Grip Force Measurement as a Complement to High-Resolution Ultrasound in the Diagnosis and Follow-Up of A2 and A4 Finger Pulley Injuries.

ABSTRACT: The ability of finger flexors to generate force has been studied in relation to climbing performance. However, not much attention has been paid to the decrease in finger grip force in relation to annular pulley injuries. The purpose of the present study was to determine if an injured annular pulley implies a finger flexor force decrease, as well as its relation to clinical and sonographic changes. We performed an observational study in 39 rock climbers with A2 or A4 pulley injuries to the 3rd or 4th fingers. The variables considered were pain upon palpation, ultrasound tendon-bone distance, and finger grip strength decrease. Three rock climbing grip types were considered: the one finger crimp, open crimp, and close crimp. Injured rock climbers presented a decrease in finger grip strength compared to non-injured controls when performing a one finger crimp (p < 0.001). There exists a significant correlation between a tendon-bone distance at the level of the injured pulley and a decreased finger grip strength measured by performing a one finger crimp (p = 0.006). A decrease in finger grip strength could be considered in the diagnostic and follow-up process of A2 and A4 pulley injuries to the 3rd and 4th fingers.

Project description:AIM:To investigate the effectiveness of ultrasound-guided release of the first annular pulley and compare results with the conventional open operative technique. METHODS:In this prospective randomized, single-center, clinical study, 32 patients with trigger finger or trigger thumb, grade II-IV according to Green classification system, were recruited. Two groups were formed; Group A (16 patients) was treated with an ultrasound-guided percutaneous release of the affected A1 pulley under local anesthesia. Group B (16 patients) underwent an open surgical release of the A1 pulley, through a 10-15 mm incision. Patients were assessed pre- and postoperatively (follow-up: 2, 4 and 12 wk) by physicians blinded to the procedures. Treatment of triggering (primary variable of interest) was expressed as the "success rate" per digit. The time for taking postoperative pain killers, range of motion recovery, QuickDASH test scores (Greek version), return to normal activities (including work), complications and cosmetic results were assessed. RESULTS:The success rate in group A was 93.75% (15/16) and in group B 100% (16/16). Mean times in group A patients were 3.5 d for taking pain killers, 4.1 d for returning to normal activities, and 7.2 and 3.9 d for complete extension and flexion recovery, respectively. Mean QuickDASH scores in group A were 45.5 preoperatively and, 7.5, 0.5 and 0 after 2, 4, and 12 wk postoperatively. Mean times in group B patients were 2.9 d for taking pain killers, 17.8 d for returning to normal activities, and 5.6 and 3 d for complete extension and flexion recovery. Mean QuickDASH scores in group B were 43.2 preoperatively and, 8.2, 1.3 and 0 after 2, 4, and 12 wk postoperatively. The cosmetic results found excellent or good in 87.5% (14/16) of group A patients, while in 56.25% (9/16) of group B patients were evaluated as fair or poor. CONCLUSION:Treatment of the trigger finger using ultrasonography resulted in fewer absence of work days, and better cosmetic results, in comparison with the open surgery technique. It is a promising method that represents excellent results without major complications, so that it could be possibly be established as a first-line treatment in the trigger finger's disease.

Project description:ContextThe medial head of the gastrocnemius is the third most commonly strained muscle in elite athletes after the biceps femoris and rectus femoris. The differential diagnosis of posterior calf injury includes musculoskeletal and nonmusculoskeletal causes. Classically, delineation of these injuries from one another relied primarily on historical features and physical examination findings. The utilization of musculoskeletal ultrasound (sonography) has augmented the diagnosis of these injuries by providing dynamic, real-time confirmation.Evidence acquisitionA review of PubMed, OVID, and MD Consult prior to January 2016 was performed using search terms, including s oleus ultrasound, gastrocnemius ultrasound, and tennis leg. The references of the pertinent articles were further reviewed for other relevant sources.Study designClinical review.Level of evidenceLevel 4.ResultsThere have been few reviews to date of calf injuries and the use of sonography in their diagnosis. Prompt diagnosis utilizing ultrasound allows the clinician to focus management on gastrocnemius injury if present. Two-thirds of calf injuries occur at the junction of the fascia between the medial head of the gastrocnemius and the soleus. Injuries to the lateral head of the gastrocnemius occur in up to 14% of patients in some case series, but injury may occur anywhere from the proximal origin to the mid-belly to the fascial junction with the soleus. Numerous injuries to the posterior compartment can mimic gastrocnemius strain, and musculoskeletal ultrasound can aide in their diagnosis by incorporating real-time imaging into the grading of the injury and visual confirmation of physical examination findings.ConclusionAcute injury to the posterior compartment of the lower extremity can represent a diagnostic challenge. Medial gastrocnemius strain represents the most common injury of the posterior compartment of the lower extremity. Ultrasound is a useful tool to assist the clinician in determining the specific cause of calf injury, estimate the severity of the injury, and monitor progress of healing. The vast majority of calf injuries can be diagnosed and managed without any additional imaging. Serial diagnostic ultrasound of an injured area allows for direct monitoring of tissue healing and may allow the clinician to more confidently assess response to treatment and help guide return-to-play decisions.
