Is it possible to decrease skin temperature with ice packs under casts and bandages? A cross-sectional, randomized trial on normal and swollen ankles.

INTRODUCTION: There is a general belief that the presence of a cast or a bandage eliminates the lowering effects of skin temperature when local cold therapy applied on the surface of the cast or bandage. The purpose of this study is to determine the magnitude of temperature changes at the skin of the ankle after the application of frozen ice packs to the surface of various casts and bandages both in normal and swollen ankles. MATERIALS AND METHODS: Thirty-two healthy subjects (Group A) and 12 patients with Grade III inversion type acute ankle sprain (Group B) were randomly divided into four groups. The sensor of the digital thermometer was secured to the ankle over the anterior talo-fibular ligament in every subject before placement of a bandage or cast. Robert Jones bandage, elastic support bandage, a below-knee plaster cast and synthetic below-knee cast were applied in groups 1, 2, 3 and 4, respectively. Two frozen ice packs were placed around the cast or bandage at the level of sensor, and skin temperatures were recorded. RESULTS: The skin temperature under dressings and casts decreased significantly relative to the baseline temperatures with local cold therapy in all groups. The fall in the temperature with cryotherapy in group A showed a three-phase pattern of change between groups 1 and 2, groups 2 and 3 and groups 2 and 4 during the experiment. The fall in the skin temperature with ice packs differed significantly between groups 1 and 3, and also groups 1 and 4 from the beginning till the end of the experiment. There was no significant difference between groups 3 and 4 in terms of skin temperature fall with cryotherapy during the whole experiment. The results were similar in group B. CONCLUSION: A bandage or cast does not prevent measurable skin temperature lowering by frozen ice packs both in normal and swollen ankles.

Synovial hemangiohamartomas of the knee joint.

Hemangioma or vascular malformation of the synovium is rare and presents a difficult problem in diagnosis and treatment. A long history of joint pain and recurrent non-traumatic hemarthrosis usually draws attention to the hemangioma of the knee joint. The lesion can be seen in two different formations; the synovial hemangioma or the arteriovenous malformation named as hemangiohamartomas, both of which involve the synovium and cause non-traumatic episodes of hemarthrosis. MRI scanning together with arthroscopy is a diagnostic tool to demonstrate the extent and the nature of the lesion. We treated the three patients at different ages. All patients underwent standard radiographic examination, CT scans, MRI and diagnostic arthroscopy. After frozen section taken via arthroscopically, the lesions were excised by arthrotomy. The mean follow-up was 38 months (31-45) and all patients are asymptomatic postoperatively. Three additional cases and a review of the literature are presented because of the rarity of the lesion.

An unusual rotational injury: Pantibial ligamentous injury.

Pantibial ligamentous injury including knee dislocation and tibiotalar joint subluxation is an uncommon severe rotational injury. A 21-year-old male injured his right knee falling from a motorcycle. Physical examination revealed effusion on the right knee and ankle, and posterior translation of the tibia as well. The MRI of the right knee and ankle demonstrated the following findings: a complete disruption of cruciate ligaments, the medial collateral ligament, posteromedial corner injury together with a peripheric tear in the medial meniscus, the ruptured deltoid ligament, ankle syndesmosis space widening (>5 mm) and lateral subluxation of talus. Deltoid ligament of the right ankle was repaired and ankle syndesmosis was fixed with a cortical screw. The PCL and ACL were reconstructed arthroscopically with autogeneous bone-patellar tendon-bone graft. The midsubstance tear of MCL, posteromedial corner and medial meniscus tear were primarily repaired with nonabsorbable sutures. 3 years after the surgery, the patient was called for the final examination. MRI and X-ray findings of the knee and ankle joint demonstrated the continuity of ACL, PCL, MCL, and deltoid ligament. The patient, who is a farmer, can go back to his job and perform his daily activities. We presented a previously unreported case that involves both simultaneous occurrence of knee dislocation and tibiotalar joint subluxation. We used the term "Pantibial ligamentous injury" for this case.

The incidence and location of corona mortis: a study on 75 cadavers.

We dissected 150 fresh cadaver halves by ilioinguinal exposure, and counted all vessels more than 2 mm in diameter, connecting the obturator system to the external iliac system. The distance between the symphysis pubis and the anastomotic vessels was measured. We found vascular anastomoses between the obturator and external iliac systems in 91 of 150 sides (61%), and anastomotic veins in 78 of 150 exposures (52%). Arterial connections were seen in 29 of the exposures (19%). The mean distance between the anastomotic arteries and the symphysis pubis was 64 (45-90) mm, and 56 (37-80) mm for the communicating veins. There seemed to be no significant difference between genders in the incidence of corona mortis and the distance between communicating vessels and the symphysis pubis.
