[Geriatric Proximal Femoral Fracture and Urinary Tract Infection - Considerations for Perioperative Infection Prophylaxis]. / Geriatrische proximale Femurfraktur und Harnwegsinfekt ­ Überlegungen zur perioperativen Infektionsprophylaxe.

Background: Perioperative infection prophylaxis with cephalosporins is standard in surgical treatment of proximal femoral fractures (PFF). Geriatric patients (pat.) are at risk of chronic infections and the bacteria from these can lead to unknown hygienic problems in an early operation. We therefore characterised the colonisation of the urinary tract in pat. (≥ 65 years) with PFF and observed bacterial development in deep wound infections over a period of 10 years. The aim was to discover gaps in perioperative infection prophylaxis. Patients and Methods: Between September 2013 and November 2015, colonisation of the urinary tract and microbial resistance were investigated on admission of all pat. (≥ 65 years) with the diagnosis of PFF (n = 351; f/m 263/88; median age [∅] 83.57 [65-100] years). Between 2005 and 2014, 2161 pat. with a PFF were operated in our clinic (f/m 1623/538; ∅ 82.35 [65-101] years). 991 pat. (∅ 81.84 [65-101] years) with femoral neck fracture [FNF] were treated with endoprosthesis/osteosynthesis, 1170 pat. (∅ 82,78 [65-101] years) with per-/subtrochanteric fracture [PTF] were treated with osteosynthesis. In a retrospective data analysis, deep wound infections, microbiological composition and changes in microbial resistances over time were identified. Results: Bacteriuria (BU) was detected in the urine sediment of 35.61 % (n = 125) of our pat. In 47.2 % of these pat., BU was accompanied by laboratory signs of manifest urinary tract infection. In 10.4 % of these pat., colonisation of the urinary tract with multi-resistant pathogens was detected; 26.4 % were resistant to cefuroxime. The rate of deep infections in pat. with endoprosthesis/osteosynthesis in FNF was 2.8 % (n = 28; f/m 19/9; ∅ 81.35 [67-92] years), with osteosynthesis in PTF 1,1 % (n = 14; f/m 10/4; ∅ 81.0 [70-91] years). A comparison of the periods 2005-2009 and 2010-2014 showed a shift in the spectrum of pathogens from cephalosporin-sensitive to cephalosporin-resistant enterococci. Resistance of pathogens against cephalosporins increased from 43 to 81 %. Conclusion: We found an increasing risk in geriatric pat. from multiresistant pathogens in the urinary tract and from an increase in the cephalosporin resistance of pathogens in urinary tract infections and in deep wound infections. This indicates that perioperative infection prophylaxis with a cephalosporin is not effective. Especially in nursing homes, development of resistance to antibiotics is an increasing problem. Thus, concepts of perioperative infection prophylaxis in geriatric patients should be reconsidered.

[Intramedullary Stabilisation of Displaced Midshaft Clavicular Fractures in Heavy Workers and Complex Fracture Pattern]. / Intramedulläre Stabilisation von dislozierten Klavikulaschaftfrakturen bei Schwerarbeitern und komplexen Frakturen.

BACKGROUND: The medical literature recommends plate osteosynthesis (PO) for complex displaced midshaft clavicular fractures (DMCF) OTA type 15B3 and for heavy workers with displaced clavicular fractures. Recovery of DMCF treated with intramedullary stabilisation (IMS) will be examined and compared to published data for duration of inability to work (DIW) after conservative treatment as well as after PO, with respect to the DIW. PATIENTS AND METHODS: Between 09/2009 and 07/2015, the DIW of 58 patients (8 f, 50 m, mean age 38.4 [20-59] years) with DMCF treated with open reduction and IMS (Titanium Elastic Nail [TEN], Synthes, Umkirch, Germany) was determined. Inclusion criteria were the presence of closed unilateral DMCF and presence of a job with national insurance at the time of accident. DIW was counted in days, starting with the accident, and ending on the last day before resumption of full work. All patients were functionally treated for 6 weeks postoperatively without weights for the shoulder and with a maximum of 90° abduction/flexion. The workload was classified in accordance with REFA criteria: group 0-1 (low physical workload) and group 2-4 (high physical workload). Fracture patterns (simple vs. complex) and postoperative physiotherapy (yes vs. no) were investigated for both REFA groups, as these factors may influence DIW. Fracture classification was performed in accordance with the OTA classification, as simple fractures (OTA type 15B1 and 15B2), and complex fractures (OTA type 15B3). Effects were concerned significant if p ≤ 0.05. RESULTS: Median DIW was independent of physical workload, with 39.86 (3-150) days (n = 58). Patients with low physical workload (REFA 0-1; n = 33) had shorter duration of DIW, with an average of 32.48 (3-136) days than patients with higher physical workload (REFA 2-4; n = 25), with 49.6 (14-150) days (p = 0.02). The fracture type did not influence this significantly (simple fractures [n = 35]: average 40.54 [3-150] days; complex fractures [n = 23]: average 38.82 [14-136] days, p = 0.85). Within each REFA group, differences in DIW for each fracture type were greater, but did not attain statistical significance. Patients without postoperative PT (n = 30) had a shorter DIW, with an average of 30.5 (3-84) days, than patients with postoperative PT (n = 28), with an average of 49.89 (14-150) days (p = 0.021). Within both REFA groups, DIW changed similarly with postoperative PT, in some cases with statistical significance. CONCLUSION: DIW after IMS of DMCF does not depend on the complexity of the fracture. For heavy workers, DIW after IMS is significantly longer than for light physical workers. IMS of DMCF permits immediate pain-adapted movement of the shoulder, with a maximal abduction/flexion up to 90°, no matter what the fracture type. Patients given additional professional PT showed longer DIW than those without such treatment.

[A Problematic Case: Removal of a Broken Cannulated Tibial Nail]. / Problemfall: Entfernung eines gebrochenen kanülierten Tibiamarknagels.

We present a case illustrating a simple and safe technique for the removal of a broken cannulated tibial nail after a pseudarthrosis of a lower leg shaft fracture. A 3 mm Ball-Tip guide wire was inserted into the proximal and the distal segment of the nail. A 2.5 mm tip-flattened second wire was forwarded into the distal segment pushing the Ball-Tip guide wire out of the axis and blocking it. This way the Ball-Tip could act as a hook and consecutively could be knocked back with an impactor forceps removing the complete nail. An exchange nailing was performed with a reamed AO standard nail and the further course was uneventful with a healed fracture after 12 months.

[Intramedullary stabilisation of displaced midshaft clavicular fractures: does the fracture pattern (simple vs. complex) influence the anatomic and functional result]. / Intramedulläre Stabilisation von dislozierten Klavikulaschaftfrakturen - Hat die Frakturform (einfach vs. komplex) Einfluss auf das anatomische und funktionelle Ergebnis?

BACKGROUND: Displaced midshaft clavicular fractures are often treated operatively. The most common way of treatment is plating. Elastic stable intramedullary nailing (ESIN) is an alternative, but seldom used. Studies showed comparable or even better results for intramedullary nailing than for plating in simple 2- or 3-fragment midshaft fractures. The indication of ESIN for multifragmentary clavicular fractures is discussed critically in the literature because of reduced primary stability and danger of secondary shortening. Until now only few studies report functional results after fracture healing depending on the fracture type. To the best of our knowledge there is no study showing significantly worse functional scores for ESIN in complex displaced midshaft fractures. The objective of this study was to examine anatomic and functional results of simple (2 or 3 fragments, OTA type 15B1 and 15B2) and complex (multifragmentary, OTA type 15B3) displaced midshaft clavicula fractures after internal fixation. PATIENTS AND METHODS: Between 2009 and 2012, 40 patients (female/male 10/30; mean age 33 [16-60] years) with closed displaced midshaft clavicular fractures were treated by open reduction and ESIN (Titanium Elastic Nail [TEN], Synthes, Umkirch, Germany). Thirty-seven patients were retrospectively analysed after a mean of 27 (12-43) months. Twenty patients (group A) had simple fractures (OTA type 15B1 and 15B2), 17 patients (group B) had complex fractures (OTA type 15B3). All shoulder joints were postoperatively treated functionally for six weeks without weight limited to 90° abduction/flexion. Both groups were comparable in gender, age, body mass index, months until metal removal, number of physiotherapy sessions and time until follow-up examination. Joint function (neutral zero method) and strength (standing patient with arm in 90° abduction, holding 1-12 kg for 5 sec) in both shoulders were documented. The distance between the centre of the jugulum and the lateral acromial border was measured for both sides. The DASH, Constant-Murley, Oxford shoulder and clavicular scores (Jubel) were calculated. Patients documented contentedness of outcome by VAS between 0 (absolute discontented) and 10 (very contented). Complications were recorded. RESULTS: Operatively treated displaced midshaft clavicular fractures. in comparison to the healthy side in group A had an average shortening of 5 (0-20) mm and in group B of 10 (3-25) mm, with a statistical significance between both groups. Patients of both groups were very contented with the results (VAS group A: 9.6; B: 9.5). DASH score (group A: 28; B: 3.1), Constant-Murley score (group A: 95.0; B: 93.8), Oxford shoulder score (group A: 46.2; B: 45.9) and the clavicula score (Jubel) (group A: 1.2; B: 2.1) were comparable between both groups without significance. In 4 patients (11%) complications occurred. Once (group B) an infection was seen, three times (group B) the ESIN had to be shortened on the medial side because of telescoping. CONCLUSION: Open ESIN of simple and complex displaced midshaft clavicular fractures leads after an average of 27 months to good or even excellent results. Healing of the clavicle in a modestly shortened position does not impair the patient.

Trapeziectomy and ligament reconstruction tendon interposition for isolated scaphotrapeziotrapezoid osteoarthritis of the wrist.

Isolated osteoarthritis of the scaphotrapeziotrapezoid joint is rather rare compared with thumb trapeziometacarpal osteoarthritis. The aim of this retrospective study was to evaluate the outcome of 15 consecutive patients treated with trapeziectomy/ligament reconstruction tendon interposition for isolated scaphotrapeziotrapezoid osteoarthritis of the wrist. After a mean follow-up of 54 months, 14 patients (15 wrists) were available for clinical and radiological examination. The median pain intensity was 0 on a 0-10 visual analogue scale, both at rest and with activity, mean grip strength averaged 24 kg, pinch strength 5 kg. The disabilities of the arm, shoulder and hand (DASH) score was 16, and a modified Mayo Wrist Score 84. Correlation between the degree of scaphotrapezoid osteoarthritis and pain at rest, pain with activity, and DASH score was not significant. The findings from our study suggest that trapeziectomy/ligament reconstruction tendon interposition is an effective procedure for treating isolated scaphotrapeziotrapezoid osteoarthritis, and that additional partial trapezoid excision is not necessary.

[Simultaneous bilateral humeral head disclocation and acetabular fracture. A rare manifestation after hypoglycemia-induced seizures]. / Simultane beidseitige Humeruskopfluxations- und Acetabulumfraktur. Eine seltene Folge eines hypoglykämieinduzierten Krampfanfalls.

Seizures can cause severe musculoskeletal injuries and posterior shoulder dislocation is a typical result of a seizure. Bilateral posterior shoulder dislocation is rare and acetabular fractures caused by a seizure are also a rarity. We present the case of a 48-year-old man with simultaneous bilateral posterior shoulder fracture dislocations and bilateral acetabular fractures as a result of hypoglycemia-induced seizures.

[Patients with periprosthetic femur fractures and consecutive stem replacement. Analysis of survival, complications, and quality of life]. / Geriatrische Patienten mit proximalen periprothetischen Femurfrakturen nach Prothesenschaftwechsel. Letalität, Komplikationsrate und weiterer Lebensweg.

BACKGROUND: The goal of treating proximal periprosthetic femur fractures in geriatric patients is a timely postoperative mobilization. The purpose of this study is to analyze the results after treating our patients by femoral stem exchange irrespective of fixation status. The study included 32 patients (2001-2009; mean age 82 years; Vancouver classification: 12 type B1, 16 type B2, and 4 type C). METHOD: Ambulatory status and activities of daily living pre- and postoperatively were compared. Retrospective data collection was performed by reviewing patients' charts. By interviewing patients, family members, and family physicians missing information was collected. RESULTS: A total of 22 patients (69%) achieved their pre-traumatic mobilization level; 22 of 26 patients (85%) were reintegrated into their pre-traumatic environment. A 16% (n=5) complication rate and an 87% 12-month survival rate were calculated. CONCLUSION: The concept of primary stable periprosthetic fracture care by using a revision prosthetic device potentially reduces complications related to postoperative non-weight-bearing without increasing the complication rate related to a more complex surgical procedure.

[Coronal fracture dislocation of the hamate and the base of the fourth metacarpal bone: a rare form of carpometacarpal injury]. / Koronare Spaltluxationsfrakturen des Os hamatum und der Os metakarpale IV-Basis: eine seltene Form der karpometakarpalen Verletzung.

Fractures of the hamate body and the base of the fourth metacarpal bone in the coronal plane with or without a dislocation of the base of the fifth metacarpal bone are rare. Clenched fist punches are considered to be the main cause. The diagnosis of the fracture dislocation is often missed on routine radiographs. Posterior-anterior, lateral, and oblique views are required for native radiological evaluation. A CT scan can help in the assessment of severity and for preoperative planning. Unless minimal displacement is present, non-surgical treatment does not lead to satisfying outcome. Displaced fractures of the hamate body and the base of the fourth metacarpal bone with or without subluxation of the hamatometacarpal joint should be stabilised by open reduction and internal fixation (ORIF). Controversy exists about the surgical treatment of choice. Screw or K-wire fixation with postoperative cast immobilisation for 6 weeks and consecutive hardware removal has been found to result in excellent clinical and radiological outcomes. This study presents 2 cases of coronal fractures of the body of the hamate and the base of the fourth metacarpal bone with subluxation of the hamatometacarpal V joint. Anatomy, epidemiology, classification, mechanism, clinical symptoms, diagnostic features, and therapy options for these injuries are discussed.

[Chopart dislocation--a simple diagnosis?]. / Chopart-Luxation--eine einfache Diagnose?

The case of an initially overlooked transligamentary Chopart dislocation following distorsion trauma of the foot is presented and the treatment and long-term course are discussed. A 55-year-old female patient sustained severe injury to the left foot after falling from a height of 4 m.. The instep was severely swollen and there was deformity with adduction of the forefoot and supination position. The peripheral pulse and sensitivity were intact. The conclusion from local radiographic investigations was that there were no signs of fracture or dislocation. The patient travelled home in pain 1 week after the accident and registered in the casualty department at our hospital. Assessment of the radiographs revealed a transligamentary Chopart dislocation with dorsolateral dislocation of the talus head, avulsed navicular fragments and a depressed fracture at the medial talus head. Treatment was initiated immediately after diagnosis with closed reduction and percutaneous K-wire fixation and 8 weeks immobilization in a lower leg plaster cast. Chopart dislocation is a rare consequence of accidental distortion trauma of the foot. Peritarsal dislocations represent approximately 15% of tarsal injuries and 1% of joint dislocations overall. Therefore, if a high energy accident has occurred, it is necessary to specifically search for dislocations and fractures. Immediate reduction reduces the risk of complications.

[Traumatic rupture of the triceps brachii tendon and ipsilateral Achilles tendon]. / Traumatische Ruptur der Triceps-brachii-Sehne sowie der ipsilateralen Achillessehne.

We report on a 71-year-old male farmer who sustained an injury to the tendons of the triceps brachii and the Achilles tendon on the left side. The diagnosis was based on clinical investigations and ultrasound. The triceps brachii tendon was repaired with open transosseous sutures. Six weeks after the operation we only allowed passive mobilization. The Achilles tendon rupture was treated with a semi-open procedure. Four weeks after the operation the ankle was fixed in 30 degrees plantar flexion, followed by 2 weeks in neutral position. Full weight bearing was allowed. Six months after the operation the patient no longer had any problems with his injury. Injuries of the tendon of the triceps brachii are very rare, with an incidence of 0.8%. We could not find case reports of a simultaneous injury to another tendon in the literature.

[Comparison between the diagnostic findings of esophago-gastro-bulboscopy and standard radiographic diagnosis]. / Zum Vergleich der diagnostischen Aussage von Osophago-Gastro-Bulboskopie und Standard-Röntgendiagnostik.

On the basis of a computer-supported evaluation of the data of 1,808 patients who underwent endoscopy (endoscopy of the superior alimentary tract) the comparison of X-ray-findings and findings of the endoscopy could be made in 887 patients. For 124 patients with an oesophageal and gastric tumour, respectively, and for 146 patients with a gastroduodenal ulcer a control of the findings by superordinate parameters (findings of operations and post-mortem examinations) are present. The result was an accordance between 90 and 98%. The accordance of the evidence of the two methods varies depending on the group of diagnosis. For the oesophageal carcinoma it is 90%, for the gastric carcinoma ca. 77%, for the ventricular ulcer and the duodenal ulcer in every case 70%, while the X-ray diagnosis "no abnormality discovered" could be endoscopically confirmed only in 56%. From this result necessary conclusions concerning the further concept of the diagnosis of diseases of the superior alimentary tract.

[The value of endoscopy in acute hemorrhage of the upper gastro intestinal tract]. / Zum Wert der Endoskopie bei akuten Blutungen des oberen Gastrointestinaltrakts.

1808 esophage-gastro-bulboscopies were performed, in 156 cases (8.0%) because of acute haemorrhage, from 1975 to 1979. In 14 cases (9.0%) no lesion could be detected. In 3 patients (1.9%) an exact localization of the bleeding lesion could not be attained. Gastric and duodenal ulcerations were (57.1%) the most frequent causes of haemorrhage, followed by erosive lesions (12.8%). Multiple bleeding sources were realized in 24 patients (15.4%). At present endoscopy is the initial method for diagnosing the causes of acute bleeding in the upper digestive tract.

[Diagnostic by angiography of soft tissue tumors of the extremities (author's transl)]. / Angiographische Diagnostik von Weichteiltumoren der Extremitäten.

The diagnostic efficacy of angiography in soft tissue tumors of the extremities (15 malign, 16 benign) has been examined. Each of the malignant processes could be diagnosed correctly. We obtained two wrong positive results in chronic inflammatory processes. Both cases showed several angiographically malignant criteria.
