The aim of this study was to evaluate the clinical and radiological results of patients with acute type III Rockwood acromioclavicular joint (ACJ) dislocation treated surgically by employing tension band wiring. The study included 24 patients with traumatic type III ACJ dislocations according to the Rockwood classification. The clinical and radiological outcomes of patients were assessed at the final follow-up visit. Implant failure and reduction loss were assessed using radiographs, whereas the Constant-Murley scoring system was used to assess the patients clinically. The mean follow-up period was 3.5 ± 1.3 years (range: 1-6 years). The mean age of the patients was 41.8 ± 11.7 years (range: 19-64 years) and the mean length of hospital stay was 2.3 days (range: 1-6 days). The fixation material was removed postoperatively at an average of 7.2 ± 9.9 months (range: 3-40 months). At the end of the follow-up period, the mean Constant-Murley score was 72.5 ± 12.8 (range: 50-90). The ACJ reduction was stable in 13 (54.2%) patients. Residual subluxation was detected in 11 (45.8%) patients. Distal clavicular osteolysis was noted in six (25%) patients. Acromioclavicular osteoarthritis was detected in five (20.8%) operated shoulders on follow-up radiographs. During the follow-up, Kirschner-wire migration and breakage occurred in four (16.6%) and seven (29.1%) patients, respectively. This study showed that surgical treatment with the tension band wiring method provided functionally satisfactory results even if complications developed because of the presence of implants. Independent of age, we can recommend it as the primary treatment method for patients who do not have very high expectations regarding their shoulder function. Additionally, we think that reducing the duration of implant retention will reduce the incidence of complications.

Diabetes mellitus (DM) is a major global health problem, and its incidence is growing. Depending on this increase, the number of diabetes-related complications will also rise. This study aimed to determine the risk factors associated with major and minor amputations resulting from diabetes. Patients diagnosed with diabetic foot complications (n = 371) and hospitalized between January 2019 and March 2020 were retrospectively evaluated using information obtained from the database of Diabetic Foot Wound Clinic. Examination of the data identified 165 patients for inclusion in the study, who were stratified into major amputation (group 1, n = 32), minor amputation (group 2, n = 66) and non-amputation (group 3, n = 67) groups. Of the 32 patients who underwent major amputations, 84% had a below-knee amputation, 13% had an above-knee amputation and 3% had knee disarticulation. At the same time, 73% of 66 patients who underwent minor amputation had a single-finger amputation, 17% had a multiple-finger amputation, 8% had a transmetatarsal amputation, and 2% had Lisfranc amputation. Laboratory results showed high acute phase protein and low albumin (ALB) levels in patients from group 1 (p < 0.05). Although Staphylococcus aureus was found to be the most common infectious agent, Gram-negative pathogens were dominant (p < 0.05). Also, there was a significant cost difference between the groups (p < 0.05). Furthermore, those aged over 65 had a high Wagner score, high Charlson Comorbidity Index (CCI), long diabetic foot ulcer (DFU) duration, and high white blood cell (WBC) count, all of which were risk factors for major amputation (p < 0.05). This study demonstrated an increased Wagner staging and incidence of peripheral neuropathy (PN) and peripheral arterial disease (PAD) in major amputation patients. In addition, the rate of distal vessel involvement was high in major amputation patients, with elevated acute phase proteins and low ALB levels crucial in laboratory findings.
Medial femoral condyle malunion in the coronal plane is a very rare injury. In this presented case, we performed intra-articular corrective osteotomy for a malunited medial femoral condyle in the coronal plane of a 22-year-old man and obtained good functional and radiographic results. Corrective osteotomy for a malunited medial Hoffa fracture is technically very challenging, but intra-articular corrective osteotomy for these malunited fractures offers a good outcome and should be considered as a salvage treatment.

Background: Dissociation is a special type of dislocation that is rarely seen in bipolar hemiarthroplasty. Objectıve: To investigate the clinical and biomechanical causes of dissociative dislocation of acetabular cup components in the hips of patients after bipolar hemiarthroplasty (BHA). Methods: BHA heads were divided into three groups according to their design. Cam-out and pull-out biomechanical tests were conducted to investigate the separation strengths of the BHA heads. Results: Among the 1684 BHA surgeries performed, the revision surgery rate was 4% (68 hips) and dissociation rate was 0.8% (15 hips). According to the cam-out test result, the highest values in the parameters ultimate force (F max ) ultimate torque (T), vertical displacement at maximum force (δ m ), rotation at maximum force (ϕ m ), maximum principal strain (Ɛ max ), minimum principal strain (Ɛ min ), average normal strain (Ɛ av ), maximum shear strain (γ max ), uniaxial normal strain (Ɛ un ) were detected in Type 2 BHA head. The pull-out values of the implants were sufficient to prevent the distraction force that may occur on the implant due to manual traction applied to the hip dislocations. However, in closed reduction maneuvers, cam-out-shaped deformation forces may cause dissociation in Types 1 and 3, but not in Type 2 BHA heads. According to the pull-out test results, while high values were detected in the parameters Fmax and stiffness ( k ) in the Type 2 BHA head, δm and maximum force (E) parameters were found to be high in the Type 1 BHA head. In the cam-out test, a strong positive relationship was found between the thickness and width of the polyethylene locking ring and F max , T, δ m , ϕ m , Ɛ max , γ max , Ɛ un . Conclusıon: Better BHA head designs and polyethylene designs may help resolve the rare problem of dissociation, which almost always leads to resurgical procedures.
Increasing life expectancy has led to a rise in hip fractures and an associated increase in hemiarthroplasty procedures aimed at restoring mobility and preventing muscle loss. Despite the extensive literature on failed hemiarthroplasty, limited data address the influence of pre-operative fracture types—intracapsular versus extracapsular—on outcomes, including inpatient mortality. This study investigates the revisions of uncemented bipolar hemiarthroplasties concerning fracture type and identifies risk factors for inpatient mortality. This retrospective cohort study included 68 patients (16 males and 52 females) who underwent revision of uncemented bipolar hemiarthroplasties at a single institution between 2017 and 2024. Data on demographics, comorbidities, fracture type, surgical details and outcomes were analysed. Statistical analyses included t tests, chi-square tests and logistic regression, with significance set at p < 0.05. Of 1,690 hemiarthroplasties performed, 68 required revision (revision rate: 4%). Revisions for extracapsular fractures were associated with a higher prevalence of diabetes mellitus (p = 0.01) and elevated Almelo Hip Fracture Score (AHFS; p = 0.01). The overall inpatient mortality rate was 19%, significantly higher in males (43.75%) than females (11.54%; p = 0.00). Deceased patients demonstrated higher AHFS and American Society of Anaesthesiologists scores but lower Parker Mobility Scores (p = 0.01). Prolonged intensive care unit (ICU) stays were also linked to increased mortality (p = 0.02). Logistic regression identified male sex as an independent predictor of mortality (odds ratio: 9.37; p < 0.05). Pre-operative fracture type significantly influences revision outcomes in failed hemiarthroplasties. Moreover, extracapsular fractures are linked to diabetes mellitus and higher AHFS, whereas male sex, ICU stay duration and comorbidity scores predict inpatient mortality. These findings highlight the need for tailored perioperative care to mitigate risks. Not applicable.
Background and Objectives: This study aimed to evaluate the factors influencing early postoperative mortality in patients undergoing cementless hemiarthroplasty for proximal femoral fractures. Materials and Methods: The medical records of 227 patients treated between January 2019 and December 2020 were retrospectively reviewed. Patients were divided into two groups: survivors (Group 1, n = 160) and non-survivors (Group 2, n = 67). The variables assessed included demographic data, neutrophil-to-lymphocyte ratio, surgical duration, hospital stay, American Society of Anesthesiologists (ASA) score, cardiac ejection fraction (EF), Charlson Comorbidity Index (CCI), osteoporosis status, and hemoglobin and albumin levels. Clinical evaluation was performed using the Harris Hip Score. Binary logistic regression was used to analyze risk factors; receiver operating characteristic (ROC) analysis was applied to determine cutoff values. Results: The mean follow-up duration was 14.03 ± 10 months. The mean ages were 80 ± 7.68 yr in Group 1 and 83.99 ± 7.42 yr in Group 2. Statistically significant differences were found between groups regarding ASA scores, intensive care unit (ICU) admission rates, and osteoporosis status (p < 0.001). Preoperative and postoperative albumin levels were also significantly different (p < 0.001). The 1-year and 6-month mortality rates were 39.6% and 29.5%, respectively. Univariate analysis identified age, EF, ASA score, preoperative and postoperative albumin levels, CCI, ICU admission, and ICU stay duration as mortality-related factors. Multivariate binary logistic regression analysis revealed that low postoperative albumin levels may have a significant effect on mortality at 1, 3, and 6 months. ROC analysis showed a significant albumin cutoff value of 2.95 g/dL. Conclusions: Higher postoperative albumin levels were inversely associated with early mortality following hemiarthroplasty in elderly patients. Perioperative monitoring of albumin levels may help improve outcomes, particularly in individuals with severe comorbidities.
