Bone marrow aspirate concentrate and matrix-induced chondrogenesis (BMIC) is an interesting treatment option for osteochondral lesions of the talus with promising short- to mid-term results. The various terminologies used to describe this surgical method need to be addressed. These include bone marrow-derived cell transplantation, matrix-induced bone marrow aspirate concentrate, and matrix-associated stem cell transplantation. BMIC is a one-stage, minimally invasive surgery performed arthroscopically or using a mini-open arthrotomy approach without a malleolar osteotomy in most cases. The lesion is replaced with hyaline-like cartilage, and treatment-related complications are rare. BMIC is a safe and effective treatment option and should be considered in large lesions or lesions with a prior treatment history. [ABSTRACT FROM AUTHOR]

Purpose: This study aimed to evaluate the relation between the degree of wrist joint distraction and postoperative restoration of joint function after performed external fixation with distraction of wrist joint in distal radius fracture. Methods: This study was conducted retrospectively on 55 patients who underwent reduction using external fixation for distal intra-articular radius fracture from January 2007 to December 2014. The degree of pre- and post-operative distraction was measured radiographically using the carpal height ratio (CHR). For postoperative functional assessment, range of motion of the wrist, Gartland Werley classification, grip strength, and pinch strength were measured. Results: In the functional assessment based on the Gartland Werley classification, excellent was reported by 31 patients, good; 16 patients, fair; 8 patients, and poor; 0 patients. The mean CHR was 0.519 preoperatively and 0.565 immediately after surgery. The mean postoperative CHR of excellent group was 0.581, demonstrating better clinical outcome in distraction than other groups. Eight case of joint stiffness was manifested when CHR value was lower than 0.54 and only 1 case of joint stiffness was manifested when CHR value was higher than 0.54, showing a tendency for lower incidence of joint stiffness when distracted over 0.54 of CHR. Conclusion: External fixation after sufficient distraction of the wrist joint produced an excellent outcome in the functional assessment. The better the prognosis in the Gartland Werley classification, the higher the CHR and the group with a CHR greater than 0.54 immediately after surgery showed less joint stiffness than the lower group.
