A new nerve transfer option of using viable fascicle of the ipsilateral middle trunk for suprascapular nerve reconstruction is presented. The procedure was used in two patients with upper brachial plexus injury involving loss of shoulder abduction and external rotation. Clinical evaluation and nerve conduction studies in both patients confirmed axonopathy of C5, C6 roots and C5 root, respectively. The proximal root stumps were unavailable for nerve grafting due to a very proximal root level scarring. The middle trunk fascicle was dissected on its superior surface and transferred to the non-functional suprascapular nerve. After 24 months follow up full abduction and external rotation could be achieved in both the patients. It is a simple and easy option for transfer to a suprascapular nerve in upper brachial plexus injuries. It lies next only to the upper trunk and does not require any additional dissection time. Donor deficit was not observed in our two patients.Chronic embedded-ring injury is a rare and uncommon presentation. This is also known as "chronic ring erosion" or "embedded ring syndrome" in the literature. Injury of this type has been associated with psychological impairment causing neglect of such injury. We herein describe a case of double embedded rings on the right ring finger in a 30-year-old healthy construction worker. A primary amputation at the metacarpophalangeal joint was performed in view of the chronicity of his condition and associated neurovascular damage. Early removal of ring is of paramount importance in any ring-associated injuries. However, fear of losing a digit has been the reason of delay in seeking medical treatment, which in turn ended up in dire consequences.Background Although postoperative outcomes of olecranon fractures are relatively favorable, postoperative stiffness of the elbow joint occurs occasionally. We aimed to identify negative prognostic factors for unfavorable outcomes following olecranon fractures. Methods We retrospectively reviewed the records of 100 patients with olecranon fractures and collected data on the conducted procedures, age, fracture condition, postoperative reduced position, and postoperative active range of motion (AROM) of the elbow joint. The primary outcome was the regaining of an AROM of > 130° flexion and less then -30° extension of the elbow joint at the final follow-up. We performed multivariate logistic regression analysis to identify the negative prognostic factors. Results The mean follow-up period was 11 months. All patients regained an average AROM of 121 degrees. Eighty-one patients regained a favorable AROM of the elbow joint. On univariate logistic regression analysis, diabetes mellitus (OR, 8.2; 95%CI, 1.6-41.7), cn the postoperative AROM of the elbow joint, at least not in the early postoperative period.Background Despite the movement of the thumb carpometacarpal joint has been studied, many unclarified points remain regarding the movement of this joint. The purpose of this study was to evaluate the in vivo kinematics of the thumb carpometacarpal joint during flexion and abduction using computed tomography images. Methods The subjects were 9 healthy males. Computed tomography images were obtained in 4 equally-divided positions from maximum extension to maximum flexion, and maximum adduction to maximum abduction of the thumb. A three-dimensional model was constructed from these images, and the models of each position were superimposed with reference to the trapezium. The amount of angular change around the bone axes of first metacarpal bone and rotation axes were evaluated. Results We found that the first metacarpal bone showed relatively simple behavior during abduction. However, during flexion, it exhibited a particular movement in which the amount of angular change of the metacarpal bone with respect to the trapezium rapidly increased with deep flexion. Conclusions These results suggest that the thumb carpometacarpal joint exhibits a sp
