RESUMO
BACKGROUND: Metacarpal shaft fracture is a common type of hand fracture. Numerous studies have explored fixing transverse fractures in the midshaft of the metacarpal bone. However, this section of the metacarpal bone is often susceptible to high-energy injury, resulting in comminuted fracture or bone loss. In such cases, wedge-shaped bone defects can develop in the metacarpal shaft, increasing the difficulty of performing fracture fixation. Notably, the research on this type of fracture fixation is limited. This study compared the abilities of four fixation methods to fix metacarpal shaft fractures with wedge-shaped bone defects. METHODS: In total, 28 artificial metacarpal bones were used. To create wedge-shaped bone defects, an electric saw was used to create metacarpal shaft fractures at the midshaft of each bone. The artificial metacarpal bones were then divided into four groups for fixation. The bones in the first group were fixed with a dorsal locked plate (DP group), those in the second group were fixed with a volar locked plate (VP group), and those in the third group were fixed by combining dorsal and volar locked plates (DP + VP group), and those in the fourth group were fixed with two K-wires (2 K group). Cantilever bending tests were conducted using a material testing machine to measure yielding force and stiffness. The four groups' fixation capabilities were then assessed through analysis of variance and Tukey's test. RESULTS: The DP + VP group (164.1±44.0 N) achieved a significantly higher yielding force relative to the 2 K group (50.7 ± 8.9 N); the DP group (13.6 ± 3.0 N) and VP group (12.3 ± 1.0 N) did not differ significantly in terms of yielding force, with both achieving lower yielding forces relative to the DP + VP group and 2 K group. The DP + VP group (19.8±6.3 N/mm) achieved the highest level of stiffness, and the other three groups did not differ significantly in terms of stiffness (2 K group, 5.4 ± 1.1 N/mm; DP group, 4.0 ± 0.9 N/mm; VP group, 3.9 ± 1.9 N/mm). CONCLUSIONS: The fixation method involving the combined use of dorsal and volar locked plates (DP + VP group) resulted in optimal outcomes with respect to fixing metacarpal shaft fractures with volar wedge bone defects.

INTRODUCTION: Hand fractures are associated with significant morbidity. Current management standards often result in prolonged immobilization, stiffness, and delayed return to functional use. Intramedullary (IM) compression screws offer minimal soft tissue disruption and early postoperative active motion. In this study, we describe our outcomes after intraosseous fracture fixation using IM cannulated headless screws for a multitude of fracture patterns. METHODS: This study is a retrospective review of patients who underwent IM screw placement for fixation of metacarpal and phalangeal fractures by a single surgeon from 2017 to 2022. Data were collected to include patient demographics, fracture details, postoperative complications, and follow-up. Time to range of motion and return to unrestricted motion was recorded. RESULTS: There were 69 patients with 92 fractures (n = 54 metacarpal, n = 38 phalanx). The median patient age was 45 years (range, 18-89 years) with 75.4% males. Majority presented with a single fracture (n = 50, 72.5%), and 38 patients (55.1%) had open fractures. Small finger was the most affected digit (n = 35, 37.6%). The median time to allow range of motion from surgery was 8.7 days (interquartile range, 0-32) with 32 days (interquartile range, 10-62) for unrestricted use of the hand. Thirty-five patients (50.7%) were allowed controlled motion from the first postoperative day. One patient had loss of reduction requiring reintervention for hardware removal, and 1 patient had superficial skin infection managed with oral antibiotics. CONCLUSIONS: Our findings indicate that the IM screw provides reliable fixation for a wide variety of fracture patterns with a low complication rate and offers early return to functional use.

INTRODUCTION: Metacarpal fractures account for 25%-50% of all hand fractures and may negatively impact hand function and ability to work. Percutaneous transverse pinning of non-articular metacarpal fractures allows mobilisation immediately after the procedure. METHODS: Between March 2017 and February 2022, 56 patients undergoing percutaneous transverse pinning for unstable metacarpal fractures were prospectively recruited. We investigated surgical outcomes in terms of Patient-rated Wrist/Hand Evaluation (PRWHE) and pre-and post-operative radiographic evaluation. The Student t-test was used to compare the means of PRWHE values after surgery. Statistical significance was set at p < 0.05. RESULTS: The mean age was 40.21 ± 17.9 years (range of 16 to 86 years). The average operating time was 27.96 min. The mean follow-up period was 14.3 ± 6.4 months (from 2 to 41 months). The mean PRWHE score was 6.5 ± 1.8. None of the patients had clinically observable rotational deformities, and the functional outcomes were satisfactory. CONCLUSION: Percutaneous transverse pinning for non-articular metacarpal fractures restores excellent function, and imaging results are satisfactory. Further high-quality clinical trials are required to validate these results on a larger scale. LEVEL OF EVIDENCE: II, prospective cohort study.

PURPOSE OF THE STUDY: The purpose of this study was to assess the patient experience of trapeziectomy under WALANT for trapeziometacarpal joint (TMJ) osteoarthritis (OA) in a prospective study with 2-year follow-up. MATERIAL AND METHODS: The study included 23 patients with TMJ OA undergoing trapeziectomy with WALANT. All patients were seen by a hand therapist preoperatively and at 3, 12, and 24 months postoperatively. At each visit, VAS pain scores, thumb range of motion, grip strength, and Disabilities of the Arm, Shoulder and Hand (DASH) score were assessed. The Picker Patient Experience (PPE-15) questionnaire was administered within 2 weeks of surgery. RESULTS: All 23 patients completed the PPE-15 questionnaire. Their mean age was 64 years. The 21 patients who remained at the 24-month follow-up all said they would choose the same anaesthesia method again. At this follow-up, VAS pain scores, thumb range of motion, key pinch grip and DASH scores had improved significantly, while thumb opposition and hand grip strength remained largely unchanged. The majority of patients felt well informed before and during the procedure, and all patients rated pain relief as good or satisfactory. Nearly 40% of patients reported receiving inadequate information about the postoperative medications. DISCUSSION: Patients have a positive attitude to trapeziectomy with WALANT, and seem to prefer WALANT over other methods of anaesthesia. Trapeziectomy with WALANT for TMJ OA is a safe procedure and appears to give a functional outcome similar to trapeziectomy under general anaesthesia. CONCLUSIONS: Trapeziectomy with WALANT for TMJ OA is safe, preferred by patients and has similar clinical outcome as trapeziectomy in general anesthesia. KEY WORDS: trapeziectomy, osteoarthritis, WALANT.

Endoscopic carpal tunnel release (ECTR) techniques have been established as a successful treatment for carpal tunnel syndrome and have proven equally effective as traditional open carpal tunnel release (OCTR) techniques in relieving pain and numbness. However, patients who undergo OCTR are more likely to experience scar tenderness and pillar pain and take longer to return to work. We present here a method of metacarpal small incision for carpal tunnel release (MSICTR) as a safe, reliable, cost-effective alternative surgical decompression of the median nerve of the wrist. This technique utilizes a metacarpal small incision and direct visualization of the median nerve and carpal tunnel contents, reducing the risk of permanent injury and neurasthenia when compared to traditional OCTR. MSICTR is also suitable for the examination of the median nerve, surrounding tendon sheath, or space-occupying lesions. MSICTR is associated with shorter operation times, less postoperative pain, faster recovery, and improved cosmetic results when compared to traditional OCTR. Therefore, MSICTR is an effective surgical decompression of the median nerve for the treatment of carpal tunnel syndrome.

Metacarpal and phalanx fractures are common injuries that can often be managed nonoperatively with satisfactory clinical outcomes. However, loss of normal finger alignment including malrotation and severe angulation as well as intra-articular deformities can lead to functional deficits which may benefit from operative intervention. There are numerous surgical options to correct malunions and the correct choice varies based on the injury pattern, concurrent injuries/complications, and surgeon's preference. While these surgeries can be technically demanding, successful treatment can lead to good results with satisfactory deformity correction and patient function.

BACKGROUND Fracture of the fifth metacarpal of the hand is due to trauma to the clenched fist. The non-displaced fracture can be treated by splinting and immobilization, but fracture dislocation requires individualized management to ensure the return of function. The Jahss maneuver for reduction of volar displaced metacarpal neck fractures involves flexion of the metacarpophalangeal and proximal interphalangeal joint at 90°, with the proximal phalanx used to reduce the metacarpal head. This report is of a 25-year-old male Italian pianist with a displaced fifth metacarpal neck fracture successfully treated by reduction using the Jahss maneuver and K-wire attachment of subchondral bone to the metacarpal. CASE REPORT A pianist presented with a trauma to his right hand due to punching a wall. Radiograph images demonstrated an angulated, displaced right fifth neck fracture. A specific approach was decided, considering the complexity of the musical movements and the patient's performance needs. After fracture's reduction by the Jahss maneuver, 2 retrograde cross-pinning K-wires were inserted at the subchondral bone of the metacarpal head. Healing under splinting was uneventful, and the K-wires were removed after 45 days. At 4 months after surgery, the patient had complete recovery of both range of motion and strength. CONCLUSIONS Our technique avoided piercing the metacarpophalangeal joint capsule, preventing extensor tendon damage, dislocation, instability, and pain and retraction of the extensor cuff. This novel mini-invasive technique successfully achieved early metacarpophalangeal joint motion, joint stability, and complete recovery of movements in all planes.

The majority of phalangeal and metacarpal fractures will proceed to union when appropriately treated. However, when a nonunion does occur, it can lead to significant functional impairment for patients and societal costs. Operative intervention is typically required in these cases, but the technique can vary depending on each individual patient scenario. This article provides an overview of nonunions of the metacarpals and phalanges in the hand, including incidence, risk factors, current treatment options, and postoperative care.

PURPOSE: Compare two simple ways for treating boxer's fractures in active adults; conservative management by ulnar gutter slab and transverse pinning in fixation of fifth metacarpal's neck fracture regarding union, functional outcomes, and complications. PATIENTS AND METHODS: Ninety patients with fifth metacarpals' neck fractures with palmar angulation (30-70°) were managed either conservatively by an ulnar gutter slab or surgically by transverse pinning technique from January 2020 to December 2021. Only 84 patients completed a 1-year follow-up. Patients with old, open, or mal-rotated fractures were excluded. The block-randomization method was used to create equal groups. Patients were evaluated clinically and radiologically every 2-3 weeks until union, then at 6 and 12 months. Functional assessment at the final visit was done using the quick DASH score, total active motion (TAM), and total Active Flexion (TAF). RESULTS: The mean radiological union time for the conservative group in this study was 7.76 weeks, while for the transverse pinning group, it was 7.38 weeks. There was no statistically significant difference between the two techniques regarding union rates and functional outcomes. All patients returned to their pre-injury jobs and level of activity. CONCLUSION: Both conservative management in ulnar gutter slab and percutaneous transverse pinning are considered effective methods in the treatment of simple extra-articular fifth metacarpal neck fractures with angulation between 30 and 70 degrees (AO: 77 A3.1). The functional and radiological results using both methods were satisfactory and statistically comparable.

Background: Intramedullary screws (IMS) have become a viable option for metacarpal fracture fixation. To further appraise their utility, this study assessed clinical and patient-reported short- and medium-term outcomes of IMS fixation for extra-articular metacarpal fractures. Methods: A retrospective cohort study was performed in a series of 32 patients (with a total of 37 fractures) who underwent metacarpal fracture fixation over a 42-month period between January 2020 and July 2023. Results: Mean time for return to work was 39.8 days; mean time for return to full function was 88.4 days; total active motion was 250.7° (range: 204.9-270.9); Quick Disabilities of the Arm, Shoulder and Hand score was 2.3 (range: 0-22.7); mean visual analogue pain score was 0.9 out of 10 (range: 0-6) and a single complication was observed. Conclusions: The use of IMS in metacarpal fracture fixation is a practicable surgical option. IMS fixations yields a satisfactory duration for return to function, good postoperative range of movement, modest pain scores and low rates of complications. Level of Evidence: Level IV (Therapeutic).

BACKGROUND: Capitate osteonecrosis is a rare condition that mainly presents in young patients with chronic wrist pain. Treatment aims to address pain, arthritic changes, or carpal instability. METHODS: We present the surgical technique and outcomes of using a vascularized pedicled second metacarpal base transferred on the second dorsal metacarpal artery to treat capitate osteonecrosis in a 20-year-old female secretary, former gymnast, and a 25-year-old female student with acute lymphoblastic leukemia. These patients presented with idiopathic chronic wrist pain with MRI showing capitate osteonecrosis with preserved carpal height and intact articular cartilage. RESULTS: After 2 years of follow-up, both patients endorsed pain resolution and demonstrated preservation of wrist motion and grip strength with evidence of capitate healing on plain radiographs. Case 1 demonstrated grip strength 60 lbs., pinch strength 5 lbs., and wrist flexion-extension arc of 70 to 80°. Case 2 had grip strength 31 lbs., pinch strength 9 lbs., and wrist flexion-extension arc of 40 to 30° on the left. CONCLUSION: Vascularized pedicled second metacarpal base transferred on the second dorsal metacarpal artery can be successfully used in the management of capitate osteonecrosis and offers advantages over other vascularized bone grafts for capitate osteonecrosis.

Background: This study introduces a novel method for the management of closed metacarpal neck fractures. Kirschner wires (K-wire) are introduced in a retrograde and the wires withdrawn through skin proximally at the base of the metacarpal. The fracture is reduced using traction and the reduction is maintained by antegrade advancement of the K-wires. The aim of this study is to report the outcomes of this technique. Methods: A total of 36 patients with severely angulated closed metacarpal neck fractures underwent reduction and fixation using this novel method from January 2017 to December 2020 in centres in Ireland and Saudi Arabia. We performed a retrospective review of these patients' clinical data examining their outcomes. Results: Six months postoperatively, all fractures demonstrated bony union and correction of angulation. All patients exhibited excellent range of motion (ROM) with no significant impairment of hand function. Conclusions: The method detailed here is a simple, minimally invasive and reliable technique that has not previously been described. It is suitable for use in the management of closed metacarpal neck fractures of the fourth and fifth metacarpal, with dorsal angulation greater than 60°. Level of Evidence: Level IV (Therapeutic).

The purpose was to compare clinical and radiological outcomes between two fixation techniques used to treat extra-articular fractures involving the base of the thumb metacarpal: retrograde intramedullary cannulated headless screw (RICHS) and locking plate (LP). Fifty-one patients who underwent RICHS (n = 22) or LP fixation (n = 29) from January 2010 through 2020 were included in this retrospective case-control study with mean follow-up 39 months. No inter-group differences were observed comparing mean time to radiological union, grip strength, range of motion, pain severity or QuickDASH scores. Mean surgery time was shorter with RICHS (18.9 min) than with LP fixation (44.4 min). Mean time to return to work or routine activities was less in RICHS than LP (22 vs. 32 days), as was the percentage of patients requiring hardware removal (0% vs. 44.8%). We conclude that RICHS fixation requires less operating time and yields faster post-operative return to full function and fewer secondary procedures.

Objetivos: Comparar el tratamiento de pacientes con fracturas oblicuas o espiroideas largas de metacarpianos, mediante reducción abierta y fijación interna con tornillos interfragmentarios solos o placas y tornillos. Materiales y métodos: Se realizó un estudio retrospectivo comparativo entre 2 grupos de pacientes: uno con 24 pacientes tratados con tornillos interfragmentarios solos y otro con 17 pacientes tratados mediante osteosíntesis con placas y tornillos. En ambos, se utilizó un abordaje longitudinal dorsal, y se les indicó inmovilización posoperatoria con valva de yeso y rehabilitación con el mismo equipo de terapistas ocupacionales. Tras un seguimiento mínimo de 12 meses, se evaluaron los resultados con el puntaje DASH, la movilidad activa total, la distancia pulpejo-palma y la fuerza con dinamometría comparativa. Se consideró significativo un valor p <0,05. Resultados: El tiempo promedio de seguimiento fue de 24.5 meses (rango 12-43).No se hallaron diferencias estadísticamente significativas en el puntaje DASH, la movilidad activa total, la distancia pulpejo-palma y la fuerza. El tiempo hasta el reingreso laboral fue inferior en el grupo tratado con placas y tornillos, aunque se registraron dos casos de retiro de material, sumado, en uno de ellos, a adherencia tendinosa (tenólisis). Conclusiones: El tratamiento de pacientes con fracturas oblicuas o espiroideas largas de metacarpianos, mediante tornillos interfragmentarios solos o placas y tornillos logró resultados similares, se destaca el menor tiempo hasta la reincorporación laboral y la mayor cantidad de complicaciones con placas y tornillos.

Objective: To compare open reduction and internal fixation with interfragmentary screws and with plates and screws for the treatment of long oblique or spiral metacarpal fractures. Materials and methods: A comparative retrospective study was carried out between 2 groups of patients treated surgically. In the first group, 24 patients were treated with interfragmentary screws and in the second group, 17 patients were treated with plate and screw osteosynthesis. A dorsal longitudinal approach was used. Postoperatively, immobilization was performed using a plaster splint; both groups followed rehabilitation with same occupational therapist team. After a minimum follow-up of 12 months, they were evaluated with the DASH score, total active motion (TAM), pulp-to-palm distance, and comparative contralateral dynamometry. A p value < 0.05 was considered significant. Results: The average follow-up was 24.5 months (range 12-43 months). There were no statistically significant differences in DASH, TAM, pulp-to-palm distance, and strength. The group treated with plate and screw fixation returned to work earlier, although there were two cases of implant removal, in addition to tendon adherence (tenolysis) in one of them. Conclusions: The treatment of patients with long oblique or spiral metacarpal fractures with interfragmentary screws or plates and screws showed similar outcomes; the treatment with plate and screws allowed an earlier return to work but had a greater number of complications.

Materiales & Métodos Serie de casos en un centro de cuarto nivel de complejidad entre el 2005 y 2016 de pacientes con fractura de escafoides en seudoartrosis sometidos a cirugía de revisión con injerto vascularizado de la primera arteria dorsal metacarpiana según la técnica de Bertelli. Se tomaron datos de historias clínicas, que se analizaron con medidas descriptivas de resumen. Resultados se analizaron 11 pacientes con una edad promedio de 30,1 años. El 72,7% fue llevado a osteosíntesis como manejo inicial. El procedimiento de revisión se realizó en una mediana de 380 días. Se reportaron complicaciones pos-quirúrgicas: necrosis del injerto en un paciente, necesidad de re-intervención en cuatro y no hubo infecciones. En el 72,7% se observó consolidación de la fractura y ocurrió en promedio a los 7,6 meses. La mitad de los pacientes tuvieron un puntaje DASH de 9 o menos y reportaron percepción de dolor leve - moderado el 90,9%. La mediana de seguimiento fue 14 meses. Discusión la ventaja de esta técnica es su reproducibilidad y versatilidad, pues su pedículo vascular constante y de buena longitud, permite utilizarse por un abordaje dorsal o palmar y para no consolidaciones del polo proximal, cintura o polo distal del escafoides. Este estudio mostró buenos resultados clínicos y funcionales, asociados a una baja tasa de complicaciones. Nivel de evidencia IV
Background The aim of study is to describe the clinical, functional, and radiological results in patients with pseudoarthrosis of scaphoid fractures who that underwent surgery using Bertelli's et al. technique. Methods Case series of patients with nonunion of scaphoid fractures in a high complexity care center between 2005 and 2016, who underwent revision surgery with vascularized bone graft of the first metacarpal dorsal artery according to Bertelli's et al. technique. Data were collected from clinical records, and it waswere analyzed using descriptive summary measures. Results The analysis included 11 patients with a mean age of 30,1 years (S.D: 9). 72,7% of the patients underwent conventional osteosynthesis as the initial approach. The revision surgery was performed with a median of 380 days (interquartile range: 194-470); there were no intraoperative complications. Post- surgery complications, such as graft necrosis, were reported in a one patient (9,1%), the need of for re-intervention in four patients and there were no infection related complications. Fracture union was seen in 72,7% patients in a mean of 7,6 months (S.D: 2,9) after the intervention. Half of the patient had a DASH score of 9 points or less. 54,5 reported pain as mild, 36,4% as moderate and without pain 9,1%. The median follow up period was 14 months and only one patient developed carpal arthritis. Discussion The advantage of this surgical technique is its reproducibility and versatility, thanks due to the constant and long vascular pedicle; this allows using dorsal or palmar approaches, as well as for the management of scaphoid nonunions of the proximal pole, waist, or distal pole. This study shows good clinical and functional results outcomes with a low rate of complications. Evidence Level IV

El tumor pardo, también conocido como osteoclastoma ó como osteítis fibrosa quística, es un tumor lítico, que se presenta en hiperparatiroidismo (primario, secundario y terciario), aunque su presentación habitual es altamente invasiva, no tiene potencial de malignidad. Los tumores pardos en la mano son muy poco frecuentes y existen solo algunos reportes de casos. Presentamos un paciente masculino de 18 años con una tumoración dura, no móvil, adherida a planos profundos en región dorsal de la mano derecha sobre el cuarto metacarpiano, que además limita la flexión y extensión del cuarto dedo sin alterar su función neurovascular. El paciente fue sometido a resección de la tumoración que involucraba por completo al cuarto metacarpiano derecho, además se realizó un abordaje lateral directo en miembro pelvico izquierdo para tomar un injerto autólogo de peroné no vascularizado. Es importante la detección temprana de este tipo de tumores y se debe dar un adecuado seguimiento, ya que, al progresar, generan una destrucción ósea importante y el tratamiento se vuelve de mayor complejidad. En etapas tempranas, el manejo agresivo con resección y aporte óseo puede evitar secuelas funcionales. El uso de injerto no vascularizado de peroné de seis centímetros para la sustitución del cuarto metacarpiano por osteolísis secundaria a un tumor pardo es una alternativa adecuada de tratamiento que permite la preservación estético funcional de la mano.
The brown tumour, also known as osteoclastoma, or as osteitis fibrosa cystica, is a lytic tumour, which occurs in hyperparathyroidism (primary, secondary, and tertiary), although its usual presentation is highly invasive, has no potential for malignancy. Brown tumours of the hand are sporadic, and there are only few case reports. The case is presented of an 18-year-old male patient with a solid, non-mobile tumour, adhered to deep planes, in the dorsal region of the right hand over the fourth metacarpal. This also limited the flexion and extension of the fourth finger, but did not show alterations in the neurovascular function of the finger. The patient underwent a tumour resection that completely involved the right fourth metacarpal. A direct lateral approach was made in the left pelvic limb to perform a non-vascularised autologous fibular graft. Early detection of this type of tumour is important, and an adequate follow-up must be carried out, since when they progress, they generate significant bone destruction and the treatment becomes more complex. In early stages, aggressive management of resection and bone support can prevent functional sequelae.

Resumen: Antecedentes: Las fracturas de los metacarpianos comprenden de 18 a 44% de las fracturas de la mano. La mayoría de las fracturas simples de cuello y transversales diafisiarias de metacarpianos pueden ser tratadas de manera conservadora con buenos resultados. Sin embargo, en el caso de fracturas inestables no existe un estándar de oro para la osteosíntesis y ningún método ha mostrado hasta la fecha superioridad sobre los demás. Recientemente ha habido publicaciones sobre osteosíntesis con tornillos canulados centromedulares sin cabeza retrógrados con buenos resultados funcionales en fracturas de cuello y transversales diafisiarias de metacarpianos. Material y métodos: Series de casos con seguimiento a corto plazo tratados con osteosíntesis retrógrada con tornillos canulados sin cabeza en nueve fracturas de cuello de quinto metacarpiano, una de cuello de cuarto metacarpiano y una transversal diafisiaria de quinto metacarpiano. Resultados: Todos los pacientes lograron consolidación radiográfica y al mes de seguimiento tenían arcos de movimiento completos y realizaban actividades habituales. Una paciente con mano traumática y fractura de quinto metacarpiano presentó limitación de arcos de movimiento. En un caso con hueso osteoporótico y conminución de cortical volar no logramos evitar la pérdida de altura con tornillos, por lo que utilizamos clavillos Kirschner. Conclusión: La osteosíntesis mínimamente invasiva con tornillos canulados retrógrados sin cabeza es una buena opción para el tratamiento de fracturas transversales de diáfisis y de cuello de metacarpianos inestables porque es mínimamente invasiva y permite movilización y regreso temprano a actividades habituales.
Abstract: Metacarpal fractures comprise 18 to 44% of hand fractures. Fractures from the second to the fifth metacarpals are 88% of the metacarpal fractures and fractures of the fifth metacarpals are the most common. Fractures of the neck of the fifth metacarpal are about 20% of all the hand fractures. Most of these fractures can be treated conservatively with good functional results. However, for those neck and shaft unstable fractures that need surgical treatment, there is no gold standard for osteosynthesis. Recently, there have been reports of minimally invasive osteosynthesis using headless retrograde intramedullary cannulated screws with good functional results. Material and methods: We report our short term experience treating nine fifth metacarpal neck fractures, one fourth metacarpal neck fracture and a transverse fifth metacarpal shaft fracture that did not fulfill criteria for conservative treatment. We treated them with minimally invasive osteosynthesis using retrograde intramedullary headless cannulated screws. Results: All patients showed radiographic healing and had full range of motion of the metacarpophalangeal joint at one month follow up except for one patient who suffered a dorsal mutilating hand injury along with a fifth metacarpal neck fracture. One patient had osteoporotic bone and we could not control height loss with screws, so we had to use k-wires. Conclusion: Minimally invasive osteosynthesis with cannulated headless retrograde screws is a good option to treat neck and transverse diaphyseal fractures of the metacarpals. It confers a stable construct that allows early range of motion and return to activities.
