The purpose of this study was to assess the impact of uniform anti-rotational proximal femoral intramedullary nail (APFN) use on patient mobility status with the treatment of two different unstable intertrochanteric femur fracture groups of geriatric patients. The study included patients aged > 65 years who underwent surgery with APFN. Group 1 comprised AO classification, AO/OTA 31-A22, and A23 patients, and group 2, A31 and A32 patients. The demographic data of the patients, postoperative complications, follow-up, mortality status, postoperative reduction, tip-apex distance (TAD), and the Parker-Palmer mobility (PPM) score were evaluated. There were no statistically significant differences between the groups in terms of gender, affected side, time from trauma to surgery, ASA score, anesthesia type, duration of hospitalization, duration of surgery, TAD values, reduction values, or mortality rate. The average age of patients in group 2 was significantly higher than that of patients in group 1 (p < 0.05). The mobility scores of group 1 patients were significantly higher than those of group 2 (p < 0.05). While no relationship was found between the TAD values and the reduction status of the cases, the PPM scores of the AO 31 A3 cases were determined to be significantly worse. Therefore, fractures with a preoperative classification of AO type 31 A3 can be expected to have worse results than A2 ITF fractures. The fracture type seems to have as great an effect as other factors on the postoperative mobility score.

The aim of the current study was to evaluate the sensitivity of the lever sign test and the widely used basic tests of the Lachman, anterior drawer and pivot shift tests, both under anaesthesia and without anaesthesia, according to the gold standard diagnostic arthroscopic results in patients undergoing anterior cruciate ligament reconstruction. The study included 117 patients, diagnosed with ACL tear which was definitively determined during an arthroscopic surgical procedure applied. Before anaesthesia and while under anaesthesia, the Lachman, anterior drawer, pivot shift and lever sign tests were applied to all patients. Evaluation was made of MR images for each patient and documented. The patients comprised 96 males and 21 females, witha mean age of 25.8 ± 5.9 years (range, 17–45 years). Total tear was determined in 82 cases, anteromedial (AM) bundle in 14, posterolateral (PL) bundle in 13 and elongation in 8. Pre-anaesthesia positivity was found in lever sign at 94.2 %, Lachman at 80.5 %, pivot shift at 62.3 % and anterior drawer at 60.1 %. These rates were determined after anaesthesia as lever sign 98.4 %, Lachman 88.7 %, pivot shift 88.3 % and anterior drawer 84.2 %. The lever sign test can be easily applied clinically and it seems to have higher sensitivity than the Lachman test which is the basis of classic information, it should be included in routine clinical practice. In the light of the results of this study, further studies are required to review the accepted view that the Lachmann test is the most reliable test.

Purpose: The aim of this study was to compare functional results before and after lunatum excision and scaphocapitate arthrodesis (SCA) using an angular stable circular plate in patients with Lichtman’s stage IIIB Kienböck’s disease. Methods: The study included nine patients (six females and three males) with a mean age of 33.2 ± 11 years (range: 18–54 years). Clinical and radiological assessment before and after surgery included wrist extension and flexion, range of motion and grip strength, visual analogue scale (VAS) score to assess pain, modified Mayo wrist scores, and measurements of the scapholunate (SL) angle and modified carpal height ratio. Results: The mean follow-up period was 17.33 ± 4.69 months (range: 12–24 months), mean operation time was 56.67 ± 12.5 min (range: 45–75 min) and mean hospitalization time was 3.44 ± 1.13 days (range: 2–6 days). Preoperative mean wrist extension was 23.89° ± 4.17°, mean wrist flexion was 32.22° ± 5.07°, mean grip strength compared to the healthy side was 34% (range: 28–37%) and mean VAS score was 7.6 (range: 7–8). Modified Mayo wrist scores were poor in all of the nine patients. Post-operative mean wrist extension was 27.78° ± 4.41°, mean wrist flexion was 40.56° ± 4.64°, mean grip strength compared to the healthy side was 71% (range: 63–81%) and mean VAS score was recorded as 1.4 (range: 1–2). Modified Mayo wrist scores were good in five and moderate in four patients. No patients had non-union or additional surgery. Conclusion: Lunatum excision and SCA using angular stable circular plate fixation provide pain relief with acceptable preservation of the range of motion.

Objective: The objectives of this study were to: (1) determine all the potential risk factors defined in the literature for cut-out after proximal femoral nail anti-rotation in managing intertrochanteric fractures and (2) make a reliable prediction about the likelihood of cut-out by developing a quantitative scoring system. Methods: Four hundred eighty patients who were operated on for an intertrochanteric femur fracture were included in the study. The patients were evaluated retrospectively. Radiological parameters known to affect cut-out, including tip apex distance (TAD), calcarreferenced TAD (CalTAD), and reduction quality, were also used to evaluate the patients. Additionally, the classification of the fracture according to the cortical thickness index for osteoporosis, the Charlson comorbidity index for additional comorbidities, and the Arbeitsgemeinschaft Für Osteosynthesefragen classification were evaluated. Results: The cut-out rate among all patients was 7.2%. Cut-out risk could be predicted by gender, TAD, CalTAD, and reduction quality. Female gender, TAD > 29.45, CalTAD > 31.75, and acceptable or poor reduction quality significantly increased the cut-out risk. Based on the chi-square analysis, it was determined that there was a significant relationship between the cut-out risk and the variables of TAD, CalTAD, reduction quality, gender, and fracture type (P=.000, P=.000, P=.000, P=.008, P=.016, respectively). Logistic regression analysis showed a strong correlation between the newly developed scoring system and the risk of cut-out. The risk of cut-out increased 8.1 times in individuals with a score of more than 2 (P < .001). Conclusion: Female gender, TAD > 29.45, CalTAD > 31.75, and acceptable or poor reduction quality are the parameters found to be significant in determining the cut-out risk. With the newly developed scoring system, risks can be calculated for all situations that may occur according to the scores obtained by the patients. The cut-out risk increases significantly in patients with a score above 2 points. Level of Evidence: Level III, Diagnostic Study.
