Article Synopsis
  • - This study assessed the effects of the pain medications phenyramidol and diclofenac on bone healing in a rat model of femur fractures, focusing on radiological, histological, and biomechanical evaluations over time.
  • - A total of 72 male rats were divided into groups receiving different treatments (phenyramidol, diclofenac, both, or none) and were examined at various postoperative intervals (15, 30, 45 days) for their healing progress.
  • - The findings indicated that both medications alone hindered fracture healing, but their combined use was somewhat less detrimental. While there were some differences in healing outcomes among the groups, overall, histological assessments showed no significant improvement in bone healing with either medication

This case report presents the detailed clinical and radiological findings of a 63-year-old male patient who presented with right shoulder pain. Magnetic resonance imaging (MRI) and magnetic resonance arthrography (MRA) revealed significant tears in most of the rotator cuff muscles. Despite these findings, the patient was able to perform full shoulder movements, suggesting that aponeurotic expansion may play a crucial role in this scenario.

Purpose: This study aimed to compare the effectiveness of Pulsed Radiofrequency Ablation (PRFA) and surgery for treating chronic plantar fasciitis, focusing on pain relief and functional outcomes.

Methods: A prospective study involved 30 patients with chronic plantar fasciitis unresponsive to 12 months of conservative treatment. Patients were divided into PRFA (n = 17) and surgical (n = 13) groups.

Purpose: In this study, we aimed to investigate the effects of hyperbaric oxygen therapy and enoxaparin sodium, which are known to accelerate bone tissue healing as well as tendon and soft tissue healing, on the healing of Achilles tendon rupture.

Methods: Thirty-six rats were used in the present study. All rats were divided into groups of nine.

: This study aimed to determine the relationship between non-simultaneous contralateral hip fractures, urban and rural differences, fracture localization, time between fractures, physiotherapy applications, comorbidity, and the second fracture outcomes. : We retrospectively analyzed 107 patients aged 65 and older with proximal femur fractures (PFFs) who underwent surgery at Düzce University Medical Faculty between January 2010 and December 2022. High-energy fractures, pathological fractures, and patients with a history of old fractures were excluded.

Article Synopsis
  • Fracture healing involves complex interactions among physical, biological, and chemical factors, and although research is growing, its mechanism is not completely understood.
  • This study examined the effects of the COVID-19 treatments favipiravir and hydroxychloroquine on fracture healing using 48 male Wistar rats, which were analyzed at the 2nd and 4th weeks for radiological and histological changes.
  • Results showed a significant early negative impact of favipiravir on bone repair, but potential positive effects later on, while hydroxychloroquine did not significantly influence fracture healing.

Although the Achilles tendon is the largest and strongest tendon in the body, healing of the Achilles tendon is the most common injury, and this process is difficult due to poor tendon circulation; moreover, the underlying mechanism has not been fully elucidated. In our study, we aimed to investigate the effects of pentoxifylline and alpha-tocopherol administered separately or in combination on rats with Achilles tendon injury. Forty-eight male Wistar rats weighing 230 ± 30 g were used in the study.

Objectives: In this study, we aimed to investigate the morphological and histological effects of tranexamic acid (TA) on wound healing in a rat wound model.

Materials And Methods: A total of 24 adult male Wistar Albino rats were used in this study. All rats were simple randomly divided into three groups including eight rats in each group.

Objective: Acute and chronic osteomyelitis generally require long-term antibiotic therapy and surgical debridement. Implant-associated osteomyelitis, particularly from methicillin-resistant Staphylococcus aureus (MRSA) strains, is difficult to treat. Rifaximin is an antibiotic derived from rifamycin which may be effective in the treatment of osteomyelitis in terms of its wide spectrum of action and pharmacological properties.

Background: Inadequate intestinal perfusion resulting from hemorrhagic shock negatively affects wound healing. In this experimental study, we aimed to evaluate the effects of resuscitation with hypertonic saline on colonic anastomosis in rats with controlled hemorrhagic shock.

Methods: A total of 24 male Wistar albino rats weighing between 200 and 250 g were used in this study.

Cryotherapy is a method of treatment using cold application. This study aimed to evaluate postoperative clinical and hematological parameters and pain associated with total knee arthroplasty in patients and compared cryotherapy to the conventional method of cold ice pack compressions. Between January 2015 and January 2016, 90 patients who underwent total knee arthroplasty for grade 4 gonarthrosis were prospectively evaluated.

Purpose: Despite the improvements in the repair equipment techniques of rotator cuff, a gold standard method has not been defined yet and transosseous fixation through deltoid-splitting (mini-open) approach is still regarded as a good option. The primary purpose of this study is to present satisfactory clinical and functional outcomes with a novel transosseous device in full-thickness rotator cuff tear through deltoid-splitting.

Materials And Methods: This retrospective study was performed on 70 consecutive patients who underwent surgery by a single surgeon from June 2014 to June 2016 for a full-thickness rotator cuff tear and was managed with a novel transosseous device.

Purpose: The position of the patella according to the femur is very important in the evaluation of patella-femoral joint disorders. In 1938, Blumensaat (BS) described the BS line to evaluate the patella femoral congruence. This method is still valuable in clinical use.

Hallux valgus is a complex deformity of the first metatarsophalangeal joint characterized by varus deformity of the first metatarsal bone, valgus deformity of the big toe, and lateral deviation of the extensor tendons and sesamoid bones. Several surgical methods have been described for correction of the deformity. Different materials have been used for the fixation of osteotomy.

Purpose: oil possesses a well-known ability to protect certain organs from oxidative, neoplastic, and inflammatory damage. This study investigated the potential chondroprotective effects of intraarticular injections of oil in a rabbit osteoarthritis model.

Methods: Osteoarthritis models were created by performing anterior cruciate ligament transections in 20 New Zealand rabbits.

: Supracondylar humerus fractures are common in children andcan be surgically treated. However, the general surgical procedures involving reduction andfixation might lead to reduction loss, failure to direct the Kirschner (K)-wire toward the desiredposition, prolonged surgery, or chondral damage. This study aimed to show that temporaryfixation of closed reduction with a fabric adhesive bandage in pediatric supracondylar humerusfractures could maintain reduction so that surgical treatment can be easily performed by a singlephysician.
