ABSTRACT
Symptomatic bowstringing of digital flexor tendons is a rare complication of carpal tunnel release (CTR). Two weeks after open CTR, a 47-year-old man with severe carpal tunnel syndrome had relief of his preoperative median paresthesia but complained of new-onset painful snapping of the wrist and transient ulnar paresthesia occurring with wrist dorsiflexion and concomitant digital flexion. Physical examination localized the audible snapping to the hook of hamate (HOH) where manual pressure eliminated the wrist motion-induced snapping and the associated ulnar paresthesia. Wrist radiographs showed stage III scapholunate advanced collapse (SLAC) with marked palmar subluxation of the lunate. Wrist magnetic resonance imaging revealed palmar and ulnar subluxation of the digital flexors over the HOH due to the mass effect of the palmarly displaced lunate and the chronic carpal malalignment. The snapping wrist and accompanying ulnar paresthesia resolved after HOH excision, and no additional treatment for the asymptomatic SLAC wrist deformity was required. Satisfactory clinical outcome was observed at 5-year follow-up.
ABSTRACT
A nationally ranked Division One female collegiate tennis player presented with pain in the chest and right posterior rib region after feeling a popping sensation during a routine overhead movement. The patient was eventually diagnosed with 2 lower rib stress fractures. After unsuccessful conservative management, the player underwent an open reduction and internal fixation and autologous bone grafting of the sixth and seventh ribs with a muscle-sparing approach and was able to return to full competition. We present this case along with a systematic review of the literature regarding rib stress fractures, which included 6 separate online data sources (PubMed, EMBASE, Cochrane, CINAHL, SportDiscus, and Medline). The successful surgical intervention demonstrates a significant option for elite athletes who wish to return to competition but have been unable to with standard of care conservative management of rib stress fractures.
ABSTRACT
Introduction: Owing to limited clinical clerkships and travel restrictions related to COVID-19, recent medical student mentorship in orthopaedic surgery has been impacted negatively. The purpose of this quality improvement (QI) project was to determine if medical student awareness of orthopaedics as a possible career field may be improved through a mentoring program designed and delivered by orthopaedic residents. Methods: A five-resident QI team developed four educational sessions aimed at a medical student audience. Forum topics included: (1) orthopaedics as a career, (2) fracture conference, (3) splinting workshop, and (4) residency application process. Pre- and post-forum surveys were administered to student participants to assess changes in their perceptions regarding orthopaedic surgery. Data derived from the questionnaires were analyzed with nonparametric statistical tests. Results: Of 18 forum participants, 14 were men and 4 were women. A total of 40 survey pairs were collected, averaging 10 per session. In the all-participant encounter analysis, there were statistically significant improvements in all outcome measures including interest in, exposure to, and knowledge of orthopaedics; exposure to our training program; and ability to interact with our residents. Those undecided regarding their specialty demonstrated larger increases in post-forum responses, suggesting that the learning experience was more impactful for that subgroup. Conclusions: This QI initiative was a successful demonstration of orthopaedic resident mentorship of medical students, wherein perceptions of orthopaedics were influenced favorably by the educational experience. For some students with limited access to orthopaedic clerkships or formal one-on-one mentoring, forums like these may be an acceptable alternative.
ABSTRACT
INTRODUCTION: The inferior glenohumeral ligament (IGHL) complex commonly is assessed by both magnetic resonance imaging (MRI) and magnetic resonance (MR) arthrogram. Our study compared the accuracy of MR arthrogram compared to MRI using arthroscopic correlation as the gold standard. METHODS: A retrospective review of cases reporting an IGHL injury was performed. Seventy-seven cases met inclusion criteria, while five had arthroscopic reports that directly confirmed or refuted the presence of IGHL injury. Two arthroscopic reports confirmed concordant IGHL injuries, while three arthroscopic reports mentioned discordant findings compared to MR. All three discordant cases involved MR arthrogram. Findings included soft tissue edema, fraying of the axillary pouch fibers, and cortical irregularity of the humeral neck. Of the two concordant cases, one was diagnosed by MRI, revealing an avulsion of the anterior band, while the second was diagnosed by MR arthrogram showing ill-defined anterior band fibers. Many cases involved rotator cuff or labral tears, which may have been the focus of care for providers, given their importance for shoulder stability. Additionally, a lack of diagnostic confidence in MR reports may have influenced surgeons in the degree to which they assessed the IGHL complex during arthroscopy. CONCLUSION: Radiologists seemed more likely to make note of IGHL injuries when MR arthrograms were performed; meanwhile, all three discordant cases involved MR arthrogram reads. Therefore, additional larger studies are needed with arthroscopic correlation to elucidate MR findings that confidently suggest injury to the IGHL complex, to avoid false positive radiology reports.
