In 92.6% of wrists the patients rated their satisfaction as good or excellent. The mean DASH score post-operatively was 63.3. Of the wrists, 17 were fixed in a median flexed position of 13° and 17 wrists in a median extended position of 8°. There was no statistically significant correlation between the position of the wrist and the satisfaction or objective function. The rate of fusion was 94.1%. CONCLUSIONS: The Mannerfelt arthrodesis achieves good results and provides a high rate of satisfaction and pain relief in our study. It has major advantages compared to other wrist fusion techniques in the rheumatoid patient. We could not show clear statistical evidence for better results in either a flexed or an extended position, but the ratings of the patients indicated better subjective results with a slightly extended position of the arthrodesis.

INTRODUCTION: The giant cell tumour of the tendon sheath (GCTTS) of the hand is a benign tumour of unknown origin. The clinical diagnosis is supported by preoperative imaging. But the ideal imaging methods necessary for the diagnosis, preoperative planning and total tumour resection are still debated. Standard treatment is surgical resection with histological confirmation. METHODS: We followed up 84 patients who were operated upon for a histologically confirmed nodular type GCTTS for an average of 4.7 years (range four to eight). The preoperative symptoms and radiological findings of X-ray, ultrasound and MRI were reviewed and the surgeon asked for their impact on the surgical procedure. RESULTS: The average age at operation was 50.9 years, 65.5% of the patients were female and 61.9% of the lesions were located on the palmar aspect. Most tumours were found on the first three fingers. Two patients had tumours at two separate sites (2.4%). After an average follow up of 31.5 months two recurrences were observed (2.4%). In addition to X-ray and ultrasound, the preoperative findings of the MRI had no influence on the surgical procedure. CONCLUSION: Our data on the nodular GCTTS are in accordance with published data concerning the age distribution, gender distribution, and localisation. No soft-tissue imaging method is superior for the diagnosis of nodular GCTTS or for the preoperative planning. A preoperative MRI may not be necessary as clinical and ultrasound examination are sufficient. To exclude bony erosions, a preoperative X-ray is necessary.

Background: Malnutrition might lead to a worse outcome in hip fractures of older patients. The purpose of this study is to analyze different indicators of malnutrition that lead to worse outcomes. Methods: 252 patients of a geriatric trauma unit were analyzed prospectively. Different demographic, as well as data on the trauma and whether osteoporosis prophylaxis or anticoagulation was present, were recorded. The nutritional status with respect to laboratory parameters as well as nutritional risk score was also analyzed. Results: The main finding of this study is that a poor nutritional status is statistically significantly associated with higher mortality as well as worse independence (p < 0.05). A postoperatively prescribed osteoporosis prophylaxis is protective of mortality and independence (p < 0.05). Conclusions: Malnutrition of geriatric patients increases the risk for death, worse mobility, and independence after hip fractures. Osteoporosis prophylaxis prescribed during an inpatient stay enables patients to retain their independence. The nutritional status of geriatric patients with hip fractures should be obtained and provisions made.
RESUMO
(1) Quadriceps tendon rupture (QTR) is a rare pathology, usually occurring in elderly patients with comorbidities, requiring surgical therapy. The aim of this study was to analyze rupture patterns and concomitant injuries using preoperative magnetic resonance imaging (MRI) and to evaluate patient-reported outcome measures. (2) In this retrospective cross-sectional study, 113 patients with QTR were screened and rupture patterns/concomitant injuries (n = 33) were analyzed via MRI. Clinical outcome was assessed in 45 patients using the International Knee Documentation (IKDC) and Lysholm score with a mean follow-up of 7.2 (±5.0) years. (3) The evaluation of preoperative MRIs showed multiple ruptures of subtendons in 67% with concomitant knee injuries in 45%. The most common associated pathology detected using MRI was pre-existing tendinosis (31.2%). Surgical refixation demonstrated good results with a mean post-operative IKDC score of 73.1 (±14.1) and mean Lysholm score of 84.2 (±16.1). Patient characteristics and individual radiologic rupture patterns did not significantly affect the clinical outcome of patients. (4) Acute QTRs are complex injuries with common involvement of multiple subtendons. MRI imaging can be useful for achieving an accurate diagnosis as pre-existing tendinosis as well as concomitant injuries are common, and might be useful for providing an individual surgical strategy and improving outcomes.
RESUMO
(1) Background: Patellar tendinopathy (PT) is an overuse condition of the knee extensor mechanism characterized by ventral knee pain at the lower pole of the patella and limited functionality. (2) Methods: In this retrospective study, a group of patients with PT (n = 41) was compared with a control group (n = 50) in terms of patient-related data and magnetic resonance imaging (MRI) characteristics. (3) Results: Patellar height was higher in the PT patient group and there was a significant difference in Caton-Deschamps index (CD) compared to the control group (p = 0.021). Patients with PT showed a lower patella-patellar tendon angle (PPTA) (p = 0.011). The patellar tendon thickness (PTT) in the proximal (PTTprox), middle (PTTmid) and distal (PTTdistal) part of the tendon was significantly thickened (p < 0.001). Increased signal intensity in MRI was detected in symptomatic tendons over 6 months compared to a duration of less than 6 months (p = 0.025). A significant relationship between the PTTprox and an increased signal intensity was observed (p < 0.001). (4) Conclusions: Patients with PT showed a significant difference in the patellar height and PPTA. With persistence of symptoms over 6 months, MRI seems suitable to detect the morphologic tendon changes and further identify patients suitable for surgical procedures.
RESUMO
BACKGROUND: Proximal humeral fractures (PHFs) are common injuries that can lead to significant functional impairment. This retrospective cohort study aimed to evaluate the clinical outcomes and complications associated with the use of the Targon PH+ (Fa. Aesculap, Germany) intramedullary nail for the treatment of PHFs. METHODS: A subgroup consisting of 70 patients with a mean follow-up of 4.91 years out of 479 patients who underwent treatment with the Targon PH+ intramedullary nail for PHFs at a single center between 2014 and 2021 were included. Patient-reported outcome measures (PROMs) and health-related quality of life (HRQoL) were assessed using validated German versions of the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, American Shoulder and Elbow Surgeons (ASES) score, Oxford Shoulder Score (OSS), and EuroQol 5-Dimension 5-Level (EQ-5D-5L). Radiographic assessment was performed using pre- and postoperative imaging. RESULTS: Among the 70 patients of the subgroup who completed follow-up, 21.4% experienced complications, including major complications in 15.7% of cases, all of which were revised (revision rate of 15.7%). Anatomical reduction was achieved in 48,5% of cases. The mean DASH, ASES, and OSS scores were 25.4 ± 22.0, 76.2 ± 21.1, and 38.8 ± 10.3, respectively. Significant correlations were observed among the PROMs, indicating their convergent validity. Additionally, a significant correlation of all used PROMs and patient well-being (HRQoL) was observed. Severe complications and revisions were associated with significantly lower ASES scores (-11.1%, p = 0.013). There was a tendency for PROM scores to slightly decline with increasing fracture complexity, although this trend did not reach statistical significance. Our findings indicate that patients over the age of 65 years tend to exhibit lower scores in PROMs and HRQoL measures. CONCLUSION: The use of the Targon PH+ intramedullary nail for the treatment of PHFs resulted in satisfactory clinical outcomes and acceptable complication and revision rates. The PROMs and HRQoL measures indicated varying levels of disability and symptoms, with major complications, revision surgery, and age negatively impacting shoulder function after midterm follow-up.
RESUMO
BACKGROUND: Hip fractures in geriatric patients often have a poor outcome in terms of mortality, mobility as well as independence. Different surgical influence factors are known that improve the outcome. METHODS: In this observational cohort study, 281 patients of a geriatric trauma unit were analyzed prospectively. Demographic factors, as well as data regarding the trauma mechanism and perioperative treatment, were recorded. The nutritional status was also analyzed. The follow-up was set to 120 days. RESULTS: The key conclusion of this study is that a high ASA classification, the use of anticoagulatory medicine and malnutrition are significantly associated with higher mortality together with worse independence (p < 0.05). There is no significant difference in outcome concerning the time to surgery within the first 24 h. CONCLUSIONS: Malnutrition seems to be an important risk factor for an adverse outcome of geriatric patients and therefore warrants a focus in multidisciplinary treatment. The risk factor ASA cannot be improved during the pre-surgery phase, but requires intensified care by a multidisciplinary team specialized in orthogeriatrics.
RESUMO
Septic arthritis of the shoulder is an urgent medical emergency that often occurs in elderly patients and is associated with high morbidity and mortality. Retrospectively, 56 patients aged ≥60 years, treated for primary septic monoarthritis of the shoulder at a maximum care hospital between 1 July 2001, and 30 July 2022, were included in this study. The primary aim of the study was analyzing survival rates and different bacteria in these patients. For statistical analysis, Kaplan-Meier curves were used for survival probability and the log-rank test was used to compare a survival probability of 5 years. The mean patient age was 78.7 years and a mean follow-up time of 3011.8 days. The mean survival of the entire study population was 920.3 days or 2.5 years. Significantly impaired 5-year survival was found only with increasing age and higher American Society of Anesthesiologists (ASA) physical status (PS) classification scores. Eight different types of bacteria were detected in the synovial fluid cultures. A total of 42 of 48 overall pathogens was Gram-positive and 6 were Gram-negative bacteria. Staphylococcus aureus was identified as the most frequent variant. We conclude that the mean survival is significantly shortened within the first 5 years with increasing age and ASA PS classification.
RESUMO
BACKGROUND: Osteoarthritis of the proximal interphalangeal (PIP) joint of the finger often leads to global hand-function detriment. Different techniques for the arthrodesis of the proximal interphalangeal joint have been described that all lead to union in a reasonable percentage of patients and period of time. This biomechanical study aims to analyze and compare the primary stability of different techniques of arthrodesis to render postoperative immobilization unnecessary. METHODS: Arthrodeses of 40° of composite cylinders were tested with different techniques in four-point bending for stability in extension as well as flexion. RESULTS: In extension, the compression screw and the compression wires showed the highest stability-whereas in flexion, plate fusion was superior. Tension band, cerclage or compression screw fusion showed the best compromise in flexion/extension stability. CONCLUSIONS: Fusion techniques that apply compression to the fusion show superior stability. Cerclage, tension band and compression screws might be able to provide enough stability to withstand the forces exerted during unencumbered activities of daily living. Arthrodesis with plates should be limited to patients with special indications and require immobilization during consolidation.
RESUMO
Overboarding politcal influence in Germany concerning medical issues has come to a new peak. The report by the IGES Institute published in 2022 made an important contribution in this regard. Unfortunately, only that part of the recommendations of this report were implemented in a new version of the contract for outpatient surgery according to Section 115b SGB V (AOP contract), that called for an expansion of outpatient surgery. In particular, those aspects that are important from a medical point of view for a patient-specific adjustment of outpatient surgery (e. g. old age, frailty, comorbidities) as well as the important structural requirements for outpatient postoperative care were included in the new AOP contract at best in a rudimentary manner. For this reason, the German Society for Hand Surgery felt compelled to give its members a recommendation as to which medical aspects must be taken into account, especially when performing hand surgery operations, in order to ensure the highest level of safety for the patients entrusted to us while performing outpatient surgery. An expert group of experienced hand surgeons and hand therapists who work in hospitals of all levels of care as well as resident surgeons was formed in order to formulate mutually agreed recommendations for action.

Knee injuries are one of the most common injuries. Falls during the immobilization period can deteriorate the postoperative outcome. The risk factors causing falls after initial injury and the question of whether a rigid orthosis serves as a protective factor remain unclear. The primary aim of the study was to record the fall rate in the first six weeks after arthroscopic intervention. The secondary aim was to assess the influences of risk factors and protective factors on these fall ratios. Different scores were examined and compared in the groups 'fall event' and 'no fall'. Data from 51 patients (39 males, 12 females) with a mean age of 31.2 years (19-57 years) were collected. A total of 20 patients suffered at least one fall event within the observation period. A total of 18 of 23 fall events happened within the first three weeks postoperatively. The Extra Short Musculoskeletal Function Assessment Questionnaire (XSMFA) showed a significant difference between the groups (p = 0.02). People with multiple injuries to the knee joint were more likely to suffer fall events. Conclusively, patients with limited knee functions appeared to fall more frequently within the first three weeks postoperatively. Therefore, appropriate measures should be taken to protect the postoperative outcome. Physical therapy and patient behavioural training should be practiced perioperatively in patients at risk.
RESUMO
Arthrodesis of the proximal interphalangeal (PIP) joint of the finger is an established procedure for advanced osteoarthritis. As there are different techniques of fusion, it seems necessary to evaluate the results. Primary outcome of this review was to evaluate different arthrodesis methods of the PIP joint and describe different numbers of non-unions. Secondary outcome was to evaluate time to consolidation. Respective complications, if mentioned, were listed additionally. The review process was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The selected databases were PubMed, Medline, Embase, Google Scholar and Cochrane Library. Studies reporting outcomes of the arthrodesis with a defined technique and radiological consolidation were included. Complication rates and types were recorded. In total, 6162 articles could be identified, 159 full-texts were assessed and 64 studies were included. Methodological quality was assessed using Methodological Index for Non-Randomized Studies. A total of 1923 arthrodeses of the PIP joint could be identified. Twelve different surgical techniques were described, four of these techniques with compression at the arthrodesis site. The most frequently used techniques were K-wires (n = 743, 14 studies), tension-band (n = 313, 15 studies) and compression screws (n = 233, 12 studies). The lowest rate of described non-unions in compression techniques was 3.9% with the compression screw. The highest non-union rate of 8.6% was achieved by interosseous wiring. All the described techniques can achieve the goal of fusing an osteoarthritic joint. There is a tendency in the more recent literature for the use of compression techniques.
RESUMO
Background: Operative management of proximal humeral fractures is still challenging. While antegrade nailing has become a valid option in fracture fixation, risk factors for adverse events, and failure have not been sufficiently clarified. Methods: All patients of a single trauma center undergoing surgery for proximal humeral fractures with the Targon PH+ nail between 2014 and 2021 were evaluated retrospectively. This included complications, revisions, and failures. Pre- and postoperative radiographic imaging were assessed regarding fracture's complexity, anatomic reduction, reconstruction of the medial hinge, metaphyseal head extension, and fixation of the implant in the calcar region. Follow-up was at a minimum of 12 months. Results: A total number of 130 patients with a mean age of 74.5 years (range 63−94, SD ± 8.2) are included in this study. Two- and three-part fractures were found in 58 patients, while 14 patients showed four-part fractures. Overall, a complication rate of 34.2% and an implant failure rate of 15.4% was found. Four-part fractures showed a significantly higher complication rate than two- and three-part fractures. Four-part fractures also showed significantly higher revisions (p = 0.005) and implant failures (p = 0.008). The nonsufficient anatomical reduction was found to be a risk factor for complications (p < 0.0001), implant failures (p < 0.0001), and later humeral head osteonecrosis (p < 0.0001). Insufficiently reconstructed medial hinges (p = 0.002) and a metaphyseal head extension of under 8 mm (p = 0.005) were also demonstrated as risk factors for osteonecrosis of the humeral head. Conclusions: Four-part fractures in an elderly population show high complication, revision, and implant-failure rates. Therefore, demonstrated radiologic risk factors should be evaluated for improvements. Anatomical reduction and fixation near the calcar proved to be vital for successful antegrade nailing of complex fractures. To prevent osteonecrosis of the humeral head, reconstruction of the medial hinge and metaphyseal head extension should be evaluated.
RESUMO
Septic arthritis is common in older adults and can be related to joint surgery or hematogenous distribution. To date, the risk factors affecting survival are unknown. This study aimed to evaluate the effects of existing implants, positive synovial microbiological culture results, and the American Society of Anesthesiology Physical Status (ASA) classification on the short- and mid-term survival of older patients with primary septic gonarthritis. This retrospective study included 133 older adults >60 years who underwent surgery for primary septic gonarthritis. Data were collected from medical records and public obituaries. Kaplan-Meier survival curves were used to estimate the probability of survival, as well as log-rank tests to measure and compare survival rates over one- and five-year periods. The mean age was 74.9 years (SD ± 9.2), and the 5-year follow-up rate was 74.3% (the mean follow-up was 3000.5 days; SD ± 1771.6). Mean survival was significantly different in patients with implants and without implants (p = 0.015), and between ASA II, ASA III, and ASA IV (p < 0.001). There was no significant difference in the survival of patients with or without a positive synovial microbiological culture (p = 0.08). Older adults with septic monoarthritis and pre-existing medical implants showed impaired survival. The ASA classification prior to surgery for primary septic monoarthritis can be helpful in identifying patients with poorer mid-term outcomes.
RESUMO
Osteomyelitis of the hand and wrist is uncommon compared to the infections of the long bones but not rare. There is poor evidence on many answers to questions concerning this disease. This includes careful consideration of the prevalence, pathogenesis, microbiology, diagnostic methods and the conservative, medical and surgical treatment. The emergence of the disease can subdivided in post-traumatic, postoperative, spread from contiguous infections and hematogenous. The individual patient-specific risk must be considered. Early diagnosis and correct management are essential to preserve bony structures and the articular function of the hand. A two-step surgical procedure is usually necessary, but uncertainties about the optimal treatment are still existing. Satisfactory control rates of the infection and successful bone reconstructions can be achieved. But complications, a limited range of motion and amputations of finger parts can still not be avoided in all cases.
