Two-staged management of ankle fracture-dislocations with a posterior fragment: computer-tomography-based classification, treatment and its outcome.

INTRODUCTION: Trimalleolar fractures are difficult to treat and malreduction can lead to functional impairment. Involvement of the posterior malleolus has a poor predictive value. Current computed-tomography (CT)-based fracture classifications led to an increase in fixation of the posterior malleolus. The aim of this study was to describe the functional outcome after a two-stage stabilisation with direct fixation of the posterior fragment in trimalleolar dislocation fractures. MATERIALS AND METHODS: In a retrospective study, all patients presenting with a trimalleolar dislocation fracture, an available CT scan, and a two-stage operative stabilisation including the posterior malleolus by a posterior approach were included. All fractures were treated with initial external fixator and delayed definitive stabilisation including fixation of the posterior malleolus. Next to clinical and radiological follow-up, outcome measures (Foot and Ankle Outcome Score (FAOS), Numeric Rating Scale (NRS), Activity of Daily Living (ADL), Hulsmans implant removal score) and complications were analysed. RESULTS: Between 2008 and 2019, of 320 trimalleolar dislocation fractures, 39 patients were included. Mean follow-up was 49 months (standard deviation (SD) 29.7, range 16-148). Mean age was 60 years (SD 15.3, 17-84) with 69% female patients. The mean FAOS was 93/100 (SD 9.7, 57-100), NRS 2 (interquartile range (IQR) 0-3) and ADL 2 (IQR 1-2). Four patients showed a postoperative infection, three re-operations had to be performed and implants were removed in 24 individuals. CONCLUSION: A two-stage procedure of trimalleolar dislocation fractures with in-direct reduction and fixation of the posterior tibial fragment through a posterior approach leads to good functional outcome scores with a low rate of complications.

Osteosynthesis of scapular fractures: a retrospective cohort study.

PURPOSE: In recent years a trend from conservative to operative treatment of displaced scapula fractures has evolved. The aim of this study was to assess surgical and patient-based radiological and functional outcome after open reduction and internal fixation (ORIF) of displaced scapula fractures following predefined operative indications. METHODS: We retrospectively analyzed data of a consecutive series of patients with displaced scapula fractures following operative fixation at our institution between 06/2010 and 02/2020. The primary endpoint was a functional outcome using the QuickDASH score. Secondary outcomes were the Subjective Shoulder Value (SSV), numeric rating scale (NRS) for pain, Activities of Daily Living score (ADL) and complications. RESULTS: Twenty-six male patients were treated operatively. Twenty-three of whom were available for follow-up after a median follow-up time of 33 months (interquartile range [IQR] 8-70 months). In 18 (69%) cases a standard open approach and in 8 (31%) cases a minimal invasive (MI) approach was used. The median QuickDASH was 0 (IQR 0-0) with a median SSV of 95 (IQR 90-98). Patients reported a median NRS of 0 (IQR 0-1) and a median ADL score of 1 (IQR 1-1). Radiological fracture union was 100% without the occurrence of implant failure or mal-union. Two patients (7.7%) required early correction osteosynthesis, one patient (3.8%) developed a frozen shoulder 3 months postoperatively, and one patient (3.8%) presented with a superficial wound infection. CONCLUSION: Following previously published indications for ORIF of displaced scapula body and neck fractures a good functional outcome and a low rate of complications could be achieved.

Lateral approach for intramedullary nailing of displaced midshaft clavicle fractures; a retrospective cohort study.

PURPOSE: Midshaft clavicle fractures represent about 4% of all fractures in the emergency department. Non-operative treatment of displaced midshaft clavicle fractures (DMCF) can result in a relatively high non-union rate. Several operative techniques, including intramedullary fixation (IMF) using elastic stable intramedullary nailing (ESIN), have therefore been established. IMF through the medial approach is less suitable for fractures of the lateral diaphysis. IMF of DMCF of the lateral diaphysis through a lateral approach can be an alternative approach for these fractures. The aim of this study is to describe the technique of IMF from the lateral side and to present the functional outcome and complications. METHODS: A retrospective cohort study was performed. All patients with a traumatic DMCF treated with IMF using ESIN through a lateral approach between 2014 and 2019 were included. Endpoints were the functional outcome (QuickDASH, Subjective Shoulder Value (SSV)), pain (numeric rating scale (NRS)), daily impairment (activities of daily living (ADL)), complications and implant removal. RESULTS: Forty out of 43 patients were available for follow-up. Mean follow-up was 37 months. Mean age was 24 years (range 13-70). The median QuickDASH score was 0 (IQR 0.0-0.0) and the median SSV was 100 (95-100). The median ADL score was 1 (1-4) and the median NRS was 0 (0-0). No non-union occurred. Implant related irritation occurred in 11 patients (27.5%). Implants were removed in a total of 38 (95%) patients; in 10 cases due to irritation, in 28 cases routinely or on patient's request. CONCLUSION: IMF of DMCF of the lateral diaphysis through a lateral approach leads to excellent functional results and seems to be a suitable option for internal fixation. However, as with IMF from the medial side, it is not without complications and implant-related irritation.

Haemophilus haemolyticus: an atypical pathogen of septic arthritis of the knee joint.

Septic knee arthritis is a common disease, mostly due to bacterial infections. We describe a rare case of Haemophilus haemolyticus causing unilateral septic arthritis of a native knee. The affected patient presented with persistent severe knee pain after repeated intra-articular injections. Patient history included knee arthroscopy and a known rheumatoid arthritis treated by steroids. Since conservative treatment was ineffective and infection could not be excluded, diagnostic arthroscopy was performed. Synovial fluid and biopsies verified the uncommon microorganism and antibiotic therapy was initiated. Clinical findings and blood results showed rapid improvement. The patient was discharged in a good condition after 6 weeks. A review of the current literature describes only one joint infection with H. haemolyticus as underlying cause. In immunocompromised patients with septic knee arthritis also atypical pathogens must be considered. Nevertheless, the established treatment algorithm with arthroscopy and anti-infective therapy seems to be effective leading to satisfactory results.

Retroperitoneal perforation of a duodenal diverticulum containing a large enterolith after Roux-en-Y bypass and cholecystectomy.

Roux-en-Y gastric bypass (RYGB) is one of the most frequently performed bariatric procedures worldwide. The postoperative incidence of cholelithiasis after RYGB is higher than in the general population (30% vs. 2-5%), because the altered anatomy may lead to impaired gallbladder motility and biliary stasis. We report the case of a 47-year-old female who presented 9 years after RYGB and cholecystectomy with acute pain in the upper abdomen because of a retroperitoneal perforation of a duodenal diverticulum. Intraoperatively, a huge enterolith was found in the diverticulum and removed via duodenotomy. We claim that the stone grew during the sober states as the bile accumulated locally, because the gall bladder has already been removed and no duodenal food passage remained. This acute and life-threatening situation was successfully managed by operation. Consequently, a duodenal diverticulum has to be considered as a possible but very rare complication after RYGB and cholecystectomy.
