Calcific tendinitis usually occurs within the area where tendon inserts to bone. In the shoulder joints, most cases occur within the supraspinatus tendon just proximal to the greater tuberosity. We report a rare case of calcific tendinitis occurred within the conjoined tendon of coracobrachialis and short head of biceps brachii in a patient with rheumatoid arthritis, diagnosed by means of ultrasonographic evaluation.

Purpose: The harvest of hamstring tendon is technically demanding because of the inadequate identification of hamstring tendon separation and accessory tendon of semitendinosus tendon. We conducted therefore conducted an anatomic study, aiming at the anatomic knowledge for graft harvest. Materials and Methods: 20 human cadaveric knees (10 cadavers) were used for the study. The location of tendon separation in conjoined tendon and accessory tendon of semitendinosus tendon were described and recorded. Results: The location of tendon separation of conjoined tendon was average $39.68{\pm}9.97mm$ vertically and $18.57{\pm}2.91mm$ horizontally from the tibial spine. We found that the accessory structure of the semitendinosus tendon was mostly fascia-like structure(17 knees), the tendinous structure, 3 cases which was straightly located 15cm from the tibial crest. Conclusion: We propose that the expected incision for hamstring tendon harvest is centered on the inferior 40mm, medial 20mm from the tibial spine. The accessory structure of the semitendinosus tendon was mostly found of fascia-like structure.

Fibroma of the tendon sheath (FTS) was initially described in 1936 by Geschickter and Copeland as a benign firmed soft tissue tumor that is rare and less common than another soft tissue tumors, especially giant cell tumors (GCT) of the tendon sheath. The common distinct feature is a slow-growing least painful rare entity arising from the tendon or tendon sheath. FTS is detected mostly in the fingers, hands and wrists but less commonly in the foot. Very few cases of FTS have been described arising from a flexor tendon of the foot. This article describes a 51-year-old patient with FTS that developed in the extensor tendon of the foot, which is the only known FTS to form in this area. Heterogeneous low signal intensity in both the T1- and T2-weighted images was observed in magnetic resonance imaging. The lesion was excised completely by open surgery. Histologically, it showed randomly arranged, fibroblast-like spindle cells in dense fibrous tissue and had insufficient hemosiderin-laden macrophages that are typical for GCT.

Purpose : The biceps femoris tendon (BFT) and lateral collateral ligament (LCL) in the knee were formerly known to form a conjoined tendon at the fibular attachment site. However, the BFT and LCL are attached into the fibular head in various patterns. We classified insertion patterns of the BFT and LCL using MR imaging, and analyzed whether the LCL attaches to the fibular head or not. Materials and Methods: A total of 494 consecutive knee MRIs of 470 patients taken between July 2012 and December 2012 were retrospectively reviewed. There were 224 males and 246 females, and patient age varied from 10 to 88 (mean, 48.6). The exclusion criteria were previous surgery and poor image quality. Using 3T fat-suppressed proton density-weighted axial images, the fibular insertion patterns of the BFT and LCL were classified into following types: type I (the LCL passes between the anterior arm and direct arm of the BFT's long head), type II (the LCL joins with anterior arm of the long head of the BFT), type III (the BFT and LCL join to form a conjoined tendon), type IV (the LCL passes laterally around the anterior margin of the BFT), and type V (the LCL passes posteriorly to the direct arm of the BFT's long head). Results: Among the 494 cases of the knee MRI, there were 433 (87.65%) type I cases, 21 (4.25%) type II cases, 2 (0.4%) type III cases, 16 (3.23%) type IV cases, and 22 (4.45%) type V cases. There were 26 cases (5.26%) in which the LCL and BFT were not attached into the fibular head. Conclusion: The fibular attachment pattern of the BFT and LCL shows diverse types in MR imaging. The LCL does not adhere to the head in some patients.
