[Effects of intraarticular tramadol, magnesium and ketamine on postoperative pain in arthroscopic meniscectomy]. / Efeitos de tramadol, magnésio e cetamina por via intra­articular sobre a dor pós­operatória em meniscectomia artroscópica.

OBJECTIVE: Postoperative pain control is important in terms of early recovery and rehabilitation in arthroscopic meniscectomy. For this purpose, we aimed to compare the effects of intraarticular tramadol, magnesium, and ketamine with combinations of pericapsular bupivacaine on postoperative pain and recovery in arthroscopic meniscectomy. METHODS: Ninety patients who underwent arthroscopic meniscectomy were enrolled in the study. Group T was given tramadol, Group K was given ketamine, and Group M was given magnesium reconstituted intraarticularly, and all groups received periarticular bupivacaine. Comparisons were made in terms of the patients' postoperative Visual Analogue Scale scores with and without movement, need for additional analgesics, first analgesic time, mobilization times, adverse effects, and satisfaction with the analgesics. RESULTS: The Visual Analogue Scale scores were lowest in Group T at 0 minutes, and were higher in the 15th and 30th minutes and 1st, 2nd, and 6th hours. Visual Analogue Scale values with movement were found to be high in Group M at 0 and 15 minutes, but they were found to be higher in group T in the 30th minute, 1st, 2nd and 6th hour. The groups were similar in terms of postoperative additional analgesic use, number of analgesic use, and satisfaction with analgesics; however, the first analgesic time was earlier in Group M, and the first mobilization time was earlier in Group K. CONCLUSION: Intraarticular ketamine enables early mobilization and less need for additional analgesics, it also provides a better analgesic effect in comparison with intraarticular tramadol and magnesium.

Osteoid osteoma of the lunatum mimicking Kienböck's disease.

Hands, especially lunatum, are involved very rarely with osteoid osteoma. This report presents an osteoid osteoma of the lunatum, which was previously misdiagnosed as Kienböck's disease and had undergone surgery. Magnetic resonance imaging may lead the clinician to misdiagnose because of the excessive bone edema around the carpus. The operation should be planned according to radiography and computed tomography findings.

Wrist Tenosynovitis due to Mycobacterium bovis Infection: Case Series and Review of the Literature.

SUMMARY: Tuberculosis infections are still one of the most important public health problems among developing countries. Musculoskeletal involvement represents 10-15% of all extrapulmonary cases. Tuberculosis tenosynovitis is usually misdiagnosed as nonspecific tenosynovitis. To avoid misdiagnosis and mistreatment, it is important to be alert for mycobacterial infections. This article presents 3 patients with wrist tenosynovitis, which was caused by Mycobacterium bovis infection. The article also includes review of the literature.

The axillary sheath and single-injection axillary block.

Failure to block the terminal nerves of the brachial plexus, the circumferential type of incomplete axillary brachial plexus block, is the main problem of the single-injection technique. Two studies were carried out to observe the internal anatomy of the axillary sheath and the effect of different volumes of dye injected into the sheath in cadavers. In our first study, the internal arrangement of the axillary sheath and its septae were examined microscopically by slicing the sheath longitudinally and transversely. In the second study, boluses of 10, 20, and 40 cc of methylene-blue were injected into one of the compartments of the axillary sheath. The axillary sheath was dissected out and sliced transversely to observe the spread of the dye in the injected and in the adjacent compartments. The specimens of the axillary sheath were then opened longitudinally and the septae excised and examined at x10 magnification to see the effect of the various volumes of the injection bolus. This study shows that septae from the deep surface of the axillary sheath form compartments for each nerve. The septae function as barriers under physiologic conditions. By increasing the injected volume of solutions, bubble-like defects are produced in the septae in the compartments into which leakage was demonstrated.

An unusual supracondylar process syndrome.

We report a case of a supracondylar process that was located beneath the neurovascular bundle and caused tenting of the bundle with elbow extension and supination.

Spinoglenoid septum: a new anatomic finding.

The spinoglenoid ligament has been implicated in compression of the suprascapular nerve in cases with isolated atrophy of the infraspinatus muscle. We dissected 32 shoulders of 16 embalmed cadavers. We could detect a spinoglenoid ligament in only 5 shoulders, and it was thin, loose, and weak. Instead of the spinoglenoid ligament, we observed a septum formed by the thickening of the fascial cover of the distal third of the supraspinatus and infraspinatus muscles. It originated from the spinoglenoid notch and extended into the posterior capsule. We named this structure the spinoglenoid septum. The suprascapular nerve passed between the bony margin of the spinoglenoid notch and the medial concave margin of the spinoglenoid septum. This septum may be a cause of dynamic compression of the suprascapular nerve.
