PROMIS Measures in Patients with Ganglion Cysts: Who Chooses Surgical Excision Over Non-Operative Management?

Background: Ganglion cysts are common soft tissue masses of the hand and wrist. It is unclear why some patients pursue surgical excision and others do not. The objective of this study is to compare Patient-Reported Outcomes Measurement Information Systems (PROMIS) scores between patients with ganglion cysts undergoing surgical versus non-surgical treatment. Methods: Patients presenting to a tertiary, academic hand clinic diagnosed with a wrist ganglion cyst, based on clinical exam, were identified. PROMIS Physical Function (PF), Pain Interference (PI), and Depression scores at the time of diagnosis were reviewed. Data were then stratified according to surgical or non-surgical intervention, with subgroup analysis of dorsal versus volar ganglions and patients that chose to trial cyst aspiration. All results were compared utilizing the appropriate statistical methods. Results: Of 757 ganglion cyst patients, 264 underwent surgical excision and 493 were treated non-surgically. No difference was noted in PROMIS PF or Depression scores. However, the surgical cohort reported significantly increased preoperative PI scores (Table 2). A higher percentage of patients treated non-surgically received an aspiration attempt compared to those who ultimately received surgery (Table 3). Finally, patients with volar ganglion cysts had significantly increased PI and depression scores, as well as lower PF scores (Table 4). Conclusions: Presenting PROMIS PI may indicate an increased tendency to pursue surgical treatments and aid in the identification of ganglion cyst patients who are more likely to pursue surgical excision. Further research should focus on correlating absolute differences in PROMIS values with clinical significance.

Biomechanical Stability of Volar Plate Only Versus Addition of Dorsal Ulnar Pin Plate: A Dorsal Ulnar Fragment, C-3-Type, Distal Radius, Cadaver Fracture Model.

OBJECTIVE: To determine if the addition of a dorsal ulnar pin plate provides improved stability characteristics in the management of intra-articular distal radius fractures with an associated dorsal ulnar fragment. METHODS: OTA/AO type C3 fractures, with a dorsal ulnar fragment of one-third or one-half the width of the distal radius, were simulated in 9 matched pairs of fresh-frozen cadaveric arms randomized between fixed-angle volar plate only versus volar plate with addition of a dorsal ulnar pin plate. Prepared specimens were mounted in a custom load frame and loaded in extension with stepwise cyclic load increase. Dorsal plane interfragmentary displacements were compared between the 2 fixation constructs at 50-N and 100-N cyclic load. RESULTS: The addition of the dorsal ulnar pin plate significantly reduced interfragmentary displacements for the dorsal ulnar fragment at the 50 N load application, resulting in mean interfragmentary displacements of -0.1 ± 0.2 mm in comparison to -0.3 ± 0.2 mm with the volar plate-only construct. No other interfragmentary displacement comparisons were significant. No differences were found comparing the one-third and one-half size fragments. CONCLUSIONS: The addition of a dorsal ulnar pin plate improved stability characteristics with respect to the dorsal ulnar fragment. CLINICAL RELEVANCE: The addition of the dorsal ulnar pin plate, although statistically significant, improved displacement by less than 0.3 mm on average and thus may not prove to be important in clinical scenarios.

Hand and Wrist Tendinopathies.

Tendinopathies in the hand and wrist are common in athletes. This article reviews some of the common hand and wrist conditions, such as trigger digits, first dorsal compartment tendonitis, and extensor carpi ulnaris tendonitis. In addition, it reviews less commonly seen tendon conditions of the flexor carpi radialis and ulnaris, intersection syndrome, and extensor pollicis entrapment conditions. Diagnosis, nonoperative and operative treatment, and postoperative recommendations and return to play are also discussed.

Intraoperative Subluxation of the Ulnar Nerve: Use of a Triceps Sling Reconstruction Technique.

PURPOSE: To determine whether the triceps sling reconstruction technique is a safe and effective treatment of intraoperative ulnar nerve subluxation after in situ decompression. METHODS: Twelve patients who underwent a triceps sling reconstruction for intraoperative ulnar nerve subluxation after in situ release were retrospectively reviewed. The triceps sling technique consists of harvesting a small, distally based strip of triceps tendon and suturing the proximal end of the strip to the posterior aspect of the released Osborne ligament. Thus, a sling is created between the medial epicondyle and the olecranon, preventing the nerve from subluxating. Patients were clinically evaluated before and after surgery. Visual analog scale pain scores, static 2-point discrimination, strength, and Disabilities of the Arm, Shoulder, and Hand score were assessed. RESULTS: At a mean follow-up of 31 months (range, 24-38 months), there was a significant improvement in mean visual analog pain scores from 8.6 to 0.2. Static 2-point discrimination was improved from a mean of 9.1 mm before surgery to 5.7 mm afterward. Strength improved by a mean of 33% and 30% with grip and pinch, respectively. Mean Disabilities of the Arm, Shoulder, and Hand score improved from 45.9 to 3.7. No subluxation of the ulnar nerve was noted after surgery. No other complications were noted. No reoperations were required during the follow-up period. CONCLUSIONS: Triceps sling reconstruction is a safe treatment in patients with intraoperative ulnar nerve subluxation after in situ decompression. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Surgical Efficiency of Anterior Cruciate Ligament Reconstruction in Outpatient Surgical Center Versus Hospital Operating Room.

Anterior cruciate ligament (ACL) reconstructions are complex orthopedic procedures in which a proficient team is of vital importance. Outpatient surgical centers (OSCs) often provide orthopedic-specific teams; however, hospital operating rooms (ORs) commonly rotate staff. The purpose of this study was to compare the efficiency of pediatric ACL reconstructions between a surgical center and a hospital OR owned and directed by a single institution. Cases examined involved pediatric patients, aged 12 to 18 years (mean age, 15.9±1.5 years), who underwent ACL reconstructions by a single orthopedic surgeon from 2009 to 2014. Procedural efficiency was defined as shorter total OR time, less total staff, and fewer support staff changes. Total OR time was also broken into 3 distinct time periods: in-room to incision time, total procedure time, and stop time to out-of-room time. A total of 49 ACL reconstructions were performed in healthy athletes, with 28 surgeries at the OSC (mean age, 15.7±1.3 years) and 21 surgeries in the hospital OR (mean age, 16.1±1.8 years). Overall efficiency was higher at the OSC, with total OR time improved by 30 minutes on average (P=.0001) with less total staff (P=.0002). Surgical technician and nursing changes occurred 6 and 2.5 times more often in the hospital OR, respectively. Procedural efficiency was greater at the OSC. The provision of consistent and experienced orthopedicspecific teams allows for improvement in OR efficiency, cost, and value. [Orthopedics. 2017; 40(5):297-302.].
