Background: There has been a recent increase in the use of headless compression screws for fixation of metacarpal neck and shaft fractures as they offer several advantages, and minimal complications have been reported. This study aimed to evaluate the clinical complications and their solutions following retrograde intramedullary headless compression screw fixation of metacarpal fractures. We describe complications and the approach to their management. Methods: We performed a multicenter case series through retrospective review of all patients treated with intramedullary headless screw fixation of metacarpal fractures by 3 fellowship-trained hand surgeons. Patient demographics, implant used, type of complication, pre- and postoperative radiographs, operative reports, and sequelae were reviewed for each case. We defined complications as infection, loss of fixation, hardware failure, malrotation, nonunion, malunion, metal allergy, and any repeat surgical intervention. Results: Four complications (2.5%) were identified through the review of 160 total metacarpal fractures. One complication was a nickel allergy, one was a broken screw after repeat trauma, and 2 patients had bent intramedullary screws. Screw removal in 3 patients was simple and without complications or persistent limitations. One bent screw with a refracture was left in place. No serious complications were seen. Conclusion: Intramedullary screw fixation of metacarpal fractures is safe with a low incidence of complications (2.5%) that can be safely and effectively managed.

Category: Sports Introduction/Purpose: There remains controversy over the ideal implant for intramedullary screw fixation of fifth metatarsal Jones fractures. Promising results have separately been reported for both indication-specific partially threaded screws and headless compression screws. The purpose of this study was to compare clinical and radiographic results between Jones fracture patients treated with indication-specific partially threaded screws to variable-pitched headless compression screws. We also evaluated the association of various patient and fracture characteristics with surgical failure. Methods: We performed a retrospective review and comparative analyses of all Jones fractures treated with primary intramedullary screw fixation by 4 foot and ankle fellowship-trained orthopaedic surgeons at a single institution from 1995 through 2015. Exclusion criteria included concomitant foot or ankle procedures and revision surgery. Charts were reviewed for patient and injury characteristics, implant, and postoperative course. Serial radiographs were examined for fracture classification (Torg and anatomic zone) and radiographic union. Primary endpoint was number of surgical failures, defined as delayed union, nonunion, or refracture. Secondary endpoints included time to each of radiographic union, weight bearing, and pain resolution. Data were analyzed using independent T test, one-way ANOVA, chi-square, and correlation analyses with significance defined as p < 0.05. Results: Fifty-nine feet were reviewed with mean age 30 years and follow-up 9.6 months. Forty-seven received a partially threaded screw (PT) and 12 feet a headless compression screw (HC). The PT group had more failures (10/47, 21.3% vs. 1/12, 8.3%; p=0.31) and more weeks to full weight (4.2 vs. 3.3, p=0.06), without significant differences in time to radiographic union or pain resolution. Most failures were delayed unions. Pooled union rate was 96.6%. Correlated with failure were age (r=0.469, p < 0.001), diabetes (r=0.390, p=0.002), and BMI (r=0.281, p=0.03), without significant correlation for tobacco, gender, or weight. Compared to Torg 1 and 2, Torg 3 fractures had greater time to pain resolution and radiographic union, age, weight, and BMI. No differences were found between zone II and III fractures. Conclusion: To our knowledge, this is the first reported clinical comparison between indication-specific partially threaded screws (PT) and headless compression screws (HC) for treating Jones fractures. This is also one of the largest clinical series on the subject. The two groups had similar clinical and radiographic results, both with high union rates. While most failures were delayed unions that ultimately healed, the 21% failure rate in the PT group is concerning and may warrant further investigation. Increasing patient age, diabetes, and BMI were associated with worse outcomes. These data support headless compression screw fixation as a viable treatment for Jones fractures.

Purpose: Open fixation of acute fractures, delayed union and non-union of the hamate hook through a palmar approach has been reported. Minimal invasive fixation using a dorsal percutaneous approach and a headless cannulated mini-screw is another option not commonly considered. The authors present their case series of patients who underwent dorsal percutaneous fixation of acute fractures and delayed union of the hamate hook. Methods: This study retrospectively reviewed six consecutive patients (five male patients and one female patient) with non-displaced acute fractures (< 8 weeks) and delayed union (8 to 12 weeks) of the hamate hook treated with dorsal percutaneous cannulated mini-screw fixation. The indications for surgery included wrist pain, patient refusal of conservative treatment, and prevention of non-union and hook excision. Exclusion criteria included displacement or inadequate size of the hamate hook, previous surgery, associated carpal injury, flexor tendon rupture, and median or ulnar nerve lesion in the carpal tunnel and Guyon's canal respectively. Each fracture was visualized by radiography and computed tomography before and after the intervention. Results: Anatomically correct fixation of the hamate hook with central screw positioning was achieved in all patients. No displacement or disruption of the cortical shell of the hook was observed. The union rate was 100% with all patients being able to resume their pre-injury activities after an average of seven weeks from surgery. Conclusions: This pilot study demonstrates that non-displaced acute fractures and delayed union of the hamate hook can be treated successfully by dorsal percutaneous cannulated mini-screw fixation with minimal morbidity and complications.

We developed a new internal fixation method for extra-articular fractures at the base of the proximal phalanx using a headless compression screw to achieve rigid fracture fixation through a relatively easy technique. With the metacarpophalangeal joint of the involved finger flexed, a smooth guide-pin is inserted into the intramedullary canal of the proximal phalanx through the metacarpal head and metacarpophalangeal joint. Insertion tunnels are made over the guide-pin using a cannulated drill. Then, a headless cannulated screw is placed into the proximal phalanx. All of five fractures treated by this procedure obtained satisfactory results.

Headless Compression Screws

Background: Management of scaphoid nonunions with bone loss varies substantially. Commonly, internal fixation consists of a single headless compression screw. Recently, some authors have reported on the theoretical benefits of dual-screw fixation. We hypothesized that using 2 headless compression screws would impart improved stiffness over a single-screw construct. Methods: Using a cadaveric model, we compared biomechanical characteristics of a single tapered 3.5- to 3.6-mm headless compression screw with 2 tapered 2.5- to 2.8-mm headless compression screws in a scaphoid waist nonunion model. The primary outcome measurement was construct stiffness. Secondary outcome measurements included load at 1 and 2 mm of displacement, load to failure for each specimen, and qualitative assessment of mode of failure. Results: Stiffness during load to failure was not significantly different between single- and double-screw configurations ( P = .8). Load to failure demonstrated no statistically significant difference between single- and double-screw configurations. Using a qualitative assessment, the double-screw construct maintained rotational stability more than the single-screw construct ( P = .029). Conclusions: Single- and double-screw fixation constructs in a cadaveric scaphoid nonunion model demonstrate similar construct stiffness, load to failure, and load to 1- and 2-mm displacement. Modes of failure may differ between constructs and represent an area for further study. The theoretical benefit of dual-screw fixation should be weighed against the morphologic limitations to placing 2 screws in a scaphoid nonunion.

Abstract Background Metacarpal shaft fracture is a common fracture in hand trauma injuries. Surgical intervention is indicated when fractures are unstable or involve considerable displacement. Current fixation options include Kirschner wire, bone plates, and intramedullary headless screws. Common complications include joint stiffness, tendon irritation, implant loosening, and cartilage damage. Objective We propose a modified fixation approach using headless compression screws to treat transverse or short-oblique metacarpal shaft fracture. Materials and methods We used a saw blade to model transverse metacarpal neck fractures in 28 fresh porcine metacarpals, which were then treated with the following four fixation methods: (1) locked plate with five locked bicortical screws (LP group), (2) regular plate with five bicortical screws (RP group), (3) two Kirschner wires (K group), and (4) a headless compression screw (HC group). In the HC group, we proposed a novel fixation model in which the screw trajectory was oblique to the long axis of the metacarpal bone. The entry point of the screw was in the dorsum of the metacarpal neck, and the exit point was in the volar cortex of the supracondylar region; thus, the screw did not damage the articular cartilage. The specimens were tested using a modified three-point bending test on a material testing system. The maximum fracture forces and stiffness values of the four fixation types were determined by observing the force–displacement curves. Finally, the Kruskal–Wallis test was adopted to process the data, and the exact Wilcoxon rank sum test with Bonferroni adjustment was performed to conduct paired comparisons among the groups. Results The maximum fracture forces (median ± interquartile range [IQR]) of the LP, RP, HC, and K groups were 173.0 ± 81.0, 156.0 ± 117.9, 60.4 ± 21.0, and 51.8 ± 60.7 N, respectively. In addition, the stiffness values (median ± IQR) of the LP, HC, RP, and K groups were 29.6 ± 3.0, 23.1 ± 5.2, 22.6 ± 2.8, and 14.7 ± 5.6 N/mm, respectively. Conclusion Headless compression screw fixation provides fixation strength similar to locked and regular plates for the fixation of metacarpal shaft fractures. The headless screw was inserted obliquely to the long axis of the metacarpal bone. The entry point of the screw was in the dorsum of the metacarpal neck, and the exit point was in the volar cortex of the supracondylar region; therefore the articular cartilage iatrogenic injury can be avoidable. This modified fixation method may prevent tendon irritation and joint cartilage violation caused by plating and intramedullary headless screw fixation.
