    Septocutaneous perforators of the peroneal artery relative to the fibula: anatomical basis of the use of pedicled fasciocutaneous flap
    Ozalp, T; Masquelet, AC; Begue, TC
    There are many studies describing the perforating branches of the peroneal artery but none of them identifies their locations relative to fibula. The aim of this study was to demonstrate the locations of the perforators relative to the fibula and to present a case, treated with an adipofascial flap, based on one of these small arteries. In this study, nine fresh male cadavers' legs injected with colored latex were dissected for demonstration of the longitudinal axis of these perforators. A large incision was made on the lateral part of the leg from the head of the fibula to the ankle. The peroneal perforating vessels were displayed. The posterior margin of the fibula was marked with needles from proximal to distal just above every perforator. The distance between the needle and the perforator was recorded. Their diameters were measured at the level of fascial emergence. There were four to seven perforating vessels; the larger vessels were near the proximal end of the fibula with an average of 1.1 mm and a minimum of 0.8 mm. We found that these branches were not parallel to fibula, but aligned in an oblique projection from posterior to anterior and from distal to proximal because of the course of the intermuscular septum between the soleus and peroneus longus muscles. The lowermost vessel was 1.7 cm away from the posterior margin of the fibula while the uppermost vessel was 0.25 cm away from the posterior ridge of the fibula. Adipofascial or fasciocutaneous flaps, which have important advantages in covering small to medium sized defects, can be based on the perforators of the peroneal artery. But for the centralization of the flap pedicle, the locations of the perforators, which are aligned from the lateral malleolus to the fibular head in oblique direction and from the posterior to the anterior must be taken into consideration. This knowledge is crucial for the flap design and the centralization of the vessels.

    Bilateral fracture of the pisiform bone
    Ozalp, T; Kurt, C; Coskunol, E; Ozdemir, O; Begue, T
    Fracture of the pisiform bone is exceptional compared with the other carpal bones. Such lesions may be missed in the emergency room because of the complex anatomy of the carpal region. The usual circumstances leading to fracture of the pisiform bone include fall with reception on the hyperextencled wrist, traffic accidents, and blunt trauma. The purpose of this work was to present a case of bilateral fracture of the pisiform bones. A 34-year-old woman presented with pain along the ulnar borders of both wrists after a fall. The mechanism of fracture was direct trauma on both hands after reception in radial inclination. The diagnosis was established late and conservative treatment was applied. After simple immobilization, the clinical and functional outcome was excellent. The anatomic position of the pisiform bone exposes it to direct trauma. Late diagnosis can favor osteoarthritic sequelae involving the pisotriquetral joint.

    Giant-cell tumor of the hand
    Ozalp, T; Yercan, H; Oku, G; Ozdemir, O; Coskunol, E; Bégué, T; Calli, I
    Purpose of the study Giant-cell bone tumors are benign but have great potential for recurrence. Frequently observed in epiphyseal areas of tubular bones, these tumors are rarely found in hand localizations. We examined the characteristic features of giant-cell tumors of the hand and analyzed the pertinence of surgical treatment. We noted complications, consequences of recurrence and later operations on the same tumor site in five cases. Case reports Five patients treated between 1973 and 2000 for giant-cell tumors involving the hand bones were reviewed retrospectively, Mean age was 41.6 years and mean follow-up was 7.8 years. The surgical procedure was curettage for two, curettage with bone graft for two and amputation for one. The Enneking score was noted. Results Pain was the main symptom, with local swelling in several cases. At 7.8 years follow-up recurrence was noted for four of the five tumors. Two patients were treated for a second recurrence. Amputation of the forearm was required for one recurrence affecting soft tissue. Mean time between two consecutive recurrences was three months. In all six episodes of recurrent tumor were treated. These five patients had a total of ten operations. There were no cases of metastasis nor multicentric foci. Discussion Treatment of giant-cell tumors involving the hand bones is designed to eradicate the tumor and also protect hand function while keeping in mind the aggressive nature of these benign tumors. Surgical alternatives for radical treatment can include wide resection, resection of the ray and amputation.

    Comparison of clinical outcomes and repair integrity after arthroscopic versus mini-open rotator cuff repair: An observational study
    Tosyali, HK; Kaya, H; Hancioglu, S; Tamsel, I; Orguc, S; Tekustun, F; Kayikci, K; Kucuk, L; Ozalp, T
    This study aimed to evaluate the differences between mini-open (MO) and arthroscopic (ART) repair procedures for rotator cuff tendon tears in terms of clinical and radiological outcomes. This retrospective study included 59 patients, and data were collected prospectively. Patients with full-thickness rotator cuff tears were randomized to undergo MO or ART repair at 2 centers by 2 surgeons between January 2012 and December 2017. Data were collected 3 weeks before surgery and 6 and 12 months after surgery. Physical function was assessed using the American Shoulder and Elbow Surgeons index, VAS, and Constant scoring system. Radiological outcomes were assessed using the Sugaya classification, adapted for ultrasound. Changes between baseline and follow-up were compared between the 2 groups. Fifty-nine patients who underwent ART or MO rotator cuff repair were included in this study. The 2 groups had similar demographic characteristics and preoperative baseline parameters. Both the MO and ART groups showed statistically significant improvement in outcome parameters (P <= .0001); however, cuff repair integrity was significantly better in the ART group (P = .023). All other improvements in the patient-derived parameters were equivalent. None of the patients in either group required revision surgery. According to the results of our retrospective study, MO and ART rotator cuff repair are effective and viable options for surgeons to repair rotator cuff tears. There were no differences in objective and subjective outcomes between the full ART and MO techniques for rotator cuff tears. Surgeons should choose a technique with which they are more familiar.

    A novel nerve transfer: The first palmar interosseous motor branch of the ulnar nerve to the recurrent motor branch of the median nerve
    Ozcelik, IB; Yildiran, G; Mersa, B; Sutcu, M; Celik, ZE; Ozalp, T
    Introduction: The recovery of recurrent motor branch of the median nerve might be delayed in high level median nerve injuries due to the long reinnervation distance. The aim of this study is to define a novel nerve transfer to restore the opposition and pinch. Methods: Two fresh frozen hand cadavers were used for the study. The motor branch of the first palmar interosseous muscle of the ulnar nerve was identified and dissected. Thenar branch of the median nerve was dissected from its insertion site. The motor branch of the first palmar interosseous muscle of the ulnar nerve was transferred to the thenar motor branch of the median nerve. Axon counts were examined histopathologically. Clinically this nerve transfer was performed for two female patients with a high-level median nerve injury. Mehta opposition scores were 21 and 20, respectively and the results were satisfactory six months after the surgery. Discussion: Although exploration and repair are recommended as the first treatment for median nerve injuries, the waiting time until the motor branch is reinnervated is critical in high level lesions. Nerve transfers become very important for fast recovery. Conclusions: This new nerve transfer proposal may be an important step in nerve transfer surgery. (C) 2020 Elsevier Ltd. All rights reserved.

    The effect of regional and general anaesthesia on cerebral oxygenation in shoulder arthroscopy
    Acikel, A; Topcu, I; Ozturk, T; Keles, GT; Ozalp, T
    Aim: Shoulder arthroscopy in the beach-chair position can negatively affect cerebral perfusion and oxygenation, and thus, neurocognitive function. In this study, we aimed to compare the effects of general and regional anaesthesia (GA and RA, respectively) on cerebral oxygenation in patients undergoing shoulder arthroscopy in the beach-chair position. Material and Methods: This prospective, randomized study included 60 patients who underwent shoulder arthroscopy in the beach-chair position. Patients were divided into two groups: (1) GA (n = 30), and (2) RA using an interscalene brachial plexus block (ISB; n = 30). All patients were laid supine prior to GA or ISB (T0), and after induction of GA or ISB (T1). Next, patients were placed in the beach-chair position. The right and left cerebral oxygen saturation (NIRS-R, NIRS-L, respectively), peripheral oxygen saturation (SpO2), heart rate (HR), and mean arterial pressure (MAP) values were recorded at T0 and T1, as well as 5 (T2), 10 (T3), 20 (T4), and 30 minutes (T5) after patients were placed in the beach-chair position. Results: Patient's clinical characteristics, initial laboratory findings, and perioperative data were similar in both groups. Compared to T0, MAP was significantly lower at T1, T2, T3, and T4 in the GA group. Tukey's HSD test indicated p<0.05, p<0.0001, p<0.0001, and p<0.001, respectively. Although NIRS-R and NIRS-L values fluctuated substantially, there were no differences between groups at any of the pre-defined time points. Discussion: ISB in the beach-chair position may better preserve cerebral oxygenation compared to GA.

    Reconstruction of diabetic foot ulcers by lateral supramalleolar flap
    Yercan, HS; Ozalp, T; Okcu, G
    Objective: To report a series of 8 diabetic patients in whom the reconstruction of large-sized defect of the foot was performed using lateral supramalleolar flap. Methods: Coverage of the soft tissue defect was carried out by a lateral supramalleolar flap in 8 patients who had large-sized, non-healing ulcers at the Celal Bayax University, Department of Orthopedics and Traumatology, Manisa, Turkey, between 1998-2003. The mean age was 54 years. Preoperatively Doppler flowmeter evaluation was performed, and the ischemic index was calculated in all patients. Results: The flaps survived except for one patient who had a large defect on the heel with low ischemic index. The average healing time of the ulcer region and recovery of regular walking status was 34 days. The average healing period of the donor site was 35 days. After the average follow-up period of 40 months, neither infection nor a recurrence of the ulcer was encountered. The major problem of the donor area was skin graft breakdown and its non-aesthetic appearance due to hypertrophic granulation tissue. Conclusion: The lateral supramalleolar flap is a reliable option for the reconstruction of large-sized diabetic ulcers involving the dorsal aspect of the foot. This can also be used in conjunction with local muscle flaps, such as abductor hallucis for covering deep and large heel defects when the sural neurocutaneous flap is contraindicated.

    Arthroscopic removal of the osteoid osteoma on the neck of the talus
    Yercan, HS; Okcu, G; Ozalp, T; Osiç, U
    Juxta-articular osteoid osteomas arising around the ankle are unusual. Tumors arising on the neck of the talus will commonly produce symptoms mimicking monoarticular arthritis or trauma. Patients are usually treated for arthritis or ankle sprain, which often leads to a delay in definitive diagnosis. We present an arthroscopic removal of an osteoid osteoma on the neck of talus, and review the literature.
