Serum prolidase activity and oxidative-antioxidative status in Legg-Calve-Perthes disease.

We aimed to find out that whether collagen turnover is altered in the context of Legg–Calve–Perthes disease (LCPD) by evaluating serum prolidase activity. We also investigated the correlation between collagen turnover and oxidative–antioxidative status in LCPD. Plasma prolidase activity, total oxidant status (TOS), total antioxidant capacity, and oxidative stress index (OSI) were determined for 39 patients with LCPD and 40 healthy controls. Serum prolidase activity, TOS, and OSI were higher, but TAC was lower in patients with LCPD compared with controls. Prolidase activity was positively correlated with TOS and OSI levels. Serum prolidase activity is significantly associated with LCPD.

Importance of the Upper Extremity Position for a Safe and Effective Axillary Block: a Comparative Study

OBJECTIVE Our aim was to determine the ideal position of upper extremities during ultrasonography guidance for axillary block. The position that provides the shortest distance between the median and musculocutaneous nerves was assumed to be the most appropriate position for axillary block. METHODS In this cross-sectional study, 120 (45 female and 75 male) patients were placed in a position with a shoulder at 90° / elbow 90° (position 1) and a shoulder 90° / elbow 0° (position 2). The intersection point of the biceps brachii muscle with the lower border of the pectoralis major muscle is defined as the proximal level (P). Distal level (D) is reffered as 5 cm below the proximal level. In the positions described above, the distance between median and musculocutaneous nerves was measured proximal (positions 1P and 2P) and distal levels (positions 1D and 2D). It was investigated whether these measurements differed between the groups and whether the body mass index or the gender. RESULTS The shortest mean distance (10.24±3.95 mm) between the two nerves was determined when the shoulder position 90°/elbow position 0° at the distal level (1D) and the longest mean distance (13.41±4.26 mm) was determined when shoulder position 90°/elbow position 90° at the proximal level (2P). In all four cases, there was no difference in the results between men and women. There was no relationship between the measurement results and the body mass indexes and age of the patients. CONCLUSION Appropriate positioning of the upper extremities is important for achieving optimal position during axillary block. Thereby, the procedure can be safely and effectively performed with lesser amounts of local anaesthetic solution and a decreased number of manoeuvres with needle during infiltration.

Bipolar dislocation of the forearm (floating forearm)

Bipolar dislocation of the forearm (floating forearm) is an unusual injury and is therefore often overlooked. We report a 28-year-old male patient who presented at another center with a history of a fall while climbing a tree. The patients left elbow was treated with closed reduction and immobilization with a long-arm cast brace due to elbow dislocation. However, the patient was admitted with pain and swelling of the wrist to our emergency department the following day. Physical and radiological examination revealed dorsal trans-scaphoid perilunate dislocation. A dorsal incision was performed for open reduction and internal fixation to provide wide surgical exposure. Concomitant occurrence of elbow dislocation and fracture-dislocation of the perilunate is infrequent. Therefore, physicians should be aware of possible additional injuries and current recommended treatment methods.

COULD OZONE TREATMENT BE A PROMISING ALTERNATIVE FOR OSTEOMYELITIS? AN EXPERIMENTAL STUDY

ABSTRACT Objective: The aim of the present study was to investigate the biochemical and histopathological impact of ozone treatment in an experimental model of osteomyelitis in rats. Methods: A total of 24 adult male Sprague-Dawley rats (3 months old, each weighing 300 to 400 g) were randomly allocated into three groups. Group I (n=8) served as a control and received no interventions or medications. In Group II (n=8), osteomyelitis was induced in the femur and no treatment was applied. Group III (n=8) received intraperitoneal ozone treatment for 3 weeks after the formation of osteomyelitis in the femur. Serum samples were taken to assess total antioxidant capacity (TAC), protein carbonyl content (PCO), and lactate dehydrogenase (LDH). Bone specimens obtained from the femur were histopathologically evaluated for inflammation, necrosis, osteomyelitis, and abscess formation. Results: Serum TAC levels were notably higher (p<0.001), while LDH levels were lower (p=0.002) in Group III than Group II. No significant difference was detected between groups with respect to PCO level. Similarly, Group III displayed more favorable histopathological outcomes with respect to osteomyelitis (p=0.008), inflammation (p=0.001), necrosis (p=0.022), and abscess formation (p=0.022). Conclusion: Ozone may be a useful adjunct treatment for osteomyelitis. Further studies in animals and humans are needed to clarify and confirm these preventive effects, understand the underlying pathophysiology, and establish guidelines.

Injury of the Infrapatellar Branch of the Saphenous Nerve During Hamstring Graft Harvest Comparison of two Different Incision

Objectives: Sensory disturbance around the surgical incision due to injury of the infrapatellar branch of the saphenous nerve (IPBSN) can be seen in the anterior cruciate ligament (ACL) reconstruction after the operation. In this research, we aimed to compare the incidence, extent of sensory loss, its clinical effect and natural course caused by two different skin incisions used for autogenous hamstring graft harvest during ACL reconstruction. Methods: Seventy eight patients who underwent hamstring graft harvest during ACL reconstruction participated in the study. Among the 78 patients, vertical incision for 36 patients and oblique incision for 42 patients were used for graft harvest. The area of the sensory loss was documented at 6 weeks, 3 months and 6 months follow-ups. A blunt pin was used for pin prick examination starting from proximal end of the incision and the patient was asked to note the point of change in sensation from normal to abnormal. The abnormal points were joined and digital photographs of hypesthesia were taken and analysed by computer for area detection. The length of incision and subjective complain of sensory loss were also noted. Results Results: The patients’ age and incision length between the two groups had no significant difference. At 6 weeks, vertical incision was associated with persistent sensory loss in 77% (28/36) cases which was significantly higher when compared to the oblique incision (19/42). The measured area of hypesthesia was significantly higher in vertical incision (42.4±22.3 cm2) than that in oblique incision (9.3±15.3 cm2) at 6 weeks. On further follow-ups at 3 and 6 months, the area of hypesthesia gradually shrunk in size. The recovery pattern was from distal to proximal in direction. Also, subjective cutaneous anaesthesia was higher in vertical incision (15/36, 41%) than oblique incision (6/42, 14%) at 6 months. Conclusion: Injury to the IPBSN can be seen during hamstring graft harvest. Vertical incision has maximum incidence of IPBSN injury. Oblique incision with less risk of nerve damage may be better for graft harvesting in ACL reconstruction. Area of hypesthesia gradually reduces with time and even recovers totally. Sensory loss does not impair normal daily activities in most of these patients. As a possible complication, nerve injury and its benign prognosis should be explained to the patient before surgery.
