PURPOSE: The second toe PIP joint free flap is a method of reconstruction used for abnormalities of the PIP joint of the finger. We report the results of the additional tenolysis in patients with a difference between passive ROM and active ROM after second toe PIP joint free flap. METHODS: From March 2001 to July 2008, tenolysis was performed in patients with a difference in their active and passive ROM after second toe PIP joint free transfer, performed on 14 fingers. We performed a retrospective analysis of the medical records, noting the clinical and radiological findings. In addition, we measured the preoperative and postoperative range of motion of the PIP joint. RESULTS: The average active ROM was 22.5degrees in three months after the joint transfer surgery, and was 38degrees after additional tenolysis from five months to twelve months after the joint transfer. CONCLUSIONS: Additional tenolysis, after the second toe PIP joint free flap, might be a good option with an improved results in patients with difference in active and passive ROM of a transferred PIP joint.

Ulna Nerve Compression Caused by a Tortuous Ulnar Artery

PURPOSE: This case report presents ulnar nerve compression which associated with variant distribution of ulnar artery at the proximal site of the wrist. MATERIALS AND METHODS: Based on the patient's symptoms, we could assume a neuropathy resulting from the compression of the ulnar nerve. The magnetic resonance imaging (MRI) was used to evaluate the anatomical abnormality of the ulnar artery at the site of compression, and the elecromyogram (EMG) and Nerve conduction velocity (NCV) were also performed to confirm the overall abnormality of the ulnar nerve. RESULTS: The tortuous ulnar artery of the lesion which was in the same course as that of ulnar nerve surrounded by sheath seemed to be compressed. Such finding was resolved 5 minutes after taking off tourniquet during adhesiolysis. Along with the improvement in the symptoms of paresthesia and the numbness of the patient a day after the surgery, the atrophy of the muscle and the weakness of the affected lesion were also slightly improved 6 months after the adhesiolysis. The decrease in abnormal spontaneous activity of the ulnar nerve was observed in both EMG and NCV, performed after the 6 month of the surgery. CONCLUSION: Among the patients manifesting significant symptoms of neuropathy arising from ulnar nerve compression, the tortuous ulnar artery as the source of entrapment of ulnar nerve was observed. Six months after the adhesiolysis of the sheath, the overall improvement of clinical symptoms was remarkable.
