  • Ulnar nerve compression in the cubital tunnel is a common entrapment syndrome of the upper limb. Pulsed radiofrequency lesioning (PRFL) has been reported as a treatment method for relieving neuropathic pain. Since the placement of the electrode in close proximity to a targeted nerve is very important for the success of PRFL, ultrasound seems to be well suited for this technique. A 36-year-old woman presented with complaints of numbness and pain on the medial aspect of the elbow and the pain radiated down to the $4^{th}$ and $5^{th}$ fingers for 10 years after she suffered an elbow contusion, we then scheduled this woman for the ultrasound guided PRFL of the ulanr nerve. The initial ultrasound examination demonstrated a swollen nerve, loss of the fascicular pattern and an increased cross sectional area of the ulnar nerve. After confirmation of the most swollen site of the nerve via ultrasound, two sessions of PRFL were performed. The postprocedural 10 cm visual analog scale score decreased from 8 to 1 after the two sessions of PRFL.

  • Clinodactyly is defined as an angulation of a digit in the radio-ulnar plane. This anomaly can be congenital, dominantly inherited, or acquired due to trauma or inflammation. Although the deformity usually causes little functional impairment, correction is made because of cosmetic problems. Male subject, with polydactyly on thumb(Wassel's type VII) received first surgery at the age of one. And at the age of six, abnormal growth on the radial side of the first metacarpal bone and ulnar deviation of the distal phalanx of the thumb at the interphalangeal joint had developed. The authors used the growing bony segment from the first metacarpal bone as a bone graft for the correction of clinodactyly on thumb. Z-plasty incision was made on the concave(ulnar) side of thumb and a wedge osteotomy was made on the distal phalanx. The bone graft was inserted into the gap of the distal phalanx of the thumb and fixed it with K-wires. Deformity of the metacarpal bone and clinodactyly on thumb was corrected effectively without donor site morbidity with noticible growth of the grafted metacarpal bone 12 months after surgery.

  • We report a case of a 69-year-old right-dominant man who had an open Monteggia-like lesion of the right elbow (Gustilo-Andersen IIIA) with severe proximal ulna bone loss associated with an ipsilateral ulnar shaft fracture due to a motorcycle accident. The patient underwent two-stage surgery. Wound debridement and bridging external fixation were performed at first. Three months later, a frozen massive osteochondral ulnar allograft was implanted and fixed with a locking compression plate. A superficial wound infection appeared 5 weeks after the second surgery. Superficial wound debridement, negative pressure therapy, and antibiotics were administered for 3 months, achieving infection healing. At 3 years post-surgery, the elbow range of motion was satisfactory with a Disabilities of the Arm, Shoulder and Hand (DASH) score of 16.7. Radiographs and computed tomography scans showed good allograft-bone integration without allograft reabsorption or hardware loosening. Although not complication-free, massive ulna osteochondral allograft implantation can be considered a valid option in cases of open Monteggia-like lesions associated with ulnar shaft fracture and severe bone loss in active patients, whenever osteosynthesis or joint replacement is not a proper solution. This type of bone stock restoration allows for future surgery, if needed.

  • Background: While initial reports of surgical repair are promising, literature detailing post-repair outcomes is lacking. This study explores the effectiveness of ulnar collateral ligament (UCL) repair in returning professional baseball players to their pre-injury level of play. Professional baseball players undergoing UCL repair will have successful outcomes and high return to sport rates after surgery. Methods: From 2016 to 2021, publicly available databases were utilized to search for professional baseball players who underwent UCL repair. Players were included if they underwent primary UCL repair with an internal brace. Players were excluded if they underwent revision UCL repair, UCL reconstruction, or were amateur baseball players. Results: Of the 11 pitchers that underwent UCL repair, MiLB pitchers returned to sport at an average of 17.5 months. MiLB pitchers had similar ERA, games played, innings pitched, and walks plus hits per inning pitched (WHIP) before and after surgery. Four MLB pitchers (80%) returned to sport at 9.55 months. MLB pitchers had fewer games played and innings pitched but similar ERA and WHIP in after versus before surgery. Pitch velocity and spin rates after surgery varied based on pitch type. The 7 positional players who underwent UCL repair showed no differences in batting or fielding performances before versus after surgery. Conclusions: UCL repair can successfully return both pitchers and positional players at both the MiLB and MLB level back to play at pre-injury levels. Repair can be considered as an option in the right type of injury for players hoping to maximize performance after surgery with minimal recovery time.

  • Objective: The objective of this study was to measure the upper-limb motions and postures of grapes-harvesting tasks using electrical goniometers and analyze the upper-limb motions in a kinematic way to assess the risk of musculoskeletal disorders. Background: Grapes farmers are exposed to various risk factors of musculoskeletal disorders (MSDs) such as repetitive upper-limb motions, non-neutral postures, and manual handling of heavy items. The farmers have to use scissors repetitively while harvesting grapes with their being arms elevated over the shoulder height, which presumed to increase the physical workload. It has been reported that the grapes farmers feel the harvesting task as the one of the hardest work in cultivating grapes. We tried measure the wrist and elbow angles while the farmers were carrying out harvesting tasks to understand how much workload the work impose on the farmers, which can be helpful in making interventions of preventing musculosksletal disorders among grapes farmers. Method: We measured joint angles at the right wrist and elbow with a wireless measuring system with two electrical goniometers from five grape farmers. The grapes-harvesting task was classified into 6 different subtasks: 1) searching, 2) picking, 3) cleaning, 4) carrying, 6) storing, and 7) miscellaneous tasks. The subtasks were compared by mean angles, 10%, 50%, and 90% APDF values of wrist flexion/extension, ulnar/radial deviation, and elbow flexion. Results: The Kruskal-Wallis tests showed that the 10th percentiles of APDF of ulnar/radial deviation and flexion/extension of the wrist significantly differs among subtasks (p<0.05). It was found that the farmers assumed more deviated wrist postures in the ulnar direction when they picking and adjusting the grapes. The use of scissors seemed to force the farmers to severely bend their wrist in the directions of ulnar deviation and flexion. The grapes-harvesting task showed similar wrist postures and motion with poultry deboning and milking tasks. Conclusion: The grapes harvesting tasks make the farmers take ulnar deviated and extended postures in the wrist. The use of scissors makes them take more severely deviated postures in the wrist. Safety guidelines including use of ergonomic scissors can be provided to the farmers to improve their work conditions. Application: The results of this study can be used as a basic data for the development of safety guidelines for agricultural work.

  • Elbow joint injuries during exercise mostly occur by repeated stress to the joint than direct trauma. A pitcher who uses his arm above his head is most likely to be injured. So learning the right way to exercise and gaining the strength by maturating the body are essential for diminishing the chance of injury. On lateral ulnar tendon injury, which is most commonly injured area on elbow joint, pitchers generally complain of pain in arm movement above head and reduction of velocity, accuracy, and number of pitching. When there is pain on upper arm in harsh using, the stress fracture must be thought and epicondylar physis fracture of medial arm can occur by repeated abduction stress and contraction of flexors on forearm on children with immature skeleton. Osteochondritis dissecans of capitullum occur in young athletes who use there upper limb continuously lifting weights and gym work. And stress of abduction-extension includes damage of soft tissue and bone components, post medial crush syndrome, lateral ulnar ligament injury, extensor-abductor injury, stress of radius- capitullum are in this category.

  • Eletrophysiological methods revealed subclinical neuropathy in 26 workers, exposed from 1 to 17 years to lead and whose blood lead (PbB) values had never exceeded $70{\mu}g/100\;ml$, as ascertained by checking the monitor reports of the factory and by careful exposure history. The PbB determinations had been tested repostedly and had been found valid. The main findings were slowing of the maximal motor conduction velocities of the median and ulnar nerves and particularly the conduction velocity of the slower fibers of the ulnar nerve. Eletrophysiological abnormalities comprised fibriliations, diminution of the number of motor units on maximal contraction, and an abnormal. Thus, a dose-response relationship exlets on a group basis. Since the regular monitoring of PbBs in most workers during their entire period of exposure excludes the possibility of a body burden out of proportion to the PbBs silght neuro-logical damage is produced at exposures hitherto regarded as quite sale.

  • A 1.4 kg adult great homed owl was presented to the University of Missouri-Columbia Veterinary Teaching Hospital after being found by the side of the highway. Physical examination revealed soft tissue injuries to the left wing and leg, and good body condition (body score 4/5). The radiographs revealed comminuted fracture of the diaphysis of the left tibiotarsus (severe) and ulna (mild). Closed reduction of the fracture was performed to the left tibiotarsus and ulna. System combining an intramedually (IM) Kirschner pin, IM Kirschner pin for external skeletal fixation, and polymethylmethacrylate was used for fracture repair. At 13 weeks, radiographs revealed that bridging callus was well formed over cortices of the fracture area. No physical, behavioral, or other assessable impairment was found during the rehabilitation period.

  • A 52-year-old female patient presented with an 8-year history of progressively intense pain, cold sensitivity, and severe tenderness to palpation of the ulnar side of the tip of her right little finger. Subsequent diagnostic evaluation with ultrasonographic imaging revealed the presence of a glomus tumor in the tender area. Glomus tumors are benign, occurring in the vascular hamartomatous tubercles of the glomus body, which is a myoarterial apparatus typically found in the reticular dermis of the skin. Distal glomus tumors are relatively uncommon, and account for approximately 1% of all hand tumors. Most of them are located in the subungual area because of its high concentration of glomus bodies. We report a case of a glomus tumor with a typical triad of symptoms, yet with a rare location : on the pulp of the ulnar aspect of the distal phalanx of the right little finger.
