Item Midterm Clinical Outcomes Of Collateral Ligament Repair Of The Thumb And Lesser Digits: A Retrospective Analysis Of 35 Cases(2022) Sahin, Mehmet Sukru; 10.1186/s12891-022-05605-1Background Finger collateral ligament injuries are common, and conservative treatment usually works well. However, complete ruptures that lead to instability could cause painful disability. This study presents our clinical experience and a qualitative functional evaluation following the surgical repair of the thumb and proximal interphalangeal (PIP) joint collateral ligament ruptures. Methods Thirty-five patients (22 men and 13 women), diagnosed via a physical examination and magnetic resonance imaging (MRI) with a total collateral ligament rupture in the metacarpophalangeal thumb (16) and PIP joints of the lesser digits (19) and treated surgically, were evaluated retrospectively. The limited range of motion; functional score by Saetta; disabilities of the arm, shoulder, and hand (DASH) score; pre- and post-operative pain, deformity level; and post-operative ability to grip keys, buttons, and jars were measured. The significance of the change between the pre and post-operative visual analog scale for pain (VAS) scores were evaluated using the Wilcoxon signed-rank test. The difference between the lesser digits and thumb groups by patient age was evaluated using the Mann-Whitney-U test. All data, such as the mean, range, and standard deviation, were calculated using SPSS. Results The mean pre- and post-operative VAS scores were 4.8 (from 3 to 7) and 0.91 (0 to 4), respectively. The mean post-operative limitation in the range of motion was 9.78 degrees (s = 14.47) for lesser digits and 6.87 degrees (s = 12.29) for the thumb. According to Seatta et al., the final functional score was 62.5% excellent, 25% good, and 12.5% moderate for the thumb and 84.2% excellent, 10.5% good, and 5.3% poor for the lesser digits. The mean post-operative DASH score was 13.55 (SD: 8.77) for lesser digits and 14.22 (SD: 8.9) for the thumb. The mean contralateral (healthy) hand DASH score was 0.75 (SD: 1.05) for lesser digits and 0.75 (SD: 1.05) for the thumb. For the thumb and lesser digits, the z-scores were - 3.55 and - 3.787, respectively, and the progress of the VAS score was significant (p < 0.05). Conclusion After a 40-month follow-up for 35 acute, subacute, and chronic cases, the results suggest that direct and suture-anchor repairs are feasible, painless treatments associated with good finger function.Item Is simple decompression enough for the treatment of idiopathic cubital tunnel syndrome: A prosoective comparative study analyzing the outcomes of simple decompression versus partial medial epicondylectomy(2020) Sahin, Orcun; Haberal, Bahtiyar; Sahin, Mehmet Sukru; Demirors, Huseyin; Kuru, Ilhami; Tuncay, Ismail Cengiz; 0000-0002-2457-0935; 0000-0001-5856-8895; 0000-0001-7677-8423; 0000-0002-1268-1451; 0000-0002-6035-6258; 0000-0002-1668-6997; 32962585; AAJ-5273-2021; AAF-3988-2021; AAJ-9972-2021; AAJ-4341-2021; AAF-4032-2021; W-9080-2019Objectives: This study aims to compare the clinical and functional outcomes of simple in-situ decompression and partial medial epicondylectomy for the treatment of idiopathic cubital tunnel syndrome (CuTS). Patients and methods: Between March 2014 and December 2016, 71 patients (31 males. 40 females: mean age 46.7 years: range. 38 to 62 years) with CuTS scheduled to undergo simple in-situ decompression (group 1) or partial medial epicondylectomy (group 2) were prospectively reviewed. All patients were analyzed with clinical examination (Tinel sign. Froment's and Wartenberg's signs, elbow flexion test, subluxation), and McGowan scores before and after surgery. Final outcomes were reviewed with Wilson and Krout grading system. Results: There was no significant difference between the study groups in regard to Wilson and Krout grading and McGowan scores postoperatively. Group 1 had significantly better grip and key pinch strength values compared to group 2 at the final follow-up control. Conclusion: In-situ decompression and partial medial epicondylectomy represent efficient and safe methods for the treatment of idiopathic CuTS. When their efficiency is compared. in-situ decompression had better grip and key pinch strength values and more excellent outcomes compared to partial medial epicondylectomy.Item Hypothenar hammer syndrome: a case series and literature review(2015) Sahin, Mehmet Sukru; Ozyurekoglu, Tuna; Cakmak, Gokhan; 25741914Objectives: This study aims to report our experience regarding patients who were surgically treated due to hypothenar hammer syndrome and review the related literature. Patients and methods: The study included 11 hands of eight patients (5 males, 3 females; mean age 48 years; range 29 to 60 years) who underwent surgery due to hypothenar hammer syndrome between September 2004 and March 2013. Mean follow-up period was 50 months (range 3-103 months). The time of symptom onset, occupational history, and detailed physical examination findings were recorded. Surgery was performed under sedation and axillary anesthesia. Distal segment of the forearm, all thrombosed segments of the Guyon and superficial arch were removed. Reconstruction of the ulnar artery and the superficial arch was performed using vein grafts obtained from the forearm. Results: While all patients' dominant hand was affected, both hands were affected in three patients. All patients complained of pain and color change in one finger or multiple fingers. While minimal amputation and debridement of fingertip pulp was performed in two patients, all other patients recovered uneventfully. Patency of the ulnar artery was uneventful at follow-up in five of the eight patients, whereas three patients were performed revision surgery for a new vein graft. Most patient complaints resolved during the follow-up period. Conclusion: Hypothenar hammer syndrome is a disease of the upper extremities that should be considered in patients with digital ischemia, and a history of manual labor and smoking. Although this disease can be treated with conservative therapy, advance-stage patients who fail to respond to conservative treatment can be treated surgically with vein grafts.Item Effect of pentoxifylline on healing of segmental bone defects and angiogenesis(2015) Cakmak, Gokhan; Sahin, Mehmet Sukru; Ozdemir, B. Handan; Karadeniz, Emre; 26511696Objective: The aim of this study was to determine the effect of pentoxifylline (PTX) on angiogenesis and the healing of a critical-sized segmental defect of the radius diaphysis in a rat model, using radiological and histological grading systems. Methods: The study included 24 female Sprague-Dawley rats (weight: 300 +/- 20 g) divided into 4 groups. A critical-sized segmental defect was created in the radius diaphysis in all rats. In Group 1, morcellized iliac crest autografts were used to fill the segmental bone defect. In Group 2, segmental bone defects were filled using morcellized iliac crest autografts, and 25 mg/kg/day PTX was applied intraperitoneally. In Group 3, the segmental bone defects were not filled, and in Group 4 the segmental bone defects were left unfilled, and an intraperitoneal (IP) dose of 25 mg/kg/day PTX was applied. Rats were sacrificed at postoperative Week 8, and defects were evaluated using radiographic, histological and immunohistochemical methods. Results: There were significant differences between Group 1 and 2 according to radiological evaluation (p = 0.003) and quality of union at the defect site (p = 0.01). Union quality was higher in Group 4 than Group 3 (p = 0.01). Cluster of differentiation 31 (CD31) and vascular endothelial growth factor (VEGF) levels were higher in Group 2 than in Groups 3 and 4. Conclusion: According to radiological and histological parameters, PTX appears to improve angiogenesis and healing of segmental cortical bone defects of the radius in a rat model.Item Demographic Characteristics, Anatomical Distribution, and Clinical Presentations of Lipomatosis Tumors Arising from Hand and Wrist(2016) Sahin, Mehmet Sukru; Ergun, Adviye; Akin, Aslan; Kitis, Ali; 0000-0001-7677-8423; 27999457; AAJ-9972-2021The aim of this study is to analyze demographic characteristics, anatomical distribution, and clinic presentations of the lipomatosis masses in hand and wrist. The hand and wrist magnetic resonance (MR) images of 2,453 patients were evaluated retrospectively. Nineteen cases were included in the study that is seen fat component in mass in MR images. Patients' age, sex, and clinical symptoms were noted. The size and the localization area of the mass were evaluated. Ordinary lipomas were detected in 18 (95%) patients, and fibrolipomatous hamartoma of the median nerve was detected in 1 patient (5%). Benign ordinary lipomas were most frequently observed in palmar and ventral sides. Lipomas located in palmar area tend to be bigger size comparing with other locations. Deep-seated lipoma is localized in central area frequently. In ordinary lipoma cases, patients are generally (78%) asymptomatic. The most frequent clinical symptom is limitation in movement depending on mass dimension.
