RESUMO
BACKGROUND: Ultrasound provides evaluation of rotator cuff disease with accuracy comparable to that of magnetic resonance imaging. Fluid in the sheath of the long head of the biceps tendon (LHB), identified on ultrasound scan, has been associated with disease of the rotator cuff, LHB, and glenohumeral joint. Prior literature has compared ultrasound findings only with arthrography, and results have been conflicting. Arthroscopy remains the reference standard in assessing accuracy of imaging modalities. We present the first study investigating the significance of fluid in the LHB on ultrasound in predicting subsequent rotator cuff disease identified on arthroscopy. METHODS: Records were reviewed of 175 patients undergoing ultrasound and subsequent arthroscopy under 1 shoulder surgeon. Experienced musculoskeletal radiologists and sonographers performed ultrasound. Ultrasound examination and operating records were collected and analyzed. Data were analyzed using descriptive statistics, correlation, and logistic regression modeling. RESULTS: Highly significant correlation (P < .001; ρ = 0.354) was found between fluid in the LHB sheath and rotator cuff tears on arthroscopy. Statistically significant but weak correlation (P < .05; rho = 0.187) was found between fluid in the LHB sheath and both biceps tendon disease and glenohumeral joint disease. Fluid around the LHB was shown to increase the likelihood of having rotator cuff tear (odds ratio, 2.641; 95% confidence interval, 1.229-5.674) and biceps tendon disease (odds ratio, 2.698; 95% confidence interval, 1.216-5.987). CONCLUSION: This is the first report identifying significant correlation between fluid in the LHB sheath identified on ultrasound and subsequent rotator cuff disease identified at arthroscopy. We recommend routine reporting of fluid in the LHB sheath as it is likely to improve the accuracy of detecting rotator cuff and biceps tendon diseases.

BACKGROUND: Leeches are a well-recognized treatment for congested tissue. This study reviewed the efficacy of leech therapy for salvage of venous congested flaps and congested replanted or revascularized hand digits over a 2-year period. METHODS: All patients treated with leeches between 1 Oct 2010 and 30 Sep 2012 (two years) at Queen Elizabeth Hospital, Birmingham, UK were included in the study. Details regarding mode of injury requiring reconstruction, surgical procedure, leech therapy duration, subsequent surgery requirement and tissue salvage rates were recorded. RESULTS: Twenty tissues in 18 patients required leeches for tissue congestion over 2 years: 13 men and 5 women. The mean patient age was 41 years (range 17-79). The defect requiring reconstruction was trauma in 16 cases, following tumour resection in two, and two miscellaneous causes. Thirteen cases had flap reconstruction and seven digits in six patients had hand digit replantations or revascularisation. Thirteen of 20 cases (65%) had successful tissue salvage following leech therapy for congestion (77% in 10 out of 13 flaps, and 43% in 3 of 7 digits). The rate of tissue salvage in pedicled flaps was good 6/6 (100%) and so was in digital revascularizations 2/3 (67%), but poor in digital re-plants 1/4 (25%) and free flaps 0/2 (0%). CONCLUSIONS: Leeches are a helpful tool for congested tissue salvage and in this study, showed a greater survival benefit for pedicled flaps than for free flaps or digital replantations.

Purpose: Pillar pain is a recognized postoperative complication of carpal tunnel release (CTR). Minimally invasive and alternative surgical techniques can theoretically prevent pillar pain, and the aim of this review was to compare the incidence of pillar pain after standard open CTR and alternative surgical techniques. Methods: MEDLINE, Embase, and Scopus databases were thoroughly searched. Randomized controlled trials comparing minimally invasive surgical techniques to standard open CTR were identified. Data, including surgical technique, number of hands, incidence of pillar pain, and follow-up intervals, were extracted. Odds ratios (OR) were expressed as pillar pain incidence in the intervention group relative to standard open CTR. Results: There were 12 studies included. No statistically significant differences were noted among endoscopic (OR = 0.53, P = .20), flexor retinaculum lengthening (OR = 1.00, P = 1.00), short incision (OR = 0.41, P = .07) or illuminated knife techniques (OR = 0.18, P = .16). There was a statistically significant decrease in pillar pain after minimally invasive CTR (OR = 0.41, 95% confidence interval 0.20-0.86, I2 = 0%, P = .02) between 3- and 6-months follow-up; however, analyses at all other follow-up periods failed to reach statistical significance. Conclusions: Although our findings suggest that standard open CTR may be associated with an increased duration of pillar pain between 3 and 6 months postoperatively, our results suggest that minimally invasive CTR techniques do not affect either the initial development or persistence of pillar pain. Clinical relevance: Our results illustrate the natural history of pillar pain with the majority of cases resolving after 6 months, highlighting the utility of symptomatic and conservative treatments and patient education in the management of pillar pain.
RESUMO
Purpose: The primary purpose of our study was to investigate hamate fractures at a single tertiary hand surgery unit in Western Australia, particularly comparing operative and nonsurgical outcomes. Methods: Patients with hamate and/or hamate plus fifth carpometacarpal injury at our hand unit between 2019 and 2022 were identified. All patients had Quick Disability of the Arm, Shoulder and Hand (QuickDASH) patient-reported outcome measures recorded post treatment. Patients managed operatively and nonsurgically had a period of splinting with plaster of Paris and/or thermoplastic splint for a minimum of 2 weeks. All patients underwent hand therapy. Results: Forty-eight patients with hamate and/or hamate plus fifth carpometacarpal injury were included in this study. Thirteen patients had Milch type 1 fractures, and 35 had Milch type 2 fractures. Six Milch type 1 fractures were managed operatively, and seven were managed nonsurgically. The average QuickDASH score for the operative group was 0.38. The average QuickDASH score for the nonsurgical group was 0.65. Sixteen Milch type 2 fractures were managed operatively, and 19 were managed nonsurgically. The average QuickDASH score for the operative group was 1.3. The average QuickDASH score for the nonsurgical group was 3.5. Conclusions: For Milch type 2 fractures, patient-reported outcome measures were better for the operative group compared with the nonsurgical group. Type of study/level of evidence: Therapeutic IV.
RESUMO
BACKGROUND: Total wrist arthrodesis is a well-established surgical technique that provides reliable pain relief in patients with advanced wrist disease. Key limitations of existing plating systems include hardware pull-out, hardware failure, and nonunion. There is limited literature on the newer style carpometacarpal joint (CMCJ) sparing plating system, produced by Medartis. The objective of this study was to determine the long-term clinical and radiological outcomes of wrist arthrodesis with a CMCJ sparing wrist plate. METHODS: This study retrospectively identified 23 wrist arthrodeses using the Medartis CMCJ sparing plate for review. This study assessed the outcomes of 18 unilateral wrist fusions and 1 bilateral wrist fusion. The study group consisted of 12 men and 5 women with an average age of 56 years (range: 29-82 years) with a mean follow-up period of 17 months. RESULTS: At the time of follow-up, all patients' wrists had fused without postsurgical complication. The final grip strength in the operative hand was 28.2 kg/cm2, which was 87% of the contralateral side. The mean Quick Disabilities of the Arm, Shoulder, and Hand score at follow-up was 23.9, with all patients returning to daily living activities and work. Patients reported minimal pain (1.3/10), with almost all (17/18) satisfied with the outcome of the surgery and describing that they would recommend this procedure. CONCLUSION: Our case series highlights that the Medartis wrist arthrodesis plate is a newer design that is a well-tolerated option for wrist arthrodesis based on clinical assessment, functional hand assessment, and patient satisfaction, when compared with the existing literature on traditional plating systems.
RESUMO
We present a case of an ulna malunion managed with computer-assisted 3-dimensional planned corrective osteotomy in a patient with a history of distal radius fracture treated with open reduction internal fixation and concurrent distal ulna fracture treated conservatively. The distal ulnar diaphyseal deformity was complex and existed in multiple planes, including a clinically significant rotational deformity. Preoperative computed tomography scans were used to plan 3-dimensional guides for the osteotomy, which were subsequently printed and used during surgery. After surgery, our radiologic findings showed a high degree of accuracy and the patient demonstrated pain-free, full range of motion and returned to contact sports 4 months after surgery. This could be a reliable and precise option for complex ulnar diaphyseal malunion corrective surgery.
RESUMO
The authors describe two patients presenting with a previous history of spinal trauma and a several-year history of sensory changes secondary to spinal cord compression. Both patients underwent laminectomy and spinal decompression operations. In both cases intradural bone causing neural compression was removed at operation. Potential mechanisms to explain intradural ossification and the relevant literature are reviewed.

BACKGROUND: The present study aimed to compare medium-term clinical outcomes of patients following arthroscopic subacromial decompression (ASAD): those with intact rotator cuff with two groups of increasing size of partial thickness bursal-side tears. METHODS: Patients undergoing shoulder arthroscopy by a single surgeon had pre- and postoperative Constant scores prospectively recorded. Arthroscopic surgery included the assessment of any supraspinatus tears using the Ellman criteria, as well as ASAD and cuff debridement. Groups were created based on the status of rotator cuff and size of bursal tear. Outcome in these patient groups was then compared and analyzed. RESULTS: Seventy-four patients were suitable for inclusion in the study: 32 patients without a cuff tear; 21 patients with a cuff tear of 9 mm or less in length; and 21 patients with a cuff tear of 10 mm or more in length. Baseline characteristics of the three groups were similar. All three groups showed a significant improvement in their Constant scores following surgery. There was, however, no significant difference in Constant scores between the three groups. CONCLUSIONS: The results of the present study show that patients with varying sizes of bursal-side tears respond to ASAD as well as those with no rotator cuff tear.
RESUMO
OBJECTIVES: To compare mechanical stability of angle-stable locking construct with four screws with conventional five screw locking in intramedullary nailed distal tibia fractures under cyclic loading. METHODS: Ten pairs of fresh-frozen human cadaveric tibiae were intramedullary nailed and assigned to either an angle-stable locking construct consisting of four screws or conventional five-screw locking. After simulating an unstable distal two-fragmental 42-A3.1 fracture, the specimens were mechanically tested under quasistatic and cyclic sinusoidal axial and torsional loading. RESULTS: Bending stiffness of the angle-stable and the conventional fixation was 644.3 N/° and 416.5 N/°, respectively (P = 0.075, power 0.434). Torsional stiffness of the angle-stable locking (1.91 Nm/°) was significantly higher compared with the conventional one (1.13 Nm/°; P = 0.001, power 0.981). Torsional play of the angle-stable fixation (0.08°) was significantly smaller compared with the conventional one (0.46°; P = 0.002, power 0.965). The angle-stable locking revealed significantly less torsional deformation in the fracture gap after one cycle (0.74°) than the conventional one (1.75°; P = 0.005, power 0.915) and also after 1000 cycles (angle-stable: 1.56°; conventional: 2.51°; P = 0.042, power 0.562). Modes of failure were fracture of the distal fragment, loosening of distal locking screws, nail breakage, and their combination, equally distributed between the groups (P = 0.325). CONCLUSIONS: Both the angle-stable locking technique using four screws and conventional locking consisting of five screws showed high biomechanical properties. Hence, angle-stable locking reflects a potential to maintain fixation stability while reducing the number of locking screws compared with conventional locking in intramedullary nailed unstable distal tibia fractures.
