PURPOSE: There is little information on solitary tumorous calcification causing carpal tunnel syndrome in the literature. This study describes our experience with surgically treated cases of solitary tumorous calcification causing carpal tunnel syndrome. METHODS: Seven patients with symptomatic carpal tunnel syndrome who had tumorous calcification in the carpal tunnel confirmed by radiographical examinations and had then undergone open incisional carpal tunnel release were reviewed. The precise location and the appearance of the calcified mass were confirmed with the preoperative radiographic examinations and the operative records. The additional histology and the composition analysis of the calcified mass were also reviewed in five removed calcifications. RESULTS: Radiographs of each hand revealed a mass of calcification lying anterior to the capitate bone in the carpal tunnel. Intraoperatively, an oval calcified nodule, measuring 10 x 10 x 10 - 18 mm, was observed overlying the capitate, attached firmly to the palmar radiocarpal extrinsic ligament. A composition with an average of 60 % basic calcium phosphate was revealed by infrared absorption spectrometry. Histological sections showed a calcified deposit surrounded by fibrocartilagenous tissue in three cases. CONCLUSION: These facts suggest that the pathogenesis of tumorous calcification causing carpal tunnel syndrome is comparable with that of calcifying tendinitis of the rotator cuff in which a cell-mediated reactive process plays an important role at the tendon insertion.

Sclerosing injections to treat midportion Achilles tendinosis: a randomised controlled study evaluating two different concentrations of Polidocanol.   Knee Surg Sports Traumatol Arthrosc.

Two to three ultrasound (US) and colour Doppler (CD)-guided injections of the sclerosing substance Polidocanol (5 mg/ml) have been demonstrated to give good clinical results in patients with chronic midportion Achilles tendinopathy. This study aimed to investigate if a higher concentration of Polidocanol (10 mg/ml) would lead to a less number of treatments, and lower volumes, needed for good clinical results. Fifty-two consecutive Achilles tendons (48 patients, mean age 49.6 years) with chronic ... [Abstract] [Full-text]

Elevation of systemic matrix metalloproteinase-2 and -7 and tissue inhibitor of metalloproteinases-2 in patients with a history of Achilles tendon rupture: pilot study.   Br J Sports Med.

OBJECTIVES: To compare serum levels of matrix metalloproteinases (MMPs) and tissue inhibitors of metalloproteinases (TIMPs) between patients with a history of Achilles tendon rupture and blood donor controls, and to relate MMPs and TIMPs to mechanical properties of the tendons during healing. METHODS: More than three years after injury, we measured serum levels of MMP-1, -2, -3, -7, -8, -9 and -13 and TIMP-1 and -2 in eight patients who had suffered Achilles tendon rupture. Twelve blood donors ... [Abstract] [Full-text]

Prospective study of refractory greater trochanter pain syndrome. MRI findings of gluteal tendon tears seen at surgery. Clinical and MRI results of tendon repair.   Joint Bone Spine, 75(4): 458-64.

OBJECTIVES: (1) To compare MRI and surgical findings in patients with refractory greater trochanter pain syndrome and (2) to assess surgical outcomes. METHODS: All consecutive patients seen between 2002 and 2006 by a single clinician were selected for surgical treatment according to the following criteria: (1) tendinopathy confirmed by physical tests; (2) painful disability persisting for at least 6 months despite treatment; (3) on MRI: area of high signal intensity on T2-weighted images, in ...

MRI findings in renal transplant recipients with hip and knee pain.   Eur J Radiol.

PURPOSE: To evaluate and demonstrate the MRI findings of renal transplant recipients with hip and knee pain and to investigate the most common etiology of pain. MATERIALS AND METHODS: 69 hip MRIs of 57 patients with hip pain and 30 knee MRIs of 24 patients with knee pain with no history of trauma were retrospectively evaluated by two radiologists. RESULTS: In the evaluation of hip MRIs, 24 patients had avascular necrosis and effusion, 2 patients had bone marrow edema consistent with early stage ... [Abstract] [Full-text]

Ironman triathletes: MRI assessment of the shoulder.   Skeletal Radiol, 37(8): 737-41.

OBJECTIVE: The objective of this paper was to demonstrate the prevalence of shoulder magnetic resonance imaging (MRI) abnormalities, including abnormal bone marrow signal at the acromioclavicular (AC) joint in symptomatic and asymptomatic Ironman Triathletes. MATERIALS AND METHODS: The shoulders of 23 Ironman Triathletes, seven asymptomatic (group I) and 16 symptomatic (group II), were studied by MRI. A separate, non-triathlete group was evaluated specifically for AC joint marrow signal ... [Abstract] [Full-text]

Long-term Results of Lateral Calcaneal Artery Flap for Hindfoot Reconstruction.   J Reconstr Microsurg, 24(4): 239-45.

The purpose of the present study was to analyze our long-term results of lateral calcaneal artery flap transfer for hindfoot reconstruction. A total of four patients (average age, 48 years) underwent lateral calcaneal artery flap transfer. The etiologies were heat injury of the lateral malleolus in one patient and skin necrosis over the Achilles tendon attachment site in three patients due to displaced calcaneal fracture, pyogenic tendinitis of the Achilles tendon, and vascular insufficiency of ...

Achilles Tendon Doppler Flow May Be Associated With Mechanical Load Among Active Athletes.   Am J Sports Med.

BACKGROUND: Tendon Doppler flow may be associated with tendon pain in symptomatic patients, but the relationship between Doppler flow and pain among athletes who are still competing is unclear. HYPOTHESIS: Among active athletes, Doppler flow may partly reflect tendon adaptation to increased mechanical load and/or asymptomatic tendinopathy. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: The Achilles tendons of 61 badminton players (24 elite, 37 recreational) were examined ... [Abstract] [Full-text]

Differential Forces Within the Proximal Patellar Tendon as an Explanation for the Characteristic Lesion of Patellar Tendinopathy: An In Vivo Descriptive Experimental Study.   Am J Sports Med.

BACKGROUND: Patellar tendinopathy is a common condition affecting the posterior region of the proximal patellar tendon, but the reason for this typical location remains unclear. HYPOTHESIS: The posterior region of the proximal patellar tendon is subjected to greater tendinous forces than is the corresponding anterior region. STUDY DESIGN: Descriptive laboratory study. METHOD: An optic fiber technique was used to detect forces in both the anterior and the posterior regions of the proximal ... [Abstract] [Full-text]
