Intermittent occlusion of the ulnar artery developed in a patient causing cramp in her right hand. Both flexion and extension of the wrist completely obstructed bloodflow in the ulnar artery, a level just proximal to the wrist. At operation, a tight hand of antebrachial fascia was found to the cause of this intermittent arterial occlusion. Surgical release of this fascial ban reduced complete relief of her symptoms.

Abstract We present a case of dialysis associated steal syndrome in a hemodialysis patient with left radiocephalic arteriovenous fistula that caused him severe rest pain. Angiography showed retrograde flow from the ulnar artery to the distal radial artery through a hypertrophied palmar arch. The problem was solved by surgical ligation of the distal radial artery leading to complete relief of patient symptoms without any notable complications.

We compared the clinical outcomes of patients who underwent coronary artery intervention by the transulnar and transradial artery approaches. In this 1 year, single-center study, patients were randomized to either a radial artery (RA) or ulnar artery (UA) group. Of 538 patients, the primary outcome, arterial occlusion of a forearm artery, occurred in 21 of 225 patients in the RA group compared to 6 of 220 patients in the UA group (9.3% vs 2.7%, P = .007). The rate of arterial occlusion was significantly lower following ulnar access compared to radial (odds ratio [OR] = 3.85, P = .006). A higher risk of occlusion was associated with repeated procedures rather than a single procedure (OR = 5.14, P = .003), smoking (OR = 2.39, P = .04), and arterial to sheath diameter ratio of ≤1 (OR = 2.62, P = .03). However, the disadvantage of UA was an increase of incidence of hematomas (13.2% vs 5.8%, P = .01) and symptoms of discomfort (15.5% vs 5.8%, P = .002). In conclusion, the transulnar strategy proved to be noninferior to the transradial approach for coronary procedures ( ClinicalTrials.gov Identifier: NCT01979627).

Nineteen patients underwent surgical synovectomy and debridement for the clinical diagnosis of stage I posterior tibial tendon (PTT) dysfunction. Stage I PTT dysfunction is characterized by pain and swelling along the medial aspect of the ankle. Fourteen patients (74%) reported complete relief of pain, 3 patients (16%) reported minor pain, and 1 patient (5%) had moderate pain, and 1 (5%) had continued severe pain. Sixteen (84%) of the patients subjectively reported being “much better” and had a return of function of the PTT, as evidenced by their ability to perform a single limb-heel-rise test. Two patients (10%) underwent subtalar arthrodesis for progressive foot deformity and continued pain. Based on these results, surgical release, tenosynovectomy, and debridement are recommended for the treatment of stage I PTT dysfunction.

This study quantifies the effect of a simultaneous grip on wrist strength. It was hypothesized that wrist flexion strength increases with an increasing grip and wrist extension strength decreases with an increasing grip. Twelve subjects performed maximum wrist flexion and extension exertions with a different level of simultaneous grip – minimum, preferred, and maximum. Wrist flexion strength increased 34% and wrist extension strength decreased 10% from minimum to maximum grip. This shows that measure of wrist strength for assessing strength capabilities or the efficacy of hand surgeries or rehabilitation programs requires control of finger flexor activities to ensure consistent and relevant results. When opening a bottle in an outward direction (right hand thread), wrist extension strength may be significantly limited by a simultaneous grip due to muscle antagonism. When twisting a fragile or uncomfortable object, reduced finger flexor activities can limit wrist flexion strength.

The transulnar approach (TUA) has been considered both as primary access and as a secondary access site after transradial access (TRA) failure for coronary invasive procedures. However, there is little evidence supporting the use of the TUA as the first approach to diagnostic coronary angiography (CAG) or interventions. Patients (n = 587) who underwent CAG and/or angioplasty (292 patients via TRA, 295 patients via TUA) were included. The primary end points of the study were major adverse cardiac events and major vascular events (hematoma, vascular occlusion, vasospasm), and secondary end points included angiographic success, crossover rate, and angiographic procedural times. The mean age was 60 ± 21 years. The composite primary end points occurred in 34 (11.6%) patients in the TRA and 22 (7.4%) patients in the TUA arm ( P < .001). More arterial occlusion and more arterial spasm than in the TUA and similar urgent target vessel revascularization were observed in the TRA group in 48 hours. Based on previous studies and our clinical experience, we speculated that the TUA performed by an experienced operator has equal status with the TRA for coronary catheterization, especially in patients with a palpable ulnar pulse.

Abstract Background Volar finger defects where critical structures exposed are always challenging for plastic surgeons. In these types of defects, local flaps, cross finger flaps, abdominal flaps, and free flaps are used. Free dorsoulnar artery perforator (DUAP) flaps and superficial palmar branch of radial artery (SPBRA) flaps are also used. In this case, we present a patient who was scheduled to receive a DUAP flap to address defect on the second finger of right hand; however, we repaired the defect with a SPBRA flap because intraoperative absence of the ulnar artery was observed. Materials and Methods A 34-year-old male patient was admitted with a wound that exposed the tendon and neurovascular bundle on the volar side of the second finger of the right hand. A free DUAP flap was planned for the patient. A perforator was detected during the preoperative Doppler ultrasound examination. While dissecting the perforator, we noted the absence of an ulnar artery proximal to the perforator vessel. The elevated SPBRA flap from same extremity and the defect were closed. Results Postoperative computer tomography showed an absence of the ulnar artery distal to the right antecubital region. No complications were seen in the donor and recipient areas. Long-term motor movements were natural, and the patient's quality of life was good. Conclusion Determining the perforator site using Doppler alone may not be sufficient in preoperative evaluation of patients scheduled to receive DUAP flaps. Performing an Allen test and using advanced imaging methods can prevent surgeons from encountering a bad surprise.

Arteriography of an adult manual labourer presenting with numbness and cold intolerance in the middle and ring fingers of the right hand demonstrated filling defects in the digital arteries of these two fingers associated with a corkscrew-like configuration of the ulnar artery in Guyon’s canal. This arterial segment was subsequently excised revealing intramural necrosis and fibrosis and non-occlusive intraluminal thrombosis. An arteriogram performed 2 years previously for an unrelated condition revealed a similar but less pronounced corkscrew configuration of the artery, suggesting that this finding could be a marker for arterial injury which may eventually lead to embolization or thrombosis with accompanying ischaemic symptoms.

1. Two rhesus monkeys were trained to perform flexion and extension movements of each digit of the right hand and of the wrist. Movements of all five digits and the wrist were monitored simultaneously. During each instructed movement, the instructed digit (or wrist) had the greatest excursion; other, noninstructed digits moved to varying degrees. 2. To assess the degree of independence of the different digits during these movements, I plotted, as a function of the instructed digit's position, the position of each noninstructed digit. The resulting trajectories typically were linear, with consistent slopes from trial to trial. 3. The slopes of these noninstructed digit versus instructed digit trajectories were used to calculate an individuation index for each instructed movement and a stationarity index for each digit. These indexes quantified two different aspects of independence. The individuation index reflects the degree to which other digits remained still during instructed movement of a given digit. The stationarity index reflects the degree to which a given digit remained still whenever it was a noninstructed digit. 4. In accordance with casual observation, thumb flexion and wrist flexion and extension consistently had both high individuation and stationarity and therefore can be said to be independent of the fingers. Although the same cannot be said of the other fingers, the present analysis provides a means of quantifying the degree of independence of these digits as well. 5. Factors are discussed that might contribute to the motion of noninstructed digits and to the trajectory linearity.

In certain occupations, injuries and microtrauma are commonly encountered by the soft tissues of the hand in the adult population, which may, however, less frequently lead to arterial occlusion. One such example is that of the Hypothenar Hammer Syndrome (HHS). It is a rare traumatic disease of the hand, caused by blunt traumas to the heel of the hand that may damage the ulnar artery at the level of hypothenar eminence. This results in occlusion or aneurysm of the vessel. It is of clinical importance due to the risk of loss of limb function following digital ischemia. The ulnar nerve barely gets compressed in the Guyon’s canal, which may in turn cause Guyon’s canal syndrome. This is a case of a 43-year-old male patient who presented with painful swelling of the right hand, which was diagnosed as a bizarre presentation of a bilobed and partially thrombosed pseudoaneurysm of the ulnar artery producing Guyon’s canal syndrome that had to be surgically excised. The objective of this case is to highlight the clinical presentation of HHS for early diagnosis and treatment.

This paper presents the elbow flexion and extension rehabilitation exercise system using marker-less Kinect-based method. The proposed exercise system is developed for the upper limb rehabilitation application that utilizes a low cost depth sensor. In this study, the Kinect skeleton tracking method is used to detect and track the joints of upper limb and then measure the angle of the elbow joint. The users perform the exercise in front of the Kinect sensor and the computer monitor. At the same time, they can see the results that displayed on the screen in real-time. The measurement of elbow joint angles are recorded automatically and has been compared to the reference values for the analysis and validation. These reference values are obtained from the normal range of motion (ROM) of the elbow. The results show the average flexion angle of the elbow joint that achieved by the normal user is 139.1° for the right hand and 139.2° for the left hand. Meanwhile, the average extension angle is 1.72° for the right hand and 2.0° for the left. These measurements are almost similar to the standard range of motion (ROM) reference values. The skeleton tracking works well and able to follow the movement of the upper arm and forearm in real-time.
