Background: Tardy ulnar nerve palsy is the development of late onset ulnar nerve dysfunction and is usually treated by open anterior transposition of ulnar nerve. Open technique is done using a longitudinal incision about 6-8 inch. in length with chances of development of medial antebrachial cutaneous nerve neuromas., Purpose: In this study, we describe the technique of Endoscopic Anterior Transposition of Ulnar Nerve (EATUN procedure) to treat tardy ulnar nerve palsy and analyze the results., Methods: Seven patients diagnosed to have tardy ulnar nerve palsy was treated by EATUN. The humerus-elbow-wrist angle (HEW), pre- and post-operative intrinsic muscle power and sensory assessment, Dellon scores, and the Q-DASH was analyzed., Results: The minimum follow-up was 12 months (Mean 27.4 months, Range 12-36 months). Improvement in Dellon and Q-DASH scores following EATUN procedure was statistically significant. There was objective improvement of intrinsic muscle power and sensation on follow-up, though not statistically significant. No instance of neuroma of the medial cutaneous nerve of forearm was noted., Conclusions: The endoscopic anterior transposition of the ulnar nerve is a good option in surgical management of tardy ulnar nerve palsy., Level of Evidence: Therapeutic Level IV., Supplementary Information: The online version contains supplementary material available at 10.1007/s43465-021-00366-w., Competing Interests: Conflicts of interestThe authors declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article., (© Indian Orthopaedics Association 2021.)

Background: Many implants and techniques are used for the treatment of open phalangeal fractures with varying grades of stability. The ubiquitous and simple Kirschner (K) wiring does not provide adequate stability to allow early mobilization of fingers. Lister described a combination of coronal interosseous wire and oblique K-wire technique for phalangeal fracture fixation with a stable construct that allowed early mobilization. Due to the fancied resemblance of this construct to the Greek alphabet θ (theta), we have referred to this as the theta fixation., Materials and Methods: Ten patients with open proximal phalangeal shaft (transverse) fractures were treated with theta fixation between January and June 2010. Outcome was analysed in terms of stability, early mobilization, fracture healing and function of hand. They were graded according to the Belsky score., Results: 90% patients were graded excellent and 10% good, with none having fair or poor results. All fractures allowed the mobilization at a mean of 2.9 days and all healed at an average of 6.1 weeks. No loss of stability was seen on followup X-rays. All patients returned to their old profession., Conclusion: The theta fixation technique is a safe, simple and effective method for open transverse phalangeal fractures with results comparable to other techniques. This method gives superior fracture stability to allow early mobilization of joints and thus early return of function. It is also a cost effective way of management for the developing world.

Distal radioulnar joint is a trochoid joint relatively new in evolution. Along with proximal radioulnar joint, forearm bones and interosseous membrane, it allows pronosupination and load transmission across the wrist. Injuries around distal radioulnar joint are not uncommon, and are usually associated with distal radius fractures,fractures of the ulnar styloid and with the eponymous Galeazzi or Essex_Lopresti fractures. The injury can be purely involving the soft tissue especially the triangular fibrocartilage or the radioulnar ligaments. The patients usually present with ulnar sided wrist pain, features of instability, or restriction of rotation. Difficulty in carrying loads in the hand is a major constraint for these patients. Thorough clinical examination to localize point of tenderness and appropriate provocative tests help in diagnosis. Radiology and MRI are extremely useful, while arthroscopy is the gold standard for evaluation. The treatment protocols are continuously evolving and range from conservative, arthroscopic to open surgical methods. Isolated dislocation are uncommon. Basal fractures of the ulnar styloid tend to make the joint unstable and may require operative intervention. Chronic instability requires reconstruction of the stabilizing ligaments to avoid onset of arthritis. Prosthetic replacement in arthritis is gaining acceptance in the management of arthritis.
