Background We report the use of botulinum toxin to aid in the treatment of chronic radial collateral ligament insufficiency of the thumb. Case Description Treatment included autograft tendon reconstruction and cast immobilization. Six weeks postoperatively, prior to hand therapy, the patient underwent an ultrasound-guided botulinum neurotoxin A injection into the adductor pollicis muscle to negate its deforming forces on the reconstruction. The patient made an excellent recovery and 1 year postoperatively was pain free and had a stable radial collateral ligament (RCL) upon examination. Literature Review The outcomes of RCL repair and reconstruction are unpredictable, in part, due to the strong opposing forces of the adductor pollicis. Clinical Relevance The use of Botox injection may enhance the outcomes of RCL repair or reconstruction by neutralizing the deforming forces of the adductor muscle.

Background: Unplanned readmission following surgery is a quality metric that helps surgeons assess initiatives targeted at improving patient care. We utilized the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database to determine the rates, causes, and predictors of unplanned 30-day readmissions after outpatient elective hand and elbow surgery. Methods: The ACS-NSQIP database was queried using hand-and-elbow-specific Current Procedural Terminology (CPT) codes to retrospectively identify patients who had undergone outpatient hand or elbow surgery in 2012 and 2013. Patients who required an unplanned readmission to the hospital within 30 days were compared with those who were not readmitted. Preoperative patient characteristics, intraoperative variables, complications, and mortality were compared between the cohorts. Cox proportional hazard models were used to determine independent associations with 30-day unplanned readmission. Results: A total of 14,106 outpatient hand or elbow surgery procedures were identified between 2012 and 2013, and 169 (1.2%) of them were followed by an unplanned readmission. The leading causes of readmission included postoperative infections (19.5%), pain (4.7%), thromboembolic events (4.1%), and pulmonary complications (3.0%). The causes of approximately 1/3 of the readmissions were missing from the database, and these readmissions were likely unrelated to the principal procedure. Independent predictors of readmission included an age of 70 to 84 years (hazard ratio [HR] = 2.83, 95% confidence interval [CI] = 1.67 to 4.78), smoking (HR = 2.23, 95% CI = 1.57 to 3.18), a lower hematocrit (HR = 2.19, 95% CI = 1.38 to 3.46), renal dialysis (HR = 3.32, 95% CI = 1.60 to 6.91), and an elbow procedure (with or without a hand procedure) (HR = 2.19, 95% CI = 1.57 to 3.04). Conclusions: The prevalence of unplanned readmission following outpatient hand and elbow surgery is low. Several modifiable factors, including preoperative smoking and anemia, are associated with unplanned readmission. These data may be helpful in developing quality-control initiatives to target unplanned readmissions following hand and elbow procedures. Level of Evidence: Therapeutic Level IV .

Background The diagnoses of peripheral triangular fibrocartilage complex (TFCC) tears continue to be the subject of numerous investigations. Case Description We describe a novel arthroscopic technique that may be used as an adjunct with other arthroscopic maneuvers to diagnose and confirm repair of peripheral sided TFCC injuries. Literature Review The hook and trampoline tests are intraoperative techniques to diagnose TFCC tears. Clinical Relevance The suction test provides a means to detect peripheral tears and to confirm restoration of its tension post repair.

We report the outcomes of ulnar head replacement with concomitant resurfacing of the sigmoid notch with a lateral meniscal allograft that attempted to recreate the palmar and dorsal radioulnar ligaments in four patients. Patients’ ranges of motion, grip strength, postoperative complications and radiographs were assessed. The mean follow-up was 20 (range 12–28) months. There was an increase in postoperative range of motion with an average increase in grip strength of 43% to the unaffected extremity. All patients experienced marked reduction in their postoperative pain. No patients reported symptoms of implant instability. Distal ulna implant arthroplasty with a lateral meniscal allograft gives favourable short-term outcomes. Level of evidence: IV

Background: Distal radius fractures (DRFs) are common geriatric fractures with the overall incidence expected to increase as the population continues to age. The purpose of this investigation was to compare the short-term complication rates in geriatric versus nongeriatric cohorts following osteosynthesis of DRFs. Methods: The American Board of Orthopaedic Surgery (ABOS) part II database was queried for adult DRF cases performed from 2007 to 2013. Current Procedural Terminology codes were used to identify cases treated via osteosynthesis. Patient demographic information and reported complication data were analyzed. Comparisons between geriatric (age ≥65 years) and nongeriatric (age <65 years) patients were performed. Results: From 2007 to 2013, a total of 9867 adult DRFs were treated via osteosynthesis by ABOS part II candidates. Geriatric patients comprised 28% of the study cohort. Mean age of the geriatric and nongeriatric cohorts was 74 ± 7 and 46 ± 13 years, respectively. There was a greater proportion of female patients ( P < .001) in the geriatric cohort as compared with the nongeriatric cohort. The geriatric cohort demonstrated higher rates of anesthetic complications ( P = .021), iatrogenic bone fracture ( P = .021), implant failure ( P = .031), loss of reduction ( P = .001), unspecified medical complications ( P = .007), and death ( P = .017) than the nongeriatric cohort. The geriatric cohort also showed lower rates of nerve palsy ( P = .028) when compared with the nongeriatric cohort, though no differences in rates of secondary surgery were noted between the two cohorts. Conclusion: Increased rates of complications related to poor bone quality and poor health status may be expected among geriatric patients following osteosynthesis of DRFs. However, geriatric and nongeriatric patients have similarly low rates of secondary surgery. Future studies are needed to delineate the economic, functional, and societal impact of geriatric DRFs treated via osteosynthesis.

Purpose In the surgical treatment of thumb carpometacarpal (CMC) joint arthritis, the effect of mild preoperative metacarpophalangeal (MCP) hyperextension on postoperative functional outcomes is unknown. We sought to examine outcomes after surgical treatment of CMC arthritis in patients with and without mild preexisting MCP deformity. Methods A retrospective review was conducted to analyze the functional outcomes of patients treated for CMC arthritis at a single institution from March 1998 to May 2009. All patients were treated with one of two standard CMC arthroplasty procedures—either ligament reconstruction tendon interposition (LRTI) or a Weilby procedure—and none had additional procedures to address MCP hyperextension. Pre- and postoperative assessments included pinch and grip strength, degree of MCP hyperextension, and thumb radial and palmar abduction. A t-test was used to assume unequal variances. Results A total of 203 patients were followed for an average of 27.3 months. Patients were divided into two groups: (1) patients without preoperative MCP hyperextension (167 patients) and (2) patients with mild but untreated preoperative MCP hyperextension (≤ 30 degrees; 36 patients). All patients underwent either a Weilby procedure (118 patients) or an LRTI; 85 patients). The main difference between techniques was the use of the abductor pollicis longus tendon as a post to secure the flexor carpi radialis (Weilby) or the use of a bone tunnel in the first metacarpal (LRTI). Analysis of the preoperative data showed no difference in the baseline parameters among both the groups, with the exception of MCP hyperextension. Postoperatively, neither the type of CMC procedure nor the presence of MCP hyperextension demonstrated any significant differences in key pinch, tip pinch, grip strength, and radial or palmar abduction of the thumb between the groups. Conclusion There were no statistically significant differences in improvement of functional outcomes after surgery when comparing patients without preoperative MCP hyperextension to patients with untreated MCP hyperextension of less than 30 degrees. Level of Evidence Level III, retrospective comparative study.
